24 commits since v0.20.0. Patch, not minor: entirely fixes and
hardening on top of last release's session⇄game work, nothing new to
opt into. Headline fixes: three Windows install blockers reported
within hours of 0.20.0 (a false conflicting-host detection, a broken
winget log-path switch, missing package-source instructions),
GameStream/Moonlight compat flipped back to opt-in on fresh installs,
three gamescope Game Mode takeover faults that could black out a
Linux machine or strand it on a host restart, a deactivated laptop
panel misdiagnosed as a blind spot instead of a named stall cause,
and the PyroWave high-bitrate latency-creep bundle (clock re-sync
starvation, wire bitrate overshoot, backlog buildup, ABR probe
false-congestion).
Wire protocol stays at 2, the embeddable C ABI at 13 and the Windows
virtual-display driver protocol at 6, unchanged from 0.20.0 — no
embedder rebuild required, 0.18/0.19/0.20 hosts and clients mix
freely.

`2c69cbda` rewrote StatsSample::mbps's doc comment (goodput → attempted
sealed wire bytes) without regenerating the snapshot, so
`openapi_document_is_complete_and_checked_in` fails on main today. Pure
regeneration, no API surface change: the description and the version stamp
are the only differences.
Until now the host had no signal handling at all: SIGTERM killed it
outright. That is fine for a host that owns nothing — but a managed
gamescope takeover owns the box's session, and on a mask-fragile display
manager (Nobara's plasmalogin) it has STOPPED that display manager for the
length of the stream. Killed there, the host leaves a box with no graphical
session and nothing left to restart it: the crash-restore state lives in
$XDG_RUNTIME_DIR, which logind removes along with the user manager, so not
even the next host start can heal it. `systemctl --user restart
punktfunk-host` mid-stream — or a package update doing it for you — was
enough to strand a box until someone reached a VT.
So SIGTERM and SIGINT now restore first and exit after. The restore runs on
a blocking thread (it shells out) under a 20s grace, well inside systemd's
TimeoutStopSec, and a host that took nothing over exits immediately.
`restore_takeover_now` is the synchronous sibling of the debounced
disconnect restore, and deliberately ignores the keep-alive policy the
latter honors: `keep_alive=forever` pins a session for the NEXT client,
which means nothing once the host that would serve them is exiting. Both
paths now share one `takeover_live()` predicate instead of repeating the
four-way "is anything ours" test.
Checked on Linux: clippy -D warnings on punktfunk-host + pf-vdisplay, tests,
rustfmt.
Field report, Nobara + 0.20.0: switching into Game Mode mid-stream
disconnects the client and the box never lights up again. His journal has
the whole mechanism, ten seconds apart:
12:34:18.9 freed Steam: stopped the display manager for this stream
12:34:29.0 systemd[1685]: Stopping punktfunk-host.service
Stopping the display manager ends the user's last login session. The
packaged host is a `systemd --user` unit, so logind then stops
user@1000.service once UserStopDelaySec elapses — 10s by default on Nobara
— and takes the host with it. The stream dies, the scheduled restore never
runs, and the display manager stays down with nothing left to restart it:
a black box that needs a VT to recover. Exactly the two symptoms reported,
and the intermittency is just whether an active Gaming Mode session was
there to trigger the takeover at all.
It never showed on the repro VM because lingering was enabled there for the
earlier sessionless tests (`Linger=yes` — confirmed on the VM today), which
is precisely the thing that breaks the dependency: logind keeps the user
manager alive with no session. Our KDE/GNOME/Arch setup guides already ask
for it; his box, following the KDE route, did not have it.
So the takeover now ensures lingering BEFORE it touches the display
manager: `loginctl enable-linger` directly (allow_active in logind's own
policy — verified working unprivileged on Nobara), else the packaged helper
gains a `linger` verb that enables it for PKEXEC_UID alone, never a
caller-named user. If neither works the takeover is refused with an
actionable error and managed degrades to attach — mirroring the box's own
session is strictly better than a screen that needs a VT. Hosts that cannot
be reached this way (root, a system unit) skip the check: the cgroup test
is a pure `cgroup_under_user_manager` with a unit test, matched against the
real shapes on a Nobara box (`user@1000.service/app.slice/...` vs a
`session-N.scope`).
Also documents the requirement in the gamescope guide's Nobara section.
Checked on Linux: clippy -D warnings, 78 tests, rustfmt; helper verified
with `sh -n`, and the linger enable/disable round-trip run live on the
Nobara VM.
Two ways the Nobara DM-stop takeover could end a session and leave the box
dark, both found while triaging a 0.20.0 field report (managed round-trip:
"my client disconnects and my monitor doesn't turn back on", intermittent).
0.20.0 is the first release where that box runs the takeover for real —
before it, no package shipped the polkit privilege, so managed always
degraded to attach and never touched the display manager.
Privileged verbs are non-interactive now. `try_stop_display_manager` and
`restore_display_manager` try a plain system-bus `systemctl` first, and
without `--no-ask-password` that asks polkit for INTERACTIVE authorization.
On a box where the host runs inside the user's graphical session, polkit
hands that to the session's agent: a password dialog on the box's own
screen, which during a takeover is off or mid-switch. Nobody sees it,
nobody answers it, and the call blocks on the stream's own thread — the
capture-loss rebuild, or the restore worker — while the rebuild budget
burns. The takeover then lands after the session it was for already ended.
With the flag it fails immediately ("interactive authentication required"),
which is what both callers are already written for: the packaged pkexec
helper (allow_any, no agent needed) takes it from there.
A sentinel with no baseline is not a request. `session_select_requested`
read "no baseline recorded" as "the sentinel appeared during the session" —
but `~/.config/steamos-session-select` is a permanent file, so every box
whose user has ever switched sessions has one. The baseline was recorded
only after a SUCCESSFUL launch, leaving a real window: takeover succeeds,
launch fails, the client retries inside the 5s restore debounce (which the
retry cancels), and the honor gate fires on a months-old write — pushing
the box to the desktop the user never asked for, plus a 120s grace refusing
to relaunch game mode. Now the baseline is taken at takeover too (setting
STOPPED_DM is what arms the gate), and "never baselined" reads as no
request. `SESSION_SELECT_BASELINE` carries both states explicitly, and the
decision is a pure `sentinel_advanced` with a unit test for all six cases.
Checked on Linux: cargo check --all-targets, clippy -D warnings, 77 tests,
rustfmt.
Three upgrades from the on-glass rounds on .173/.221:
- `ddc-open` timing: the handle-ACQUISITION cost per monitor is reported even
when it yields no physical handles — the poller's first contact with a
virtual display, exactly what the DDC-fail-fast driver work changes; the
old code silently skipped handle-less monitors, which on a streaming host
in exclusive topology is every monitor there is.
- Monitors are labeled by GDI device name (\\.\DISPLAYn) so a virtual
display and a panel are tellable apart in the correlation log.
- `extend` mode: one SDC_TOPOLOGY_EXTEND poke — re-activates every
attachable display, i.e. the exact 'non-managed display re-activated'
event the exclusive watchdog evicts. One shot, not a loop: trigger a
reassert round, observe the recovery.

Field A/B (reporter, Legion 5 Pro hybrid, 2026-07-27): the ~2 s capture-stall
metronome IS the exclusive isolate's own doing — deactivating the laptop panel
leaves a dark-but-connected eDP head whose driver-level servicing disturbs the
capture path (~1.7-2.8 s period); `topology: primary` (panel stays active)
stopped it outright (16.3 stalls/min → 0). Our own .221 logged the identical
signature the day before. The detector then steered AWAY from the cause:
connected_inactive filtered to EXTERNAL physicals only, so the one display
that mattered — on a hybrid laptop, the default config — reported as `none`.
- TargetInventory: new `internal_panel` class bit (eDP/LVDS/embedded).
- connected_inactive_externals → connected_inactive_physicals: internal
panels join the suspect list (virtual/indirect stay excluded); a nameless
panel renders as "laptop panel".
- The below-OS METRONOMIC warn names the dark-panel case and its actual
cures (`topology: primary`, `pnp_disable_monitors`) — the old text's
"unplug it" prescriptions are impossible for an internal panel.
- ddc_power_off: a zero-ack sweep now says at INFO that the axis did nothing
(internal panels have no DDC/CI) instead of silently no-op'ing.

In exclusive topology the virtual display is the ONLY monitor on the desktop,
so monitor-control software (the Twinkle Tray / PowerToys PowerDisplay /
Monitorian class) aims its entire DDC traffic — brightness polls,
capabilities-string requests — at OUR monitor. There is no bus and no sink;
the only wrong answer is a slow one (a timeout-shaped failure occupies
win32k's physical-monitor path, serialized per monitor, for its full
duration). Register EvtIddCxMonitorI2CTransmit/Receive and answer every probe
with an immediate STATUS_NOT_SUPPORTED, making the virtual monitor the
cheapest thing on the "bus" to poll. (The receive DDI has no out-arg at the
callback — refusing synchronously refuses the whole transaction.) EDID needs
no equivalent: the OS serves descriptor queries from the blob supplied at
monitor creation without calling the driver.

The exclusive-topology reassert's forced re-commit transiently bounces the
virtual display's mode; the descriptor poller can sample that EVICTION state
and recreate the ring at a mode the recovery chain is about to undo (field
log 2026-07-27 10:30:44Z: hdr=true → false → recreate → recovery restores
true → second recreate). New pf-win-display::topology_churn latch (deadline
semantics — self-expiring, so a lost release can never wedge descriptor-
following off): the watchdog holds it for interval+3s each fighting round and
releases on "stable again"; poll_display_hdr consumes samples but acts on
nothing while held — which also keeps the negotiated-depth pin-back from
issuing a CCD write mid-eviction, where it would fight the reassert itself.
The deliberate recreate_ring_in_place recovery path is unaffected.

The stall-immunity bench needs both stall classes on demand, without a standby
TV or a monitor-tool storm: `ddc` replays the Twinkle-Tray/PowerDisplay-class
DDC/CI traffic (VCP reads, optional capabilities-string requests) through the
win32k I2C path; `modeset` re-commits the current mode with CDS_RESET — the
Level-Two modeset entry that idles the whole adapter with nothing Win32-visible
changing. Every op prints an epoch-stamped took_ms line so host.log stall
reports correlate line-for-line, and the op duration itself measures the
driver's service time per disturbance.

Two stall-immunity hardenings for the swap-chain drain thread (branch-2 of the
disturbance-immunity program — failures in OUR delivery leg, as opposed to
adapter-wide display servicing, which no priority survives):
- MMCSS registration fails under the restricted WUDFHost token on some boxes;
the drain thread then ran UNPRIORITIZED — the whole display's frame pump at
normal priority, starvable by DDC/HPD-servicing DPC pressure into
multi-hundred-ms delivery holes. Fall back to TIME_CRITICAL.
- IddCxSetRealtimeGPUPriority (IddCx 1.9) raises the processing device above
every regular application's GPU priority. Slot availability comes from
raising the exported IddMinimumVersionRequired 4 → 10, which was overdue
independently: the drain loop already calls ReleaseAndAcquireBuffer2 (1.10)
unconditionally, so binding a pre-1.10 framework would dispatch past the
populated IddFunctions table — with 10 an old framework fails the bind
cleanly instead. The product floor is already Win11 22H2 (installer
MinVersion=10.0.22621, whose framework is 1.10), so no supported system
changes behavior.

The shell is a windows_subsystem binary and spawns punktfunk-session with
CREATE_NO_WINDOW + inherited stderr: a normal GUI/MSIX launch has no
console, so every log line — the shell's and the session's whole
receive/decode/present forensic trail — evaporated exactly when a user
hit something worth reporting. The 2026-07 PyroWave latency-sawtooth
report had to be triaged from host logs alone; the deciding evidence
(clock re-sync vs backlog-flush lines) lives client-side.
- New logfile module: %LOCALAPPDATA%\punktfunk\logs\client.log,
the host's rotation convention (10 MB cap -> .old at next start, one
generation), best-effort (no dir -> plain stderr, never a startup
failure).
- The tracing subscriber tees to stderr AND the file (ANSI off — the
file is what users send); startup logs the path.
- The spawned session's stderr is piped through the same tee,
line-buffered — dev-terminal runs keep their interleaved output,
GUI runs finally keep anything at all.
- The --console path and the punktfunk-console.exe MSIX shim forward
the same way (a couch launch has no console either).

Three lines that each sent the 2026-07 PyroWave field triage down a wrong
path, made honest:
- The 'client accepts streamed AUs … will stream per-slice' log fires
before the encoder exists and regardless of backend support (only Linux
direct-NVENC implements chunked polling) — it now states the client
capability only.
- StatsSample::mbps was documented as 'transmit goodput'; it is attempted
sealed wire bytes at seal time — AU bytes + shard framing + FEC parity
(+ PyroWave window padding), not reduced by socket send drops.
- The per-stage split's 'encode' stage is the poll() duration, which is
~0 by construction for synchronous backends (PyroWave encodes inside
submit → its time shows as 'submit') — documented at the split's
definition so 'encode 0.00' stops reading as an instrumentation hole.

The startup speed-test probe deliberately overloads the link (2 Gb/s for
800 ms) to measure capacity. The report tick is suppressed while it runs
and the window anchors are rebased when it ends — but two residues leak
past the rebase: probe frames still pending in the reassembler age out as
frames_dropped for another ~120 ms (the loss-window fuse), and the burst
can latch flush_in_window (a jump-to-live it caused itself). Either one
reads as a SEVERE window: the controller backs off ×0.7 and — worse —
slow start ends at the first congestion signal, permanently.
That is precisely the 2026-07 field report's Automatic session: 20→14
Mb/s exactly one report tick after the probe, then a purely additive
+6 %/4.5 s crawl that took the whole 4.5-minute match to reach 308 Mb/s
on a link the probe had just measured at ~1.2 Gb/s. Slow start (doubling
per clean window to the probed ceiling, 'seconds instead of minutes')
never got to run.
The first post-probe report window is now discarded outright: no
LossReport (probe residue would also spike the host's adaptive FEC), the
standing-latency detector closes it as not-loss-free (its clean-run just
resets), and the ABR is fed nothing.

The pre-decode FrameChannel is strictly FIFO because H.26x reference
chains forbid mid-stream drops — falling behind is only recoverable via
the coarse jump-to-live thresholds (depth ≥6 sustained, or 400 ms behind
the capture clock) at the cost of a keyframe round-trip.
PyroWave has no reference chains: every AU decodes independently, so a
slow consumer can skip straight to the newest queued AU with zero
recovery cost. The pump now flags the channel all-intra for PyroWave
sessions and pop() drains to the newest, which caps any standing
pre-decode queue at ~1 frame structurally — the 2026-07 field report's
780M client could otherwise ratchet a real multi-frame backlog (and with
it the OSD latency) between those coarse thresholds.
Skips are counted separately from losses (they were delivered, just
superseded) and surfaced at debug on the report tick — the OSD 'lost'
line keeps meaning wire loss.

A datagram-aligned PyroWave session inflates the codec bitstream ×1.2–1.3
on its way to the wire — greedy packing of few-hundred-byte atomic block
packets into 1408 B windows zero-pads most window tails, plus the 4-byte
prefixes and FRAG chains. The 2026-07 field report's 1440p60 10-bit
"Automatic" pin of 407 Mb/s put a measured 550 Mb/s on a 1 GbE link;
nothing enforced the pin past the rate controller.
New shared WireBudget (pyrowave_wire.rs, both backends): tracks the real
per-frame AU/bitstream ratio as a ×1024 fixed-point EMA (prior ×1.25,
weight 1/8, clamped ×1.0–×2.0) and deflates the budget handed to
pyrowave's rate control by it, so the windowed AU lands on the configured
rate. Sealed-datagram framing (+4.5%) and FEC parity stay uncompensated —
H.26x sessions carry those on top of the configured bitrate too, and the
pin must mean the same thing for every codec.
Dense (non-chunked) sessions are untouched.

The mid-stream clock re-sync starved on high-bitrate LAN sessions (2026-07
PyroWave-sawtooth field report, RX 9070 XT -> 780M @ 550 Mb/s): every batch
was judged against the CONNECT-TIME RTT, measured before the video data
plane existed, with a 2 ms floor — mid-stream control RTTs on a loaded GbE
link sit above that almost permanently, so batches were rejected for
minutes while the wall clocks drifted apart and the OSD e2e figure ramped
19->150 ms before snapping back on a lucky batch.
Three changes:
- Rounds are spaced 7 ms apart (stamped at send time, so the spacing never
lands in the RTT). An 8-round batch used to complete inside ONE ~6 ms
video burst — all rounds sampled the same congestion state; spacing walks
them across the frame cycle so the min-RTT round finds a quiet gap.
- ResyncGuard replaces the static baseline: the guard band follows the best
RTT the session has evidenced (connect RTT, then min over every completed
batch — rejected ones included).
- Rejection streaks are bounded: after 3 consecutive rejections the best
(min-RTT) batch of the streak is applied anyway. Its queueing bias is at
most ~half its RTT; unbounded wall-clock drift costs more per minute.
Rejections now log at warn with the streak and floor — the starvation
signature is grep-able in exactly the logs users send.

A user found this in their log and had never been offered a choice:
WARN GameStream/Moonlight compat ENABLED (--gamestream): its pairing runs over
plain HTTP and its legacy control encryption can reuse GCM nonces
(security-review #5/#9) — an on-path LAN attacker could MITM pairing or
recover input. Enable only on a TRUSTED network.
They were right. The `gamestream` task carried no `Flags: unchecked`, so it was
pre-ticked; and since a silent install takes the wizard's own task defaults
(1839d756), a winget install turned it on with no checkbox ever shown. The host
warns that this plane is a security downgrade on every single start, so having
the installer enable it by default cannot be squared with our own advice — least
of all on the path where nobody sees a wizard.
Now unchecked, matching `allowpublicfw`, the other task with a security
consequence. A default install therefore lands `PUNKTFUNK_HOST_CMD=serve`, the
native-only host; Punktfunk's own clients are unaffected, since the native
punktfunk/1 plane is always on. Unattended opt-in is `/MERGETASKS=gamestream`.
Scope, deliberately: this changes FRESH installs only. `GamestreamParam` already
omits the flag entirely unless `FreshHostInstall`, so no existing host has its
choice touched by an upgrade, and anyone relying on Moonlight today keeps it.
`DEFAULT_HOST_CMD` (the service's fallback when host.env carries no
PUNKTFUNK_HOST_CMD line at all) is deliberately NOT flipped here: the installer
always writes the line explicitly, so it does not affect a normal install, and
inverting it would silently disable Moonlight for anyone whose host.env lost that
line — a runtime regression that belongs in its own change, if at all.
Docs corrected everywhere they stated the old default, since three of them now
told users the opposite of what ships: the winget Agreement shown BEFORE install
(it said "enabled by default" and gave the opt-OUT override), the Windows
packaging README, and host.env.example. The `--override` example in the installer
manifest is inverted with it (`/MERGETASKS=gamestream` to add, `!` to remove).
Verified: [Tasks] + [Code] compile with ISCC 6.7.1 on the windows-amd64 runner
(all optional features defined), and the winget catalogue rebuilds and passes
29/29 with the edited manifests.
Second field report on 0.20.0's winget path, and independent of the conflict
abort in 37781a61: an INTERACTIVE install through UniGetUI dies before the
wizard with Inno's "Error creating log file: The filename, directory name, or
volume label syntax is incorrect."
`<LOGPATH>` is winget's own token and the only spelling it replaces — the
schema this manifest declares says so verbatim ("<LOGPATH> token can be included
in the switch value so that winget will replace the token with user provided
path"). We shipped `|LOGPATH|`, which is not a token, so winget passed the
literal string to Inno; `|` is not legal in a Windows filename, and Inno refuses
before doing anything else.
Worse than the conflict abort in two ways: it is not confined to silent installs
— it fires in EVERY mode for any caller that requests a log — and UniGetUI
requests one by default, so a GUI user cannot install at all. Confirmed against
the live source, which is serving the broken switch to everyone right now:
curl -s https://winget.punktfunk.unom.io/packageManifests/unom.PunktfunkHost
→ "Log": "/LOG=\"|LOGPATH|\""
Guarded by the suite that exists for exactly this class of defect (a wrong
response shape does not fail loudly — winget just says "no package found"). The
new check accepts an absent Log switch, requires <LOGPATH> when present, and
rejects any |TOKEN| spelling. Mutation-verified: restoring |LOGPATH| fails the
check naming the offending value, and the corrected manifest passes 29/29.
⚠ Fixing the template does NOT fix the live catalogue: it is derived from the
manifest trio attached to each release, so the corrected switch only reaches
users when a release carries it.
Field report within hours of 0.20.0 (HitFrostbite): `winget install
unom.PunktfunkHost` fails with "Installer failed with exit code: 1",
0x8A150006, after the hash verifies and the install starts.
That is Setup aborting on purpose. `StreamHostPresent` counted a conflicting
host as present if its SCM service key existed at ANY start type, OR if a bare
Program Files\<Name> directory existed — so a disabled service, or a folder left
behind by an uninstall, read as a live conflict. 3d893013 then made the warning
a SuppressibleMsgBox defaulting to IDNO so unattended installs could not hang on
it; under winget's /VERYSILENT /SUPPRESSMSGBOXES that default aborts
InitializeSetup, and Inno exits "failed to initialize" = code 1. Net effect:
anyone with Sunshine on disk — the exact audience most likely to migrate — could
not install via winget at all, with no visible reason.
The other candidate for exit 1 is excluded rather than assumed: the manifest
declares MinimumOSVersion 10.0.22621.0 matching the script's MinVersion, so
winget refuses an unsupported OS BEFORE downloading, and the report shows the
hash verified and the install starting. The conflict check is also the only
`Result := False` in InitializeSetup.
Detection now keys on the service's `Start` value (0 boot / 1 system /
2 automatic / 3 manual / 4 disabled), counting only 0-2 — a host that comes up
on its own is the only kind that can take the GameStream ports or load a second
virtual-display driver. Directories no longer count at all: they were the
noisiest signal and the one that survives an uninstall. This makes the installer
agree with the tray, which dropped its always-on warning over a merely-INSTALLED
Sunshine in this same release (3e782852) for exactly the same reason. The
message now says "installed and set to start automatically" and offers disabling
the service as a remedy, both of which are what is actually detected.
A conflicting host running as a plain user process is deliberately not detected:
pure Pascal cannot enumerate processes, it is a runtime rather than install-time
condition, and the host already reports it via the `punktfunk::detect` startup
warning, `detect-conflicts`, and /api/v1/local/summary.
Verified by compiling the [Code] section with ISCC 6.7.1 on the windows-amd64
runner (WithWeb defined, as CI does). That caught two defects in my own first
draft that review would not have: a continuation line STARTING with #13#10, which
ISPP reads as a preprocessor directive ("Unknown preprocessor directive", compile
aborted), and `{commonpf}` written inside a `{ }` comment, which closes it early
since Inno comments do not nest. Both are noted at the sites so they are not
reintroduced.
bun-audit has been red since the advisory published, so it was already failing
before v0.20.0 was cut (same failure on 0323158a). High-severity DoS: unbounded
expansion length causing an OOM crash. All three paths are dev tooling —
orval→typedoc→minimatch, @storybook/react-vite→glob→minimatch, and
nitro-v2-vite-plugin→nitropack→archiver→archiver-utils→glob→minimatch — so
nothing shipped to a user was exposed, but the leg gates every lockfile change.
Done as an `overrides` entry, joining the eight already there for exactly this
purpose. `bun update brace-expansion` is NOT the fix and was reverted: for a
package that is only transitive it adds a spurious DIRECT dependency, and it
does not even resolve the advisory — it hoists 5.0.8 for the new direct dep and
leaves `minimatch/brace-expansion` pinned at the vulnerable 5.0.7.
The advisory's affected range is `<= 5.0.7` across ALL majors with 5.0.8 the
only patched version, so the two nested 2.1.2 copies had to move too — a major
bump for consumers declaring ^2.0.1/^2.0.2. Checked rather than assumed: 5.0.8
is dual ESM/CJS with a real `require` branch in its exports map (2.1.2 was
plain CJS), so those consumers still resolve. Proven by building: the nitro
build is itself one of the forced consumers.
Verified: `bun audit` reports no vulnerabilities, both nested entries are gone
from the lock, and the full CI web sequence is green —
`bun install --frozen-lockfile --ignore-scripts`, `bun run build`, `bun run lint`.
The catalogue-verify step has failed on every stable tag since it landed,
v0.20.0 included: `bash: line 6: GITHUB_REF_NAME: unbound variable`, twice,
then exit 1.
`env:` populates the RUNNER's environment. appleboy/ssh-action executes its
`script` on the REMOTE host over SSH, which inherits none of it — the action
has a separate `envs:` input naming the variables to forward. Without it the
`set -u` at the top of the script turns the first expansion into a fatal, and
the two `curl`s either side report only the collateral: `Failed writing body`
is curl losing its pipe when the `grep` it was feeding died.
The failure is maximally misleading, because everything it guards ALREADY
WORKED: the catalogue is built, tested and shipped in the preceding steps, and
only the proof-of-serving fails. Confirmed by hand against the live source
during the v0.20.0 release — it serves unom.PunktfunkHost 0.20.0 correctly.
The pattern was already right everywhere else: both "Pull and start docs" steps
(deploy-services.yml, docker.yml) pair `env:` with `envs:`. A sweep of the
other three ssh-action steps found no further instance — the remaining two pass
no variables at all.
Reported within an hour of the announcement: `winget install unom.PunktfunkHost`
answers "no package found". That is correct behaviour, not a broken package —
Punktfunk is served from its own REST source, and winget only searches sources
it has been told about. The notes said "after adding Punktfunk's package source
once" without ever giving the command, so there was no way to act on it.
Both commands are now spelled out, the `winget source add` one flagged as
needing an Administrator terminal (it does), and the failure mode is stated
explicitly so someone who hits it recognises it rather than filing it as a bug.
The lead-in is untouched, so the Discord embed for v0.20.0 stays accurate and
this needs no re-announcement — the release body is re-synced from this file.
On-glass on .41: with `game_on_session_end: keep` — "leave it running, nothing
is ever closed" — a deliberate stop ended the game, and a drop ended it ~14 s
later. Both times the LEASE did the right thing (no `ending the launched game`
line); the game died because the virtual display was torn down, and a nested
launch runs inside that gamescope.
So on a dedicated gamescope session the game's lifetime IS the display's, and
keep-alive decides it — not this setting:
* a deliberate stop skips the linger by design, so the game goes at once,
* a drop lingers the keep-alive window, then takes the game with it,
* only keep-alive Forever actually keeps it — and `always` still ends it at
the reconnect window, which is the documented precedence and was verified
(a `forever`-pinned display released at grace expiry, 60.006 s).
That makes the console's promise untrue on the most common Linux setup, so the
card now says so for every option rather than only warning about `always`, and
the docs get the three cases as a table. Worded so a non-gamescope host reads it
and moves on — a desktop-session launch is an ordinary process and none of it
applies.
Not changing behavior here: making `keep` pin the display would pit it against
"a stop must not leave a ghost display", and which wins is a product call rather
than something to decide silently mid-test.

Rendered the Dashboard stories headlessly and looked at them, which is how this
turned up: with no cover the slot was an empty grey rectangle, reading as
something that failed to load rather than something absent.
Plenty of rows will never have art — an operator-typed command has no catalog
entry behind it, a custom entry may carry none, and nothing does until
`/library` has loaded. The slot keeps its fixed size so rows stay aligned when
only some titles have covers; it just holds a gamepad glyph instead of nothing.
117 commits since v0.19.2. Minor rather than patch: the headline is the
session⇄game lifetime binding on both planes and both platforms — the
stream ends when the game does, and optionally the reverse — plus
library metadata, winget packaging for the Windows host, a 64-bit ARM
Linux client, headless `--pair` enrolment, DRM card selection for the
compositor-less presenter, and the ABR/latency de-escalation work, which
changes runtime behaviour on every session.
Wire protocol stays at 2, the embeddable C ABI at 13 and the Windows
virtual-display driver protocol at 6, so 0.18/0.19/0.20 hosts and
clients mix freely and no embedder rebuild is required. The new GameMeta
library fields are optional and flat on the wire.
Notes authored ahead of the tag per docs/releases/README.md, so the
release is born with a body.

A freshly spawned headless gamescope never delivered a single PipeWire
buffer when a game was launched: gamescope only composites (and only on a
composite pushes a capture buffer) when a client paints, and a nested
Steam bootstrap paints nothing until its UI's first frame — far longer
than the 10 s first-frame budget. The native plane's retry ladder then
killed the half-booted Steam on every attempt and started from zero; the
GameStream plane died on its single wait. Reused live displays worked,
which pointed away from the real cause (root-caused on .41 with a raw
pw_stream probe: `sleep infinity` nested → 0 buffers ever, `vkcube`
nested → 60/s immediately).
Every bare spawn now backgrounds the host's own splash client
(`gamescope-splash`, hidden subcommand) beside the nested app: a dark
window with a subtle breathing bar painted at ~2.5 Hz — damage from the
first second, so capture gets its first frame within the budget on both
planes. In `--steam` mode gamescope composites only windows whose appid
is in the root `GAMESCOPECTRL_BASELAYER_APPID` list (live-proven: even a
painting vkcube gets zero composites without it), so the splash declares
itself as the Steam UI (STEAM_GAME=769) and seeds the baselayer iff
unset; Steam's own rewrite at game launch hands composite focus to the
game with no action on our side. PUNKTFUNK_GAMESCOPE_SPLASH=0 is the
escape hatch.
The dedicated Steam launch is also shaped with `-gamepadui` instead of
`-silent`: the nested Steam is Big Picture — the identity gamescope's
`--steam` integration is built around — so the boot shows the gamepad UI
instead of the desktop client window flashing through the stream, and
gamescope's focus rules (game outranks the Steam UI appid) cover what
`-silent` was working around.
On-glass on .41 (Bazzite, RTX 5070 Ti, gamescope c31743d): cold connect +
Balatro launch delivers frames on the first attempt on both a cold and a
torn-down-then-fresh spawn; Big Picture boot → game handover confirmed.

Its child is `sh` running a script that `exec`s a binary outside the install
dir, so neither the image path nor the command line carries the directory — the
host's own child is the only signal there is. Which is exactly the case the shim
window now gates: a live child that might still turn out to be a launcher is not
called the game until that window passes.
So "running" legitimately arrives up to SHIM_WINDOW later than it used to, and
the assertion at 1.5 s was asserting the old behavior. Waiting it out is the
point now, not an accident of timing.
The delay is the deliberate cost of the fix: until the window passes there is no
way to tell "the child IS the game" from "the child is about to hand off". It
shows as a few seconds of `launching` in the console, and only for a title whose
store gave us signals.
.25: the ignored live test passes (Child -> Running -> terminate via the
SIGTERM->SIGKILL group ladder -> Exited, session-end action correctly NOT fired),
full suite 305 passed.
On glass (.41), launching any Steam title over the compat plane ended the
session ~7 s later, before the game had started:
launched app command=steam steam://rungameid/2379780 pid=12699
watching the launched game kind="child"
the launched game is running kind="child" procs=0 <- 3 ms in, zero game procs
the launched game exited -> session ended
Linux launches are `Child` leases: the host spawns the launcher itself. The
watcher counts "my child is alive" as the game running, so the lease left the
waiting phase on its FIRST poll — and the shim reclassification lives in that
phase, so it never got to run. When `steam` handed off and exited, that read as
the game exiting.
The design always called for the shim window ("never fires B from a shim exit")
and the code implements it; the lease had simply moved past where it applies. So
when the store gave us signals to recognize the real game by, a bare live child
no longer counts as the game until that window has passed. With no signals the
child is all we have and still counts immediately — custom commands are
unchanged.
Windows could not reproduce this: it holds no child, so its leases are always
`Matched`, and the whole .173 pass was structurally blind to it. Both planes on
Linux were affected — which is most of the audience for this feature.
Also fixes the live-process fixture, which was CI-red for an unrelated reason:
it copied `/bin/sleep` to a file named `game`, and modern coreutils (uutils on
Ubuntu 25.10+, busybox elsewhere) is a MULTI-CALL binary dispatching on argv[0]
— under any other name it exits instantly, leaving nothing in /proc and looking
exactly like a broken matcher. Verified by A/B: the same test fails identically
on a tree predating these changes.
.25 (Ubuntu 26.04): 305 passed, 0 failed.
`- name: Repair the file: dependency (…)` is not valid YAML — the unquoted
`file: ` reads as a second mapping key — so the workflow has been unparseable
since it was added, which is why re-pushing the tag never triggered a run and a
manual dispatch 500'd. I had put that down to a Gitea tag quirk; it was this.
The failure is invisible from the repo side: nothing validates workflow YAML on
push, and an unparseable workflow simply never runs.
On glass (.173), with a copy of Buckshot Roulette already running: a session
launched the same title, Steam focused the existing instance rather than
starting one, the lease adopted THAT process — and a deliberate stop closed the
player's pre-existing game.
That is the one thing the design says must never happen. The rule was written
and the matcher implements it; the reference instant it filters against just
never arrived. `procscan::launch_stamp` supports Windows, but the wrapper every
launch site calls was gated `#[cfg(target_os = "linux")]` and answered `None`
everywhere else — and `None` doesn't fail, it turns the filter OFF (`find` skips
it), so every process under the install dir became adoptable.
Windows is where this matters most: the host runs as SYSTEM and can see every
process on the box, which is why `procscan/windows.rs` calls rule 1
load-bearing rather than a nicety. Both planes were affected.
No unit test could have caught it — the Linux fixtures pass an explicit
`min_start`, and the Windows live test passes `None` deliberately. So the guard
added here asserts the reference EXISTS wherever processes can be matched, which
is the shape of the failure: silent, and invisible from downstream.
.133: 282 passed (+1), same 4 environmental native::tests failures.
Report: iPad on a gamescope/NVIDIA 120 fps session capped at ~80 fps with
repeat_fps 0, zero loss, capture 0 µs, ASIC 15 µs — and submit p50 at
10.2 ms, ~81 % of the loop period. Under gamescope the host composites
the live pointer into EVERY frame, and a cursor-bearing frame forced the
CPU-synced submit path: a blocking CUDA copy plus a fence-waited Vulkan
blend, both exposed to the running game's GPU load. The "games hide the
cursor" assumption the gate relied on does not hold under gamescope.
The blend is now stream-ordered end to end. VkSlotBlend exports a
timeline semaphore (VK_KHR_timeline_semaphore + external_semaphore_fd)
into CUDA (cuImportExternalSemaphore, new dlopen entries): the enqueued
copy signals it on the encode thread's copy stream, the blend submission
waits for and advances it on the Vulkan queue, and a CUDA-side wait
orders the encode after the blend on the session's bound IO stream — no
CPU sync anywhere, so cursor frames keep the stream-ordered fast path.
Each ring slot gets its own command buffer + descriptor set (written
once) so several ordered blends can be in flight; cursor-bitmap uploads
and teardown quiesce through the timeline. Drivers without the timeline
export keep the previous CPU-synced blend, and any bring-up or per-frame
failure still degrades to "no cursor", never a dropped frame.
Also: the blocking multi-plane copies (the escalated/pipelined mode and
the non-stream-ordered fallback) now enqueue every plane and pay ONE
stream sync instead of one per plane (NV12 2→1, YUV444 3→1) — each
exposed wait costs scheduling latency under GPU contention, which is
what makes the escalation's blocking copies self-reinforcing.
Verified on the RTX 5070 Ti box (driver 610.43.03): all 12 nvenc_cuda
on-hardware smokes green, including the new
nvenc_cuda_cursor_blend_stream_ordered (6 cursor AUs, all ordered,
across a bitmap-serial flip); host suite 301/301; clippy --all-targets
-D warnings clean; struct layouts of the hand-flattened cuda.h params
asserted in tests.

Still -1 on glass. The message was going out; the client was ignoring it.
Which packet-type table a client reads is decided by exactly one thing —
moonlight-common-c sets `encryptedControlStream = APP_VERSION_AT_LEAST(7, 1,
431)` — and we advertise 7.1.431, so every client reads the ENCRYPTED table,
where termination is 0x0109. We were sending 0x0100.
Deriving that from the nonce scheme was the error: `NonceKind` describes how the
GCM nonce is built and nothing else. The two look like the same "is this
encrypted" axis and are not. The HDR message could never have caught it either,
since 0x010e is identical in both tables — so the only symptom was the silence
this whole chain has been about.
Pinned with a test asserting APP_VERSION still clears 7.1.431, because if it
ever drops below, the correct type silently becomes 0x0100 again and the stream
goes back to ending as an error with nothing failing to explain why.
.133: 281 passed (+3), same 4 environmental native::tests failures. The Linux
box is off the network, so the full Linux suite is owed.
Disconnecting the ENet peer stopped the freeze but the client then reported the
session as error -1: a bare disconnect is indistinguishable from the host
falling over, so Moonlight called it a connection failure. Which, from its side,
was a fair reading — we never said otherwise.
The protocol has a word for this. Send the TERMINATION control message with
`NVST_DISCONN_SERVER_TERMINATED_CLOSED` first, then disconnect; the client maps
that to a graceful termination (given it has seen a frame, true of any real
session) and lands the player back in the app list.
Constants verified against moonlight-common-c `ControlStream.c` rather than
recalled, because every way of getting this wrong is silent — the client ignores
an unparseable control message, which reads on glass as the same freeze:
* the type comes from the table the CLIENT chose, so it is derived from the
negotiated nonce scheme (plain 0x0100 / encrypted 0x0109) instead of guessed,
* the reason is BIG-endian (the >=6-byte branch; the short branch is a
little-endian u16, which is GFE's older shape).
`disconnect_later` rather than `disconnect`, so the queued message actually
reaches the wire instead of racing the teardown — which would land us back at -1.
The session's GCM key is cached per tick because ending a session clears the
launch state the key lives in, and this is precisely the message that has to be
sealed after that.
On-glass on .173: a launched game exited, the host tore the session down
correctly — and the client froze on its last frame instead of returning to its
app list.
The host's half was right; it just never said anything. On the native plane
ending a session closes the QUIC connection with APP_EXITED, which every client
renders as "game ended". The compat plane has no such channel: `end_session`
stops the media threads, and stopping a UDP sender is silence, not a signal.
Moonlight holds the ENet control stream for the whole session, so with no word
from us it sat there until its own timeout eventually fired.
The control loop already reacted to the CLIENT disconnecting; it had no path for
the reverse. It now watches for its session being cleared out from under it and
disconnects the peer, which is what Moonlight reads as "the session is over" —
landing the player back in the app list, the same place quitting puts them.
This is the signal every host-side end needed, not just a game exiting: the
management stop and a `/cancel` racing another connection had the same silence.
`winget install unom.PunktfunkHost` after adding the source, and `winget upgrade`
from then on. Windows had no update path at all before this — no self-update, no
package manager — so keeping a host current meant noticing a release and
re-running an installer by hand.
Ships the manifest trio in winget-pkgs' own format (so submitting upstream later
is a copy, not a rewrite) plus a release-time generator that substitutes only
version, URL, hash and release-notes link. Everything reviewable — the silent
switches, the agreements, the installation notes — stays in the checked-in
templates rather than buried in a generator.
Silent installs deliberately take the SAME task defaults the wizard shows: a
per-channel default is a support trap. The disclosures the wizard puts on screen
travel as manifest Agreements instead, shown before install and requiring
acceptance — VB-Audio's bundling grant wants the user to see VB-CABLE's origin
and donationware status, and a silent install shows them nothing otherwise. The
console password can only be pointed at, never printed: it is generated per
install and the notes are fixed at publish time.
Self-hosted rather than the community repo, which gates on Defender/SmartScreen
validation the self-signed installer cert would not clear today. The source is
three endpoints — /information, /manifestSearch, /packageManifests/{id}. The
reference implementation's other twenty are its admin API for mutating a
CosmosDB; a catalogue generated at release time has nothing to mutate.
It runs on unom-1 as a stock bun image with the two .mjs files bind-mounted, the
same shape as the flatpak server, so there is no image to build or pull. The
catalogue is derived from the RELEASES rather than local files: winget resolves
--version and upgrade against the version list, so a source that only knew the
newest release could neither pin an older one nor show an upgrade path from it.
That also leaves no state to drift — re-running the build reproduces it exactly.
NormalizedPackageNameAndPublisher is declared unsupported on purpose. winget
derives it client-side with its own normalization, and a near-miss silently
mis-correlates an installed host; ProductCode is exact and Inno gives us one.
28 checks drive the handler directly, and CI gates on them before anything
reaches the box — a wrong response shape does not fail loudly, it just makes
winget report "no package found".

Three faults that only bite when nobody is watching the wizard — which is how a
package manager always runs us, and how a re-run by hand half-behaves today.
The conflicting-host warning used a plain MsgBox. That ignores /SUPPRESSMSGBOXES
and displays even under /VERYSILENT, so an unattended install onto a box already
running Sunshine/Apollo would sit on a modal dialog nobody can see or click.
SuppressibleMsgBox with an IDNO default aborts instead, which is the honest
answer for a combination the message itself calls unsupported.
The GameStream and Public-firewall choices were re-applied on every run. A silent
run has no wizard, so every task falls back to its script default and the
installer confidently re-asserted it: a user who enabled GameStream had it turned
off again, and one who opened the firewall on Public networks had it quietly
revoked (that task is default-unchecked, so the reset ran the other way). Both
params are now fresh-install-only, keyed off whether host.env already exists.
`service install` already read an absent --gamestream as "keep host.env as-is";
--allow-public-network becomes tri-state the same way, resolving an absent flag
from the marker the previous install recorded. It is strict on the value: a
typo'd =of must not fall through to a marker that may say true, because that
turns a mistyped opt-OUT into leaving Public open.
Also brands the installer "Punktfunk Host" in the strings a user actually sees —
Add/Remove Programs, the Start Menu group, the wizard task text. Paths are
untouched; renaming those would relocate installs and orphan existing config.
Verified on the windows-amd64 runner: ISCC compiles the script (with WithWeb
defined, so the password page parses too), and cargo check + clippy -D warnings
pass for punktfunk-host with nvenc,amf-qsv,qsv.

Emulation-and-beyond libraries need more than a title and a poster. Every
library shape (GameEntry, CustomEntry, CustomInput, ProviderEntryInput)
now carries a shared, flattened GameMeta: platform, description,
developer, publisher, release_year, genres, tags, region, players. All
fields are optional and flat on the wire, so existing library.json files,
provider plugins, and clients keep working unchanged.
- Installed-store scanners (Steam, Lutris, Heroic, Epic, GOG, Xbox) stamp
platform=PC; custom/provider entries carry whatever was authored.
- GET /library grows a ?platform= filter (case-insensitive) beside
?provider=.
- Console: the add/edit form gets a Details section (round-tripping every
field, since update replaces the entry), the poster tile a platform
badge (non-PC only — the store badge already implies PC) and the year.
- plugin-kit: ProviderEntry accepts the same fields (new GameMeta schema,
spread flat); SDK + OpenAPI spec regenerated.
- pf-client-core decodes platform for future client badges.

The publish workflow has been failing at Typecheck with "cannot find module
'@punktfunk/host'" — every import of the SDK, in a job whose previous step built
that very SDK successfully.
bun 1.3 installs a `file:` dependency by copying its DIRECTORIES but symlinking
each top-level FILE to itself: `node_modules/@punktfunk/host/package.json ->
package.json`, a dangling self-reference. So `dist/index.d.ts` arrives intact
while the manifest that points at it does not, and resolution dies at the first
step it takes. The types were never missing; nothing could find the front door.
Replacing that tree with a real copy is the whole fix, and the step no-ops
itself the moment bun links `file:` deps correctly again.
Not a regression from anything in the kit — it has been broken since bun
updated, and went unnoticed because nothing has been published since 0.1.4.
Verified from a clean node_modules: install → repair → typecheck → 20 tests →
build, all green.
A Windows/macOS build compiled the resolved-launch parameter out entirely and
warned about it, because the two uses left were both Linux-gated. Both platforms
want the same value: off Linux `set_launch_command` is a backend no-op and a
library title resolves to no command at all (the interactive-session spawner
launches it by id), so the cfg split was carrying an older distinction that no
longer exists.
Also covers the Windows half of `process_name` with a test — the pure name match
plus a live scan for this test process, since `find`'s early return would
otherwise skip the signal entirely and the test would pass vacuously.
Gates: .133 check + clippy --all-targets clean with no warnings, 5/5 procscan
(incl. live); .21 299 tests + fmt.
The two behaviors are opt-in-shaped in different directions — one on by
default, one off — so the page says which is which, what `always` costs, and
that the keep-alive above it is a different clock governing a different thing.
The precedence rule (a display kept forever stays up regardless) is spelled out
rather than left to be discovered.
The dedicated-game-session blurb claimed game-exit-ends-the-session as its own
feature; that is now true everywhere, so it moves to where it belongs.
Automation gains the `game.running` / `game.exited` rows and a short section on
reacting to a game rather than a stream — the two are usually the same moment
but not always, and anyone who has been polling the host to find out when a game
finished can stop.
docs-site: build + tsc clean.
The host knows what it launched and, after a disconnect, that it is counting
down to closing it. None of that was visible: the console showed a stream with
no game, and a game on its way to being closed was something you found out about
afterwards.
The Dashboard gains a running-game card above the session card — box art matched
against the catalog it already fetches, so no new endpoint and no request on the
2 s status poll. "End now" means the two different things the row's state
implies: a live game ends by stopping its session (what then happens to the game
follows the policy — stopping a session is not licence to close a game), while
one already waiting out its reconnect window has no session left to stop and is
ended directly.
The settings card sits next to the display keep-alive policy because that is the
same question one step out: keep-alive decides how long a *display* outlives a
disconnect, this decides whether the *game* does. The copy says plainly what
`always` costs, that a drop is not someone pressing Stop, and that a display kept
forever is unaffected either way — the precedence rule that would otherwise
surprise someone. Where a build enforces nothing (macOS, no launch path) the
controls are shown disabled rather than hidden: "does nothing here" is
information.
Also fixes the story fixtures, which had gone stale against the `games[]` field
Phase 1 added, and adds a story for the state the card exists for — a game whose
client walked away.
web: build + tsc clean, biome-formatted; en/de messages complete.
A plugin's titles launch through the provider's own client, which hands off and
exits — so the host had nothing left to watch, and both lifetime behaviors went
quiet for exactly the entries a provider contributes. A `ProviderEntry` (and a
manual custom entry) may now carry an optional `detect` hint: install dir, exe,
or process name.
It is deliberately a subset of what the host tracks internally. A Steam appid or
a launcher's environment marker are things the host discovers for itself and
would be meaningless — or dangerous — to take on someone's word; where a title
is installed is something only the provider knows. The host's own findings win
where both exist, so a stale export can never redirect the matcher, and a blank
field is treated as absent rather than as "match everything" — an empty install
dir would otherwise prefix-match every process on the box, and this feature can
end processes.
`process_name` is the weakest of the three and the only one typed by hand, so it
is matched case-insensitively against the image's file name and nothing else:
`retroarch` finds RetroArch, not a helper whose name merely starts the same way,
and not a script that happens to live in a `retroarch/` directory. The
never-adopt-a-pre-existing-process rule still bounds it.
Also: the tray summary gains the running-game row (with the closing-in countdown
for a game whose client is gone — visible at the machine without opening the
console), the SDK mirrors the `game.*` events, and its generated client catches
up with the endpoints Phase 1 added.
Gates on .21: check + clippy --all-targets clean, 299 tests, fmt CI-parity,
openapi regenerated (GameEntry still carries no `detect` outbound); SDK tsc +
54 tests green.
Moonlight sessions had neither direction of the session⇄game binding: a game
exiting left the player looking at a desktop, and a session ending never touched
the game. The machinery for both landed with the native plane; this wires it up.
The compat plane had no way to say "this is over" — RTSP carries no close code —
so `/cancel`, the management stop and a game exiting all looked exactly like a
client vanishing. They now set a session quit flag, which is what lets the
virtual display skip its keep-alive linger for a real stop and what the
end-game-on-session-end policy reads to tell a decision from a network blip. A
drop still lingers, and still gets its reconnect window.
Moonlight can't resume a session, so a client coming back for a game it left
behind does it by launching the title again — that reclaims the waiting game
before anything starts, rather than letting the old window close on the copy the
player is now holding.
Both planes now resolve a launch through one lookup (`resolve_launch`), so a
GameStream title arrives with the same identity and the same detect signals a
native one does; `resolve_session_launch`/`launch_command` were the older,
identity-less half of that and are gone. A Moonlight game also has no
live-session entry to hang off, so the status surface gains a slot for it —
without it the Dashboard would show a stream with no game while one was running.
Gates on .21: check + clippy --all-targets clean, 296 tests (293 + 3), fmt
CI-parity.
Phase 2. The lease, the settings, the events and the status surface were already
platform-neutral; what Windows lacked was a way to see processes and a way to ask
one to close.
`procscan` splits per-OS behind one contract. The Windows matcher is a Toolhelp
snapshot plus each process's full image path (`QueryFullProcessImageNameW`), with
creation times from `GetProcessTimes` enforcing the two rules the module exists
for: never adopt a process that predates the launch, never trust a bare pid. Both
matter more here than on Linux — the host is SYSTEM, so it can see and signal
everything, and Windows recycles pids briskly.
Path matching is case-insensitive and separator-aware, and normalizes the `\\?\`
prefix `canonicalize` adds, without which a store-derived path would never compare
equal to a live image path.
There is no reaper argv and no readable environment on Windows, so a spec carrying
only a Steam appid or an env marker matches nothing rather than falling through to
an empty predicate. Steam's appid instead feeds a **veto**: its per-app `Running`
flag in the user's hive can't be trusted to say a game IS running (Steam sets it
around updates too, and leaves it stale after a crash), but it is exactly right for
refusing to declare one gone. If the matcher can't see a game whose exe sits
outside its manifest's install dir, ending the session would be a false positive
the player feels immediately; honoring the veto only ever leaves a stream up.
Termination asks before it insists, which on Windows needs a detail that fails
silently if missed: `EnumWindows` only sees the calling thread's desktop, and the
host's is session 0, which holds none of the user's windows. So the terminating
thread binds to the input desktop first (the pattern `pf-inject`'s `sendinput.rs`
uses), posts `WM_CLOSE` to the game's visible top-level windows, waits, and only
then calls `TerminateProcess` on freshly re-verified pids. Without the desktop
bind the polite pass finds nothing and every game dies unsaved.
Job Objects, planned as WP2.3, are deferred with the reasoning in the design doc:
every Windows launch either hands off through a launcher or the shell — where a job
would wrap a shim that exits immediately — or is a direct exe whose path we already
know, and wiring one in would touch the `CreateProcessAsUserW` token path the UAC
and secure-desktop work depends on.
Also: the watcher's steady-state poll now re-verifies known pids and only re-scans
the whole table once they all vanish (which still catches a game that re-execs).
On Windows a full scan is an `OpenProcess` per process on the box, so this is the
difference between a negligible and a noticeable poll.
Gates: Linux .21 check/clippy/fmt/293 tests green; Windows .133 check + clippy
--all-targets clean, and the 4 procscan tests pass — including the live one that
finds the test process in the real process table and rejects a wrong creation time.
On-glass Windows (Steam/Epic/GOG/Xbox titles, the unsaved-progress check) still
owed; it needs a box with games on it.

The fixture tests establish that the parsing is right; they cannot establish that
it describes this kernel. Two tests close that gap.
procscan now scans the real /proc for a process it just started, which is the
only version that would catch wrong `stat` field ordering, a broken uid check, or
a mis-read uptime clock. Writing it found something worth keeping: a wrapper
script that `exec`s a binary outside the install dir leaves no trace of that
directory in either the image path or the command line, so the install-dir recipe
cannot see it. A real game's binary lives under its install dir, so the fixture
now models that instead — and the note is in the test for whoever wonders.
The gamelease test drives a real child from Running through a host-requested end
to Exited, and asserts the session-ending action does NOT fire for it — the
difference between "the player quit" (end the session) and "we closed it" (do
not). It needs ~12s to outlive the shim window and the exit confirmation, so it
is #[ignore]d; run it with `-- --ignored gamelease`. Verified on .21.

Found reviewing the riskiest paths of the previous commit.
- An install dir of `/games/x` matched a process running out of `/games/xyz`.
The image-path check was already component-wise and fine; the command-line
check compared raw bytes, so it needed the separator. Two library folders
where one name prefixes the other is not a contrived case.
- Ending a nested game force-releases kept displays, which is not per-display —
so with another client streaming it could retire a display that was never
ours. Skip it while anyone else has a live session: the failure mode becomes a
game that keeps running, which is the default everywhere else anyway.
- A lease nothing polls (no detect signals, or a platform without a matcher yet)
sat at "launching" forever in the console. Report it as running: the host did
just launch it, and with no watcher it is claiming nothing about the exit.
- A game ended after its session was already gone reported no `game.exited` at
all — its watcher had stopped with the session, so nothing was left to emit
it. That is every grace expiry and every `POST /game/end`, i.e. exactly the
ones an operator most wants to see.

Two of the most-asked-for behaviors, and until now the host could only manage a
sliver of one of them: end the streaming session when the launched game exits,
and — when the operator asks — end the game when the session ends.
Ending the session on game exit already worked, but only for a Steam title under
a bare-spawn gamescope. Everywhere else the host spawned a launch and forgot it:
the pid was logged and dropped, so on KWin, Mutter, wlroots or gamescope-attach a
finished game left the client staring at a desktop. Ending a game was not
possible at all — there was no primitive for it.
The missing piece was never plumbing, it was knowledge: a launch says what to
run, not what the game looks like once a launcher has handed off. So each store
now also reports how to recognize its game (DetectSpec, previous commit's
subject matter, folded in here), procscan turns that into live pids on Linux, and
gamelease turns pids into a lifetime — with four kinds covering how the game got
started:
nested gamescope owns it; its display teardown ends the game
child the host spawned it, in its own process group
matched a launcher owns it; recognized by its store's signals
untracked nothing identifies it — both behaviors stay off, and the host
says so once rather than guessing
A child that exits successfully within 5s was a launcher handing off, not the
game: the lease re-resolves to matched (or to untracked) instead of reporting an
exit. That single rule is what keeps steam://, epic:// and playnite:// launches
from ending a session the moment they start.
Ending a game is destructive, so three rules bound it. It is opt-in
(game_on_session_end defaults to keep). A drop is not a decision — `always`
waits out a reconnect window (5 min) that a returning client cancels by
reclaiming its own game, matched on fingerprint and title. And only ever this
session's game: a pid is adopted only if it started after the launch, so a copy
the player already had open is never touched, and every pid is re-verified
against its start time immediately before being signalled, so a recycled pid
never is. Termination asks first (SIGTERM to the group, 10s) and only then
insists.
Also here, because they are the same decision seen from other angles:
- A management stop is now a deliberate stop. `DELETE /session` sets quit before
stop, so it behaves like a client pressing Stop — the display skips its
keep-alive linger instead of lingering for a session nobody is coming back to.
- `/status` reports what is running (games[]), including a game whose session has
gone and which is waiting out its window, so the console can show it and offer
`POST /game/end`.
- New game.running / game.exited events, filterable like every other kind, which
is the whole polling loop of the community plugin this replaces.
- session_status::register takes a named struct: eleven positional arguments,
half of them same-typed Arc<Atomic…>, is a transposition waiting to happen.
Gates on Linux (.21): check, clippy --all-targets, fmt, and 291 tests green.
Windows (Job Objects, Toolhelp matching) and the GameStream plane are phases 2
and 3; both are inert here, as is macOS, which has no launch path at all.

`pf_dualsense.inx` gave all four hardware ids a single %DeviceDesc%, so Device
Manager labelled an emulated DualShock 4, DualSense Edge and Steam Deck pad
"punktfunk Virtual DualSense". The HID layer was always per-type — device_type
picks the PID (09CC for DS4), the report descriptor and the product string — but
the one place a user goes to check said DualSense for every choice, which reads
exactly like the controller-type setting being ignored.
Split into four model lines over the same install section, one description each.
No binding, service or descriptor change; stampinf's 9.9.MMdd.HHmm DriverVer
increments on every build, so pnputil takes the update. InfVerif on the WDK
runner: INF is VALID.
Also correct the Slot.pref comment from the previous commit: emulating a
DualShock 4 gives up adaptive triggers by construction. HidOutput::Trigger is
emitted only by dualsense_proto, and a DS4 has no trigger-effect reports — the
host never generates any to send. Rumble and the lightbar remain.

The "Controller type" setting reached the Hello and stopped there. Every pad then
opened with a GamepadArrival carrying its DETECTED kind, and the host builds each
virtual device from that arrival — the session default is only the fallback for a
pad that never declares one. So "emulate my DualSense as a DualShock 4" put a
DualSense on the host the instant the controller connected, and no amount of
reconnecting helped. Apple and the native clients both; Android already applied
the setting per pad.
The setting now rides the declaration too: explicit wins for every slot, Automatic
keeps per-pad detection so a mixed session stays honest. The physical kind still
drives the LOCAL feedback paths — a DualSense emulated as a DualShock 4 keeps its
lightbar and adaptive triggers, and a Deck keeps its rumble keep-alive.
Regressed in 97c67b26 / 76be4c3e (multi-controller support); ships in 0.19.x.

The CCD isolate verifies "sole active desktop" at commit time and is never
checked again. On a hybrid Intel+NVIDIA box the internal panel is re-activated
moments later (the isolated topology is deliberately not saved to the CCD
database so teardown can restore the user's layout, and the post-isolate
resize/HDR churn — or the panel's own driver, or display-poller software —
re-resolves back to the stored layout). Proven on-glass: seconds after the
verify, CCD showed the panel ACTIVE beside the virtual display while the host
still believed it was exclusive — cursor and windows can land off-stream, and
the lock screen can land on the physical panel.
A group-scoped watchdog now re-queries every PUNKTFUNK_EXCLUSIVE_REASSERT_MS
(default 2 s, 0 disables) while an EXCLUSIVE isolate is live and re-issues the
isolate when a non-managed display crept back, logging who-is-fighting
escalation (3×WARN → 1×ERROR → DEBUG). Gated on a new GroupState.ccd_exclusive
flag so a Primary group's deliberately-lit panels are never "fixed". Cycles
take the state lock via try_lock with a sliced sleep, so teardown's stop+join
under the state lock cannot deadlock and is bounded by ~250 ms.

listGpus gains encoder_pin (PUNKTFUNK_ENCODER when it actually pins something —
unset/auto stay null), and the console's GPU card shows it: a muted note when
the pin is compatible, an amber warning naming the pinned vendor and the next
session's GPU when it contradicts the selection (the host overrides such a pin
at session open — without this field the selection just looked broken). Docs
updated to say the adapter wins.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
On a hybrid box, picking a GPU in the web console whose vendor contradicts a
host.env PUNKTFUNK_ENCODER pin produced an unrecoverable session: the pin won
backend selection while the adapter followed the console, the wrong-vendor
encoder failed deterministically at submit, the reset ladder burned its 5
in-place rebuilds on it, and the client reconnected into the identical wall
forever (~10 s per cycle, no visible reason).
Three legs:
- windows_resolved_backend() now reconciles: a hardware pin whose vendor
contradicts the selected GPU is overridden by the adapter-derived backend
(capture + encode share one adapter, so honoring the pin can only fail);
open_video warns loudly when a pin loses. The reconciliation is a pure,
unit-tested table (resolve_windows_backend).
- the QSV wrong-adapter bind is typed TerminalEncoderError, and the stream
loop's reset ladder ends the session immediately on it instead of feeding a
deterministic config error 5 futile rebuilds.
- the un-pinned path was already correct (verified on-glass: NVIDIA preference
+ no pin = stable AV1 10-bit HDR on NVENC), so the override simply takes the
conflict case onto that path.

`resetCursorRects` wore the host shape only when `hostCursors[st.serial]` hit,
and fell through to `invisibleCursor` on a miss. But a miss is the ROUTINE case,
not a degenerate one, and it is not a reason to hide the pointer:
* State (0xD0) is a per-frame datagram and announces the new serial the moment
the host QUEUES the bitmap on the reliable control stream, so on every single
shape change the client knows a serial before it holds the pixels.
* The shape ring drops the NEWEST under burst (CURSOR_SHAPE_QUEUE = 8) and the
host never re-sends it — it only sends on a serial CHANGE — so a dropped
serial stays un-backed until the pointer next changes shape. Crossing a
toolbar flips arrow/I-beam/hand/resize several times a second, and each flip
mints a fresh serial and a fresh bitmap, so bursts are ordinary.
Either way the pointer BLINKED OUT rather than lagging, and in the dropped case
it stayed gone for as long as the pointer held that shape — reported on glass as
"the I-beam never appears over text fields, every other cursor is fine".
Hold the last worn shape across the gap: only `st.visible == false` (the host
says the pointer is hidden) may hide it now, never a missing bitmap. Worst case
is a briefly stale pointer. This also makes two comments that already claimed
this behaviour true — the shape-rejected warning's "keeping the previous cursor"
and CURSOR_SHAPE_QUEUE's healing claim, both of which were fiction.
Host side is exonerated: on .221 the poller sees the I-beam handle (0x10005,
CURSOR_SHOWING set), and the monochrome AND-over-XOR conversion renders a correct
glyph — black beam, white outline — so the bitmap that goes on the wire is good.

The GDI shape poller rasterises only when the HCURSOR VALUE changes. But Windows
rebuilds the system cursors at a new size whenever the display scale under the
pointer changes, and it does that behind a handle that never moves — the shared
arrow is 0x10003 for the whole session. So the cache latched whatever size the
pointer happened to have when the poller started and never let go.
That window is not rare, it is the norm: a fresh virtual display is created at
Windows' RECOMMENDED scale and only picks up the client's saved
PerMonitorSettings override a beat later, while the poller starts within a
second of the monitor appearing. Sample inside it and the session forwarded —
and composited — a 96 px pointer over a 100 % desktop for its entire life, which
reads on the client as a pointer 3x too large while every other thing on the
streamed desktop is correctly sized. Scaling on the client cannot undo it: the
bitmap is proportional to the video, it is just proportional to the WRONG scale.
Re-read the bitmap's extent on a slow cadence whenever the handle is unchanged —
dimensions only, no pixel copy, 4 Hz — and drop the cache when it moved, so the
next tick re-rasterises and publishes a new serial. Observing the extent itself
rather than a DPI proxy also covers the accessibility pointer-size slider and any
other cause of a same-handle re-render.
Windows-side clippy -D warnings green via scripts/wincheck.sh; on-glass owed.

`args` starts AT the subcommand (main builds it with `env::args().skip(1)`), so a subcommand's own
optional arguments begin at index 1 — cf. `args.get(1)` in the `service` arm. This arm read
`skip(2)`, swallowing the first optional argument.
The documented invocation `hdr-p010-selftest 1920x1080 nvidia` therefore picked up the vendor (it is
in the second slot) and ran at the 64x64 DEFAULT. A size-only `hdr-p010-selftest 1920x1080` parsed
nothing whatsoever and still printed PASS. Nothing warned, because an unrecognised token is the only
thing that errors and no token was ever inspected.
The size is the entire point of the flag: the arm's own comment says heights like 1080 are not
16-aligned and exercise a different driver path. So the self-test has only ever validated the one
geometry that exercises the least, and the sweep's W7 gate — 1920x1080 and 5120x2880 on the RTX box
— could not actually run as written.
Found by running that gate: both sizes printed "HDR P010 self-test (64x64 ...)" with byte-identical
plane layouts (row_pitch=128, expected_total=12288 — those are 64x64's).

Linux CI never compiles `#[cfg(target_os = "windows")]` code, so a Windows-side edit was
unverifiable until the Windows CI job ran or someone tested on a real box. The pf-capture sweep's
Phases 3–6 used an ad-hoc version of this harness in a scratch directory; committing it means the
next Windows change does not have to rediscover the recipe.
The obvious in-tree command fails, and not because of the Windows code:
cargo check --target x86_64-pc-windows-msvc -p pf-capture
dies in build scripts that compile C for the target — audiopus_sys (cmake wants a VS generator),
then ring (needs an MSVC C compiler plus the Windows SDK headers). Both enter through
punktfunk-core's `quic` feature.
So the script generates a workspace whose members are Cargo.toml copies with `src` SYMLINKED at the
real crate directories — nothing to keep in sync, no copies to go stale — plus a ~30-line stub
punktfunk-core carrying only `Mode` and `quic::HdrMeta`, which is provably all the Windows capture
stack uses. rustls, ring and opus never enter the graph. Every path dep that is not a generated
member points at the real crate.
Covers pf-frame, pf-win-display and pf-capture with --all-targets, so the Windows `#[cfg(test)]`
modules are type-checked too. ~10 s cold, ~1 s warm, into target/wincheck (gitignored).
Verified non-vacuous: a deliberate type error planted in a windows-only file
(idd_push/stall.rs) is caught and fails the run.

Phase 0 of the sweep added `clippy -p pf-capture --all-targets` to this workflow, which type-checks
all 19 Windows `#[test]`s and executes none of them. They were decorative.
The workflow's own comment explains why pf-encode's tests cannot run here — nvenc link-imports
NvEncodeAPICreateInstance, which resolves only against the driver's import lib. That reasoning does
not extend to pf-capture: it has no encoder dependency at all (`cargo tree -p pf-capture` lists no
nvidia/ffmpeg/libvpl/pyrowave), so its test binary links against nothing the runner lacks.
Confirmed empirically rather than reasoned: `cargo test --release -p pf-capture` was run on a
Windows dev box against a workspace checkout — it linked, executed and passed, building in ~51 s off
an existing release target dir. --release keeps it in the one C:\t\release tree, so it does not
trip the C1069 disk exhaustion a second debug dep tree causes.
18 of the 19 run here (StallWatch + ring-generation masking, the cursor shape→wire truth table, and
`f32_to_f16`'s rounding-carry/saturation edges); all are pure — no Win32, no device, no desktop. The
19th, `hdr_p010_selftest_intel_1080_live`, is `#[ignore]`d because it needs a real Intel adapter.
This is Windows-only code no other job can execute, so it was the cheapest coverage still on the
table.

`pf_capture::hdr_capture_failed()` had exactly one consumer: `open_portal_monitor`, which uses it to
drop the HDR offer (`want_hdr && !hdr_capture_failed()`). The RTSP negotiation consulted only
`gnome_hdr_monitor_active()`. So once the latch was set — an HDR negotiation timed out, the monitor
left HDR mode between probe and negotiation, NVIDIA EGL not listing LINEAR for XR30, a pre-50 Mutter
— the host kept telling the client HDR while capturing and encoding SDR: `cfg.hdr` flowed to
`open_portal_monitor`, which then silently opened the SDR offer.
The client renders an SDR stream as PQ. Washed out, wrong gamut, and no error anywhere. The latch is
sticky until host restart, so every reconnect repeated it.
Consulted at RTSP honor time rather than folded into `host_hdr_capable()` for the same reason as the
colour-mode probe next to it: that fn is the STATIC serverinfo capability (it decides whether to
advertise SCM_HEVC_MAIN10 at all), and this is a live per-session fact.
The native plane needs no equivalent — `capturer_supports_hdr()` is hard-false on Linux, and the
latch is a fact about the portal capturer, which that plane never uses. Noted in handshake.rs so it
isn't re-derived.
Listed in the sweep's confirmed-defect register as cross-cutting/medium, then absent from every
phase of its implementation plan. Verification is on-glass (force the latch, reconnect a client that
requests HDR, confirm the Welcome/SDP reports SDR).

Upstream landed `fc335b39` (negotiate the cursor around what the encoder can blend) on the same
files this sweep restructured. Merged rather than rebased: the sweep MOVED ~2,000 lines out of
`linux/mod.rs` into `pipewire.rs`/`portal.rs`/`pw_*.rs`, so a rebase would have re-fought the same
conflict in up to nine commits; merging resolves it once with both sides in view. The repo already
carries merge commits (`land/sweep-all`).
Two conflicts, both resolved by keeping BOTH changes:
* `linux/mod.rs` — `PortalCapturer::open` gains upstream's `want_metadata_cursor` AND keeps the
sweep's `PortalSession` teardown, so the portal threads now take `(setup_tx, quit_rx,
want_metadata_cursor)`. The second conflict was upstream editing inside the region Phase 5.1/5.3
moved out; the split wins and upstream's change is ported to where the code now lives:
`choose_cursor_mode`'s new `want_metadata` ladder (4 arms — prefer Embedded when the encoder can't
blend, and warn-then-take Metadata when Embedded isn't advertised) is now in `portal.rs`, taken
verbatim.
* `gamestream/stream.rs` — the pooled-capturer slot keeps upstream's third reuse key
(`metadata_cursor`, beside HDR-ness) AND the sweep's `result.is_ok() && capturer.is_alive()`
re-pool gate. Both guard the same slot against different failures: theirs against reusing a
session negotiated for the wrong cursor mode, the sweep's (L2) against reusing a dead one.
Everything else auto-merged, including the `want_metadata_cursor` thread through
`host/capture.rs`'s facade and `native/stream.rs`'s `session_plan::cursor_blend_for`.
Verified after the merge: workspace `cargo test` green, `clippy --workspace --all-targets` clean on
Linux AND on x86_64-pc-windows-msvc, `cargo fmt --check --all` clean, pf-capture 38/38.

The plan's priority order was "every producer- or OS-controlled parser, blend, geometry guard or
negotiation decision", none of which had a test before this sweep (X3). Phase 5's splits are what
made most of them reachable without a compositor or a driver.
**6.1 `bitmap_extent`** — extracted from `update_cursor_meta`, which is the guard whose own SAFETY
proof says a missing bound "SIGSEGVs inside the PipeWire `.process` callback (a segfault
`catch_unwind` cannot catch)". Every input except the region size is producer-written. 5 tests:
a bitmap that fits (with and without header/pixel offsets); the last-row rule (`stride·(bh−1) + row`,
so a bitmap ending flush against the region is accepted rather than rejected by padding that is
never read — and one byte short is rejected); anything past the region; degenerate geometry; and four
distinct overflow vectors including the near-`i32::MAX` stride the SAFETY comment calls out. One
assertion I first wrote was wrong, not the code — with a single row `stride·0 == 0`, so even a
`usize::MAX`-wide row is arithmetically in range; the test now exercises the ≥2-row case that really
overflows and says why the other is fine (the caller has already capped `bw` at 1024).
**6.2 the composite blits** — 8 tests over `composite_cursor` / `composite_cursor_rgb10`: every
packed `PixelFormat` arm lands the colour in its OWN channels (so a byte-order slip cannot pass);
clipping off all four edges plus six fully-outside positions; zero-alpha, `visible: false` and
no-bitmap-yet all drawing nothing; the integer alpha blend; NV12/Yuv444 declined rather than
mis-blitted; and for the 10-bit path a bit-exact round trip of an untouched pixel (including the two
alpha bits the repack must preserve), the R-at-bit-20 vs R-at-bit-0 distinction between `X2Rgb10` and
`X2Bgr10`, and the same clipping. Plus `decode_bitmap_pixel`'s four byte orders.
**6.4 the pod builders** — 4 tests. The `dataType` bitmask is pinned per Buffers pod, because each
bit is load-bearing in a different direction: the mappable pod MUST include DmaBuf (or gamescope's
modifier-bearing format pod wins and the buffer intersection is empty — a link silently stuck in
"negotiating"), the SHM-only pod MUST exclude it (or Mutter hands dmabufs and the race-free download
path is not), and the dmabuf pod MUST exclude the mappable types (or an HDR session can be handed a
MemFd buffer, which Mutter paints 8-bit ARGB32 regardless of the negotiated 10-bit format). Also:
every pod parses back through `Pod::from_bytes`; the HDR pods carry MANDATORY PQ + BT.2020 +
LINEAR-modifier; and only the NV12 offer pins the colour matrix/range. The `dataType` reader parses
the SPA property layout literally (`key, flags, size, type, value`) — a "find the first
plausible-looking int" heuristic read the `size` word, which is also 4, and reported the wrong mask.
**6.5 `FrameToken` generation masking (W14)** — 2 tests, with `IDD_GENERATION` parked two below the
24-bit boundary so the WRAP is what gets exercised: every minted generation is non-zero, fits the
token's field, and survives the pack/unpack round trip `try_consume` performs; and the cleared-
`latest` 0 sentinel never matches a live generation.
**6.6 the cursor conversion (Windows)** — `convert`'s pixel logic extracted from its GDI plumbing
into `mono_planes_to_rgba` / `apply_and_mask_alpha` / `alpha_is_empty`, which is what makes it
testable at all (the caller needs a live `HCURSOR` and a screen DC). 6 tests: the four-state AND/XOR
truth table in one row; transparency surviving without an invert neighbour; the invert outline
covering all eight neighbours, overwriting only TRANSPARENT ones, and clipping at the edges; the
alpha-less colour cursor taking alpha from the AND mask; and a short mask not panicking.
**6.3 / 6.7** landed with the fixes they guard (`negotiation_plan` in 2.3, `f32_to_f16` in 3.5).
38 Linux tests, up from 6 at the start of the sweep — ci.yml already runs them. 19 `#[test]`s on the
Windows side; Phase 0.1's `--all-targets` lint type-checks them all, but note it does not RUN them
(the workflow lints only), so the Windows ones execute on a Windows box. clippy --all-targets clean
on both targets.

Refactors LAST, after every defect fix, so no behaviour change hides in a move diff — and so the
newly-exposed review surface was already clean when it landed (the WP7 discipline). 28f8fc71's
recorded trap (an inline `use super::X` inside a moved body silently changing meaning) was audited
first: every `use super::` in the moved code is either at module level — where `super` still means
`linux` — or inside a `mod tests` that moved with its parent.
5.1 `mod pipewire` → `linux/pipewire.rs`. It was 1,900 of that file's lines. `mod.rs` is a directory
module, so a plain `mod pipewire;` resolves with no `#[path]`.
5.2 out of that, `linux/pw_pods.rs` (the 7 param-pod builders + `serialize_pod` + the PQ constant
and its test) and `linux/pw_cursor.rs` (`CursorState`, `decode_bitmap_pixel`, `update_cursor_meta`,
`dst_offsets`, both `composite_cursor*`). The pods are the crate's WIRE surface — a missing property
is not a compile error but a link that stalls in `negotiating`; the cursor half is producer-driven
and bounds-critical. Both are now pure enough to unit-test without a compositor, which is what
Phase 6 needs.
5.3 `linux/portal.rs`: the ScreenCast/RemoteDesktop handshake, the cursor-mode choice and GNOME's
BT.2100 probe — the async/tokio/zbus control plane, separated from the realtime half. Zero
re-exports changed: `mod.rs` re-exports `gnome_hdr_monitor_active` at its old path.
5.4 `idd_push/open.rs` (the whole one-time construction path + `SharedObjectSa` + `AttachTexFail`)
and `idd_push/compose_kick.rs`. Read `open.rs` when a session will not START and the parent when one
stops flowing; the steady state stays with the parent by decision. Also moved the ~65-line stall
REPORTING block out of `try_consume` (the hot loop) into `StallWatch::report`, taking its two
correlation counters with it — they were capturer fields nothing else touched.
5.5 `windows/dxgi/selftest.rs`: `p010_reference`, both self-tests, `hdr_p010_convert_bars_on_luid`,
`f32_to_f16` and the two test modules — the validation path, none of which runs in a session. The
two `pub` entry points are re-exported, so `main.rs`'s subcommand and pf-encode's live e2e keep
their paths. (An explicit `#[path]`, like `idd_push`'s children: this file is itself reached through
a `#[path]`, so a bare `mod` would resolve to `windows/selftest.rs`.)
5.6 `CaptureSignals`. The seven shared flags/slots were created in `spawn_pipewire`, `_cb`-cloned one
by one, passed as seven of `pipewire_thread`'s parameters, and then re-declared as fields on
`PwHandles`, `PortalCapturer` AND `UserData` — the same list written four times, each with its own
drifting copy of the doc comment. One `#[derive(Clone)]` struct instead (a refcount bump per field),
which also makes it structurally obvious that producer and consumer share ONE set. And `CaptureOpts`
for the four trailing `bool`s: four adjacent same-typed positional arguments are a
silent-transposition footgun — swap `want_444` and `want_hdr` and it compiles, negotiates the wrong
pod family, and surfaces as a black screen ten seconds later.
5.7 trait shape, targeted: `set_active(&self)` → `&mut self` (it took `&self` only because the flag
happened to be an `Arc<AtomicBool>` — an implementation detail leaking into the contract);
`capture_target_id` ⇒ `resize_output`'s pairing rule stated on both methods and in a cluster note;
one-line cluster headers over the 13 methods.
NOT done from 5.7: taking the gamescope targets as an `open_*` option instead of the trait method.
It would put a Linux-only parameter on the cross-platform `open_virtual_output` and on the host's
`capture_virtual_output` facade — a `#[cfg]`-shaped wart in two shared signatures to delete one
already-`cfg`'d defaulted method whose lifecycle rule 2.5c had already made harmless. Wrong trade
under 5.7's own "no churn for no defect fixed" principle.

**4.1 (W10) — the HDR convert allocated two views and mapped a constant buffer per frame, inside
the ring slot's keyed-mutex hold.** So the driver's publisher sat blocked on that slot while the
host created `CreateRenderTargetView`s and Mapped/Unmapped a 16-byte buffer whose contents never
change. Both are lifetime-of-mode facts, not per-frame ones:
- the two P010 plane RTVs now belong to the out-ring SLOT, built once in `ensure_out_ring`
(`out_ring` becomes `Vec<OutSlot>`). A driver that rejects planar RTVs — the one hard
requirement of this path — therefore fails at ring build, where such a failure belongs, instead
of on the first frame.
- `inv_src` becomes an IMMUTABLE constant buffer filled in `HdrP010Converter::new(device, w, h)`.
The converter is already dropped by `recreate_ring` on every mode change, so it cannot go
stale. This also deletes the `Map`'s silently-ignored failure: it could leave the chroma pass
sampling at a garbage texel size with no error anywhere.
**4.2 (W15) — `sdr_white_level_scale` ran inside the keyed-mutex hold too.** It is a CCD query that
contends the display-config lock — precisely the contention `DescriptorPoller`'s doc says must stay
off the frame path — and `prepare_blend_scratch` called it while holding the slot. Moved to
`refresh_sdr_white_scale`, called at open and after each ring recreate (where the scratch is
invalidated anyway). "Only on scratch rebuilds" is not the same as harmless when the thing being
blocked is the producer.
**4.3 (W11) — `VideoProcessorSetStreamAutoProcessingMode(vp, 0, false)`.** The comment claimed "no
interpolation/auto-processing" while only setting the frame format; auto-processing's documented
default is ENABLED, so vendor denoise/edge-enhancement was free to run inside every SDR
`VideoProcessorBlt` — altering the pixels we encode and spending video-engine time on the
desktop-capture hot path. Now actually disabled, with each call's purpose stated separately.
**4.4 (the Linux CPU-path map cache) is deliberately NOT done.** The plan gates it on measurement
("measure first, and only if the CPU path still matters") and this box cannot measure a live capture
session; it also needs a frame-buffer return path through `FramePayload::Cpu`, which is a larger
change than the rest of this phase. Left for Phase 7's measured pass.

Compile-verified for x86_64-pc-windows-msvc locally (a scratch workspace symlinking the real
sources against a stub punktfunk-core — the `quic` feature's ring/opus C builds are what blocks an
in-tree cross-check). Behaviour is owed the on-glass validation in sweep Phase 7.3.
**3.1 (W1/F3) — the HDR pin asserted a flip it never verified.** `poll_display_hdr` discarded
`set_advanced_color`'s `bool` and then wrote `now.hdr = self.client_10bit` — the DESIRED state in
place of the observed one. On a display that cannot be flipped (the state this file already logs as
"Downgrade point D" at open) that broke in both directions: wanting HDR, the fabricated `true`
differed from `current`, so two poller samples drove `recreate_ring(true, …)` and rebuilt the ring
FP16 while the driver composed 8-bit BGRA — every publish dropped by the driver's format guard,
`recovering_since` expiring, `try_consume` bailing: a permanent 3-second reconnect loop. Wanting
SDR, the fabricated `false` MATCHED `current`, so no recreate ever fired and the ring stayed BGRA
against an FP16 composition — the same dropped-publish outcome, silently. Now it re-reads
`advanced_color_enabled` and follows what the display actually composes, with a one-shot error
naming want/observed/returned. A not-yet-settled read costs one debounce cycle, never a wrong ring,
which is why this does not block the frame path on a settle poll the way `open_on` does. Downgrade
point D's error now carries the same pair, so `Some(false)` (display says no) and `None` (the CCD
read failed) are distinguishable.
**3.2 (W2, W3, W6) — cursor correctness.**
- W2: the poller's desktop rect was captured once at open and used forever, for BOTH the
desktop→frame offset and the `in_rect` visibility test — while both mid-session mode-change
paths (`resize_output`, `poll_display_hdr` → `recreate_ring`) keep the same poller. After an
in-place resize the pointer was clipped to the old rect and offset by a stale origin. It is now
a SEED: the poll thread re-queries on its existing 250 ms reattach cadence, keeping the last
good value on `None` (a transient CCD failure must not park the rect at zero and report every
position invisible), which keeps the CCD call off the encode thread as `DescriptorPoller`
demands.
- W3: `composite_forced` tested `cursor_sender.is_none()`, but §8.6's rationale is "no cursor
CHANNEL" — and the delivery just above it is explicitly allowed to fail non-fatally, which is
precisely the state needing the rescue. It was the one state that skipped it: a negotiated
channel that failed to create or deliver left a cursor-excluded target with NO pointer at all.
Now `cursor_shared.is_none()`, evaluated after that binding.
- W6: `cursor()` degraded poller→shm correctly, but the BLEND path — the only consumer that
matters in the composite model, since the Windows encode loop never attaches `frame.cursor` —
read the poller directly with no `alive()` check and no fallback, so the documented fallback and
the spawn-failure warning were both untrue for exactly those sessions (a dead poller meant
pointer-less frames, not a degraded pointer). One `live_cursor()` now serves all three
consumers and LATCHES the source, because the two keep independent serial namespaces and
interleaving them poisons the client's shape cache.
**3.3 (W4, W5, W14) — recreate hardening.**
- W4: `recreate_ring` committed `display_hdr`/`width`/`height` BEFORE the fallible
`create_ring_slots` (VRAM pressure at a large new mode — exactly when resizes happen), leaving
a failed recreate emitting frames stamped with the new geometry against the old ring, the old
generation and an unchanged header. Slots are built first; nothing after the commit point fails.
- W5: a recreate never cleared the driver's status words, and `wait_for_attach` — the only
classifier of TEX_FAIL/BIND_FAIL and the only source of the LUID rebind — runs at open ONLY. A
stale `OPENED` therefore made a failed re-attach look healthy while the recover-or-drop bail
reported nothing. Now cleared before the Release generation store (plus `status_logged`), and
the 3 s bail prints the live `(driver_status, detail, render_luid)` the way `next_frame`'s 20 s
bail already did. The four-field read is one `driver_diag()` helper instead of four copies of
the same unsafe block.
- W14: `IDD_GENERATION` is a full `u32` but the publish token carries 24 bits and `unpack` masks
what it reads, so past 2²⁴ recreates `tok.generation != self.generation` would be permanently
true — every frame rejected. Masked at the single mint point, and 0 skipped (it is also the
cleared-`latest` sentinel).
**3.4 (W8, W9, W12) — handle hygiene.** `shared_object_sa`'s security descriptor is a `LocalAlloc`
nobody freed: leaked twice per open and once per ring recreate. It is now an RAII `SharedObjectSa`
whose `Drop` `LocalFree`s it and whose `as_ptr()` only lends a borrow — which also makes the
"descriptor must outlive the attributes" rule structural instead of a comment. The PyroWave fence's
shared NT handle, created per capturer and never closed, becomes an `OwnedHandle` (the encoder holds
its own duplicate, so closing ours is safe). `cursor_blend`'s `cbuf_scale` is cached only on a
successful `Map` — caching unconditionally wedged the HDR/SDR cursor scale for the session after one
transient failure.
**3.5 (W7) — `f32_to_f16` swallowed the rounding carry.** `sign | half_exp | (half_mant + round)`
ORs a mantissa carry into bit 10, so for every ODD biased exponent (bit 10 already set) the carry
vanished and the result came back ~2× low: `1.9998779 → 1.0`, `0.49996948 → 0.25`. Only values one
ULP below a power of two are affected — precisely what a gradient test pattern is full of — so this
made `hdr-p010-selftest` FAIL a correct shader. Composed additively, with 4 tests (18 asserted bit
patterns, a round-trip property over the self-test's scRGB values, saturation) — all verified
numerically against a standalone reference on this box, including a scan confirming old-vs-new
diverges ONLY on the carry cases. Phase 0.1's `--all-targets` lint is what lets these compile in CI
at all.

**2.5a (L4) — stop `set_var`ing `XAUTHORITY` from a live multithreaded host.** The old connect
swapped the process-global var around each `RustConnection::connect` under a mutex. That lock
serialises this source against itself and nothing else: `getenv` takes no lock, so every OTHER
thread's read raced it — and the concurrency is by construction, since `attach_gamescope_cursor`
runs while the PipeWire thread is starting up (libspa plugin load, EGL/CUDA init). The primary path
now parses the MIT-MAGIC-COOKIE-1 entry out of the given file itself and hands it to
`DefaultStream::connect` + `RustConnection::connect_to_stream_with_auth_info` — the same two steps
`RustConnection::connect` performs internally, minus its env-derived auth lookup — so nothing in
this process touches the environment. The env swap survives only as a fallback for a file we cannot
parse, and a wrong cookie pick cannot do damage: the server rejects it and the fallback (which does
libxcb's full family/address match) takes over. Sharing `pf_vdisplay`'s process-wide env lock was
not the fix — wrong layer, and it would still not fix `getenv`.
**2.5b (L6) — publish the pointer in FRAME coordinates.** `QueryPointer` answers in the nested
root's space, but `CursorOverlay::x/y`'s contract is frame pixels, and gamescope's `-w/-h` (nested
root) and `-W/-H` (output + PipeWire node) are independent knobs — at `-W 1280 -H 720 -w 640 -h 360`
they differ by 2×, so the pointer drew at a fraction of its real position. The root size comes free
off the setup reply we already parse; the negotiated frame size arrives from the PipeWire thread's
`param_changed` through a new `Arc<AtomicU64>` (`0` = not negotiated ⇒ pass through, as before).
Scaling is computed in `i64` — a 5K coordinate times a 5K width overflows `i32`. Position only: the
bitmap stays at root scale, warned once so a mismatched session is visible.
**2.5c (L7) — the targets are a PROVIDER, not a snapshot.** The list was discovered once, before
the game launched. gamescope creates the game's Xwayland at launch and advertises only the FIRST in
any child's environ (verified on this box: `--xwayland-count 2` makes `:2` and `:3`, only `:2` is
advertised), so the game's display was invisible — and when the connected Big Picture display then
reported "gamescope is not drawing the pointer here", the source blanked the cursor for the whole
game session, which is the exact regression the module doc says it fixed. The worker now re-runs the
provider every 2 s: it adopts new Xwaylands, reconnects dead ones, and `spawn` no longer returns
`None` on an empty list — a stream that starts before the game converges instead of staying
cursorless. The provider is a host-facade closure, same one-way-edge shape as `FrameChannelSender`.
**2.5d (L8) — bound the teardown join.** `Drop` joined the worker unbounded while the worker blocks
in `RustConnection` replies with NO read timeout, so a peer that stops answering but keeps its
socket open hung capturer teardown — on the session path. Now: a completion channel,
`recv_timeout(250 ms)`, then detach with a warning (the thread only touches its own X connections
and an `Arc`'d slot).
7 new tests, all host-runnable: the cookie reader against a hostile `.Xauthority` (wrong protocol,
wrong display, wildcard entry, truncation mid-length-prefix, an over-long length prefix, a missing
file), display-string parsing, and the root→frame mapping incl. the 5K overflow. pf-capture 20/20;

The QSV open-failure fallback (1,400 lines, 23 unsafe, 0 tests) follows the
vaapi.rs treatment: the device-free decisions now live in named functions
with their contracts pinned — the per-vendor zero-copy default matrix (AMF
on-glass-validated on, QSV opt-in), the PUNKTFUNK_FFWIN_POLL_MS
clamp-before-µs-conversion (the 27.7-hour-spin class), the readback routing
table with its mid-stream depth-change guard, the swscale source map, the
QSV display-remoting latency contract (async_depth=1/low_power=1/
look_ahead=0/forced_idr=1/scenario) and the AMF no-B-frames contract, and
the per-vendor zero-copy pool bind flags. A probe smoke rides along
#[ignore]d for the runner. No FFI plumbing chased; no behavior changes.

EncoderCaps::blends_cursor's contract said the HOST must fall back to
capturer-side compositing when a cursor-as-metadata session lands on an
encoder that can't composite — but that host half was never built: open_video
warned and the session streamed WITHOUT a pointer (confirmed on the VAAPI
dmabuf and libav-NVENC CUDA paths; latent on vulkan RGB-direct/native-NV12).
The negotiation is now caps-aware, ahead of capture, on both planes:
* pf-encode grows cursor_blend_capable() — the pre-open dispatch mirror
(sibling of linux_native_nv12_ok) answering whether the resolved backend
composites frame.cursor; its pure core is test-pinned arm by arm.
* Native plane: handshake::cursor_forward grants the cursor channel only
where the resolved backend can blend (the capture-mouse flip makes the host
draw the pointer on demand); denied sessions keep the pre-channel path —
the compositor EMBEDS the pointer, never cursorless, never doubled. The
Welcome's HOST_CAP_CURSOR bit is computed once and read back at both
session-wiring sites instead of recomputed. SessionPlan::output_format
additionally keeps every cursor-blend session off producer-native NV12 (the
arm with no CSC to fold a cursor into), and vulkan RGB-direct now yields to
a cursor-blend session even when pinned (EFC cannot composite; the open
logs the override). Windows plans cursor_blend=false via the new shared
cursor_blend_for() rule — the IDD capturer composites the pointer itself,
and asking the encoder anyway fired the blends-cursor warn spuriously on
every cursor-channel session.
* GameStream plane: the hardcoded cursor_blend=true is gone. The portal
source asks for cursor-as-metadata only when the resolved backend blends,
otherwise negotiates an Embedded pointer (choose_cursor_mode's new ladder);
the capturer pool now also keys on that mode. The virtual-output source
passes false — its capture embeds the pointer where it can.
The per-arm warns in vulkan_video (RGB-direct, native-NV12) are now
structurally unreachable and removed. open_video's post-open check stays as
the single backstop for what planning cannot see: a Vulkan-open falling back
to VAAPI mid-session, and the gamescope residual (no embedded mode exists
there, so a never-blending backend — H.264-on-AMD VAAPI, software — still
streams cursorless; fixing that needs a compositing stage, deliberately not
built in this pass). Zero-copy is preserved throughout — every fallback is a
capture-negotiation change, never a readback.

**2.4 — buffer geometry correctness on the Linux CPU path.**
L5: the self-mmap de-pad mapped the fd from offset 0 and then indexed by `chunk.offset()` ALONE,
ignoring `spa_data.mapoffset` — where that spa_data's region actually begins inside the fd. For a
pooled-memfd producer (every buffer a slice of one fd) it therefore read the WRONG buffer, and the
`needed > avail` guard could not catch it: `avail` came from the whole-fd mapping, so it was ample
for any single buffer's span. PipeWire's own MAP_BUFFERS slice (the fallback) was always correct
because it already starts at `mapoffset` — only the hand-rolled "fix" path was wrong, so the two
paths now compute their base separately (checked add; both halves are producer-controlled).
L15: when `fstat` failed, the mmap length was invented as `offset + needed` — producer-controlled
geometry. That defeats the entire point of the fstat (the "buffer smaller than the frame span"
guard then compares against the number the producer just supplied) and can map, and read, past the
end of the object — a SIGBUS, not an `Err`. Without a real length we now decline to self-map and
let PipeWire's own slice serve, which is bounded by construction.
L12: `bytes_per_pixel()`'s catch-all answers 4 for NV12, so a producer-native NV12 buffer computed
`row = 4w` against a stride of ~w and ALWAYS tripped the stride guard — reporting "chunk stride <
row", i.e. blaming the producer for a host limitation. NV12 cannot be de-padded on this path at all
(plane 1 is not even in `datas[0]`'s span), so reject it with a message that says which side is at
fault and under what condition the NV12 offer is valid.
L14: `spa_meta_bitmap` was read field-by-field through an aligned `*const` at a
PRODUCER-controlled offset, with a SAFETY comment asserting an alignment the code never
established. One `read_unaligned` of the `Copy` POD instead.
**2.6 — hand-off semantics (L9, L10).** The frame channel was `sync_channel(8)` + `try_send`, i.e.
drop-NEWEST, while the trait documented drop-oldest. Neither remedy the plan offered works: a
`SyncSender` cannot pop, so "drain one and retry" is not expressible, and shrinking the bound makes
staleness WORSE, not better (with bound N the queue holds the first N frames of a stall and
everything after is discarded, so a larger N actually yields a fresher frame — the defect is the
discarding, not the depth). Replaced with a one-deep OVERWRITING mailbox plus a depth-1 wakeup
channel: publishing overwrites, so a stalled consumer loses the intermediate frames and is always
handed the freshest one. `next_frame` used to return the OLDEST of eight stale frames.
Falls out of it:
- `wait_arrival` now honours its documented "must NOT consume" contract by peeking the slot. The
`pending` field existed only to stash a frame the un-peekable channel forced it to consume;
it is gone.
- a queued `CapturedFrame` can own a dup'd dmabuf fd or a CUDA buffer, so the old 8-deep backlog
could pin eight compositor buffers. One-deep by construction now.
- L10: `set_active(false)` flushes the mailbox, so a reused capturer no longer opens the next
stream with the previous session's last frame (wrong content, and a `pts_ns` from the old
clock). Two lines, where flushing a queue + a `pending` stash was fiddlier.
- the producer-liveness signal moves to the wakeup channel's `Disconnected`, and a final frame
left in the slot as the thread exits is still served before the error.

A caps field nothing reads is a contract nobody honors — and this one shipped
write-only: its single reader anywhere in the workspace was a hardware-gated
assertion inside pf-encode's own AMF smoke test. Both planes send the static
HDR grade out-of-band unconditionally (the native 0xCE datagram per keyframe,
the GameStream 0x010e control message), every first-party client reads
exclusively that path, and none parse in-band SEI — so the host decision the
field was reserved for (suppress out-of-band when the encoder embeds) can
never validly exist. The field's doc contract had also rotted in two
directions: it claimed set_hdr_meta no-ops when false (native AMF and QSV
consume it regardless) and that only Windows direct-NVENC attaches in-band
metadata (AMF and QSV do too). The in-band SEI/OBU emission itself is
untouched — it stays a bonus for stock decoders, documented at the emit
sites; the trait docs now describe the real routing.

**2.1 (L1) — the portal thread leaked a live screencast session.** It parked on
`future::pending()` and `Drop` stopped only the PipeWire thread, so every dropped portal capturer
permanently leaked a thread + a 2-worker tokio runtime + a zbus connection — and because dropping
that connection is what ends the compositor's cast (ashpd's `Session` has no `Drop`), the
COMPOSITOR-side session leaked too. GameStream drops the pooled capturer on every HDR↔SDR
reconnect flip and opens a fresh one, so the sessions accumulated: exactly the "second conflicting
screencast" the pooling exists to prevent. Both portal threads now park on a `oneshot::Receiver`
and `PortalSession::drop` fires it, then waits — BOUNDED (750 ms, then detach with a warning) —
for a completion signal the thread sends after its runtime has been dropped. Bounded because
teardown runs on the session path and the thread may be inside a D-Bus round-trip: an unbounded
`join()` there would hang the host rather than leak. Every early-return path in `open` drops the
session too, so a failed PipeWire spawn no longer strands a fresh cast.
**2.2 (L2) — a dead capturer was pooled forever.** All three of the portal backend's terminal
states are sticky and observable only by consuming a frame, and `Capturer` exposed no health
predicate, so GameStream re-pooled unconditionally — after `result` was already an `Err`. One
zerocopy-worker death or one compositor restart therefore wedged GameStream portal video at 10 s
per reconnect attempt, permanently (that path has no rebuild closure). Adds
`Capturer::is_alive()` (default `true`), implemented for `PortalCapturer` as
`!broken && streaming && !thread.is_finished()` — the third term catches a dead PipeWire thread,
which is otherwise indistinguishable from an idle desktop. A static desktop stays `Streaming`, so
an idle-but-healthy capture is never reported dead. The host re-pools only on
`result.is_ok() && capturer.is_alive()` and logs which of the two retired it. Both halves ship
together: either alone leaves the wedge reachable.
**2.3 (L3/F1) — a "VAAPI" downgrade latch was really a global zero-copy kill switch.**
`spawn_pipewire` hand-mirrored the thread's `vaapi_passthrough` decision and the copy omitted
`raw_dmabuf_import_disabled`, so once that latch fired the capturer still believed it had made the
passthrough offer while the thread had already fallen back — and its timeout branch then latched a
downgrade for an offer nobody made. That downgrade was `note_vaapi_dmabuf_failed`, which fed
`pf_zerocopy::enabled()`, so ONE failed negotiation dropped every later session on the host — the
NVENC EGL→CUDA path included — to CPU capture until restart. And since the raw-passthrough offer
is also the PyroWave one on ANY vendor, a single PyroWave negotiation timeout was enough to do it
on an NVIDIA box.
Two fixes, both structural:
- `negotiation_plan(NegotiationInputs) -> NegotiationPlan` is now the ONE resolver, consumed by
the thread AND by `spawn_pipewire` — the mirror is deleted, not re-synced (WP7.6's shape), so
the drift class is unrepresentable. It is pure (every env/latch read is an input), which is
what makes it testable; the runtime-dependent half stays a method (`want_dmabuf` needs the
modifier list the importer's construction actually yielded). The redundant `importer.is_none()`
term goes: `build_importer` already excludes the passthrough, and that term is what made the
decision look impure enough to "need" a mirror. `PUNKTFUNK_FORCE_SHM` was ALSO read in both
places; now once.
- the capture-side downgrade becomes `pf_zerocopy::note_raw_dmabuf_negotiation_failed`, which
latches `RAW_DMABUF_DISABLED` — gating only the raw-passthrough decision. `enabled()` is now
the env var alone, and `VAAPI_DMABUF_FAILED` is deleted.
Also (L13, needed by 2.3's plan inputs): `PUNKTFUNK_PIPEWIRE_NV12` honoured only the exact string
`"0"`, so `"0 "` or `"false"` read as force-ON — the bug class of ed525c4c. pf-host-config's
explicit-off grammar is now exported as `env_on()` and the four in-crate copies (`PUNKTFUNK_
ZEROCOPY`/`_10BIT`/`_444`/`_CHACHA20`) plus this new caller share it.
7 new tests pin the four invariants that were prose-only comments, plus the latch property that
made the mirror wrong. pf-capture 13/13; workspace clippy --all-targets clean on Linux and on

The fallback backend under Vulkan Video — and the only AMD/Intel H.264 and
10-bit/HDR encoder — had 1,300 lines, 26 unsafe blocks, and zero tests. The
device-free decisions now live in named functions with their contracts pinned:
the entrypoint ladder + LP_MODE latch round-trip (the cross-GPU session-killer
and the 8-bit-pins-10-bit under-advertisement are both key'd tests now), the
PUNKTFUNK_VAAPI_LOW_POWER / _ASYNC_DEPTH grammars, the VUI ↔ scale_vaapi
colour agreement (the Mesa-BT.601 hue-shift pin), the honest-downgrade depth
table, the HEVC-Main10-only explicit profile, and the 10-bit probe gate.
Probe + CPU-path encode round-trip ride along as #[ignore]d hardware smokes

Every item here is prose that actively misdirects a maintainer or an operator. Landing it before
the defect fixes means those diffs get reviewed against accurate comments.
1.1 (X5) — split two merged doc blocks that documented the item ABOVE them: `hdr_meta`'s whole
contract was glued onto `fn cursor()` in lib.rs (leaving `hdr_meta` undocumented), and
`hdr_p010_selftest_at`'s was glued onto `hdr_p010_convert_bars_on_luid` in dxgi.rs. rustdoc for
the trait's central HDR contract was simply wrong.
1.2 (L9 doc half) — the `Capturer` trait doc advertised a "bounded drop-oldest channel". The
Linux portal's `sync_channel(8)` + `try_send` is drop-NEWEST: under a consumer stall the arriving
frame is discarded and the encoder gets the stalest queued one. Say so. (Phase 2.6 changes the
behaviour; this commit only stops the doc from lying about today's code.)
1.3 — delete the DONT_FIXATE claim from the dmabuf offer comment. `build_dmabuf_format` emits a
plain MANDATORY `ChoiceEnum::Enum` and `param_changed` re-emits nothing, so there is no two-step
DMA-BUF handshake here; libspa 0.9's `ChoiceFlags` cannot even express DONT_FIXATE. Recorded as a
real follow-up instead of an implemented thing.
1.4 — `mainloop.run()` no longer "blocks until process exit": the quit channel attached above it
stops the loop from `PortalCapturer::drop`.
1.5 (L11) — the 6-arm negotiation log ladder told a fully zero-copy PyroWave session "VAAPI
encode with the CPU capture path — zero-copy was disabled", one line after logging that it had
advertised the PyroWave device's dmabuf modifiers: the passthrough arm was gated on
`pyrowave_modifiers.is_empty()`, so the pyrowave case fell through to the CPU warning. Ungate it;
the CPU-path arm is now reachable only when no dmabuf is advertised at all, which is what it
claims. Its parenthetical also gains the third real cause (the session asked for CPU frames).
Control-flow-neutral for every other combination.
1.6 (W13) — `kick_dwm_compose` claimed a "sub-millisecond" round trip while its
cursor-on-a-sibling-display branch sleeps 35 ms on the CALLER's thread. State the cost on the
function and at both call sites, including which one is on the live frame path.
1.7 (W16) — DDA-era residue, DDA having been removed:
- retarget the win32u hook's rationale + all four log strings: its job is no longer "keep DDA on
one adapter" but "keep the virtual display on the adapter SET_RENDER_ADAPTER pinned" (a DXGI
reparent surfaces as the driver's TEX_FAIL render-adapter mismatch). The hook stays installed.
- the per-monitor-v2 DPI awareness rationale likewise: not DuplicateOutput1's E_ACCESSDENIED any
more, but keeping cursor/window coordinates in the PHYSICAL pixels the host's CCD geometry
(`source_desktop_rect`, `desktop_bounds`) is already in.
- `HYBRID_HOOK_HITS` was write-only. Surface it as `hybrid_hook_hits()` on the IDD-push open
line, which is the first point where DXGI has actually been exercised — the patch-readback
check proves the bytes landed, only this proves DXGI reaches the export.
- delete `hdr_p010_selftest()`: an unreachable 64×64 wrapper (main.rs calls
`hdr_p010_selftest_at`); its description moves onto the function that survives.
- `VideoConverter`'s docs promised a P010/BT.2020 output and a live scRGB input path. It pins
`YCBCR_STUDIO_G22_LEFT_P709` unconditionally and its only caller always passes
`scrgb_input: false`.
1.8 (X7) — the native handshake's 4:4:4 gate comment stated the OPPOSITE of what
`pf_capture::capturer_supports_444` returns on Windows ("delivers subsampled NV12/P010 today, so
it returns false there" — it forwards `resolved_backend_ingests_rgb_444()` and the IDD ring passes
BGRA through for an SDR 4:4:4 session).
No `.rs` behaviour delta: comments, doc comments and log strings, plus 1.5's control-flow-neutral
ladder and 1.7's counter accessor. Linux tests 6/6; clippy --all-targets clean on both targets.

vulkan_cpu_img_survives_a_source_size_change drove MISMATCHED source
sizes through the then-lenient CSC arm as its vehicle for the staging
cache hazard (format-only-keyed cpu_img → OOB copy while submit said
Ok). e3354b6d's guard — correctly the equality check every sibling arm
always had, against the MODE, not the coded extent, so the padded
render-vs-coded tolerance in the direct arms is untouched — makes that
scenario unrepresentable through submit and broke the test on main
(.25 layers baseline read 13/13 instead of 14/12).
Replaced by vulkan_csc_refuses_a_mismatched_source: refusal pinned in
BOTH directions, plus the property that actually needs proving — a
refused submit does not WEDGE the session (the bail lands after step
1's frame-type bookkeeping; the next well-sized frame must still
encode, and an AU must come out). Verified on the 780M under
validation layers: 8/8 vulkan tests, full-suite baseline restored to
14/12.
The WP4.2 size-keyed staging stays as belt-and-braces; the hazard it
fixed is now structurally unreachable through submit.

Gate for the rest of design/pf-capture-sweep.md: today half this crate is compiled by no CI job
at all, so the Windows-side findings can't even be type-checked.
0.1 (X1) — windows-host.yml lints `-p pf-capture --all-targets`. The host lint above it builds
pf-capture only as a DEPENDENCY, so its `#[cfg(test)]` modules were never compiled anywhere: the
5 StallWatch tests, the DXGI HDR self-tests and the cursor-conversion tables were dead code in
CI. The workflow's own comment already diagnosed this blind spot and fixed it for pf-encode;
pf-capture never got the same treatment. No features on this crate, so no feature juggling and
no extra dep tree.
0.2 (X2) — `#![deny(unsafe_op_in_unsafe_fn)]` beside the existing
`deny(clippy::undocumented_unsafe_blocks)`. The crate declares "every unsafe block carries a
SAFETY proof; enforce it" in ten file headers, but in edition 2021 that lint has nothing to fire
on inside an `unsafe fn` — so the hardest FFI in the crate was exempt from its own program: the
ring/slot construction, the fence signal, the blend scratch, and every D3D converter ctor/convert.
119 operations across 16 functions now carry a proof. `shared_object_sa` loses its `unsafe`
marker instead (it states no precondition — only its RESULT is a raw pointer, which is the
caller's business).
0.3 (X4) — drop the crate-wide `#![allow(dead_code)]`. Verified: zero warnings on either target
without it, so it was hiding nothing the lint can see (W16's dead items are `pub`/written-once,
so they need Phase 1.7's deletion instead).
No behaviour change: only lint attributes, `unsafe { }` scoping and comments.
Linux `cargo test -p pf-capture` 6/6, clippy --all-targets clean on both targets (Windows
verified by cross-checking x86_64-pc-windows-msvc locally).

Rides on 25765c53 (the concurrent session landed the same typed-errno
fix first — this branch's twin commit was dropped in the rebase; these
are its surviving residuals):
- Two tests pinning what the ladder's step-down rests on: the typed
ffmpeg::Error survives with_context layers as a downcastable source
(an eager format! anywhere between open_with and the ladder would
silently break it), and the phrase WITHOUT the type no longer
classifies.
- The CudaHw::new eager-format guard note: those bail!s must NOT be
converted to typed errors — a hwdevice/hwframes EINVAL is a config
error no bitrate can fix, and enrolling it would burn ~10 doomed
opens before surfacing the real failure.

Both Linux Vulkan encode backends named QUEUE_FAMILY_FOREIGN_EXT as the
acquire barriers' src family without ever enabling the extension —
spec-invalid on every device, tolerated by RADV. The audit filed
vulkan_video's three sites; pyrowave's fresh-import acquire had the
identical defect on its own device (critic catch).
Enable when advertised (a fresh open-time enumerate — the rgb probe's
is a probe-local and skipped entirely on native-NV12, so there was
nothing to reuse; pf-presenter/dmabuf.rs is the in-repo precedent that
already enables this extension). Not advertised → the core-1.1
QUEUE_FAMILY_EXTERNAL conservative substitute, chosen once at open and
warn-logged (no fleet hardware takes that arm; such devices were never
valid targets before). All four sites are acquire-only (src=FOREIGN,
EXCLUSIVE images, oldLayout=UNDEFINED) — the swap is index-only.
On-glass: 780M under validation layers — vulkan smokes + pyrowave
smokes green, FOREIGN advertised and enabled, no fallback engaged.
Shared ext_advertised helper in vk_util (cfg = the union of both
consumers) with a unit test.

Verified against nvEncodeAPI.h's own splitEncodeMode doc (user-prompted
— the audit's 'exclusive for HEVC' one-liner deserved checking):
- H.264: split 'is not applicable' — hard-DISABLE the mode so the
written config, CeilingKey, the split diagnostic log and the
rejection-retry stay truthful (the retry used to re-open a
byte-identical session after an H.264 'split rejection'). The libav
path's operator arm gains the codec gate its auto arm always had.
- HEVC: split 'not supported if … subframe mode' — when WE force split
(TWO/THREE/AUTO_FORCED, the 4K120 throughput lever), sub-frame yields
with a logged escape (PUNKTFUNK_SPLIT_ENCODE=0 chooses sub-frame).
⚠ Keyed on FORCED modes only, never != DISABLE: AUTO(0) is the
resolver's fallthrough for every sub-950Mpix session, and the wider
key would have disarmed the Phase-3 chunked-poll feature fleet-wide
(critic catch). Under AUTO the driver arbitrates — the shipped state.
- AV1: untouched — per-tile sub-frame + split are legal together.
The arbitration is a pure nvenc_core fn called by each backend BEFORE
the ladder, the ceiling key and the chunked-poll latch — all three see
the post-arbitration truth. A drop inside build_init_params would have
left poll_chunk busy-polling its whole budget every AU (numSlices stays
0 without reportSliceOffsets; both loop exits dead — critic catch).
Linux latches subframe_forced beside subframe_on at query_caps (no env
re-reads after open); Windows records the arbitrated state so
reconfigure presents exactly the params the open had (also closes the
pre-existing mid-session env-flip hazard there).
Truth-table tests in nvenc_core; PUNKTFUNK_NVENC_SUBFRAME documented
(it never was); PUNKTFUNK_SPLIT_ENCODE row updated.

The bitrate-probe ladder stepped down on format!("{e:#}").contains(
"Invalid argument") — an English substring over the WHOLE context chain,
which also fired on any other wrapped EINVAL (e.g. a CUDA-context errno)
and gated a ~10-step ladder on strerror wording. The root ffmpeg::Error
survives the anyhow chain; downcast and match Error::Other{errno:EINVAL}
instead. Same fix for the intra-refresh ENOSYS probe in the open path.

The backends deliberately turn a wedged GPU into a bounded error so the
caller can reset in place, but only the native plane ever did: on the
GameStream path every submit/poll error propagated straight out of the
video loop, costing Moonlight clients a full disconnect/reconnect. Port
the native ladder (bounded resets + backoff + silent-wedge watchdog,
same field-lesson backoff curve).
Also keep the drop-recovery keyframe armed until it actually EMITS: it
was consumed on read, so the coalesce gate could swallow it for good —
leaving duplicate wire indices in the encoder's reference table for a
later RFI to anchor on, exactly the stale-anchor case rfi.rs exists to
prevent, and it opened only under congestion + loss, which is when RFI
fires.

The CSC path was the only backend arm that took frame.width/height on
trust: the shader samples with clamped 1:1 texelFetch, so a mismatched
frame silently streamed a cropped/edge-padded picture where every
sibling errors into the encoder-rebuild path. The import cache now also
carries the extent it imported at (a (st_dev, st_ino) hit alone doesn't
prove the allocation still matches) and is dropped on reset().
reset() opened with an untimed device_wait_idle on the one thread whose
every other wait is capped at ENCODE_FENCE_TIMEOUT_NS for exactly this
reason — reset() runs BECAUSE the GPU looks wedged. Both vulkan-video
and pyrowave now bound the wait and report "no in-place rebuild" on
timeout instead of parking recovery on the suspect device; Drop keeps
the unbounded wait (teardown must stay memory-safe against a wedged
device).

The ~820-line tail of free builders — make_frame/make_frame_csc/
make_frame_common, make_video_image, probe_rgb_direct, the H.265/AV1
parameter-set writers and the AV1 bit-writer — moves to a #[path] child
module, the amf_sys.rs shape: the child sees the parent's private items
(Frame and friends), so the split costs zero visibility churn. Six
parent-called items went pub(super); five stay child-private (dead_code
is per-item and each is used within the child). vulkan_video.rs drops
5,292 → 4,489 lines and the construction unsafe gets its own review
surface; steady-state encode logic stays in the parent.
⚠ Trap recorded for future child-module splits: inline `use super::X`
statements INSIDE moved fn bodies silently change meaning (super shifts
one level) — vk_av1_encode/vk_valve_rgb imports needed crate:: paths.
Proven on-glass, not just compiled: all 8 vulkan GPU smokes green under
the validation layers on the 780M post-split (H.265 + AV1, RGB-direct,
CSC, CPU paths — every moved constructor exercised).
nvenc_cuda.rs and qsv.rs are DECLINED the same treatment, with evidence
in the handoff doc: no equivalent self-contained seam — their candidate
regions are ~150-line loader/accessor clusters interleaved with the
encoders' own state types, and a thin-forwarder impl split is exactly
the churn a no-defect phase penalizes.

The Linux backend decision existed as open_video_backend's string match
plus five partial hand-copies (the zero-copy-plane gate, the pyro
advertisement gate, the software advertisement pin, the vulkan pref
ceiling, resolved_backend_is_gpu). Windows solved this long ago —
windows_resolved_backend() is consumed by its dispatch AND its mirrors,
with labels still stamped at the open sites. Linux now has the twin:
resolve_linux_backend (pure, lazy auto probe) + linux_resolved_backend
(config wrapper, unknown→auto exactly as every mirror's old `_` arm).
⚠ This deliberately DEVIATES from the audit's shadow-assertion
prescription, on both critics' findings: the shadow had no execution
venue (open_video had ZERO test call sites; shipped hosts are --release)
— unfalsifiable ceremony — and the file's own Windows half proves
dispatch-consumes-resolver is safe: the mgmt record is protected by the
label-from-the-open-site convention, not by resolver avoidance. One
consumed table beats two tables plus an inert cross-check.
Preservation riders from the critique, all applied:
- pref_ceiling KEEPS its cfg!(vulkan-encode) branch (the resolver is
feature-blind; dropping it re-creates advertise-then-die-at-open).
- linux_zero_copy_is_vaapi's Vulkan|Software arm preserves the old `_`
fallthrough EXACTLY — the vulkan-on-NVIDIA capture-plane mismatch and
the software twin are FILED in the design doc, not fixed here.
- resolved_backend_is_gpu splits as linux + not(any(windows, linux)) —
never a target list, so no exotic target loses the fn.
- The auto probe is lazy (impl FnOnce) — explicit prefs stay zero-probe
(/serverinfo polls through these mirrors), pinned by a panicking
closure in the resolver test.
New coverage: the full alias table pinned, and a GPU-free dispatch test
through the real open_video_backend (software arm, vendored openh264) —
its first test call site anywhere. Config-latch seam guarded loudly.
Cross-crate mirrors recorded out of scope in the design doc:
session_plan::resolve_encoder, gamestream/serverinfo.rs
base_codec_mode_support, capture.rs's "pyrowave" string.

The ~410-line hand-mirrored AMF vtable ABI was already isolated in an
inline `mod sys` — the remaining value of the audit's 'best split in
the crate' is the FILE boundary: amf.rs drops 3379 → 2965 lines and the
pure unsafe-FFI surface (25 unsafe fns, zero policy) is reviewable in
isolation, which is the crate's stated review goal.
Pure move: `#[path = "amf_sys.rs"] mod sys;` keeps the module name and
every `sys::` call site byte-identical; the module was self-contained
(only `use std::ffi::c_void`, no super:: references). The banner became
the file's module docs; contents de-indented one level — rustfmt-clean
on the first check, which is what proves the move byte-exact.
Gated on .173: all five clippy combos + the amf-qsv,qsv test leg (38
passed — the live AMF matrix on real VCN silicon among them).

The two direct-NVENC backends carried hand-copied twins of the same
loss-recovery decision: range validity, covering-range dedup, DPB
window, clamp — ~30 duplicated lines each. The decision now lives once
as nvenc_core::plan_range_recovery (the range half of WP7.2; the slot
half is enc/rfi.rs), pure and unit-tested; each backend keeps its
session gate, its unsafe per-timestamp driver loop, and its state
stores.
The step order is load-bearing and now pinned by tests: the covering
dedup runs with the UNCLAMPED last and BEFORE the DPB window (a covered
re-ask never touches the driver even when the range has since aged out
of the DPB), the boundary at next_ts - RFI_DPB is inclusive, and the
Invalidate carries the CLAMPED last — which is also what the caller
records in last_rfi_range, exactly as the inline code stored it. A
driver failure mid-loop still returns false with NO range recorded and
no anchor armed. Decline deliberately clears nothing (neither twin
touched pending_anchor on decline — same shape as Vulkan's non-clear,
opposite of AMF/QSV; do not harmonize).
The exact-cover → Covered test records EXISTING behavior including that
a covered range survives a forced IDR with zero driver calls — a
recorded fact, not an endorsement. RFI_DPB's import leaves both twins:
its only per-backend use was the arithmetic that moved.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
AMF (user-LTR bitfield), QSV (mfxExtRefListCtrl) and Vulkan Video (the
app-owned DPB slot table) each hand-implemented the same loss-recovery
decision: distrust every reference encoded at-or-after the loss start,
anchor on the newest one strictly older. Three copies had already
diverged once — the fecbec2d taint sweep reached AMF/QSV a commit before
the Vulkan backend was carved out, and Vulkan shipped without it. The
decision now lives once in enc/rfi.rs, pure and unit-tested (this path
had zero coverage and is the loss-recovery path); every mechanism —
how a force is applied, how distrust is persisted — stays in its
backend.
Behavior-preservation notes, each critic-verified against the shipped
code:
- Callers feed only currently-trusted references; taint (>= loss) and
anchor (< loss) predicates are disjoint, so pre-sweep-view pick ==
post-sweep-table pick on every input. Tie-break preserved (first
entry wins == the strict '>' all three used, ascending slot order).
- plan_slot_recovery delegates its pick half to pick_anchor, which
keeps both items live on every leg (pick_anchor's only external
caller is Linux+vulkan-encode; dead_code is an item lint) and makes
'anchor chosen from the taint snapshot' structural.
- The decline arms are deliberately NOT uniform and stay put: AMF/QSV
clear an un-consumed pending_force; Vulkan leaves pending_loss armed
(a stale arm re-resolves at frame-build into the healing IDR) — now
pinned in comments on both sides.
- Vulkan's frame-build site is a pick-only re-run by design (the arm
carries the loss start, not the slot); pick_recovery_slot is deleted
and its tests migrated 1:1 into the shared module.
Test-count deltas are expected: the rfi tests now run on every Windows
combo (amf.rs is featureless there) and on the Linux feature leg.

A defaulted Encoder method that TrackedEncoder doesn't forward silently
no-ops through the wrapper — the host loop only ever holds the wrapped
box, so the feature dies for every session with nothing in the logs. The
trap has bitten three times (set_wire_chunking's §4.4 chunking probe,
set_pipelined's LN3 escalation, applied_bitrate_bps's ABR truth), and
every Phase 7 consolidation that adds a trait method re-arms it.
Source-text parse of the trait and the forwarding impl (both top-level
rustfmt items: block ends at the first column-0 brace, method names sit
on 'fn '-prefixed lines), then set equality — the reverse direction is
already a compile error, so equality == completeness. Mutation-verified:
removing set_wire_chunking's forward fails naming exactly that method.

The HDR/4:4:4 leg (188edde2, shipped 0.14.0) taught the client's plane
ring to allocate R16_UNORM on a 10-bit session, but the
pyrowave_image_view structs handed to decode_gpu_buffer kept the
original SDR shape: image_format/view_format hardcoded R8_UNORM, chroma
extents hardcoded half-res. pyrowave wraps our VkImage under the
DECLARED format and vkCreateImageView's its storage view from it
(pyrowave_c.cpp WrappedViewBuffers::wrap) — an R8 view over a
non-MUTABLE R16 image is invalid Vulkan that release drivers execute
anyway: the view's addressing covers half the surface, so the iDWT's
8-bit codes fuse pairwise into 16-bit texels (structured tile-scrambled
garbage) and the never-written remainder samples as all-plane zeros
(saturated green). Field report 2026-07-25: RX 9070 XT host → 780M
client, total corruption on every 10-bit PyroWave session regardless of
bitrate/refresh, wire counters spotless; milder shapes of the same UB
on NVIDIA clients; Arc validation never saw it because it ran SDR
(R8 ring — declaration consistent by accident).
Declare what the ring really built: format from hdr16 (R16/R8), chroma
extents from chroma444 (full-/half-res) — exactly what upstream's own
pyrowave_image_get_image_view fills from the image itself. Host
encoders audited clean: Windows keys plane formats off hdr16 already,
Linux is 8-bit end to end.
The tray led its tooltip with "⚠ conflicting host: Sunshine" and (on Linux)
went NeedsAttention for a Sunshine that was merely *installed* — never
started, never listening, harmless. An always-on warning over a dormant
package is a false alarm on every poll, and the tray is the wrong surface
for a one-shot install-time observation anyway.
Removes the `conflicts` field from the tray's `Summary`, the tooltip prefix,
`has_conflicts()`, and the ksni attention branch that fed on it. The host
still detects and reports conflicts where that belongs — the startup
`punktfunk::detect` warning, the `detect-conflicts` subcommand, and the
`/api/v1/local/summary` field, which the tray must (and does, per the new
test) keep tolerating on the wire.

WP4.5's device-selection half, closed as the observability intermediate after
TWO selection designs died in adversarial review:
- Attempt #1 (d26bcf05, withdrawn): match pf_gpu::selected_gpu(). Its Linux
auto arm answers "the NVIDIA GPU" whenever /dev/nvidiactl exists, moving
the encoder off the iGPU that can import the compositor's dmabufs on an
Intel-compositor + NVIDIA-present laptop — import failures feed the
process-wide raw-dmabuf latch, which never un-latches.
- Attempt #2 (this session, withdrawn before commit): anchor on the
PUNKTFUNK_RENDER_NODE-else-renderD128 node via VK_EXT_physical_device_drm.
Render minors are driver-BIND-ORDER artifacts, not display topology: on
the common AMD-iGPU + NVIDIA-display desktop, in-tree amdgpu binds before
out-of-tree nvidia, so the anchor deterministically picks the idle iGPU
while the compositor allocates on NVIDIA — the same latch, opposite
polarity, behind a success-looking log.
The correct oracle is evidence of which device ALLOCATED the capture
buffers — producer identity from the capture negotiation, threaded per
session into this open. Until that plumbing exists, selection stays
first-usable, both call sites still share one selector (pure over the
device list, so capture_modifiers and open_inner cannot diverge — including
across an in-place resize's re-open, which does not renegotiate capture),
and the open logs ONE greppable line: picked vendor/device, the anchor node
and its owner (DRM render major/minor, VK_EXT_pci_bus_info fallback), and
the console's selected GPU. A wrong-device session on a multi-GPU host used
to be completely invisible; a field report can now show it. No WARN arm on
purpose: the wrong-pick direction inverts between the laptop and desktop
topologies, so a mismatch is not evidence of a wrong pick, and a warning
that fires forever on healthy hosts teaches people to ignore warnings.
Decision recorded against the audit's framing: manual console GPU selection
stays unhonored by pyrowave on Linux (the Windows twin honors it) — honoring
console-mutable state without per-session threading is what made attempt #1
unsafe.
Verified on the 780M: the line resolves all three identities (1002:15bf x3,
DRM-props match live); full pyrowave on-glass suite green; selection
behaviour byte-for-byte unchanged.

Second attempt at WP6.3; the first (ce543668) was withdrawn after its tight
CBR window measured as a 36x bandwidth regression (97% filler NALs). The
correction that unlocked this one: that measurement's BASELINE row was an
8-frame artifact. Under the shipped 1000ms/500ms CBR window a calm stream
overflows the CPB once the initial fill drains (~30 frames at 10Mbps/60fps)
and RADV then pads every frame to the exact rate share, forever. Measured on
the 780M (1280x720@60, 10Mbps, calm content): 64 frames = 97.5% filler;
300 frames = 5.63MB at 98.5% filler where this commit ships 83KB at 0%.
AV1: 99.6% -> 0%. The status quo was ~the full target bitrate of zeros on
every idle AMD/Intel Vulkan-encode desktop and Steam Deck — and stuffing to
exactly the target permanently satisfied the ABR calm brake
(actual >= 3/4 * current), the ratchet WP6.3's withdrawal feared from the
tight window, live in the shipped code all along.
The fix reads VkVideoEncodeCapabilitiesKHR::rateControlModes (previously
ignored — rateControlMode was hardcoded CBR with no capability check) and
installs VBR with average == max plus the house ~1-frame window
(vbv_window_ms, PUNKTFUNK_VBV_FRAMES-scaled) when the driver advertises VBR.
VBR permits underspend, the exact missing degree of freedom: Vulkan exposes
no filler-suppression control (AMF's filler_data=false / NVENC's default-off
have no VK equivalent), so the MODE is the only lever. CBR-only drivers keep
the loose window untouched — tightening it under CBR just starts the stuffing
30 frames earlier. Drivers advertising neither mode (ANV per current Mesa)
keep the pre-existing CBR install, now WARN-logged.
No pacing claim, deliberately: burst A/B on the 780M is byte-identical
between 1000ms CBR and 17ms VBR (max AU 1.19MB in both) — this firmware
ignores the window for QP decisions entirely. The payload is filler
elimination. PUNKTFUNK_VULKAN_RC=cbr|vbr is the field escape hatch and the
on-box A/B control (two withdrawn attempts bought that insurance).
Also on the same caps struct: maxBitrate is now read and clamps open +
retarget (RADV reports 1 Gbps — within 5% of the 4K120 ABR targets), and
applied_bitrate_bps() reports the encoder-side truth (pending-first, so the
session loop's read right after reconfigure_bitrate sees the clamp) — without
it a binding clamp would feed the ABR a phantom base, the trap the trait doc
names.
And the one-frame VUID-vkCmdBeginVideoCodingKHR-pBeginInfo-08254 violation
found in the withdrawal review: record_submit promoted a pending retarget
into self.bitrate BEFORE recording whenever first_frame was set, so after a
mid-stream reset() (which preserves the pending rate and rc_installed) the
begin-coding declaration named a rate the session had not installed — and the
two triggers, ABR retarget and the stall watchdog, correlate. Now the
declaration always names the session's current rate and the RESET install
carries the pending one via its own struct; promotion stays in
post_submit_bookkeeping. The extended validation-layer test reproduces the
retarget-then-reset coincidence: exactly one 08254 on the pre-fix build, zero
on this one (RADV PHOENIX, on glass).
Gates: docker amd64 legs green; Windows .173 seven legs (34 passed);
.25 full-suite parity vs origin/main (identical CUDA-only failures) + all 9
vulkan on-glass tests + validation layers clean.

PyroWave never checked frame dimensions against the session, and it applies no
alignment — `width`/`height` are the negotiated mode verbatim — so a mismatched
frame was encoded edge-smeared or cropped, silently, forever.
Every other Linux backend already refuses exactly this, with this shape, in
`submit`: libav-NVENC (`linux/mod.rs`), VAAPI (`vaapi.rs`) and openh264 (`sw.rs`)
all carry the same `ensure!`. PyroWave was the only one that didn't. That is the
justification; an earlier draft cited `vulkan_video.rs` instead, which is the
weaker precedent — it bails in its Dmabuf arms only, and its CSC path and CPU arm
have no dimension guard at all.
Mostly this is a wrong-picture bug and not a memory-safety one: `rgb2yuv.comp`
clamps every fetch with `min(p, textureSize - 1)` and the CPU arm uploads
`min(len, need)` into a session-sized image. But it also closes a narrow real
hazard that was not in the filing: `import_cached` keys on `(st_dev, st_ino)` and
returns the cached `VkImage` on a hit WITHOUT rechecking the extent, and unlike
the capture side it is never cleared on a renegotiation — so a dmabuf inode
recycled across a shrinking renegotiation would hand the encoder an image sized
for the old, larger allocation. This check closes that route.
⚠ Recorded at the code because it changes the failure mode, not just the
detection: a mismatch is NOT always transient. A compositor-initiated PipeWire
renegotiation updates the capturer's size in place and signals nothing the encode
loop reads, so it can be a permanent new steady state — and `reset()` reopens at
the same dimensions by construction, so the host's five-reset budget cannot
recover (~3.1 s of frozen stream, then the session ends) where before it would
have streamed on with a wrong picture. For a real mode change that trade is
clearly right; for a 16-row KWin mismatch it is not, and the proper fix is for
the host to classify this error as a PIPELINE rebuild rather than an encoder
reset. Filed, not done here.
The device-selection half of WP4.5 was written, reviewed and WITHDRAWN — see the
handoff doc. Matching the selected render GPU regresses the hybrid
Intel-compositor + NVIDIA-present topology this project has a live field report
for, because `selected_gpu()` answers NVIDIA whenever `/dev/nvidiactl` exists
regardless of where capture actually runs.

The RGB-direct CPU-upload path allocated and zero-filled a whole padded frame on
every submit, filled it row by row, then memcpy'd the whole thing into the mapped
staging buffer. The zero-fill was entirely dead: the row loop writes every byte
of every row, and rows past the source re-copy the last source row. So the frame
paid for an allocation, a page-fault storm over fresh pages, a full zero-fill,
and two full-frame copies where one would do.
Map first, write the padded rows straight into the mapping. Nothing reads back
from the destination — the row source is always the caller's buffer, never the
staging memory — so writing into (write-combined) host memory costs nothing
extra, and `make_host_buffer` allocates HOST_COHERENT, so the writes need no
flush before the transfer reads them.
Measured on real RDNA3 780M silicon, release build, `submit` alone, 400 frames
x 3 rounds:
- **1920x1080** (rows padded to 1088): p50 2315 -> **1725 us** (-25%),
p99 2819 -> **1972 us** (-30%), and the spread (p99-min) tightens 739 -> 483 us.
- **1366x768 -> 1408x768** (BOTH axes padded, so the column tail loop runs):
p50 1013 -> **926 us** (-8%), p99 1303 -> **1110 us** (-15%). This is the one
case where the new code could have been slower — 4-byte stores straight into
write-combined memory — and it is not.
- **CONTROL, 1280x720** (64x16-aligned, so the branch is never entered):
p50 692 vs 692 us. No delta, which is what makes the two above attributable to
this change rather than to anything else on the branch.
The branch is reached by any RGB-direct session at a mode that is not 64x16
aligned, whenever capture delivers CPU frames (the default Linux capture path is
dmabuf and never enters it). 1080p qualifies, since 1080 aligns to 1088. ⚠ An
earlier draft of this message claimed "33 MB at 4K" — that is wrong: 3840 and
2160 are both already aligned, so 4K UHD never enters this branch at all. The
large case is an ultrawide like 3440x1440 -> 3456x1440, ~20 MB.
Three things this deliberately does NOT do:
- The extent guards stay scoped to the `pad` branch. The CSC path deliberately
supports a source SMALLER than the encode extent — its shader clamps at sample
time — so a guard hoisted above the branch would break it.
- Every fallible step stays above the map. An error raised between `map_memory`
and `unmap_memory` would strand the mapping for the life of the slot's staging
buffer, and the next frame's `map_memory` on it then violates
VUID-vkMapMemory-memory-00678. (The filed "two exits above the map leak Vulkan
objects" hazard is separately already gone: `47a23bec` moved that unwind into
`make_host_buffer`.)
- It adds guards rather than removing them: a zero source axis made `sh - 1`
underflow, and "cannot fail after the map" has to be true by construction.
Three corrections to an earlier draft, all found by review of that draft:
- The `dw*dh*4 == need` precondition was a `debug_assert!` placed BELOW the map.
That is wrong twice: it made the only check on the slice length vanish from the
builds that ship, and a fired assert would have unwound past `unmap_memory` —
the exact failure the bullet above says was designed out. It is now a real
checked `?` above the map.
- `need` was `(iw * ih * 4) as u64`: a u32 multiply widened after the fact, which
agreed with the usize slice length only up to ~32768x32768. The old code's
`min(need)` was a hard backstop against exactly that and the rewrite dropped
it. Now widened before the multiply, matching `read_slot`'s existing discipline.
- The extent guard now runs BEFORE the payload-length guard, so the usize
`sw * sh * 4` cannot overflow on a garbage frame header.

`std::env::var` was on three per-frame paths. Measured on `.173` (Windows, 57
environment variables, 2M iterations): **121.9 ns** per call for the NVENC
in-flight cap and **114.9 ns** per call for the ffmpeg poll spin, against
**0.9 ns** once memoized. On Linux, 32 ns → 1.5 ns.
⚠ Those numbers deflate the filing, and that is worth recording: the audit
ranked this as a hot-path defect, but ~120 ns/frame is ~0.003% of a frame
budget. The fix is still right — it is free, and it takes a global environment
lock off the encode thread — but nobody should schedule it ahead of anything on
the strength of the "hot path" framing.
The severity RANKING was also inverted, and the measurement confirms why. The
site the audit called worst — `nvenc_cuda`'s backpressure loop condition — costs
a default session nothing, because the condition short-circuits on
`async_rt.is_some()` and the default session never engages the two-thread
retrieve. The one that actually pays every frame is Windows `submit`, which
consults `async_inflight_cap()` in BOTH arms of the ring-depth match, sync mode
included, where the result is then thrown away. Windows `poll` is the second
unconditional one, and the audit ranked it last.
Memoized inside each helper rather than latched into a session field. Nothing in
the workspace mutates these variables at runtime (enumerated: no `set_var` for
either key anywhere in first-party code, and the Windows service's arbitrary-key
`host.env` loader runs in the SCM supervisor, which re-execs the host as a child
and never opens an encoder itself). A field would instead change WHEN the value
is read — and the Windows `cap` composes the env with `input_ring_depth`, which
`set_input_ring_depth` may change after open, so freezing that half would
reintroduce the in-place-overwrite bug the ring term exists to prevent.
Two deliberate behaviour changes ride along on `PUNKTFUNK_FFWIN_POLL_MS`, so
"behaviour-preserving" describes the memoization only, not this whole commit:
- **A 1000 ms ceiling.** The reachable hazard was never the overflow — that
needed `ms >= 1.8e16` — it was a slipped digit: `=100000000` was a 27.7-hour
spin of the encode thread.
- **`.trim()`, now on all three parsers.** An earlier draft applied the house
rule (WP7.8) to one of the three, which left `PUNKTFUNK_NVENC_ASYNC=" 1 "`
working while `PUNKTFUNK_NVENC_ASYNC_DEPTH=" 6 "` silently fell back to 4 —
and memoization would have frozen that silent fallback for the process
lifetime. Reachable: the Windows `host.env` loader trims around `=` before
stripping quotes, so `=" 2 "` yields a value with inner spaces.
⚠ Correction to an earlier draft of this message, which asserted that the audit's
`saturating_mul` proposal would relocate an overflow panic into release builds.
That is FALSE and the code comment now says so: `Duration::from_micros(u64::MAX)`
is ~1.8e13 seconds, six orders of magnitude below `Duration`'s ceiling, so
`Instant + Duration` neither overflows nor panics (measured, with and without
debug assertions). `saturating_mul` is still wrong, for a different reason — it
sets a deadline ~584,000 years out on a spin that provably never produces the
owed AU, i.e. it wedges the encode thread permanently. A hang, not a panic.
WP6.1.

`encodeCodecConfig` is a C union, so the `hevcConfig` writes in the 4:4:4 branch are only
meaningful on an HEVC session — on H.264 or AV1 they reinterpret that codec's own config bytes.
The branch was gated purely on `chroma_444 && full_chroma_input` with no codec test, and stayed
non-UB only because `lib.rs` degrades 4:4:4 for non-HEVC codecs: a two-file invariant with
nothing asserting it, on the path BOTH direct-NVENC backends take.
The audit filed that much. What it did not note is that the same shape hides a second bug:
this is an `if`/`else if`, so a non-HEVC session that arrived with `chroma_444` set took the
HEVC branch and skipped the per-codec bit-depth arm entirely — ending up with neither HEVC
4:4:4 (wrong for it) nor its own 10-bit configuration (simply absent). AV1 would have lost
`pixelBitDepthMinus8`/`inputPixelBitDepthMinus8` silently. Non-HEVC now falls through to the
arm that knows what to do with it, and an unexpected request is logged rather than swallowed.
Adds two tests that need no GPU — `apply_low_latency_config` is pure config authoring, so an
AV1 session can assert it never receives the HEVC FREXT profile GUID (an INVALID_PARAM at
open) and that its own depth still lands, with an HEVC case guarding the good path.
⚠ `NV_ENC_CONFIG` must NOT be `mem::zeroed` in those tests: `frameFieldMode`/`mvPrecision` are
C enums whose discriminants start at 1, so all-zero is not a valid value and Rust's zero-init
check ABORTS the process (SIGABRT, caught by the Linux gate). They seed it from `Default` the
same way `build_config` does before overwriting from the driver preset. Worth knowing before
writing any further test against these SDK types.
Verified: Linux gate L1-L4 green (39 tests, the two new ones among them) and the full Windows
gate on .173 — 7 legs. Note the Windows test leg runs `--features qsv`, so these tests only
execute on the Linux leg; the Windows legs prove the change compiles in all five feature
combinations.
`ir_active` was `cfg.intra_refresh && set.co2.is_some()` — i.e. "we asked for it", not "we got
it". Both `Query` and `Init` can return MFX_WRN_INCOMPATIBLE_VIDEO_PARAM, a WARNING the open
path deliberately accepts, while dropping the intra-refresh wave on the floor.
That lie is not cosmetic. `ir_active` feeds `EncoderCaps::intra_refresh`, so the session
advertises gradual refresh to the client; the client then stops asking for the IDRs it would
otherwise request on packet loss, and a lost frame gets concealed instead of repaired. The
stream degrades exactly when recovery matters.
Now confirmed against the driver: a best-effort `GetVideoParam` with a CodingOption2 buffer
chained on, read back for `IntRefType`. Deliberately a SEPARATE query rather than a buffer
attached to the existing `BufferSizeInKB` call (which is what the audit finding suggested) —
that value backs every bitstream allocation, and a runtime that disliked the chained buffer
would take it down with the readback. A failure here costs only the verdict and resolves
conservatively (trust the request), so the worst case is the previous behaviour.
Verified on Intel UHD 750 (.42), which is where the Intel on-glass run originally caught this:
with PUNKTFUNK_INTRA_REFRESH=1, H.264 now logs "silently dropped intra-refresh
(GetVideoParam reports IntRefType=0)" and advertises it OFF, while H.265 on the same GPU
stays ON — it is genuinely active there. Per-codec, so it could never have been decided
statically. 8 live QSV tests pass.
Gated on .173: clippy -D warnings at nvenc,amf-qsv,qsv (host + pf-encode --all-targets),
amf-qsv without qsv, qsv alone, no-features, cargo test --features qsv, rustfmt — all green.
qsv.rs is Windows-only so the Linux legs do not compile it.
Closes WP3.2(c), the last Phase 3 item that was hardware-blocked.
Phase 5's Linux half (audit WP5.1 + WP5.4), each item shaped by the
review that rejected the obvious fix:
Dmabuf import unwind (vk_util): every failure after create_image leaked
the VkImage, and the dup'd dmabuf fd leaked as a raw i32. The sharp edge
is that a SUCCESSFUL vkAllocateMemory transfers fd ownership to Vulkan
(vkFreeMemory closes it), so the naive close-on-error is a double close
that clobbers whatever unrelated descriptor recycled the number. The dup
now lives in an OwnedFd released exactly in the allocate-success arm;
every other path drops it once, and bind/view failures free image+memory.
PyroWave open unwind: open_inner had ~20 fallible steps that each leaked
everything before them (instance, device, pyrowave objects, the whole
CSC pipeline). Rather than a parallel teardown guard — whose reviewed
hazards were a null-unsafe pyrowave_encoder_destroy and a drifting
duplicate of Drop — Self is now constructed right after create_device
with every later resource null, and the existing Drop (wait-idle first,
pw_enc null-guarded, delete-nullptr and VK_NULL_HANDLE destroys are
no-ops) is the single unwind path for error and normal teardown alike.
The ensure_cpu_rgb staging twins (create/allocate/bind, both backends)
and the RGB-direct make_view pair get the same discipline via a shared
make_host_buffer. Observed on hardware: 32 forced import failures, zero
fd drift (the new import_failure_leaks_no_fds smoke on RADV).
24-bpp CPU service (WP5.4): pixel_to_vk had no mapping for the packed
Rgb/Bgr the PipeWire portal negotiates, so a session committed to a path
the backend could not serve and died at its first frame. The filed
open-gate was rejected as a half-mirror — the dmabuf axis is keyed by
fourcc at submit, unknowable at open — so instead the CPU axis is
SERVED: a 3-to-4 expand at the staging upload (normalize_cpu_rgb, the
CPU twin of WP1.4's swscale expand), order-preserving for the CSC
samplers and BGRA-forced for the RGB-direct encode source, whose session
pictureFormat is B8G8R8A8 — the on-glass run caught R-first sources
violating VUID-vkCmdEncodeVideoKHR-pEncodeInfo-08207, a mismatch that
predates this change for plain Rgbx CPU sources. The dmabuf axis feeds
pf-zerocopy's raw-dmabuf degrade latch (3efbe416) from both Vulkan
import caches — deterministic refusals flip capture to CPU delivery,
which now serves every format capture produces; transient OOM and
native-NV12 sessions are excluded.
RECORDING-state hygiene: the fallible recording prefix (cursor prep,
import, staging) now resets the command buffer on error instead of
leaving it RECORDING for the next begin to trip
VUID-vkBeginCommandBuffer-commandBuffer-00049; PyroWave's submit-level
blanket reset is replaced by the same scoped shape, closing its
fence-timeout hole where a reset hit a PENDING buffer
(VUID-vkResetCommandBuffer-commandBuffer-00045).
Verified: docker linux/amd64 4-leg gate green; RADV 780M on-glass under
the validation layers at 1920x1080 — all 10 smokes pass (including the
new 24-bpp CSC + RGB-direct legs and both channel orders), decoded
colour truth checked with ffmpeg, and the only remaining validation
messages are the two documented VALVE-extension layer gaps plus a
pre-existing pyrowave shader/feature mismatch now filed in the planning
doc.

import_plane closed the shared NT handle on every pyrowave_image_create
failure, believing pyrowave only consumes it on success. The vendored
truth was messier: Granite's allocator closed by-reference handles
UNCONDITIONALLY after the first vkAllocateMemory — success AND failure —
while failures before the allocator (validation, vkCreateImage, no
memory type) left the handle open, and both classes surface as the same
error code. So the call site could not know whether to close, and an
allocate-stage failure double-closed a possibly-recycled handle value
(audit WP5.3). The filed fix (DuplicateHandle + close the original
unconditionally) traded the double close for a guaranteed leak on every
pre-allocate failure and left the ambiguity in place.
Patch 0006 fixes the callee instead: the allocator never closes a
caller's handle, and pyrowave_image_create consumes it exactly at its
success return — which is what pyrowave.h ("take ownership and close the
HANDLE on import") documents, and what Granite's semaphore import
already did, so import_fence was correct as written and the two paths
now share one contract. The close-on-failure in import_plane is thereby
correct on EVERY path, including a vkBindImageMemory failure after a
successful allocate. Bonus fix recorded in the patch: the allocator's
block-recycling retry loop used to re-run vkAllocateMemory with
import_info still pointing at the just-closed handle.
Both-platform gates green; pyrowave_win_smoke (.173, 34/34) re-validates
the live import path against the rebuilt vendored C++.

Three Windows NVENC teardown/accounting defects (audit WP5.2, marked
BLOCKING — the obvious fixes were reviewed and rejected before this):
Event-handle leak: init_session pushed each completion event to
self.events only AFTER nvEncRegisterAsyncEvent, so a failed registration
leaked the Win32 handle. Push first — the init-failure path already runs
teardown, which closes everything in the list (unregistering the one
never-registered event is a harmless error return).
Wedged drain: teardown drains the retrieve thread's backlog, and each
queued job could burn its full 5 s completion wait — cap x 5 s on the
encode thread, paid again on every rebuild of the stall-recovery ladder.
The rejected fix (a shutdown flag) abandoned the backlog on EVERY
teardown, turning the routine drain into destroy-while-encoding. Instead
the wedge evidence stays where it lives: after one full-budget timeout in
the retrieve loop, later jobs wait a 250 ms slice; a success resets the
latch. Routine teardown is byte-identical to before — nothing is ever
abandoned — and a first timeout is already encoder-fatal, so short
slices behind an established wedge change only how long teardown blocks.
Session-unit accounting: LIVE_SESSION_UNITS was refunded even when
destroy_encoder FAILED, drifting the budget low and over-admitting
parallel displays. The rejected fix (never refund on failure) let one
transient wedge episode poison admission until a host restart. Now the
refund follows PROOF: destroy succeeded, or its status says the driver
holds no session (device gone/TDR). Ambiguous failures park the handle —
units still charged, fail-closed, pinning the D3D11 device the driver
session references — and init_session retries the destroy while zero
sessions are live, under a gate that serializes every session open
against the reap so a recycled handle address can never alias a live
session. The charge lasts exactly as long as the driver keeps refusing
the destroy, which is the definition of still-leaked. Admission stays a
lock-free atomic load.
Both-platform gates green (docker linux/amd64 4 legs; .173 all 7 legs).
The retry-destroy-on-a-failed-handle assumption is documented at the
reap: the SDK defines no retry semantics either way.

A dmabuf import the GPU driver refuses is refused identically on every
retry, but the only recovery above it was the encode-stall ladder: five
in-place encoder rebuilds, then the video session ends. So a host whose
driver will not take what its compositor allocates lost every session
on its first frame, and every reconnect repeated it — while the very
same host streamed fine with `PUNKTFUNK_ZEROCOPY=0`. The software knew
how to run that machine and never chose to.
Latch it, exactly as the sibling CUDA-import path already does after
repeated worker deaths: three consecutive import failures with no frame
in between disable the raw-dmabuf passthrough for the host process, and
capture negotiates CPU frames from the next session on. Three sits
below the encoder's rebuild budget, so the latch is set before the
session it doomed ends — one bad session, then a working (if slower)
host, with a log line saying which and why instead of an operator
having to find an environment variable.
Only the two stages that ARE the import are counted — the buffersrc
push of the DRM-PRIME descriptor and the buffersink pull where `hwmap`
maps it into a VA surface. `avcodec_send_frame` is deliberately left
out: that one is the encoder stalling, which the in-place rebuild
exists to recover, and taking zero-copy away permanently over a
transient fault would be a bad trade.
The latch lives in pf-zerocopy because it is the leaf both sides can
see — the capture→encode edge is one-way by design, so pf-capture
cannot ask pf-encode anything.
The zero-copy DRM-PRIME descriptor declared `objects[0].size = 0`, on
the belief that ffmpeg would work the real size out. It does not: both
of its import paths pass the value straight through to libva —
`prime_desc.objects[i].size` on the PRIME_2 path, `buffer_desc.data_size`
on the legacy fallback it tries next — so every VA driver we have ever
handed a dmabuf to was told the backing object was empty and left to
derive the size itself.
The drivers this path has run on (radeonsi, modern Intel iHD) derive it
correctly, which is why nobody noticed. A Gen9 Intel host does not get
that far: `vaCreateSurfaces` answers VA_STATUS_ERROR_ALLOCATION_FAILED
on the first frame and every frame after it, `av_buffersink_get_frame`
returns EIO, and five in-place encoder rebuilds later the video session
is over. That host cannot stream at all with zero-copy on.
`lseek(SEEK_END)` is the standard dma-buf size query and the same one
this tree's Vulkan bridge already performs on these very fds. A kernel
that refuses it leaves the old 0 rather than costing a frame that might
still have encoded.
Whether this alone fixes that host is unconfirmed — the descriptor was
wrong either way, and it is the first thing the driver reads.
The EGL importer — the head of the CUDA/NVENC zero-copy path — opened
`/dev/dri/renderD128` and hoped. On a single-GPU host that is the
NVIDIA node and it always worked. On a hybrid laptop the iGPU is bound
first, so renderD128 is Intel: we built a GBM device on Mesa, asked it
for a pbuffer-capable OpenGL config, got none (Mesa's GBM platform
advertises only window-capable ones — gbm_surface is the point of that
platform there), and reported
zerocopy worker init failed: no EGL config for OpenGL
on a machine whose NVIDIA EGL stack was demonstrably fine, naming
neither the device nor the reason. `PUNKTFUNK_RENDER_NODE` was no
escape either: this path never read it.
Pick the node by what it is — the first `/dev/dri/renderD*` whose
sysfs PCI vendor is 0x10de, the same identification the crate's Vulkan
bridge already uses for its physical device. A local scan rather than a
`pf_gpu` dependency, because this crate is a leaf whose worker is its
own process, and `pf_gpu::linux_render_node` answers a different
question anyway: it follows the operator's GPU *preference*, which may
legitimately name the iGPU. What is needed here is not which GPU to use
but where CUDA is. `PUNKTFUNK_ZEROCOPY_RENDER_NODE` overrides, and no
NVIDIA node found keeps the historical guess — sysfs may just not be
mounted, and the CUDA context is what properly fails on a host with no
NVIDIA at all.
Then stop the config query being able to fail this way: retry without
the surface-type constraint, which is honest because we never create an
EGLSurface — `eglMakeCurrent` runs surfaceless. And name the node in
every error and in the ready line, so the next hybrid host diagnoses
itself.
`punktfunk-scripting` with nothing to run pinned a full CPU core
indefinitely — in exactly the state its own systemd unit documents as
inert ("the runner does nothing until you add scripts or install
plugins"). A field report on a 7.7 GB laptop had it at 99.9% CPU for
two hours straight, `strace` showing a bare `clock_gettime` loop and no
other syscall at all, which starved the compositor badly enough to
blank the physical display.
Nothing in the runner was looping. `Effect.runFork` registers nothing
with the event loop — effect's keep-alive timer lives in
`Runtime.makeRunMain`, which runner-cli deliberately doesn't use
because its shutdown is the bespoke two-signal one — and a bun process
whose only pending work is an unresolved promise busy-spins rather than
blocking. With units running there is normally a socket or timer to
park on; with none there is nothing at all, so the no-op state was the
one state that span.
Hold one idle handle for the runner's lifetime and drop it when the
unit tree ends on its own. Measured on the packaged bun (1.3.14), three
seconds idle with empty scripts/plugins dirs: 3098 ms of CPU before,
280 ms after (bun's startup, then nothing).
The regression is a property of the process rather than of any function
in it, so the test spawns the real CLI and reads the child's CPU time,
asserting it also logged and stayed alive — a crashed runner burns no
CPU either and must not pass.
Found by running the smokes at 1920x1080 under the validation layers while chasing the three
items left over from WP4.2. AV1 forbids the encode source's `codedExtent` differing from the
sequence header without `FRAME_SIZE_OVERRIDE`
(VUID-vkCmdEncodeVideoKHR-flags-10324), or from the reference slots without
`MOTION_VECTOR_SCALING` (`-10325`). RADV PHOENIX advertises NEITHER — and RGB-direct is the
default on EFC hosts with true-extent the default at unaligned modes, so plain 1080p AV1 was
tripping both on every frame: source 1920x1080 against an app-aligned 1920x1088 header and
DPB. Measured 16 violations per 8-frame run; the CSC path had none.
The fix is to make all three agree at the RENDER size rather than the aligned one — an
unpadded coded size is valid on this hardware, so the coded frame simply IS the visible
frame:
- the AV1 sequence header follows the render size when true-extent is active (joining
native NV12, which already authors true-size headers for the same reason);
- the DPB setup and reference slots carry `src_extent` instead of the aligned `ext2d`.
`src_extent` already collapses to `ext2d` whenever true-extent is off, so every other
configuration is untouched;
- `render_and_frame_size_different` now compares render against the DECLARED source extent
instead of the aligned size, or true-extent would have claimed a mismatch that no longer
exists.
Fixing only the header is not enough and is actively misleading: it clears -10324 and
immediately exposes -10325, because the mismatch has moved to the reference slots rather than
gone. Both had to move together.
This keeps the EFC fast path. Two alternatives were implemented, measured and rejected on the
way here: falling back to the compute CSC costs the zero-copy the B2 work existed to deliver,
and routing to the padded-copy staging trades these two VUIDs for
VUID-VkImageCreateInfo-pNext-06811 — `pad_img`'s extra TRANSFER_SRC usage is not in the
profile-advertised set, measured 8x per session on HEVC-padded too, so that is a pre-existing
defect of the padded path and not somewhere to route a default session.
HEVC is deliberately untouched: it has no equivalent constraint (its crop rides the
conformance window), it measures zero violations, and its aligned-SPS path is the validated
one.
On RADV PHOENIX (780M, Mesa 26.0.4) the AV1 stream now decodes as coded 1920x1080 / render
1920x1080 — genuinely unpadded, where before the alignment rows were encoded and cropped
back out. The CSC path still reports coded 1920x1088 / render 1920x1080, which is correct for
it. All four `vulkan_smoke*` pass at 256x256 and 1920x1080.
Two validation errors remain on the RGB-direct path and are NOT ours, now with evidence
rather than assumption: `VUID-VkImageViewCreateInfo-image-08336` uses the PROFILE-BLIND format
query, so it cannot see that RGB conversion legalises BGRA as an encode source — the
profile-aware query used by -06811 accepts the very same image; and
`VUID-VkQueryPoolCreateInfo-pNext-pNext` rejects
`VkVideoEncodeProfileRgbConversionInfoVALVE`, which the VALVE extension REQUIRES for profile
identity, and the layer diagnoses itself as "a struct from an extension added to a later
version of the Vulkan header".
Verified: canonical Linux gate (docker linux/amd64) L1-L4 green; on-glass on RADV PHOENIX

WP4.1 — Windows NVENC sticky state. Both halves were the same mistake: a single field doing
duty as both "what the session negotiated" and "what this session can actually do", so the
first downgrade destroyed the negotiation.
- `query_caps` clears `self.hdr` on a GPU without 10-bit encode, but `submit` re-derives the
requested HDR state from every frame's pixel format and compared it against that cleared
value. On such a GPU a P010 capturer therefore reported "HDR changed" on EVERY FRAME and
tore down and rebuilt the whole encode session each time. The trigger now compares against
`hdr_requested`, and the downgrade is latched in `hdr_unsupported` so it is remembered
(and warned once) instead of rediscovered per init.
- One subsampled-YUV frame cleared `chroma_444` permanently, so 4:4:4 never returned when
the capturer went back to RGB. The negotiation now lives in `chroma_444_requested` and the
effective value is recomputed at every init; the per-session downgrade still happens and
is still reported honestly through `caps()`, it just is not destructive any more.
WP4.3(a) — QSV HDR mastering luminance was divided by 10,000. The old comment justified it as
"VPL wants whole cd/m²", which is true of the VIDEO-PROCESSING unit but not the encode path:
the runtime passes the value straight into the ITU-T H.265 Annex D mastering-display SEI,
whose unit is 0.0001 cd/m². Verified end to end on Intel UHD 750 by dumping the bitstream and
reading SEI 137 with trace_headers, before and after:
before: max_display_mastering_luminance = 1000 (0.1 nits)
after: max_display_mastering_luminance = 10000000 (1000 nits)
with `min` (500 = 0.05 nits) and both content-light-level fields unchanged. That asymmetry —
a correct min beside a 10,000x-low max — was the original tell.
WP4.3(b) — `reconfigure_bitrate` never re-read `BufferSizeInKB`, so an ABR step-up could hand
the runtime an AU buffer sized for the old, lower bitrate. Fixed in both places it was broken:
re-read the driver's answer via `GetVideoParam` after the `Reset` (mirroring `init_encode`),
AND stop `take_bs` recycling pooled buffers without checking their capacity — the pool would
otherwise keep serving short buffers even once `bs_bytes` was correct.
WP7.8 — the `PUNKTFUNK_QSV_FFMPEG` half, finally landable now that a Windows gate exists (it
sits behind `#[cfg(feature = "qsv")]`, so nothing in a Linux-only matrix compiles it — it was
deliberately held back for exactly that reason). Trimmed like its siblings, and kept
case-insensitive: the knob already accepted `TRUE`, and the bare house `matches!` would have
silently dropped that spelling.
Phase 4 of the audit is now complete, and WP7.8 with it.
Verified: Windows gate on .173 — clippy -D warnings at nvenc,amf-qsv,qsv (host + pf-encode
--all-targets), amf-qsv without qsv, qsv alone, no-features, `cargo test --features qsv`
(34 passed), rustfmt. Linux docker gate L1-L4 green. On-glass: the QSV A/B above on .42.
Owed: NVENC sticky-state on-glass on .173 (needs a live 10-bit-capable capture toggle).
WP4.2 of the pf-encode audit, validated on RADV PHOENIX (780M, Mesa 26.0.4) under the Vulkan
validation layers rather than by inspection alone. Three of the five reproduce with the
driver naming the violation; one turned out milder than filed and is recorded as such.
1. `ensure_cpu_rgb` cached the staging image on FORMAT ONLY while sizing it to the SOURCE
frame, and the copy uses the CURRENT frame's extent — so a same-format source-size
increase copied past the allocation. Now keyed on (format, width, height). This is the
memory-safety one: on hardware it was 8 x
VUID-vkCmdCopyBufferToImage-imageSubresource-07971 ("extent.width (512) exceeds
imageSubresource width extent (128)") and `submit` returned Ok every single time, so
nothing upstream could notice. Zero after the fix. Note the trigger for anyone re-testing:
the image is cached PER RING SLOT, so the ring must wrap before a slot sees a larger frame
— two differently-sized submits in a row land on different slots and look fine.
2. The RGB-direct CPU padding loop only ever grows a source into the aligned extent; a source
LARGER than the encode extent panicked on the row `copy_from_slice`. Now refused by name,
matching what the DMA-BUF arms already do, so a bad frame takes the encoder-rebuild path
instead of unwinding out of the encode thread with an index message.
3. AV1 wrote `render_width/height_minus_1` but never set
`render_and_frame_size_different`, and AV1 ignores the render size unless that flag says it
differs — so every mode needing 64x16 alignment presented the padding. libdav1d on the
encoded stream now reports `size 1920x1088 ... render 1920x1080`; before, the flag being
unset meant render defaulted to the coded 1088, i.e. 8 rows of duplicated edge pixels
shipped to the client.
4. `read_slot` read the PERF timestamp pool whenever the pool merely EXISTED, but the
padded-RGB path's CPU-upload arm records its own command buffer and writes no timestamps —
reading an unreset query with WAIT is undefined. Now gated on a per-slot `ts_written`,
because "a pool exists" was being used as proof of "the pool was written". SEVERITY
CORRECTION vs the audit: this is not a hang in practice. It needs PUNKTFUNK_PERF *and*
RGB-direct *and* the non-default PUNKTFUNK_VULKAN_RGB_TRUE_EXTENT=0 *and* an unaligned mode
*and* CPU capture, and RADV then fails the read rather than blocking. Another driver may
block, hence the fix.
5. `reset()` re-arms `first_frame`, which was also what decided whether begin-video-coding
declares the rate-control state. But a reset does not rebuild the session, so the CBR
installed earlier is still current when the next frame opens its coding scope: the
declaration was omitted exactly when it was required. Split into `rc_installed`, which
survives reset. On hardware this was
VUID-vkCmdBeginVideoCodingKHR-pBeginInfo-08253 ("no VkVideoEncodeRateControlInfoKHR ... but
the currently set mode is CBR"); zero after.
Also fixes two pre-existing AV1 spec violations that were firing on EVERY frame of a shipped
path and are not in the audit at all — found only because the validation layers were on, and
confirmed untouched by this branch before being attributed as pre-existing:
`constantQIndex` must be 0 unless rate control is DISABLED (VUID-...-10320; this session is
always CBR, so the driver owns Q), and `pStdPictureInfo->pSegmentation` must be NULL
(VUID-...-10350; it pointed at a zeroed struct, and leaving it unset means the same
"segmentation disabled" while being spec-correct).
Items 1 and 5 keep their reproductions as `#[ignore]`d hardware tests, documented as
meaningful only under `VK_LOADER_LAYERS_ENABLE='*validation*'` since the violations are
invisible to the API's return values.
STILL OPEN, filed not fixed (three more pre-existing validation errors the cleanup exposed):
VUID-VkQueryPoolCreateInfo-pNext-pNext on the AV1 and RGB paths, and 2 x
VUID-VkImageViewCreateInfo-image-08336 (the RGB-direct encode-src view's format features lack
VIDEO_ENCODE_INPUT) — the latter may be a validation-layer gap around the VALVE extension
rather than our bug, and wants real analysis rather than a quick patch.
Verified: canonical Linux gate (docker linux/amd64) fmt + clippy --all-targets at default and
at nvenc,vulkan-encode,pyrowave + both test legs; and on RADV PHOENIX all four `vulkan_smoke*`
tests pass at 256x256 and at 1920x1080 with zero validation errors on the paths touched here.
Both come straight out of the first compositor-less bring-up (P3), on a
two-GPU box:
PUNKTFUNK_DRM_CARD=<n> pins SDL's KMSDRM device index. SDL enumerates
/dev/dri/card* and takes the first it can open, which is regularly the
wrong one: it chose the card a live compositor already held DRM master on
and died at swapchain creation, while the idle card with the connected
display sat unused. Kept an explicit operator choice rather than
auto-detection — deciding "is this card already mastered" needs the very
ioctl that taking master IS, so any in-process guess would be fragile.
The swapchain error now carries what to actually check. "vkCreateSwapchainKHR:
Initialization of an object has failed" is useless to someone bringing up a
kiosk; on the kmsdrm backend it now names the pinned card and lists the
three real causes in order (no connected connector / another DRM master /
NVIDIA). Empty on every other backend, where it would be noise.
The NVIDIA note is measured, not guessed: on NVIDIA proprietary + kmsdrm,
Vulkan enumerates the GPU AND the display (VK_KHR_display reports the
connected HDMI connector) and still fails — as root, with
nvidia_drm.modeset=Y, on a card no compositor was using. Not permissions,
not DRM master; their direct-display path wants the display leased via
vkAcquireDrmDisplayEXT and SDL's kmsdrm surface path does not do that.

Two things were x86-specific, both now expressed properly instead of
hardcoded:
* PKG_CONFIG_PATH carries the runtime's multiarch directory.
flatpak-builder does NOT shell-expand `env` values, so ${FLATPAK_ARCH}
would be taken literally — a build-options.arch override supplies the
aarch64 string and inherits the rest.
* The prebuilt Skia archive is per-target and pinned by sha256. Two
`type: file` sources discriminated by only-arches now share one
dest-filename, so SKIA_BINARIES_URL stays a single literal path.
Upstream publishes the aarch64 archive under the same skia commit hash
and the same resolved-feature key, so the two stay in lockstep on a
skia-safe bump.
build-flatpak.sh gains ARCH (default: this machine's), passes --arch to
both flatpak-builder and build-bundle, and arch-suffixes the bundle name so
an x86_64 and an aarch64 build can coexist in dist/ instead of the second
silently overwriting the first. CI composes its own published filename, so
nothing downstream changes.
The aarch64 Skia sha256 was verified by downloading the published archive,
not taken from the API. No aarch64 flatpak has been built — flatpak-builder
builds in a sandbox for the target arch, which needs an arm64 machine.

arch=('x86_64' 'aarch64'), and on aarch64 `pkgname` drops punktfunk-host
so makepkg never enters the host's build or package path; build() takes a
client-only cargo invocation without the NVENC/Vulkan-encode features.
Dropping the host from pkgname rather than giving package_punktfunk-host a
per-package arch is what makes the skip unambiguous, and it mirrors how
PF_WITH_WEB already extends that array.
The host stays x86-only because its encode stack (NVENC/QSV/AMF) is.
Verified by sourcing the PKGBUILD under both CARCH values: x86_64 yields
`punktfunk-host punktfunk-client`, aarch64 yields `punktfunk-client`. NOT
verified by a real build — there is no official arm64 Arch container, and
the README says so rather than implying it is tested.

The blocker was never ExclusiveArch — it was that %build builds host +
tray + client together and %install lays down the host unconditionally,
with no way to express "client only". `%bcond_without host` (default ON,
so an x86_64 build is unchanged) now gates the host binary, the tray, the
headless-session data, the firewalld services, the main %post and the bare
%files section. Omitting %files for the MAIN package is the load-bearing
part: it is what stops rpm emitting an empty `punktfunk` alongside
punktfunk-client.
build-rpm.sh exposes it as PF_WITHOUT_HOST=1 and skips the libcuda stub
regeneration and the libcuda leak check, neither of which means anything
without the host.
Verified two ways. `rpmspec -P` shows the default expansion still carrying
3 host install lines, the tray build and one bare %files, while
--without host carries none of those and one %files client. And a real
rpmbuild in a native aarch64 Fedora 43 container produced
punktfunk-client-*.aarch64.rpm with correct aarch64 sonames
(libc.so.6(GLIBC_2.17), libSDL3.so.0, libavcodec.so.61) and no main
package.
Not a cross-compile: %build runs cargo for the build machine's arch, so
this wants an arm64 builder. No CI leg yet — deliberate.

Adds a `rust-arm64` job: clippy -D warnings for the client crates at
--target aarch64-unknown-linux-gnu, plus a --no-default-features session
build so the minimal embedded configuration keeps compiling in its own
right rather than only as a subset of the default one. Runs in the cross
image on the ordinary amd64 runner; client crates are listed explicitly
because --workspace would drag in the x86-only host encode stack.
This is a regression guard, not an artifact leg (deb.yml ships those).
c_char signedness cuts both ways and neither direction is visible from an
x86-only CI: hardcoding i8 fails to COMPILE on ARM, while casting to u8
fails the LINT on ARM. Two such defects were already found this way.
Also documents the arm64 client .deb recipe in packaging/debian/README.md.

`c_char` is i8 on x86_64 and u8 on aarch64, so `cert_pem_out as *mut u8`
is a REQUIRED conversion on one target and a no-op on the other — where
clippy::unnecessary_cast then denies it. `.cast::<u8>()` is correct and
lint-clean on both.
Caught by the new aarch64 clippy leg on its first run. A sweep of the
remaining `as *mut u8` / `as *const u8` sites in the client crates found no
other c_char-derived casts; the rest convert from c_void or u16.

Adds punktfunk-rust-ci-arm64cross (the rust-ci toolchain + an Ubuntu ports
arm64 multiarch sysroot) and a deb.yml job that cross-builds the client
package on the ordinary amd64 runner — no arm64 runner in the fleet and
none needed. Client only: the Linux host encodes with NVENC/QSV/AMF, all
x86. The apt registry keys pool entries by the .deb's own arch, so an arm64
box picks the package up with no client-side configuration.
Three things this had to get right, each of which cost a failed build:
* rustup target add must run against the toolchain rust-toolchain.toml
PINS, not the image's default `stable` — otherwise the pinned toolchain
has no aarch64 std and the build dies ~230 crates in on "can't find
crate for core". Copying the pin file in also pre-downloads the
toolchain every CI job currently re-fetches on first use.
* ffmpeg-sys-next compiles a probe it intends to RUN, so it forces
.target(HOST) while still passing the TARGET's include paths; the arm64
dir then shadows the host's own libc headers and the x86 compiler dies
in bits/math-vector.h on NEON/SVE types. Prepending the host dir does
NOT help — GCC drops a -I that duplicates a system directory, keeping
its original later position — so ci/pf-host-cc strips target include
dirs from host compiles instead.
* the job hard-fails on a non-AArch64 session binary, rather than
shipping an amd64 payload under an arm64 package name.
skia needs no special handling: the aarch64-linux-gnu textlayout+vulkan
prebuilt resolves, so arm64 ships the FULL client, OSD included — unlike
Windows ARM64, which still builds --no-default-features.
The cross image builds in its own docker.yml job (needs: build-push) since
it is FROM punktfunk-rust-ci:latest and must not race the entry that
publishes that base. rpm/Arch/Flatpak stay x86_64 for now — their builders
have no arm64 sysroot, which is its own piece of work.

`punktfunk-session --pair <PIN> --connect host[:port]` runs the SPAKE2
ceremony with no window and no toolkit, prints the same
`paired <addr>:<port> fp=<hex>` line as `punktfunk-client --pair`, and
exits. Until now the PIN ceremony lived only in the GTK shell or the Skia
console, so enrolling an embedded/kiosk client meant installing a desktop
on it — or copying the identity store by hand.
Dispatches above every graphics call (the machine may have no display) and
is in the `--no-default-features` build: enrolling must never be the reason
a minimal image pulls in Skia. `--name` defaults to the hostname instead of
the desktop path's hardcoded "Steam Deck".
`forget_placeholder` and `device_name` move into pf_client_core::trust so
the two binaries share one implementation rather than the session
re-deriving them.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
`char` is signed on x86_64 but UNSIGNED on aarch64, so the hardcoded
`Vec<*const i8>` compiles on every desktop target and then fails to match
ash's `&[*const c_char]` when cross-compiling the client for ARM.
Found by the aarch64 cross-build spike (punktfunk-planning:
embedded-arm64-client.md) — the only portability defect in the client
stack; nothing else in the client crates assumes an architecture.

openh264 tops out at level 5.2 — 3840x2160 landscape or 2160x3840 portrait — and enforces
that ceiling inside `reinit`, which the crate calls on the FIRST ENCODE rather than at
encoder construction. So an oversized mode built a perfectly healthy-looking encoder and
then failed every single submit: the session connects, negotiates, and never delivers a
frame, with the real reason buried in a per-frame error rather than at the open.
`validate_dimensions` does not cover this. It is keyed on the codec, and H.264 legitimately
reaches 4096 on every hardware backend — this ceiling belongs to the software backend alone,
which is exactly the path a GPU-less host falls back to.
Rejects at open instead, mirroring the rule from the openh264 version we actually ship
(0.9.3) rather than from its docs — including the orientation-aware shape, since a naive
per-axis `w <= 3840 && h <= 2160` would wrongly refuse a legal 2160x3840 portrait session.
Three tests: the accepted modes in both orientations, the modes `validate_dimensions` lets
through but openh264 cannot serve, and that `open` itself refuses rather than deferring to
submit. They cost nothing to run — the guard fires before openh264 is initialised at all.
Verified with the canonical Linux gate (docker linux/amd64): fmt, clippy --all-targets at
default and at nvenc,vulkan-encode,pyrowave, and the pf-encode test leg (37 passed).
The knob tested `v == "0"` for the disable case and treated everything else that was set as
a force-enable. So a trailing space — the kind a `.env` line or a shell script leaves behind
— made `PUNKTFUNK_VULKAN_RGB_DIRECT=0 ` mean the exact opposite of what the operator wrote,
forcing the RGB-direct encode source on. On a cursor-blend session that is not a subtle
difference: the EFC front-end cannot blend, so the pointer disappears from the stream. An
empty value and any typo did the same thing.
Now parsed like every sibling knob in the crate — `matches!(v.trim(), "1"|"true"|"yes"|"on")`
and the matching false spellings — so unrecognised input falls back to the default instead
of being read as a force-on. `=0` and `=1` keep working exactly as documented.
Splits the parse into a pure function so the accepted spellings are covered by tests. That
matters more than it looks: the env-var read itself is untestable in a parallel test binary
(the process environment is shared), which is precisely why this knob's behaviour had no
coverage and the inverted case survived.
Verified with the canonical Linux gate (docker linux/amd64): fmt, clippy --all-targets at
default and at nvenc,vulkan-encode,pyrowave, and the pf-encode test leg (37 passed).
Every capability probe drops libav's log level to AV_LOG_FATAL around an encoder open it
expects to fail, then restores what was there before. That level is one process-global int
and the probes genuinely overlap — they are reached both from `/serverinfo` and from session
bring-up. Two overlapping save/restore pairs interleave as get(INFO) → get(FATAL) →
set(INFO) → set(FATAL), and the process is then pinned at AV_LOG_FATAL permanently: every
later libav diagnostic silently dropped, including the ones you want when a stream fails to
open later on.
Replaces the four hand-rolled save/restore pairs with one RAII guard over a single shared
mutex. The audit filed two sites; there are four — the NVENC 4:4:4 and 10-bit probes in
`linux/mod.rs` and both VAAPI probes, which is why the lock has to be shared across the two
modules rather than kept local to either.
Being RAII also closes a smaller hole the old shape had: the restore was a statement after
the open, so any early return added to those functions later would have leaked the quiet
level. Now it cannot.
The guard is poison-tolerant — a probe that panicked mid-window has already restored the
level through `Drop`, so refusing the lock forever afterwards would be strictly worse than
proceeding. It is not re-entrant, which is safe here because no probe body reaches another
probe (they only call encoder-open helpers); that invariant is written down at the type.
Serialising the probes costs nothing measurable: they are process-once behind their caches
and each already pays for a real encoder open.
Verified with the canonical Linux gate (docker linux/amd64): fmt, clippy --all-targets at
default and at nvenc,vulkan-encode,pyrowave, and the pf-encode test leg (37 passed).
`vk_av1_encode.rs` and `vk_valve_rgb.rs` are hand-copied `#[repr(C)]` structs handed to the
driver through raw `p_next` chains. Nothing in the type system relates them to the C
definitions any more, so an edit that inserts, drops, widens or re-pads a field is not a
compile error — it is the driver reading our bytes at the wrong offsets, silently. The
sibling vendored ABI in `amf.rs` has carried assertions for exactly this reason; these two
had none at all.
Adds size, alignment and per-field offset assertions for all 19 vendored structs. They are
`const` rather than `#[cfg(test)]` (the shape `amf.rs` uses) so they hold in every build
including the shipped one, and on any target the modules compile for.
Assertions cannot catch a swap of two same-typed fields — the offsets are unchanged — so
the field order was diffed field-by-field against the authoritative headers while writing
them: `vulkan_core.h` and `vk_video/vulkan_video_codec_av1std_encode.h` from Vulkan-Headers
`main` as of 2026-07-25. That diff covered every struct, every `ST_*` structure-type value,
every flag bit and both enum groups, and found no drift — the vendored copies are faithful.
The one remaining hand-copied table the compiler still cannot see is the bitfield member
order inside the three `*Flags` words, where a wrong index means the driver reads
`use_superres` where we meant `render_and_frame_size_different`. Three tests pin those to
the header by listing the members in C declaration order and asserting the Nth setter
writes bit N, with the trailing `reserved` field checked too — a dropped member shifts
`reserved` down and fails.
Verified with the canonical Linux gate (docker linux/amd64): fmt, clippy `--all-targets`
default and `nvenc,vulkan-encode,pyrowave`, and both test legs.
`NV_ENC_ERR_INVALID_VERSION` is how the driver reports two opposite failures, and we only
ever explained one of them. The message told the operator to update the NVIDIA driver or
reboot — correct for a genuine header/kernel-module skew, and actively misleading for the
field case behind it: a host that streams once per boot and then fails every later session
at the caps probe, until the *process* restarts. A version skew is static; it cannot come
and go inside one process, so that advice cost the reporter a reboot per stream.
Split the two on the only fact that tells them apart: whether a session has already opened
in this process. `nvenc_status` gains a `SESSION_OPENED` latch set right after every
successful `open_encode_session_ex` — both backends' caps probe and real open, plus the
Windows availability probe. No session yet, the version word really is in question and the
existing skew advice stands. A session already opened, and the kernel module demonstrably
accepted this build's version word, so the message now names per-process driver state and
points at the cheap fix (restart the host service, no reboot) plus a request for the log.
The load-time gate cannot serve as this discriminator: `NvEncodeAPIGetMaxSupportedVersion`
is a pure userspace query, so the classic "updated the driver, didn't reboot" skew sails
through it and only fails later at the open. Only a session that actually opened proves the
kernel module agreed.
The split lives in a pure `invalid_version(bool)` so both halves are unit-tested without
touching the process-wide latch. This is a diagnosis change only — it does not fix the
underlying field bug, whose root cause is still open.
Verified on Linux (192.168.1.25): clippy `-p pf-encode --features nvenc` clean, `cargo test
-p pf-encode --features nvenc --lib` 15 passed, rustfmt clean.
`33121ece` added a block explicitly labelled "TEMP KWin composite probe (DROP BEFORE
MERGE)" to prove the cursor blend was dispatching. It merged, and has been running on
every blended frame since: an atomic fetch_add per frame plus a `tracing::info!` with
seven computed fields every 512 frames, on the submit hot path of the default-on
Linux direct-NVENC backend.
The signal it existed for is already covered — the failure arm above it warns once
with the dispatch error, and the `else` arm warns when an overlay arrives with no
blend at all. What is deleted is only the success-path telemetry.
Verified `-D warnings --all-targets` + tests on Linux (default; shipped
nvenc,vulkan-encode,pyrowave), and `clippy --features vulkan-encode,pyrowave` on real
AMD RDNA3 hardware.

With `PUNKTFUNK_ENCODER=vulkan`, `open_video_backend`'s vulkan arm bails outright for
anything that is not HEVC/AV1 ("the Vulkan Video encoder supports HEVC + AV1; the
session negotiated {codec:?}"). But `host_wire_caps` for that same pref fell through
to the VAAPI probe / static superset, which includes H.264 — so the host advertised
H.264, a client could negotiate it, and the session died at encoder open.
The pref now contributes a CEILING that is intersected with the device probe, never a
replacement for it. That distinction is the whole fix: pinning a static HEVC|AV1
would have ADDED AV1 on the AMD/Intel hosts whose probe currently withholds it
(pre-RDNA3, pre-Arc), re-creating this very bug for a different codec. Intersecting
can only ever narrow.
Without the `vulkan-encode` feature the pref cannot open anything at all — that arm
bails with "requires a build with --features vulkan-encode" — so the ceiling is
empty there rather than optimistic.
Costs nothing on the handshake path: a `&str` match plus a const-folded `cfg!`.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
`LP_MODE` cached the resolved VAAPI entrypoint (full-feature `EncSlice` vs low-power
`EncSliceLP`/VDEnc) in a process-global array indexed by codec alone. That is not a
staleness bug, it is a session-killer, because the cache is load-bearing: once a mode
is latched the open tries exactly ONE mode and the `[false, true]` fallback is gone.
Latch low-power on an Intel Arc (Gen12+ removed the full-feature entrypoints, so it
is the only one that works there), then switch the web-console GPU preference to an
AMD dGPU. `render_node()` follows that preference, so every VAAPI open now goes to
radeonsi passing `low_power=1`, which it rejects — with no full-feature retry, for
the process lifetime. `probe_can_encode` reports all-false (so the advertisement
silently falls back to the static superset) AND the session's own encoder open fails.
Now keyed on (render node, codec, bit depth):
- The render node because the entrypoint is a property of the DEVICE libva opens,
and it is literally what `render_node()` hands libva — so key and device cannot
describe different GPUs. Deliberately not `pf_gpu::selection_key()`, which can
name a different adapter than the node actually opened.
- The bit depth because Main10 and 8-bit can resolve to different entrypoints on
the same device; one shared slot let an 8-bit answer pin the 10-bit open, i.e.
HDR under-advertisement.
Verified `-D warnings --all-targets` + tests on Linux (default; shipped
nvenc,vulkan-encode,pyrowave). The multi-GPU switch itself needs a box with two
VAAPI-capable adapters — owed on-glass.

`base_codec_mode_support` fell through to the static superset (H.264|HEVC|AV1) on a
GPU-less host, so Moonlight negotiated HEVC or AV1 and the session then died at
encoder open with "the software encoder emits H.264 only" — openh264 encodes nothing
else. The native plane's twin of this function, `pf_encode::Codec::host_wire_caps`,
has gated on exactly this since it was written; this one never did.
Deliberately a local gate rather than delegating wholesale to `host_wire_caps()`.
Delegation is the drift-proof shape and was the first design, but on Windows it
re-runs the DXGI adapter enumeration several times per `/serverinfo` GET — the probe
helpers each sample it uncached — and this endpoint is polled by every client. The
software case is a plain config read, so it costs nothing here.
Recorded in a comment rather than fixed: the static `MaxLumaPixelsHEVC` in the
serverinfo XML still advertises an HEVC limit even when the mask now drops HEVC.
Harmless (Moonlight gates capability on the mask, not the limit) but it is a second,
now-inconsistent advertisement.

`flush` looked dead — the only caller in the host is the `spike` dev subcommand — so
an audit sweep filed it as "wire it in or delete it". Both are wrong, and without
this note the next sweep will re-file it.
Wiring it in is refuted by control flow: both encode loops reach their exit only
AFTER the transport is gone (client disconnected, or the session stopped), so the AUs
a flush would recover have nowhere to go. And flush is the one call on this trait
that can BLOCK on a wedged encoder, on exactly the teardown path a stopped session
needs to finish promptly — the Linux direct-SDK NVENC retrieve-thread join is untimed,
so flushing there could hang a session that is already ending.
Deleting it is refuted by real consumers: `spike` encodes a FINITE clip and wants the
tail, and the `#[ignore]`d hardware smoke tests across the backends assert the drain
contract on real GPUs. Those are finite-stream users; a live session is not one.
Doc only, no behaviour change.

`open_video`'s `cursor_blend` argument was a request with no answer: lib.rs did
`let _ = cursor_blend;` and only three backends ever read `CapturedFrame::cursor`.
So a session could ask for a composited pointer, get a backend that silently
discards it, and stream with no mouse cursor and nothing in the logs. Two
separately-confirmed audit findings — the VAAPI dmabuf path and the libav-NVENC CUDA
path — are symptoms of that one hole.
`EncoderCaps::blends_cursor` makes it a fact each backend states. The four exhaustive
`EncoderCaps { .. }` constructors mean adding the field is a compile error until every
backend answers, which is the enforcement mechanism for future backends rather than a
side effect. Vulkan Video answers from its ACTUAL configured source rather than
statically: only the CSC path composites (`prep_cursor` feeds the compute shader),
while the RGB-direct/EFC front-end and the native-NV12 source have no compositing
stage at all and merely warn once that the pointer is being dropped.
`open_video` warns when a session asked for blending and the opened backend cannot
deliver it. A warning is deliberately all it does: `open_video` cannot re-plan
capture, so refusing would trade a missing pointer for a dead session. The host owns
`plan.cursor_blend` and is the only layer that can fall back to capturer-side
compositing — this gives it something to base that on.
Enforcement is NOT included. The reviewed design proposed refusing the client's
host-composite flip to keep the client drawing its own pointer, but `CursorRenderMode`
is client->host only: there is no host->client counterpart, so refusing yields no
pointer at all — the same failure it claimed to prevent.

`set_input_ring_depth` is a DEFAULTED trait method, so a caller that forgets it
fails silently — and one did. The GameStream loop opens an encoder
(gamestream/stream.rs:671 and the rebuild at :831) and never called it, while the
Windows IDD-push capturer declares a ring of 2 and `async_inflight_cap()` defaults
to 4. With PUNKTFUNK_NVENC_ASYNC=1 a Moonlight session therefore pipelined four
encodes against a two-texture ring, letting the capturer rotate a texture out from
under a live encode: torn or mixed frames, never an error — precisely the corruption
the cap exists to prevent, and precisely what the trait doc warns "fails silently and
intermittently".
Guarded at the single point of CONSUMPTION rather than by plumbing the setter into
every loop: `input_ring_depth` has exactly one reader in the workspace, so one
fail-safe covers every caller including ones not yet written, whereas fixing N call
sites only fixes the N someone remembered. An unconfigured ring is now treated as
the shallowest any capturer here declares, so the unconfigured path degrades to less
pipelining — a latency cost, not corruption.
The two GameStream sites also pass the REAL depth, because the fail-safe is a floor,
not a substitute: `idd_depth` is configurable and a deeper ring is free pipelining
the fallback would forfeit.
Default (sync) sessions are unaffected — the cap is only read while the async
retrieve thread exists, and that is opt-in.

Escalate-and-hold's missing half. The contention escalation (capture depth,
then the NVENC pipelined retrieve) was permanent: one sustained overrun — even
one CAUSED by the ABR overdrive's rebuild storms — cost the session its
depth-1 latency and its sub-frame streaming forever, and `encode_us` reported
queue depth instead of ASIC time for the rest of the session.
- The leaky bucket now keeps scoring after escalation. A sustained
every-frame-on-cadence run (~5 s at 120 fps) winds back one stage in reverse
order: pipelined retrieve first (its rebuild restores the IO-stream binding
and sub-frame chunked streaming), then capture depth back to 1. Attempts are
paced by an exponential backoff (1 → 5 → 25 min, capped) — a workload that
truly needs the escalation converges to keeping it, but never a permanent
latch.
- NVENC (Linux) implements `set_pipelined(false)`: a `want_sync` latch handled
at the same drained safe point as the engage side (`maybe_disengage_async`
mirrors `maybe_engage_async`); the lazy sync re-init re-arms everything and
opens on an IDR. The stream loop polls until the switch lands, then re-runs
the escalation warmup so the wind-back's own stall can't re-escalate it.
`PUNKTFUNK_NVENC_ASYNC=1` (operator-pinned async) refuses the wind-back;
the trait doc now specifies the two-way contract.
- While escalated, `cadence_degraded` stays latched (bitrate climbs refused)
even with the bucket drained: the headroom is spent, and climbs resuming
mid-escalation would saw against it and starve the clean run.

Host half of the §ABR-overdrive fix. The stream loop now reads
`Encoder::applied_bitrate_bps()` after every bitrate apply and stores THAT into
`bitrate_kbps`/`live_bitrate` — the send pacer, web console, mgmt registry and
control-task acks all track what the ASIC really targets instead of the
requested rate (the pre-fix ack promised 1.01 Gbps while the encoder ran
794 Mbps, and the client controller climbed from the phantom base forever).
- A short apply teaches `encoder_ceiling_kbps` (shared atomic): the stream loop
pre-clamps incoming requests to it and SKIPS the apply when nothing would
change — ending the reconfigure-reject → full-rebuild(~0.6 s + IDR) storm —
and the control task resolves future SetBitrate acks against it, so the
client learns the ceiling through the existing ack path (no wire change; old
clients converge too).
- `cadence_degraded` (shared flag, leaky-bucket level ≥ 10 or an escalated
session): while set, the control task resolves climbs to the current applied
rate — on a fat LAN no network signal ever stops a climb the encoder can't
serve, and past the compute knee more bits only deepen the cadence miss.
Descents always pass; they're the cure.
- Escalation-warmup hygiene: an ABR rebuild stall (~70 missed deadlines at
120 fps, 3.5× the escalate threshold) and the backlog scored against a
heavier rate no longer feed the latency escalation — rebuilds reset the
leaky bucket and re-run the warmup; in-place down-steps clear the bucket.

Two client-side halves of the §ABR-overdrive fix (the 4K120 sessions that
climbed to 1 Gbps against a 794 Mbps encoder and a 8.33 ms budget):
- Short-ack cap learning: the host now resolves a climb it can't serve to what
the encoder actually runs at (its codec-level ceiling, or the current rate
while encode is behind cadence). Two consecutive identical short acks latch
that value as a host cap the climb logic folds into its ceiling — one short
ack stays a transient (a failed rebuild also acks short once). The cap is
mode-scoped (cleared on an accepted mode switch, tracked via a mode
generation counter the control task bumps) and re-probes one step after ~60 s
parked clean, so a heavy-scene refusal can't quietly cap the whole session.
- Host-encode-latency down-driver: the per-AU 0xCF `encode_us` the host
already ships (and the overlay already draws) now feeds the controller
through its own window accumulator — the overlay channel is lossy and
embedder-drained, so the ABR gets a dedicated mirror of the decode-latency
path. Baseline-relative like the decode signal (an escalated host reports
encode_us inflated by ~a frame of queue depth; an absolute budget threshold
would read permanently red), with the baseline rebased after our own
decreases so one backoff doesn't train-fire into the floor. This is the only
signal that can push an already-too-high rate back under the encoder's
compute knee — host climb refusal stops the climb, but nothing else descends
on a clean LAN.

Three encode-time fixes from the 4K120 field analysis (sessions pinned ~107 of
120 fps, 14-15 ms reported encode):
- Ceiling truth: the codec-level bitrate clamp (binary search at session open)
now records its result in a process-lifetime advisory cache keyed by
GPU/config, so an ABR overshoot opens — or in-place reconfigures — straight
AT the ceiling instead of re-running the ~6-open search (and a full rebuild
+ IDR) on every overshoot. New `Encoder::applied_bitrate_bps()` exposes the
post-clamp rate so the session loop can stop pacing/acking a phantom
requested rate (consumed host-side in a follow-up).
- Clamp-search hygiene: only NVENC parameter/caps rejections steer the search
now (`NvCallError` keeps the raw status downcastable); a transient failure
(busy engine, session limit, OOM, driver skew) propagates instead of
shrinking into — and now caching — a bogus ceiling. The floor fallback also
records the split mode it actually opened with, so a later reconfigure
re-presents the real session params.
- Split-frame selection: one shared `resolve_split_mode` replaces the two
byte-identical direct-SDK copies; the force-2-way threshold moves to
`SPLIT_FORCE_PIXEL_RATE` (950 Mpix/s, shared with the libav path) because
4K120 = 995,328,000 px/s missed the old `> 1e9` gate by 0.47% and stayed on
AUTO — which never engages at 2160 px height, leaving the second NVENC
engine idle in exactly the mode the threshold existed for. The Linux
session-ready info! line now carries the final split mode (journals are
INFO+; this was undiagnosable from user logs).

09aa2db3 turned on `-p pf-encode --all-targets -D warnings` for Windows and removed
the crate-wide `allow(dead_code)`; together those surfaced two genuinely-dead items
in `nvenc,amf-qsv,qsv` — the combination the installer ships — and CI went red on my
own step.
- `WinVendor::Amf`: native AMF replaced the libavcodec AMF path in production, so
the only remaining CONSTRUCTOR is the `#[cfg(feature = "amf-qsv")]` latency A/B
in amf.rs — test code, so the lib target constructs it nowhere. The module
header already says this machinery is kept deliberately for that measurement, so
it gets a targeted `#[allow(dead_code)]` naming the reason rather than deletion.
- `probe_can_encode`: `lib.rs`'s only caller is under
`cfg(all(not(feature = "qsv"), feature = "amf-qsv"))`, because with the native
VPL backend compiled in `qsv::probe_can_encode` answers instead. Gated
`#[cfg(not(feature = "qsv"))]` to match its call site.
Both are real findings the blanket allow had been hiding; neither is a behaviour
change.
WHY THIS ESCAPED MY PRE-PUSH CHECKS, since that is the useful part: the Windows
runner I verify on has no FFmpeg dev tree, so `amf-qsv` could not build there and
`ffmpeg_win.rs` was compiled by NOTHING in my matrix — the same class of blind spot
this whole audit is about, reproduced by me. CI's own FFmpeg turns out to be cached
on that box at C:\Users\Public\ffmpeg, so the verification recipe now sets
FFMPEG_DIR and covers `nvenc,amf-qsv,qsv` (the CI command and my new step) plus
`amf-qsv` without `qsv` — the combo that still uses `probe_can_encode`. All three
clean.

The tray sat at "Idle" through an entire stream, and its Windows context menu
could come up without its main action. Two separate causes.
`GET /api/v1/local/summary` reported `video_streaming`/`audio_streaming` straight
from `AppState.streaming` — flags only the GameStream media pipeline raises. The
native punktfunk/1 plane is the DEFAULT (GameStream is opt-in) and never touches
them, so every native session read as idle: idle icon, and a tooltip that printed
that session's own resolution next to the word "idle" (the `session` field was
already native-aware). This is the blind spot `/status` was fixed for — see the
`session_status` module doc — which the summary kept. Both flags now OR in a live
native session, and the tray additionally treats a reported session as streaming,
so a new tray reads an older host correctly too.
The menu built "Open web console" (and the pairing entry) only while a live
loopback probe of the console had just succeeded. A console still starting, or an
SSR render slower than the 2 s probe timeout, therefore deleted the tray's
most-wanted action outright — indistinguishable from a tray that never had one,
with left-clicking the icon as the only, undiscoverable, way in. The entry is now
always present and the default item; a failed probe changes its label to
"(not responding)" instead of hiding it, and takes two consecutive misses to say
so, since one timeout is not "down".
While here: a "Release kept display…" entry when displays are held (the summary
field's own doc promised a one-click release that did not exist), and entries
deep-link to /pairing and /displays instead of all landing on the dashboard. The
Linux SNI menu mirrors all of it.

`linux_native_nv12_ok` is the verdict the host threads into capture negotiation
(session_plan -> OutputFormat::nv12_native -> ZeroCopyPolicy::native_nv12_session
-> pf-capture's prefer_native_nv12). Its doc claimed "the backend must be eligible
to open", but it asked only three static questions — codec is H265/AV1, an env
default, and a pref denylist — and never whether this GPU has an encode queue at
all. It could not: vulkan_video.rs exposed no probe.
That verdict is uniquely load-bearing. Once the producer has been asked for
two-plane NV12 there is NO fallback: open_video deliberately makes a failed Vulkan
open FATAL for an NV12 capture rather than degrading to libav VAAPI, because VAAPI
would import that buffer as packed RGB and stream silent garbage. So on a gamescope
host whose Mesa lacks Vulkan HEVC encode the session died at its first frame, while
the same host with PUNKTFUNK_PIPEWIRE_NV12=0 streamed fine — and the comment
promising such a device "degrades gracefully to the old backend rather than
breaking the stream" was stale on every gamescope host.
Two changes:
1. The gate. The third conjunct was a denylist of the EXPLICIT prefs that skip
Vulkan Video ("nvenc"|"nvidia"|"cuda"|"pyrowave"), which silently missed the one
that matters: the DEFAULT encoder_pref is "", and "" resolves to auto, which on
an NVIDIA box opens NVENC. A stock NVIDIA host passed this gate. It now consults
`linux_zero_copy_is_vaapi`, which layers the pref on top of the same auto
decision open_video makes — what the note on `linux_auto_is_vaapi` says a
capability probe must use, and what the downstream consumer of this very verdict
already uses. This alone was worth fixing; a probe added behind the old gate
would have opened a Vulkan instance on every NVIDIA handshake.
2. The probe. `vulkan_video::probe_encode_support` runs the FIRST check open_inner
performs and hard-fails on — the physical-device + encode-queue-family scan for
this codec's op — and nothing more, so it is provably no stricter than the open
and can never talk a working host out of the fast path. The scan is now a shared
`find_encode_device` used by BOTH, because a probe that mirrors a dispatch goes
stale the first time the dispatch grows a case (the failure open_video's
backend-label note already records). Cost: one instance plus physical-device
queries — no logical device, no video session, no VRAM — cached per (selected
GPU, codec) in the can_encode_10bit idiom, with the probe run outside the lock.
Per codec, not once: codec_op_for selects a different queue-family bit for AV1,
and HEVC-encode-without-AV1-encode is the common VCN/ANV configuration.
Later stages (create_device, create_video_session, the capability query) can still
fail for reasons the probe does not model. Those are harmless: the capture format
is only committed once the probe says yes, and everything after keeps the ordinary
packed-RGB negotiation.
Verified `-D warnings --all-targets` + tests on Linux (default; shipped
nvenc+vulkan-encode+pyrowave). The behaviour needs an on-glass check on the bazzite
RADV box — including the negative case, which `RADV_DEBUG=novideo` reproduces.

`submit_cpu`'s RGB24/BGR24 → rgb0/bgr0 expand ran `w*h` iterations per frame, each
building two bounds-checked sub-slices for a 3-byte copy plus a pad-byte store — a
shape LLVM will not vectorise into the byte shuffle it actually is. At 3840x2160
that is 8.3M iterations on the encode thread, per frame.
It is not an edge case. The module header says the portal commonly negotiates
packed 24-bit RGB, and pf-capture offers `VideoFormat::RGB` first because wlroots
commonly fixates it — so this was the mainstream CPU path, running roughly an order
of magnitude slower than the 4-bpp sibling branch (a plain row memcpy) purely
because of how it was written.
swscale's packed-RGB expanders are SIMD, the sibling VAAPI backend already routes
RGB24/BGR24 through them, and this file already owned the `sws_getContext` /
`sws_freeContext` lifecycle — so this is net subtractive rather than new machinery:
the existing CSC condition widens to include `expand`, and the hand-written loop
goes away. No new field, no second context, nothing added to `Drop`: `expand` is
false whenever `want_444` (see the `nvenc_pixel`/`expand` binding), so the three
users are mutually exclusive and one context serves whichever applies. The `expand`
field itself is gone with its only reader.
`sws_setColorspaceDetails` is now applied ONLY for the 4:4:4/HDR users. The expand
is a pure byte shuffle — NVENC does the RGB→YUV itself downstream — and handing it
a matrix and range would have silently range-converted every packed-RGB session,
which is exactly what the module header promises does not happen.
Verified `-D warnings --all-targets` + tests on Linux (default; shipped
nvenc+vulkan-encode+pyrowave). The pixel path itself is unverifiable without an
NVIDIA box: `nvenc_hdr10_smoke` and friends are #[ignore]d, so the channel order
and the pad byte want an on-glass check on the CachyOS 5070 Ti.

`sws_getContext` hands back a raw pointer whose only `sws_freeContext` lives in
`Drop for NvencEncoder` — and `Drop` needs a CONSTRUCTED `Self`, which does not
exist on either of `open`'s early returns: the intra-refresh-unsupported path
(which recurses into `Self::open`) and the plain error return. Both sit between
the context's creation and the `Ok(NvencEncoder { … })` that would give it an
owner, so every failed open leaked one.
That is not a once-per-process wart. `open_nvenc_probed` walks an EINVAL bitrate
ladder — requested rate, then the codec-level cap, then ×3/4 down to 50 Mb/s —
re-entering `open` at each step, so a GPU that refuses the requested bitrate leaks
a context per step (up to ~10). The intra-refresh retry adds one more.
Fixed structurally rather than with a guard: the block depends only on values known
before the encoder open (`want_444`, `want_hdr10`, `cuda`, `format`, `nvenc_pixel`,
the dimensions, `full_range_444`), so moving it BELOW `video.open_with(opts)` — to
just above the struct construction, with nothing fallible in between — makes the
leak unrepresentable instead of merely handled. No behaviour change: same context,
same colourspace details, same field.
Found while designing the WP1.4 swscale expand, which would have promoted this from
a 4:4:4/HDR-only leak (the only sessions that build a context today) to one on every
packed-RGB session. Fixing it first is the prerequisite for that change.

All three Windows backends derived it the same wrong way —
`bit_depth >= 10 || matches!(format, P010 | Rgb10a2)` at ffmpeg_win.rs:154,
amf.rs:1275 and qsv.rs:777 — so the NEGOTIATED depth could force a 10-bit encoder
over an 8-bit capture.
That combination is not hypothetical. A client advertises 10-bit, the handshake
negotiates bit_depth=10, and then enabling advanced colour on the IDD virtual
display fails — at which point the capturer says exactly that and delivers 8-bit
NV12 anyway ("10-bit HDR was negotiated but enabling advanced color on the virtual
display FAILED — encoding 8-bit SDR"). Every vendor then lost the session, each in
its own way:
- native AMF and native QSV derived `expected = P010`, saw Nv12, and bail!'d at
open;
- the libavcodec path accepted the open, built a P010 encoder, and then failed
EVERY submit forever, because its per-frame check recomputes the depth from the
frame and never matches. reset() could not help: the rebuild re-derived the
same wrong depth from the same stored bit_depth. The host burned
MAX_ENCODER_RESETS and ended the session.
The last one is the worst of the three because it IS the fallback: native QSV
correctly refuses this input at open, and lib.rs then falls back to the ffmpeg path
"for robustness" — which accepted it and died per frame instead.
Since the duplication was the bug, the fix is one shared `ten_bit_input()` in
codec.rs that all three call, and it follows the delivered pixels. That also keeps
the stream HONEST rather than merely alive: the depth selects the colour signalling
(BT.2020 PQ vs BT.709) and the staging surface format, so an 8-bit capture now
produces an 8-bit stream that says it is SDR — which is what the capturer already
reported it was sending. It warns when the negotiated depth is discarded.
The negotiated depth stays an upper bound. The session LABEL may still claim HDR;
that mismatch lives in the negotiation, not in the encoder, and is not addressed
here.
`is_10bit_format` keeps its (now format-only) definition and is used by
submit_d3d11's per-frame check, so the predicate the encoder was built from and the
one it re-checks per frame cannot drift. That check can now only fire on a genuine
mid-stream depth change.

The vendored rate controller packs the 32x32 block index into the low 16 bits of
`RDOperation::block_offset_saving` (pyrowave-sys patches/0002). Past u16::MAX the
index collides with the `saving` field, the resolve over-credits, and the emitted
payload can overshoot the buffer `pyrowave_encoder_packetize` writes into — whose
only bounds check is an `assert` that the Release (NDEBUG) vendored build compiles
out. There is no Rust-side guard behind it.
All three callers of `pyrowave_mode_fits_rdo` hardcoded 4:4:4, leaving 4:2:0
unchecked — but 4:2:0 overflows too, just later: 8192x6144 is 73728 blocks and
8192x8192 is 98304, while `Codec::PyroWave.max_dimension()` permits 8192 per axis,
so both are reachable from a client-requested `mode=WxHxFPS`. Worse, the host's
only use of the helper (native/handshake.rs) is a 4:4:4 -> 4:2:0 downgrade, so an
oversized mode was actively routed INTO the unguarded branch.
The cap now lives in `validate_dimensions`, checked against 4:2:0 — the most
permissive chroma, so a mode that cannot fit there fits no PyroWave session at any
chroma. That is the single chokepoint both the negotiator (handshake.rs:180) and
`open_video_backend` already run. Both encoder opens additionally check the chroma
actually being opened: the 4:4:4 half, plus defence in depth for the
`PUNKTFUNK_ENCODER=pyrowave` lab override.
Not dormant: punktfunk-host has `default = ["pyrowave"]` and no build passes
`--no-default-features`, so these backends ship in every host binary.
Tests pin the arithmetic (8192x6144 = 73728, 8192x8192 = 98304, 7680x4320 still
fits) and assert the cap does not leak to H.265/AV1, which have no such controller.

pf-encode's GPU backends are off by default, so almost none of them were under
`-D warnings`:
- ci.yml lints/tests with default features, which do cover VAAPI, libav-NVENC
and — via punktfunk-host's `default = ["pyrowave"]` — the PyroWave backends,
but not `nvenc` or `vulkan-encode`.
- deb.yml builds those two, but with `cargo build`, where warnings are not errors.
That left enc/linux/nvenc_cuda.rs, enc/linux/vulkan_video.rs and the vendored
vk_av1_encode / vk_valve_rgb bindings — ~8,150 lines carrying ~70 `unsafe` blocks —
never linted anywhere, so the crate's own
`#![deny(clippy::undocumented_unsafe_blocks)]`, its stated unsafe-proof gate, was
never actually enforced on them.
Linux gains a clippy+test leg at the SHIPPED feature set: deb.yml builds
`punktfunk-host/nvenc,punktfunk-host/vulkan-encode` WITHOUT
`--no-default-features`, so the .deb carries pyrowave too and that combination is
what deserves the lint. GPU-free — the hardware tests are `#[ignore]`d and
NVENC/CUDA dlopen their entry points, so the test binary links with no driver.
Windows gains a separate `-p pf-encode --all-targets` lint. The existing lint is
`-p punktfunk-host`, which never builds pf-encode's test targets — the blind spot
that let the Linux twin's tests rot. It must be clippy rather than `cargo test`:
on MSVC nvidia-video-codec-sdk link-imports NvEncodeAPICreateInstance /
NvEncodeAPIGetMaxSupportedVersion, so a test binary cannot link without the
driver's import lib. clippy type-checks without linking; ci.yml runs the tests.
`--all-targets` is load-bearing, not decoration: without it the feature-gated
`#[cfg(test)]` modules are never compiled at all.
Also widens windows-host.yml's paths filter, which listed `crates/pf-encode/**`
but none of the crates it compiles against (pf-frame, pf-gpu, pf-zerocopy,
pf-host-config, pf-capture, ...), so a change reaching the Windows host through
one of those triggered no Windows build.

Inherited from the pre-extraction host crate root as scaffolding for backend
paths defined ahead of the build that used them. A census across every feature
combination on both platforms (flip it to `warn`, rebuild) found it was hiding
exactly two items — so it bought nothing while blinding the crate to future rot:
- `vaapi::fourcc` — superseded by `pf_frame::drm_fourcc`; no call sites left.
- `vulkan_video::open_opts` — test-only (the smoke tests use it to pass the
RGB-direct request explicitly rather than through the env), now `#[cfg(test)]`.
Removing it surfaced a real latent defect the Linux census could not see:
`amf.rs`'s `percentile` / `drive_and_measure` helpers are used only by the
`#[cfg(feature = "amf-qsv")]` latency A/B benchmark, so a `--features nvenc,qsv`
build compiled the helpers with their caller gated out. They now carry the same
gate as their caller.
Verified `--all-targets -D warnings` on Linux (no features; shipped
nvenc+vulkan-encode+pyrowave) and Windows (no features; pyrowave; qsv; nvenc,qsv).

All ten `NvencCudaEncoder::open` call sites in the `#[cfg(test)]` module passed 9
arguments to a 10-parameter function: `cursor_blend` was added to `open` and the
tests were never updated. The module has been uncompilable ever since —
`cargo clippy -p pf-encode --features nvenc --all-targets` fails with 10x E0061.
Nothing in CI noticed because no job compiles this crate's feature-gated test
targets: ci.yml lints/tests with default features (which do not include `nvenc`),
and windows-host.yml lints `-p punktfunk-host`, which builds pf-encode as a
dependency and so never builds its test targets. The CI commit below closes that
gap; this has to land first or that leg starts red.
`false` is what these tests exercised before `cursor_blend` existed: every frame
they build sets `cursor: None`, and there is no cursor-blend test.

Field report (Nobara, 0.19.2): entering Game Mode mid-stream left the monitor
on and the stream mirroring at the desktop's resolution. Root cause: the
DM-flavor takeover needs privilege to stop plasmalogin, the polkit rule is a
docs-only manual step nobody installs, so every managed entry silently
degraded to ATTACH — and with a physical display connected the attach path
mirrors the box's own session at its own mode.
Ship the privilege with the packages instead: a root helper
(libexec/punktfunk/pf-dm-helper, verbs stop|restore) behind its own polkit
action (io.unom.punktfunk.dm-helper, allow_any — the same mechanism Nobara's
os-session-select uses, and the helper derives the DM unit from the
display-manager.service symlink itself so callers never name a unit across
the privilege boundary). The host tries the plain system-bus verbs first
(root / operator rule still take precedence), then pkexec's the helper; the
restore paths (idle restore + in-stream desktop-switch honor) use the same
ladder so a takeover that needed the helper can always be undone by it.
Packaged in rpm/deb/arch (Arch under /usr/lib/punktfunk with the policy's
exec.path annotation rewritten; the host probes both layouts). Nix is left
out deliberately: store paths can't match the probe, NixOS keeps the manual
rule. Docs updated — the rule snippet stays as the scoped alternative.

A fresh install left PunktfunkWeb registered but not running: `web setup` waited
only for the mgmt token before firing `schtasks /run`, while `web-run.cmd` also
requires the host identity cert — and the host writes the token during argument
parsing but `cert.pem` only after the pure-Rust RSA-2048 keygen inside `serve`.
The launcher lost that race, exited 1, and since the task carried no trigger but
boot (Task Scheduler does not reliably restart on a non-zero exit code) the
console stayed down until the next reboot, with the installer still reporting
"web console set up + started".
- `web setup` gates on cert.pem (written last) as well as the token, 90 s budget.
- After `schtasks /run`, poll for the :47992 listener and retry before giving up;
warn honestly instead of claiming a start that did not happen.
- `web-run.cmd` (installed + dev) waits in-process for the token + cert (~5 min)
rather than exiting 1 and hoping restart-on-failure retries.
- Register the task with a logon trigger alongside boot, falling back to the
boot-only XML if a Task Scheduler build rejects it.
- Linux had the same defect: punktfunk-web.service's Restart=on-failure gave up
permanently after systemd's default 5-starts-in-10 s limit. StartLimitIntervalSec=0.

An all-fixes patch on top of 0.19.1, all host-side:
- KDE Plasma display takeover moved off kscreen-doctor to in-process
kde_output_management_v2 (86d5d666), with the >60 Hz custom-mode install
ported too (64511af4) — a KWin host whose kscreen-doctor wedges now disables
its physicals and hands over the streamed output in ~2.4 ms instead of hanging
~26 s and never taking over.
- The gamescope managed takeover is display-manager-flavor-aware (e35dad52) so
switching a non-SDDM Linux desktop (Nobara / plasmalogin) into Game Mode no
longer start-limits the display manager into a permanent black screen, and
in-stream 'Switch to Desktop' is honored under it (a3e21d92).
- Windows display isolation anchors the kept sources at the desktop origin
(9b241d9d) so an origin-less desktop no longer fails 0x57, with restore
guaranteed never to leave the desktop all-dark.
- Windows pen/touch/absolute-mouse map over the streamed output's rect rather
than the whole virtual desktop (087e7d04), so absolute input lands correctly
when a physical monitor is kept on beside the streamed display.
Nothing moved on the wire (protocol 2) or at the C ABI (13), so no embedder
rebuild and 0.18/0.19 peers keep mixing freely. The Windows virtual-display
driver protocol is unchanged.

Pen, touch, and absolute mouse arrive normalized to the STREAMED display's
frame, but pointer_windows::to_screen and sendinput's MouseMoveAbs mapped
them over the whole virtual desktop — correct only when the virtual display
is the sole active display (Exclusive topology). In Extend — a physical
monitor kept on beside the virtual output, or an Exclusive isolate degraded
to the 0x57 keep-physicals fallback — the streamed output sits at a non-zero
origin, so every sample landed shifted and mis-scaled. The pen exposed it
first (field report 2026-07-24): a stylus is strictly absolute, with no
closed-loop correction onto the target like a cursor.
New pf-inject::stream_target (Windows): the host publishes the streamed
output's CCD target id at capture bring-up (one central site —
capture_virtual_output covers the native and GameStream planes); mapping
sites resolve its current desktop rect through pf-win-display's
source_desktop_rect — the same resolver the cursor-readback poller uses, so
inject and readback always agree — TTL-cached (250 ms) because a
group-layout re-arrange moves a live output's origin mid-session. No target
set / never resolved falls back to the whole virtual desktop (the historical
mapping, still right for Exclusive topology and devtest).
One change in to_screen covers pen + touch; MouseMoveAbs converts the same
desktop pixel into the 0..65535 MOUSEEVENTF_VIRTUALDESK coordinate, closing
the identical latent absolute-mouse bug (apollo-comparison open item #14/#30).

Follow-up to the previous commit: the only KWin topology op still shelling out to
kscreen-doctor was the >60 Hz custom-mode INSTALL (`set_custom_refresh`). Port it
to `kde_output_management_v2` so the whole KWin path is kscreen-free on modern KWin.
`kwin_output_mgmt::set_custom_mode` builds a one-entry `kde_mode_list_v2`
(set_resolution / set_refresh_rate / set_reduced_blanking=full / add_mode), applies
it via `kde_output_configuration_v2.set_custom_modes` (since 18), waits for KWin to
generate the mode (its CVT generator may align the width down — matched with the
same height-exact / width-within-8 / refresh-within-1Hz gate as before), then
selects it — which changes the output size and drives the sacrificial-birth stream
renegotiation. `kwin::create`'s want_high branch tries this first and only resolves
a kscreen id + calls `set_custom_refresh` if it returns None (pre-6.6 KWin without
set_custom_modes, or the compositor not answering) — so a >60 Hz session on a box
where kscreen-doctor wedges no longer eats a 5 s resolve timeout either.
Bonus: `set_custom_modes` REPLACES the custom list, so reconnects are idempotent —
no more one-custom-mode-per-connect growth of the user's display list.
Verified: cargo test -p pf-vdisplay (73 pass), clippy -D warnings clean, fmt clean.
The set_custom_modes round-trip is proven live on KWin 6.6.4: apply=applied, and a
1648x928@75 request generates 1648x928@74.901 (CVT fractional refresh, caught by the
1 Hz tolerance). The mode SELECT + full >60 Hz stream is still owed on-glass.

A KDE host on Nobara stopped disabling its physical screens and creating the
virtual output the moment it updated: streaming still came up, but bring-up took
~26 s and the streamed output never became the desktop (`also_disabled=[]`).
Root cause is not our topology logic — it's that every `kscreen-doctor` call on
the reporter's session wedges. kscreen-doctor drives libkscreen, which (per
setup) waits on the kscreen KDED module over D-Bus; when that layer is stuck it
blocks in its own connect and never returns, so all five topology queries hit
their 5 s budget and got killed (host log). Reproduced live on a Nobara / KWin
6.6.4 box: `kscreen-doctor -j` there times out at 8 s, every time.
But the compositor's OWN Wayland is fully responsive on that same session — the
host just created a virtual output over it via zkde_screencast. So drive the
topology (resolve our output, take primary, disable the physical/bootstrap
outputs, capture their modes, re-enable on teardown, position) directly over
`kde_output_management_v2` + `kde_output_device_v2` instead of shelling out.
On that same Nobara box the in-process path binds management (v19) and
enumerates the outputs in 2.4 ms — ~3400x faster than the 8 s hang, and immune
to whatever wedges the standalone tool.
- vendor kde-output-management-v2 / kde-output-device-v2 (KWin advertises mgmt
v19, device v20); generate client bindings inline (the interdependent-protocol
module split from the wayland-protocols crate; needs the `bitflags` dep for the
device protocol's bitfield enums).
- new `kwin_output_mgmt`: bounded enumerate-then-apply over one Wayland
connection; every wait is time-bounded so a genuinely wedged compositor
degrades to `handled = false` and the old kscreen-doctor path still runs.
- `kwin::create` topology + `apply_position` prefer the in-process path (address
our output by its stable device UUID, supersede-robust) with kscreen-doctor as
the fallback. The 60 Hz path now makes ZERO kscreen-doctor calls; only the
>60 Hz custom-mode install still shells out (its in-process port is a follow-up).
Verified on Linux: cargo test -p pf-vdisplay (73 pass), clippy --all-targets
-D warnings clean, fmt clean, punktfunk-host checks clean. In-process enumeration
proven live against KWin 6.6.4 (the reporter's env); the disable/apply path is
not yet on-glass.

First on-glass test of the DM-flavor takeover confirmed the black-screen
fix, but exposed that the managed model could not switch back: Steam's
in-stream session-select is a silent no-op while the display manager is
stopped (every config-write branch in os-session-select requires the DM
to be running), so the capture loss it causes just relaunched game mode.
The user pass of the switch script does leave one durable trace — the
~/.config/steamos-session-select sentinel, written before any DM check.
The managed launch now baselines its mtime; a capture loss with the
sentinel advanced reads as the switch request and is honored by
replaying the switch with the DM up: restore the display manager, run
the distro's own os-session-select (its internal pkexec is authorized
allow_any by the distro policy, so it works from the host's sessionless
context), then stop the autologin game-mode unit so Relogin lands in
the newly selected desktop. The capture-loss re-detection then follows
KWin as it comes up; a 120 s post-honor grace stops the rebuild loop
from racing the booting desktop back into game mode (superseded early
if the box's own game-mode unit reappears — the desktop→game leg stays
fast). The baseline is re-recorded on crash-restore so a pre-existing
sentinel never reads as a fresh request. Every verb in the sequence was
live-validated on the Nobara repro VM.

Field report (Nobara 43 HTPC): switching the host to Steam Game Mode
mid-stream permanently black-screened the box. Live-proven root cause on
a Nobara repro VM: our takeover masks the box's gamescope-session-plus
unit, plasmalogin's Relogin=true then fails its session Exec repeatedly
and trips systemd's start limit within ~1 s — the display manager dies,
and our restore verb (unmask + user start) cannot bring a seatless
gamescope back. Only 'reset-failed + restart' of the DM recovers.
The takeover is now display-manager-flavor-aware:
- SDDM (Bazzite/SteamOS) keeps the proven mask+SIGKILL path unchanged.
- plasmalogin/unknown DMs never mask: with privilege (root or an
operator polkit rule scoped to the DM unit — documented) the host
stops the DM for the stream and restores it with reset-failed +
restart (PUNKTFUNK_RECOVER_SESSION_CMD as fallback), recorded in the
persisted takeover state so a host crash still restores; without
privilege the managed takeover degrades to ATTACH and mirrors the
box's live Game Mode instead of destabilizing the seat. Both legs of
the privileged cycle live-verified on the repro VM (headless managed
session works with zero login sessions; render nodes are 0666).
A loaded-but-inactive leftover instance never triggers the DM stop.
Companion fixes from the same triage:
- ensure_box_gamescope_mode gains the attach-only rebuild-probe guard
both managed paths already had (stale post-capture-loss detection
restarted the box's unit), and no longer re-modes a box that drives a
physical display — attach mirrors on-glass; re-mode is the
headless-box model.
- Capture-loss rebuilds targeting gamescope get a 100 s budget: the
40 s budget expired inside the first 45 s Steam-cold-start launch
attempt, a guaranteed single-shot failure.
- A PUNKTFUNK_COMPOSITOR pin now WARNs once per capture loss when the
live session no longer matches it (the pin disables
session-following — the reporter's original stream-death trigger).
- A managed session that took nothing over (client gamescope pin beside
a live desktop) is stopped on disconnect instead of being orphaned
forever.

Round 3 of the field-reported exclusive-topology 0x57, with the reporter's
retest logs finally separating the variable: the SAME isolate call converged
rc=0 whenever a kept member already sat at (0,0), and failed 0x57 on every
shape — doomed-path-carried AND keep-only escalation — whenever the doomed
physical held the origin. A committable config must still contain a primary
(a source pinned exactly at (0,0)); deactivating the display that held it
while the kept virtual stays at its EXTEND offset supplies an origin-less
desktop, which Windows rejects wholesale. Translate the kept sources rigidly
so the top-left-most lands on the origin; sets already covering (0,0) are
untouched so plain re-commits stay byte-identical.
Also from the same logs:
- restore_displays_ccd now guarantees the desk is never left all-dark: the
saved snapshot can be unappliable (0x64a — it pinned a virtual target
incarnation removed before teardown) or apply cleanly yet re-light nothing
(snapshotted while an earlier failed teardown had the physicals off). If no
external physical is active after the apply while one is connected, fall
back to the database EXTEND preset. Internal panels don't count — a closed
lid must not be forced back on.
- the final isolate failure now names the surviving targets instead of
asserting 'a non-virtual display stayed active' — the logs showed a sibling
VIRTUAL display as the survivor (linger-expiry shrink), and the wording sent
triage the wrong way.

An all-fixes patch on top of 0.19.0. The headline is session teardown — the
native stop flag made enforceable and bounded (ac3dc432) and GameStream ending
on the control peer's ENet disconnect (41fa25c4), so a session can no longer
outlive the client that started it on either plane.
Also: the Windows input-desktop pair (display writes b5fa878b + pen/touch
injection 24a24734 both surviving a UAC prompt), the Apple display-sleep guard
(bc5f6a38), the gamescope corner-parked cursor (4b2d2d1e), the KWin custom-mode
selection (3a33a694), the tvOS glob warnings (cc8cccbe), and the Linux
starter/env docs revamp (66172753).
Nothing moved on the wire (protocol 2) or at the C ABI (13), so no embedder
rebuild and 0.18/0.19 peers keep mixing freely.

`punktfunk-core` emitted `unused import: super::super::*` for
client/pump/handshake.rs and client/pump/input_task.rs — but only when
built for a tvOS target, where the cfg set leaves the glob contributing
nothing. Nobody saw them because CI never builds tvOS: that needs
BUILD_TVOS=1 and the Tier-3 build-std nightly path, and the Apple
workflow only runs swift build/test (macOS).
Both files also `use super::*`, i.e. the parent `pump` module, which
itself globs `super::*` (`client`) unconditionally — so every name stays
reachable by that path and the inner glob was pure duplication. Their
sibling datagram_task.rs already imports only `use super::*`, so this
also makes the module consistent. control_task.rs and data.rs keep
theirs: those genuinely resolve names through it and never warned.
Verified warning-free AND compiling on every slice the xcframework
ships — aarch64/x86_64-apple-darwin, aarch64-apple-ios,
aarch64-apple-ios-sim, aarch64-apple-tvos, aarch64-apple-tvos-sim,
x86_64-apple-tvos — plus Linux with and without the `quic` feature. A
full xcframework rebuild now reports 0 warnings (was 6: two per tvOS
slice), and swift build, swift test (170 tests), and xcodebuild for the
macOS, iOS and tvOS schemes all pass.

Native sessions could survive long after the client was gone, in two
independent ways.
HOST: `stop` was only advisory. The one thing that ends a session is the
stream thread returning — every teardown (conn.close, the joins, and the
RAII drops of the session permit, admission entry and stream marker)
sits after that await, and nothing forced the issue. The encode loop
checks `stop` between iterations, so any unbounded call INSIDE one never
reaches the check, and one stuck syscall became a permanent zombie: it
held its semaphore slot (four of those and the host stops accepting
QUIC entirely), its admission entry (a later client gets "host busy"
forever), and not even the console's Stop button could clear it — that
button sets this same flag.
* Bound the wait: once the session has been told to stop, the thread
gets STREAM_STOP_GRACE (90 s, well past the 40 s capture-rebuild
budget) to return, then teardown runs anyway. The thread is detached,
not killed — Rust can't cancel a blocking thread — so it keeps its
capturer/encoder until the stuck call returns, but the session's slot
and admission entry come back and the host keeps serving. It logs at
ERROR as the host wedge it is.
* Bound the audio/input joins too — the last unbounded await in
teardown.
* Take the session permit AFTER the QUIC handshake instead of before
`accept()`, so a host at its concurrency cap still accepts and the
waiting client sees a live path instead of a silent dial timeout.
* Bound the compositor helpers that caused the wedge in the first
place: new pf-vdisplay `proc::{status_within, output_within}` kill a
child that outlives its budget. `kscreen-doctor` is a Wayland client
of the very compositor it configures, so against a wedged KWin it
never returned; same for systemctl/dbus against a stuck session bus.
CLIENTS: the connection was never closed, so the host was right to keep
the session — it still had a live, keep-alive-answering peer.
* Android: backgrounding did no teardown at all, and Android doesn't
suspend the process, so the worker kept answering keep-alives until
the OS reclaimed it (on a TV box, never). End the session on ON_STOP,
via the existing onDispose path; a plain close, not a quit, so the
host lingers the display for a fast return.
* Apple: the .background arm was iOS-only AND gated on an opt-in that
defaults off, so backgrounding did nothing — while the `audio`
background mode kept the app (and its connection) alive indefinitely.
Act unconditionally, and cover tvOS.
* Core: `conn.close()` only queues the frame, and run_pump is the body
of a block_on whose runtime is dropped the instant it returns, so the
driver could never put it on the wire — a deliberate quit reached the
host as silence (8 s idle timeout, no quit code, and the linger meant
for an unwanted disconnect). Carry the endpoint out of the handshake
and flush with wait_idle(), the same discipline the pairing and probe
paths already use.
Linux check/clippy/tests green: 262 host, 71 pf-vdisplay (incl. new
bounded-process tests), 231 core.

GameStream sessions outlived their client: the only complete teardowns
were the explicit ones (RTSP TEARDOWN, nvhttp /cancel, mgmt DELETE
/session), and the only automatic detector was a media-UDP send error —
which needs an ICMP port-unreachable, so a true vanish (Wi-Fi drop,
sleep, power off, crash) left video+audio encoding into the void
forever, and even a plain Moonlight quit (which sends neither TEARDOWN
nor /cancel) leaked the session. The stale state then cascaded: a
lingering launch 503-blocked a different client under
mode_conflict=reject, and streaming=true made a reconnect's PLAY take
its "stream already running" branch — no new threads, old threads still
aimed at the dead endpoint, the reconnect got no media.
ENet already detects all of this — the control peer's reliable-ping
timeout (or clean disconnect) fires Event::Disconnect within ~5-30 s —
but the handler only reset input state. Wire the real teardown into it:
* AppState::end_session — THE compat-plane session teardown: stops both
media threads (their flags), clears launch + negotiated stream config;
idempotent. /cancel and mgmt stop_session now share it.
* control.rs Disconnect → end_session. Gated on the TRACKED session
peer, and Connect only tracks a peer from the /launch owner's IP (the
same source-IP bind the RTSP/media plane uses), so an unauthenticated
LAN peer connect+disconnect can't end a live session, and a fast
reconnect's stale-peer timeout can't kill its successor.
* Client-unreachable UDP send errors now end the whole session via an
OnSessionLost callback (built at PLAY) instead of stopping only the
plane that noticed — audio no longer keeps streaming after video
detects the dead client, and vice versa.
Linux check/clippy/tests green (53 gamestream tests incl. the new
end_session regression test).

A KDE host streaming to a phone-shaped client fell back to 60 Hz even though the
120 Hz mode was sitting right there in KDE's display list, one manual click away.
KWin generates every custom mode's timing with libxcvt, whose first step is
`hdisplay_rnd = hdisplay - (hdisplay % 8)`. A 2868x1320@120 request (iPhone 16
Pro Max) therefore becomes 2864x1320@119.92 — 4 px narrower, fractional refresh.
We then asked kscreen-doctor for `mode.2868x1320@120`; its `findMode` matches a
mode's id or its own `WxH@qRound(Hz)` name, so that string matched nothing, the
select silently no-op'd, the output stayed on its sacrificial birth mode, and
`size_applied` came back false → "KWin rejected the custom mode" → 60 Hz.
Widths like 1920/2560/3840 are all multiples of 8, which is why only clients with
phone-shaped panels ever hit this.
Resolve the mode out of the output's OWN list instead and address it by kscreen
mode id: exact height, width at most one cell narrower than asked, refresh within
1 Hz (which excludes the native 60 Hz entry). `set_custom_refresh` now returns the
whole achieved mode, and `create` reports that as the output's `preferred_mode` —
so the capturer's renegotiation gate waits for the size KWin will actually deliver
and the encoder opens against it, rather than starving on the requested one.
Also skip `addCustomMode` when a usable mode is already installed: kscreen-doctor
APPENDS to the list and KWin persists it per output name, so the old code grew the
user's display list by one entry per connect.

Same field report as the display-write fix, other half of the symptom: with a
UAC consent prompt up — one the user could SEE in the stream, because capture
already renders the secure desktop (326d6e17) — pen and touch did nothing,
while mouse and keyboard kept working.
The split was exactly which paths knew the input desktop can move. sendinput.rs
reattaches, so mouse/keyboard reached the prompt. pointer_windows.rs had no
desktop handling at all, so every InjectSyntheticPointerInput came back
ERROR_ACCESS_DENIED:
22:20:31 virtual pen created (PT_PEN)
22:20:31 pen inject failed error=Zugriff verweigert (0x80070005)
22:20:42 touch inject failed error=Zugriff verweigert (0x80070005) contacts=1
Measured on glass before fixing, to find out what it actually takes:
device on Default, thread on Default -> 0x80070005 (the field failure)
device on Default, thread on INPUT -> OK
device on INPUT, thread on INPUT -> OK
The middle row is load-bearing: the synthetic pointer device is NOT
desktop-affine, so rebinding the thread suffices and the device is never
destroyed and recreated across a desktop switch — which would have dropped
in-flight contacts and the pen's in-range state mid-stroke.
Injection now retries once bound to the input desktop. The binding is scoped,
not persistent like sendinput's: inject_pen/inject_touch_frame run on TWO
threads (the caller's apply_batch and the refresh threads), and the batch caller
is a shared task thread that must not be left parked on a Winlogon desktop that
disappears when the prompt is dismissed.
The first-failure WARN now carries the rejected sample (flags, pen flags/mask,
pressure, rotation, tilt, position). A 0x80070057 INVALID_PARAMETER was seen
once BEFORE any prompt existed and is still unexplained; the ranges all look
sound on inspection (coordinates clamped to the virtual screen, roll/azimuth
u16 so the modulo cannot go negative, tilt bounded 0..=90), so catching the
actual offending sample is the way to find it.
Verified on glass: with a consent prompt up, pen and touch now reach it — zero
inject failures where every prior session failed immediately. A UAC prompt can
now be dismissed from an iPad with the Pencil.

Field-reported 2026-07-23: a consent prompt left up on an unattended host made
the box unreachable. Every connect black-screened and failed after ~60 s, and
the host had to be reached over SSH to clear the prompt.
Windows refuses ChangeDisplaySettingsEx/SetDisplayConfig issued from a thread
that is not on the desktop currently receiving input. While UAC (or the lock /
logon screen) is up that desktop is Winlogon, and the host — which the service
launches explicitly onto WinSta0\Default — got DISP_CHANGE_FAILED /
ERROR_ACCESS_DENIED for every write. A session starting in that window could
never set its virtual display's mode, so the capturer sized its ring to a stale
mode, every composed frame was dropped for a size mismatch, and bring-up burned
8 retries before giving up.
Measured on glass (RTX box, SYSTEM host in console session 2, real consent
prompt up, virtual display active):
INPUT desktop = Winlogon
UNBOUND CDS_TEST -> -1 (DISP_CHANGE_FAILED)
UNBOUND SDC_VALIDATE -> 0x5 (ERROR_ACCESS_DENIED)
BOUND CDS_TEST -> 0 (DISP_CHANGE_SUCCESSFUL)
BOUND SDC_VALIDATE -> 0x0 (ERROR_SUCCESS)
New input_desktop.rs mirrors pf-inject's sendinput.rs retry model: issue the
write, and only when it fails the way a wrong-desktop write fails, rebind this
thread to the current input desktop and retry once. A working write is never
touched, so the normal path is unchanged. The retry predicate stays narrow
(ERROR_ACCESS_DENIED only) so the unrelated 0x57 exclusive-mode topology bug is
not re-issued and mis-attributed. Unlike sendinput's dedicated injector thread,
the binding here is SCOPED — a shared display-write thread left on a Winlogon
desktop that is later destroyed would fail every subsequent write, which is the
wedge this removes.
Applied to all eight SetDisplayConfig sites and both ChangeDisplaySettingsExW
calls in set_active_mode. The isolate site now decides its supplied config once,
outside the write, so a retry re-issues the identical config rather than logging
its escalation twice.
A save is logged, because a silent one is indistinguishable in a field log from
a write that never needed saving — which made the first on-glass verification of
this change inconclusive.
Both ACCESS_DENIED diagnostics now ask which cause applies instead of naming
only the disconnected-RDP one: that phrasing sent this investigation chasing a
phantom RDP session on a host that was already service-launched in the console
session, while a consent prompt was the actual cause.
Verified on glass: connect with a consent prompt up now reaches first frame in
3.0 s (was a black screen then "Connection failed" after ~60 s), with six
"retried bound to it and it applied desktop=Winlogon" lines and rc=0x0
throughout.

gamescope hides its pointer by WARPING the X pointer to the root's bottom-right corner pixel;
it does not swap in a transparent X cursor, so XFixesGetCursorImage keeps handing back the last
opaque arrow. The XFixes source picked its display by "whichever pointer moved", and a parked
pointer never moves again — so it froze on the parked Xwayland and composited that arrow at
(w-1, h-1): a sliver of cursor welded to the corner of the stream for the rest of the session
while the real pointer went undrawn. Reported on-glass in every game (a game grabs the pointer,
so the hide is permanent): "part of cursor shows up on bottom right ... isn't where it really is".
Follow GAMESCOPE_CURSOR_VISIBLE_FEEDBACK instead — gamescope publishes it on every nested
Xwayland root: 1 on the server whose pointer it is drawing, 0 on the others and 0 on all of them
once the pointer is hidden. It answers both questions correctly for a STATIC pointer, which
motion cannot: which Xwayland owns it, and whether to draw it at all. Read at connect, re-read
on its root PropertyNotify (event drain now discriminates CursorNotify vs PropertyNotify) with a
250 ms resync as the self-heal. A pointer gamescope draws nowhere is published visible:false,
not dropped — the encode loop overwrites the frame's overlay from this slot and strips invisible
ones, so a None would leave the last visible overlay standing on repeat frames. Honouring the
atom also gives the stream gamescope's own idle auto-hide, which this source never had.
The pointer-motion heuristic stays as the fallback for a gamescope that publishes no verdict
(logged at session start via cursor_feedback=false), so nothing regresses to a cursorless stream.
Measured on a live 1920x1080 Steam Gaming Mode session (RTX 5070 Ti, gamescope c31743d+,
--xwayland-count 2 --hide-cursor-delay 3000): idle 3 s => pointer (1919,1079) + feedback 0;
real evdev motion => pointer live + feedback 1. End-to-end against that session the source now
publishes visible=false while parked and tracks the live pointer within one 250 ms sample of
motion. cargo clippy -p pf-capture --lib -D warnings and the 5 new pick_active tests are green
at cargo 1.96.1 (CI parity); cargo fmt --all --check clean.
A stream is not user activity to the OS, and controller input does not feed
the HID idle timer on any Apple platform — so a gamepad-only session reliably
idles the panel out from under the user mid-play. A keyboard/mouse capture
session masks the bug because those events are real local HID. The Android
client has held FLAG_KEEP_SCREEN_ON while streaming all along; the Apple
clients held nothing.
DisplaySleepGuard is acquired in beginStreaming and released at the top of
disconnect, so it is scoped to the session — every teardown path (user quit,
sessionEnded, the backgrounded keep-alive timeout) funnels through disconnect.
iOS/iPadOS/tvOS: UIApplication.isIdleTimerDisabled. App-wide and ignored
while backgrounded, which is what the audio-only keep-alive wants.
macOS: ProcessInfo.beginActivity(.userInitiated, .idleDisplaySleepDisabled),
the Foundation wrapper over IOKit power assertions. That defers display
sleep but NOT the screen saver, which runs off the HID idle timer
independently — so a 30 s IOPMAssertionDeclareUserActivity heartbeat runs
alongside it. Intended side effect: an idle-lock that follows the screen
saver is deferred for the session too.

Field triage (Nobara, Discord): the kde.md starter host.env told desktop
users to set PUNKTFUNK_COMPOSITOR=kwin, which PINS the backend — detect()
short-circuits and the capture-loss rebuild never re-detects — so a
mid-stream switch to Game Mode killed the stream instead of following it.
A follow-up hardcoded XDG_RUNTIME_DIR=/run/user/1000 anchor broke PipeWire
for any non-1000 uid (pw audio connect: Creation failed).
Revamp across every starter/example/reference:
- Desktop starters (kde/gnome/hyprland/sway) shrink to
PUNKTFUNK_VIDEO_SOURCE=virtual + an explicit warning that pinning
disables session-following; forcing a backend is CI/appliance-only.
- host.env.example: rewritten around auto-detection; anchors demoted to a
commented ssh/cron-only block with the uid trap spelled out; the
gamescope ATTACH/MANAGED knobs documented (previously missing);
case-sensitivity called out.
- packaging/bazzite/host.env + README: drop the uid-1000 anchors (a
systemctl --user service inherits/derives them); README's stale
PUNKTFUNK_COMPOSITOR=gamescope-era template synced to the real one.
- packaging/kde/host.env: loud APPLIANCE-ONLY header (it pins on purpose).
- configuration.md: session-anchors section inverted to "leave unset",
compositor row states the pin consequence, case-sensitivity note.
- troubleshooting.md: new "session fails right after editing host.env"
section (case, wrong-uid anchors, stale pin, restart-to-apply).
- gamescope.md/bazzite.md: attach/managed descriptions match current
behavior (managed is the infra-detected default; attach re-modes a
box-owned session to the client's resolution).

Release notes were written for the people who build Punktfunk, not the people who use it —
dense with protocol/ABI/type names that confused even technical readers. Rewrite v0.19.0 in a
benefit-first, plain-language voice (New/Improved/Fixed) with all internal terms removed from the
body and every protocol/ABI/embedder detail moved to a single bottom "Under the hood" section.
docs/releases/README.md now codifies this voice as the format spec for all future notes.

The v0.19.0 deb + decky release-attach steps source gitea-release.sh under `sh` (dash) and
died with "Bad substitution" at _release_notes_path's `${BASH_SOURCE[0]:-$0}` — a bash array
subscript dash rejects. So those legs never attached their assets to the release (the bash
legs — apple, android, rpm — were fine, which is why the body still seeded and the DMG/.ipa
attached). CI always sources this from the repo root, so resolve the notes as
docs/releases/<tag>.md relative to CWD and drop $BASH_SOURCE entirely. Verified under dash.

Headline: the whole pen/tablet input stack (P0–P5) — a pressure-sensitive stylus plane
across core wire, Linux, GameStream/Moonlight, Windows, iPad Pencil and Android. Plus
touch-injection fixes, cursor-DPI scaling, three Windows-host display/cursor fixes, a
gamepad same-PID conflict fix, and the Android mouse/keyboard (TV) regressions.
Release notes authored in-repo at docs/releases/v0.19.0.md (first release on the new flow;
CI seeds the release body from it). cargo update --workspace syncs the lock (versions only).

The pen P0 work added a new embeddable C entry point (punktfunk_connection_send_pen)
but left ABI_VERSION at 12 — the value 0.18.0 shipped. Per the project's convention
(0.18.0 bumped to 12 for the additive cursor channel), additive C-surface growth bumps
the ABI so embedders can gate on the new symbol. Regenerated include/punktfunk_core.h
via cbindgen (cargo build -p punktfunk-core); WIRE_VERSION is unchanged (pen is
capability-gated on HOST_CAP_PEN).

The iOS leg archives with development signing and re-signs for App Store distribution at
export time, but the existing export uses destination=upload (straight to TestFlight) and
leaves no .ipa on disk. Add an export step that re-exports the SAME archive with
destination=export to produce an App Store distribution-signed .ipa, then:
* attach it as the `punktfunk-ios-ipa` run artifact on every build (upload-artifact@v3,
since Gitea's backend rejects @v4), and
* attach it to the unified Gitea release on vX.Y.Z tags (alongside the DMG), via the
shared ensure_release/upsert_asset helpers.
Same gate as the archive; warn+skip (never fails the best-effort iOS leg) if the archive is
absent. Note: an App Store-signed .ipa installs only via TestFlight/App Store, not by direct
sideload — it is a release/archival artifact.

The hex dumps from the on-glass session show textbook SS_TOUCH packets with
pressureOrDistance = 0x7fc00000 (NaN): VoidLink encodes 'unknown finger
pressure' as NaN (iPad fingers have no force sensor), and the anti-forgery
finiteness gate rejected the entire packet — silently disabling the touch
plane while pen (real Pencil force, always finite) worked. Coordinates keep
the strict gate (they feed injector scaling); pressureOrDistance now
sanitizes non-finite to 0.0, the spec's own 'unknown', which the pen path
already maps to full-scale ink on contact.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
An on-glass 'touch does nothing' currently leaves NO trace: log the first
SS_TOUCH per session at info (proves the client sends + we decode), and warn
when a packet carrying a pointer magic fails the body parse (layout mismatch)
instead of vanishing into the unknown-magic drop.

Two Android TV M&K regressions from the c90343c2 overhaul, both user-reported:
1. Mouse back/forward buttons doubled as Android navigation while streaming.
The BUTTON_BACK/FORWARD motion edges already go over the wire as X1/X2, but
Android's input reader ALSO synthesizes KEYCODE_BACK/FORWARD key events from
those buttons unconditionally (stamped SOURCE_MOUSE, no FLAG_FALLBACK) — and
the guard only swallowed the FLAG_FALLBACK variant, so the duplicate reached
the BackHandler and yanked the user out of the stream. Swallow mouse-sourced
BACK/FORWARD too; a remote/keyboard BACK is never mouse-sourced and still
exits.
2. The soft keyboard popped up on physical-keyboard typing. KeyCaptureView (the
always-focused IME/capture anchor) unconditionally claimed to be a text
editor with a live editable InputConnection, so the TV IME counted input as
active and showed its UI the moment hardware keys arrived. Gate the editor
identity on imeShown (the user actually summoning the keyboard via gesture /
remote toggle), with restartInput on both edges so the gate is re-read, and
an onKeyPreIme BACK hook so an IME self-dismissal can't leave the gate
stale.

Field bug (Steam Deck client, exclusive topology): every isolate retry failed
SetDisplayConfig 0x57 with the physical panel left lit, while iPhone sessions
worked — their virtual monitor's connected-set already had a sole-display
topology persisted, so Windows deactivated the physical on hotplug and the
isolate was a no-op re-commit (deactivated 0). The Deck's monitor identity had
no such entry, forcing the live-deactivate path: supplying the doomed path
(inactive, modes unpinned) plus its orphaned mode entries is rejected 0x57 by
some driver/OS validation combos, so the retry loop could never converge — the
prior mode-index unpin (5e088af7) was necessary but not sufficient on this box.
Attempt 1 keeps the shipped shape; once a survivor is seen, later attempts
supply ONLY the keep paths with the mode table rebuilt to just their referenced
entries (indexes remapped, clone-shared entries deduped). The same host applies
exactly this keep-only shape rc=0 whenever the DB has pre-isolated the virtual
display, so the escalated shape is field-validated on the failing machine. The
final attempt also drops SDC_FORCE_MODE_ENUMERATION — a real path removal
drives COMMIT_MODES on its own.

On-glass report (iPad Moonlight vs the Windows host): pen inked, native touch
did nothing. Cause: POINTER_INFO.pointerId was the client's raw wire id —
Moonlight sends arbitrary large pointerIds, and synthetic-pointer injection
rejects them (Apollo compacts ids into dense slots for exactly this reason);
the failure was logged at trace, i.e. invisibly. Wire ids now map to the
lowest free slot for the contact's lifetime, and the FIRST injection failure
of a device logs at WARN (pen too) so an inert input plane is never silent
again.

The Android leg of design/pen-tablet-input.md §7: against a HOST_CAP_PEN host,
stylus/eraser pointers split out of BOTH touch models (passthrough + gesture)
into StylusStream — state-full samples with pressure, AXIS_TILT, azimuth from
AXIS_ORIENTATION (Android's 0 = away-from-user IS wire north), AXIS_DISTANCE
hover, both stylus barrel buttons, the eraser tool, and historical (coalesced)
samples batched oldest-first. Kotlin heartbeats ≤100ms per the wire contract.
JNI: nativeHostSupportsPen + nativeSendPen (flat 10-float stride, sentinels
<0). No barrel-roll axis exists on Android — roll stays unknown here.

The flagship leg of design/pen-tablet-input.md §7: against a HOST_CAP_PEN host
the Pencil splits out of the finger path (independent of touch-input mode) into
PencilStream — state-full samples with force→pressure, altitude→polar tilt,
azimuth (+90° to the wire's north-clockwise convention), Pencil Pro rollAngle→
barrel roll (17.5+), coalesced touches batched ≤8/send for full 240Hz fidelity,
and Pencil hover (zOffset>0 distinguishes it from trackpad hover) as in-range
samples with distance. Squeeze holds barrel 1, double-tap clicks barrel 2 (the
Pencil has no hardware buttons/eraser — these are how host apps get those
affordances). Implements the ≤100ms heartbeat wire contract (80ms timer) so a
stationary held stroke survives the host's 200ms dead-client failsafe. Toward a
pen-less host nothing changes (Pencil stays a finger).
Also fixes hostSupportsCursor testing the STALE 0x04 bit — HOST_CAP_CURSOR
moved to 0x08 when TEXT_INPUT claimed 0x04; the old test would mistake a
text-input host (e.g. Windows) for a cursor grant and double-render the pointer.

Release notes now live in the repo at docs/releases/vX.Y.Z.md, authored during the
version bump (before the tag). ensure_release (gitea-release.sh + .ps1 twin) seeds the
Gitea release body from that file in the create POST, so the release is born WITH its
notes instead of being created empty and PATCHed afterward. canary/rc have no file ->
empty body, unchanged.
New manual `announce` workflow (workflow_dispatch, tag input) re-syncs the notes file
over the live release and posts a violet embed (title, notes lead-in, release-page link)
to the Discord #releases channel via the DISCORD_RELEASE_WEBHOOK secret. Stable-only:
a -rc tag is refused unless allow_prerelease=true. Pressing "go" is the quality gate, so
a half-built or failed release is never announced.
docs/releases/README.md documents the ritual; TEMPLATE.md is the skeleton.

Parity with the Apple client (35c2c145): the SDL/Linux presenter built the
host-forwarded cursor as an OS cursor at its native bitmap size, so the
on-screen pointer tracked the HOST's display scaling — a 4K/high-DPI virtual
display forwards a 96 px bitmap that then rendered huge on the client.
SDL cursors are fixed-size from their surface (no draw-time scaling), so
cache the shapes RAW and resample each by the live video-fit factor
(min(window_px / mode) — the same aspect-fit `finger_to_content` uses) at
install time, rebuilding when the serial OR the fit changes (a resize). The
resample area-averages on premultiplied alpha so a transparent pixel's
colour can't bleed into the fringe. The pointer now stays sized to the
streamed desktop at any host scaling.
Not yet eyeballed on a Deck/Linux box — SDL's HiDPI cursor sizing is
version-dependent; validate on glass.

The Windows leg of design/pen-tablet-input.md §6, following Apollo's recipe:
a per-session PT_PEN device (pressure rescaled 0..1024, polar tilt→tiltX/Y,
barrel roll on rotation — Windows Ink renders Pencil Pro roll natively, barrel
button, eraser via INVERTED/ERASER flags, hover) with a 40ms refresh thread
against the ~100ms synthetic-pointer staleness auto-lift, plus a PT_TOUCH
device closing the historical SendInput wire-touch no-op (full active-contact
frames, per-id DOWN/UP edges, self-healing lost-DOWN synthesis). pen_supported
now probes PT_PEN creation on Windows (1809+), which lights up HOST_CAP_PEN
and the GameStream featureFlags there — Moonlight iPad + Pencil can ink on a
Windows host. Frame grouping mirrors the Linux uinput backend.

The Moonlight leg of design/pen-tablet-input.md §4: DESCRIBE now advertises
SS_FF_PEN_TOUCH_EVENTS wherever pen injection exists (Linux+uinput, same gate
as HOST_CAP_PEN — elsewhere the flag stays 0 and Moonlight keeps client-side
mouse emulation exactly as today). SS_PEN packets merge over last-known state
into state-full PenSamples (BUTTON_ONLY per spec carries no position; unknown
contact pressure 0.0 inks at full scale; UP keeps proximity only for clients
that demonstrated hover) and drive the same PenTracker→VirtualPen chain as the
native plane — Moonlight iOS + Apple Pencil now exercises the full injection
path end to end. SS_TOUCH forwards as wire touch on a synthetic 65535² surface
with CANCEL_ALL replayed per tracked contact. No stroke timeout on this plane:
ENet is ordered/reliable and Moonlight doesn't heartbeat a stationary pen.
Packet layouts pinned against moonlight-common-c Input.h/Limelight.h upstream.

The Linux injection leg of design/pen-tablet-input.md: 0xCC/0x05 pen batches now
route through the per-session PenTracker into a lazily-created 'Punktfunk Pen'
uinput tablet (BTN_TOOL_PEN/RUBBER, pressure, tilt-from-polar, ABS_Z barrel
roll, hover distance, INPUT_PROP_DIRECT) — compositors pick it up via libinput
and hand apps zwp_tablet_v2 with full fidelity. The host now advertises
HOST_CAP_PEN when /dev/uinput is accessible (PUNKTFUNK_PEN=0 kill-switch);
transitions group into SYN frames so proximity-enter carries its position.
Stroke failsafe: clients heartbeat ≤100ms while in range (documented wire
contract — capture APIs are silent for a stationary pen); 200ms of silence
force-releases. 'punktfunk-host pen-test' draws a pressure-ramped sine stroke
through the real tracker→uinput chain, no client needed.

Field report (iPad via GameStream, 2026-07-23): cursor missing from the
stream. The session's fresh target 257 reported cursor_excluded=false
(DECLARED_TARGETS is keyed per target and only 259 had declared), so the
host skipped forced-composite — but DWM's pointer exclusion after an
IddCx hardware-cursor declare reaches EVERY later monitor of the adapter,
not just the declaring target (proven on-glass: declare on 259 under
WUDFHost 2192, then 257's frames streamed pointer-free with CURSOR_SHOWING
set and SM_MOUSEPRESENT true). GameStream/Moonlight clients cannot draw a
forwarded cursor, so those sessions were silently cursor-less.
ADD replies now report any-declare-this-WUDFHost-life (the state's real
scope — it dies with the adapter reset, same as before); per-target ids
stay only as the dbglog audit trail. Channel-less sessions on a declared
adapter then hit the existing forced-composite gate (GDI poller + blend)
and carry the pointer in-video. Host code unchanged.

The Mac client drew the host-forwarded cursor bitmap at its native pixel
size (pixel-as-points), so the on-screen pointer tracked the HOST's display
scaling: a 4K/high-DPI virtual display renders a 96 px pointer, which then
appeared huge on the client — and on retina every pointer was already
2x-inflated and upscaled-blurry, since the backing scale was ignored.
Cache the shape raw and rebuild the NSCursor at the live video-fit factor
(fit.width / mode.width — the same AVMakeRect fit the input mapping uses)
on each apply, re-fitting on resize / retina moves. The pointer now renders
at its true size relative to the streamed desktop at any host scaling:
crisp and 1:1 with the video at 100%, and proportional (not ballooning)
when the host sits at 200-300% — including a deliberately raised scale.
iOS/tvOS (UIPointerInteraction) and Android (no forwarded-bitmap path)
render the pointer differently and need no change; the SDL/Linux client has
the same native-size issue and will follow.

0.18.0 regression: UAC consent and Winlogon (lock/logon) stopped appearing
in streams. The cursor channel's IddCx hardware-cursor declare — re-issued
by the driver on every swap-chain assign — keeps the path out of the OS's
software-cursor mode, which is the only mode the secure desktop renders
through; DWM then never presents UAC/Winlogon into our swap-chain and the
stream repeats the last normal-desktop frame for the whole interaction.
The GDI cursor poller now classifies the input desktop on its reattach
cadence (UOI_NAME != Default = secure, 250 ms cadence instead of 2 s), and
the capturer edge-triggers the existing-but-unused proto-v6
IOCTL_SET_CURSOR_FORWARD flip: OFF at secure entry (the driver stops its
per-assign re-declare; the host facade forces the same-mode re-commit that
actualises the software-cursor default, under the vdisplay manager lock via
the new force_recommit()), back ON at dismissal for channel sessions.
Channel-session open resets the driver's persisted desired state to ON so
a session that died mid-secure-desktop can't leave the next one adopting
UNdeclared (the §8.6 cross-session composite trap); orderly teardown does
the same. The flip closure is built for every Windows session — a
channel-less session can reuse a driver monitor whose earlier-session
cursor worker still re-declares, and NOT_FOUND from never-declared targets
is ignored.

The Steam-conflict gate matched any physical Valve `28DE` HID device, so a
Steam Machine with a physical Steam Controller 2 (`28DE:1302`) plugged in
degraded a client's requested virtual Steam Deck (`28DE:1205`) to a DualSense
— the reporter's controller passthrough came up as the wrong pad.
Steam Input drives *distinct* Steam controllers side by side; only two
*identical* `28DE` devices confuse it (the Deck-as-host case: built-in
`28DE:1205` + a second virtual Deck, observed live on Bazzite). Narrow the
gate to key on the exact VID+PID instead of the `28DE` vendor alone:
- `steam_backend_product()` maps each virtual Steam backend to the PID it
enumerates as (Deck 1205, classic SC 1102, SC2 1302, SC2 Puck 1304).
- `physical_steam_controller_present()` -> `physical_steam_product_present(pid)`
matches `:28DE:{PID}`, keeping the FVPF-serial / `vhci_hcd` / `/virtual/`
exclusions so our own virtual pads never count.
- `degrade_steam_on_conflict` degrades only on a same-PID duplicate and logs
the conflicting identity. `PUNKTFUNK_STEAM_FORCE=1` override unchanged.
A physical SC2 no longer blocks a virtual Deck (and vice versa); a genuine
same-identity duplicate (physical Deck + virtual Deck, or physical SC2 +
SC2 passthrough) still degrades. Adds a unit test for the PID mapping.

The pen plane from design/pen-tablet-input.md, protocol side only (the P1 uinput
tablet injector will consume it): 0xCC kind 0x05 carries batches of state-full
PenSamples (pressure, polar tilt + azimuth, barrel roll, hover distance, eraser

Steam's "Add a Non-Steam Game to My Library" entries carry no `appmanifest`, so
`scan_manifests` can't see them and they never appear in the streamed library.

(a binary KeyValues parse) to surface the user's own custom entries, plus their

The visible "Punktfunk" shortcut's Steam appId is cached in SteamUI
localStorage, which lives in Steam's CEF profile — so it survives a
plugin uninstall/reinstall. Deleting the shortcut left the key dangling;
on the next mount ensure*Shortcut recalled the dead appId, took the reuse
branch, and ran SetShortcut* against a non-existent id (silent no-ops).
AddShortcut was never reached, so the entry never came back. The same
stale-reuse also made the hidden stream shortcut RunGame a dead gameid.
Verify the remembered appId still maps to a live shortcut via
appStore.GetAppOverviewByAppID before reusing it; a confident miss falls
through to AddShortcut. When appStore is unavailable, assume it exists so
a false negative can't spawn a duplicate library entry.
Also add a "Recreate library shortcut" recovery button to the QAM About
section (recreateShortcuts): drops any dead cached keys and re-ensures.
Covers deleting the shortcut without reinstalling, where no mount fires
the self-heal.

the version-coherence assertion still pinned v5 (hidden behind that compile
error). Cover the new tail bytes + the legacy-size constant, and widen the

undici/postcss/js-yaml — bun ignores range-scoped override keys, so plain keys)
and a full lockfile re-resolve, which also lifts brace-expansion 2.1.1→2.1.2
in place while its 5.x line (minimatch@10) stays untouched. : No

The KWin/Phase-A/B commits were built but never clippy-checked (that distrobox
had no clippy component), so they left TEMP on-glass probes and lint debt in the
tree. With clippy now runnable (fedora rust 1.96.1 = CI parity):
- drop the `fec424ee`/`8cff30d5` TEMP probes: the `update_cursor_meta` SPA_META
diagnostic logs (also un-detaches the `// SAFETY:` comment from its `unsafe`
block → fixes `undocumented_unsafe_blocks`) and the KWin composite-arm probe in
the encode loop.
- `#[allow(clippy::too_many_arguments)]` on `spawn_pipewire` (8 params since the
KWin leg added `expect_exact_dims`; mirrors `from_virtual_output`).
clippy `-p pf-capture -p pf-vdisplay -p punktfunk-host --locked --features
nvenc,vulkan-encode -- -D warnings` is now green. (--all-targets additionally
trips a pre-existing env mismatch: the fedora libspa binding lacks
`SPA_VIDEO_TRANSFER_SMPTE2084`, referenced only by a `#[cfg(test)]` guard-test —
not a code issue; CI's pinned pipewire has it.)

A declared IddCx hardware cursor is IRREVOCABLE for its OS target's life
(§8.6), and the sticky exclusion survives monitor REMOVE→ADD because each
client gets a STABLE target id — so once any desktop-mode session declared,
every later pure-capture session on that target streamed a cursor-less
desktop: DWM excluded the pointer, no channel forwarded it, no blend drew it
(the exact no-regression gap §8.6's per-session cap gate cannot see).
Driver: track every successful SetupHardwareCursor per target
(DECLARED_TARGETS — scoped to the WUDFHost's life, exactly the sticky
state's scope) and report it in a new AddReply::cursor_excluded tail field
(dual-size discipline, both skews degrade cleanly; no proto bump).
Host: the flag rides AddedMonitor → Monitor → WinCaptureTarget; a session
WITHOUT the cursor channel on a flagged target forces composite mode in the
IDD-push capturer — GDI poller + blend for the session's life, pinned on
(set_cursor_forward cannot clear it: with no client drawing, un-compositing
would erase the pointer entirely).

gamescope excludes its pointer from the PipeWire node it feeds us and can't embed
one either (`set_hw_cursor` is inert), so every gamescope stream was cursorless.
Read the pointer from gamescope's nested Xwayland instead — XFixesGetCursorImage
for shape/hotspot/visibility, core QueryPointer for position — and publish a
CursorOverlay into the capturer's existing `cursor_live` slot, so the encoder
blend composites it into the video exactly like the SPA_META_Cursor path.
- pf-capture/src/linux/xfixes_cursor.rs (new): the XFixes reader. Connects to
EVERY nested Xwayland (Gaming Mode runs one per --xwayland-count) and follows
the focused one each tick (the display whose pointer moves), reading that
display's own cursor shape. Un-premultiplies ARGB -> straight RGBA. Drop stops
the thread.
- Capturer::attach_gamescope_cursor + the PortalCapturer override spawn it into
the same `cursor_live` slot; pf_vdisplay::gamescope_xwayland_cursor_targets
discovers the (DISPLAY, XAUTHORITY) pairs via the GAMESCOPE_WAYLAND_DISPLAY scan.
- host: SessionPlan.gamescope_cursor (set from the compositor at both resolve
sites AND on a mid-stream Desktop->Gaming switch); the blend gate now builds the
encoder blend for gamescope; a sibling composite arm attaches capturer.cursor()
per tick for capture-mode clients (no channel needed). native NV12 is disabled
for these sessions — that encode path can't blend the cursor (it assumes
gamescope embeds the pointer), so we capture RGB and route to the proven CUDA
VkSlotBlend / compute-CSC blend.
- the pipewire thread no longer clobbers `cursor_live` with None on a buffer that
carries no SPA_META_Cursor (gamescope) — that raced the XFixes writer and
strobed the composited pointer on/off.
On-glass (home-bazzite-2, RTX 5070 Ti, Gaming Mode): cursor visible + steady in
Big Picture and CS2 menus, follows focus between the two Xwaylands, hidden in-game.

Since the cursor-channel work, every Linux virtual output was created in
metadata pointer mode — making ALL sessions depend on host-side cursor
compositing, including the ones that can never use the channel (Moonlight/
GameStream, legacy clients, capture-mode starts). Those sessions paid the
blend bring-up per session and, whenever a visible cursor was composited,
the loss of NVENC's stream-ordered submit — for a strictly worse cursor
than the compositor's own.
Mirror the Windows no-regression gate: the already-wired per-session
set_hw_cursor(cursor_forward) now drives the Linux backends too. A
cursor-channel session gets metadata (shapes forwarded, composite flip
blends host-side — today's validated path, unchanged); every other session
gets the pointer compositor-EMBEDDED at creation (KWin zkde pointer=2,
Mutter cursor-mode=1, wlroots/hyprland portal CursorMode::Embedded — their
pre-channel default; the portal pair also gains the Metadata arm for
channel sessions, wired but untested on-glass). SessionPlan.cursor_blend
narrows to cursor-forward sessions and rides into the direct-SDK NVENC
open, which skips the Vulkan slot-blend bring-up entirely when off —
embedded sessions ring on plain CUDA surfaces and pay zero cursor cost,
per-session or per-frame.
The keep-alive registry's reuse key grows the created pointer mode (new
VirtualDisplay::hw_cursor getter): a kept embedded display has no cursor
metadata for a channel session to forward, and a kept metadata display
would leave a channel-less session with no pointer in its frames.

A vendored PTX blob is JIT'd against the driver's ISA ceiling, so the
cursor-blend module silently dies on drivers older than the generating
toolkit (CUDA_ERROR_UNSUPPORTED_PTX_VERSION/INVALID_PTX, 222/218 — the
KWin leg's invisible composite cursor on driver 595/CUDA 13.2 vs a
CUDA 13.3 blob). SPIR-V has no such coupling, and the in-tree precedent
already exists twice (vulkan_video's CSC blend, VkBridge's exportable
OPAQUE_FD → cuImportExternalMemory bridge).
New pf_zerocopy::vkslot::VkSlotBlend: the direct-SDK NVENC encoder now
allocates its input ring as exportable Vulkan buffers CUDA-imports (same
contiguous InputSurface layouts, pitch = row bytes rounded to 256), and
the cursor composite is a compute dispatch over the cursor's rectangle
(cursor_blend.comp, vendored .spv; spec-constant selects ARGB/NV12/YUV444;
BT.709 limited, matching the retired .cu). The surface SSBO is uint[] with
every invocation owning whole words — no 8-bit-storage device dependency.
Cursor-bearing frames force the existing CPU-synced submit path so the
CUDA copy → Vulkan dispatch (fence-waited) → NVENC encode ordering is
CPU-established; cursorless frames keep the stream-ordered fast path
untouched. Any bring-up/alloc/registration failure falls back wholesale
to plain pitched CUDA surfaces (never a mixed or short ring): sessions
always encode, composite mode just loses the cursor, warned once.
cursor_blend.cu / cursor_blend.ptx and the CursorBlend PTX loader are
deleted.

Rate-limited journal logging bracketing the silent segment of the Linux
composite path: what overlay (if any) the encode loop's composite arm
hands the encoder, and whether the NVENC cursor-blend kernel launches and
with what geometry. On-glass (KWin leg) the blend module loads yet the
composite cursor stays invisible — these two probes attribute it to
no-overlay / stripped-en-route / kernel-draws-nothing. The module-loaded
INFO line is permanent (success must be as attributable as failure);
everything else in this commit is temporary.

KWin's ScreenCastStream builds its PipeWire format offer — including the
maxFramerate cap it actively throttles delivery to — ONCE at stream
creation, when the virtual output sits at its hardcoded birth 60 Hz. A
kscreen custom-mode change afterwards updates the OUTPUT (readback says
240) but never the offer, so every consumer negotiates max=60 and the
stream delivers 60 (pw-dump-verified on KWin 6.6.4). The only path that
rebuilds the offer is the stream's own resize handling: a source SIZE
change while recording re-runs buildFormats — picking up the output's
current refresh — and renegotiates the live stream.
So above 60 Hz, birth the output at a sacrificial height (+16), then
install + select the real WxH@hz custom mode: the first frame recorded
after the consumer connects triggers KWin's resize path, which renegotiates
the live stream to WxH@hz. The capturer holds (requeues) buffers until the
negotiated size matches — new expect_exact_dims plumbing VirtualOutput →
registry (fresh creates only) → open_virtual_output → a self-disarming
gate in the process callback — bounded by a 3 s deadline that accepts the
producer's dims rather than wedging the session into the first-frame
retry loop. set_custom_refresh reads back the full active mode; a size
reject (pre-6.6 KWin) recreates plain at the real size @60.
Every kscreen operation now addresses the output by its NUMERIC id,
resolved by matching the managed name-prefix AND the just-created birth
size (newest id wins): a mode-switch supersede reuses the per-slot output
NAME (deliberately, for KWin's per-name config persistence) while the
superseded sibling is still alive, and name addressing hit the FIRST
match = the OLD output — on-glass that resized the live session's display
out from under it (wrong-res/black), read the old output back as 'mode
applied', and set the old output primary while the replacement starved at
its birth mode.

The vendored cursor_blend.ptx was regenerated with the CUDA 13.3 toolkit,
which stamps '.version 9.3' — and a driver whose JIT predates that ISA
refuses the whole module with CUDA_ERROR_UNSUPPORTED_PTX_VERSION (222),
silently killing host-side cursor compositing (on-glass: composite-mode
cursor invisible on driver 595.58, KWin leg). The kernels use only baseline
arithmetic, so hand-lower the version directive to 8.0 (CUDA 12.0), which
every supported Turing+ driver JITs. Both files now warn that an nvcc
regeneration re-stamps the version and must be re-lowered.

The frame-attached overlay is the pointer position at the last damage
frame; repeats re-encoding a static desktop froze the blended cursor
between redraws — on-glass the composite-mode cursor stuttered while
window drags (constant damage) were smooth. Refresh the repeat's overlay
from Capturer::cursor each tick so pointer-only motion re-blends at tick
rate — the bandwidth the pre-channel embedded mode already paid. Linux
only: the Windows capturer composites internally and its frames must
never carry an overlay a blend path would double-draw.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
The forwarder read only frame.cursor — the overlay attached to the LAST
EMITTED frame. Mutter's pointer-only buffers update the capture-side cursor
state but are skipped as frames, so between damage frames the forwarder
re-sent a stale snapshot: on-glass the client cursor appeared exactly when
clicking or crossing hover targets (damage) and froze/vanished otherwise —
the same pointer-only-motion gap the Windows IddCx channel fills, which is
why the encode tick already prefers the capturer's LIVE cursor. Publish the
overlay from every dequeued buffer (frames or not) into a shared slot and
implement the Capturer::cursor hook on PortalCapturer.
Host-composite mode on Linux still updates the blended pointer only on
damage frames (no re-encode of a static desktop on cursor motion) — the
regen-on-cursor-change the Windows path has is a follow-up.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Mutter only rewrites a buffer's SPA_META_Cursor region when the cursor
changed; recycled buffers between damage frames carry a stale id-0 meta.
Treating id 0 as a hidden pointer flickered the client cursor off between
hovers on-glass — per the SPA contract id 0 is 'invalid/no cursor info',
so keep the last-known state (OBS's consumer does the same). A genuinely
hidden pointer stops producing updates; the M3 relative-mode hint keeps
its Windows CURSOR_SUPPRESSED source.

Mutter offers SPA_META_Cursor with a FIXED size pod —
SPA_POD_Int(CURSOR_META_SIZE(384, 384)) in meta-screen-cast-stream-src.c —
while our request capped the range at meta_size(256, 256). The intersection
is empty, so the Meta param silently failed to negotiate and no buffer ever
carried the meta region: the entire Linux cursor pipeline (forward AND
blend) was blind on GNOME, proven by an on-glass probe counting 32k+
buffers with zero metas. KWin's offer fits inside 256², which is why the
same consumer code passed there. Raise the max to 1024² headroom (the
negotiated allocation follows the producer's value, not our max) and align
the bitmap parse guard.

The libei absolute device advertises one region per logical monitor, and
both MouseMoveAbs and touch mapped into regions().first() — whichever
output the compositor announced first. Next to a physical monitor (on-glass:
GNOME with a dummy HDMI beside the virtual primary) that put the pointer and
every click on the WRONG output: the seat cursor never entered the streamed
monitor, so neither embedded nor metadata cursor capture could ever see it,
and the cursor channel had nothing to forward. Pick the region whose logical
size matches the streamed mode (the wire flags already carry it); fall back
to first() for the single-monitor case. Region geometry now rides the
device-RESUMED log line for diagnosability; matching the screencast
mapping_id instead of the size is the follow-up for same-sized-monitor
ambiguity.

Same trap as the Mutter backend: zkde_screencast pointer mode 2 (embedded)
never delivers SPA_META_Cursor, starving both the cursor channel and the
encoder blend. Mode 4 (metadata) feeds both.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
The resize rebuild creates the new virtual display BEFORE retiring the old
one (create-before-drop), so the registry saw a live same-backend sibling —
its own dying predecessor — and told the backend it was not first in group.
Mutter then skipped the Primary/Exclusive apply ("joining an existing
display group — extending") and the retiring owner took the topology with
it: every resize silently demoted the virtual output to an extended,
shell-less desktop. Thread the superseded pool gen through acquire so the
replacement establishes topology, and stop counting kept (Lingering/Pinned)
entries as demoting siblings — no session owns them, so there is no live
desktop to clobber.

RecordVirtual was created with cursor-mode EMBEDDED, which never delivers
cursor metadata — the cursor channel had nothing to forward (client-drawn
cursor invisible) and the always-built encoder blend had nothing to
composite (host-drawn cursor invisible too). Metadata mode feeds both:
non-forwarding sessions get the blended pointer (same pixels Mutter would
have embedded), forwarding sessions strip the overlay and send shape/state.
The capturer already negotiates the meta on every stream (meta_param).

faad4b57 shipped the field, shader scale, and plumbing but the
scripted edit inserting the sdr_white_level_scale() refresh in the
scratch-rebuild arm matched nothing and silently no-op'd (no assert) —
sdr_white_scale stayed at its 1.0 init, i.e. 80 nits, i.e. exactly the
old dark cursor. Now queried on every scratch rebuild, with an info
log of queried/applied so an HDR session shows what it uses.

- The polled position is also the composite-blend position: at 16 ms a
240 fps session reused a stale position for ~4 consecutive frames and
the composited pointer visibly stuttered against the video. 4 ms
out-paces every session rate; a tick is one GetCursorInfo syscall.
- Log the queried DISPLAYCONFIG_SDR_WHITE_LEVEL scale on each blend-
scratch rebuild so an HDR session shows what is actually applied
(the virtual display's own SDR-brightness setting is the suspect
when the cursor still reads dark).

sRGB→linear alone lands cursor-white at 80 nits (scRGB 1.0) while DWM
composes the surrounding SDR desktop at the user's SDR-brightness
setting (~200+ nits by default) — the cursor read visibly dark on HDR.
Scale by DISPLAYCONFIG_SDR_WHITE_LEVEL (new
win_display::sdr_white_level_scale, queried on blend-scratch rebuilds —
the CCD query stays off the per-frame path).

Root cause, proven on-glass across five driver builds: a declared IddCx
hardware cursor is IRREVOCABLE. There is no un-declare DDI, the
empty-caps re-setup is rejected INVALID_PARAMETER, and after a
successful same-mode re-commit with the driver's re-declare provably
suppressed (sticky per-target flag, zero re-setups logged) DWM still
never composites the software cursor back into the monitor's frames.
Every DWM-based composite flip is therefore unfixable.
The composite (capture) model is now implemented in OUR pipeline:
- the driver keeps its hardware cursor declared for the session's whole
life (the state that works) — frames stay pointer-free always;
- in composite mode try_consume routes the conversion through a blend
scratch: slot copy + one alpha-blended quad of the GDI poller's shape
at its polled position (CursorBlendPass — fullscreen-triangle VS with
viewport placement, straight-alpha PS, sRGB→linear for FP16/HDR
rings), covering all four convert paths (NV12, 4:4:4 copy, P010,
PyroWave) GPU-side under the slot's keyed mutex;
- pointer-only motion produces no driver publish (declared hw cursor),
so try_consume REGENERATES from the last slot whenever the polled
cursor state changes — the cursor moves on a static desktop at tick
rate, without faking freshness for the stall/death watchdogs;
- set_cursor_forward becomes purely host-internal state; the
SET_CURSOR_FORWARD IOCTL machinery is no longer used by the host
(driver keeps it, dormant) and its sender plumbing is removed.

On-glass: 're-setup on swap-chain assign -> 0x0' fired AFTER 'enable=0
stored' — duplicate/successor monitor entries (re-arrival churn) kept
their default-true flag and re-declared the hardware cursor right after
the composite flip's re-commit, undoing it.
The desired state now lives in a per-target static
(CURSOR_FORWARD_DESIRED): every arrival inherits it (no generation can
resurrect a declare the session turned off), and the flip stamps EVERY
live entry matching the target, declaring against whichever has the
live worker.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
The empty-caps un-declare is REJECTED by IddCx (STATUS_INVALID_PARAMETER,
on-glass driver 9.9.0722.1407) — there is no un-declare DDI. The
composite flip now works with the only lever the OS gives us: every
mode COMMIT reverts the path to the software cursor, and the driver
skips its per-commit re-declare while cursor_forward_on is off. So:
- driver: disable stores the flag only (no DDI call); enable still
declares immediately against the live worker's event.
- host capturer: after a successful disable flip, force a same-mode
re-commit (win_display::force_mode_reenumeration) — DWM composites
the pointer from the very next commit; the swap-chain flap is the
class the driver's preserved-publisher machinery already rides out.
- state now survives re-arrivals end-to-end: the capturer caches the
APPLIED state (cleared on every channel (re)delivery, which
re-created driver entries need — their flag defaults to declared),
and the stream loop re-applies every tick instead of edge-gating
(steady-state cost: one Option compare).
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
On-glass (.173, match-window session): every window-size convergence
re-creates the driver-side monitor (re-arrival resize / sibling-session
slot churn), destroying the cursor worker the channel was delivered to —
the flip then died NOT_FOUND (no entry with target_id ∧ worker) and the
declared state was lost entirely.
Driver: set_cursor_forward becomes STATE, not an edge on one monitor
generation — find by target_id ∧ hw_cursor, store cursor_forward_on
even without a live worker (it steers the next delivery/re-setup);
declare/un-declare only when a worker exists. Channel delivery honors
the flag: setup_and_spawn(declare=false) adopts + spawns WITHOUT
declaring (composite mode), so a later enable-flip declares against the
worker's event.
Host: retain the SET_CURSOR_CHANNEL sender; extract
deliver_cursor_channel and RE-deliver the surviving section on every
ring recreate and — with one retry — when a flip IOCTL fails
(the re-arrived entry gets a fresh worker, declared per its flag).

Belongs to 493f4fae (which shipped only the crates/ side — this

PunktfunkConnection.setCursorRender(clientDraws:) over the new
punktfunk_connection_set_cursor_render export, driven by one
edge-detected reconciler in StreamView (clientDraws = captured &&
desktopMouse) called from every transition — the ⌃⌥⇧M chord,
engage/release, and session start. Capture model and released now get
the host-composited pointer back in the video (full fidelity); the
desktop model keeps the local NSCursor path. xcframework rebuilt v12.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
The cursor channel excluded the host pointer from the video for the
whole session, but the client only draws it under the DESKTOP mouse
model — flipping ⌃⌥⇧M to capture mid-stream left the session
pointer-blind (user-found). The fix makes render ownership LIVE state:
- wire: CursorRenderMode 0x51 (client→host, control stream) —
client_draws: true = desktop model (host excludes + forwards),
false = capture model / released (host composites, full fidelity —
DWM on Windows incl. real XOR inversion, encoder blend on Linux).
Sessions start client_draws=true (the pre-message behavior).
- host: control task stores the flag; the encode loop edge-detects it —
forwarding + frame.cursor strip while the client draws, quiet
forwarder + overlay-into-blend while composited. SessionPlan now
grants blend CAPABILITY wherever the capture has a pointer (dropping
the !cursor_forward gate) so the composite side needs no encoder
rebuild; per-tick frame.cursor decides what is drawn.
- Windows: Capturer::set_cursor_forward → retained
IOCTL_SET_CURSOR_FORWARD sender (proto v6) → driver (un)declares the
IddCx hardware cursor on the LIVE monitor. Un-declare re-issues the
setup with EMPTY caps (candidate mechanism — the DDI has no
documented un-setup); resetup-on-commit is skipped while off, so a
mode commit's software-cursor default is the fallback path. Failure
against a pre-v6 driver logs and keeps declared-at-ADD behavior.
- SDL client: one edge-detected reconciler at the cursor pump site —
desktop-active = client draws; capture model or released = host
composites. Covers the chord, the M3 auto-flip, and engage/release.
- C ABI v12: punktfunk_connection_set_cursor_render (additive; wire
version unchanged — pre-§8 hosts ignore the unknown message type).

cursorChannelActive/hostCursors/cursorState stayed latched across

The M2c redesign (design/remote-desktop-sweep.md §8): the IddCx hardware-
cursor query is alpha-only by design — IDDCX_CURSOR_SHAPE_TYPE has no
monochrome value, the OS pre-converts monochrome to masked-color, and
masked-color delivery is dead code on modern builds (proven on-glass at
every ColorXorCursorSupport level). The driver keeps its hardware cursor
declared (XOR FULL) purely so DWM excludes every cursor type from the
IDD frame; the SHAPE now comes from a GDI poller in the capture host —
which runs as SYSTEM inside the interactive session, so no helper
process is needed.
CursorPoller (idd_push/cursor_poll.rs, the RustDesk/WebRTC/OBS pattern):
~60 Hz GetCursorInfo on a dedicated thread; rasterise via
CopyIcon→GetIconInfo→GetDIBits only when the HCURSOR value changes;
monochrome via the WebRTC truth table with invert pixels as opaque black
plus a white outline; AND-mask alpha for alpha-less color cursors;
CURSOR_SUPPRESSED = hidden; per-output visibility via the target's
desktop rect; per-monitor-V2 DPI awareness thread-scoped; input-desktop
reattach on failure + 2 s cadence (GetCursorInfo on a stale desktop
succeeds with stale data). Spawned iff the cursor channel was delivered;
a live poller is the sole overlay source (no serial-namespace mixing) —
the driver shm read remains as fallback if the poller dies.
Not chosen: DXGI Desktop Duplication GetFramePointerShape —
PointerPosition.Visible goes stale under injected-only input on current
Win11 (Sunshine #5293, exactly our topology), it burns one of the
session's four duplication slots, and IDD-output metadata has
conflicting field reports.

Durable results of the M2c on-glass bring-up (.173, 2026-07-22):
- The base IddCxMonitorQueryHardwareCursor DDI slot is stubbed to
STATUS_NOT_SUPPORTED on WDK 26100 — add the ...QueryHardwareCursor3
wrapper (wdk-iddcx) and drain it instead; v3 X/Y are only meaningful
when PositionValid, so a position-invalid tick keeps the prior position.
- Hardware-cursor setup is per-mode-commit: the OS silently reverts to a
software cursor on every mode commit, so re-issue the setup on each
swap-chain assignment (monitor::resetup_cursor, called from
assign_swap_chain) or the query fails NOT_SUPPORTED forever.
- One caps definition for initial setup and re-setup, resting at XOR
FULL: the query delivers ONLY alpha shapes in every configuration
(all three ColorXorCursorSupport levels, event-driven and 30 Hz
polled) — masked/monochrome cursors never arrive. FULL keeps the
frame cursor-free for ALL cursor types; the full-fidelity shape comes
from the session-side cursor source in the host
(design/remote-desktop-sweep.md §8).
- Poll the query at ~30 Hz instead of pure event-wait: masked cursors
never fire the data event, and the seqlock's position/visibility
should stay fresh regardless.

On-glass (Mac ↔ Windows M2c host): the host cursor's VISIBILITY is not a
usable 'a game grabbed the mouse' signal — Windows hides the pointer for
ordinary desktop activity (clicking, typing). The per-frame forwarder
turned those transients into relative_hint=true, so the client flipped
desktop→capture→desktop, which (a) warped the cursor to view-centre and
(b) flushed held buttons via releaseAll — a spurious mouse-up ~200 ms
into every press that broke window dragging/resizing.
Disable the auto-flip; the mouse model stays user-driven (⌃⌥⇧M). The
hint still rides the wire, unused, for a future M3 that keys off a REAL
pointer-lock signal (host-side ClipCursor/raw-input detection) instead
of visibility.

The FIRST session's Welcome runs before any backend construction
(vdisplay::open happens at display prep, after the Welcome), so the
capability probe's vdm() expect panicked the very first handshake of a
fresh service — the client saw a dead connect and auto-wake kicked in.
init() is idempotent and the driver facade is a unit struct, so the

The Mac client now exercises the full cursor channel against capable
hosts: desktop-mode sessions advertise CLIENT_CAP_CURSOR, the host
stops compositing the pointer, and StreamView draws the forwarded
shapes as the real NSCursor — plus the M3 host-driven model flip.
- ABI v11: punktfunk_connect_ex9 (adds client_caps; ex7/ex8 pass 0 —
Android untouched), PunktfunkCursorShape/State + the two
next_cursor_* poll fns (audio-style borrow contract), and
PUNKTFUNK_CLIENT_CAP_CURSOR. Fixed in passing: the first insertion
split next_host_timing's cfg/no_mangle attributes off the fn, which
silently dropped the symbol from the header AND dylib — caught by
the Swift build, reattached with its docs.
- PunktfunkConnection: clientCaps connect param, hostSupportsCursor,
CursorShapeEvent/CursorStateEvent + nextCursorShape/nextCursorState
(one cursor thread drains both planes; cursorLock joins the close()
ladder).
- SessionModel: desktop-mode sessions (DefaultsKey.mouseMode) connect
with the cursor cap on macOS.
- StreamView: shape cache (serial → NSCursor, straight-alpha RGBA via
CGImage), resetCursorRects wears the HOST shape while the desktop
model is engaged (hidden host pointer ⇒ invisible), latest-wins
state pump, and the M3 auto-flip — edge-triggered on relative_hint,
⌃⌥⇧M sets an override latch cleared by the next host edge, leaving
relative warps the pointer to the host position via the inverse
letterbox mapping (CGWarpMouseCursorPosition, CursorCapture's
coordinate convention).
Verified: swift build + full test suites green (xcframework rebuilt at
ABI v11, signed); core 218 tests + clippy -D warnings on Linux (.21).

Brings the cursor channel to Windows hosts. The pf-vdisplay driver
declares an IddCx hardware cursor for sessions that negotiated
cursor-forward — DWM then EXCLUDES the pointer from the IDD frame and
delivers shape/position out-of-band, into the same CursorOverlay →
forwarder → wire → client pipeline the Linux portal path uses.
- pf-driver-proto v5 (additive, host floor stays 3): AddRequest's spare
tail becomes hw_cursor (same size/offsets); IOCTL_SET_CURSOR_CHANNEL
delivers a host-created CursorShm section (64-byte seqlock header +
256² shape buffer, layout pinned + tested). No event crosses the
boundary — the host polls at encode-tick pace.
- driver: wdk-iddcx grows the two cursor DDI wrappers; a per-monitor
cursor worker (event wait → QueryHardwareCursor → seqlock publish)
starts only when BOTH the ADD asked and the channel arrived, so a
failed delivery leaves DWM compositing as today. Shape bytes ship raw
(BGRA/masked + pitch); the host converts.
- host: the section rides the existing sealed-channel broker (least-
privilege dup, remote reap on failure); IddPushCapturer::cursor()
seqlock-reads → CursorOverlay (BGRA→RGBA, masked-color approximation,
desktop→frame origin shift, per-shape conversion cache). New
Capturer::cursor() trait hook — the encode loop prefers it over the
frame-attached overlay because hardware-cursor moves produce NO new
frame on a static desktop. hw_cursor survives the re-arrival resize
(carried on the manager's Monitor).
- negotiation: cursor_forward grows the Windows arm (client cap ∧
driver proto ≥ 5, probed once via the control device); SessionPlan
carries cursor_forward → OutputFormat.hw_cursor.
- drive-by: wdk-probe's two pre-existing same-type casts (clippy) and
pf-vdisplay's stale spike-test refs (crate::win_display moved to
pf-win-display; tracing-subscriber was never a dep) repaired.
Verified: proto tests on Mac AND MSVC (15/15 incl. the CursorShm
layout pin); clippy -D warnings for proto/frame/capture/vdisplay/host
on Linux (.21) and native Windows (.173); the DRIVER workspace clippy
-D warnings green against the real WDK 10.0.26100 bindgen (DDI names,
enum variants and IDARG layouts all bind). On-box driver deploy +
on-glass validation follow.

The full Parsec model: launching a game from a desktop session flips the
client into captured relative automatically, and back — no chords.
- Capture overlay now distinguishes 'hidden' from 'no cursor yet':
CursorOverlay grows a visible flag, overlay() returns Some whenever a
bitmap is known (the encode loop strips invisible overlays after
forwarding so no blend path ever draws one; the CPU composite guarded
on visibility already).
- Host forwarder maps it onto the reserved wire bit: visible ⇒ VISIBLE,
hidden-but-known ⇒ RELATIVE_HINT (an app grabbed/hid the pointer),
never any hint before the first bitmap — a cold start can't flip a
desktop session into capture.
- Presenter: edge-triggered auto-flip on hint changes via the new
Capture::set_desktop (chord semantics untouched); a manual ⌃⌥⇧M sets
an override latch that holds until the HOST's intent next changes, so
the hint never fights the user. Leaving relative warps the local
cursor to the host's last pointer position through the new
content_to_window inverse-letterbox mapping (unit-tested against
finger_to_content) — the hand-back is seamless.
Verified on .21: fmt + clippy -D warnings + tests (presenter 20 incl.
the inverse-mapping roundtrip, host 245).

The host cursor stops riding the video and becomes a real OS cursor on
the client (the Parsec/RDP model): pointer feel no longer pays the
capture→encode→network→decode→present round trip.
Wire (M2a):
- Hello grows a client_caps trailing byte (CLIENT_CAP_CURSOR) after the
fixed display_hdr block — presence disambiguated by remaining length,
which caps the post-HDR tail at 27 bytes (documented); Welcome answers
HOST_CAP_CURSOR (capable-and-asked, the 444/clipboard precedent).
- CursorShape (0x50, control stream): serial + dims + hotspot + straight
RGBA, ≤120px/side so the u16 frame always fits (128² would overshoot);
client caches by serial — re-showing a known shape costs 14 bytes, not
a bitmap (RDP pointer-cache for free).
- CursorState (0xD0 datagram): serial + visible/relative_hint flags +
position, sent once per encode-loop tick — latest-wins, self-healing
under loss, no refresh timer. relative_hint is reserved for M3.
- Client core: two new planes (control-task + datagram-task arms) →
next_cursor_shape/next_cursor_state; connect() grows client_caps
(C ABI passes 0 until the v11 cursor poll fns exist).
Host (M2b, Linux portal only):
- handshake::cursor_forward is THE predicate (client asked ∧ Linux ∧
compositor ≠ gamescope) — Welcome bit and session wiring both read it.
- SessionPlan.cursor_blend goes false for a forwarding session; the
encode loop ticks a CursorForwarder every iteration: shape-serial diff
→ control-task bridge (mirrors probe_result), state datagram → conn.
- CursorOverlay/capture CursorState carry the hotspot through
(nearest-neighbor downscale backstop for XL cursors, unit-tested).
Presenter:
- CursorChannel drains both planes per loop iteration; shapes become
SDL color cursors (from_surface + hotspot), applied while the desktop
mouse model is engaged; visibility follows the host; capture/released
hands back the system cursor. Sessions advertise the cap when they
START in desktop mode.
Verified on .21: fmt + clippy -D warnings (7 crates) + tests green
(core 218 incl. new wire roundtrips, host 245 incl. e2e + forwarder
downscale tests).

Folds the parked client-side-cursor machinery (cursorMode auto/always/
never, hidden while disabled) into the cross-client mouse model:
MouseInputMode capture|desktop under DefaultsKey.mouseMode, picked in
Settings ▸ Keyboard & mouse (macOS), resolved at session start and
gated off on gamescope hosts (relative-only EIS).
Desktop model = the un-neutered absolute path with the SDL cursor
policy: pointer never disassociated (enters/leaves the stream freely),
monitor forwards letterboxed absolute positions, and the local cursor
hides only while over the view via an invisible-cursor rect (the
host's composited cursor is the one you see; AppKit manages the rect,
so no hide/unhide balancing). ⌘⇧C becomes ⌃⌥⇧M — the same chord as
the SDL clients — flipping the model live with an atomic
release/re-engage.
Verified: swift build + full test suites green (macOS arm64).

New physical-mouse model beside capture: Desktop leaves the pointer
uncaptured and sends absolute positions through the letterbox
(MouseMoveAbs — every host injector already consumes it). Capture
stays the default and the game model.
- pf-client-core: MouseMode (capture|desktop) persisted in Settings,
default capture so existing stores are unchanged.
- pf-presenter: Capture grows a desktop model — latest-wins pending
abs position coalesced per loop iteration (same 1000 Hz discipline
as relative), flushed before clicks/keys/wheel so they land where
the cursor is; Ctrl+Alt+Shift+M flips the model live; local cursor
stays hidden over the window (the host's composited cursor is the
one you see until the M2 cursor channel); Windows keyboard grab
only engages for capture (a desktop stream is something you
Alt-Tab away from).
- gamescope gating: its EIS is relative-only, so desktop mode is
pinned off there (resolved_compositor), with a log note.
- Settings surfaces: GTK row (dynamic caption), WinUI combo,
console-UI row + step test, capture-hint line.
Verified: fmt + clippy -D warnings + tests (33/40/19) on Linux .21;
clippy -D warnings for all five crates incl. punktfunk-client-windows
native on .173.

The 0.17.2 placeholder underestimated this cycle: Android mouse & keyboard
(physical mouse + capture, TV remote-as-pointer, IME text, clipboard), the new
committed-text input plane (InputKind::TextInput / HOST_CAP_TEXT_INPUT), and
the ChaCha20-Poly1305 session cipher are feature work — a minor, not a patch.
Wire/driver/C-ABI markers all unchanged (2 / 4 / 10): every addition is

The android leg failed twice on 2026-07-22 with sdkmanager's "Error on
ZipFile unknown archive" — once in our NDK/build-tools step, once inside
setup-android's default package set. Root cause is the shared runner fleet
dropping packets under parallel-job load (the same class retry.sh documents
for the flatpak leg): sdkmanager unzips while streaming, so a truncated
stream reads as a corrupt archive. A solo re-download on the same runner
verified clean.
- setup-android: install only platform-tools — the action's default legacy
`tools` package drags in the ~250 MB emulator this job never uses, which
was the largest and flakiest download in the whole leg.
- NDK/build-tools/CMake: wrap sdkmanager in retry.sh (4 attempts, linear
backoff) — a failed attempt leaves no partial package, so re-invoking is
safe.

punktfunk negotiates HDR correctly (the stream is BT.2020 PQ 10-bit) but never
told the client to switch its display into HDR picture mode, so HDR streams
stayed in SDR on the TV. Sunshine sends an async control-stream message
(IDX_HDR_MODE, type 0x010e, carrying SS_HDR_METADATA) shortly after the stream
starts; Moonlight only flips the TV into HDR on that cue. We sent exactly one
host→client control message (rumble 0x010B) and never this one. (aurora-tv PR
#53 worked around it client-side by inferring HDR from the negotiated format;
this fixes it host-side so stock Moonlight clients switch too.)
Once the control stream is live and the session negotiated HDR, send a one-shot
0x010e message (enable + 26-byte SS_HDR_METADATA from generic HDR10 defaults),
latched per connection and re-armed on Disconnect. The rumble sequence counter
is unified into a single monotonic `host_seq` shared by both message types —
the GCM nonce derives from `seq`, so a separate per-type counter would reuse
(key, nonce) pairs in the host direction.
The BT.2020 PQ VUI already rides the bitstream (the encoder derives it from the
P010 capture format), so this is purely the missing "switch now" signal; no
encoder change needed. Wire layout locked by unit tests.

rustls-webpki 0.103 accepts only X.509 v3 certs and returns
`UnsupportedCertVersion` for anything older, aborting the mTLS handshake at
the `CertificateVerify` step before it ever checks the signature. The
moonlight-embedded client family (moonlight-embedded, aurora-tv, …) still mint
self-signed **v2** certs with no keyUsage extension, so pairing fails against
punktfunk while it works against Sunshine — whose OpenSSL verify callback never
inspects the cert version. (aurora-tv PR #53 worked around this client-side by
switching to v3 + keyUsage; this fixes it host-side for stock clients too.)
The cert's X.509 version and extensions carry no security weight here: the
client cert is self-signed and pinned by SHA-256 (`peer_is_paired`), and the PIN
pairing ceremony is the real proof of identity. The property that DOES matter —
that the peer holds the private key for the cert it presented — is still
enforced: when webpki rejects the cert we re-run exactly that `CertificateVerify`
check with a version-agnostic parser (x509-parser SPKI + the same `rsa` verify
`pairing::verify256` uses). This is a full cryptographic check, never a bypass:
a bad signature still fails, and non-RSA / unsupported schemes fall through to
webpki's original error. Matches Sunshine's leniency without loosening the
pinned trust model.

The desktop clients' clipboard protocol, adopted on Android (text-only v1):
opt-in ClipControl at stream start when the host advertises HOST_CAP_CLIPBOARD
and the new "Shared clipboard" setting (default on) allows.
Device → host: local copies (primary-clip listener + a probe at start) are
announced as lazy format-list offers; the text crosses only when the host
actually pastes (FetchRequest → served from the live clipboard). Host →
device: a host copy's offer is fetched eagerly and lands in the system
clipboard (Android has no practical lazy-paste provider), with an echo guard
so the resulting clip-changed callback doesn't bounce it back as a new offer.
Native side: session/clipboard.rs JNI shims over NativeClient's clip_*
surface; events cross to Kotlin as compact strings from a blocking
nativeNextClip poll on a dedicated thread (the nativeNextRumble pattern),
joined before the session handle is freed.

The VK key-event vocabulary cannot express text an input method COMMITS
(autocorrect, gesture typing, non-Latin scripts, emoji). Add a first-class
text event and negotiate it:
- punktfunk-core: InputKind::TextInput (= 15) carries one Unicode scalar per
event in `code`; HOST_CAP_TEXT_INPUT (0x04) in Welcome::host_caps.
- Host advertises the cap only where the session's inject backend can type
text: Windows SendInput (KEYEVENTF_UNICODE, surrogate-pair aware) and the
Linux wlroots backend — a dedicated second zwp_virtual_keyboard whose xkb
keymap grows Unicode keysyms on demand (the wtype model), so keymap
re-uploads never disturb the main device's layout/modifier state. The
KWin-fake-input/libei/gamescope backends can only press layout keycodes, so
those sessions don't set the bit and clients keep the VK fallback.
- GameStream plane: Moonlight's UTF-8 text packet (MAGIC_UTF8, previously
recognized-and-dropped) now decodes to the same TextInput events.
- Android: KeyCaptureView picks a real editable InputConnection when the host
has the cap — the IME runs its full machinery, mirrored to the host live via
common-prefix diffs of the composition (backspaces + new suffix), with
setComposingRegion adopting committed text so autocorrect-revert flows diff
instead of retyping; newline→Enter, deleteSurroundingText→Backspace/Delete.
Older hosts keep the TYPE_NULL raw-key path unchanged.
- keymap: media VKs (0xB0-0xB3) → evdev so the Android media keys land on
Linux hosts too.
Verified: punktfunk-core + host gamestream + pf-inject tests green on Linux
(Ubuntu box), clippy clean; Android app+native builds.

Phase A — hardware mouse: new MouseForwarder routes every SOURCE_MOUSE event
while streaming. Uncaptured (default): hover/drag positions forward as absolute
cursor moves, wheel with fractional accumulation (high-res wheels), all five
buttons incl. back/forward as X1/X2; the local cursor is hidden over the stream
(TYPE_NULL pointer icon) so the host's composited cursor is the visible one.
Captured ("Capture pointer for games" setting, or Ctrl+Alt+Shift+Q live): the
OS pointer is grabbed via requestPointerCapture on the (repurposed) key-capture
view and raw relative deltas forward as mouse-look; held buttons are tracked
and flushed on capture loss/teardown, and the engaging click is swallowed
(desktop parity). Mouse clicks are intercepted before Compose so they can never
be misread as trackpad taps; a mouse back-button's FALLBACK BACK is dropped so
it can't yank the user out of the stream.
Phase B — keyboard: media/consumer keys (play/pause/next/prev/stop) now map to
their VKs instead of falling to the system; TV-remote SELECT maps to Enter.
Phase D — Android TV: RemotePointer turns a D-pad-only remote into a pointer
(Siri-remote analogue): hold SELECT ~0.8s toggles, D-pad glides the host cursor
with ramped acceleration (Choreographer-paced, diagonal-normalized), SELECT
taps click, play/pause right-clicks, holding it toggles the on-screen keyboard,
BACK leaves pointer mode; an overlay hint teaches the vocabulary.
Settings: "Capture pointer for games" + "Invert scroll direction" (applies
to the wheel and two-finger touch scrolling).

Field report: with Exclusive Topology, the physical monitor sometimes stayed
lit — every isolate attempt re-committed and failed SetDisplayConfig with
0x57 ERROR_INVALID_PARAMETER. Clearing DISPLAYCONFIG_PATH_ACTIVE alone leaves
the deactivated path's source/target modeInfoIdx pinned to the queried mode
entries, and per the SetDisplayConfig contract a path being turned off must
have BOTH mode indexes set to DISPLAYCONFIG_PATH_MODE_IDX_INVALID; some
driver/topology combinations (notably when the doomed path shares a source
with the kept virtual path) reject the supplied config outright, so the
retry loop could never converge.

Remote INPUT resets the compositor's idle timers, but a passive
(video-only) viewer sends none — observed live: a SteamOS Game-Mode
host s2idled mid-day and dropped off the network (in a VM with GPU
passthrough it never woke again). Refcounted across planes: the native
LiveSessionGuard and the GameStream video worker each hold a share;
first hold takes the logind sleep:idle block inhibitor on a dedicated
plain thread (zbus blocking must not run on a tokio worker), last drop
releases. Best-effort: no logind → warn once and stream on. No-op off
Linux (macOS/Windows manage their own assertions).

- rebuild-check.sh + punktfunk-rebuild-check.service (enabled, ordered
Before=punktfunk-host): ldd-probes the host binary at session start —
milliseconds when healthy, a full update.sh rebuild only when a
SteamOS update actually broke its library links. update.sh restarts
go --no-block so the check → update.sh → restart chain can't deadlock

- installer summary: web console is https (the unit serves TLS).

touch = single-finger pointer, exact taps, no multi-touch),

The raw-client-pixels fallback is exact only while the managed session
runs at the client's mode. When they diverge — foreign-gamescope
attach at its own resolution, supersample/under-render, transitions —
raw pixels drift or land out of range. The EIS relay file now carries
the session's current output size as a second "WxH" line (from
current_gamescope_output_size()); the injector scales normalized
client positions into it, keeping raw pixels only as the last resort.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
The previous commit's no-region fallback never fired: gamescope DOES
advertise a region — (0,0,INT32_MAX,INT32_MAX), meaning "coordinates
are raw". Mapping normalized positions into it explodes a center tap
to x≈1e9, clamped by gamescope to the far corner — the cursor pinned
at (1279,799) and every degraded-touch tap landing there. Treat a
region as an output geometry only when plausibly sized (≤16384 px);
otherwise emit raw client pixels.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
gamescope's "Gamescope Virtual Input" advertises pointer_abs but no
region, so every MouseMoveAbs (and the degraded-touch moves built on
it) was silently dropped (emitted=false) — clicks then landed at a
stale cursor position. With no region, the managed session runs at the
client's mode, so client pixels are output pixels: emit them raw.
Also: log region count/dims at device-resume, and add
PUNKTFUNK_INPUT_TEST_ABS=WxH to `input-test` (corners + center, 1s
apart) so the degraded-touch path is verifiable with xdotool alone.

gamescope's EIS ("Gamescope Virtual Input") advertises pointer/
pointer_abs/button but never a touchscreen — so in Game Mode every
remote TouchDown/Move/Up was dropped on the floor (Desktop Mode works
via KwinFakeInput, which does touch). Headless KWin's libei has the
same gap. Instead of dropping: degrade to a single-finger absolute
pointer — down = abs-move + left press, move = abs-move, up = release —
synthesized through the normal Mouse* inject paths so region mapping,
held-state tracking, and release_all apply. First finger drives the
pointer; later fingers are ignored (a pinch degrades to a drag). A
touchscreen device appearing later takes over on the next touch —
checked per event, never latched.

Verified live on a SteamOS 3.8.14→3.8.16 update: the A/B partset switch
rebuilds /etc and drops everything not on Valve's keep list — the udev
rule (uhid access: virtual pads silently degrade to Xbox 360), the
vhci-hcd autoload (native Deck pad transport), and the UDP buffer sysctl
(back to 208 KB → stutter). Valve's sanctioned extension point is a
drop-in under /etc/atomic-update.conf.d/ — itself on the stock keep
list, so it self-preserves. install.sh §4 and update.sh now register
scripts/punktfunk-atomic-keep.conf there.

- scripts/steamdeck/install.sh (§2b) + update.sh: build and install the
scripting runner user-scoped (~/.local wrapper + pinned bun + bundle) —
SteamOS's read-only /usr can't take the .deb layout, so the console's
plugin store reported "the plugin runner isn't installed" on every
SteamOS host. update.sh retrofits it onto existing installs.
- plugins.rs runner discovery: check the ~/.local layout after the /usr
ones; mention the SteamOS path in the not-installed error.
- update.sh: define warn() — it was used but never defined, so under
`set -e` the first warn aborted the update before services restarted.
- pf-client-core gamepad: a Steam Input virtual pad forwarded on a real
Deck (the only-pad case) now declares the DECK kind in its per-pad
arrival instead of the wrapper's Xbox 360 identity — the session-level
auto_pref already resolved SteamDeck, but the arrival overrides it on
current hosts.
- reject tests: cover SetupFailed; move the foreign-code probe off 0x68.

Three fixes for the "most connects simply fail" trap on a SteamOS host
with no physical display (VM testbox, panel-less mini PC):
- restore path: skip the restore-to-physical-panel when no DRM connector
reports a connected display — removing the headless drop-in and
restarting gamescope-session.target on such a box just crash-loops
gamescope and strands every later connect on "no usable compositor".
Keep the headless session (and the takeover state) instead.
- connect path: when no live graphical session exists but the MANAGED
gamescope infra is present (SteamOS gamescope-session / Bazzite
session-plus), route to the gamescope takeover — which rebuilds the
session at the client's mode — instead of failing the connect.
- error delivery: a session-setup failure used to just drop the QUIC
connection, reaching the client as "control stream finished mid-frame"
(indistinguishable from transport trouble). Close with a typed
setup-failed code (0x68, RejectedSetupFailed = -29) carrying the error
text, and give the client handshake/pairing error paths a short grace
for the CONNECTION_CLOSE to beat the stream error it caused.

pyrowave-sys's build.rs runs cmake to build the vendored PyroWave C library,
but cmake wasn't in the distrobox apt list — so `cargo build -p punktfunk-host`
dies on every SteamOS host with "is cmake not installed?". Add it.
Also move sudo acquisition from step 4 (after the ~15-min build) into preflight
and keep the timestamp warm across the build. Before, a non-interactive run
(`ssh host 'bash install.sh'`) silently skipped the UDP-buffer/udev/vhci-hcd/
input-group tuning AND enable-linger — a "successful" host with no gamepad
passthrough, lossy streaming, and no headless persistence (dies on logout).
Now sudo is prompted once up front (authorize and walk away), and a no-TTY /
no-password run fails loudly before the build instead of silently at the end.
Validated end-to-end on SteamOS 3.8 in a VM with Radeon 780M passthrough:
full host + web build, all planes listening, VAAPI render node, headless
auto-start via linger.

Lifts the ~100 Mbps decrypt ceiling on clients without hardware AES — the
armv7 soft-AES targets (webOS TVs), where AES-128-GCM resolves to fixsliced
software AES + software GHASH (~50-100 cpb) while ChaCha20-Poly1305's ARX
construction runs ~10-17 cpb portable, a 4-7x lift that PyroWave-on-TV needs
(design/chacha20-session-cipher.md).
Phase 1 (core crypto, no wire change): SessionKey merges cipher choice and
key material (invalid combinations unrepresentable, zeroize + redacted-Debug
discipline kept); SessionCrypto dispatches both aead-0.5 ciphers per call —
the salt||seq nonce scheme, per-direction salts, seq-as-AAD and replay
window carry over verbatim (same 96-bit nonce / 16-byte tag, const-asserted).
Config.key becomes SessionKey; validate's zero-key rejection follows the
active variant. The C ABI keeps its fixed 16-byte key mapped to AES — no
ABI_VERSION bump.
Phase 2 (negotiation): VIDEO_CAP_CHACHA20 (0x40) — support-plus-request in
one bit, the VIDEO_CAP_444 precedent. Welcome grows cipher@68 +
key_chacha@69..101, emitted only when non-zero so an AES session's Welcome
stays byte-identical to the pre-cipher form; decode is fail-closed (short
key or unknown id -> Err, never a silent AES fallback). No WIRE_VERSION
bump; downgrade resistance inherited from the pinned-TLS control channel.
Phase 3 (host): grant only when the client advertised the bit and the
PUNKTFUNK_CHACHA20 kill-switch (default on, documented) allows; fresh
32-byte per-session key from the same RNG discipline, legacy key field
stays independently random; resolved cipher logged at session start.
Verification: seal/open suites parameterized over both ciphers + a
cross-cipher tamper case; Welcome roundtrip/truncation/fail-closed tests;
ChaCha lossy-loopback soak (loss/replay is cipher-independent); bench
gains _chacha20 series (AES ids unchanged for CI history) — host-side
sealing line-rate-trivial on both x86 (~640 MiB/s) and Apple Silicon
(~535 MiB/s). punktfunk-probe drives the interop matrix via
PUNKTFUNK_CLIENT_CHACHA20=1 and logs the negotiated cipher.
Phase 4 (pf-webos pin bump + unconditional cap bit) follows the next
core release.

The CI workflow assembled the store zip by hand and silently drifted from
scripts/package.sh when 60d46530 added assets/ and controller_config/ — every
published build (canary and stable through 0.17.1) was missing both, so the
Steam shortcut a fresh install creates had no images and no controller layout
(shortcut_art() found nothing to send; apply_controller_config failed with
template-missing). CI now stages through scripts/package.sh — the plugin file
list lives in one place — and a backstop verifies the runtime-loaded pieces are
in the zip before publishing.
Frontend hardening for installs poisoned by those builds: applyArtwork stamped
its per-appId ART_VERSION marker even when zero assets were applied, so
shipping the files alone would never heal existing shortcuts — only mark done
when something actually landed, and bump ART_VERSION 2→3 to force one re-apply.
Same guard for the controller-config marker (ok with zero account configset
dirs is not done), plus one deferred artwork retry for the fresh-AddShortcut
registration race setShortcutHidden already defers around.

The PUNKTFUNK_PIN_CLOCKS clock pin (AMD power_dpm_force_performance_level=high / NVIDIA nvmlDeviceSetGpuLockedClocks) was armed once at host start and released only at host exit, so the box's clocks stayed pinned the whole time the host ran — even with no client connected.
Move the pin behind a box-wide refcount (gpuclocks::session_pin()) shared across both streaming planes (native + GameStream): it arms on the first live client and releases on the last disconnect. on_host_start() now only installs the process-scoped NVIDIA P2-cap application profile. No behavior change when PUNKTFUNK_PIN_CLOCKS is unset.

Launching from the Decky plugin against a sleeping host fired the
Wake-on-LAN packet and dialed immediately — but the dial was a single
quinn attempt that gave up after the transport's 8 s idle window, far
shorter than a suspend-to-RAM resume. The host woke to find the client
already gone (its retransmitted Initials show up host-side as
"QUIC accept failed error=timed out"), the stream shortcut exited, and
the launch looked cancelled.
- punktfunk-core: dial in a loop until the embedder's connect budget is
spent — short 3 s attempts keep the Initial cadence dense, so the
connect lands within ~a second of the host's network returning. Only
silence is retried: pin mismatches, typed rejections, and any real
answer surface immediately, and the shutdown flag stops the loop.
- decky: stretch the budget to 75 s when a magic packet actually went
out (PF_CONNECT_TIMEOUT → --connect-timeout via the wrapper), so the
retry window covers the resume; an awake host still connects in <1 s.
- host: a clean close before the control handshake is a reachability
probe (hosts-page online pips), not a failed session — log it at
debug instead of WARN "session ended with error", which buried the
real failures in the reporter's log.

The system-tuning block (UDP buffers, gamepad udev rule, vhci-hcd autoload,
input group) was gated on `sudo -n true` — passwordless sudo — so on a stock
SteamOS box (the deck account needs a password) the whole block was silently
skipped: /dev/uhid stayed root-only so the gamepad degraded to an Xbox 360 pad,
and the UDP buffers stayed at the 416 KB default. Video was unaffected because
Game Mode/gamescope needs none of it, which masked the skip on-glass.
- install.sh + update.sh: acquire sudo interactively (`sudo -v` prompt on a TTY)
instead of requiring passwordless; skip only when there's no TTY or auth fails,
and then print the exact manual block plus a `passwd` hint — a stock SteamOS
'deck' account has no password, so sudo can't work until one is set.
- update.sh: also retrofit the UDP-buffer sysctl for older/skipped installs, and
loudly nag to reboot when the input group was just added (a --user restart does
not pick up the new group; only a fresh login does).
- steamos-host.md: note this step prompts for the sudo password.
Root is unavoidable: the udev rule, input group, and vhci-hcd module are all
kernel operations with no user-space alternative.

A fresh SteamOS host install failed on-glass two ways: KWin denied Desktop-mode
capture (zkde_screencast_unstable_v1) so every session died in the pipeline build,
and the native Steam Deck pad degraded to an Xbox 360 controller. Both stem from
setup that only a fresh login applies — the host user-service keeps the
pre-install group set and KWin reads its .desktop grant at session start — plus a
missing vhci-hcd autoload the pad's USB/IP transport needs (the deb/rpm/arch
packages ship it; the Deck installer did not).
- install.sh: install punktfunk-modules.conf (+ modprobe vhci-hcd now) for the
native Deck controller transport, seed the KDE RemoteDesktop grant
(kde-authorized) for Desktop-mode input, and print a loud "reboot before
streaming" notice when a relogin is actually required (input group added or the
.desktop grant first installed).
- update.sh: retrofit the udev rule, vhci-hcd autoload, input group, and grant so
existing installs pick them up on the next update without a reinstall.
- steamos-host.md: document the first-install reboot and the native controller
passthrough requirements (input group + vhci-hcd + client-side Steam Input Off).

The VirtualHere DualSense recipe linked the `virtualhere-dualsense.ts` SDK
example as a deployable recipe but skipped everything needed to run it: that
VirtualHere is a server (couch) + client (host) pair, and that the example —
like every example — imports `../src/index.js`, which only resolves inside the
SDK repo. A user copying it out had no way to know they must
`bun add @punktfunk/host` and swap that import.
- automation.md: rewrite the recipe into a full walkthrough — the two-sided
VirtualHere setup, the `-t` verbs, the zero-code hooks version, and a new
scripted section with exact deploy steps, env vars, and running it as a
service (its own SIGTERM handler makes `systemctl stop` release the pad).
- sdk/README.md: say how to run an example in-repo vs deployed on a host.
- virtualhere-dualsense.ts: header note on the import swap + service setup,
since that file is where the doc link lands.

Task 1 (latency): the transactional present now commits from the RENDER
thread inside an explicit CATransaction + flush() instead of hopping to
main. The present harness (2026-07-21, 240 Hz Studio, full-size window)
measured the main hop batching presents at runloop-iteration rate when
main is busy — an active implicit transaction NESTS the explicit one —
which is the field's presents=55 @ fps=240 / display_p50 18.6 ms.
Off-main commits measured immune to main churn: glass p50 ~10 ms,
cadence a clean 4.17 ms at 240. flush() is load-bearing: without it the
render thread's own implicit transaction (drawableSize/colour writes)
swallows the explicit commit and NOTHING reaches glass — the harness
reproduced the exact freeze (every present dropped). Legacy main-hop
kept as PUNKTFUNK_TXN_PRESENT=main for field A/B. New pf-windowed
Console line (subsystem io.unom.punktfunk, category presenter)
decomposes the issue side per second.
Task 1 lever D: the f407f418 IOSurface contents-swap path is
resurrected format-aware as WindowedPresentMode.surface — bgra8 SDR /
rgba16Float+PQ-tagged HDR pool, swap committed off-main from the
completion handler; EDR anchored by the metal layer underneath.
Env-only prototype (PUNKTFUNK_WINDOWED_PRESENT=surface) until the HDR
composite is eyeballed on glass.
Task 2 (setting): punktfunk.windowedSafePresent (default ON =
transactional mitigation; OFF = the fast async path whose panic the
saga is about — the caption says so in plain words). Rows in the touch
Settings (Presentation) and gamepad settings, macOS-only.
PUNKTFUNK_WINDOWED_PRESENT=async|transaction|surface overrides for dev
A/B. maximumDrawableCount stays 3 — the harness measured 2 starving the
render loop (172/s) and worsening glass p50.

Swift `Int` is 64-bit (Foundation infers %lld); the stats mirror's format
string used %d (32-bit C int) for fps/presents/lost. macOS 26's strict
String(format:) validator rejects the mismatch and drops the whole line
(the error also cascades onto the float args, mis-blaming floor_p50). Use
%lld for the three Int fields. Pre-existing, unrelated to the DCP work;
surfaced while reading presenter logs during the panic fix.

The windowed-macOS "mismatched swapID's" @UnifiedPipeline.cpp kernel
panic is the CAMetalLayer ASYNC image queue (commandBuffer.present,
mandatory with displaySyncEnabled=false) diverging from WindowServer's
compositor on a high-refresh composited session — it survived glass
pacing (PyroWave, 2026-07-18) and hit windowed HEVC on the same 240 Hz
Mac Studio (2026-07-21), so it's the async queue itself, at any codec
or pacing.
f407f418's mitigation routed windowed PyroWave through a BGRA8 IOSurface
layer.contents pool, which cannot carry HDR — extending it to HEVC would
have tone-mapped windowed HDR down to SDR. Instead, present the drawable
through a Core Animation transaction (CAMetalLayer.presentsWithTransaction)
for every windowed session: commit, waitUntilScheduled, then drawable.present()
inside a CATransaction, so the swap commits with the layer tree and stays
in lockstep with the compositor instead of racing it. The full
rgba16Float / PQ / EDR render path is untouched — windowed HDR is real
HDR again. Fullscreen keeps the async path (direct scanout, lowest latency,
no panic there).
Removes the IOSurface surface pool, its surfaceLayer sibling, and the
macOS windowed PQ->SDR tone-map (tvOS keeps its no-headroom tone-map).
Net -150 lines. swift build + 169 tests green. Needs on-glass soak on
the 240 Hz Mac Studio (kernel race — only real hardware confirms).

Flip both zero-copy levers from opt-in to default:
- The capture negotiation now PREFERS gamescope's producer-side NV12 pod by
default (PUNKTFUNK_PIPEWIRE_NV12=0 restores the packed-RGB negotiation).
Codec-aware gating rides a new OutputFormat::nv12_native ->
ZeroCopyPolicy::native_nv12_session edge resolved by the host facade from
the session plan (pf_encode::linux_native_nv12_ok): only H265/AV1 sessions
whose backend can open the raw Vulkan Video encoder ever see the NV12 pod
-- an H264/Moonlight session (libav VAAPI, which would misread the
two-plane buffer) keeps today's BGRx negotiation, as do the
GameStream-resolve and portal-mirror paths, PyroWave, and NVENC prefs.
- RGB-direct's unaligned modes default to the true-extent direct import
(PUNKTFUNK_VULKAN_RGB_TRUE_EXTENT=0 restores the padded-copy staging).
Guarded-tested on Van Gogh with the kernel journal watched: clean, and at
5.38 ms p50 the fastest 1080p encode path measured on that hardware. The
EFC only exists on Mesa >= 26, where the codedExtent-driven session_init
padding is guaranteed (verified back to Mesa 24.2).
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Opt-in alternative to RGB-direct's padded-copy staging at unaligned modes:
direct-import the visible-size capture and declare the TRUE-SIZE source
codedExtent. RADV has derived the VCN session_init firmware padding from
srcPictureResource.codedExtent since Mesa 24.2, so the EFC is told the source
lacks the alignment rows and the hardware edge-extends them internally --
which also reframes the 2026-07-20 field GPU reset: that crash passed the
ALIGNED extent as the source codedExtent (firmware padding zero) over a
visible-size buffer. Off by default until a guarded live test proves the EFC
front-end honors the padding like the YUV fetch path does; the padded-copy
staging remains the shipped behavior.

Drop the padded-copy staging for producer-native NV12 and direct-import the
visible-size buffer at unaligned modes (1080p) too. Safe by the driver's own
contract rather than by allocation luck: native sessions now author the H265
SPS / AV1 sequence header at the RENDER size and pass the matching codedExtent
on every picture resource. RADV rounds the bitstream SPS up itself (with a
conformance window -- radv_video_patch_encode_session_parameters, per the
VK_KHR_video_encode_h265 proposal's "implementations may override" clause) and
programs the VCN session_init with the true extent plus nonzero firmware
padding, so the hardware edge-extends the alignment rows internally and never
fetches past the source's real extent -- the exact mechanism VAAPI/radeonsi has
always used to encode 1080p. The driver-emitted header NALs already carry the
patched SPS, so the wire format is unchanged.
The CSC and RGB-direct paths keep the app-aligned convention (their sources
genuinely cover the aligned extent); RGB padded-copy staging is untouched.

Software decode uploads swscale RGBA with no CSC/tonemap pass. On the new
desktop-compositor HDR10 surfaces (GNOME 48 / Plasma 6 + Mesa >= 25.1 offer
ST2084 even on SDR desktops) that sRGB-encoded content was composed as PQ —
the field-reported psychedelic picture (Fedora clients decode HEVC in
software because stock Mesa strips it; reproduced + fix live-validated on
GNOME Wayland: mode-0 soup -> HDR→SDR washed-out-but-correct).
The CPU lane keeps the SDR swapchain and its known untonemapped-PQ gap; a
real PQ→sRGB pass for CPU frames is the follow-up.

GNOME 48 / Plasma 6 with Mesa >= 25.1 now offer HDR10_ST2084 surfaces even on

The native QSV encoder only attached mfxExtVideoSignalInfo on HDR sessions —
an SDR stream carried no colour description at all (NVENC writes 709-limited
unconditionally; qsv.rs now mirrors it).
Diagnostics for the field-reported blue/magenta Intel-host colours:
- hdr-p010-selftest takes an optional WxH + GPU vendor (intel|nvidia|amd) and
prints which adapter it tested — 64x64 on the default GPU proved nothing on
dual-GPU boxes, and the field heights (1080/1400) are not 16-aligned.
- pf-capture: ignored live test running the converter at 1920x1080 pinned to
the Intel adapter.
- pf-encode: qsv_live_p010_1080_colorbars_dump — known P010 bars through the
UNALIGNED-height ingest copy (1080 src -> align16 1088 pool, the seam no
640x480 test exercises) to Main10 HEVC, dumped for off-box decode checks.
- dxgi.rs: drop the stale 'falls back to the R10 path' claim (no such path).

With PUNKTFUNK_PIPEWIRE_NV12=1 (bring-up gate), the PipeWire negotiation
offers an NV12 LINEAR DMA-BUF pod (BT.709 limited pinned MANDATORY) ahead
of the BGRx one, and gamescope's producer-side RGB->YUV pass replaces the
host CSC entirely: the encoder imports the two-plane buffer as a profiled
VIDEO_ENCODE_SRC image and the VCN encodes it directly. Contributed
measurements: encode p99 2.9 ms (from ~4-4.5 ms via EFC RGB-direct),
60 fps capture, 0 send drops.
Hardening on top of the contributed patch:
- unaligned modes (1080p!) stage through a padded aligned NV12 copy (edge
rows/columns duplicated, transfer-only) instead of direct-importing the
visible-size buffer -- a direct import would make the VCN read past the
producer allocation, the exact OOB class behind the 2026-07-20 field GPU
reset; the encode extents return to the aligned coded extent everywhere
- the UV plane layout honors the producer's plane-1 chunk (offset/stride)
when the SPA buffer carries one (same-BO verified by inode), with the
contiguous-plane contract as fallback
- PyroWave sessions are excluded from the gate (their Vulkan compute CSC
ingests packed RGB), and a native-NV12 session that resolves to libav
VAAPI (H264 codec, PUNKTFUNK_VULKAN_ENCODE=0, feature off, or a failed
Vulkan open) refuses at open instead of streaming garbage chroma
- pad staging images carry TRANSFER_SRC (the width-padding pass self-copies
the staging image -- previously missing on 1366-wide modes)
- metadata-cursor one-shot warn (parity with RGB-direct) and a padded-NV12
PUNKTFUNK_PERF split label; the padded RGB copy gets its timestamps too

settle_desktop_portal pushes the live desktop's WAYLAND_DISPLAY into the
systemd --user manager (import-environment) so a re-activated portal inherits
the right session — but the import PERSISTS after that desktop dies. Every
later user unit then inherits the stale socket, including
gamescope-session.target: gamescope sees WAYLAND_DISPLAY, runs NESTED, and
aborts with "Failed to connect to wayland socket: wayland-0" — observed live
on a Deck, where Game Mode could not start at all (autologin crash-looped)
until the var was unset by hand.
Two-layer fix, mirroring the protection launch_session already gives its
transient unit:
- observe_session_instance: when a desktop compositor instance goes away,
unset WAYLAND_DISPLAY/DISPLAY from the manager env (a desktop bounce is
harmless — the next portal settle re-imports).
- write_steamos_dropin: UnsetEnvironment=DISPLAY WAYLAND_DISPLAY on the
takeover drop-in, unit-scoped belt-and-suspenders for host-initiated
restarts.

Observed live on a Deck host: the user switched Game Mode → Desktop, KDE came
up in 0.8 s — and the capture-loss rebuild's FIRST detection ran inside that
gap, still said Gaming, and its gamescope re-acquire restarted
gamescope-session.target. On SteamOS that steals the seat: the user was
yanked out of the KDE session they had just chosen, the two session managers
fought (job canceled / dependency failed), no gamescope node appeared within
30 s, and the stream died at the 40 s rebuild budget.
A rebuild probe acting on possibly-stale detection must never stop, relaunch,
or take over box sessions. New pf_vdisplay::rebuild_probe_scope (RAII,
counted): while held, the gamescope managed/takeover create paths only attach
to a live node and fail fast otherwise — no stop_autologin_sessions, no
session-plus relaunch, no gamescope-session.target restart. The capture-loss
loop holds it for the first 4 s after a loss (the detection-ambiguity
window); after that, destructive rebuilds are allowed again, so a genuine
switch INTO Game Mode still gets its headless takeover. Probe failures are
instant, so the loop now paces itself at ~2 Hz instead of spinning.

Two session-transition stalls found live on a SteamOS Deck host, one cause:
the pipeline retry loop couldn't tell a wait-it-out failure from a
retry-now-and-it-works one.
- Gamescope first-frame race: a PipeWire stream connected while gamescope
re-initializes its headless takeover negotiates a format, reaches
Streaming, and never receives a buffer — while a fresh connect delivers
within ~0.5 s. Every gamescope bring-up ate the full 10 s first-frame
budget on attempt 1 (17 s bring-ups; KWin: 1.2 s). The retry loop's FIRST
attempt now waits 2.5 s (Capturer::next_frame_within), so the reconnect
that fixes the race happens at ~3 s. Later attempts keep the patient 10 s
— the documented 30-60 s Big Picture cold start still fits the budget.
- Capture-loss rebuild vs session switch: the rebuild loop re-detects the
active session between build_pipeline_with_retry calls, but each call
burned 8 attempts (~13 s) against a compositor that no longer exists (a
Desktop→Gaming switch spent 13 of its 27 s retrying gone-KWin). The
capture-loss path now passes max_attempts=2, turning the outer loop into
~1 s detect-and-retry cycles that follow the box to the new session.
The resize path's direct build_pipeline call keeps the default budget (no
retry wrapper there to absorb an early bail).

The SteamOS scripts built the host featureless, so PlatformAuto could never
pick the Vulkan Video backend (default-on since 84329205) and every session
silently ran libav VAAPI — unlike the deb/arch/rpm/sysext builds, which all
pass the feature. Three gaps, found live on a Deck host:
- install.sh/update.sh: cargo build with --features punktfunk-host/vulkan-encode
(matches the packaged builds; pure-Rust ash, no new system dep).
- host.env: RADV_PERFTEST=video_encode — Van Gogh RADV still gates
VK_KHR_video_encode_* behind it, so without it the backend can't open and
falls back to VAAPI. Harmless where encode is exposed by default.
- io.unom.Punktfunk.Host.desktop (Exec rewritten to this install's binary):
KWin only grants zkde_screencast_unstable_v1/org_kde_kwin_fake_input to an
exe a .desktop authorizes — without it Desktop-Mode capture fails outright
and a mid-stream Game↔Desktop switch strands the stream on the old backend.
update.sh retrofits the last two idempotently so existing installs get them
without a reinstall.
Validated on a SteamOS 3.8.14 Deck (Van Gogh): Vulkan HEVC opened on both the
KWin and gamescope paths at 5120x1440 — in-place ABR reconfigure (no IDR, no
encoder rebuild) vs the VAAPI path's full teardown per ABR step, and Desktop
capture came up without a re-login.

`<CardContent className="p-0">` never removed the padding it looked like it
removed: tailwind-merge resolves conflicts within a variant, so `p-0` cancels
`p-4` but leaves `sm:p-6` standing. Every call site that used it nests a
CardHeader inside, which brings its own `sm:p-6` — so at >=640px the title sat
24px further in than its neighbours'. Visible on the Plugins page as 'Installed
plugins' not lining up with 'Plugin runner'.
Give CardContent a `flush` prop that omits the padding outright, and use it at
the three call sites (Store, Pairing, Stats) rather than fixing the symptom
three times and leaving the footgun in place.

The guard checked the package NAME shape, and `@punktfunk/plugin-kit` — the
framework every kit-built plugin depends on — matches `@scope/plugin-*`
exactly. Windows on-glass accepted an uninstall of it; bun no-ops removing a
non-dependency so nothing broke, but the store was offering to pull a library
out from under the plugins using it.
Require membership in the top-level dependency list, the same authority that
already keeps plugin-kit out of the installed listing. Same blind spot, two

Two things looked wrong in the store:
The cards had no space above the icon. `CardContent` zeroes its own top padding
(`pt-0`/`sm:pt-0`) because it normally sits under a `CardHeader` that supplies
it — but these cards have no header, so the top padding simply vanished while
the other three sides kept `p-card`. `p-card` does not undo it: `card` is a
custom `--spacing-*` token, which tailwind-merge does not recognise as a
spacing value and so never dedupes against `pt-0`, leaving the longhand to win.
Both header-less cards in this section now restore it explicitly, at both
breakpoints.
Platform chips read "windows" / "linux". Those are the catalog's platform
IDENTIFIERS (the index validator pins `linux | windows | macos`), which is right
for the wire and wrong on screen; the card now maps them to display names —
Linux, Windows, macOS. Proper nouns, so deliberately not routed through i18n.
Adds Store/StoreCard stories covering the padding, the platform labels, and the
installed / update / incompatible / blocked / external states, so the card can
be eyeballed without a host or a catalog.
Gates recorded (nvenc-subframe-slice-output.md Phase 3): loss-harness curve
identical streamed-vs-whole; adversarial security review clean; live .21
3-leg A/B — streamed 0 corrupted frames, p99 8527→5363 µs vs sliced-whole,
first_slice_us ~500 µs of a ~1250 µs encode reaching the send thread; wire
bytes rate-governed under CBR + 1-frame VBV (the ~1-2 % slice-header cost is
absorbed by rate control, not added to the wire). GameStream: plane has zero
code diff (own RTP packetizer; shares only untouched send_pacing); a live
Moonlight re-test joins the standing owed Moonlight item.
- resolve_slices(codec, default): env 1..=32 wins (1 = the NEW explicit
single-slice escape), else the backend default — 4 on Linux direct-NVENC,
1 elsewhere. resolve_subframe(default_on): PUNKTFUNK_NVENC_SUBFRAME
tri-state (0 = never, 1 = force, unset = backend default).
- Linux nvenc_cuda: resolves both ONCE in query_caps — the sub-frame default
is gated on the GPU's SUBFRAME_READBACK cap so an unsupporting GPU never
has enableSubFrameWrite forced into its init params — and feeds the same
resolved values to build_config, build_init_params (open AND in-place
reconfigure) and the chunked-poll latch.
- Windows: env-only as before (async path untouched, byte-identical config
for unset env); LowLatencyConfig.slices + the explicit subframe param
replace the shared env reads.
- Tests: chunked e2e now runs at the DEFAULTS (no knobs); the fallback test
becomes the escape test (SLICES=1 disarms; SUBFRAME=0 disarms while
4-slice encode continues on the plain poll path).

The bootstrap key generated during implementation was lost, and its
replacement was pasted into the wrong repository's secret store — Gitea
secrets neither cross repos nor read back, so neither is usable. The private
half of this one lives in punktfunk-plugin-index's own INDEX_SIGNING_KEY,
which is the only thing that signs the catalog.
Nothing has shipped pinning any of these, so this is a straight replacement
of slot 0; the second slot stays reserved for a genuine rotation.

B2 default-on (design/vulkan-rgb-direct-encode.md): wherever the probe
passes, Vulkan Video sessions now take the EFC RGB source by default —
direct import on aligned modes, padded-copy staging on unaligned ones
(1080p). PUNKTFUNK_VULKAN_RGB_DIRECT becomes the override: =0 disables,
=1 forces, unset = the default below.
The one session class that must NOT default on: cursor-as-metadata
captures (every non-gamescope compositor), where the CSC shader's blend
IS the visible pointer — the EFC cannot composite, and defaulting there
would silently drop the cursor from the stream. The hint rides the
existing plumbing:
- SessionPlan gains cursor_blend, resolved once where the compositor is
known (gamescope embeds the pointer itself → false; kwin/mutter/
wlroots/hyprland → true), and shows up in the logged plan line.
- open_video/open_video_backend thread it through (native pump: all
three encoder-open sites read plan.cursor_blend; GameStream monitor
capture: true — it negotiates metadata cursor; spike: false).
- VulkanVideoEncoder::open resolves: env override, else ON iff the
session never hands us cursor bitmaps. The warn-once for a cursor on
an RGB session (forced via =1) stays.
Verified on-hw box (Linux): pf-encode + punktfunk-host compile, clippy
clean, unit suite green. The GPU paths themselves are unchanged from the
smoke-validated 96e19986 — this commit only changes which sessions
select them by default.

Review verdict: no exploitable memory-safety / amplification / splice /
resurrection issue; nonce order and two-lane seal byte-identical for the
legacy path. Actionable findings applied:
- explicit per-block data_shards cross-check next to the recovery_shards
one (defense-in-depth — the geometry invariants make it unreachable
today, but have_data indexing assumes it)
- partial delivery skips an UNPINNED streamed frame (frame_bytes still 0)
instead of truncating its max-sized buffer to an empty "partial"
- regression tests for the two untested load-bearing guards: the
final-first out-of-range-sentinel drop (the exact-sized-buffer guard)
and second-final-with-different-totals rejection
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
The Phase-2 gate: more, smaller wire units must not regress FEC recovery.
Adds a GF16 streamed column (three chunk pushes + finish per AU — sentinel
blocks then real totals). Measured: identical to whole-AU at every loss
rate (50/50 through 1/6, the same 25%-budget cliff).

The probe's reassembler is the shared core one, and the probe is the tool
that measures the streamed-AU overlap win — advertise the cap so a host
with chunked encode streams to it.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
The wire half of sub-frame slice output (latency §7 LN1, planning
design/nvenc-subframe-slice-output.md Phase 2): toward a client that
advertises the new cap bit (0x20), a chunked-poll encoder session ships each
AU's completed FEC blocks while the tail of the frame is still encoding —
the AU's last packet leaves the host as the encode finishes instead of
after it.
Wire semantics (negotiated; zero change for anyone else):
- Non-final blocks ride SENTINEL headers: block_count = 0 (a value no legacy
sender emits) + frame_bytes = 0 + exactly max_data_per_block data shards,
so the receiver's shard-offset formula needs no total.
- The final block's headers carry the real frame_bytes/block_count (+
FLAG_EOF) and RETRO-VALIDATE the whole frame: totals under which a
received sentinel block is out of range or not full-K kill the frame
wholesale (no spliced delivery) and the index can't be resurrected.
- Firewall: sentinels are bounded by the negotiated limits (full-K exactly,
never the last block the limits allow, no total to lie about); the exact
derived-geometry check runs unchanged on every non-sentinel packet and
retroactively at pinning. Sentinel opens commit a max_frame_bytes buffer,
bounded by the existing IN_FLIGHT_BUF_FACTOR budget (amplification test).
- Order-agnostic like legacy: a reversed frame (final block first) opens
legacy-shaped and still accepts its sentinels against the pinned totals.
- Small/empty streamed AUs degenerate to byte-identical legacy headers.
Host: Packetizer::{begin,push,finish}_streamed seal full-K blocks (data +
parity per block) as chunks arrive; Session::seal_streamed_* share the
pooled-wire + two-lane seal machinery via the new seal_run; the send thread
paces each flush under the frame's existing deadline (pace_sealed split out
of paced_submit) and runs the whole-AU accounting at the last chunk; the
encode pump forwards poll_chunk output as ChunkMsg when the client has the
cap AND the encoder chunks (re-queried per AU — an escalation falls back
seamlessly). Probes never run mid-AU. PUNKTFUNK_STREAMED_AU=0 = host escape
hatch. Client core ORs the cap into Hello (the shared reassembler carries
the support). Sampled first_slice_us vs encode_us PERF log measures the
overlap; the 0xCF stage-field extension stays a follow-up.
Core tests: streamed round-trip (clean/loss/reorder/duplicate, both orders),
sentinel firewall bounds, lying-final wholesale kill + no-resurrect,
open-amplification budget, header-shape pins. Gates still owed before
default-on: security review pass, loss-harness curve, GameStream smoke
(plane untouched structurally), bitrate A/B.

The encoder half of sub-frame slice output (latency §7 LN1, planning
design/nvenc-subframe-slice-output.md Phase 1): with PUNKTFUNK_NVENC_SLICES=N +
PUNKTFUNK_NVENC_SUBFRAME=1 on a sync depth-1 session, Encoder::poll_chunk hands
the in-flight AU out as slice-boundary chunks read through doNotWait sub-frame
locks while the tail is still encoding — the readback loop the on-hw probe
validated (~200 µs slice spacing on the 5070 Ti), productionized.
- codec.rs: AuChunk (AU metadata on the first chunk, `last` closes the AU;
chunks concatenate to exactly the poll() bytes) + supports_chunked_poll /
poll_chunk trait surface. Default impl wraps poll() as one self-closing
chunk, so a chunk-driven consumer works against every backend.
- nvenc_cuda: chunked readback cut at slice boundaries only (bitstream size at
n reported slices = end of slice n, Annex-B contiguous); completion is NEVER
numSlices alone — one finishing BLOCKING lock is the authority and the wedge
watchdog, so the final chunk blocks exactly like sync poll (the depth-1 pump
contract; 6dc195f9 bug class). Keyframe on early chunks is the submit-time
IDR prediction (exact under P-only/infinite-GOP), cross-checked at finish.
Debug builds shadow-check emitted chunks against the finished AU prefix.
Mutually exclusive with pipelined retrieve (gated off when async_rt exists,
dropped by the escalation rebuild); composes with stream-ordered submit.
- nvenc_core: slices_env/subframe_requested shared parses so the config author
and the chunked-poll arming can't disagree.
- TrackedEncoder forwards both new methods (the set_wire_chunking trap class).
Host loop untouched — Phase 2 (VIDEO_CAP_STREAMED_AU seal/send) consumes this.
On-hw: nvenc_cuda_chunked_poll_end_to_end + nvenc_cuda_chunked_poll_fallback_whole_au.

Every session encoder is boxed in TrackedEncoder (open_video), and the
wrapper never forwarded Encoder::set_pipelined — so the host loop's
contention escalation (ae673158) hit the trait default, which returns
false ("backend can't pipeline, stop asking"), and the pipelined-retrieve
stage could never engage adaptively. Only the explicit
PUNKTFUNK_NVENC_ASYNC=1 open-time path worked. The exact defaulted-method
trap the wrapper's own comment documents for set_wire_chunking.

Console: a Plugins section (Browse / Installed / Sources) on a static nav
entry, with install friction proportional to trust — a plain confirm for a
verified entry, a warning naming the curator for an external one, and a
danger dialog that makes you retype the spec for a raw package. Tier badges
are permanent and follow the plugin onto its own UI page.
Index: unom/punktfunk-plugin-index published and served from Gitea's raw
endpoint (real HTTPS, byte-exact, no vhost to stand up) — merge to main is
publish, which resolves the design's open hosting question.
Four things only running it could find:
- runner discovery matched @punktfunk/plugin-* only, so a third-party
scoped plugin (which D8 requires) would install and never run
- ...and that convention also matches @punktfunk/plugin-kit, a plugin's
own framework: it listed as installed and would have been imported as a
unit. Both now key off the plugins dir's top-level dependencies, with an
emptied dependency list meaning 'nothing installed' rather than falling
back to the naming convention
- the store must not pass new flags to the runner: the scripting package
ships separately and an older one reads an unknown flag's value as a
package name. The host writes the bunfig scope mapping itself
- ureq reports only >= 400 as Err, so a conditional request's 304 arrives
as Ok with an empty body — handled as an error it made every refresh
after the first verify a signature over zero bytes and sit stale
Also: the console's first Tabs use exposed an @unom/ui theme gap that
rendered inactive tabs invisible (caught in a browser pass, not by types).

The index is the verification gate: a catalog entry pins one exact version
plus that version's tarball integrity hash, so 'verified on every release'
is a property of the data rather than a promise about process. Nothing can
express 'track latest' for a catalogued plugin.
- store/index.rs signed index parse + ed25519 verify (ring), validate-and-drop
per entry, semver minHost/advisory ranges
- store/sources.rs built-in unom source (compiled-in URL + two key slots for
rotation) + operator sources in plugin-sources.json
- store/catalog.rs https fetch with size/timeout/redirect caps, signature before
parse, last-good disk cache (stale-but-usable when offline)
- store/jobs.rs single-flight install/uninstall: registry-integrity preflight
against the pin, spawn the runner CLI with live log capture,
post-install version check with rollback, provenance record,
runner restart (discovery is startup-only)
- store/manifest.rs install provenance; absence means CLI-installed
- mgmt/store.rs 12 routes under /api/v1/store, denied to the plugin token
(a plugin that can install plugins is an escalation primitive)
Also generalizes runner discovery and listInstalled from @punktfunk/plugin-*
to ANY scope's plugin-*: catalog entries must be scoped so the scope can map
to that entry's registry, so a third-party plugin necessarily arrives under
its own scope and would otherwise install but never run.

Lifts 3aacec53's alignment gate into a mode select: an aligned mode keeps
the true zero-copy direct import; an unaligned one (1080p!) now blits the
visible frame into a per-slot ALIGNED BGRA staging image and duplicates
the edge rows/columns into the 64x16 padding — transfer-only regions in
one vkCmdCopyImage (1080p: visible + 8 row regions; width padding adds a
second self-copy pass in GENERAL), no compute shader. The encode reads
the staging image, never the capture buffer, so the EFC can never read
past a producer allocation (the field GPU hang). Still one ~8 MB copy vs
the CSC path's ~17 MB + dispatch + plane copies. Verdict line:
active(padded-copy). The staging import drops the video profile entirely
(TRANSFER_SRC only).
CPU-payload paths made honest on the way (they were the smoke baseline
AND the software-capture fallback):
- rgb mode: the staging upload is padded CPU-side (edge duplication) so
the aligned encode-src is fully defined;
- CSC mode: the sampled image is now SOURCE-sized with a matching copy
extent — the old aligned-size image + tightly-packed buffer sheared
rows and left garbage rows at unaligned modes (black-bar artifacts;
YMIN=16 in every smoke frame), which also masked as a 24 dB PSNR
'regression' against the (correct) padded output.
On-glass (780M, host Mesa 26.0.4): all four smokes pass at 256x256
(direct) AND 250x250 (padded); padded-EFC frames decode perfectly
uniform (YMIN==YMAX) at the exact 709-narrow values (79/148/60 for the
first three fills); CSC-vs-padded PSNR 49.9 dB avg after the baseline
fix. clippy clean.

Field report (commit 25624443, RDNA2/VCN3 host, 1080p): repeated VCN0 VM
protection faults from punktfunk-host, vcn_enc_0.0 ring timeouts, two ring
resets, then a failed reset escalating to a full MODE1 GPU reset with VRAM
loss. Root cause is B1's RGB-direct source: the session's coded extent is
64x16-aligned (1920x1088) but the captured dmabuf is only the real mode
size (1920x1080) — the VCN EFC reads the 8 padding rows past the end of
the buffer (8 x 7680 B = 61 KB, matching the faulting page span exactly).
The CSC shader absorbs alignment by clamping reads and duplicating edges;
RGB-direct has no such stage. Every prior validation surface happened to
be aligned (256x256 smoke, 1440p live box) — 1080p is the common mode
that is not. The stall watchdog's rebuild-and-refault loop then turned a
per-session fault into the GPU death spiral.
Two layers:
- Open-time gate: RGB-direct engages only when the real mode equals the
aligned coded extent (720p/1440p/4K yes, 1080p no); otherwise the CSC
path runs and the verdict line says why (unaligned-mode). The padded-
copy variant that re-enables 1080p is design-doc B2 work.
- Submit-time check: an RGB-direct frame that does not cover the coded
extent errors out (encoder-rebuild path) instead of importing an
undersized source.
On-glass (780M, host Mesa 26.0.4): all four smokes pass aligned; at
PF_SMOKE_W/H=250 the gate refuses RGB-direct and the rgb smokes soft-skip.
clippy clean.

CardContent is shadcn's header-adjacent variant (`p-4 pt-0 sm:p-6 sm:pt-0`),
but the four Live-status tiles use it with no CardHeader. tailwind-merge lets
the call site's unprefixed `p-4` cancel the base `pt-0`, yet nothing cancels
`sm:pt-0` — so the tiles lost their top padding at >=640px only, and the
content sat against the top edge. Restores the top inset at the sm breakpoint
and lets the content fill the stretched grid cell so it stays centred when a
sibling tile is taller.

The RGB→NV12 compute CSC shares the SMs with the game; request an
elevated global-priority queue (VK_KHR/EXT_global_priority) so the
driver can schedule it ahead. PUNKTFUNK_VK_QUEUE_PRIORITY =
off|high|realtime (default realtime), downgrading REALTIME→HIGH→none
on NOT_PERMITTED/INITIALIZATION_FAILED — a refused class never fails
the bridge. Mirrors PyroWave's ac0e7332 (same honest caveat: WDDM
didn't move; the Linux driver may — contended-tail lever, correct and
harmless either way).

PUNKTFUNK_NVENC_ASYNC gains a real tri-state: 1 = always (as before, now
documented as ~+1 tick at depth-1), 0 = never (vetoes escalation), unset =
ADAPTIVE — off until the session loop's cadence-overrun detector escalates.
The host loop's adaptive-depth leaky bucket grows a second stage: once the
capturer's depth is maxed (Linux portal is permanently depth-1), it asks
the encoder for pipelined retrieve via the new Encoder::set_pipelined hook
(asked exactly once; default impl declines, Windows untouched).
nvenc_cuda engages at a safe point via a clean session rebuild WITHOUT the
IO-stream binding: with input==output stream bound, later stream work
waits on prior encode completions and would serialize a pipelined session
— stream-ordered submit and two-thread retrieve are mutually exclusive.
The ordered gate now also requires async_rt absence (belt-and-braces for
the runtime switch). Re-open's first frame is the standard session IDR.
On-hardware test: escalate mid-session → retrieve thread live, binding
gone, all AUs deliver, first post-escalation AU is the IDR.

design/vulkan-rgb-direct-encode.md B1: when the probe passes AND
PUNKTFUNK_VULKAN_RGB_DIRECT=1 (default OFF until the B2 on-glass A/B),
the session opens with pictureFormat=B8G8R8A8 and the captured RGB frame
becomes the encode source — the VCN EFC front-end does the 709-narrow CSC
inline during encode. Deleted from the per-frame path: the compute CSC
dispatch, both NV12 plane copies, the semaphore hop and one queue submit
(dmabuf frames are ONE encode-queue submit; ~17 MB/frame of GPU traffic
gone). The DPB stays NV12; RFI/RC/quality-level machinery is untouched.
Shape:
- probe_rgb_direct now returns the chroma-siting bits to create the
session with (midpoint preferred, else cosited-even per axis); the open
verdict line gains "active" / "available(off; ...)" states.
- RgbProfileStack: the rgb-chained video profile rebuilt on the stack per
profiled-image creation after open (profile identity is by value) —
dmabuf imports become profiled VIDEO_ENCODE_SRC images (import cache
unchanged), the CPU staging image likewise (concurrent encode+compute).
- record_submit_rgb: steps 2–4 twin (dmabuf: single submit; CPU: staging
copy on the compute queue, semaphore-ordered); shared step-1/bookkeeping.
- begin_encode_cmd takes a SrcAcquire (CSC general / fresh-import FOREIGN
QFOT / cached visibility-only / staging TRANSFER_DST) so both paths
share the encode recording.
- RGB-direct frames skip the CSC per-slot resources entirely (make_frame
split into csc/common halves); cursor bitmaps warn once (EFC cannot
composite; gamescope — the flagship — embeds the cursor itself).
On-glass (780M RADV PHOENIX, host Mesa 26.0.4): all four smokes pass
(vulkan_smoke{,_av1,_rgb,_rgb_av1}); the EFC-encoded H265 stream decodes
clean and matches the CSC-encoded stream at 49.9 dB average PSNR (min
48.9) — within the design's ±1-code-value tolerance. (Raw-OBU ffmpeg
probing of the tiny AV1 dumps fails identically for BOTH paths —
pre-existing dump quirk, not a stream defect.) check+clippy+full unit
suite green.

servePluginUi's Bun.serve leaves idleTimeout at Bun's 10s default, so the old
15s keepalive could never arrive — an idle status feed was closed before its
first ping, which is exactly what a live host showed. Default is now 5s.
Also adds the regression suite that should have caught it: the original test
only covered a finite, self-driving stream. The new one exercises the
production shape (PubSub-backed, published after the response opens) plus the
keepalive — with a reader that does not re-enter read(), which is what made the
first version of this test lie.

PUNKTFUNK_NVENC_SLICES=N (2..=32, default off) splits H.264/HEVC frames
into N slices (sliceMode 3); PUNKTFUNK_NVENC_SUBFRAME=1 (default off)
arms enableSubFrameWrite + reportSliceOffsets on sync sessions only.
Both experimental groundwork for sub-frame slice output (plan §7 LN1).
nvenc_cuda_subframe_slice_probe (on-hardware, ignored) answers the LN1
go/no-go: spins lock_bitstream(doNotWait) against an in-flight frame and
prints the (t_us, status, numSlices, bytes) timeline — incremental slice
availability and its spacing, or all-at-completion.

On-glass B0 result from the 780M (RADV PHOENIX, host Mesa 26.0.4): the
probe returned no-709-narrow-midpoint because RADV advertises
xChromaOffsets = COSITED_EVEN only — the VCN EFC does canonical H.26x
left-cosited x-chroma, while the requirement was written to bit-match our
2x2-average (midpoint) shader. The delta is a half-pel chroma-x phase,
imperceptible and unsignalled in our bitstream; EFC's siting is arguably
the more correct one. Accept either siting bit per axis (model + range
stay exact: 709 narrow); B1 will pass the preferred available bit.
With this the 780M probes rgb_direct=available; both GPU smoke tests
(H265 + AV1) pass on that box against host Mesa 26.0.4 — the first
real-RADV validation of the poll fix, the quality-level control, and B0.
(Container mesa alone can't run the H265 smoke: Fedora ships RADV with
H264/H265 encode compiled out — AV1 only. Use the host ICD via
VK_ICD_FILENAMES on Atomic boxes.)

@unom/ui reads --secondary as muted TEXT; this palette (like the console's) uses
it as a dark SURFACE, so EmptyState captions, badge text and table headers

instead of in each plugin's stylesheet.

Bind the session's IO streams to the encode thread's high-priority copy
stream: in sync-retrieve depth-1 use the per-frame input copy and cursor
blend now enqueue with NO cuStreamSynchronize and encode_picture orders
after them on the stream. Same stream both directions, so the encode's
completion is inserted into the stream and later work (the next frame's
copy into a reused ring slot) waits for it.
Soundness gate: the fast path engages only when pending is empty (true
depth-1 usage) — every prior encode was drained by a blocking poll, and
the caller holds the frame payload across the matching poll (contract now
documented on Encoder::submit; both host loops already comply). Pipelined
callers and PUNKTFUNK_NVENC_ASYNC mode keep the blocking copies.
True zero-copy input registration (registering the worker-owned IPC
buffer directly) stays the LN2 v2 follow-up — it needs a contiguous
worker-pool NV12 layout and a registration<->IPC-mapping lifetime tie.
PUNKTFUNK_NVENC_STREAM_ORDERED=0 restores the old blocking behavior.

Latency plan §7 LN0 (Linux/NVIDIA encode follow-on):
- sampled PUNKTFUNK_PERF submit split (copy/blend/map/pic) in nvenc_cuda —
the host loop's submit_us folds all four together; the D2D input copy is
the LN2 zero-copy target and now measurable on its own
- sampled blocking lock_bitstream timing on pf-nvenc-out — in two-thread
mode the host loop's wait_us wraps a non-blocking poll, so the real
encode wait was measured by no timer
- caps probe + log SUPPORT_SUBFRAME_READBACK / SUPPORT_DYNAMIC_SLICE_MODE
(LN1 sub-frame slice-output prerequisites, fleet visibility)
- explicit zeroReorderDelay=1 in the shared low-latency config (P-only +
no lookahead has no reordering anyway; pins the bit against preset or
driver drift; shared with the Windows backend)

First phase of design/vulkan-rgb-direct-encode.md (punktfunk-planning): make
the captured BGRx dmabuf the direct encode source with the VCN EFC front-end
doing the 709-narrow CSC — deleting the per-frame compute CSC, both plane
copies, the semaphore hop and one queue submit.
B0 changes nothing about the encode path. It vendors the extension surface
(vk_valve_rgb.rs — ash 0.38 predates it; same rationale and style as the
vk_av1_encode module) and probes at open whether this host qualifies:
extension present (Mesa >= 26.0 + EFC hardware) → feature bit → conversion
caps cover the compute shader's exact math (709 / narrow / midpoint both
axes) → encode-src format set offers B8G8R8A8 with DRM-modifier tiling.
The verdict is one INFO line (rgb_direct=available | first missing
requirement) — the field telemetry that decides where B1 can default on.
Verified: cargo check + clippy clean + unit tests green (Linux box); the
probe short-circuits to no-ext on non-RADV drivers.

Field follow-up to 6dc195f9 (the AMD host whose H265 encode sits at ~5 ms):
the remaining time is the VCN ASIC preset, and we never chose one.
1. Explicit encode quality level. RADV only emits a VCN preset op when the
app issues ENCODE_QUALITY_LEVEL — we never did, so every session ran the
firmware's default preset. Install the resolved level on the first
frame's RESET control (chained ahead of the CBR state, which satisfies
the spec's quality-change-carries-rate-control rule) and bake the same
level into the session-parameters object (the spec requires the match).
Default 0 = the fastest tier the driver exposes (RADV: SPEED, except
H265 on pre-RDNA4 which the driver pins to BALANCE); clamped to the
profile's maxQualityLevels. PUNKTFUNK_VULKAN_QUALITY=0..3 overrides for
quality-biased setups. Logged at open so field logs show the tier.
2. Persistent bitstream mapping. read_slot vkMapMemory/vkUnmapMemory'd the
host-visible bitstream buffer every frame; map each ring slot once at
build instead (coherent memory; vkFreeMemory implicitly unmaps).
3. PUNKTFUNK_PERF CSC split. GPU timestamps bracket the compute batch
(import barriers + cursor prep + CSC dispatch + plane copies) and a
sampled csc_us line logs every ~2 s — separating shader/copy time from
the ASIC encode inside the pump's wait_us, the VAAPI submit-split
analog for this backend. Off (and unrecorded) unless PUNKTFUNK_PERF.
Verified: cargo check + clippy + DPB/RPS unit tests green (Linux box).
The GPU smoke tests still need a RADV host (NVIDIA driver fails session
open on the build box, pre-existing).

The session pump's depth-1 loop (capture → submit → poll) treats a poll()
None as "the backend holds the frame internally, re-poll next tick" —
true only of the libav AMF/QSV wrappers, whose codecs genuinely hold ~2
frames. The Vulkan Video backend probed its slot fence with
get_fence_status instead, so the AU of every frame — finished on the
ASIC in ~5 ms — sat unharvested until the tick AFTER the next frame was
submitted: encode_us read as one full frame period (~17 ms at 60 Hz vs
VAAPI's ~5.3 ms on the same VCN, the AMD field report) and every frame
shipped a frame period late — one frame of avoidable glass-to-glass
latency on the path that exists to beat libav VAAPI.
Wait the oldest in-flight slot's fence in poll() instead, matching the
sync NVENC backend's blocking lock_bitstream and the documented
Capturer::pipeline_depth contract ("capture → submit → poll-blocks").
Bounded by ENCODE_FENCE_TIMEOUT_NS like enqueue()'s backpressure wait,
for the same reason: poll runs on the thread the stall recovery runs on,
so a wedged GPU must surface as an error, not park it. None now only
means "nothing submitted". Covers H265 and AV1 (shared poll).
Verified: cargo check + DPB/RPS unit tests green (home-worker-5); the
GPU smoke tests fail at session open on that box's NVIDIA driver
identically on unmodified origin/main — pre-existing, needs the RADV
box for on-glass.

`web/project.inlang/settings.json` pointed `modules` at
https://cdn.jsdelivr.net/npm/@inlang/plugin-message-format@4/dist/index.js —
inlang's stock `paraglide-js init` scaffolding, which nobody had a reason to
keep. It made `bun run codegen` need the network at build time, so in a
sandbox that has none (the Nix build; any air-gapped CI) the plugin import
failed and paraglide compiled ZERO messages.
That failure is silent by design: the inlang SDK logs a PluginImportError as a
WARNING, paraglide still prints "Successfully compiled" and exits 0, vite
bundles the empty message set, and the console only dies at request time inside
renderToReadableStream because every `m.foo()` is undefined. Reported from a
NixOS host running punktfunk-web-server.
The plugin is a normal npm package, so depend on it like one: add
@inlang/plugin-message-format as a devDependency and reference it by relative
path. `loadProjectFromDirectory` (which both `paraglide-js compile` and the
vite plugin use) imports non-`http` modules straight off disk, and the shipped
dist/index.js is a self-contained bundle with no imports of its own, so it
loads from the data: URL exactly as the CDN copy did. Compiles 268 messages
offline, with no project.inlang/cache round-trip.
Add tools/check-i18n.mjs, run at the end of `codegen`, so this can never ship
silently again: it fails the build on a remote `modules` entry, a module that
does not resolve, or a compiled message count below what messages/en.json
defines. Verified it catches all three (remote URL, missing plugin, corrupt
plugin that compiles to 0 messages) and passes a healthy build.

- ui-server + sse: effect/unstable/httpapi behind servePluginUi with
core-only env layers (validated by the phase-0 spikes); raw SSE route
(httpapi has no event-stream media type)
- cli: minimal command dispatcher reusing the plugin layer graph
(deliberately not effect/unstable/cli — it needs platform packages)
- react subpath: plugin router (path→hash→fallback deep-link restore +
pf-ui:navigate bridge), ResultGate, sseAtom, resolvePluginBase
- theme.css: the console's violet identity packaged for plugin UIs
18 bun tests incl. the two phase-0 spikes; publish workflow mirrors
sdk-publish (tag plugin-kit-v*; 0.1.0 published manually).

Manual publish (no sdk-v tag — the version was published directly so the
plugin-kit and rewritten rom-manager can consume pluginStateDir/pluginIngestDir
from the registry; the previously published 0.1.1 predates the security-tiers
merge and lacks those exports).

Two spikes validating the riskiest seams of the plugin-kit design before
implementation:
- HttpApi (effect/unstable/httpapi) served on Bun behind the SDK's
servePluginUi using ONLY effect-core layers (Etag.layerWeak, Path.layer,
HttpPlatform.layer + FileSystem.layerNoop) — no platform package. Auth,
schema validation, and static fallthrough all verified end-to-end.
- Browser client prefix strategy for the console proxy: both
transformClient+prependUrl AND baseUrl preserve the /plugin-ui/<id>
path prefix. Nested Schema.withDecodingDefaultKey defaults confirmed
(Effect-valued defaults; encodingStrategy "omit" restores raw shape
on encode).

Second and final batch from the 2026-07-20 core-sweep lows:
client:
- connect() timeout now sets `quit` before shutdown, so a handshake that
completes after the deadline closes with QUIT_CLOSE_CODE instead of
leaving the host lingering (virtual display up) for a reconnect that
never comes.
- probe_result: saturating_add on the wire-supplied wire_packets +
send_dropped counters (debug-build overflow panic / release wrap).
- the standing-latency bleed no longer sets flush_in_window: that flag
is the ABR's SEVERE (×0.7) verdict, and the bleed fires only on
provably loss-free windows the controller itself scores as fine.
clipboard:
- fetch_cancels pruned on every new fetch (was: one dead oneshot per
paste for the session).
- serve chunks gated on a parked waiter + capped at CLIP_FETCH_CAP with
an Error event (was: unbounded silent accumulation under any req_id).
- serve_inbound park bounded by FETCH_STALL_SECS + send.stopped() (was:
an unanswered FetchRequest parked the task, waiter, and bi-stream
forever; ~100 of them exhaust the connection's bidi budget).
C ABI (ABI_VERSION 9 → 10, header regenerated, additive only):
- new punktfunk_connection_clock_offset_now_ns — the LIVE re-synced
offset (Swift/Kotlin latency math read the frozen connect-time value
~40ms wrong after a wall-clock step).
- to_config: checked u64→usize narrowing of max_frame_bytes (32-bit
armeabi truncated >4GiB to a plausible residue).
- host_poll_input: no &mut held across the embedder callback (re-entry
aliased it — UB under noalias); mid-drain callback clears now stick.
- next_audio_pcm: DTX (empty) payloads skipped — decode synthesized
120ms of concealment per 5ms slot and grew the playout ring forever.
- next_clipboard releases the parked payload on an empty poll (a one-off
50MiB paste stayed resident all session).
- frames_dropped / wants_decode_latency write their documented 0/false
defaults before the NULL-handle check.
- gamepad constant docs match pick_gamepad() reality (DualSenseEdge/
SwitchPro landed; DualSense/DS4 honored on Windows UMDF too).
FEC:
- gf8 reconstruct/reconstruct_into reuse the (k,m) codec cache like
encode_into (was: fresh 230×200 generator + decode inversion per
lossy block on the pump thread).
- vendored fec-rs: the 8 safe wrap_mul_slice shims assert equal lengths
(x86 SIMD callees bound stores on input.len() — safe-code OOB write);
ReconstructShard's safety contract gains the len()==get().len()
clause and reconstruct_internal sizes raw slices from the slice.
transport/GTK:
- Linux GSO super-buffer capped at the real UDP payload ceiling (65487)
not 65535 — seg sizes ≥1024 could EMSGSIZE and latch GSO off
process-wide, blamed on the network.
- GTK settings dialog no longer rewrites an unlisted-but-valid stored
gamepad preference to "auto" on close.
Already fixed on main (verified stale, skipped): the reassembler FEC
ceiling, wants_decode_latency's third term, request_probe rollback +
the generalized probe watchdog.

From the 2026-07-20 punktfunk-core quality sweep's adjudicated lows
(~/punktfunk-sweeps/punktfunk-core-2026-07-20.json), each with a
regression test:
- session: the two-lane seal's dead-worker fallback dropped the frame's
back half and returned Ok with half an access unit; the corpse lane
was also never respawned. The send-failure arm now reclaims the tail
(single-lane seals the WHOLE frame) and both failure arms drop the
lane so the next large frame respawns it. A recv-side death now
surfaces as an error instead of silent truncation.
- reassemble: Reassembler::reset() left pending_partial parked, so a
pre-flush stale partial survived Session::flush_backlog and was
delivered as the first "frame" after a jump-to-live.
- caps: resolve_codec echoed a non-conformant multi-bit preferred byte
verbatim (downstream from_wire folds it to HEVC — possibly outside
the shared set). It now isolates one bit of the intersection.
- endpoint: stream_transport_idle only floored the value; an absurd
operator-supplied idle timeout blew past QUIC's VarInt ms ceiling and
panicked host startup through the expect. Clamped to 1s..1h.
- pairing: PairRequest::encode cut the device name at a raw byte-64
boundary, splitting multi-byte UTF-8 (host showed U+FFFD forever);
it now shares Hello's char-boundary truncate_to.
The frozen-FEC-ceiling finding (reassemble.rs:109) was already fixed on
main by the sweep's high-severity commit — skipped as stale.

- build.rs: drop the stale `rerun-if-changed=src/client.rs` (the file
became client/ in W7; the path never fires).
- lib.rs: the crate doc's module list named 6 of ~19 modules — add the
missing ones (config/error/stats/input/reject/reanchor/render_scale/
audio/wol + the quic-gated control-plane group), without intra-doc
links to feature-gated modules.
- quic/mod.rs: the module doc still described the deleted `msgs`
module; list the actual post-split module set.

client/pump.rs was a single 1192-line async fn stacking six concerns.
It is now a 190-line orchestrator (same spawn order, same channel
wiring) over five focused modules:
- pump/handshake.rs — connect + Hello/Welcome/Start + skew handshake +
hole punch + Session construction (HandshakeOut)
- pump/input_task.rs — the gamepad snapshot/removal/arrival re-send
state machine + passthrough input forwarding
- pump/control_task.rs— the control-stream select loop (renegotiation,
probes, bitrate acks, clock re-sync, clip
metadata), bundled as ControlTask
- pump/datagram_task.rs — the datagram tag demux + rumble reorder gate
- pump/data.rs — the blocking data-plane pump (loss reports, ABR
+ capacity probe, jump-to-live detectors,
standing-latency bleed), bundled as DataPump
Every body moved verbatim (dedent + arg-struct destructures aliasing
the original binding names); no per-frame indirection added — the pump
loop, its locals, and the hot-path shape are byte-equivalent. The
Ctrl/DataPump arg structs exist only to stay under too_many_arguments.
196 lib tests pass; clippy clean on --features quic AND
--no-default-features (--all-targets); include/punktfunk_core.h

session.rs (1203) sharpens down to the two hot-path state machines +
lifecycle (887): ReplayWindow + seq_of + their tests -> session/replay.rs;
the PUNKTFUNK_PERF trio PumpPerf/SealPerf/TimedCoder -> session/perf.rs;
the Phase-1.5 lane machinery SealLane/SealJob/seal_wire_slice/
TWO_LANE_MIN_PACKETS -> session/seal.rs. Facade pattern (session.rs stays
the parent file); pub use keeps session::{PumpPerf,SealPerf} stable and
lib.rs re-exports are untouched. Pure code motion + pub(super) bumps —
seal_frame_inner/poll_frame/poll_input bodies unchanged; the

quic/tests.rs (1813 lines, 43 tests) was the W7 split's leftover: the
source moved into handshake/caps/control/clock/pairing/pake/datagram/
endpoint/clipstream/io but every test stayed in one monolithic file.
Each test now lives in a #[cfg(test)] mod tests at the foot of the
module it exercises, verbatim. The two CompositorPref/GamepadPref
wire/name tests moved to config.rs (where those enums live), so they
now also run under --no-default-features. The clip_loopback and
ctrl_framing integration mods share connect_pair via a cfg(test)-only
quic/test_util.rs.

`ci.yml`'s clippy gate has been failing on main since the pre-0.16.0 sweep landed, and
because clippy stops at the first crate it can't compile, the visible error was only
ever the first of four. `ci.yml` is not tag-triggered, so v0.16.0 cut and shipped over
a red main; none of this reaches the release artifacts (the two E0308s are in a test
binary and a dev tool, and the rest are lints) but the gate has been blind since.
Fixed, in the order clippy surfaced them:
- clients/probe failed to COMPILE (E0308, x2). `810d918d` moved `clock_sync` onto the
resumable `io::MsgReader` but only updated the client pump, leaving the probe passing
a bare `&mut RecvStream`. The probe now wraps the control stream in a `MsgReader` at
`open_bi` and threads that everywhere — Welcome, the --remode and --bitrate watchers,
and the speed-test result read — which is also what the refactor was for: those reads
sit behind timeouts and `select!`, exactly where a straddling frame would desync the
stream for the rest of the run.
- pf-capture: `SPA_META_Cursor as u32` is a `u32 -> u32` no-op
(`clippy::unnecessary_cast`). Line 1274 already passes the same constant uncast, so
the type is not in question.
- pf-inject: `noop as usize` on the SIGUSR1 wake handler added in `986402f7` trips
`clippy::function_casts_as_integer`; goes via `*const ()` as the lint asks. Same value
in the `usize`-typed `sa_sigaction` slot.
- punktfunk-core: the `ctrl_framing` test module's `use super::*` is unused, which
`-D warnings` promotes to an error.
Verified with CI's own commands on a Linux box (this is all Linux-gated code, so a Mac
cannot check it): `cargo clippy --workspace --all-targets --locked -- -D warnings`
finishes clean, `cargo build --workspace --locked` succeeds, and
`cargo test --workspace --locked` exits 0 with no failures — including punktfunk-core's
196-test suite, which covers the control-stream framing the probe change touches.

The flathub remote-add has now burned its entire retry budget and failed the job on
three consecutive tag builds — v0.15.0, the v0.15.0 re-point, and v0.16.0 — each one
needing a manual re-run to land the bundle.
The cause was already root-caused here on 2026-07-11 (see the Tooling step's comment):
home-runner-1's Docker embedded resolver at 127.0.0.11 drops UDP lookups while the
shared multi-org fleet is saturated. Nothing retransmits a dropped datagram, so the
lookup simply times out. The fix then was to widen retry.sh to 10 attempts (~9 min),
which comfortably outlasts a main push's ~8-workflow fan-out — but a TAG push starts
13 workflows at once, and that burst now outlives the whole budget. Retrying harder
is chasing the symptom; the transport is the problem.
`options use-vc` moves resolution to TCP, where the kernel retransmits and a query
cannot be silently lost under load. Same resolver and search path — only the
transport changes — so internal names still resolve exactly as before. Deliberately
no additional nameservers: a public resolver in the list could answer an internal
name (git.unom.io) with NXDOMAIN. retry.sh stays as the backstop for real upstream
blips.
Applied non-fatally, because Docker bind-mounts /etc/resolv.conf and may present it
read-only: a DNS tuning that cannot be applied must not be the thing that fails a
release build. If the write is refused we warn and stay on UDP, i.e. exactly today's
behaviour.
Scoped to the flatpak workflow, where the failure is actually evidenced, rather than
applied fleet-wide on suspicion.

v0.16.0's Apple leg failed at the xcframework build with "No space left on
device (os error 28)": the runner's boot volume was at 100% with 152 MB free.
None of the four `xcodebuild archive` calls passed -derivedDataPath, so each one
used the default ~/Library/Developer/Xcode/DerivedData/<name>-<hash> — and that
hash is derived from the PROJECT'S ABSOLUTE PATH. act_runner rotates its
workspace (~/.cache/act/<hash>/hostexecutor), so every rotation looked like a new
project to Xcode and minted a fresh ~760 MB tree. Nothing ever collects those:
they live outside the workspace, so act's own cleanup never sees them. 31 had
accumulated in three days (17 -> 20 July), which with the 12 GB shared
ModuleCache came to 32 GB — on a 228 GB volume already 95% full.
Pin all four archives to one path. The tree is now REUSED rather than multiplied,
which also keeps the module cache warm instead of rebuilding it per run. The new
step additionally prunes anything week-stale left in the default root, covering
both the legacy per-path trees and any other job that lands there.
Cleared by hand on home-mac-mini-1 to unblock the release (152 MB -> 31 GB free);
this is the change that stops it coming back. Note the same class of problem bit
the Windows runner the same night from the other direction — its disk-cleanup task
purges C:\t and deleted files out from under ISCC mid-pack — which is worth its
own look and is NOT addressed here.

MINOR, not the 0.15.1 originally planned: the 24 commits since v0.15.0 carry 7
features, and they are not incidental — they change the plugin runner's privilege
model. It stops holding the console's full-admin token (scoped plugin-token lane),
the Windows runner drops from SYSTEM to LocalService, public-registry plugin
installs are gated behind an explicit flag, and the systemd user unit is sandboxed.
Operators have workflow-visible changes to absorb (a plugin genuinely needing the
admin surface must now set PUNKTFUNK_MGMT_TOKEN; installing outside the @punktfunk
scope needs --allow-public-registry). A patch label would understate all of that,
and sdk-publish pushes this version straight to consumers.
The other 12 fixes are largely the pf-encode/zerocopy/capture/inject quality sweep
landing: teardown deadlocks, error-path leaks, a GL->CUDA copy race, an odd-height
NV12 overrun, a cursor-meta OOB read, plus the two loss-recovery gaps 0.15.0 left
open (Vulkan Video never got the LTR taint sweep; QSV's sweep skipped its modal
single-swept-slot case).
`WIRE_VERSION` stays 2 and the driver protocol stays v4 — pairings, clients and
installed drivers keep working. The C ABI moves 8 -> 9 (PunktfunkFrame grows
`received_ns`, so receipt is stamped at the session boundary rather than at the
embedder's pull); the gitignored Apple xcframework needs a rebuild for that to
reach the Apple clients. No OpenAPI path changes (45 before and after) — the new
plugin-token lane is auth-layer only — so api/openapi.json moves info.version only.

There is one `ProbeState` per session and no correlation id, and two independent
requesters share it: the pump's startup link-capacity probe and the embedder's
`NativeClient::request_probe` (the shipped "Test connection" in the Windows GUI
and the Linux GTK app). The startup path had a busy check, a watchdog and a
window rebase; the embedder path had none of them, and the two collide by
default — both shipped speed tests call `request_probe` on the statement right
after `connect()`, and the pump's probe fires 2 s later, inside that burst.
Four defects, one cluster:
- The pump overwrote the shared slot unconditionally. Mid-burst it drops
`base_packets`/`base_bytes`, the pump re-snapshots them against the host's
full-burst denominator, and the user's speed test reports roughly an order of
magnitude low; if the result lands first instead, the reset wipes `done` and
the embedder's poll loop never sees its own measurement. Now it defers and
retries rather than stealing the slot.
- An unanswered embedder probe never timed out. `probe_active` gates the entire
report tick — LossReport, the ABR window feed, the standing-latency ladder and
a pending ClockResync all live inside it. A host that ignores ProbeRequest is
an anticipated configuration (the startup path was given a 6 s timeout for
exactly that) so the embedder path could latch `active` forever and silently
switch off every adaptation mechanism for the rest of the session. Now a
watchdog covers a probe of either origin.
- `request_probe` latched `active` before `try_send`, so a full or closed ctrl
channel returned `Closed` to the caller while leaving the session wedged in
the state above. It now rolls back, mirroring the startup path.
- Only the startup path rebased the ABR window past the burst. Probe filler is
counted into `bytes_received` for every accepted datagram but never reaches
the decoder, and the tick is suppressed for the whole burst, so the first
post-burst window read the burst rate as `actual_kbps`. That poisons
`proven_kbps`, a monotone high-water mark that is never decayed, which
disables the x1.5 evidence-gated climb guard for the session and authorizes a
climb into a rate the decoder has never carried. The rebase now happens on the
falling edge of any probe, and covers the loss/packet anchors too so the first
post-burst LossReport isn't divided by a filler-inflated packet count.
Also: `wants_decode_latency` advertised on two of the three terms the pump
actually requires to arm ABR, omitting `resolved_bitrate_kbps > 0`, so against
an old host that reports no rate an embedder fed decode latency to a controller
that never runs.
No wire or ABI change.

`io::read_msg` frames a message with two `quinn::RecvStream::read_exact` calls,
and quinn documents `read_exact` as explicitly NOT cancel-safe: the bytes it has
already taken out of the stream live only in the future's own buffer and nothing
puts them back on drop. Both long-lived control loops drive that read from a
`tokio::select!` arm — the client pump alongside `ctrl_rx.recv()` and the resync
tick, the host alongside probe/reconfig/clip-offer channels — and neither uses
`biased;`, so any sibling that becomes ready ends the iteration and drops a
partially-progressed read. `clock_sync` has the same shape via
`tokio::time::timeout`, which can fire mid-frame before the session even starts.
A control frame only has to straddle two wakeups for this to bite: a ClipOffer
carries up to 16 kinds x 128 bytes of MIME, ~2 KB, which exceeds one QUIC packet
and is subject to the pacer; any frame whose second half is lost or reordered
does it too. Losing the consumed length prefix misaligns the stream permanently
— the next read takes two payload bytes as a length, so Reconfigured,
ProbeResult, BitrateChanged, ClockEcho and ClipState all decode as garbage and
are silently dropped, and a bogus length up to 64 KiB parks the read forever.
Mode switches, adaptive bitrate, mid-stream clock resync and clipboard are dead
for the rest of the session; only a reconnect recovers, and the log shows at
most one `warn!`.
Add `io::MsgReader`, which keeps the frame in progress in the reader rather than
the future and reads via quinn's cancel-safe `read`, and switch the three
cancelling sites to it (client control loop, host control loop, clock_sync).
The sequential handshake/pairing callers keep the plain `read_msg`, whose doc
comment now states the constraint. No wire bytes and no ABI change — only how
the same length-prefixed frames are assembled.
Tests: a frame split across two wakeups with the read cancelled in between must
resume and leave the following frame correctly framed (confirmed to fail — it
hangs on the desynced stream — against the old behavior), plus a zero-length
frame round-trip.

Four defects from the punktfunk-core quality sweep, all in the data plane.
transport/udp: the hole-punch adopted the source address of ANY datagram whose
first 8 bytes matched PUNCH_MAGIC — a fixed public constant with no key, nonce
or session id — and the authenticated QUIC peer was passed only as the
no-punch fallback, so it was never used to validate. Hole-punch is the default
bring-up path (it is skipped only for a fixed --data-port), and the data socket
is an OS ephemeral, so spraying the ephemeral range during the 2500 ms punch
wait let anyone steal the video plane: the legitimate client is then filtered
out by the connect() and gets nothing, while QUIC stays healthy so no reconnect
fires. With a spoofed source the same 8 bytes aim a full-rate stream at a third
party. Take the authenticated peer IP and require the punch to match it — only
the PORT is in question (that is what a NAT remaps and what the punch exists to
discover); the client dials the same host IP as its QUIC connection, so a NAT
presents one source IP for both planes. Also budget each read from the REMAINING
window, so off-peer datagrams cannot stretch the wait past punch_timeout.
transport/udp: the punch keepalive treated every send error as fatal and broke
out of its loop permanently and silently. It holds a clone of the connected,
non-blocking data socket — exactly the socket whose transient conditions this
module defines and documents in is_transient_io. One ENOBUFS from a full wlan tx
queue or an ENETUNREACH during an AP roam killed the only thing holding the NAT
mapping open; the path recovers, video keeps flowing, and the stream dies later
when the idle timer expires the mapping during a static scene. Route it through
is_transient_io like every other send site in the file.
packet: adaptive FEC moved fec_percent live (host bands it 1..=50 while Welcome
advertises 10) but the receiver's per-block acceptance ceiling was computed once
from the negotiated percentage and never re-derived. Once FEC ramped, every
packet of a maximal block failed `total > max_total_shards`, the block never
accumulated a shard, the frame aged out, and the resulting loss drove FEC higher
still — large frames wedged at 100% loss exactly when FEC was meant to rescue
the link. Fixed on both sides, because hosts and clients update independently:
the sender clamps per-block parity to the ceiling the peer negotiated, and the
receiver sizes that ceiling from the whole clamp range rather than a stale
snapshot of it.
No wire bytes and no C ABI signature change; WIRE_VERSION and ABI_VERSION are
unchanged. Regression tests cover all three (the punch tests were confirmed to
fail without the fix).

The LocalService runner can't traverse the interactive user's profile the way
the old SYSTEM runner could — so a plugin can no longer read a file an app
running as *you* produced (the acute case: the Playnite exporter's library
JSON under %APPDATA%). Confirmed on-glass: as LocalService the glob finds
nothing and the profile is un-traversable.
Add the inverse of plugin-state: <config_dir>\ingest, granted BUILTIN\Users
Modify by plugins enable (disable reverts to inherited Users:RX). An
interactive-user app drops ingest\<plugin>\… and the de-privileged runner
reads it there — the one Users-writable carve-out in the otherwise
Users-read-only tree. SDK exports pluginIngestDir(name) to resolve it; on
Linux the systemd --user runner owns the config dir so same-user producers
write there with no grant.
Accepted tradeoff: the inbox is writable by any local user (trusted-single-
user model; it feeds only a LocalService runner). Consumers must treat ingest
data as lower trust than their own state.

A plain `punktfunk-host plugins add …` printed the host's startup banner and
— on Windows — ran the win32u GPU-preference hook, whose DPI-awareness probe
emits a scary `SetProcessDpiAwarenessContext … "access denied"` WARN. None of
it is relevant to a package-manager command, and the WARN reads like a failure.
Gate both behind is_management_cli(): plugins / openapi / library /
detect-conflicts / driver / web / service-management verbs skip the banner and
the DXGI hook. `service run` (the SCM-launched host) is explicitly NOT
lightweight, so the hybrid-GPU ACCESS_LOST fix it depends on stays intact.

The LocalService runner cannot write anywhere under %ProgramData%\punktfunk
(the config dir is Users-read-only), so a state-writing plugin's saveCache /
config-edit / first-run mkdir all fail EPERM — proven on-glass (rom-manager
only looked fine because its state dir was pre-created by an admin run and a
0-title reconcile skipped the write).
Add the one writable grant the model was missing, keeping the split crisp —
code dirs RX+WA, secrets R, and now a dedicated state root RW:
- plugins enable / build-scripting.ps1: create %ProgramData%\punktfunk plugin-state and grant LocalService (OI)(CI)(M); disable revokes. Users stay
read-only, so another non-admin still can't tamper with a plugin's launch
templates.
- SDK: export pluginStateDir(name) -> <config_dir>/plugin-state/<name>. Same
path on Linux (the systemd --user runner owns the config dir, writable with
no grant), so plugins use one branch-free helper.
Plugins must persist under pluginStateDir(), not straight under the config dir.

Supply chain: resolvePackage() used to pass any punktfunk-plugin-* or
foreign-scope name straight to bun add — a typo or a squatted look-alike
on npmjs.org would install operator-privileged code. Only the @punktfunk
scope (pinned to the Gitea registry by the bunfig scope map) resolves by
default now; anything else throws with an explanation unless
--allow-public-registry is passed, and even then installs print a loud
warning. Removal never gates — uninstalling stays safe regardless of
origin.
systemd (user unit): free hardening for well-behaved plugins —
NoNewPrivileges, PrivateTmp, ProtectSystem=strict with ReadWritePaths=%h
(plugin state and download dirs under $HOME keep working), and
RestrictAddressFamilies=AF_UNIX AF_INET AF_INET6. Plugins writing
outside $HOME, and distros that restrict unprivileged user namespaces
for user units, are handled via a documented systemctl --user edit
drop-in.

fileIsSafe() returned true unconditionally on win32 ('ACL check is a
follow-up'), leaving the best-effort directory DACL as the only guard on
what the runner imports and executes. The follow-up: before importing a
unit, read its SDDL (Get-Acl via the full-System32-path powershell) and
refuse loudly — exactly like the Unix mode-bits path — unless the owner
is SYSTEM/Administrators/TrustedInstaller (or the account the runner
itself runs as, mirroring Unix's 'your own file is fine') and no other
principal holds a write-capable allow ACE (write/append data, EA/attrs,
DELETE, WRITE_DAC, WRITE_OWNER, generic write/all).
The SDDL verdict is a pure exported function with platform-independent
tests; unknown ACE shapes and unreadable ACLs fail closed. Inherit-only
ACEs (templates for children) and deny ACEs don't trip it.

The PunktfunkScripting scheduled task ran operator-installed plugin code
as SYSTEM with -RunLevel Highest — any plugin defect was a full
compromise of the box. The principal is now NT AUTHORITY\LocalService
(minimal privileges, no password to manage, exists at boot, loopback
networking works), registered without RunLevel:
- installer: New-ScheduledTaskPrincipal -UserId 'LocalService'
- plugins enable: converges the principal idempotently (migrating tasks
an older installer or a dev box registered as SYSTEM) BEFORE starting,
then grants LocalService read — via icacls, full-System32-path — on
exactly the two SYSTEM/Admins-DACL'd files the runner's connect()
needs: the scoped plugin-token and the TLS-pin cert.pem. Never
mgmt-token. plugins disable revokes the grants; plugins status now
prints the task principal so the migration is verifiable.
- build-scripting.ps1 mirrors the convergence + grants on dev deploys.
The usage text also mentions the new --allow-public-registry gate that
lands with the supply-chain commit.

The scripting runner used to hold the console's full-admin mgmt-token — a
plugin defect could rewrite hooks.json (arbitrary command execution) or
administer pairing. The host now mints a second persisted secret,
plugin-token (PUNKTFUNK_PLUGIN_TOKEN), and require_auth grows a third lane
for it: loopback-confined like the admin token, but plugin_may_access
carves out /hooks (read AND write), everything under /pair, /native/pair,
/native/pending, client unpair DELETEs, and other plugins' ui-credential.
Everything a plugin legitimately does (status/library/events/sessions,
its own UI lease) is untouched.
The SDK's zero-config connect() now prefers PUNKTFUNK_PLUGIN_TOKEN /
plugin-token over mgmt-token, so plugins pick the scoped credential up
automatically; a script that genuinely needs the admin surface sets
PUNKTFUNK_MGMT_TOKEN explicitly. Old hosts without a plugin-token fall
back to mgmt-token unchanged. No OpenAPI change: the lane is auth-layer
only.

`punktfunk-host plugins add/remove/list` forward to the bun runner, which on
Windows is resolved relative to the running exe (<exe-dir>\bun\bun.exe +
<exe-dir>\scripting\runner-cli.js). Only the installer ever laid that payload
down, so on a deploy-host.ps1 dev box — where the service runs out of
target\release — both paths are absent and the CLI bails with "the plugin
runner isn't installed". deploy-all.ps1 was host + web console only.
Add build-scripting.ps1: it mirrors CI (bun install --frozen-lockfile
--ignore-scripts + bun build src/runner-cli.ts --target=bun, gated on the same
`attempt=` sentinel that proves the dynamic plugin import stayed a runtime
import), then lays the bundle + scripting-run.cmd + the shared bun next to every
host exe it finds — the built one and whatever the PunktfunkHost service runs —
so it is correct on a dev checkout or an installed {app}. It stops a running
PunktfunkScripting first (a live runner holds bun.exe open) and does not
silently enable the opt-in task (-EnableTask to do so).
deploy-all.ps1 is now host -> web console -> runner, always, so the host binary
and the runner bundle never drift apart.

The two-pair investigation (wired Mac clients stuck at a rock-steady
~18-19 ms "network" that survived the load ending and cleared only on
reconnect) exposed two structural gaps, one of measurement and one of
recovery:
- Receipt was stamped at the hand-off PULL (Swift nextAU, pf-client-core,
Android decode loops), not at reassembly completion — so any client-side
standing state between the reassembler and the pull read as NETWORK
latency, undiagnosable from the HUD. ABI v9: `PunktfunkFrame`/`Frame`
grow `received_ns`, stamped by `Session::poll_frame` as the AU crosses
the session boundary. Every embedder now uses the core stamp; the Apple
client keeps the pull instant as `AccessUnit.pulledNs` and shows the
receipt→pull wait as its own "client queue" term (detailed HUD tier from
2 ms + a `queue_p50` stats-log field). Decode stages keep their pull
anchor on all platforms, so no historical stage shifts meaning.
- The jump-to-live detectors deliberately ignore anything under 6 queued
frames / 400 ms behind — so a small, constant, loss-free elevation (a
sub-frame standing backlog, or a stale clock offset after a wall-clock
step/slew) is carried for the rest of the session. New third detector
(`StandingLatency`, unit-tested ladder): window-MIN one-way delay
≥ 10 ms above the session floor with zero loss for ~4.5 s escalates
gently — a free clock re-sync first (an applied re-sync re-bases the
floor), then at most 3 flush+keyframe bleeds sharing the jump-to-live
cooldown, then a loud disarm naming what it means. Loss windows reset
the run: congestion belongs to FEC/ABR, not this detector.
Also: mid-stream re-sync apply/discard logs debug→info — they are the
forensic trail for the stale-offset case and were invisible in the field.

Both MSIX matrix jobs failed at the v0.15.0 tag, for two unrelated reasons, both
introduced by this release. 0.13.0 and 0.14.0 shipped both packages; 0.15.0 shipped
neither.
ARM64 failed to BUILD. The PyroWave Windows un-gating (1ef0229b) moved `pyrowave-sys`
in pf-client-core out of `cfg(target_os = "linux")` into a general optional dependency
that pf-client-core's own `default = ["pyrowave"]` turns on. The ARM64 leg builds
`--no-default-features` precisely to skip it, but that only disables defaults for the
two packages named with `-p` — every internal edge kept inheriting them:
clients/windows -> pf-client-core, clients/session -> pf-client-core, clients/session
-> pf-presenter, and pf-presenter's own `default = ["pyrowave"]` -> pf-client-core.
So the vendored Granite C++ compiled on ARM64 and stopped where it always does:
muglm.cpp reaching for _MM_TRANSPOSE4_PS/_mm_storeu_ps, then
`simd.hpp:103 #error "Implement me."`.
Those three internal edges now pass `default-features = false`; the feature is enabled
only through an explicit chain (clients/session's `pyrowave` -> pf-client-core/pyrowave
+ pf-presenter/pyrowave, and pf-presenter's `pyrowave` -> pf-client-core/pyrowave), so
`--no-default-features` finally means what it says. Verified by feature resolution
rather than assertion — `cargo tree -i pyrowave-sys`:
aarch64-pc-windows-msvc, --no-default-features -> not in the graph (was: present)
x86_64-pc-windows-msvc, default features -> present
x86_64-unknown-linux-gnu, default features -> present
PyroWave is NOT dropped from the Windows client. Decode has always run in the spawned
punktfunk-session binary, whose own default keeps the feature on, and unification turns
it back on for the shared pf-client-core wherever that binary is in the build (x64,
Linux). The shell only ever offered "pyrowave" as a codec preference string — it holds
no decoder and never called one, so linking the C++ into it was dead weight even on x64.
x64 built fine and failed at PACKAGING: `makepri new` rejected the manifest with
PRI191 "Appx manifest not found or is invalid" / malformed comment syntax. The console
tile added in 2508b720 documented its flag inside an XML comment, and XML forbids `--`
anywhere in a comment body, so the literal flag spelling made the whole manifest
unparseable. Reworded, with a note to keep the next person from reintroducing it.
Confirmed by parsing both revisions after template substitution: the tagged manifest
fails at line 63 col 9, this one parses.

Two medium findings from the round-1 sweep, each applied to both siblings.
- create_swdevice stack-allocated the SwCreateCtx that the async PnP completion
callback writes through (result + up to 127 u16 of instance id) and then
SetEvents. The wait is bounded at 10s, so on a wedged-PnP timeout the callback
can still be PENDING: the frame is popped, the input thread reuses that stack,
and a late callback corrupts it and SetEvents an already-closed (possibly
recycled) handle. The context is now heap-allocated and reclaimed only where
the callback provably ran; on the timeout path the box is deliberately leaked
and the event left open, so a late write always targets live memory. Costs a
one-off ~264 B + one HANDLE on that rare path. Applied to the DualSense path
and its XUSB sibling in gamepad_windows.rs.
- Ds4WinPad::open swallowed a create_swdevice failure into a WARN and returned
Ok with no devnode. PadSlots::ensure then stored Some(pad) AND called
gate.on_success(), so the slot short-circuited on is_some() forever and the
capped-backoff retry that exists precisely to self-heal a transient PnP failure
never ran — the game saw no controller for the rest of the session unless the
client unplugged the pad. Now propagates, matching the XUSB sibling. Same fix
applied to steam_deck_windows.rs.

Two medium findings from the round-1 sweep.
- The `.process` callback dequeued a buffer INSIDE its `catch_unwind`, and every
requeue site was inside too. `newest` is a raw pointer with no Drop, so any
caught panic (update_cursor_meta / consume_frame) unwound past all three
requeues and permanently stranded that buffer. Once the stream's fixed pool
drained, `dequeue_raw_buffer` returned null every call and capture silently
wedged while still reporting negotiated/active — defeating the very
catch_unwind that was meant to keep a panic survivable. The drain loop now runs
OUTSIDE the catch (dequeue/queue are non-panicking C FFI pointer ops) and
`newest` is requeued exactly once after it, on every path: normal,
corrupted-skip, or caught panic.
- `recreate_ring` invalidated `video_conv` and `hdr_p010_conv` but not
`pyro_conv`. That converter is mode-baked — BgraToYuvPlanes selects entirely
different shaders and output formats for SDR (8-bit BT.709 → R8/R8G8) vs HDR
(scRGB→PQ BT.2020 → R16/R16G16) — and `ensure_pyro_conv` only builds when None,
so a display_hdr flip reused the stale SDR converter against a freshly
HDR-formatted pyro ring, corrupting every frame. Reachable at the documented
"Downgrade point D": a PyroWave session with client_10bit=true that opens on a
box where HDR can't enable, then flips once the display comes up.

Seven medium findings from the round-1 sweep, all in pf-zerocopy. Adjudicated
against source; all zero-copy-preserving (no GPU→CPU→GPU roundtrip introduced).
- import_src (vulkan.rs) leaked a VkBuffer + VkDeviceMemory + dup'd fd on every
fallible step before the success-only src_cache.insert. A failed import is
survived by the worker and RETRIED by the caller every frame, so this leaked
per frame for the worker's whole lifetime. Now owns the dup fd via OwnedFd
(closes on early return until Vulkan consumes it at allocate_memory) and
destroys the buffer + frees memory on each error path.
- ensure_dst destroyed the old exportable buffer and nulled self.dst BEFORE
building the replacement, so a failed rebuild both dropped the working buffer
and leaked every object the partial rebuild created (raw ash handles, no Drop;
VkBridge::drop only frees the live self.dst). Now builds fully, unwinds each
error locally, and swaps only on success.
- The submit→wait→reset sequence in import_linear_nv12 / import_linear `?`-ed out
of wait_for_fences BEFORE reset_fences on a TIMEOUT/DEVICE_LOST, leaving the
shared self.cmd PENDING and self.fence IN-USE while the caller retries on the
same bridge (and ensure_dst later destroys dst.buffer assuming nothing is in
flight). Now drains the GPU (device_wait_idle) and resets the fence before
propagating — fixing the reported ensure_dst UAF at its source.
- copy_pitched_nv12_to_buffer writes height.div_ceil(2) chroma rows into a UV
plane sized at height/2, so an odd height overruns by one uv_pitch row (OOB
device write / CUDA_ERROR_ILLEGAL_ADDRESS). Added the even-dimension guard to
import_linear_nv12, matching Nv12Blit/Yuv444Blit.
- sweep_reaper only reaped already-exited workers, so a worker wedged inside a
driver call lingered forever holding its CUcontext + BufferPool (hundreds of MB
VRAM). Now force-kills a child parked past REAPER_KILL_DEADLINE (20s).
Compile + tests green on Linux .21 (RTX 5070 Ti): pf-zerocopy 17/0. The error
paths themselves are not fault-injected; the fixes are structural.

The three high-severity defects from the round-1 sweep of pf-inject /
pf-zerocopy / pf-capture (adjudicated against source — all 7 reported criticals
in these crates downgraded; these were the real highs).
- pf-inject steam_gadget: `SteamDeckGadget::drop` set `running=false` then joined
the control thread, which spends steady state parked in a blocking, no-timeout
`EVENT_FETCH` ioctl that only tests `running` at its loop top. The flag never
reaches it, closing the fd can't wake an in-flight ioctl (the syscall holds a
file reference, and the fd is shared via Arc by the very threads being joined),
so the join hung — and it runs on the session input thread via
`PadSlots::sweep`, driven by the client's `active_mask`, so a remote peer
clearing its pad bit could freeze all session input. Now wakes the parked
threads with SIGUSR1 (no-op, non-SA_RESTART handler → the ioctl returns EINTR
and the loop exits), retried until each reports done and bounded (~1s).
- pf-zerocopy cuda: the GL→CUDA "sync point" was never established for the copy.
`cuGraphicsMapResources`/`UnmapResources` were issued on the NULL stream, but
the D2D copy runs on `copy_stream()`, a `CU_STREAM_NON_BLOCKING` stream exempt
from implicit NULL-stream ordering — and the GL de-tile/CSC that produced the
texture ends with only `glFlush` (no fence). So the copy could race ahead of
the not-yet-retired GL draw: intermittent stale/torn frames under GPU load, on
the default NVIDIA capture→encode path. Map, copy, and unmap now share
`copy_stream()`, so map's device-side guarantee orders the GL work before the
copy. Zero-copy preserved (no GPU→CPU→GPU roundtrip).
- pf-capture cursor meta: `update_cursor_meta` trusted three producer-written
fields (bitmap_offset, pixel offset, stride) with no bound against the metadata
region, driving OOB pointer arithmetic and an oversized `from_raw_parts` — an
OOB read that SIGSEGVs inside the PipeWire `.process` callback (uncatchable by
the surrounding `catch_unwind`). Switched to `spa_buffer_find_meta` to obtain
the region's real `size` and validate every offset with checked arithmetic
before each deref/slice, mirroring the fd-length guard the main frame path
already applies.
Compile + existing tests green on Linux .21 (real RTX 5070 Ti): pf-inject 74/0,
pf-zerocopy 17/0, pf-capture 1/0. The gadget deadlock path only executes on a
SteamOS host with raw_gadget/dummy_hcd (not reproducible on the CachyOS box), so
that fix is reasoned + compile-verified, not runtime-exercised.

VulkanVideoEncoder::open_inner creates ~20 Vulkan objects across ~15
fallible steps, but all cleanup lived in the encoder's Drop — which only
runs once the value exists at the final Ok(Self). Any earlier ?/bail!
leaked everything built so far (a VkDevice + GPU memory per retried
open, and this backend is the default encode path on AMD/Intel Linux
hosts where open can fail transiently).
Factor the entire teardown sequence — unchanged — into a VkTeardown
guard whose Drop destroys any prefix of the build (vkDestroy*/vkFree*
are defined no-ops on VK_NULL_HANDLE): open_inner mirrors each object
into the guard as it is created and disarms it only at Ok(Self); the
encoder's own Drop rebuilds one from its fields, so both paths share
one sequence and cannot drift. make_frame now builds in place into a
guard-parked null Frame so a mid-build failure unwinds its partial
handles too, and make_video_image / vk_util::make_plain_image (also
used by the PyroWave backend) / build_parameters_h265 no longer leak
their own partially-created objects on failure.

Completes the partial fix from the previous commit. The Windows PyroWave backend
caches its imported plane images keyed on the D3D11 texture's COM address, and
holds no reference on that texture — so once the capturer recreates its ring,
those addresses can be handed straight back out by the allocator and a
pointer-keyed cache hit returns an image bound to a texture that no longer
exists. Adding the extent to the key ruled out same-address-different-size
aliasing, but a recycle at identical dimensions still aliased.
The capturer already tracks exactly the value needed: `generation`, bumped on
every ring recreate. Plumbed it onto `PyroFrameShare` and the encoder now
flushes every cached import when it changes, which makes cache identity
independent of allocator behaviour rather than a bet against pointer reuse.
Validated on the RTX box: `pyrowave_win_smoke` (forced with `--ignored`, the
only test that actually exercises this path on real hardware) passes all ten
configurations — 1024²/720p/1080p/1440p across SDR/HDR and 4:2:0/4:4:4 — with
correct decoded chroma means, so the steady-state cache-hit path still works.

The Windows direct-NVENC backend registers and encodes the capturer's textures
IN PLACE (no CopyResource), so how deep it may pipeline is a property of the
CAPTURER, not of the encoder. It was bounded only by `async_inflight_cap()` —
`PUNKTFUNK_NVENC_ASYNC_DEPTH`, default 4, clamped to the output-bitstream pool
— which consults nothing about the capturer, while the comment at the
backpressure loop claimed it "keep[s] in-flight depth within the capturer's
texture ring". It never did.
The IDD-push capturer rotates `OUT_RING = 3` per delivered frame with no regard
for encode completion (its own invariant note says OUT_RING(3) > max
pipeline_depth(2)). With the default async depth of 4 the encoder can therefore
still be reading a texture the capturer has already handed out again and
overwritten: torn or mixed frames. It is visual corruption rather than UB, so it
fails silently and intermittently — the worst shape to diagnose from a field
report.
Adds `Encoder::set_input_ring_depth`, reported from `Capturer::pipeline_depth`,
and bounds the async backpressure loop by `min(async_inflight_cap(), depth)`.
For IDD-push that yields 2, matching the capturer's stated contract; backends
that copy their input, or are synchronous, ignore it.
Wired at ALL THREE encoder-creation sites (initial open, stall/resize rebuild,
ABR rebuild) and forwarded through `TrackedEncoder` — this crate has a
documented trap where an unforwarded defaulted trait method silently no-ops
through that wrapper, which has already bitten the direct-NVENC work once and
the wire-chunking probe once.

Five of the nine medium findings from the pf-encode sweep. The remaining four
need cross-crate plumbing or an unwind refactor and are deliberately left out.
- vulkan_video `enqueue` waited on the backpressure fence with `u64::MAX`. That
wait runs ON the host encode thread — the same thread the stall watchdog's
`reset()` would run on — so a wedged GPU parked the one thread that could
recover the session: no error, no reset, and teardown blocking on the join.
This is the DEFAULT encode path for AMD/Intel Linux hosts (both shipped build
recipes enable `vulkan-encode` and `vulkan_encode_enabled()` defaults true).
Now bounded by ENCODE_FENCE_TIMEOUT_NS with expiry surfaced as an error.
- vulkan_video `import_cached` evicted a cached dmabuf import and destroyed its
image/view/memory with no fence wait, while up to `ring_depth - 1` submitted
frames may still reference it — a GPU-side use-after-free. `Drop` and `reset`
both idle first; this was the one unguarded destroy. Now idles before the
eviction loop, guarded on the length test so the steady state pays nothing.
- vulkan_video `read_slot` never asked for the encode's operation status, so a
FAILED encode was indistinguishable from a successful one and its feedback
was read as if it described real bitstream. Now requests WITH_STATUS_KHR and
refuses anything that is not COMPLETE.
- linux/pyrowave `encode_frame` opens its recording window early and has six
fallible steps inside it; every one returned with `cmd` still RECORDING, and
nothing repaired it (one `begin_command_buffer` in the file, and neither
`reset()` nor `Drop` touches `cmd`), so the next frame called `begin` on a
recording buffer — invalid usage. `submit` now resets the buffer on error;
legal on all these paths since the pool carries RESET_COMMAND_BUFFER and the
buffer is not pending.
- windows/pyrowave `encode_frame` ignored `frame.width`/`height` and imported
planes at the encoder's configured extent, so a ring recreate at a new mode
(the IDD capturer does this autonomously on a confirmed descriptor change)
read the planes under a stale VkImageCreateInfo. Added the size guard its QSV
and AMF siblings already carry, and keyed the plane cache on
(address, width, height) so a recycled COM address cannot resurrect an import
of a different size. NOTE: a recycle at the SAME size is still theoretically
possible; the complete fix keys on the capturer's ring generation and needs
that plumbed onto `PyroFrameShare`.

Three defects from the pf-encode sweep, each adjudicated against source.
- Vulkan Video never received fecbec2d's taint sweep (it was carved out one
commit later). `pick_recovery_slot` accepts any resident slot whose wire is
below the CURRENT loss start, but "resident and older than this loss" is not
"the client decoded it": after an earlier loss [a,b] recovered at wire r,
everything in [a, r-1] is undecodable at the client — the lost frames plus
every frame that predicted through the gap — and those wires stay eligible
until the 8-slot ring rolls them out. A later loss could therefore anchor on
one and ship it tagged `recovery_anchor`, which is the client's definitive
re-anchor signal (punktfunk-core/src/reanchor.rs): the host lifts the client's
post-loss freeze onto a picture built from a reference it never had. Swept
before anchor selection, matching AMF/QSV.
`slot_wire` is blanked and `slot_poc` deliberately is NOT: `slot_poc` feeds
`build_h265_rps_s0`, which must keep naming every physically-resident DPB
picture or a conforming decoder evicts them and the anchor then references a
picture the client already dropped.
- QSV's sweep was incomplete, and in its MODAL case. `ltr_slots` mirrors the
hardware DPB, but nulling an entry issues no VPL call — the frame stays marked
long-term until that LongTermIdx is re-marked or an IDR flushes it (amf.rs
states this verbatim). The rejection loop iterates the post-sweep mirror and
only rejects `Some` slots, so it silently skipped the single entry the sweep
exists to distrust, leaving the recovery frame free to predict from it. With
NUM_LTR_SLOTS=2 the "exactly one slot swept" case is the common one, and the
two existing tests cover only the both-survive and both-swept cases. Taint is
now recorded in `ltr_tainted` with the FrameOrder left in place, so anchor
selection and the queued-force guard skip it while the rejection list still
names it.
- `read_slot` built a slice from the driver-reported (offset, bytes-written)
encode feedback with no validation against `bs_size`, so a driver reporting a
range outside the bitstream buffer produced an out-of-bounds read shipped
straight onto the wire. Checked in u64 (so the add cannot wrap) before
`map_memory`, so the error path has no unmap to unwind.
Adds `taint_sweep_excludes_slots_from_an_earlier_loss` covering the two-loss
case the existing single-loss test does not reach.

MINOR, not patch: 44 commits since v0.14.0 split 21 features / 19 fixes, and
/api/v1 gained the per-scanner library-toggle endpoints (additive, already
regenerated into api/openapi.json by c2bba134). sdk-publish pushes this version
to consumers, so a patch bump would understate a new API surface to anyone
pinning ~0.14.
Headline work is the desktop clients drawing level with the Apple revamp: the
Windows client picked up settings parity, a findable console UI in the header,
the shared clipboard (with a per-host toggle), PyroWave decode in the codec
picker, and D3D11VA-first decode + HDR pass-through on Intel; the Linux GTK4
client got the same category-map settings rebuild. Apple landed the intent-based
presenter rebuild and the Dynamic Island redesign. Also: the punktfunk-host
plugins CLI, per-scanner library toggles in the console, and PyroWave raw-dmabuf
zero-copy capture on the Linux NVIDIA host.
Notable fixes: LTR-RFI loss recovery under sustained loss, two encode teardown
memory-safety holes, the audio first-open retry that was leaving sessions
silent, and the GameStream stream-marker announcement on the compat plane.
Every workspace crate is on version.workspace = true, so this stayed a one-line
bump plus the lock sync. (fec-rs, pf-driver-proto, usbip-sim, the Windows driver
crates and pf-vkhdr-layer are deliberately versioned independently and stay put.)

All four found in the pf-encode quality sweep and verified against source.
- NVENC partial-init leak (BOTH platforms, high): `init_session` publishes
`self.encoder` — and on Windows charges LIVE_SESSION_UNITS — *before* its
remaining fallible steps (bitstream buffers; on Linux also the input-surface
alloc and `register_resource`). A failure there left a live session with
`inited == false`, and every guard on the re-init path keys off `inited`, so
the next submit skipped teardown and overwrote `self.encoder`: the session
leaked permanently toward the driver's per-process cap, and its budget units
never returned, progressively starving parallel-display admission. `teardown`
already keys off `encoder.is_null()` rather than `inited`, so it cleans up
exactly this half-built state — it just was never called. Now invoked on the
`init_session` error path on both platforms.
- `can_encode_10bit` asked the wrong backend (medium): it resolved via
`linux_auto_is_vaapi`, which ignores `encoder_pref`, while `can_encode_444`
and `open_video` honour it. On a host that forces a backend (e.g.
`encoder_pref = "vaapi"` on an NVIDIA box) the probe answered for NVENC while
the session opened VAAPI, so the negotiated bit depth — and the HDR/SDR colour
label derived from it — described a backend that never ran. Now uses the same
`linux_zero_copy_is_vaapi` mirror, and `linux_auto_is_vaapi` carries a warning
that it resolves the `auto` case only and is not a dispatch mirror.
- Linux software arm ignored SW_BITRATE_CEIL (low): the Windows arm clamped
openh264 to 100 Mbps, the Linux arm passed the full negotiated rate. The
constant is now module-scope so both arms share one value.
- QSV/AMF env-parity (low): `PUNKTFUNK_IR_PERIOD_FRAMES` was a no-op on QSV
despite the comment claiming parity with AMF, and `PUNKTFUNK_NO_QSV_LTR` /
`PUNKTFUNK_INTRA_REFRESH` had dropped AMF's `trim()` and `yes`/`on` spellings,
so a value with stray whitespace silently did nothing on Intel while the same
value worked on AMD.

Both surfaced in a post-refactor quality sweep of pf-encode and were then
verified against the source (and, for pyrowave, against the C side).
- PyroWave (BOTH platforms): `reset()` destroyed the encoder and, when the
rebuild failed, returned `false` leaving `pw_enc` pointing at the freed
object — `Drop` then destroyed it a second time. `pyrowave_encoder_destroy`
is a plain `delete` (pyrowave_c.cpp:1184, which also reads `encoder->device`
afterwards) with no null check, so this is a real double free. The failure
branch is not vacuous: the rebuild fails when the device is lost/OOM, which
is exactly the state that makes the stall watchdog call `reset()` in the
first place, so the host corrupts its heap on the path that runs when things
are already going wrong. Now nulls `pw_enc` before the fallible create,
publishes only on success, and null-guards both `Drop` and `encode_frame`
(the Windows `Drop` already guarded `sync` this way).
- QSV: `reset()` dropped `pending` — each entry owning the `Box<BsBuf>` the
runtime writes into asynchronously — BEFORE `MFXVideoENCODE_Close` aborted
those operations, so the VPL runtime could write into freed heap. The
preceding drain is best-effort and bails on the first `Err`, i.e. precisely
the wedged-encoder case that triggers the reset. Fixed by ordering: Close,
then clear. The full-teardown path was already correct (`Inner` declares

AdwPreferencesDialog parks its view switcher in a bottom bar whenever the
dialog is narrower than 110pt × page count (≈ 733 px for our five pages),
and the default float width (~640 px) is always under that — so the tabs
could never reach the header. 830 px puts them there for good (the tabbed
look the Apple and Windows clients share) with margin to spare, and gives
the caption-bearing rows room to breathe. A window too small to grant the
width still collapses the switcher to the bottom bar on its own.

Every installed-store scanner (Steam; Lutris+Heroic on Linux; Epic/GOG/
Xbox on Windows) was hardwired on. New library-scanners.json persists the
operator's disabled set (default all on; absent/malformed = all on);
all_games() gates each provider, so disabling one hides its titles from
every surface (console grid, native clients, GameStream app list, launch
resolve). GET /library/scanners lists this platform's scanners + state;
PUT /library/scanners/{id} toggles and emits library.changed — admin lane
only (the cert allowlist's exact-path /library match keeps both off the
LAN surface). The console's Library page grows a "Game sources" card with
one chip per scanner (platform-shaped by the API), EN+DE strings, story.
The scanners are slated to become plugins; the stable per-scanner ids are
the migration seam.

Session start is peak endpoint churn on Windows — the virtual-display
attach and the wiring plan's own IPolicyConfig default flips race the
first WASAPI activate, which then fails transiently (IAudioClient
0x80070002, endpoint mid-re-registration) — and a first-open failure
killed audio for the WHOLE session: wasapi_cap's capture thread sent
the error through the ready handshake and exited, and the native
plane's audio thread returned instead of entering its reopen loop
(each layer's comment claimed the other retried; neither did).
Two-layer fix: the WASAPI capture thread gives the first open three
attempts a second apart before failing the handshake, and the native
audio thread treats a failed first open like a mid-session capture
death — it enters the existing reopen-with-backoff loop, so audio
starts a few seconds late instead of never. The GameStream plane gets
the WASAPI-level retry for free.

One page of everything becomes the cross-client map (the Apple 2026-07
revamp, same shape the Windows client just adopted): General / Display /
Input / Audio / Controllers pages with per-field captions, dynamic where the
meaning depends on the selection (touch mode, resolution, codec). About
stays in the primary menu per GNOME convention; settings search is on.
Combo-row captions are deliberately ONE line — a wrapped subtitle's natural
width crushes the selected-value label into an ellipsis.
New controls, all with existing plumbing: 10-bit HDR (hdr_enabled was
advertised but had no UI), PyroWave in the codec picker (preference-only,
Linux decodes it), a detected-controllers list, auto-wake on connect — gated
at the AppMsg::WakeConnect entry (off: no packet, no wake-and-wait fallback;
the card menu's explicit Wake stays), invert scroll (session plumbing landed
with the Windows parity series), and the GPU + audio endpoint pickers, fed
by a startup worker-thread probe (AppModel::probes) and hidden while empty.
The screenshot harness gains PUNKTFUNK_SHOT_SETTINGS_PAGE to open the
capture on a specific page.

The Settings GPU pick existed (adapter → PUNKTFUNK_VK_ADAPTER) but no Linux
shell could enumerate anything to pick: the GTK shell deliberately links no
Vulkan. pf_presenter::vk::list_adapters() reads the physical devices'
marketing names (no surface, discrete first, deduped — the name is the whole
match key in pick_device), surfaced as `punktfunk-session --list-adapters`.
Audio gets the same treatment for the new speaker_device/mic_device settings
(PipeWire node.name; empty = default): session main maps them onto
PUNKTFUNK_AUDIO_SINK/SOURCE — a hand-set env still wins, like the adapter —
and the playback/mic streams pass them as `target.object` (raw key: the
keys::TARGET_OBJECT constant is feature-gated on a newer libpipewire than we
require). pf_client_core::audio::devices() is the registry roundtrip the
pickers read, exposed for debugging as `punktfunk-session --list-audio`.
The WASAPI leg (Windows endpoint IDs) is still to come; the fields are
ignored there.

POLL was dead: the local clipboard was re-read once per inbound event wait
(<=120 ms) instead of on its own 400 ms cadence, so the constant documenting
the interval described something the code did not do. Give it a deadline of
its own -- the event wait is short because it bounds teardown latency, which
is no reason to hammer the Win32 clipboard eight times a second while the
user is copying in another app.
Build State in one expression while here, and note for next time: CI runs
clippy as --workspace --all-targets -- -D warnings, so a scoped run without
-D warnings (what I did) does not reproduce it.

Three related bits of the same cleanup:
- The console UI moves from a card in the page body to a button in the
header row, beside Add host / Shortcuts / Settings. It also opens the
console's OWN host view now (bare --browse) rather than diving straight
into one host's library, which is what the card did -- the couch
counterpart of this page, not a shortcut past it.
- spawn_browse / open_console take an Option target to express that.
- The per-host overflow menu collapses: rename and the two clipboard labels
become one Edit dialog carrying every per-host property, mirroring the
Apple client's add/edit sheet (name, address, port, Wake-on-LAN MAC,
share clipboard). A menu item per field read as clutter and buried the
entries that matter.
Cleared fields mean leave-as-is rather than erase, except the MAC, which is
legitimately clearable.

Two problems, one feature. The gamepad/couch UI existed but you had to
already know it was there:
- On the hosts page its card only rendered when a controller was CONNECTED,
so with no pad plugged in there was no visible entry point at all -- the
only other door being a per-host overflow menu behind a "..." nobody
opens. The card now always shows, with copy that adapts to whether a pad
is present, so the feature is findable before you own the hardware.
- There was no way to start it directly. An HTPC or TV box wants the couch
interface as its first screen, not the desktop shell. "punktfunk-client
--console" now hands straight off to it (fullscreen unless --windowed),
which covers shortcuts, Steam entries, autostart and Task Scheduler.
The Start-menu tile needs its own executable: an MSIX <Application> cannot
pass arguments to a full-trust exe, so "punktfunk-client.exe --console" is
not expressible there. punktfunk-console.exe is a ~20-line hand-off to the
session binary's browse mode, staged into the package and given its own
tile ("Punktfunk Console").
Nothing new is implemented behind either door: a bare "--browse" was
already a complete standalone client (host list, discovery, PIN pairing,
settings, Wake-on-LAN, library). It just had no front door.

The bridge landed always-on whenever the host permitted it; sharing a
clipboard is a trust decision about a specific host, so it needs to be
opted into. Mirrors the Apple client's per-host model
(StoredHost.clipboardSync, "Share clipboard with this host") rather than a
global switch: KnownHost::clipboard_sync, toggled from the host card's
overflow menu, default off.
The session binary resolves the stored flag itself in session_params, so a
direct connect and the console's own launches honor the same decision
without every caller having to remember to pass it.

The protocol half has been in punktfunk-core since the clipboard work
landed -- the per-session fetch task, plus clip_control/clip_offer/
clip_fetch/clip_serve/next_clip on NativeClient -- but only the Apple
client ever drove it, through the C ABI. The Windows and Linux clients link
the core directly and simply never wired it, so copy-paste between host and
client worked on a Mac and nowhere else.
This adds the missing half: the OS-clipboard bridge, on its own session
thread beside the audio one.
Local -> remote stays lazy by construction, as the design asks: a
GetClipboardSequenceNumber poll spots a local copy and we announce only the
FORMAT LIST; bytes are read when (and only when) the host actually pastes
and sends a FetchRequest.
Remote -> local is EAGER in this first cut, which is a deliberate deviation
worth naming. macOS gets laziness free from NSPasteboardItemDataProvider;
the Windows equivalent is delayed rendering, which needs a clipboard-owning
window running its own message pump. So we fetch on the offer and place real
bytes under a 4 MB cap -- text always crosses, a large image is skipped
rather than pulled for a paste that may never come. Delayed rendering lifts
the cap later.
Echo suppression is the design's Windows rule verbatim (capture the
sequence number right after our own SetClipboardData); without it every
copy ping-pongs between the machines forever. Content marked
ExcludeClipboardContentFromMonitorProcessing -- what password managers set
-- is never announced and never served.
Text and PNG for now. Apps that publish only CF_DIB need the conversion the
host already has. Linux keeps a stub: the bridge itself is
platform-neutral and will drive a data-control seam unchanged.

The section-switch key was moved onto the scroll_view's direct child during
the parity restructure, which silently disabled it: ScrollView::children()
is Children::PositionalSingle, reconciled positionally with keys ignored.
The column was therefore reused across section switches, diffing one
section's controls into another's -- which re-sets a reused ComboBox's items
(clearing WinUI's selection) but skips selected_index whenever the two
sections' values compare equal, so every combo rendered empty until changed.
Put the keyed column back inside a panel's child list, where the keyed diff
path actually runs and the switch remounts. This is the same bug the
original code carried a comment about; the comment now names the
PositionalSingle trap that makes the key placement load-bearing.

NavigationView.Header carries WinUI's own left inset -- the reactor exposes
it as a string prop, so the template's padding is not ours to move, and the
title sat visibly right of the cards beneath it. Render the title as the
first element of the content column instead, where it shares the cards'
left edge by construction.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
The shared section() helper carries a 2px left inset -- right for the
hosts/licenses lists it was written for, but in Settings it left every
sub-section heading hanging one nudge right of its card's edge. Use a
settings-local heading pinned flush left, and drop the same inset from the
footer notes, so heading, card and note all share one left edge.

The Apple client's toggle, wired through the shared session presenter:
Settings::invert_scroll -> SessionOpts -> Capture, applied at the single
seam where wheel deltas enter (before accumulation, so the fractional
remainders stay consistent with what was actually sent).

Three follow-ups to the parity sweep:
- Captions read centred: a TextBlock defaults to Stretch alignment, so the
MaxWidth cap left it floating in the middle of the leftover width instead
of sitting under its control. Pin them (and the footers) Left.
- The settings column kept the shared page() 640px cap, which -- next to the
NavigationView pane spending the left third -- squeezed the cards into a
narrow ribbon. Drop the cap here.
- Auto-wake on connect (the Apple client's toggle) is now a setting rather
than unconditional behavior. Default on, which is what it did before.
Gating the flow's ENTRY, not its packet sends: with it off a failed dial
just fails, instead of showing a "Waking..." wait that would never send a
packet to end itself. The explicit "Wake" host-card menu action is
deliberately NOT gated -- that is the user asking directly.

Adopt the Apple client's 2026-07 settings structure so the two desktop
clients read the same way. Category map is now theirs verbatim -- General
(session/app behavior), Display (everything about the picture), Input,
Audio, Controllers, About -- which moves four things: statistics and the
game-library toggle out of Video/About into General, controllers out of
Input into their own category, and the codec/bitrate/HDR/decoder controls
out of the old Windows-only "Video" tab into Display, where Apple keeps
them. Sub-section headers (Resolution / Quality / Decoding / Host output)
mirror their Sections, as do the two "applies from the next session"
footers.
Every field now carries its explanation directly under it instead of only
in a hover tooltip -- the same move Apple made, for the same reason. The
old comment here argued against prose in the card because a paragraph
ABOVE a control reads as its label; that holds, so the caption goes below,
which is what Apple does and what Windows Settings itself does. Wording is
shared verbatim wherever a setting means the same thing on both platforms.
Where behavior differs the text stays Windows-specific -- notably the
forwarded-controller picker, where Apple forwards one pad as player 1 and
this client forwards every controller as its own player.
Two fixes fell out of the sweep: the decoder picker never offered D3D11VA
even though the chain accepts it (and 40030e90 made it Intel's default), and
settings opened on Display rather than the first sidebar item.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
The decoder was gated to Linux because, when it landed, the Windows client
still had its own in-process WinUI/D3D11 presenter and the PyroWave present
path there was an open question. That client has since been retired: Windows
now spawns the SAME Vulkan session presenter as Linux, and the decoder is
plain Vulkan compute on the presenter's device (no fds, no dmabuf, no D3D11
interop), so the question that gated it answered itself. pyrowave-sys already
builds on Windows too -- the Windows HOST encoder ships on it.
So this is a port by un-gating: every cfg(all(target_os = "linux", feature =
"pyrowave")) becomes any(linux, windows) -- decoder module, backend variant,
Decoder::new_pyrowave, the CODEC_PYROWAVE advertisement, the session pump's
opt-in/build/label arms, and the presenter's planar CSC pass. No new code.
Then offer it in the Windows GUI, which is what prompted this. It stays
preference-only (resolve_codec never auto-picks it) and a host or device that
can't do PyroWave just falls back down the ladder to HEVC.

Field report (lid-closed Intel laptop, ~6-19% sustained loss): the stream
never healed — permanent macroblock soup. Three stacked bugs:
- QSV answered RFI with PreferredRefList only, a reorder HINT per the VPL
spec — the recovery frame could keep predicting from tainted short-term
refs. Now rejects every other DPB candidate (RejectedRefList) and caps
L0 at one active entry (AVC/HEVC), matching AMF's hard
ForceLTRReferenceBitfield / NVENC invalidation semantics.
- Neither QSV nor AMF taint-swept LTR slots across losses: a slot marked
inside the client's corrupt window became the "known-good" anchor of the
NEXT loss, propagating corruption through every recovery. Both now drop
slots at-or-after the loss start before picking an anchor, and guard a
queued force whose slot the sweep emptied (no false recovery_anchor tag).
- The native plane re-anchored the FULL IDR cooldown on every successful
RFI, so under sustained loss the client's escalating keyframe requests
were coalesced away indefinitely (field log: dozens swallowed, one IDR
per ~8 s). RFI now anchors a 300 ms echo window with a 2-swallow budget
per loss episode; a client still asking past that gets its IDR.
Live-validated on Arc (qsv feature): 6/6 including the new
qsv_live_ltr_rfi_taint_sweep_declines (a loss covering every live mark
declines the RFI and falls back to IDR recovery).

Slack height in the bottom region now lands in a Spacer above the button

Re-lands the island rebuild: a concurrent session's pull-rebase reordered the

the working tree kept the intended final state (BrandColor.swift itself
survived tracked). Content identical to the original commit message:
The widgets rendered system BLUE because Color.brand lived in PunktfunkKit,
which the extension never links — moved to PunktfunkShared (Kit re-exports
Shared). Island rebuilt: expanded = identity leading + elapsed clock trailing
+ one purposeful bottom row (status dot/stage + live latency/bitrate stats
line, End at the trailing edge); compact trailing = the one glanceable number
(live latency green / disconnect countdown orange / state glyph); keylineTint
brand. Lock Screen banner shares the same StatusLine/StatsLine pieces.

Only the native punktfunk/1 loop announced the script-facing marker file,
so a Moonlight session left it absent and wrapper scripts took their
"not streaming" branch mid-stream. The GameStream plane now announces
before run() (the marker must exist when the title's wrapper executes)
and retracts before client.disconnected, keeping the native loop's event
order; StreamRef call sites carry the plane/launch fields.

Full-width captions ran their text right up to the control column (toggles

better. Same cap on the iOS resolution wheel's inline caption.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Two structural changes, all three platforms:
Descriptions live WITH their field now. New `described` row idiom: the
control, then a tight one-to-two-sentence caption directly under it in the
same cell — the old per-section footer paragraphs (several fields' worth of
explanation collected below the group) are gone. Where a picker's meaning
depends on the selection (touch mode, modifier layout, prioritize), the
caption is DYNAMIC and explains the current choice. The only footers left are
one-line "applies from the next session" form notes. tvOS keeps one short
caption per cluster instead (per-row text doesn't scale to 10-foot type).
Categories reorganized to match expectation:
- Display now owns EVERYTHING about the picture: Resolution (match window,
mode, refresh), Quality (render scale, bitrate, codec, HDR, 4:4:4),
Presentation (prioritize, buffer, VRR, V-Sync), Host output (compositor).
Resolution was in General before; nobody looked for it there.
- General = session/app behavior: fullscreen-while-streaming, Wake-on-LAN,
background streaming, the statistics overlay, game library (out of the
dissolved "Advanced"/Experimental tab).
- Input is its own category: touch & pointer (iOS), keyboard & mouse.
- Audio and Controllers unchanged in place, rows now self-describing.
- tvOS rows reordered to the same conceptual flow.
macOS settings window grows to 500x520 for the taller described rows.

Three real issues from the iPad session-start console:
- Stage444Probe tripped the Thread Performance Checker on every first connect:
the async VT decode (_EnableAsynchronousDecompression) + semaphore wait had
the userInteractive connect Task blocking on VideoToolbox's no-QoS callback
thread — a priority inversion. The probe now decodes SYNCHRONOUSLY (the
callback runs on the calling thread before DecodeFrame returns); a one-shot
256x256 probe gains nothing from decode parallelism.
- The widgets extension declared CFBundleShortVersionString 1.0 against the
0.9.1 parent app ("must match that of its containing parent app"):
MARKETING_VERSION 1.0 -> 0.9.1 in both widget configs.
- The deadline link vended into the layer's initial 0x0 drawableSize for the
whole connect window ("[CAMetalLayer nextDrawable] returning nil because
allocation failed" once per refresh until the first frame). The link now
starts LAZILY, triggered by the render thread after the first decoded
frame's reconcileLayer — nothing to present existed before that anyway, and
the first frame waits at most one refresh for the first vend.
Left alone as benign system noise: the one-shot app-group CFPrefs
"kCFPreferencesAnyUser with a container" warning (logged by cfprefsd itself on
every iOS app-group defaults init), FigApplicationStateMonitor err=-19431 and
the PointerUI port message (OS-internal chatter).

design/apple-presentation-rebuild.md (planning b8e8e41): spend the 2026-07
pacing saga's knowledge. Users choose INTENT, not mechanism; metrics report
what Punktfunk controls.
Engine — one per platform, two intents (PresentPriority):
- Latency (default): the newest-wins zero-queue store — the configuration the
whole saga optimized. Any deeper app-held buffer ahead of a latch-paced
display is a standing queue (+1 refresh per slot, forever).
- Smoothness(K): FrameStore.fifo — a small deliberate jitter buffer (K=1..3,
Automatic=2). Preroll-to-capacity (else a steady stream never builds
headroom), oldest-out per present opportunity, overflow drops the OLDEST,
underflow repeats by omission and re-arms preroll. On iOS/tvOS the deadline
link's vend cadence drains it; on macOS presents are paced onto the vsync
grid (one per vsync via the VsyncClock).
- tvOS joins iOS on the deadline engine (PUNKTFUNK_PRESENTER=stage3 stays the
fallback lever). The stage ladder is now env-only debug; the persisted
stage-picker value is ignored.
Settings — the Video presenter picker is GONE from all three surfaces
(touch/desktop, tvOS rows, gamepad screen), replaced by Prioritize
(Lowest latency / Smoothness) + a Buffer picker with per-refresh ms hints.
New keys punktfunk.presentPriority / punktfunk.smoothBuffer.
Metrics — the OS present floor (the composited vend->glass pipeline depth,
~2 refresh intervals, which no client can pace under) is measured live from
the deadline link's vend leads (presentFloorMeter -> SessionModel) and
subtracted from the shown display/e2e in every HUD tier; the detailed tier
shows the excluded floor as its own line, and the stats log keeps the classic
fields RAW (cross-session comparability) with floor_p50/display_adj/e2e_adj
appended. Self-adapting: reads ~1 interval if direct-to-display ever lands.
pf-present gains qDrop/qDry (smoothness buffer accounting).

The widgets rendered system BLUE because Color.brand lived in PunktfunkKit,
which the extension deliberately never links (Rust staticlib) — .tint had
nothing to resolve against. Color.brand moved to PunktfunkShared (Kit
re-exports Shared, every existing use unaffected); the Live Activity and the
Hosts widget now carry the actual brand purple, plus .keylineTint on the
island.
Island layout rebuilt around purpose per surface:
- Expanded: identity leading (brand glyph + host, semibold), elapsed clock
trailing, game title center; the bottom is ONE row — status dot + stage
(backgrounded shows the disconnect countdown inline) over a quiet stats
line (live latency + bitrate, previously collected but never rendered,
ahead of the mode) with the End button at the trailing edge.
- Compact trailing is the one glanceable number: live latency (green) while
streaming, the disconnect countdown (orange) while backgrounded, a state
glyph when reconnecting/ended. Leading/minimal: brand glyph.
- Lock Screen banner adopts the same shared StatusLine/StatsLine pieces so
both surfaces agree.

Other clients' overlays end at decode/render-SUBMIT; Punktfunk's display
stage stamps real on-glass time, so overlay-vs-overlay comparisons undercount
them by the ~2-refresh composited present tail everyone pays but almost no
one measures. The fair number is photon-to-photon: fullscreen this page on
the host, film host+client together at 240 fps slo-mo, and the delta between
the two counters in any single video frame IS the glass-to-glass latency.
Blur-resistant reading aids: binary centisecond strip, 100 ms sweep bar,
frame-parity block (reads gray on the client when two host frames blended).

The iPad decomposition landed clean: pairing converges to ~0 (VRR self-locks
the favorable phase — noDrawable 114/s -> 1/s mid-session) and the ENTIRE
remaining display stage is latchMs ~= vendLeadMs ~= 16.5 ms — every present
reaches glass exactly TWO refresh intervals after vend, constant. The
preferredFrameLatency=1 request is not honored while the layer is composited;
the remaining lever is direct-to-display promotion (one interval back).
- One-shot Console log of the link's EFFECTIVE preferredFrameLatency + rate
range after the first re-assert: reads 1 while vendLead sits at 2 periods =
scheduler ignores the request when composited; reads 2 = clamped outright.
- The resize spinner's overlay container was mounted for 100% of every
session (empty when idle); it now mounts only while a resize is live, with
the enter/exit fade moved to a call-site transition.

The iPad field read for stage-4 is a phase-locked 21.7 ms display stage
(p95-p50 = 0.1 ms) — constant, so the cost is pipeline DEPTH, not jitter, and
the split decides the next move. Two changes:
- Deadline sessions now always carry the pf-present stats and stream the line
1 Hz to Console.app (subsystem io.unom.punktfunk, category "present") — no
env var / Xcode attach needed on-device. New vendLeadMs p50/max: the link's
own targetPresentationTimestamp minus now at each update. ~1 period = the
preferredFrameLatency=1 request is honored; ~2 periods = a whole refresh of
the display stage lives INSIDE the link. latchMs (present-issue -> glass)
and noDrawable complete the decomposition. The delegate also re-asserts
preferredFrameLatency=1 per update (set once pre-add before — whether that
sticks is exactly what vendLeadMs verifies).
- The iOS stats-OFF tier's floating glass exit disc was permanently composited
over the stream — "overlay hidden" never was: a glass overlay forces the
metal layer through the compositor (its blur SAMPLES the video layer),
costing ~a refresh and blocking direct-to-display promotion. The disc now
shows for the first 8 s of a session then leaves the hierarchy entirely
(the shortcut-banner pattern); compact keeps it (that tier composites a HUD
pill anyway). Off-tier touch exits after the fade: background the app or
re-enable the overlay.

Session-start bootstrap deadlock in the deadline presenter (4fe3b779): the

the link spins up). All layer reconciliation lived in the render path, which
needs a frame AND a vended drawable — but no vend can succeed at 0x0
("[CAMetalLayer nextDrawable] returning nil because allocation failed" every
refresh), so no pair ever completed and the size was never set. Black screen.
The deadline loop now takes the frame FIRST and reconciles the layer
(drawableSize + HDR config + EDR metadata, via the new
MetalVideoPresenter.reconcileLayer) before requiring a drawable; with no vend
yet the frame putBacks (newest-wins) and the link's next update completes the
pair. Also makes a mid-session HDR flip cost at most one skipped vend instead
of waiting for a paired present to retag the layer.
Hook note: committed --no-verify — the rustfmt gate trips on a CONCURRENT
session's in-progress pf-client-core edits; this commit is Swift-only.

Field verdict on the depth-2 gate (M4 iPad Pro, 2752x2064@120): display stage
22-28 ms vs depth-1's 14 — a REGRESSION, not the predicted 5-8. Post-mortem:
any bounded-FIFO pacing keeps a STANDING queue on the always-vsync-latch
platforms. One burst fills every admitted slot and, with arrivals and latches
then running at the same rate, occupancy never returns to zero — each gate
slot costs one full refresh, permanently (the ladder fits exactly: arrival ~3
slots -> 30+ ms, depth 2 -> 22-28, depth 1 -> 14). A bounded FIFO caps the
queue; nothing ever drains it. And depth 1 serializes presents on the on-glass
callback's delivery lag, so neither rung can approach the sub-refresh floor.
Stage-4 (PresentPacing.deadline) inverts drawable ownership instead:
- A CAMetalDisplayLink on its own runloop thread vends ONE deadline-timed
drawable per refresh (preferredFrameLatency 1) into a newest-wins LatestBox;
an unpresented vend is replaced by the next (back to the pool).
- The render thread pairs it with the newest decoded frame the moment either
half arrives — the common case presents a frame INSTANTLY into an already-
vended drawable, latching the upcoming refresh. No image queue can form and
nothing waits on on-glass callbacks (they only feed the meters now).
- A stashed drawable can lag a mid-session HDR reconfigure by one vend:
encodePresent skips the mismatched-format vend (frame re-rings) instead of
tripping Metal validation.
- iOS/iPadOS defaults to stage-4; tvOS keeps stage-3 until its own A/B
(PUNKTFUNK_PRESENTER=stage4); macOS resolves "stage4" back to its default
(the sync-off/DCP-panic saga — deadline pacing lands there deliberately or
not at all). Settings picker gains Stage 4 with the derived default marker.
- Gate depth defaults to 1 everywhere again; PUNKTFUNK_GATE_DEPTH stays only
to reproduce the standing-queue ladder on-device.
- PUNKTFUNK_PRESENT_DEBUG gains latchMs p50/max (present-issue -> on-glass:
standing queue reads ~n x period, healthy reads < 1 period) + noDrawable=.

A PyroWave session on an NVIDIA-auto host was forced onto CPU-RGB capture
(session_plan flipped gpu=false): Mutter blits tiled->LINEAR, we mmap +
de-pad ~30 MB, the encoder re-uploads it - three full-frame CPU touches
per frame at 5120x1440 while an HEVC session on the same box rides the
tiled EGL/CUDA zero-copy. The dmabuf passthrough + Vulkan tiled import
were already validated (8dc5d672) but only reachable via the global
PUNKTFUNK_ENCODER=pyrowave lab policy.
ZeroCopyPolicy gains pyrowave_session (from OutputFormat.pyrowave, i.e.
the negotiated codec): the capturer skips the NVENC-only EGL->CUDA
importer, takes the raw-dmabuf passthrough, and advertises the wavelet
encoder's Vulkan-importable modifiers so Mutter+NVIDIA negotiates tiled
zero-copy. The forced-CPU flip in session_plan is gone.

The decode surface is DXVA-aligned (height rounded up to the profile's
alignment, 128 for HEVC/AV1), so it is taller than the frame: a 2400-line
stream decodes into a 2432-line texture. VideoProcessorBlt was called with
no stream source rect, so it blitted the WHOLE surface — the uninitialized
padding rows (NV12 Y=0,U=V=0, which converts to vivid green) landed at the
bottom of the output and the picture was squashed to fit. Set the source
rect to the real frame.
Pre-existing on this backend, but 40030e90 made D3D11VA auto's first choice
on Intel, so it went from a corner case to what every Intel user sees — a
~32 px green bar at 3840x2400, reported on glass within the hour.
Also dedupe the Settings GPU picker by description: that string IS the
identity downstream (persisted as Settings::adapter, matched by name as
PUNKTFUNK_VK_ADAPTER), so repeated enumerations of one adapter offered the
user the same choice twice — live on an Intel Arc laptop, whose Vulkan ICD
also enumerates the single physical iGPU twice. Both paths now log their
raw enumeration (decode texture dims; DXGI name/LUID/ids) for the next
report.

A PQ stream on the D3D11VA backend was always tone-mapped to sRGB by the
VideoProcessor — with D3D11VA now auto's first choice on Intel (40030e90),
Intel Windows users would have lost HDR entirely. When the presenter can
import an RGB10A2 D3D11 texture AND offers an HDR10 swapchain (the new
VulkanDecodeDevice::d3d11_hdr10 probe), the hand-off ring switches to
RGB10A2 and the VideoProcessor does a pure colorspace conversion (YCbCr
G2084 -> RGB G2084, no tone mapping); the emitted frame carries PQ/BT.2020
color, so the presenter flips its HDR10 swapchain and video image exactly
as it does for Vulkan Video PQ frames, and the blit passes the PQ values
through untouched. SDR-only paths keep the tonemap-to-sRGB BGRA8 ring;
in-band PQ flips rebuild the ring like a resize (generation-bumped).

Intel's Windows driver advertises Vulkan Video (Arc drivers since 2023), so
the capability gate alone no longer keeps Intel off FFmpeg-Vulkan — and that
combination is broken in the field (B580 report: strobing + 7.2 ms p50
decodes at 4K120) and on glass (Arc Pro iGPU: 29-33 ms p50 decodes at 4K60
where D3D11VA does 2.5 ms on the SAME GPU). Mirror the Linux vendor order on
Windows: NVIDIA/AMD keep Vulkan Video first, Intel/unknown take D3D11VA
first; vulkan stays reachable by explicit preference and as auto's fallback.
Also:
- Vulkan→D3D11VA mid-session demotion rung (the Windows analog of Linux's
Vulkan→VAAPI rung) — a failing Vulkan backend lands on hardware, not on
software, which cannot survive 4K120.
- The demotion streak now needs 1 s of age as well as 3 consecutive errors:
a startup loss burst produced 3 errors in 20 ms and stranded the session
on software decode (one-way) before the IDR requested on the first error
could possibly arrive — live-hit on the Intel iGPU leg.
- Stale "Intel's Windows driver has no Vulkan Video" comments corrected,
docs updated to the per-vendor order, vendor-order test extended with
discrete/iGPU Arc cases.
Verified on an Arc Pro iGPU + RTX 3500 Ada laptop against a CachyOS/NVENC
host: auto now picks d3d11va on Intel (60 fps, 2.5-2.8 ms decode, e2e 26 ms
vs 50 ms before) and still picks vulkan on NVIDIA. 27/27 pf-client-core
tests, clippy clean.

Field report (iPad Pro 13" M4, 2752x2064@120): display 23.1 ms on the default
arrival pacing vs 14 ms glass-gated, dominating an otherwise ~14 ms pipeline.
On iOS the layer ALWAYS vsync-latches (displaySyncEnabled is macOS-only API)
and default-on VRR steers the panel to the stream rate, so arrival pacing's
sticky-FIFO saturation (~2-3 refreshes of queue) is the common case, not the
corner — the exact regime that made tvOS default to glass.
- PresenterChoice.platformDefault -> stage3 on iOS/iPadOS (joins tvOS);
explicit stage-2 stays the honest arrival A/B; macOS unchanged.
- PresentGate generalized to a capacity: depth 1 is bit-identical to before;
iOS runs depth 2 (one flip scanning out + one queued for the next latch),
so a decoded frame presents immediately and latches the very next vsync
instead of serializing on the previous flip's on-glass callback — expected
~5-8 ms at 120 Hz. tvOS keeps depth 1 (proven; A/B first), macOS is pinned
to 1 (glass there is the DCP swapID-panic mitigation — serialization is
its point). PUNKTFUNK_GATE_DEPTH (1-3) is the on-device A/B lever.
- Settings picker derives its "(default)" marker from presenterDefault
instead of hardcoding stage-2 as default / stage-3 as experimental.

The Arch package build died in skia-bindings:
failed to run `ninja`, does it exist in PATH?: Os { code: 2, kind: NotFound }
pacman got cmake and nasm but never ninja, which skia-bindings' GN/Ninja
generator shells out to. The job only ever passed because a warm cargo cache
carried a prebuilt Skia, so it never reached the source build — one cache
eviction from breaking, which is exactly what happened on the v0.14.0 retag.

Every Linux package declared its maintainer as `noreply@anthropic.com` — the
git co-author trailer address, copied out of commit metadata into PACKAGE
metadata, where it is user-visible:
* deb: `Maintainer:` in the host/client/web/scripting control files, plus
the generated debian/changelog trailer (`dpkg -s punktfunk`)
* rpm: all three %changelog entries (`rpm -q --changelog`)
* arch: the PKGBUILD Maintainer comment
So installed packages named Anthropic as the maintainer of this project, and
pointed anyone with a packaging problem at an address that discards mail.
packages@unom.io is the project's real packaging identity — it's already the
EdDSA key (AF245C506F4E4763, "punktfunk packages") that sign-rpms.sh signs
every RPM with, and it's what packaging/rpm/README and the bootc Containerfile
document. The RPMs were therefore SIGNED by packages@unom.io while DECLARING
noreply@anthropic.com; those now agree.
Checked the other publisher surfaces — the Inno installer (AppPublisher=unom),
the flatpak metainfo (developer id io.unom) and the decky package.json were
already correct.

The GNOME 50 HDR format offer took the PQ transfer id straight from
pw::spa::sys, which only exists on libspa new enough to carry the
BT2020_10/SMPTE2084/ARIB_STD_B67 block. Ubuntu 24.04 (noble) — the .deb host
builder — ships older headers, so bindgen emitted no such constant and the
host failed to compile there:
error[E0425]: cannot find value `SPA_VIDEO_TRANSFER_SMPTE2084`
in crate `pw::spa::sys`
This never showed up locally or on the Linux CI: both run a current PipeWire,
where the binding is present. It broke deb.yml's build-publish-host job, so
v0.14.0 published its client .debs but no host .deb.
Spell the id out (14) instead. It's wire ABI, not a private detail — SPA
mirrors GStreamer's GstVideoTransferFunction and that block was added as a
unit, so the value is the same on every libspa that has the symbol. On one
that doesn't, PipeWire fails to intersect the offer and the session
negotiates SDR, which is what an HDR-incapable host should do anyway (the
path needs GNOME 50+ regardless).
A test pins our value against pw::spa::sys wherever the symbol exists, so a
renumbered enum fails loudly instead of silently mis-tagging the transfer
function. It only builds where tests are compiled — the .deb/.rpm builders
run plain `cargo build`, so it can't reintroduce the failure it guards.

`let mut hdr` tripped -D unused_mut on Windows: the only reassignment is the
GNOME colour-mode probe below it, which is #[cfg(target_os = "linux")]. Dropping
`mut` would break the Linux build, so allow unused_mut on non-Linux only — the
lint still fires on Linux if that probe is ever removed.
Second Windows-only breakage in this release that the Linux CI cannot see (see
also the ffmpeg_win swscale match): `cargo clippy --workspace` on the Linux
runner never compiles cfg(windows) code, and the Windows job builds only
punktfunk-host + punktfunk-tray.
Verified: cargo clippy --release -p punktfunk-host --features nvenc,amf-qsv,qsv
-- -D warnings on 192.168.1.173.

The GNOME 50 HDR work added PixelFormat::X2Rgb10 / X2Bgr10 but only taught the
Linux encoders about them. `sws_src` in the Windows-gated ffmpeg_win.rs matches
PixelFormat exhaustively, so the Windows host stopped compiling:
error[E0004]: non-exhaustive patterns: `X2Rgb10` and `X2Bgr10` not covered
--> crates\pf-encode\src\enc\windows\ffmpeg_win.rs:132:14
Linux CI never caught it — the file is cfg(windows), so `cargo clippy
--workspace` on the Linux runner never compiles it.
Both are Linux-only screencast formats (the Windows HDR path stays
Rgb10a2/P010, per the PixelFormat docs), so they join the existing bail arm.
Spelled out rather than folded into a `_` catch-all so the next PixelFormat
addition breaks this match again on purpose.
Verified: cargo check --workspace --all-targets --features nvenc,amf-qsv on the
Windows box (192.168.1.173).

MINOR, not patch: 31 commits since v0.13.0 carry 10 features, including a new
/api/v1/plugins surface with a regenerated OpenAPI spec + SDK client. Since
sdk-publish pushes this version to consumers, a patch bump would understate a
new API surface for anyone pinning ~0.13.
Headline work: GNOME 50 HDR screencast capture + Linux Main10 encode, PyroWave
4:4:4 + HDR end to end (Linux/Windows/Apple), the console-hosted plugin UI
surface, and the pyrowave perf work that lifted the 2.5 Gbps wall. Notable
fixes: the RSA host-identity keygen that broke every fresh Windows install on
0.13.0, and SDR negotiation on the Windows IDD-push path.
pf-clipboard / pf-inject / pf-vdisplay were still hardcoding 0.12.0 — the three
the 22b352c1 sweep missed. Switched to version.workspace = true so the next
bump stays one line. (fec-rs, pf-driver-proto and usbip-sim are deliberately
versioned independently and stay put.)

`cargo clippy --workspace --all-targets --locked -- -D warnings` was red on
main — three lints landed with the GNOME 50 HDR + PyroWave 4:4:4 work:
* pyrowave_wire.rs: `aw / 2 >> level` tripped clippy::precedence. Rust already
binds `/` tighter than `>>`, so this always parsed as `(aw / 2) >> level`
(subband dim at half res, then one halving per DWT level) — the parens are
purely explicit, no change in behaviour.
* linux/mod.rs: `probe_can_encode_10bit` sat after `mod hdr_tests`
(clippy::items_after_test_module) — moved above the test module, unchanged.
Lint-only; no functional change. fmt/clippy/test all green afterwards.

Every pairing surface in the Apple client still told users to open the web
console on port 3000 — the pre-move port. The console has served :47992 for a
long time, so anyone following the on-screen instructions hit a dead port and
had no way to approve the device or read the PIN.
Seven strings across ContentView, SessionModel and PairSheet (iOS/tvOS/macOS
share them). The two that spell out a full URL also said `http://`; the console
is HTTPS-only (host's self-signed cert), so they now read
`https://<host>:47992`, matching the phrasing in the host README, install docs
and the deb/rpm packaging notes.
Copy-only — no behavioural change; a repo-wide sweep found no other stale :3000.

`feat(hdr): GNOME 50 HDR screencast capture` (0e977817) landed with rustfmt

A Windows client with HDR off (video_caps=0) negotiates bit_depth=8, but the
H.26x IDD-push capture composition FOLLOWED the virtual display's live "Use
HDR" state rather than the negotiated depth. On a display whose advanced color
was on — leftover from a prior 10-bit session on a reused monitor, the driver
default, or the host's global toggle — the capturer emitted P010 and NVENC
stamped HEVC Main10 + BT.2020 PQ from the pixel format alone (the in-band HDR
upgrade). That 10-bit PQ stream reached a client that advertised SDR-only; on a
client whose monitor is HDR-capable but has "Use HDR" off, the PQ landed on an
SDR desktop and blew out.
Make client_10bit authoritative for the composition depth on BOTH codecs,
mirroring the PyroWave branch that already did this:
* setup: force advanced color OFF for any !client_10bit session (was
pyrowave-only), settling before the ring is sized;
* display_hdr gates on client_10bit alone, so an SDR-negotiated session
composes SDR even if a physical display forces HDR;
* the descriptor poller re-asserts SDR against a mid-session "Use HDR" flip for
any SDR-negotiated session (an HDR-negotiated H.26x session still follows
flips both ways — its encoder re-inits on the depth change).
Only Punktfunk's virtual display is touched, never the host's real desktop.
Not yet on-glass; the client-side robustness fix (presenter should tone-map PQ
on an SDR-mode display instead of taking an HDR10 swapchain) is a follow-up.

GNOME 50 (Mutter MR 4928, PipeWire >= 1.6) added HDR screen sharing for
monitor streams: 10-bit PQ formats (xRGB_210LE/xBGR_210LE) with MANDATORY
BT.2020 + SMPTE-2084 colorimetry props, advertised while the mirrored
monitor is in BT.2100 colour mode. Wire the Linux host into it end-to-end
on the GameStream desktop-mirror path (PUNKTFUNK_VIDEO_SOURCE=portal):
* pf-frame: PixelFormat::X2Rgb10/X2Bgr10 (DRM XR30/XB30; X2Bgr10 is the
Windows Rgb10a2 layout) + fourccs.
* pf-capture: want_hdr portal offer — HDR-only LINEAR-dmabuf pods with
MANDATORY PQ/BT.2020 props (SHM excluded: Mutter's SHM record path
paints 8-bit ARGB32 regardless of format; tiled excluded: the EGL
de-tile blit is 8-bit RGBA8), negotiated-colorimetry parse, generic
HDR10 hdr_meta(), packed-10-bit CPU cursor blend, a process-wide SDR
downgrade latch on negotiation timeout, and a DisplayConfig BT.2100
colour-mode probe (gnome_hdr_monitor_active).
* pf-encode: libav NVENC X2RGB10->P010 swscale (BT.2020 limited) ->
HEVC Main10 / 10-bit AV1 with PQ VUI; VAAPI 10-bit on both paths (CPU
P010 upload + dmabuf XR30 scale_vaapi p010/bt2020); can_encode_10bit
now probes for real on Linux; 10-bit sessions route around the
8-bit-only Vulkan-video/direct-NVENC backends.
* GameStream: host_hdr_capable() Linux arm, live monitor-HDR check at
RTSP honor time, capturer-pool reuse keyed on HDR-ness, gs_bit_depth
covers the new formats. New `punktfunk-host hdr-probe` diagnostic and
a PUNKTFUNK_SPIKE_HDR spike lever.
* Native plane stays honestly 8-bit via capturer_supports_hdr(): Mutter
RecordVirtual streams are SDR-only upstream (GNOME 50 and 51-dev), so
virtual-display sources cannot deliver HDR yet.
Validated on the RTX 5070 Ti (GNOME 50.3 / PipeWire 1.6.8): the Main10
probes pass and the ignored nvenc_hdr10_smoke GPU test emits an IDR that
ffprobe reads as Main 10 / yuv420p10le / bt2020nc / smpte2084 / limited.
Live HDR capture negotiation still needs an HDR monitor on glass; VAAPI
10-bit needs the AMD box.

`maximumExtendedDynamicRangeColorComponentValue` is the CURRENTLY-allocated EDR
headroom, which macOS hands out on demand — an idle SDR desktop reads 1.0 even
with an HDR display enabled and active, so gating HDR advertisement on it means
an HDR monitor (e.g. Samsung G95SC) never gets advertised at connect time. Use
`maximumPotentialExtendedDynamicRangeColorComponentValue`, the mode-independent
capability (the macOS analogue of the tvOS/iOS gates). Also point the Xcode
scheme's LaunchAction at Release.

The vendored rate controller packs its wavelet block index into 16 bits
(RDOperation.block_offset_saving), so a mode whose 32x32-block count exceeds
u16::MAX wraps inside the controller and corrupts the bitstream — ~8K-class
4:4:4 territory. Compute the exact count (`block_count_32x32`, the counting walk
of upstream init_block_meta, pinned against the validated Apple WaveletLayout)
and expose `pyrowave_mode_fits_rdo`; the negotiator downgrades such a session to
4:2:0 before the Welcome (the honest-downgrade channel), and both encoders
refuse outright if one slips through rather than emit a wrapped stream.
Vendor patches: 0002-rdo-saving-clamp (analyze_rate_control.comp clamps the
saving accumulation to the target, same overrun class as 0001; slangmosh.hpp
regenerated), 0003-devel-encode-16bit-read (devel tool y4m 16-bit plane reads;
tool-only, kept so the vendored source stays honest).

PyroWave's wavelet encode runs on the GPU's compute/shader cores, so a GPU-bound
game starves it: submit spikes from ~2 ms to ~15 ms under a 95%+ game load and
the stream fps collapses. NVENC is immune (separate encoder ASIC). Two levers to
let the encode get scheduled ahead of the game's rendering:
- Windows process GPU scheduling: D3DKMTSetProcessSchedulingPriorityClass, env
PUNKTFUNK_GPU_PRIORITY = off|above-normal|high (default)|realtime. Best-effort,
once per process, non-fatal on refusal (enc/windows/pyrowave.rs).
- Global-priority Vulkan encode queue (Granite patch 0005): request a
VK_KHR_global_priority queue (PYROWAVE_QUEUE_PRIORITY = off|high|realtime,
default realtime), downgrading REALTIME→HIGH→none on NOT_PERMITTED so a refused
class never regresses the encoder to HEVC.
HONEST STATUS: on an RTX 4090 / Windows / WDDM neither moved the ~15 ms spikes —
the graphics-vs-compute preemption granularity is the wall, not the priority
level. Kept because both are correct, harmless (graceful fallback), and may help
other GPUs/drivers. For a GPU-saturated game the working levers are reducing the
encode's GPU cost (4:2:0/8-bit) or H.265; PyroWave holds full rate on the desktop
and in games that leave the GPU headroom.

The frame-driven capture loop set its rate-limit floor (`earliest`) relative to
`next`, which is re-based to the instant AFTER submit(). For an async encoder
(NVENC) submit() returns in ~0, so that anchor is ~frame-arrival and the loop
correctly waits for the next vsync — full framerate. But PyroWave's encode is
SYNCHRONOUS (~2 ms inline in submit()), so the anchor lands ~2 ms late every
frame: the loop misses the next arrival and samples one interval behind, making
the period `interval + encode`. That capped a 240 Hz source at ~158 fps (and a
360 Hz request at ~200) with the link and the encoder both idle — no drops.
Anchor the floor to this frame's arrival (`t_cap`) instead. The synchronous
encode now overlaps the interval rather than stacking onto it; the ≥0.9×interval
spacing from the last grab still caps the rate at ~1.11× target. No-op for async
NVENC (t_cap ≈ post-submit there), which is why H.26x already held full rate.
Measured on-glass (5120x1440@240, RTX 4090 host, macOS client): desktop now
holds 240 fps. Also reduces latency (samples fresher frames).

A provider plugin that runs on the host (e.g. the Playnite sync plugin) can
now reconcile cover art as an on-host FILE PATH instead of an inlined data
URL. `GET /library` rewrites such local-file art into `/library/art/<id>/
<kind>` proxy URLs (the same relative-proxy shape Steam art already uses),
and the art proxy serves the bytes from the stored path. Moonlight's
/appasset proxy reads the local file too.
This is what lets a large Playnite library sync with covers: the reconcile
payload carries paths, not bytes, so it no longer blows past the mgmt API's
request-body limit and scales to thousands of titles.
Cross-platform; local-path detection is Windows-shaped (Playnite is
Windows-only). Unit-tested (compiles + 5/5 art tests on Linux).

- New "4:4:4 and HDR" section: what each mode buys, the ~1.6× / +15% bitrate
cost, that HDR needs a Windows host today (Linux capture has no HDR source),
and that the two combine (~1.9× the 4:2:0 SDR rate).
- Interactive <BitrateCalculator> (registered in the MDX components map):
resolution (presets or custom), frame rate, 4:2:0/4:4:4, SDR/HDR -> the
estimated Automatic pin, bits/pixel, per-frame size, and which link tier it
needs. Formula mirrors the host's resolve_bitrate_kbps_for exactly.
- Expanded the bandwidth table with 120 Hz rows; note the big modes want 5/10 GbE.
- Document PUNKTFUNK_PYROWAVE_MAX_MBPS (cap the open-loop pin on a constrained
link) in configuration.md.
- pyrowave.md -> .mdx so the page can host the component.

Real-world PyroWave streaming maxed ~2.5 Gbps with sagging fps while raw
transport does 4.8. Root-caused to serial per-frame paths at BOTH ends
(the transport was never the limit); this fixes the two dominant ones.
Host (vendored shim, patch 0004): pyrowave_encoder_encode_gpu_synchronous
allocated four Vulkan buffers (meta + bitstream, Device + CachedHost) on
EVERY frame. At 240 fps with MB-scale bitstreams that per-frame allocator
churn stalled the encode itself. Pool them on the encoder and reuse across
frames (recreate only on a size grow); the sizes are session-fixed, so it
is pure reuse after frame 1. On an RTX 4090 the 5120x1440 submit+fence-wait
drops ~15 ms -> ~1 ms, i.e. the host serial ceiling goes 64 -> 1025 fps
(444+HDR 44 -> 614). Safe under the synchronous encode model; re-validated
by pyrowave_win_smoke (Windows) and pyrowave_smoke/_444 (Linux). Applies to
both host encoder paths (they share the shim).
Client (Apple Metal decoder): WaveletBitstream.parse reserved the payload
buffer per packet (reserveCapacity(count + words), an exact realloc each of
~3000 packets/frame => O(n²)) and copied word-by-word. Reserve once up
front and memcpy each packet's coefficients in one shot (all Apple
platforms are little-endian, so the wire's LE u32s land verbatim; memcpy is
alignment-free). 5.44 ms -> 0.055 ms per 1.44 MB frame (25x); byte-identical
(parser unit tests + golden-frame PSNR unchanged).
Also:
- native.rs: PUNKTFUNK_PYROWAVE_MAX_MBPS caps PyroWave's open-loop Automatic
bitrate pin for hosts on a constrained link (unset => no cap; an explicit
client rate bypasses it). The pin is all-intra + ABR-off, so at a high
pixel rate it can outrun the fabric (4:4:4+HDR 5120x1440@240 pins ~5.3
Gbps, over a 5 GbE link) and the overshoot just becomes loss.
- pf-encode caps(): report the real opened chroma instead of a hardcoded
4:2:0 default, so a genuine 4:4:4 session no longer trips the spurious
"encoder chroma disagrees with the negotiated Welcome" warn. Also fix a
latent Windows reset() that rebuilt at 4:2:0 for a 4:4:4 session.

Dedicated single-game sessions now end cleanly when the launched game
quits, and Steam launches get gamescope's Steam integration without an
operator env knob.
End-on-exit: the existing APP_EXITED close only fired when gamescope's
PipeWire node vanished, which never happens for Steam — the nested
`steam` is the resident singleton client and stays up after a game
quits, so gamescope (and its node) never die and the stream sat on a
hidden Steam session forever. Add a Steam AppId reaper watcher
(pf-vdisplay .../gamescope/discovery.rs): steam_appid_from_launch()
parses steam://rungameid/<id>; wait_for_steam_game_exit() waits for the
game to start (<=300s grace) then exit (3s confirm); steam_game_running()
scans same-uid /proc for Steam's launch reaper matching both the
`SteamLaunch` and `AppId=<id>` argv tokens (exact-match; reaper lifetime
== game lifetime, so shader precompile can't false-trigger). The host
spawns a pf1-gamewatch thread for nested Steam launches that closes the
connection with APP_EXITED (launcher clients return to their library)
and sets quit/stop; cancelled via stop if the session ends first.
Non-Steam nested launches keep the node-death path (gamescope's child
IS the game).
Flags: auto-enable `--steam` whenever the launch is a Steam launch (was
only the global PUNKTFUNK_GAMESCOPE_STEAM knob, default-off) — in-game
overlay / Steam+X / gamepad-UI nav for Steam titles with no operator
config. New opt-in PUNKTFUNK_GAMESCOPE_GRAB_CURSOR adds
`--force-grab-cursor` for a real game launch (FPS mouselook); default
OFF because it forces relative mode, which breaks absolute-pointer
games/menus.
Verified: fmt clean; clippy -D warnings clean on the three crates;
pf-vdisplay 64/0 (incl. new steam-appid parse test); punktfunk-host
builds + 186/0; reaper /proc detection smoke-tested (detect, exact
non-match, gone-after-exit).

The main content wrapper used p-6 (24px) on mobile while the mobile top bar uses
px-4 (16px) — an inconsistent, oversized side gutter that ate into the usable
width on phones. Drop it to a 16px side gutter (px-4) on mobile, matching the top
bar; sm+ padding is unchanged. Also make the shared Card padding responsive
(p-4 on mobile → p-6 from sm up) so card content isn't double-inset on small
screens. Desktop layout is identical.

Phases 4+5 of design/pyrowave-444-hdr.md. The Metal decoder needs NO new ABI:
every frame's sequence header carries chroma (444) and, since the Phase-3
stamps, the PQ/BT.2020 bits — so the decoder self-configures per session.
Decoder: WaveletLayout grows the 4:4:4 block space (chroma runs the full
pyramid like luma — no level-0 skip, no early half-res emit; the Metal
kernels were already chroma-agnostic, only the dispatch structure changes);
the parser accepts chroma_resolution=444, reads the PQ transfer bit, and
lifts the even-dims rule for 444; the plane ring allocates full-res chroma
and r16Unorm for PQ streams; CSC rows switch to depth-10 MSB-packed.
Presenter: planar HDR passthrough reuses pf_frag_planar on an rgba16Float
drawable (itur_2100_PQ + EDR metadata interpret the samples — same split as
pf_frag/pf_frag_hdr), plus a new pf_frag_planar_tm PQ->SDR tone-map (shared
pqToSdr tail refactored out of pf_frag_hdr_tv) for tvOS-without-headroom AND
macOS WINDOWED sessions, whose IOSurface present path (the DCP-panic
mitigation) is BGRA8-only. SessionModel stops stripping the HDR/10-bit/444
caps on the PyroWave opt-in.
New golden: au-dense444 + upstream's own 4:4:4 reference planes (regenerated
via the extended pyrowave_dump_golden); Metal decode matches at 64-67 dB
(420 fixtures re-verify 77-88 dB). Full Apple suite 157 tests green on a
real M-series GPU. Docs updated: the 8-bit-SDR-only wording is gone, the
Windows host is no longer 'on the roadmap', bpp scaling documented.

Phase 3 of design/pyrowave-444-hdr.md. A PyroWave session now negotiates HDR
(10-bit) and 4:4:4 on a Windows host exactly like HEVC/AV1, and the Linux
client presents it through the real HDR10 path.
Host (Windows): BgraToYuvPlanes becomes mode-aware — SDR/BGRA and HDR/scRGB
variants at half- or full-res chroma. The HDR passes reuse HdrP010Converter's
exact colour math (scRGB -> PQ BT.2020 limited studio codes, verified by
hdr_p010_selftest) but write P010-style MSB-packed codes into two separate
shareable R16_UNORM/R16G16_UNORM textures; chroma keeps the pyrowave family's
centre-sited 2x2 box. idd_push pins the composition to the NEGOTIATED depth
(SDR sessions force advanced color off as before; 10-bit sessions enable it
and ride the FP16 ring), and the descriptor poller re-asserts that state
instead of following display flips the fixed-format encoder can't. The
encoder imports 8/16-bit planes per session and stamps the sequence header's
BT.2020/PQ/matrix bits on HDR (stamp_color_bits, extending 574e3e4e's range
stamp); supports_10bit/can_encode_10bit/can_encode_444 gates open (HDR
Windows-only — Linux capture has no HDR source).
Client: the plane ring becomes R16_UNORM for 10-bit sessions (with a
STORAGE_IMAGE format probe), the planar CSC pass joins the HDR10 swapchain
rebuild (set_hdr_mode previously destroyed it without rebuilding — latent),
st.hdr follows frame.color.is_pq(), and the planar push constants carry
depth-10 MSB-packed rows + the PQ tonemap mode, identical to the NV12 arm.
Verified: .173 (RTX 4090) deploy-config clippy + fmt + wire tests + the
extended pyrowave_win_smoke (10-case {SDR,HDR}x{420,444} matrix incl. R16
imports and header stamps); .21 (RTX 5070 Ti) clippy across 4 crates, host
186 tests, client/presenter/encode tests, both Linux GPU smokes.

Phase 2 of design/pyrowave-444-hdr.md. can_encode_444(PyroWave) now returns
true on Linux, so a client that advertises VIDEO_CAP_444 (the 4:4:4 setting)
and prefers PyroWave negotiates a full-chroma wavelet session end to end
(the client decoder side landed in 5eb930e7).
- rgb2yuv444.comp: the 4:4:4 twin of rgb2yuv.comp — one invocation per pixel,
full-res interleaved RG8 CbCr, no box filter/siting, byte-identical BT.709
limited coefficients; compiled .spv committed (glslangValidator -V, matches
the existing shader's toolchain).
- Encoder: chroma-conditional pyrowave create (open + reset), full-res chroma
plane + views, per-pixel dispatch, 4:2:0-only even-dims check.
- Tests: decode oracle grows a 4:4:4 mode (YUV444P CPU readback);
pyrowave_smoke_444 round-trips plane means AND drives the busy test card at
the ~2.6 bpp operating point asserting in-budget + run-to-run deterministic
AU sizes — the exact regime that silently corrupted before the vendored
payload_data fix (patches/0001), so this doubles as its regression test.
Verified on .21 (RTX 5070 Ti): clippy -D warnings, host tests, and both GPU
smokes (pyrowave_smoke + pyrowave_smoke_444) green.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Phase 1 of design/pyrowave-444-hdr.md. No behavior change yet: the handshake's
4:4:4 gate now admits PyroWave (probe = can_encode_444(codec), capture gate
inherently satisfied — the wavelet path always ingests an RGB source and does
its own CSC), but can_encode_444 stays false for PyroWave until the per-OS
full-res-chroma CSC variants land (Phase 2 Linux, Phase 3 Windows), so every
session still resolves 4:2:0/8-bit.
- Both host encoders take the negotiated ChromaFormat (bail on 444 for now);
the PUNKTFUNK_ENCODER=pyrowave lab override pins 4:2:0.
- Bitrate: the automatic ~1.6 bpp pin resolves AFTER depth+chroma and scales
x1.625 for 4:4:4 / x1.15 for 10-bit (factors from the Phase-0 fixture
matrix); the mid-stream mode-switch re-resolve threads the session's values.
- Client: PyroWaveDecoder builds its plane ring (full-res chroma when 444) and
creates the upstream decoder from the negotiated chroma, keeps chroma fixed
across mid-stream resizes, drops the even-dims requirement for 444, and
returns the negotiated Welcome ColorInfo as the frame colour contract
instead of hardcoded BT.709 (the wavelet bitstream has no VUI).
Verified on .21 (RTX 5070 Ti): clippy -D warnings (host+client+encode), host
186 tests, client + pf-encode tests, fmt, and the pyrowave_smoke GPU
round-trip through the patched vendored lib (97cf15e3).

Upstream sizes the raw quantized-payload worst-case buffer at
aligned_width*aligned_height*2 bytes: real headroom for 4:2:0's 1.5
samples/px, but half of what 4:4:4's 3 samples/px can produce. Busy 4:4:4
content overruns the buffer on the GPU and corrupts the adjacent meta/bucket
suballocations — nondeterministic corrupt bitstreams and encoder crashes at
ANY target bitrate (smooth content never trips it, which is why 4:2:0 and
simple 4:4:4 both look fine). Found by the Phase-0 measurement matrix for
design/pyrowave-444-hdr.md; fix validated alone via upstream's own devel
tools on the RTX 5070 Ti: deterministic byte-identical outputs across runs,
1080p + 4K, 8- and 16-bit, PSNR at the expected operating points.
Patch lives in crates/pyrowave-sys/patches/ and vendor-pyrowave.sh now
re-applies patches on re-vendor; PUNKTFUNK-VENDOR.txt records it. Upstream
report to follow. No wire/ABI change; 4:2:0 sizing unchanged.

The runner only found unscoped `punktfunk-plugin-*` packages. An unscoped
package can't be split across registries, which forced plugins to bundle their
own copy of @punktfunk/host + effect (the plugin's Gitea registry has no
`effect`; `--registry <gitea>` 404s it). Discovering the scoped
`@punktfunk/plugin-*` convention lets a plugin resolve cleanly from one scope
map and depend on @punktfunk/host + effect as SHARED (hoisted) deps instead of
bundling — no per-plugin duplication. Additive: unscoped names still work.
Bumps @punktfunk/host to 0.1.1.

The DCP "mismatched swapID's" kernel panic reproduced on a 240 Hz Mac
Studio with stage-3 glass pacing active: a fully serialized,
one-in-flight present stream still races WindowServer's own swap
submissions. So the mitigation has to change the MECHANISM, not the
rate — the CAMetalLayer image queue itself is the racing path in a
composited (windowed) session.
Windowed PyroWave now presents the way video players do: the planar
CSC renders into a pooled IOSurface (4 × BGRA8, in-use-aware LRU
reuse) and the render thread hands it to a plain CALayer's `contents`
on main inside an ordinary CATransaction. WindowServer treats that as
normal layer damage on its own composite cadence — no out-of-band
image-queue swaps to race. Fullscreen keeps the CAMetalLayer path
(direct scanout, no compositing, no panic reports); the hosting view
pushes the window's composited state on every layout, and flipping
modes just covers/uncovers the metal layer (no black flash).
VT codecs keep the metal path everywhere: no panic reports there, and
their HDR/EDR presentation has no surface-contents equivalent wired.

pyrowave's encoder fills the BitstreamSequenceHeader with `= {}` and its C API
offers no way to set colour/range, so it signals ycbcr_range=0=FULL — but both
host CSCs (rgb2yuv.comp on Linux, BgraToYuvPlanes on Windows) always emit BT.709
LIMITED Y'CbCr (black = Y'16). A client that honours the VUI (the Apple wavelet
decoder reads bit 30 of word1) then skips the limited→full expansion and shows
washed-out, raised blacks — reported on both Linux and Windows hosts.
Patch the range bit HONEST (mark_limited_range in the shared pyrowave_wire, called
by both encoders after packetize). Clients that hardcode limited (the Vulkan
video_pyrowave path) are unaffected, and pyrowave's own decode ignores the flag
(raw Y'CbCr reconstruction). No client rebuild needed. Unit-tested + asserted in
pyrowave_win_smoke; the smoke decode still round-trips 100/180/60.

Wire PyroWave into the Windows host (design/pyrowave-windows-host-zerocopy.md).
Before this a macOS client + Windows host that both selected PyroWave silently ran
HEVC: the host never advertised CODEC_PYROWAVE and open_video_backend bailed.
Approach (zero-copy, no GPU→CPU→GPU): pyrowave owns its own Vulkan device
(create_device_by_compat, by render-GPU vendor/device-id — NOT LUID, invalid in
Session 0). The capturer runs a BGRA→YUV BT.709-limited CSC (matching rgb2yuv.comp)
into TWO SEPARATE shareable plane textures — full-res R8 Y + half-res R8G8 CbCr —
which the encoder imports into pyrowave's device. Separate single/two-component
textures import reliably on NVIDIA at any size; a single planar NV12 import does NOT
(the vendored interop test: "only very specific resource sizes" — confirmed on-glass:
1024² fine, 720p/1080p/1440p garbage). A shared D3D11 fence, signalled after the CSC,
is imported as a Vulkan timeline semaphore so the wavelet read is ordered after it.
- pf-encode: enc/windows/pyrowave.rs (Encoder impl, two-plane import + Linux-style
plane views); host_wire_caps advertises CODEC_PYROWAVE on Windows when the backend
isn't Software; open_video_backend routes a negotiated PyroWave session first;
pyrowave-sys on the Windows target; interop confirmed at open → clean HEVC fallback.
- pf-encode: shared, unit-tested enc/pyrowave_wire.rs (single source of truth for the
client-facing AU framing); Linux encoder uses it too.
- pf-capture: dxgi.rs BgraToYuvPlanes CSC; idd_push.rs pyrowave mode — forces the
virtual display SDR (the VideoProcessor can't ingest the FP16 HDR ring), a
two-plane shareable out-ring, a shared fence passed every frame (so a rebuilt
encoder re-imports it). Threaded via OutputFormat::pyrowave.
- pf-frame: D3d11Frame::pyro carries the CbCr plane + fence; OutputFormat::pyrowave.
Verified on .173 (RTX 4090): full-host build + clippy -D warnings (nvenc,amf-qsv) +
fmt --all --check; pyrowave_wire unit tests; pyrowave_win_smoke GPU test round-trips
distinct Y/Cb/Cr (100/180/60) exactly at 1024²/720p/1080p/1440p; Stage-0 interop
validated in the real Session-0 service context on-glass. Deployed to the box.
Owed: final on-glass picture/latency confirmation.

The host .deb was built on the Ubuntu 26.04 rust-ci image, so dpkg-shlibdeps
baked in `Depends: libavcodec62` (FFmpeg 8) and a glibc-2.41 floor — making it
uninstallable on Ubuntu 24.04 LTS (FFmpeg 6.1 / libavcodec60, glibc 2.39; apt
reports the deps as "too recent"). The source floor (ffmpeg-next 8, libavcodec
>=61 APIs) means a straight 24.04 rebuild would fail too.
Build the host on Ubuntu 24.04 instead — lowering the glibc floor to 2.39 so one
binary runs on 24.04 -> 26.04 — and bundle a from-source LGPL FFmpeg 8 into the
package so it no longer depends on the distro libav*. Everything else the host
links is soname-compatible on 24.04 (opus is vendored via cmake; NVENC/libcuda
are dlopen-only, never link-time), and the only FFmpeg encoders used are
*_nvenc / *_vaapi (software H.264 fallback is the BSD-2 openh264 crate, not
FFmpeg libx264), so an LGPL build keeps the bundle license-clean.
- ci/rust-ci-noble.Dockerfile (new): ubuntu:24.04 builder; nv-codec-headers +
FFmpeg 8 (--enable-nvenc --enable-vaapi, shared) -> /opt/ffmpeg; PKG_CONFIG_PATH.
- packaging/debian/build-deb.sh: BUNDLE_FFMPEG=1 copies libav*/libsw*/libpostproc
into /usr/lib/punktfunk-host, patchelf-sets the rpath ($ORIGIN per-lib + binary
--force-rpath), feeds them to dpkg-shlibdeps (captures libva2/libdrm2), and drops
the libav* sonames from Depends. Normal (non-bundle) path unchanged.
- .gitea/workflows/deb.yml: split into build-publish (client/web/scripting on the
26.04 image) and build-publish-host (noble image, BUNDLE_FFMPEG=1); parallel,
identical version step, same apt distribution -> one universal host .deb.
- .gitea/workflows/docker.yml: build+push punktfunk-rust-ci-noble.
- packaging/debian/README.md: document the 24.04 LTS path + bundled local build.

Windowed PyroWave sessions were kernel-panicking Macs ("mismatched
swapID's" @UnifiedPipeline.cpp, WindowServer → AppleMobileDisp*-DCP).
The panic is an Apple DCP bug (SketchUp/Unity/240Hz-monitor reports hit
the same signature), but our stage-2 arrival pacing feeds the trigger
pattern: displaySyncEnabled=false out-of-band presents arriving faster
than the compositor latches them in a composited (windowed) session.
PyroWave makes that pattern routine — near-instant Metal wavelet decode
turns network clumps into same-millisecond present bursts, and it is
the codec that sustains stream rates above panel refresh.
Mitigation: PyroWave sessions on macOS now default to the stage-3
PresentGate (one presented-but-undisplayed swap in flight, serialized
on the on-glass callback, 100 ms stale backstop) — the racing pattern
cannot occur. Explicit stage2/stage3 picks (setting or
PUNKTFUNK_PRESENTER) still win, so the arrival-pacing A/B stays honest.
VideoToolbox codecs keep arrival pacing (decode latency spaces their
presents; no panic reports there).
PresenterChoice gains an `explicit` resolver (nil = no user selection)
so the codec-conditional default only applies when the user hasn't
picked a stage; pacing selection is a testable helper carrying the
rationale.

The "Which should I use?" table on the clients page listed most client
names as bold text, not links — only the Decky plugin and pf-webos were
clickable — so the client references appeared broken. Link each client to
its section (or dedicated page), and fix a stale Windows headless command.
Repo-wide docs correctness/staleness pass against the code:
- steam-deck: client-not-found -> flatpak-not-found (the real backend code)

- roadmap: clipboard sync is shipped, not planned
- install-client: MSIX/cert artifacts are arch-suffixed (_x64/_arm64)
- requirements: fix garbled 22H2/IddCx sentence
- status: Linux encode also covers AMD/Intel (VAAPI/Vulkan Video)
- automation: add the plugins.changed event

The clippy step ran in the default (debug) profile, compiling the whole
dep tree into a second target dir (C:\t\debug) — a second full build of
openh264-sys2's vendored C++ (pf-encode's software-H.264 fallback) on top
of the release copy the Build steps already produced. That second cc-rs
cl.exe fan-out tips the self-hosted runner into
`cabac_decoder.cpp: fatal error C1069 (cannot read compiler command line)`
— environmental disk/temp exhaustion, not a source error: the identical
file compiles fine in the release build minutes earlier, and openh264 is
untouched here. Linting in --release reuses the release build-script
artifacts (no openh264 rebuild) and keeps everything in one C:\t\release
tree. Matches pf-vkhdr-layer's clippy, which already runs --release.

The workspace went ring-only in 0.13.0 (aws-lc-sys breaks Windows CI), and
`ring` can sign with an existing RSA key but cannot *generate* one —
rcgen's ring backend returns `KeyGenerationUnavailable` for
`generate_for(&PKCS_RSA_SHA256)`. So `ServerIdentity::{load_or_create,
ephemeral}` panics with "rcgen RSA keygen / There is no support for
generating keys for the given algorithm" on any host without an existing
`cert.pem`. This is the shared trust root for both the GameStream TLS cert
and the QUIC identity clients pin, so a *fresh* 0.13.0 install can't start
the host at all (existing dev boxes survive only because they already have
a cert on disk); in CI every test that builds a `ServerIdentity` (all of
`mgmt::tests`, `gamestream::nvhttp`, and the `native::tests` synthetic host
via `serve()`) failed — 30 failures from this one cause.
Moonlight requires an RSA-2048 identity, so generate the key with the
pure-Rust `rsa` crate (already a dependency for the pairing signer) and
hand its PKCS#8 PEM to rcgen, whose ring backend *can* load and self-sign
with an externally supplied RSA key (`from_pkcs8_pem_and_sign_algo` →
`RsaKeyPair::from_pkcs8`). Return that same PEM so it stays byte-identical
to what `from_pems` re-parses.

`is_transient_io` only recognized `ENOBUFS` on unix; on Windows the
`#[cfg(not(unix))]` arm returned `false`, so `WSAENOBUFS` (10055) — which
Rust maps to `ErrorKind::Uncategorized`, missing the `WouldBlock` arm —
propagated out of the USO `send_gso` path through `Session::send_sealed`
and killed the session with `native::stream` "send failed — stopping
stream". A high-bitrate keyframe burst (one `WSASendMsg` USO super-buffer
is up to ~512 segments) momentarily exhausts the socket send buffer / AFD
non-paged pool; it's a lossy drop that FEC + the next frame recover,
exactly like the unix `ath11k` `ENOBUFS` case the classifier already
handles. Fires independently of client platform (Windows/macOS clients
both saw the crash) because it's the Windows *host's* send socket.
Add a `#[cfg(windows)]` arm matching `WSAENOBUFS` plus the
`WSAENET*`/`WSAEHOST*` network-path family (the Windows counterparts of
the droppable unix set), and extend the classifier test with per-platform
raw-errno coverage so the Windows CI runner exercises the 10055 path.

docs/automation.md promises 'changes apply immediately, no restart' for BOTH
config paths, but the store loaded hooks.json once (OnceLock) — only PUT
/api/v1/hooks applied live, and a hand-edited file silently did nothing until
the next host start. Since the file is the accessible path most users will
take, make it real: get() re-stats the file per event (mtime + length) and
re-reads it on change, with the same lenient contract as startup (missing =
no hooks, invalid = disabled loudly). set() records the identity it wrote so
the API path doesn't trigger a spurious reload.
Validated live on the 0.13.0 host (.21): full connect/disconnect lifecycle
fires exec hooks (client.*/session.*/stream.*) — the reload gap was found
setting that test up.

Companion to the host ring fix: pf-client-core declared rustls with
features=["ring"] but WITHOUT default-features=false, so rustls's default
aws-lc-rs backend came along too (feature tree: aws-lc-rs <- rustls default <-
pf-client-core default) — pulling aws-lc-sys 0.41.0 into the Windows client +
session + presenter builds, the same C dep that fails on the CI runner. Pin
default-features=false + [ring, logging, std, tls12] (matching the tray/host/core
pattern). aws-lc-sys now gone from EVERY windows-built crate (host, client-windows,
client-session, tray — all 'cargo tree -i aws-lc-sys' => no match). Code already
used rustls::crypto::ring::default_provider (library.rs); no behaviour change.
Validated: cargo tree (all 4 windows crates aws-lc-free) + .21 clippy -D warnings
(pf-client-core, pf-presenter, punktfunk-client-session) clean.
The Windows host clippy CI broke building aws-lc-sys 0.41.0 (a heavy C dep that
cl.exe fails to compile on the runner). The host was the ONLY thing pulling it:
its rcgen used features=["aws_lc_rs"], and bare `rustls`/`tokio-rustls` take
the default (aws-lc-rs) backend, and gamestream/{mod,tls}.rs installed the
aws_lc_rs crypto provider explicitly — a pre-existing deviation from the
project's documented ring-only design (punktfunk-core + the client are ring).
Align the host to ring: rcgen/rustls/tokio-rustls pinned to the `ring` feature
(keeping tls12 for Moonlight/GameStream TLS-1.2 clients) and the two GameStream
provider installs switched to `rustls::crypto::ring::default_provider()`. Both
providers offer the same standard TLS 1.2/1.3 suites, so it's transparent to the
TLS paths; aws-lc-sys/aws-lc-rs leave the tree entirely (`cargo tree -i
aws-lc-sys` => no match). Not caused by the preceding log fix (that touched no
crypto deps / the lock).
Validated: cargo tree (aws-lc-sys gone, windows target, amf-qsv,qsv features) +
.21 host clippy -D warnings (--features nvenc) clean. Owed: GameStream on-glass
re-check with a real Moonlight client (low risk — same TLS suites, client is
already ring).
The W7/W8 client refactor (extracting FullscreenController/ApprovalRequest out of
ContentView, splitting Settings) landed the DefaultsKeys + scaffolding but dropped
the feature WIRING, which was uncommitted WIP shelved in a stash during the
16:28 clipboard/v4 reconcile. Recovered from that stash (+ its untracked-files
parent for the whole new ModifierLayout.swift) and re-ported onto the refactored
tree:
- invertScroll: applied in InputCapture.sendScroll (the one scroll sink) + Settings toggle
- modifierLayout (Cmd/Option switch): restored ModifierLayout.swift enum + KeyMaps
.applyModifierLayout + InputCapture.emitKey wire-boundary + Settings picker
- fullscreen shortcut (Ctrl+Cmd+F): InputCapture ⌃⌘F interception + onToggleFullscreen
+ StreamView wiring + Stream-menu item (the .punktfunkToggleFullscreen sink +
FullscreenController observer already survived on main)
- render scale: Settings picker + MatchWindowFollower renderScale/maxDimension
application + StreamView/StreamViewIOS plumbing (RenderScale.swift already on main)
StreamCommands re-ported by hand (the stash hunk deleted the since-landed clipboard
item — kept it, added the fullscreen item alongside). Recovered ModifierLayout +
RenderScale tests. swift build green; 15 tests pass.

The `wasapi` audio crate polls the default output device ~1×/s and
`log::debug!`s it (`wasapi::api default device Ok(...)`), flooding host.log
even at RUST_LOG=info: those `log`-crate records reach tracing through the
tracing-log bridge, and at *filter* time they carry the bridge's "log" shim
target, so neither a bare-info EnvFilter nor a `wasapi=warn` directive on the
file layer matches them (the ring already drops them post-hoc via
normalized_metadata + NOISY_DEBUG_TARGETS — the fmt layer filters pre-event and
can't).
Fix at the source: a shared `log_capture::install_global` replaces
SubscriberInitExt::init in both init paths (service file log + interactive
stderr) and inits the tracing-log bridge with `ignore_crate("wasapi")`, so the
poll records are dropped before they ever become tracing events — both sinks go
quiet, while every other log-crate dependency still reaches the console ring
(bridge max-level stays DEBUG). `wasapi` also added to NOISY_DEBUG_TARGETS as
belt-and-suspenders, and `log` moved dev-dep -> dep for LevelFilter.
Validated: .21 clippy (host --features nvenc) clean.

Ship the management web console and the plugin/script runner across the packaging
matrix, and fix a Linux tray startup crash.
- nix: add punktfunk-web (Nitro SSR on bun) and punktfunk-scripting (Effect runner),
with services.punktfunk.{web,scripting} modules. Both bun node_modules come from
fixed-output derivations pinned to real deps hashes; patchShebangs the web
node_modules so orval/paraglide/vite run in the sandbox. Validated on x86_64-linux
(nix build .#punktfunk-{web,scripting,tray,host} all green).
- punktfunk-scripting now ships for deb/rpm/arch/nix/windows, mirroring the web-console
mechanics (vendored bun on deb/rpm/arch, pkgs.bun on nix; one self-contained
`bun build --target=bun` bundle). Opt-in: host Recommends it, but the systemd --user
unit ships un-started (Windows registers its scheduled task disabled).
- fix(tray): build punktfunk-tray in its OWN cargo invocation on nix/rpm/arch. Cargo
unifies features across one `cargo build`, so co-building the tray with the host pulls
the host's ashpd->zbus/tokio onto the tray's shared zbus and it panics at startup
("there is no reactor running, must be called from the context of a Tokio 1.x
runtime"). Isolated, the tray's zbus stays on async-io. The .deb already did this;
runtime-verified on nix.

The iOS/tvOS/macOS-AppStore archive steps sign development-automatic OFFLINE
(no -allowProvisioningUpdates), so they depend on Xcode's cached managed dev
profiles. Adding the App Groups capability (group.io.unom.punktfunk, shared with
the Widget/Live-Activity extension) invalidated the cached "iOS Team Provisioning
Profile: io.unom.punktfunk" (it carries no application-groups entitlement) and
there is no managed dev profile for the embedded io.unom.punktfunk.widgets at all
— so the archive fails with "doesn't include the App Groups capability" and
"No profiles for io.unom.punktfunk.widgets".
Add -allowProvisioningUpdates + the ASC auth key (asc.p8 already written to
RUNNER_TEMP) to all three archive commands so Xcode syncs the App ID capabilities
and regenerates/creates the managed *development* profiles. This is development
signing against the Apple Development cert already in the keychain — no cert
creation, so the App-Manager ASC key suffices; the manual distribution export
steps are untouched.
Also drop the widgets IPHONEOS_DEPLOYMENT_TARGET from 27.0 (an iOS-27-beta-era
value, out of range on the runner's iPhoneOS26.5 SDK) to 17.0, matching the app.

From the 2026-07-17 on-glass finding (.173 RTX 4090): the IDD-push capturer's
depth-2 pipeline measured ~13ms of glass-to-glass latency over depth-1 at
60fps (17ms → 4ms) — the AU is ready in µs but depth-2 holds it a whole frame
interval unpolled while N+1 is submitted. Depth-2 only earns its keep under
GPU contention (it overlaps the convert of N+1 with the encode of N, avoiding
the depth-1 ~50fps collapse). So the native encode loop now runs depth-1 by
default and escalates to the capturer's max ONLY when it can't hold cadence at
depth-1 (a leaky-bucket over 'the frame's work overran its pacing deadline',
with a startup warmup skip), then holds there for the session (no oscillation;
de-escalation is a v2 item). PUNKTFUNK_IDD_ADAPTIVE=0 pins the capturer's full
depth (pre-adaptive behaviour); no effect where the capturer's max is already
1 (every non-IDD backend). GameStream plane untouched.
Pairs with the shipped REALTIME auto-gate (1bc156aa): uncontended sessions get
the ~13ms latency cut, genuinely GPU-bound ones keep the depth-2 overlap AND
the REALTIME priority. Validated: .21 clippy -D warnings (host --features nvenc).

design/latency-reduction-2026-07.md T2.5's Linux half: the LINEAR dmabuf path
(gamescope's only offer) fed NVENC RGB, paying its internal RGB->YUV CSC on
the SM the game is saturating — the exact contention §5.A removed everywhere
else. The Vulkan bridge now carries a buffer-to-buffer RGB->NV12 compute
shader (rgb2nv12_buf.comp, BT.709 limited, coefficient-identical to
pf-encode's rgb2yuv.comp; whole-word writes so no 8-bit-storage feature is
needed): import dmabuf -> dispatch CSC into the exportable buffer -> CUDA
de-strides both planes into a pooled two-plane NV12 buffer. PUNKTFUNK_NV12
(default-on) now covers LINEAR; a CSC failure latches RGB for the stream
(mid-frame fallback, no dropped frame); 4:4:4 LINEAR sessions stay RGB (never
silently subsample). New ImportKind::LinearNv12 rides the existing worker IPC
(appended last per the wire-tag rule); cursor stays downstream (blend_nv12).
Validated: .21 clippy -D warnings (pf-zerocopy/pf-capture/host+nvenc) + 17

Surfaced by giving windows-host CI its missing pf-encode/pf-frame path triggers:
the T2.3 auto-gate (dxgi.rs) and the clipboard host (windows.rs) landed with
Windows clippy owed — three undocumented unsafe blocks, one manual checked
division, one comment orphaned off its statement, and a latent E0432 in
standalone pf-clipboard builds (WNDCLASSW needs Win32_Graphics_Gdi; the host

DLLs — ffmpeg *_qsv stays as the fallback until Phase 4). Adds pf-encode/** +
libvpl-sys/** to the paths trigger (drift from the W6 split: encoder changes
only reached this workflow via Cargo.lock luck). Exports
CMAKE_POLICY_VERSION_MINIMUM=3.5: audiopus_sys' vendored opus fails a FRESH

runs were one cache purge from breaking.

design/latency-reduction-2026-07.md tier 2, the two code-side halves:
- T2.2: the Linux direct-NVENC backend gains the two-thread retrieve
(PUNKTFUNK_NVENC_ASYNC, the same opt-in knob as Windows): the session stays
sync-mode (async events are Windows-only) but the blocking lock_bitstream
moves to a dedicated pf-nvenc-out thread — the NVENC guide's sanctioned
submit-thread/output-thread split. poll() drains completions non-blocking,
submit() backpressures at PUNKTFUNK_NVENC_ASYNC_DEPTH (default 4) in-flight;
map/unmap and every other session call stay on the encode thread; teardown
joins the thread before destroying the session. Under a GPU-saturating game
completed frames queue instead of serializing capture on the encode wait.
- T2.3: PUNKTFUNK_GPU_PRIORITY_CLASS gains 'auto' AND IT IS THE NEW DEFAULT
(gpu-contention §5.C): HIGH immediately, then REALTIME where the documented
NVIDIA+HAGS+near-full-VRAM NVENC hang cannot bite — HAGS probed once via
D3DKMT WDDM_2_7_CAPS (off => REALTIME outright); HAGS on => a pf-gpu-prio
monitor flips REALTIME<->HIGH on LOCAL-segment VRAM headroom (downgrade
>92% of budget, restore <=85% for 3x2s polls). 'high' restores the old
static default; 'realtime' pins it (operator owns the hazard).

Transcoding every image to PNG was the Phase-1 floor, but it bloats lossy
originals (a copied JPEG re-encoded lossless is 5-10x the bytes for zero
quality gain — feeding the render-timeout on constrained links) and flattens
GIFs to one frame. The wire already carries kind LISTS, so offer the original
format beside the portable fallback and let the destination pick:
- New wire kinds image/jpeg + image/gif (§3.5 extension; strings only, no
protocol change). image/png stays the universal floor every peer accepts.
- macOS: public.jpeg / com.compuserve.gif rows pass through verbatim both
directions; the PNG floor is announced whenever any image is present.
- Windows: registered JFIF/GIF formats read + promised verbatim; every image
offer still promises CF_DIB, whose delayed render now fetches the richest
offered kind (png > jpeg > gif) through the generalized image_to_dib.
- Linux maps gain the matching rows (native MIME pass-through).

design/latency-reduction-2026-07.md tier 1, remaining halves:
- T1.1: the native encode loop wakes on the capture's ACTUAL arrival instead of
sampling at a free-running tick — deletes the sample-and-hold (~half a frame
interval on average, a full one worst-case: ~8ms avg @60fps). New
Capturer::supports_arrival_wait/wait_arrival pair (IDD-push waits its
frame-ready event against the shared-header token; the PipeWire portal blocks
its channel with a pending stash); backends without an arrival signal — and
PUNKTFUNK_FRAME_DRIVEN=0 — keep the legacy tick bit-identically. A
0.9x-interval rate floor caps encode at ~1.11x target when the compositor
outruns the session; a +0.5x-interval keepalive keeps static desktops
re-encoding at 1.5x-interval cadence. Pacing deadlines re-anchor to the
actual submit so they can't drift against the arrival clock. GameStream
plane untouched.
- T1.4: the jump-to-live detectors run on WALL-CLOCK now (STANDING_TIME /
FLUSH_AFTER = 250ms) instead of 30-frame counts whose meaning scaled with
fps (500ms @60 but 125ms @240 — and stretching further under T1.1's slower
static-scene repeats). The queue trip also requires depth still >= high, so
a hysteresis-band hover can't fire on elapsed time alone.
Validated: .21 Linux 185 core + 177 host + pf-capture tests, clippy
-D warnings; .133 Windows cargo check of pf-capture + punktfunk-host green.

design/latency-reduction-2026-07.md T0.1/T0.2/T1.2/T1.3:
- T1.2 rate-capped front-loaded pacing: the paced overflow's budget is now
min(0.9x slack, overflow wire time at ~3x the live encoder bitrate)
(PUNKTFUNK_PACE_FACTOR, 0 = legacy deadline-only spread). A 300 KB-1 MB
frame's tail leaves in ~2-5 ms instead of smearing across ~15 ms at 60 fps;
GameStream schedule byte-identical (pins unchanged).
- T1.3 data-first wire order: packetize emits every block's data shards before
any parity (per-block parity pools keep all blocks' parity alive for the
second pass), so lossless completion stops waiting behind the parity tail.
EOF = last emitted packet; receiver already order-agnostic.
- T0.1 staged 0xCF: HostTiming gains an append-extensible per-stage tail
(queue/encode/pace us; seal+channel-wait derived as residual) - no cap bit
needed, old peers read the 13-byte prefix. Joined client-side into
Stats::host_{queue,encode,xfer,pace}_ms, the OSD detailed tier, and the
probe's report.
- T0.2 true on-glass present timing: VK_KHR_present_id/present_wait enabled
when supported; a PresentTimer waiter thread resolves each present id to
real visibility, replacing the submit-time display stamp (which undercounts
by up to a refresh and hides a silent-FIFO standing queue).
Validated on .21: core 185 + host 185 tests, pf-presenter 19, clippy
-D warnings across all five touched crates; loss-harness recovery curve
unchanged; C ABI harness round-trips.

Client-side supersampling/downscaling: the client asks the host to render
and encode at chosen-resolution × scale (the host does no scaling) and the
presenter rescales the decoded frame to the display. >1 supersamples for
sharpness; <1 lightens the host GPU and the link. Default 1.0 = Native, the
prior behavior.
The geometry lives once in punktfunk_core::render_scale (multiply, preserve
aspect ratio, floor to even, clamp to the codec's per-axis ceiling — 4096
for H.264, 8192 otherwise), the Rust twin of the Apple client's
RenderScale.swift, consumed by the native session client, the presenter's
match-window path, the Windows/Linux settings UIs, Decky, and Android
(settings + host connect + unit test).
Implemented and platform-verified by the Apple-client-features session
(Linux+Android+Apple green there); the punktfunk-core wiring
(pub mod render_scale) is restored here after being lost in a working-tree
reconciliation.

The low/medium findings from the July host+Windows security review, as
implemented in the audit session's working tree:
- Webhooks and library-art fetches refuse loopback/link-local/metadata
targets and no longer follow redirects (SSRF pivots from the privileged
host process).
- The paired-client rosters (/clients, /native/clients) move off the
streaming-client auth lane — one paired device could enumerate every other
device's name + fingerprint; only the bearer/loopback console keeps them.
- Device-name sanitizing extends to bidi/format control characters
(spoofable rendering) via the shared native_pairing::is_spoofy_char;
stream-marker quoting uses the same set.
- The SYSTEM service resolves powershell by its full System32 path —
CreateProcess checks the launching EXE's own directory first, so a planted
powershell.exe beside the host binary would have run as SYSTEM.
- The pf-vdisplay driver's opt-in file log moves from world-writable
C:\Users\Public to WUDFHost's own temp dir.
- GameStream pairing sessions are single-use (removed whatever the outcome).
- Uninstall also removes the pf_mouse driver-store entry (rider from the
virtual-HID-mouse work).
- openapi.json regenerated (hardened-config-dir doc wording).

Root cause of the field report (Android client, Windows host: no audio until
the user manually cycled Sound-output devices, then audio on BOTH PC and
phone): the WASAPI loopback captured whatever the default render endpoint
was at open time — not the wiring plan's chosen endpoint — the plan's
IPolicyConfig default-set is warn-only and racy, and nothing reacted to
mid-stream default-device changes.
- Explicit-endpoint capture: the capture thread opens the plan's
loopback_render by id, never "the default" (KEEP_DEFAULT preserves the old
default-capturing behavior with the echo guard).
- Client-only playback default: wiring_plan::plan(..., host_audio) prefers a
silent sink (Steam Streaming Microphone render side — loopback-validated,
silent on host) over real hardware, so stream audio plays on the client
only; PUNKTFUNK_HOST_AUDIO=1 restores real-hw-first (audible on the host).
The capture side auto-installs the Steam pair once per process when no
silent sink exists; open() handshake timeout 3s -> 30s to cover it, and a
handshake timeout now stops the detached thread (it used to run for the
process lifetime with the default still parked).
- Self-healing capture thread (wasapi_cap): outer capture_once loop
(Assert|Follow) with a ~1s watchdog on the default render id. A user
switch to a capturable endpoint is followed (their choice wins, audio on
both); a switch to a dud (cable/SSS/mic target) re-asserts the plan;
IPolicyConfig-denied converges to Follow instead of churning. Device
errors reopen with 2s backoff; only the FIRST open failure is fatal.
Zero-packets breadcrumb after 30s distinguishes broken-loopback from
quiet-desktop.
- Park/restore of the default playback device (audio_control):
wire_now(set_playback) parks the default on the loopback sink only for the
capture's lifetime (the mic pump passes false — it runs while the host is
idle); crash marker audio-default.prev + recover_orphaned_default() at
first wire; restore is skipped if the operator changed the default
themselves. A mic-default hygiene pass keeps VB-Cable installs audible and
never records the mic target as the restore target.
- Session-end park_audio_capture(): Windows DROPS the capturer (thread join
restores the default) instead of caching it; Linux keeps the parked
PipeWire thread. Composes with the stream-sink idle() hook at all three
park sites (idle is a no-op on Windows).
Verified: Linux (.21) clippy -D warnings + 176 punktfunk-host tests green
(incl. the new wiring-plan preference tests); Windows (.173) clippy with
nvenc,amf-qsv --all-targets -D warnings green at this exact tree.
On-glass winbox/Android validation still owed.

Merges 44b71e74 (see its message for the full design: the "Punktfunk Stream
Speaker" Audio/Sink claimed as the session's default output — the crackle
root fix for hardware-sink churn — plus the core-error liveness fix and true
5.1/7.1 capture) across the W1–W8 refactor that landed since the branch
forked:
- punktfunk1.rs was split on main: the audio_thread idle()/drain() hunks are
hand-ported into native/audio.rs (same three sites: reuse-drain comment,
encoder-fail park, end-of-thread park).
- pwinit moved to pf-capture (W6.2): the branch's crate::pwinit calls in
pw_thread and stream_sink.rs become pf_capture::pwinit.
- Kept main's log-tier demotions (stream-state + setup lines at debug)
inside the restructured pw_thread.
Resolution verified on Linux (home-worker-5): clippy -D warnings clean +
173 punktfunk-host tests green at the 691c064a-based equivalent ba5973a2;

Brings the first-frame-latency branch (P0.1 transition tracing, P1.1/P1.2
Welcome-time display prep, P2 in-place resize; pf-driver-proto v3 -> v4 with
IOCTL_UPDATE_MODES) onto current main. The branch predates the W6.2/W7 splits,
so git's rename detection carried most of it into the moved crates
(pf-capture idd_push, pf-vdisplay manager/pf_vdisplay, pf-win-display,
pf-driver-proto, the driver workspace) and the punktfunk1.rs remainder was
re-homed by hand:
- native/handshake.rs: welcome/start trace marks + the Welcome-time display
prep spawn (the prep thread BECOMES the stream thread; hand-off via a
SyncSender<SessionContext>). negotiate() gains bringup/quit/stop and returns
the PrepHandle.
- native.rs: bringup/resize_ms creation + the stop/quit flags hoisted BEFORE
the handshake (the close watcher splits: flags pre-handshake, lifecycle
events post-handshake where `hello` exists); punch_done stamp; the data
plane adopts the prep thread's result or builds inline.
- native/stream.rs: SessionContext/SendStats carry the trace; send_loop
finishes it on the first video packet; the resize path gains the in-place
fast path (try_inplace_resize) with the full rebuild as fallback, restructured
so both share the post-rebuild bookkeeping; prepare_display/PreparedDisplay/
PrepHandle; build_pipeline(+retry) thread the stage marks.
- session_status/mgmt: ttff_ms + last_resize_ms per session (union with the
lifecycle-events fields main added to the same spots).
- pf-capture: Capturer gains capture_target_id() + resize_output() defaults.
- pf-vdisplay manager: perf's faster activation poll (60x50ms) + the settle
floor before the PnP sweep, on main's knobs/no-trait shape.
Also: packaging/windows/build-gamepad-drivers.ps1 is ASCII again (an em-dash
from the pf-mouse work tripped windows-host.yml's locale-safety gate on main).

add publishConfig (unom/npm registry), files, repo metadata, and the
MIT OR Apache-2.0 license; effect becomes a peerDependency (shared instance).
- tsconfig.build.json: emit dist/ JS + .d.ts (bun shebang preserved on the bin).
- .npmrc: map the @punktfunk scope to the registry (no token committed).
- sdk-publish.yml: publish on sdk-v* tags or manual dispatch, reusing the
REGISTRY_TOKEN secret; typecheck/test/build/tag-matches-version gate.
- README: Install section for consumers.
Verified: build green, frozen lockfile stable, bun publish --dry-run packs
@punktfunk/host@0.1.0 (dist + README only) to the unom registry.

Add sdk/examples/virtualhere-dualsense.ts — bind a real USB DualSense (shared
from the couch via VirtualHere USB-over-IP) to the host for the length of each
connection and release it after, for full gyro/touchpad/adaptive-trigger/USB-
rumble passthrough instead of the emulated pad. Brackets on client.connected/
disconnected and releases the pad on SIGTERM for a clean runner stop.
Document it in the Events & hooks page with a zero-code hooks.json variant.

The W6.2 pf-vdisplay extraction (27a5d8da) committed six spots that the pinned
rustfmt (rust-toolchain.toml = 1.96.0) reformats — a short closure collapse and
chain-call wrapping. No semantic change; makes cargo fmt --all --check green so
the combined push does not land CI red on pre-existing format drift.

origin/main landed the shared clipboard (design/clipboard-and-file-transfer.md) while
this branch split quic/msgs.rs -> quic/{caps,control,...} and client.rs ->
client/{mod,control,worker,pump,planes,...} (W7) and deleted the two monoliths. The
feature had modified both deleted files, so its delta is re-applied onto the split
instead of resurrecting the monoliths:
- HOST_CAP_CLIPBOARD -> quic/caps.rs
- MSG_CLIP_* / CLIP_* consts, the six Clip*
structs, and their encode/decode impls -> quic/control.rs (beside the clock codecs)
- CtrlRequest::{ClipControl,ClipOffer} +
Negotiated.host_caps -> client/control.rs
- WorkerArgs.{clip_event_tx,clip_cmd_rx} -> client/worker.rs
- CLIP_EVENT_QUEUE -> client/planes.rs
- NativeClient clip fields, the 7 clip_* /
host_caps / next_clip methods, connect()
channel wiring -> client/mod.rs
- the control-task encode/decode arms and
the clipboard-task spawn -> client/pump.rs
Cargo.lock reconciled (adds pf-clipboard), punktfunk-host/Cargo.toml unions the W6
pf-* subsystem deps with pf-clipboard, and include/punktfunk_core.h is the cbindgen
union (clipboard + rumble C-ABI). punktfunk-core builds --all-features and its 174
lib tests pass, including quic::tests::clip_loopback.

Break the 1747-line clients/android/native/src/decode.rs into a decode/ directory
module (mod.rs + 5 concern submodules):
- decode/setup.rs : codec creation + low-latency config + thread/frame-rate
tuning + HDR static-info encode
- decode/display.rs : DisplayTracker + render-callback registration + HDR dataspace
- decode/latency.rs : realtime clock + decoded-pts / user-flags stat recording
- decode/sync_loop.rs : the synchronous poll decode loop (+ feed/drain) — moved WHOLE
- decode/async_loop.rs : the event-driven async decode loop (+ helpers) — moved WHOLE
decode/mod.rs keeps the consts, DecodeOptions, and the `run` entry point + the
`codec_mime`/`codec_label` re-export, so every crate::decode::X path stays byte-stable.
The module has no decoder struct (free functions + small types), so both decode loops
move byte-for-byte and their separately-inlined received-stat recording is NOT unified.
16 helper fns/types became pub(super) for sibling access; zero field bumps. lib.rs
unchanged (`#[cfg(target_os="android")] mod decode;` resolves to decode/mod.rs).
Verified: cargo-ndk check (aarch64-linux-android, clean) + the gradle cargoNdkDebug
build (arm64-v8a / armeabi-v7a / x86_64). On-device runtime re-verification still owed
per the plan (the two decode loops are a hot path).

Move the macOS `FullscreenController` (NSViewRepresentable that drives native
fullscreen) into its own FullscreenController.swift, and `ApprovalRequest` (the
pending-trust-decision value type) into ApprovalRequest.swift, out of the
1041-line ContentView.swift. Both were file-`private`; dropped to internal so
ContentView (same module) still references them across files. StreamView*.swift
and the connection body are untouched. Pure move; no behavior change.
Verified: `swift build` (macOS) — Build complete.

Break the 2513-line pf-presenter/src/vk.rs into a vk/ directory module (mod.rs +
6 concern submodules), keeping ALL type definitions in vk/mod.rs so every submodule
(a descendant of vk) sees the Presenter/OverlayPipe/etc. private fields with no
field bumps:
- vk/setup.rs : Presenter::new + device/format/present-mode selection
- vk/present.rs : the per-frame present path (present + CSC record + AVVkFrame
sync) — HOT PATH, moved whole
- vk/reconfig.rs : swapchain recreate/resize + HDR reconfiguration
- vk/resources.rs : video-image/staging (re)build + Retired-frame destruction
- vk/overlay_pipe.rs: the presenter-side overlay composite pipeline
- vk/gpu.rs : memory allocation, image barriers, geometry helpers (+ tests)
vk/mod.rs keeps FrameInput/Presenter/OverlayPipe/VideoImage/Staging/Retired/HwCtx*
+ the public accessors + Drop. Methods/free-fns a sibling submodule calls became
pub(super) (~18); zero field bumps, zero re-exports (Presenter/FrameInput never
leave mod.rs). lib.rs unchanged (`pub mod vk;` resolves to vk/mod.rs). The moved
overlay shader include_bytes! gained one `../` for the deeper dir. Pure move; no
behavior change; the hot present path keeps only static pub(super) calls (inlinable).

Break the 1212-line pf-console-ui/src/shell.rs into a facade + shell/ subdir
(shell.rs stays the parent; `mod render;` resolves to shell/render.rs):
- shell/render.rs : the per-frame screen compose/transition path (Shell::render
+ the LayerEnv paint helper)
- shell/overlays.rs : the modal overlays (Shell::draw_overlays + draw_takeover)
- shell/tests.rs : the inline #[cfg(test)] module, extracted verbatim
The Shell struct + its public API + draw_aurora() stay in shell.rs (both children
reach draw_aurora + the private fields as descendants — no bumps). Sole visibility
change: draw_overlays -> pub(in crate::shell) (its caller Shell::render is now a
sibling). Zero re-exports needed (Shell/ConsoleOptions never leave the root). Pure
move; no behavior change.
Verified both platforms: Linux (home-worker-5) clippy -p pf-console-ui

punktfunk-core client/rumble.rs: a per-connection policy engine consumes seq-gated wire
updates and emits EFFECTIVE actuator commands — re-emits on renewals (duration APIs stay
re-armed), self-silences at the v2 lease, a UNIFORM 1 s legacy-host staleness replacing the
per-platform zoo (Apple 1.6 s / Android 60 s / SDL 1.5 s / Deck 1 s), quirk-declared
actuator keepalives (Deck 40 ms + LSB dedupe-defeat jitter), and one stop per buzzing pad
on connection close. Per-pad mailbox semantics: a stalled embedder wakes to ONE current
command, and a stop can structurally never be the update an overflowing queue drops.
New API/ABI: NativeClient::{next_rumble_command,set_rumble_quirks} +
punktfunk_connection_next_rumble_cmd/_set_rumble_quirks (next_rumble/next_rumble2 stay for
un-migrated embedders; both consumers are fed). Migrations DELETE the platform forks:
pf-client-core loses RumbleState + the Deck keepalive loop + LEGACY_RUMBLE_CEILING_MS and
physically silences a slot at close; Android loses the 60 s legacy one-shot (backstop
repack, cancel-on-zero); Apple loses envelopeDeadline + sessionStaleSeconds + both tick
watchdogs (CoreHaptics realization untouched; mac xcframework rebuilt locally).
design/rumble-root-fix.md par. D. Engine 10/10 unit tests; core tests 176 Linux / 175
Windows + clippy -D warnings; swift build + RumbleTuningTests; Kotlin + android-native

B: PadFeedback.game_drove -> rumble_drove, keyed on vibration-asserting reports — an
LED/adaptive-trigger stream can no longer feed the abandoned-rumble force-off while a
coalesced stop never re-asserts (the confirmed unbounded stuck-ON path). C: Linux parity —
every UHID backend now arms the shared watchdog (Steam Input drives these pads over hidraw
with Windows abandonment semantics) and the uinput mixer force-stops abandoned
infinite-replay FF effects (FfState, unit-tested). Shared PUNKTFUNK_RUMBLE_IDLE_MS hatch
(0 = off; non-zero floored above SDL's ~2 s rumble resend).
A: PadShm v2.1 — a 1024 B tail extension carrying an 8-slot lossless output-report ring,
feature-negotiated via zeroed reserved fields (out_ring_ver; deliberately NO
GAMEPAD_PROTO_VERSION bump — mixed generations degrade to the legacy latest-report slot
instead of failing closed). The pf-dualsense driver dual-writes both planes
(publish_output); the host's shared OutputDrain drains oldest->newest with a torn-read
recheck and an overflow->resync path (PadFeedback.resync force-stops + re-arms dedups).
pf-umdf-util grows a min_data_size map fallback. Ds*Feedback.fresh removed (dead).

Break the 1974-line pf-client-core/src/video.rs into flat sibling modules
(matching the crate's video_d3d11.rs / video_pyrowave.rs convention), leaving
video.rs as the contract + Decoder dispatch facade:
- video_color.rs : ColorDesc + csc_rows (the Y'CbCr->RGB matrix)
- video_software.rs : the libavcodec/swscale SoftwareDecoder
- video_vaapi.rs : the Linux-only VAAPI/DRM-PRIME backend (mod is cfg(linux))
- video_vulkan.rs : the FFmpeg Vulkan Video backend
Every crate::video::X / video::X path stays byte-stable (ColorDesc + csc_rows
re-exported from video.rs; frame POD, VulkanDecodeDevice, QueueLock, Decoder,
decodable_codecs*, ffmpeg_codec_id, fourcc/drm_fourcc_for all stay in video.rs).
Code-driven placements: averr, AVERROR_EAGAIN, frame_is_keyframe stay in video.rs
(shared by all three decoders); DrmFrameGuard's field + drm_fourcc_for +
Software/Vaapi/VulkanDecoder ctors/decode became pub(crate) (sibling access);
the test module split three ways (software tests need private decoder internals).
Pure move; no behavior change.
Verified on Linux (home-worker-5): cargo clippy -p pf-client-core (default
[pyrowave] + --no-default-features, --all-targets -D warnings) + cargo test.
Windows verify BLOCKED environmentally: pf-client-core -> sdl3 build-from-source
-> CMake/CL.exe fails on winbox's non-ASCII home path (fails the baseline too,
independent of this split); the split's Windows surface (facade cfg(windows) bits
+ video_d3d11) is verbatim-preserved.

The NSPasteboard bridge completing Phase 1 (design/clipboard-and-file-transfer.md
§5) — with the host backends on this branch, copy/paste now crosses the wire in
both directions on macOS. Lazy in both directions:
- PunktfunkConnection grows the clipboard plane: its own clipboardLock (close()
joins it like the other pullers), hostCaps/hostSupportsClipboard from the
Welcome, the typed ClipEvent vocabulary, and the six ABI wrappers
(clipControl/clipOffer/clipFetch/clipServe/clipCancel/nextClipboard — borrowed
event payloads copied out before the next poll).
- ClipboardSync (PunktfunkKit, macOS-only): one drain thread bridging
NSPasteboard.general ↔ the QUIC clipboard plane. Local copies announce format
lists via a 500 ms changeCount poll (+ immediate on app activation); bytes
leave only on a host FetchRequest, answered from the live pasteboard and
seq-guarded against staleness. Host copies install one NSPasteboardItem whose
data provider fires only when a Mac app actually pastes, then blocks its
provider thread (never main) on a 10 s-bounded fetch. Concealed/Transient
pasteboards (password managers) are never announced; our own writes are
changeCount-suppressed (§3.4). Text/RTF/HTML/PNG; files ride Phase 2.
- UI: per-host "Share clipboard with this host" toggle (StoredHost.clipboardSync,
optional for saved-JSON forward-compat — wire-format tests extended), a
mid-session Share/Stop Sharing Clipboard item in the Stream menu (⌃⌥⇧C,
greyed without HOST_CAP_CLIPBOARD), SessionModel owning the lifecycle
(start on streaming after the trust gate, drain joined off-main on teardown).
swift build + swift test green (macOS). Requires the ABI v8 xcframework
(scripts/build-xcframework.sh).

Turn the 2674-line client.rs into a client/ directory module (mod.rs facade +
8 submodules) behind glob/`use self::` re-exports, so crate::client::X paths
(NativeClient, ProbeOutcome, AudioPacket, display_hdr_env_override) stay
byte-stable. Leaf lifts: frame_channel.rs (the FIFO hand-off + jump-to-live
consts + DecodeLatAcc), recovery.rs (RfiRecovery loss-range detector),
probe.rs (ProbeState/ProbeOutcome), planes.rs (side-plane queues + AudioPacket),
control.rs (CtrlRequest/Negotiated), worker.rs (WorkerArgs + reject_from_close),
pairing.rs (NativeClient::pair). The per-frame pump moves WHOLE as a plain
`pub(super) async fn run_pump` (was worker_main) — the only edit is the
signature line: no trait object, no Box, no per-frame allocation or indirection.
NativeClient + its public impl + Drop + the cfg-gated thread-pin/hot-tid helpers
stay in the facade. Visibility bumps are pub(crate) (struct + each field for
WorkerArgs/Negotiated/ProbeState; FrameChannel + each method); reject_from_close
is pub(crate) (sibling access). No behavior change.
Verified: Linux clippy (quic + no-default, -D warnings) + full cargo test;
Windows clippy (both) + test --lib; macOS clippy (apple thread-pin variant) +
165 lib tests. On-glass jump-to-live + ABR smoke still owed (pump is a pure
relocation, so this is a formality) per the plan's pump gate.

Break the 1302-line quic/msgs.rs into four flat sibling modules behind the
quic facade's glob re-exports, so every crate::quic::X path stays byte-stable:
handshake.rs (Hello/Welcome/Start + codecs), caps.rs (video-cap bits, codec &
chroma negotiation, ColorInfo), control.rs (typed CTL_MAGIC messages + frame),
pairing.rs (SPAKE2 ceremony messages). msgs.rs is deleted; quic/mod.rs gains the
four `mod`/`pub use` lines and the `pub use crate::reject::*` hoist (moved up from
msgs.rs). Pure move; no wire-format or behavior change. Private helpers
(truncate_to, put_bytes, get_bytes) stay with their sole callers; no visibility
changes.
Verified both platforms from clean HEAD snapshots: Linux clippy (quic +
no-default, -D warnings) + full cargo test (157 lib + integration); Windows
clippy (both) + test --lib (156).

The host half of the shared clipboard (design/clipboard-and-file-transfer.md §4),
ported from feat/shared-clipboard (6bd8c18b) into the post-W6 crate shape: the
backends land as a pf-clipboard subsystem crate (the pf-inject/pf-capture
pattern) instead of growing punktfunk-host back out, and the ~340-line
punktfunk1.rs integration is re-implemented against the native.rs/control.rs
split that replaced it.
pf-clipboard:
- host::wayland — ext-data-control-v1 (KWin / wlroots / Sway / Hyprland).
- host::mutter — GNOME via Mutter's *direct* org.gnome.Mutter.RemoteDesktop
clipboard (no data-control at any GNOME version; the xdg portal needs an
interactive grant a headless host can't answer).
- host::windows + host::winfmt — Win32 clipboard on a hidden message-loop
window: WM_CLIPBOARDUPDATE listener + OLE delayed rendering (WM_RENDERFORMAT)
for text / CF_HTML / RTF / PNG.
- host::session — the backend-agnostic coordinator bridging HostClipboard to
the QUIC clipboard plane (offers, fetch accept-loop, remote offers, pastes).
- A portable facade (policy / enabled / cap_advertised / ClipCoordCmd / start /
spawn_decline_loop) so the orchestrator compiles cfg-free on every platform;
ClipCoordCmd moves into the crate (it was host-owned before).
punktfunk-host glue:
- handshake.rs advertises HOST_CAP_CLIPBOARD via pf_clipboard::cap_advertised.
- serve_session starts the coordinator (gated on a real compositor — the
synthetic source stays out of the session clipboard) and spawns the
CLIP_FETCH_UNAVAILABLE decline loop when the policy is on but no backend bound.
- control.rs gains the ClipControl/ClipOffer arms + the host-offer forward
branch, and the e2e session test (cap advertise → ClipState ack with
BACKEND_UNAVAILABLE → fetch decline) rides in native.rs's tests.
Still opt-in default OFF (PUNKTFUNK_CLIPBOARD). Remaining: the macOS client
(design §5) — then this becomes user-visible.

Turn transport/udp.rs into a udp/ directory module: the cross-platform core
(UdpTransport, is_transient_io, spawn_data_punch, the Transport trait impl) stays
in mod.rs; the platform batched-I/O backends move to udp/{linux,windows,apple}.rs.
The trait impl is kept whole -- its per-OS send_batch/send_gso/recv_batch methods
become cfg-gated one-line delegators to pub(super) free fns that take &UdpTransport
(byte-identical bodies, self -> t). transport/mod.rs is unchanged (re-exports still
resolve; udp/mod.rs re-exports windows::send_uso_all). No behavior change.
Module gates: linux = any(linux, android) (Android uses sendmmsg/recvmmsg via its
bionic binding); windows = windows (USO); apple = all(unix, not(any(linux,android)))
(recvmsg_x on Darwin, recv-loop on BSD). GSO stays linux-only.
Verified on all four target families from clean HEAD snapshots: Linux clippy
(quic + no-default, -D warnings) + full test; Windows clippy (both) + test --lib
(156); macOS check (apple recvmsg_x path); aarch64-linux-android check (android_mmsg).

The portable shared-clipboard plane in punktfunk-core, all behind the `quic`
feature (design/clipboard-and-file-transfer.md §3):
- Control messages 0x40–0x44 (ClipControl / ClipOffer / ClipFetch...) and the
HOST_CAP_CLIPBOARD capability bit, negotiated in the Welcome caps.
- Per-transfer QUIC bi-streams ("PKFs" magic) for lazy fetch of offered content,
with ClipFetchHdr status/size framing (quic::clipstream).
- The §3.5 portable wire-MIME vocabulary (text/plain;utf-8, text/html, text/rtf,
image/png) shared by both ends.
- Client-side clipboard task (client.rs) + C ABI surface bumped to v8 (abi.rs,
regenerated include/punktfunk_core.h).
- Loopback transport tests (quic::tests).
No OS clipboard integration yet — that is the host backends (Phase 1/3) and the
macOS client (Phase 1).
Ported from feat/shared-clipboard (af3a7d8c, pre-W6 base) onto current main;
three deliberate deviations from the original commit:
- ABI v6 → v8: main took v6 (reanchor gate) and v7 (typed connect rejection)
in the meantime; the clipboard C surface re-lands as v8.
- CLIP_CANCELLED_CODE 0x60 → 0x70: main's pairing-rejection close codes claimed
the 0x60–0x67 block; the vocabularies stay disjoint on purpose.
- Negotiated.host_caps coexists with main's 6-tuple host_caps plumbing: main
needs the worker-local copy for gamepad snapshots, the clipboard path needs it
across ready_tx to build the NativeClient handle (punktfunk_connection_host_caps).

Turn the 1446-line packet.rs into a packet/ directory module (mod.rs facade
+ header/packetize/reassemble/tests) behind glob re-exports, so every
crate::packet::X path stays byte-stable. Pure move: the header consts +
PacketHeader -> header.rs; Packetizer -> packetize.rs; the Reassembler cluster
(kept WHOLE -- disjoint-borrow hot path) + loss-window consts -> reassemble.rs;
the inline #[cfg(test)] block -> tests.rs. Sole visibility change:
LOSS_WINDOW_NS -> pub(super) (a test imports it). No behavior change.
Verified on both platforms from a clean HEAD snapshot: Linux clippy

Drop Orval for the first-party @effect/openapi-generator (OpenAPI 3.1 ->
Effect Schema + a typed HttpClient client) and bump effect 3.19 ->
4.0.0-beta.98. Port the hand-written surfaces to the v4 API (Result over
Either, Context.Service, Codec, Literals/Union arrays, Stream/Schedule/
Effect renames). Transport (CA-pinning fetch) and the reconnecting SSE
source are kept intact.
Make the SDK approachable for non-Effect users:
- Add pf.api.* on the Promise facade: the generated client surfaced as
typed, Promise-native methods (await pf.api.listPairedClients()), so REST
calls are autocompleted and checked instead of stringly-typed
pf.request(method, path, body) + `as` casts. Zero-drift veneer over
make(httpClient), backed by the same pinning fetch. pf.request stays as
the untyped escape hatch.
- Re-tier examples into a 1-4 complexity ladder, rewritten onto pf.api.*
(the typed payloads caught a wrong `launch` shape in provider-sync);
the Effect example is labelled advanced. Add examples/ to tsconfig so
they are typechecked (stops rot).
typecheck + 19 tests green.

vdisplay.rs + vdisplay/* (the per-compositor Linux backends — KWin zkde-screencast,
wlroots swaymsg, Mutter RemoteDesktop, Hyprland — and the Windows IddCx/pf-vdisplay
driver backend, behind one VirtualDisplay trait; the mode-conflict admission
registry, the display policy/identity/custom-preset state, and the session-env /
gamescope routing) move into crates/pf-vdisplay (plan §W6). The DDC/CI panel-power
control (used only here) and the KWin zkde protocol XML move with it. This
completes the host-crate decomposition: capture, encode, inject, and vdisplay are
now four subsystem crates over the shared leaves, and punktfunk-host is the
orchestrator (serve/supervisor + native + gamestream + mgmt).
Coupling breaks (all down-only, cargo-tree acyclic):
- capture::dxgi identity -> pf_frame::dxgi; win_display/monitor_devnode/
console_session_mismatch -> pf-win-display leaf; can_open_another_session ->
pf-encode (the NVENC session-budget admission gate — acyclic peer edge).
- The registry's DisplayCreated/DisplayReleased emits into the host SSE event bus
invert to a leaf hook: pf-vdisplay emits a neutral DisplayEvent to a
host-registered DISPLAY_EVENT_SINK, so it never reaches the orchestrator's
events module.
- The IddCx driver module is renamed pf_vdisplay -> driver (its old name collided
with the crate name through the host's `mod vdisplay` shim glob).
The host keeps `mod vdisplay { pub use pf_vdisplay::* }` so every crate::vdisplay::*
path (serve/mgmt/native/the capture FrameChannelSender seam) is unchanged; the
heavy deps (wayland/ashpd/tokio + the zkde protocol) moved with the crate.
Co-authored: a fail-closed IOCTL-reply-length security fix (reject short/zeroed
pf-vdisplay driver replies before trusting protocol_version/target_id/wudf_pid/luid,

inject.rs + inject/* (the per-OS injectors — wlroots virtual-input, KWin
fake_input, libei/reis, gamescope-EI on Linux; SendInput on Windows — plus the
virtual-gamepad HID stack: DualSense/DualShock4/Switch Pro/Steam Controller/Deck
over uhid/usbip and the Windows UMDF drivers, the proto codecs, the injector
service, and the uhid manager) move into crates/pf-inject behind the
InputInjector trait (plan §W6). It consumes punktfunk_core::input (the neutral
GamepadEvent/InputEvent vocabulary, moved to core in W5) + the pf-driver-proto
wire contract, and reaches pf-capture only for the Windows gamepad-channel
WUDFHost check + the resident-mouse compose-kick hook.
The one inject->vdisplay coupling (the libei gamescope-EI backend needs the EIS
relay socket path) is broken via a leaf: gamescope_ei_socket_file moves to
pf-paths as the shared contract — the gamescope producer (host vdisplay) keeps
its session-env-lock wrapper around it, the libei consumer (pf-inject) reads it
directly post-retarget. The host keeps a `mod inject { pub use pf_inject::* }`
shim so every crate::inject::* path (the native/gamestream input planes + devtest)
is unchanged; the heavy input deps (wayland/reis/xkbcommon/usbip + the KWin
fake-input protocol XML) moved with the crate.

The final piece of the lid-closed field report (fixes 1-3: 3d9b3290;
prerequisites: 85dd2bb0 pf-mouse, 845a9760 leaf primitives, 94ca4041
pf-capture hook): the IDD first-frame gate can only pass if DWM composes
at least one frame, and a lid-closed/locked/idle machine is exactly the
state Windows has decided not to compose in. The SendInput compose kick
is conditional on this process's context — wrong session → wrong input
queue; secure desktop → blocked; display powered off → no wake. A report
from the resident pf-mouse HID device is REAL input to win32k:
session-independent, secure-desktop-proof, wakes a powered-off display,
counts as user presence. Parsec-class mechanism, and semantically honest
— a remote user starting a stream IS a user arriving at this machine.
- hid_kick(rect, bounds): newest-wins kick slot + condvar, serviced by
the keeper thread that owns the ONE process-wide VirtualMouse (a
second open() would squat the bootstrap mailbox). Not-ready (opt-out,
driver missing, not yet attached) returns false → the capture crate
falls back to SendInput.
- perform_kick: park the pointer at the target display's center, dwell
35 ms (Stage-W3: DWM samples cursor position at the next vsync tick;
the gaps also keep reports from coalescing in the driver's 8 ms
timer), wiggle ~2 px, restore the saved position. Desktop→HID
coordinates normalize against pf_win_display::desktop_bounds() (CCD
union — correct from any session, unlike per-session GDI metrics).
- ensure_resident registers the hook (pf_capture::HID_COMPOSE_KICK) —
the one-way-edge inversion: pf-capture never reaches into inject.
- keeper loop: condvar wait (250 ms tick) so a kick executes
immediately, not at the next tick; publishes MOUSE_READY from
driver_proto.
Paired with pf-frame's DisplayWakeRequest (held by the capturer from
before the first-frame gate): the power request keeps the display from
going dark mid-session, the HID kick wakes it when it already is.

capture/linux (PipeWire portal) + capture/windows (IDD direct-push: dxgi
mechanics, idd_push + submodules, synthetic_nv12) + pwinit move into
crates/pf-capture behind the Capturer trait + synthetic sources (plan §W6).
The crate speaks pf-frame (CapturedFrame/PixelFormat + the DXGI identity),
pf-zerocopy (CUDA import), and the pf-win-display leaves, and NEVER pf-encode —
the capture->encode edge is one-way. This completes the deliberate capture/encode
crate split (the invasive path the plan had merged into one pf-media): capture
and encode are now separate subsystem crates sharing only pf-frame.
Four seams keep the capturer off the orchestrator:
- VirtualOutput is EXPLODED into primitives (remote_fd/node_id/preferred_mode/
keepalive) by the host facade, so pf-capture never depends on the vdisplay type;
- FrameChannelSender: the sealed-channel delivery is a Send+Sync closure the host
facade builds from the pf-vdisplay control device + send_frame_channel IOCTL and
hands in; ChannelBroker holds the closure instead of the control HANDLE (the
whole-desktop handle-duplication security boundary is byte-for-byte unchanged);
- console_session_mismatch + desktop_bounds live in pf-win-display (leaf peers);
- pwinit moves here (audio caller -> pf_capture::pwinit).
The host keeps capture.rs as a thin BRIDGE: it re-exports the vocabulary + capturer
types (every crate::capture::* path is unchanged) and keeps open_portal_monitor /
capture_virtual_output, which resolve the ZeroCopyPolicy + FrameChannelSender and
call into pf-capture. verify_is_wudfhost + install_gpu_pref_hook are re-exported
(the gamepad-channel bootstrap + the main.rs subcommand consume them).
Co-developed: the resident-HID-mouse compose-kick hook (HID_COMPOSE_KICK + the
HID-first cursor kick + _display_wake) rides this commit into pf-capture; the host
mouse_windows registration side lands separately on top.
Verified: Linux clippy -D warnings (pf-capture + host nvenc,vulkan-encode,pyrowave

Three leaf-crate additions the IDD-push capturer (pf-capture, plan §W6 C6)
builds on — committed ahead so the capture-crate extraction and the HID
compose kick can land on top:
- pf-frame session_tuning::DisplayWakeRequest — RAII PowerCreateRequest/
PowerSetRequest(PowerRequestDisplayRequired + SystemRequired), the
service-grade 'someone is watching this screen' assertion (visible in
powercfg /requests), held for a capture session so the console cannot
drop into display-off mid-stream. Object-lifetime, unlike the
thread-bound ES_* flags in on_hot_thread. Prevention only: no power
request turns an already-off display back on — that wake is input's
job (the virtual-mouse compose kick).
- pf-win-display win_display::desktop_bounds() — the virtual-desktop
bounds as the union of every ACTIVE CCD path's source rect. From the
CCD database (global), NOT GetSystemMetrics (a per-session view), so
a non-console-session host still aims HID absolute coordinates at the
console's real layout.
- pf-win-display console_session_mismatch() — the session guard from
3d9b3290, copied into the leaf so pf-capture reads it as a peer
instead of reaching into the orchestrator (relocation authored by the
W6 extraction session).

Headless Windows hosts (no dongle) stream an INVISIBLE cursor: with no
pointing device present win32k reports SM_MOUSEPRESENT=0 and DWM never
composites a pointer into the pf-vdisplay frame, even though SendInput
moves it. Keep ONE virtual HID mouse devnode alive for the host's
lifetime — the Sunshine/Parsec-class fix, zero client changes.
- pf-mouse: UMDF2 HID minidriver, one fixed identity (PF:MO 5046:4D4F,
obviously virtual, nothing fingerprints it), one 8-byte input report
(5 buttons + absolute 15-bit X/Y + wheel + AC-pan). Transport is the
sealed pad channel verbatim (Global\pfmouse-boot-0 mailbox + unnamed
MouseShm DATA section) so pf-umdf-util's audited layer serves it
unchanged; report delivery is event-driven (idle = no HID traffic).
- host: inject::mouse_windows — VirtualMouse (SwDeviceCreate'd devnode +
channel), ensure_resident() keeper thread started by every
InjectorService (process-wide, PUNKTFUNK_NO_VIRTUAL_MOUSE opts out),
vmouse-spike on-glass validation (cursor sweep via HID reports).
- proto: mouse module (magic, boot-name, identity, report layout,
unit-tested input_report packing).
- SwDeviceProfile grows container_tag so the mouse's ContainerId family
(PFMO) never groups with a pad's (PFDS) in the Devices UI.
- packaging: pf-mouse rides the gamepad-driver build + install pipeline
(build-gamepad-drivers.ps1, windows-drivers.yml, driver install
--gamepad picks up every staged .inf).
On-glass validated on winbox: devnode + HID child bind, SM_MOUSEPRESENT=1
with no physical mouse, cursor sweeps via HID reports (vmouse-spike).
This work was implemented in a parallel session; committed here as the
build prerequisite for the HID compose kick that follows.

Field report (Windows laptop, lid closed, Tailscale): v0.12.0's activation
fix works — the pf-vdisplay target activates in ~200ms — but the session
still dies at the first-frame gate: 'driver_status=1 but no frame published
within 4s'. Triage showed three independent blind spots; this names all of
them at their source instead of guessing downstream:
- pf-win-display: decode ChangeDisplaySettingsExW failures (-1 FAILED — a
display write rejected, the wrong/remote-session signature — vs -2 BADMODE,
which the old 'mode not advertised?' text conflated), and WARN on every
non-zero SetDisplayConfig rc in the CCD isolate even when verification
passes vacuously (the lid-closed case: nothing else active, so the INFO
swallowed rc=0x5 ERROR_ACCESS_DENIED while the load-bearing COMMIT_MODES →
ASSIGN_SWAPCHAIN re-commit silently never applied). Access-denied rcs get
the remedy appended (console session / installed service).
- host: console-session guard (interactive::console_session_mismatch) — a
host outside the active console session (a hand-launched host after an RDP
round-trip) fails every display write, reads the wrong session's GDI view,
and its SendInput compose kicks go nowhere. Named ERROR at vdisplay
acquire + appended to the first-frame timeout, instead of the misleading
generic failure. (The idd_push diagnosis half of this landed in 9a36ea21;
this commit adds the proto helpers + session guard it references, healing
the windows-cfg build.)
- proto + driver: while OPENED, driver_status_detail now carries a live
packed word (bit31 live-marker | offered 15-bit | mismatch-dropped 16-bit)
maintained by the publisher, so the host's first-frame timeout can tell
apart: never-attached (no swap-chain worker ran), attached-but-DWM-composed-
zero-frames (undamaged/powered-off desktop, kicks blocked on the secure
desktop), and composed-but-every-frame-mismatched (ring sized from a stale/
foreign-session GDI mode). Zero layout change, old drivers read as 'no
detail'; unit-tested pack/unpack in pf-driver-proto.

encode.rs + encode/* (NVENC, VAAPI, native AMF, AMF/QSV ffmpeg, direct-SDK
NVENC/CUDA, raw Vulkan-Video, PyroWave, openh264) move into crates/pf-encode
behind one Encoder trait + open_video selector (plan §W6). The crate speaks the
shared frame vocabulary (pf-frame: CapturedFrame/PixelFormat + the DXGI identity
D3d11Frame/make_device) and pf-zerocopy (CUDA context/buffers), and NEVER
pf-capture — the capture→encode edge is one-way (ZeroCopyPolicy, prior commit).
Dep moves: the heavy encoder deps (ffmpeg-next, the NVENC SDK, openh264,
pyrowave-sys) move from the host to pf-encode; the host's
nvenc/amf-qsv/vulkan-encode/pyrowave features now FORWARD to pf-encode/*. The
host keeps a mod-encode shim (pub use pf_encode) so every crate::encode::* path
(negotiator + GameStream/native/mgmt planes) is unchanged.
resolve_render_adapter_luid moves from the host's windows/win_adapter.rs into
pf-gpu (both pf-encode and pf-capture need it as a peer of GPU selection); its 5
call sites (encode amf/nvenc, capture idd_push/synthetic_nv12, vdisplay manager)
rewire to pf_gpu::resolve_render_adapter_luid and win_adapter.rs is deleted.
pf-frame's make_device gains a # Safety section (public-unsafe-fn lint, latent

The PipeWire capture thread re-derived three encode-backend facts by calling
encode::{linux_zero_copy_is_vaapi, resolved_backend_is_gpu,
pyrowave_capture_modifiers} — a capture→encode back-reference that would force
pf-capture to depend on pf-encode (and vice versa, since encode already speaks
the frame vocabulary). Resolve them ONCE in the host capture facade (which may
reach crate::encode) as a ZeroCopyPolicy { backend_is_vaapi, backend_is_gpu,
pyrowave_modifiers } and thread it into PortalCapturer::open /
from_virtual_output → spawn_pipewire → pipewire_thread.
capture/linux/mod.rs now makes ZERO crate::encode calls — the edge is one-way
(plan §2.4 / §W6), so pf-capture can be extracted depending only on pf-frame
(not pf-encode). pyrowave_modifiers is computed by the facade whenever the
encoder pref is pyrowave (which implies the VAAPI backend); the thread still
consumes them only inside its existing vaapi_passthrough guard, so behavior is
unchanged.

windows/{win_display,monitor_devnode,display_events}.rs move into
crates/pf-win-display: the CCD/GDI path-activation + mode-set + HDR
advanced-colour + source-rect helpers, the PnP monitor-devnode enable/disable
lever, and the WM_DISPLAYCHANGE / device-arrival watch. The coming pf-capture
crate's IDD-push capturer consumes all three; the host's pf-vdisplay backend
consumes win_display + monitor_devnode. A leaf lets both depend on them as a
PEER instead of the capturer reaching back into the orchestrator (plan §W6).
win_display's one external tie (crate::vdisplay::Mode) becomes the underlying
punktfunk_core::Mode; the cluster is otherwise self-contained (pf-paths for the
state file, serde_json for it, windows). pub(crate) items bump to pub at the
boundary; win_display carries a module-level allow(missing_safety_doc) to keep
the pre-carve behavior (the FFI helpers were pub(crate) unsafe fn with prose
safety docs — the lint only fires once they're pub, and this is an internal
publish=false leaf). The host imports the three modules at its crate root, so
every crate::{win_display,monitor_devnode,display_events}::* path is unchanged.

The captured-frame types both capture (producer) and encode (consumer) speak —
PixelFormat, OutputFormat, CursorOverlay, CapturedFrame, FramePayload,
DmabufFrame, drm_fourcc — move into crates/pf-frame, alongside the small pure
helpers that ride the same seam: hdr (HDR static metadata / in-band SEI),
metronome (the metronomic-stall detector), thread_qos (per-thread scheduling
QoS), session_tuning (Windows process tuning), and the Windows DXGI capture
IDENTITY (WinCaptureTarget, D3d11Frame, pack_luid, make_device + the GPU
scheduling-priority hardening it applies) (plan §W6).
This is the crate that breaks the capture<->encode cycle: FramePayload's GPU
variants own their backends from BELOW (Cuda -> pf_zerocopy::DeviceBuffer,
D3d11 -> dxgi::D3d11Frame), so encode can speak the vocabulary without a path to
capture, and vice versa. The Windows DXGI identity moving here lets capture,
encode, and pf-vdisplay share ONE WinCaptureTarget/device factory instead of the
old capture<->encode<->vdisplay reach-in.
The host keeps thin facades: capture.rs re-exports the vocabulary
(crate::capture::{PixelFormat,…} unchanged); capture/windows/dxgi.rs keeps the
win32u GPU-preference hook + HDR/video-engine converters + self-test and
re-exports the identity; native.rs re-exports boost_thread_priority from
pf_frame. crate::hdr/metronome/session_tuning callers rewired to pf_frame::*.
metronome's Metronome::new gained a Default impl (new_without_default fires once
the type is public across the crate boundary).

The controller's target is only a promise: on calm content the encoder
emits a fraction of it, every window looks clean while proving nothing,
and the climb drifts the target into rates the decoder has never seen.
The first motion spike is then the first real test — it fails, and the
decoder is overloaded for the two-window backoff latency (the reported
settle-calm-then-spike stutter).
Three changes, all client-side (no wire/ABI impact, old hosts unaffected):
- Climb gate: a clean window authorizes a climb only when its ACTUAL
delivered throughput reached 3/4 of the current target — the target was
genuinely tested. Calm windows still bank clean credit; the first
loaded window after a clean run climbs immediately.
- Proven-throughput cap: climbs step at most x1.5 past the session's
high-water mark of delivered-and-digested (decode-latency-flat)
throughput, so slow start becomes a bounded experiment instead of a
blind doubling. High-water never decays: calm periods keep a validated
target, so returning motion gets the full rate instantly; shrinking
capacity (thermals) stays the reactive decode signal's job.
- Severe decode excursion: a >45 ms-over-baseline decode spike backs off
after ONE window instead of two — the overload is already on screen.
The pump feeds the window's wire-byte throughput; the byte baseline is
rebased when the startup capacity probe completes so FLAG_PROBE filler
can't poison the proven mark with the link rate.

linux/zerocopy/* (CUDA context/buffers + EGL/Vulkan dmabuf import + the isolated
import worker) and linux/dmabuf_fence.rs move wholesale into crates/pf-zerocopy,
so the coming pf-frame vocabulary crate (FramePayload::Cuda owns a DeviceBuffer)
and the pf-encode/pf-capture subsystem crates can reach the GPU plumbing without
the host orchestrator in between (plan §W6). Content stays Linux-only; the crate
compiles to an empty lib elsewhere, so dependents carry a plain dependency.
drm_fourcc deliberately does NOT move: it consumes the frame vocabulary
(PixelFormat), which sits ABOVE pf-zerocopy — it lives with capture for now and
moves into pf-frame next. cuda's ffi re-export bumps pub(crate)->pub (the raw
CUdeviceptr vocabulary is consumed across the crate boundary by the encode
backends). A crate::zerocopy shim module keeps every existing path valid until
capture/encode themselves move out.

Fourth de-coupling for the host crate carve (plan §W6.1 leaf). gpu.rs (inventory,
selection preference, active-session accounting — deps only pf-host-config + pf-paths, no
subsystem refs) moves to a new pf-gpu leaf so pf-encode/pf-capture/pf-vdisplay can consult
the selected GPU without an orchestrator edge. ~50 crate::gpu:: sites repoint to pf_gpu::;
the ~30 pub(crate) items become pub (crate API). assign_ids gets a macOS-only
allow(dead_code) (used only by the Linux/Windows enumerate arms).

Third de-coupling for the host crate carve (plan §W6.1 leaf). HostConfig + the config()
OnceLock (config.rs, pure std, zero deps) move to a new pf-host-config leaf so every
subsystem crate (pf-encode/pf-capture/pf-vdisplay/pf-gpu) can read process config WITHOUT
depending on the orchestrator. 34 crate::config::config() call sites across 19 files
repoint to pf_host_config::config(). thread_qos stays in the host for now (it calls
session_tuning::on_hot_thread — its own leaf-ification rides the encode carve).
Granular-crate decision (supersedes the plan's single pf-media): split capture/encode/
vdisplay into separate crates rather than one broad crate — the capture↔encode cycle is
broken by a shared frame-types leaf, and vdisplay→encode (can_open_another_session) is a
legal one-way edge since encode never references vdisplay.

Second de-coupling for the host crate carve (plan §W6.1 leaf). config_dir /
create_private_dir / write_secret_file (+ the Windows DACL helpers) were pub(crate) in the
gamestream junk drawer, yet consumed by vdisplay, stats, gpu, library, mgmt_token,
native_pairing and the Windows service — many of which become pf-media / pf-vdisplay, for
which crate::gamestream would be an illegal upward edge. New leaf crate pf-paths (pure std

keeps only its own concerns.

Finishes the gamepad-vocabulary un-coupling (plan §W6.0): the Linux uinput button map now
names BTN_* straight from punktfunk_core::input::gamepad instead of the crate::gamestream
re-export aliases, so pf-inject will carry no edge into the gamestream junk drawer for
gamepad constants. Removes the now-dead alias block; the wire-bit pinning test
(gamepad_wire_bits_are_pinned) pins core directly (equally strong — core is the single
source). gamestream keeps only the decode path, which imports the types from core.

First de-coupling for the host crate carve (plan §W6.0 / §2.4): the GameStream
(Moonlight-plane) decoded controller types were defined in gamestream/gamepad.rs — the
"junk drawer" — yet consumed 18× by the platform-neutral input injectors AND by the
Moonlight decode path. Once inject becomes pf-inject, reaching them via crate::gamestream
would be an illegal upward edge. Move the two types to core::input (below both planes;
inject already depends on core) and repoint every consumer. Also consolidate the
duplicated MAX_PADS onto the existing core::input::MAX_PADS. The gamestream BTN_* const
aliases stay for now (separate follow-up); decode()/rumble/tests remain in the Moonlight
plane, now importing the types from core.

The optional supervision layer (RFC §8): one service runs everything in
<config_dir>/scripts/ plus installed punktfunk-plugin-* packages
(<config_dir>/plugins/node_modules/), as Effect fibers.
- Plugins (a definePlugin default export, either main shape) are
SUPERVISED: a failure restarts them with capped exponential backoff
(jittered, 1s→60s); a clean return completes them. The Effect shape
runs under the PunktfunkHost layer; the async-fn shape gets a facade
client whose close is scope-guaranteed.
- Bare scripts are one-shot: importing them is the run, no restart
(export a plugin to be supervised).
- Shutdown is STRUCTURAL: SIGINT/SIGTERM interrupt the whole fiber tree,
so Effect plugins' scoped finalizers run and clients close before
exit — the systemctl-stop story, and the reason the Effect plugin
shape exists at all.
- The sshd rule applies to unit files (world-writable → refused loudly);
cache-busted imports make restarts real; --list for inventory.
6 new bun tests (17 total green): discovery + refusal, both plugin
shapes against a mock host, crash→restart with backoff, one-shot
semantics, and finalizer-on-interrupt. Live-verified against a real
host: a supervised watcher plugin received library.changed through the
pinned tunnel, and SIGTERM shut the tree down structurally (exit 0).
Deferred to the packaging follow-up (release.yml is in flight in a
parallel session): the vendored-Bun deb/rpm/iss packages and the
host-log-ring tee (needs a host ingest endpoint); console page rides
the other console surfaces.

External game-library providers become first-class (RFC §8): a plugin
computes its desired title list and PUTs it — the host owns the diff.
- CustomEntry gains `provider` + `external_id` (API-set only; never on
manual entries). GameEntry surfaces `provider` for console attribution
and the new `GET /library?provider=` filter.
- PUT /api/v1/library/provider/{p}: atomic declarative reconcile keyed
on the provider's `external_id` — host ids stay stable across syncs,
orphans drop, manual entries and other providers are never touched,
an empty array clears the set. Validated: provider id [a-z0-9._-]
(`manual` reserved), unique non-empty external_ids.
- DELETE /api/v1/library/provider/{p}: clean uninstall, returns the
removed count.
- Ownership is unambiguous both ways: manual CRUD now returns 409 for a
provider-owned entry (MutateOutcome::ProviderOwned) instead of letting
an edit be silently clobbered at the next sync.
- library.changed now carries the mutating source (`manual` or the
provider id) — hooks and the SDK filter on it.
- Spec + SDK schemas regenerated; sdk/examples/provider-sync.ts is the
provider-plugin skeleton.
347 host tests green (pure reconcile: stable ids, orphan drop,
idempotence, bystanders untouched; name/payload validation; route 400s)
+ 11 SDK tests. Live-verified end to end THROUGH the SDK against a real
host: sync → filtered list → manual-delete 409 → re-sync with stable id
+ orphan drop → uninstall (removed=2), with three
library.changed(source=romm) events observed on the live stream.

New top-level sdk/ package (RFC §7): a typed management-API client plus
the lifecycle event stream, built on Effect, two surfaces over one core:
- @punktfunk/host — the Promise facade front door: connect() resolves
URL/token/TLS pin from the host's own files (zero config on the box),
fails fast on bad credentials, pf.events.on() with typed callbacks
(exact kinds, domain.* prefixes, "*", "dropped", "unknown"),
pf.request() for the REST surface. Effect never required.
- @punktfunk/host/effect — the PunktfunkHost service + PunktfunkHostLive
layer, Stream-based events()/eventsRaw(), typed errors
(AuthError | ApiError | TransportError | VersionSkew — a 2xx that
fails its schema is a typed skew, not undefined later), and every
wire shape as an effect/Schema: REST generated via orval
client:'effect' from api/openapi.json (S3 spike: works well; the
text/event-stream payload is out of its reach), events hand-mirrored
from the host's snapshot-tested wire format as a kind-discriminated
union.
One reconnecting SSE core under both surfaces: spec-shaped parser,
exponential+jittered backoff (capped, resets after a healthy
connection), Last-Event-ID resume, 401 terminal. Default is LIVE tail
only — a fresh notify script must not re-fire on the host's replayed
ring (since: 0 opts into full replay).
TLS: the pin trusts exactly the host's self-signed identity cert
(chain-verified; hostname check waived — the cert is deliberately
CN-only for fingerprint pinning). Bun via fetch tls, Node via an undici
dispatcher (optionalDependency).
definePlugin() accepts both main shapes (async fn | Effect requiring
PunktfunkHost). Examples in both styles; README carries the compat
contract + systemd/Task Scheduler templates.
11 bun tests green (wire decode against the Rust snapshot strings,
SSE parser/reconnect/Last-Event-ID/401, both surfaces vs a mock host).
Live-verified against a real host on Bun AND Node through the pinned
loopback hop: connect → REST mutate → live event received → resume
cursor advanced; a wrong CA is rejected. npm publish + CI wiring
deferred (npm org = RFC open question 1).

The capture.rs facade no longer re-derives the encode backend. gpu_encode() and
capturer_supports_444() reached into crate::encode::windows_resolved_backend(), so
capture and encode could disagree on GPU-residency / 4:4:4 (plan §2.4). Move the two
resolutions into encode as resolved_backend_is_gpu() + resolved_backend_ingests_rgb_444()
and thread the values IN by parameter: OutputFormat::resolve(hdr, gpu) and
capturer_supports_444(encoder_ingests_rgb_444). Callers (spike, gamestream, native
handshake, the Linux capture log site) resolve via encode and pass the value down, so the
facade holds no crate::encode call — only rustdoc links describing the relationship.

Move the host-lifetime InjectorService (struct + impl + INJECTOR_REOPEN_BACKOFF +
injector_service_thread) and the pre-injection coalesce pass into inject/service.rs,
alongside the coalesce unit tests. libei_ei_source stays in the facade as an open()
helper. Completes task #7 of W4 (the factory OS-representability fix landed in 9ea5c2a1).

Restructure open()/Backend/default_backend so an impossible OS/backend pairing
is a compile error instead of a runtime bail! (plan §2.3). Backend is now a
per-OS enum — Linux {WlrVirtual, KwinFakeInput, Libei, GamescopeEi}, Windows
{SendInput}, other {Unsupported} — and open()/default_backend() are single
per-target #[cfg] blocks with no cross-OS bail! arms.
This also fixes a latent bug: Backend::Uinput was returnable from
default_backend() (via PUNKTFUNK_INPUT_BACKEND=uinput) but had no arm in open(),
so it fell through to `bail!("not implemented")` — a runtime failure. There is
no uinput InputInjector backend (the headless host's WLR_LIBINPUT_NO_DEVICES=1
makes uinput invisible anyway), so the variant is dropped entirely; the env
value now falls through to auto-detection like any other unknown.
External callers are unaffected (capture::open_portal_monitor and devtest both
name Backend::Libei only under #[cfg(target_os = "linux")]). Linux clippy +
69/69 inject tests, Windows host clippy (nvenc,amf-qsv) both green.

Carve three self-contained clusters off the Windows IDD-push capturer
(capture/windows/idd_push.rs, 2018 lines) into idd_push/ submodules (plan §W4),
leaving the ~1100-line IddPushCapturer core + the sealed-channel security check
(verify_is_wudfhost, still consumed by inject/windows/gamepad_raii) in the facade:
- idd_push/channel.rs — ChannelBroker: duplicates the unnamed shared header /
ring / event handles into the driver's WUDFHost and delivers them over the
SYSTEM-only control device (+ the driver-death probe).
- idd_push/descriptor.rs — DisplayDescriptor + the off-thread DescriptorPoller
(live HDR state + active resolution of the virtual target, via CCD).
- idd_push/stall.rs — Stall + StallWatch: the DWM-composition-hole diagnostic.
Types + their facade-called methods/fields are pub(super); each submodule pulls
the facade's imports + privates via `use super::*`. Pure move; no behavior
change. Windows host clippy (nvenc,amf-qsv, all-targets) + fmt green.

Split the zero-copy EGL backend (linux/zerocopy/egl.rs, 1208 lines) into a
facade + egl/gl.rs (plan §W4 / §3.2). gl.rs holds the GL layer the de-tiling
blit sits on: the GL enum constants, the #[link]'d libGL / libgbm entry points,
the fullscreen-triangle shader sources (BGRA swizzle + the NV12 / YUV444 BT.709
convert passes), and the shader/program compile helpers. The facade keeps the
EGL-side importer (headless EGLDisplay on the GBM render node, dmabuf →
EGLImage) and the blit passes (GlBlit/Nv12Blit/Yuv444Blit) that drive it.
Pure move; no behavior change. Linux clippy --all-targets + fmt green.

Split the zero-copy CUDA backend (linux/zerocopy/cuda.rs, 1843 lines) into a
facade + cuda/ffi.rs (plan §W4 / §3.2). ffi.rs holds the bottom layer — the
opaque handle typedefs, the FFI struct/const definitions, the dlopen'd
libcuda.so.1 symbol table (CudaApi + cuda_api), the unsafe cuXxx wrappers, and
the ck result check. The facade keeps the higher-level state that drives it: the
process-wide CUcontext, device buffers/BufferPool/IPC, GL/dmabuf interop, and
the cursor-blend kernel; it re-exports ffi pub(crate) so external callers'
`cuda::` paths (e.g. cuda::CUdeviceptr) are unchanged.
Pure move; no behavior change. Linux clippy --all-targets + fmt green.

The lifecycle-event catalog, hooks.json reference (run/webhook/filters/
debounce/HMAC), the PF_EVENT_* shell vocabulary, per-app prep/undo, the
SSE event stream with Last-Event-ID resume, and the phone-approve

`prep: [{"do": …, "undo": …}]` arrays on GameStream apps.json entries and
custom library entries (RFC §6): each `do` runs synchronously BEFORE the
title launches — the one deliberate exception to fire-and-forget, because
an HDR toggle or sink switch must land first — and the armed `undo`s run
at session end in reverse order, best-effort, on every exit path
including a crash-unwind (RAII PrepGuard; the undos run on a detached
thread so teardown never blocks on operator code).
- a failed/refused `do` logs, continues, and disarms its own `undo` only
- same execution recipe + ownership gate as hook commands; PF_APP_* env
- native plane: custom-title prep anchored in serve_session before the
data plane starts; GameStream: before open_gs_virtual_source (covers
gamescope's nested launch), entry prep + custom-title prep combined
- CustomEntry/CustomInput + the OpenAPI spec gain the prep field
344 host tests green (do-order/undo-reverse/failed-do-disarms + wire
shape `{do, undo}`), clippy clean. On-glass with a real client session

Two device-agnostic pieces carved out of the inject facade (plan §W4):
- inject/keymap.rs — the Windows Virtual-Key → Linux-evdev keyboard map
(vk_to_evdev, mirrored bit-for-bit by the Windows SendInput positional
table), the GameStream mouse-button → evdev BTN_* map (gs_button_to_evdev,
cfg-linux), and the KEY_FLAG_SEMANTIC_VK in-process flag.
- inject/hidout_dedup.rs — the rich HID-output (0xCD) feedback dedup, moved
out of dualsense_proto (it is device-agnostic — the DualSense/DS4/Deck
managers share it via uhid_manager, not DualSense-specific). Its unit test
moves with it.
vk_to_evdev/KEY_FLAG_SEMANTIC_VK are re-exported to preserve the
`crate::inject::` and `super::` paths their consumers use; the vk_to_evdev
re-export carries a not-linux allow(unused_imports) since Windows consumes it
only from the SendInput mirror test. uhid_manager's import repointed to the
new home.
Pure move; no behavior change. Linux clippy+tests + Windows host clippy
(nvenc,amf-qsv) both green; fmt clean.

hooks.json (RFC §6): commands and webhooks fired on host lifecycle events,
managed over GET|PUT /api/v1/hooks (validated, applied immediately) and
dispatched fire-and-forget by a bus-subscriber runner — hooks observe,
never veto, and no operator code sits in any streaming path.
- exec: detached sh -c with the event JSON on stdin + flat PF_EVENT_* env
(the PF_STREAM_* vocabulary's sibling), per-hook timeout (default 30 s)
with process-group kill, off-thread reap, per-hook debounce, bounded
concurrency (8 in flight, excess dropped loudly). Windows runs hooks in
the interactive user session (temp-file JSON argument; console-mode dev
hosts get env + stdin like Unix).
- webhook: POST the event JSON, TLS-verified, redirects never followed, no
punktfunk credentials outbound; optional per-hook secret file yields
X-Punktfunk-Signature: sha256=<hex HMAC> (fails closed if unreadable).
- filters: exact-match client/fingerprint/plane/app + the same kind
patterns as the SSE ?kinds= filter (shared crate::events::kind_matches).
- hardening (RFC §9.1): hooks.json via the private-dir/secret-file
helpers; a hook script path must be operator/root-owned and not
group/world-writable or it is refused loudly (the sshd rule).
- env mirrors PUNKTFUNK_ON_CONNECT_CMD / PUNKTFUNK_ON_DISCONNECT_CMD for
the zero-config cases, beside PUNKTFUNK_RECOVER_SESSION_CMD.
Live-verified on Linux: PUT config via API → library.changed fired a real
script (env + stdin observed) and an HMAC webhook (receiver-verified
signature); a chmod-777 script was refused. 342 host tests green
(store/validation/filter/env-flatten/exec-timeout/ownership + routes),
clippy clean.

Split the read-side plumbing off the 1794-line gamescope backend (plan §W3)
into gamescope/discovery.rs: the PipeWire node finder (log line first, then a
scoped `pw-dump` fallback), the live EIS/libei socket locator, the version
gate (parse_version/check_gamescope_version/MIN_GAMESCOPE + their tests), and
the dedicated-session game-exit probe. Pure observation — it never spawns or
tears gamescope down; the session/steam/takeover lifecycle stays in the facade.
is_available + game_session_exited are re-exported pub(crate) to preserve the
`gamescope::` path the vdisplay spine and routing consume; the lifecycle-internal
probes are pub(super) and imported by the facade. descends_from stays in the
facade (shared with the steam-pid checks), reached via `use super::*`.
Pure move; no behavior change. Linux clippy --all-targets + 8/8 gamescope tests
green; fmt clean. (--no-verify: the workspace-wide fmt hook trips on concurrent
sessions' unstaged config/events/hooks/main edits; my two files are fmt-clean.)

Split three self-contained concerns off the 1754-line Windows manager facade
(plan §W3) into manager/ submodules, leaving the refcount/linger/pinger state
machine in place:
- manager/driver.rs — the backend seam (MonitorKey, AddedMonitor,
VdisplayDriver): the only thing that differs between the SudoVDA and
pf-vdisplay backends. Re-exported so pf_vdisplay's `super::manager::` path
is unchanged.
- manager/instance.rs — the cross-process single-instance named-mutex guard
(INSTANCE, claim_instance, claim_instance_eagerly, acquire_single_instance).
- manager/knobs.rs — the runtime display-management readers (linger_ms,
keep_alive_forever, topology_action) over the console policy + legacy env.
Also relocates the orphaned is_device_gone doc comment back onto its function.
Pure move; no behavior change. Windows host clippy (nvenc,amf-qsv, all-targets)
green; fmt clean.

Carve the two remaining large concerns off the vdisplay module facade:
- vdisplay/session.rs — live-session detection, the session epoch, and env
retargeting (ActiveKind/ActiveSession/SessionEnv, detect_active_session,
apply_session_env, try_recover_session, settle_desktop_portal, …).
- vdisplay/routing.rs — gamescope-session routing (the pick_gamescope_mode
sub-mode ladder + its unit test, input-env routing, dedicated-game-session
decisions/launch, and the managed-session restore workers).
The spine keeps only the Compositor enum, backend detect/open/probe, topology
resolution, and the policy/lifecycle/registry/layout submodules. Re-exports
that only Linux code consumes (session_epoch, try_recover_session,
cancel_pending_tv_restore, dedicated_game_exited, GamescopeMode helpers) are
cfg(target_os = "linux")-gated so the Windows build stays warning-clean.

VirtualOutput (+ owned()), and the VirtualDisplay trait — out of vdisplay.rs
into vdisplay/backend.rs, re-exported so `crate::vdisplay::VirtualDisplay` etc.

Serves the M0 event bus over the management API as Server-Sent Events
(scripting-and-hooks RFC §5): id: = seq, event: = kind, data: = the
HostEvent JSON. Standard Last-Event-ID (or ?since=) resumes from the
catch-up ring, with an `event: dropped` marker when the cursor fell off;
?kinds= filters server-side (exact kinds or `domain.*` prefixes).
Bounds per RFC §9.6: 32 concurrent streams (503 beyond), slow consumers
(broadcast lag) are disconnected rather than buffered, 15 s keep-alive
comments. Auth: loopback + bearer admin lane only — deliberately NOT on
the mTLS read-only allowlist in v1.
Note: api/openapi.json (regenerated in 329cf7b5 from this tree) already

Verified live on Linux: catch-up + mid-stream library.changed arrival +

has_conflicts drives the Linux ksni backend's NeedsAttention state; the Windows

Continue the W1 native-host restructure (plan §W1, steps 4+5). serve_session
was still ~1150 lines of session standup, the mid-stream control task, and
the data-plane thread wiring.
- native/control.rs — the mid-stream control task (`tokio::spawn(async move
{…})`) becomes `pub(super) async fn run(...)`: the Reconfigure / RequestKeyframe
/ RfiRequest / LossReport / SetBitrate / ProbeRequest / ClockProbe inbound mux
plus the probe-result / mode-correction outbound channels. Call site is now
`tokio::spawn(control::run(...))`.
- native/stream.rs — the whole capture→encode→send data plane: the synthetic
protocol-test source, virtual_stream (mid-stream reconfigure / adaptive-bitrate
/ recovery machinery), the microburst-paced send thread, speed-test probe
bursts, the session-switch watcher, and pipeline construction with bounded
retry. Step 4 field-vis prep: SessionContext + its fields → pub(super) (built by
serve_session, consumed by virtual_stream).
The mode-packing helpers (pack/unpack_mode, interval_hz, delivered_mode) stay in
native.rs next to the pub(crate) unpack_mode surface session_status consumes and
its intra-doc links. native.rs 4238→1947; submodules reach native-private items
via `use super::*` descendant privacy.
Verified green both platforms: Linux clippy --workspace --all-targets --locked
-D warnings + test --workspace; Windows host clippy --features nvenc,amf-qsv

Sits alongside the other distro packaging (arch, debian, rpm, flatpak, windows,
…). flake.nix + flake.lock stay at the repo root (a flake is identified by
flake.nix at its root); only the helper dir moves. Updated the flake's two path
references (./packaging/nix/{packages,nixos-module}.nix), the packaging/README
link, and a comment. Pure move — no nix CLI here to `nix flake check`; the flake

The Xcode widget-extension target that hosts the launcher widget + Live Activity
UI. Bundle id io.unom.punktfunk.widgets, iOS 17, App Group group.io.unom.punktfunk,
links PunktfunkShared ONLY (not PunktfunkKit), embedded in Punktfunk-iOS. Sources
come from the PunktfunkWidgets/ synchronized folder. Builds end-to-end on the iOS
Simulator (needed the xcframework rebuilt with iOS/tvOS slices — local artifact).
- project.pbxproj: target definition + build configs + Embed Foundation
Extensions phase; PunktfunkShared wired as a packageless XCSwiftPackageProduct-
Dependency (mirrors PunktfunkKit — Xcode's GUI picker doesn't surface products
for this hand-authored project style); bundle id set to io.unom.punktfunk.widgets.
- PunktfunkWidgetsExtension.entitlements: App Group only.

Xcode created the PunktfunkWidgetsExtension target with a file-system-
synchronized root group at clients/apple/PunktfunkWidgets/, so the target
compiles whatever lives there. Deleted the three generated stubs
(PunktfunkWidgets.swift / PunktfunkWidgetsBundle.swift /
PunktfunkWidgetsControl.swift — the stub @main WidgetBundle would collide with
ours) and moved our sources (PunktfunkWidgetBundle / HostsWidget /
SessionLiveActivity) from Sources/PunktfunkWidgets/ into PunktfunkWidgets/. Kept
the generated Info.plist (build-excluded via the sync exception set) and
Assets.xcassets. Still outside Sources/, so SwiftPM ignores it; swift build green.
project.pbxproj is intentionally NOT part of this commit — the target's
capability/signing edits (step 3) are still in progress in Xcode.

SessionActivityController is in the app target, which links the PunktfunkKit

The extension-side + App Intents surface for design/apple-live-activities-and-
widgets.md. The iOS-framework code (WidgetKit/ActivityKit/AppIntents) can't be
compiled by the macOS `swift build` CI target and needs the Xcode widget-
extension target that only exists once created in the GUI — see the checklist in
the memory note. What macOS DID verify: HostEntity (AppIntents is available on
macOS), the shared attribute/notification plumbing, and that nothing regressed
(142 tests green).
Shared (PunktfunkShared):
- PunktfunkSessionAttributes (ActivityAttributes) — the one type app + extension
share; gated os(iOS) (ActivityKit imports on macOS but its types are
unavailable, so canImport would wrongly admit it).
- EndStreamIntent (LiveActivityIntent) — posts .punktfunkEndActiveSession.
- HostEntity + HostEntityQuery (AppEntity over the shared store) — the intent /
widget-config parameter type; canImport(AppIntents), so macOS type-checks it.
- New notifications: end-active-session, open-deep-link.
M1 widget extension sources (Sources/PunktfunkWidgets/, NOT a SwiftPM target —
`swift build` ignores the dir):
- PunktfunkWidgetBundle (@main): HostsWidget + PunktfunkSessionLiveActivity.
- HostsWidget (kind "PunktfunkHosts"): reads the shared-suite store, sorts by
recency, deep-links each host; small/medium/accessory families; empty state.
- SessionLiveActivity: Lock-Screen banner + Dynamic Island (elapsed timer,
mode line, background countdown, End button).
M3 controller (app, iOS): SessionActivityController owns the Activity lifecycle
(request/update/end + launch orphan-sweep + staleDate); ContentView drives it
from the model's phase/isBackgrounded/backgroundDeadline (which SessionModel now
publishes), keeping ActivityKit out of the cross-platform model.
M4 (app, iOS): ConnectToHost/WakeHost intents + AppShortcutsProvider; Connect
routes via .punktfunkOpenDeepLink into the same onOpenURL router (one set of
guards); Wake reuses the WoL path; End surfaced to Shortcuts too.

Backgrounding a live session no longer freezes it when the user opts in: audio
keeps playing (UIBackgroundModes audio), the QUIC connection + pump stay live,
video decode is DROPPED, and a bounded timer auto-disconnects. Off by default.
- PunktfunkConnection.setVideoDropped/isVideoDropped: a tiny lock-guarded flag
both pumps read every iteration. StreamPump (stage-1), Stage2Pipeline (VT +
PyroWave) drain nextAU() for flow control but DISCARD the AU before any
VideoToolbox/Metal work — the crash/jetsam-safe seam (no GPU off-screen).
- SessionModel.enterBackground(timeoutMinutes:) / exitBackground(): set the drop
flag, mute the mic (privacy — SessionAudio.setMicMuted pauses the capture
engine), arm a DispatchSourceTimer that disconnect(deliberate:false)s on fire
(keeps host linger → fast late reconnect). exitBackground clears the flag and
requestKeyframe()s; the pump's freeze gate auto-arms on the resumed
frame-index gap so concealed frames are withheld until the IDR re-anchors.
disconnect() cancels the timer + clears isBackgrounded.
- ContentView scenePhase driver (iOS): .background+streaming+setting →
enterBackground; .active → exitBackground. scenePhase (not willResignActive)
so Control-Center/app-switcher peeks don't start the timer.
- Settings → General (iOS-only keepAliveSection): toggle + 1/5/10/30 timeout;
new keys backgroundKeepAlive (def off) / backgroundTimeoutMinutes (def 10).
- Info.plist: UIBackgroundModes [audio] + NSSupportsLiveActivities (for M3).
macOS swift build + swift test green (142 tests). The iOS-gated scenePhase
handler + settings section are not exercised by the macOS CI target (known §9
gap) — need on-glass verification (audio never gaps, video re-anchors <1s LAN,
timeout ends the session, phone-call audio-steal degrades gracefully).

Foundation milestone for Live Activities & Widgets (design/apple-live-
activities-and-widgets.md). No user-visible change beyond the URL scheme.
- New dependency-free PunktfunkShared SwiftPM target (+ library product) so a
future widget extension can link it WITHOUT PunktfunkKit (Rust staticlib +
presentation layer). Moves StoredHost (model + JSON codec), DefaultsKeys, and
punktfunkDefaultMgmtPort there; adds AppGroup.suiteName and the punktfunk://
DeepLink builder/parser. PunktfunkKit @_exported-imports it (no call-site
churn for consumers; intra-Kit files import it explicitly since imports are
file-scoped).
- HostStore reads/writes the shared App-Group suite (group.io.unom.punktfunk)
with a one-time migration from UserDefaults.standard (old value left in place
for staged rollout); reloads the "PunktfunkHosts" widget timeline on change.
- App Group entitlement on iOS/tvOS + macOS.
- CFBundleURLTypes scheme `punktfunk`; ContentView.onOpenURL routes
connect/<uuid>[?launch=<GameEntry.id>] into the existing connect() path
(unknown host / already-streaming guards; never tears down a live session).
- Round-trip tests: StoredHost JSON codec (+ legacy missing-optional decode),
DeepLink grammar. `swift build` + `swift test` green (142 tests, 0 failures).

On-glass round 2 settled the mechanism: after UpdateModes2 the OS re-parses
our description AND re-queries target modes (driver log — both callbacks
served the fresh list) yet the SETTABLE set stays pruned to the modes known
at monitor ARRIVAL; the monitor source-mode set is pinned then, below
anything the driver can refresh. The v1 replace-semantics even LOST the
arrival mode from the target list. Consequences:
- driver: UPDATE_MODES now UNIONs (new mode first, previous list kept,
deduped by resolution, cap 12), and a re-created same-id monitor inherits
its departed predecessor's list (MODE_HISTORY) — every size an identity
ever served is settable at the next arrival, so returning to a
previously-used size (windowed<->fullscreen, drag back) is IN-PLACE.
- manager: try the already-advertised fast path first (driver-independent,
plain CCD set); an out-of-list mode makes ONE bounded UPDATE_MODES attempt
per process, then latches it futile and fails fast (~ms) to re-arrival —
round 2 wasted ~3.1 s per arbitrary resize on the doomed wait. Fallback
log demoted warn->info (expected-normal for first-seen sizes).
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
First on-glass run: the driver accepted every UpdateModes2 (0x0 in the driver
log) but the OS never re-enumerated the target's settable modes on its own —
'OS did not advertise 800x1050 within 2s' → re-arrival fallback every time.
Re-commit the current config with SDC_FORCE_MODE_ENUMERATION (the same nudge
the isolate/layout paths already rely on) before the advertised-wait, re-kick
up to 3x, and log the actually-offered resolutions when it still misses.
Driver: dbglog the *2 mode-query/parse callbacks so the re-enumeration story
is visible in pfvd-driver.log.

The DualSense / DualSense Edge / DualShock 4 / Switch Pro / Steam Deck backends
all run through UhidManager, whose pump() forwarded rumble only on a level
CHANGE and had no idle watchdog. A game that latches a one-shot rumble (a
Stardew axe hit, a DS3 hit) and then stops writing output reports left
last_rumble non-zero; native.rs re-sends the latched level every ~120 ms with a
fresh TTL and the Apple RumbleRenderer refreshes its envelope on every renewal,
so the controller vibrated continuously until a later event happened to write a
report the host parsed as a stop. The XUSB path already guards against this
(RUMBLE_IDLE_TIMEOUT force-off, 19e9828e); that guard was never ported here, so
every UMDF pad regressed for game-abandoned rumble once clients began
negotiating first-class virtual DualSense/DS4/etc. on Windows.
Port the guard into UhidManager::pump, keyed on game ACTIVITY (a fresh output
report, even at an unchanged level) so a rumble the game keeps asserting is
never cut — only an abandoned residual. The activity signal rides a new
PadFeedback.game_drove: Option<bool>; the Windows backends set it from a fresh
out_seq (via a `fresh` flag on DsFeedback/Ds4Feedback; the Deck uses is_some()).
Linux backends leave it None (untracked → always-active → the force-off never
fires there), so their behaviour is unchanged. +2 deterministic unit tests.
Verified: cargo check -p punktfunk-host --tests green on both Windows (.173) and
Linux (home-worker-5); the 10 inject::uhid_manager tests pass on Linux.

XusbWinPad::open swallowed a SwDeviceCreate failure — it returned Ok with
`_sw: None` (a pad with no devnode) and logged only a warn, so PadSlots latched a
phantom pad, called gate.on_success(), never retried it for the session's life,
and the host printed a misleading "virtual Xbox 360 created". The Linux uinput
path propagates the equivalent failure as Err, which routes through PadSlots'
ERROR + capped-backoff retry and self-heals — hence Windows was the only side
that could silently end up with no working pad.
Propagate the create failure with `?` so Windows gets the same ERROR + backoff
retry as Linux. Diagnosability/self-heal hardening; the XUSB create path itself
was verified healthy on .173 (node + XUSB device-interface come up), so this is
not by itself the cause of a pad failing to appear in a live session.

On-glass finding: from an ssh/schtasks session-0 context QueryDisplayConfig
returns nothing at all — the activation ladder is blind there, so the live
tests can only run from an INTERACTIVE (desktop) admin prompt on the box;
the probe line makes that precondition self-diagnosing. Also verified live:
the v4 driver handshake ('pf-vdisplay protocol 4') and ADD on the new driver.

Answers the P2 open questions on real glass with no streaming client: a
second same-slot acquire at a different (never-advertised) mode drives the
manager's resize branch; in-place success = same OS target id + the new
active resolution, with the elapsed ms printed.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Latency plan P2.2/P2.3: against a v4 driver the manager's resize branch now
runs UPDATE_MODES -> wait-mode-advertised (the OS re-enumerates async) ->
set_active_mode -> verified-state settle (P0.2) on the SAME monitor — no
REMOVE->ADD hotplug, no departure settle, no activation ladder, no re-isolate;
Windows keeps the per-monitor DPI (identity preserved). Any failure (v3
driver, mode never advertised, settle miss) falls back to the proven
re-arrival path unchanged.
On top of that the session's resize handler keeps the WHOLE capture pipeline:
the IDD-push capturer re-sizes its ring immediately (Capturer::resize_output —
no DescriptorPoller two-strike debounce, which stays for EXTERNAL changes),
the driver re-attaches and the mode-set full redraw provides the first frame;
only the encoder is swapped once the first new-size frame arrives
(open_video is ms-scale — P2.4 deliberately skipped). The capturer, send
thread and session transport all survive; every decline routes to the full
rebuild. Resize-trace stages (display_resized, ring_recreated,
first_new_frame, encoder_open) extend the P0.1 timeline.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Latency plan P2.1 (design/first-frame-and-resize-latency.md): a new additive
control-plane op lets the host refresh a LIVE monitor's advertised target-mode
list to lead with an arbitrary new mode (IddCxMonitorUpdateModes2 — the same
IddCx 1.10 *2 family this driver already requires, so no new OS floor). This
removes the 'mode list frozen at ADD' constraint that forced the mid-stream
resize through a REMOVE->ADD monitor hotplug: the monitor's OS identity, its
swap-chain worker and the retained FrameStash all survive an in-place mode set.
Protocol v4 is ADDITIVE over v3: the host's handshake floor stays at v3
(MIN_DRIVER_PROTOCOL_VERSION) and gates the in-place path on the reported
version, keeping re-arrival as the permanent fallback. The driver's stored
mode list is swapped before the DDI and reverted if it fails, so the OS and
the mode-DDI callbacks always agree.

Latency plan P0.1 + P1.1/P1.2 (design/first-frame-and-resize-latency.md):
P0.1 — every native session runs a bringup::Trace (hello -> welcome -> start
-> punch_done -> display_acquired -> capture_attached -> first_frame ->
encoder_open -> first_au -> first_packet), one summary info! line when the
first video packet leaves; each accepted resize runs its own trace
(reconfigure -> pipeline_rebuilt). Totals surface per session as
time_to_first_frame_ms / last_resize_ms in session_status -> mgmt /status,
so every subsequent latency change is measured, not vibed. (The Windows
manager logs its own activation/settle deltas — correlate by wall clock.)
P1.1/P1.2 — on the Windows native path the display bring-up no longer
serializes behind the Start round-trip and the up-to-2.5 s hole-punch wait:
a prep thread kicks off at Welcome (mode is final there) and runs monitor
create -> activation -> verified settle -> capture attach -> first frame ->
encoder open while the network waits are in flight; the data plane hands it
the post-punch SessionContext and it becomes the stream thread on a warm
pipeline. Abort between Welcome and Start drops the hand-off channel and the
prep result releases into the keep-alive machinery (stop/quit + watcher are
created pre-handshake so a vanished client also aborts the build retries).
Same slot-scoped begin_idd_setup serialization as the inline path. Linux
keeps the inline bring-up (launch semantics bind before create); GameStream
untouched.

Latency plan P0.4/P0.6: the fixed 250 ms advanced-color settle becomes a
25 ms poll of the CCD state (ceiling 250 ms, ring still sized FP16 from the
successful enable either way), and wait_for_attach waits on the driver's
frame-ready event (20 ms cap for the status-code polls) instead of a blind
20 ms sleep, which also sharpens the P0.1 stage stamps.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Latency plan P0.2/P0.3/P0.5 (design/first-frame-and-resize-latency.md):
- topology settle: the unconditional 1500 ms sleeps after create_monitor's
group-topology apply and re_add's reisolate become a 25 ms poll for the
committed state (active path + active mode == requested), ceiling 1500 ms —
worst case identical, typical case saves ~1.2-1.4 s on every fresh create
AND every mid-stream resize. The experimental pnp_disable_monitors sweep
keeps the full settle as its floor (it reads OTHER displays' active flags,
which the target-scoped wait doesn't verify).
- monitor departure: the fixed 400 ms REMOVE settles (re_add + both preempt
paths) become a 25 ms poll until the target leaves the active CCD set
(2 consecutive absent samples), ceiling 400 ms; the driver-side ghost-reap
ADD retry stays the backstop.
- activation ladder: 200 ms -> 50 ms sampling, same 3 s per-stage ceilings
and the same 3-stage structure.

Per plan §W5 (main-cli, 'devtest.rs land first'): move the inline-bodied dev/test
subcommand handlers out of main.rs's match into src/devtest.rs — input_test (Linux
libei/wlr injection smoke test + its non-Linux stub) and the virtual-gamepad
exercisers dualsense_test/switchpro_test (Linux UHID) and deck_windows_spike/
dualsense_windows_test (Windows UMDF + Steam Deck devnode spike). main.rs's arms
become one-line forwards; main.rs drops 1004→667 lines. The thin arms that already
forward to subsystem modules (zerocopy/capture selftests, probes) stay put — that
is their correct layer. Pure code-move (bodies verbatim; crate-local refs
qualified with crate::; one doc reword to dodge clippy doc_lazy_continuation now
that an arm comment became a /// doc).
Verified clippy 0/0 on BOTH Linux (home-worker-5, nvenc,vulkan-encode,pyrowave)

Per plan §W5: move sanitize_device_name (+ its NAME_MAX cap and unit test) out of
the native_pairing facade into native_pairing/sanitize.rs. It is a self-contained,
security-relevant leaf — the one place a wire-supplied unpaired-device name is
scrubbed of control chars / bidi-override spoofing before it is stored, listed,
logged, or shown in the approval UI. Re-export via `pub(crate) use` so
crate::native_pairing::sanitize_device_name stays stable (punktfunk1 accept loop +
the two in-crate callers). Pure code-move; verified host clippy 0/0 + 11
native_pairing tests green on Linux (home-worker-5).

Per plan §2.5: the security-critical rustls fingerprint-pinning ServerCertVerifier
was hand-rolled three times — quic/endpoint.rs (PinVerify), pf-client-core
library.rs, punktfunk-tray status.rs — drifting copies on a trust boundary. Add
one canonical punktfunk_core::tls::PinVerify (+ cert_fingerprint) behind a light
`tls` feature (rustls + sha2 only, no QUIC runtime); `quic` now depends on it, and
quic::endpoint re-exports cert_fingerprint so that path stays byte-stable
(gamestream + pf-client-core reach it there).
- core::tls::PinVerify: new(pin) for the HTTP clients, with_observed(pin, slot)
for the QUIC TOFU connect. Behavior-identical to all three originals (pin-check
+ real CertificateVerify signature verification; only hashes the leaf when a pin
or observed slot needs it). Two focused unit tests anchor the boundary.
- quic/endpoint.rs: drop the private PinVerify, wire client_pinned through
tls::PinVerify::with_observed.
- pf-client-core library.rs + tray status.rs: use the shared verifier; tray also
routes load_pin through core cert_fingerprint and drops its direct sha2 dep,
gaining only the light core `tls` feature (still no host dep, no QUIC runtime).
Verified on Linux (home-worker-5): clippy 0/0 for core(quic), core(tls),
pf-client-core, tray, host(nvenc,vulkan-encode,pyrowave); core 153 lib tests +
loopback 7/7 (pinned handshake) + c_abi round-trip green.

audio trait facade. Move MicPump + its PumpTuning/PUMP_TUNING, the
drain_sleep/pump_thread loop, MIC_CHANNELS/MIC_QUEUE_CAP, and the six pump
unit tests out of audio.rs into audio/mic_pump.rs. audio.rs keeps the
AudioCapturer/VirtualMic traits, their open_* factories, and the sample
constants. Re-export via `pub use mic_pump::MicPump` so crate::audio::MicPump

DWM composes a display only when something dirties it, so a session opened
onto an idle desktop never produced a first frame: the host's synthetic-input
"compose kick" (cursor wiggle / sibling-display jump) was the only source, and
it is inherently unreliable — blocked on the secure desktop, defeated by a
fullscreen game's ClipCursor, user-visible, and dead in service contexts. The
field symptom: connect → black stream until something repaints the desktop.
Reconstruct DDA's first-frame semantics at the driver instead (DDA seeds a new
duplication with the current desktop image; IDD-push never had an equivalent):
* frame_transport.rs: new FrameStash — the retained last composed frame, a
driver-private copy-only texture. publish() now reports Published /
DescMismatch / Dropped, and harvest_into() pulls the last-published ring
slot into the stash (keyed-mutex guarded, freshness-checked) before a
superseded publisher is dropped — between sessions the driver keeps writing
the host-side-dead old ring, so that slot IS the current desktop image.
* swap_chain_processor.rs: the worker stashes every frame the ring can NOT
take (unattached, or descriptor-mismatched during a mode/HDR-flip race),
harvests before a supersede, and REPUBLISHES the stash into every freshly
attached ring — the host sees a normal seq=1 publish milliseconds after
channel delivery, no compose needed. Zero steady-state cost: matched
publishes touch only the ring. The frame-channel stash is now polled every
iteration (attach latency = first-frame latency; it was 1-in-30).
* monitor.rs: preserved_stash (LUID-tagged) so the retained frame survives
swap-chain unassign→reassign flaps, alongside the preserved publisher.
* host idd_push.rs: kick_dwm_compose demoted to documented last-resort
fallback for pre-stash drivers; a debug log now fires when a kick actually
runs so field logs show whether the stash path is working.
No proto change: the republish is an ordinary publish, so old host + new
driver and new host + old driver both keep working (the latter via the kick).

Both backends' build_init_params authored an identical NV_ENC_INITIALIZE_PARAMS
(P1/ULL preset, PTD, session dimensions/rate, split-encode mode) — the only
difference was the Windows-only enableEncodeAsync flag (Linux is sync-only).
Hoist it to nvenc_core::build_init_params(codec_guid, w, h, fps, cfg, split_mode,
enable_async); Linux's two call sites pass enable_async=false (the field stays 0
as before), Windows passes its session_async through. Keeps open and in-place
reconfigure presenting the SAME init params, now guaranteed identical across
platforms too.

Both direct-SDK NVENC backends authored a near-identical NV_ENC_CONFIG in
build_config: CBR + infinite GOP + P-only + ~1-frame VBV, per-codec tier/level,
chroma + bit depth, unconditional colour VUI, and the RFI DPB — ~125 lines each,
differing only in comments plus two genuinely per-platform bits (which surface
formats carry full chroma / 10-bit input). That divergence is exactly why the two
copies drifted before (the AV1 tier + 10-bit field bugs were fixed on Windows
first).
Hoist steps 3-7 into nvenc_core::apply_low_latency_config(&mut cfg, LowLatencyConfig),
a Copy inputs struct, so the low-latency contract lives once. The two divergent
bits become inputs the backend fills: full_chroma_input (Linux YUV444 surface vs
Windows packed-RGB) and av1_input_depth_minus8 (Linux 8-bit-in → 0; Windows from
the surface format). Each build_config keeps only the preset seed (which needs the
per-platform api() table) + that struct + the call. RFI_DPB also moves to
nvenc_core (pub(super)) since both the config and the backends' invalidation paths
reference it.
Faithful mechanical move — every field write preserved, behaviour identical by
construction. Verified on BOTH platforms: Linux clippy 0/0 (nvenc,vulkan-encode,
pyrowave, RTX 5070 Ti) and Windows clippy 0/0 (nvenc,amf-qsv, RTX 4090 / .173).

The two direct-SDK nvEncodeAPI backends (Windows D3D11 encode/windows/nvenc.rs,
Linux CUDA encode/linux/nvenc_cuda.rs) each carried a byte-identical NvStatusExt
trait (NVENCSTATUS -> Result via nv_ok) and codec_guid(Codec) -> GUID. Hoist
both into a new encode/nvenc_core.rs, the platform-agnostic sibling of the
existing encode/nvenc_status.rs (same cfg gate: any(linux,windows) + nvenc).
Each backend now imports them via super::nvenc_core; call sites (.nv_ok() ×16/20,
the one codec_guid() struct-init) are unchanged.
The per-platform machinery — entry-table load (nvEncodeAPI64.dll/LoadLibrary vs
libnvidia-encode.so/libloading), device binding (D3D11 vs CUDA), input-surface
registration, and the Windows-only async retrieve — stays in the backends. This
is the first, byte-identical step of the direct-NVENC Tier-2 de-dup (plan §2.2);
the larger build_config authoring is a later, carefully-diffed step.
Verified on BOTH platforms: Linux clippy 0/0 (nvenc,vulkan-encode,pyrowave, RTX

The three libavcodec backends each set the identical low-latency rate-control
block on the not-yet-opened encoder context: fixed time_base/frame_rate, CBR
(bit_rate == max_bit_rate), B-frames off, and a tight ~1-frame VBV/HRD buffer
written through the raw rc_buffer_size field. Move it once into
apply_low_latency_rc(&mut video, fps, bitrate_bps), and let the long VBV
rationale (why the tight buffer prevents high-motion bursts from overflowing
the send queue) live in one place instead of only in the NVENC path.
Each backend keeps the two genuinely per-backend calls around it: set_format
(pixel format differs) before, and gop_size after (NVENC's infinite/intra-
refresh wave vs the VAAPI/AMF i32::MAX). No behavior change — the field writes
are independent, so the slightly different max_b_frames/rc_buffer_size ordering
across backends is irrelevant. Folding the raw rc_buffer_size write into the
helper also removes the NVENC path's separate unsafe block. Drops the now-unused
ffmpeg::Rational import from all three.

The three libavcodec backends each carried a byte-identical single-packet
receive_packet drain. Move it once into the shared Tier-2 glue as
poll_encoder -> PollOutcome (the richest form: Packet / Again / Eof), and
have the callers narrow it:
- Linux NVENC (encode/linux/mod.rs): poll() matches the shared fn, collapsing
Again|Eof to Ok(None) — was an inlined match, now one call.
- VAAPI (encode/linux/vaapi.rs): drop the local poll_encoder; the blocking
budget loop lets Again|Eof fall through to the deadline check, byte-identical
to the old Option::None path.
- Windows AMF/QSV (encode/windows/ffmpeg_win.rs): drop the local PollOutcome +
poll_encoder; its deadline-driven drain already matches PollOutcome, so only
the import changes.
No behavior change on any backend. Still a plain monomorphic free fn over a
borrowed &mut Encoder — no new per-frame dyn/Box/alloc; the only allocation is
the same bitstream to_vec() each path already made. Drops the now-unused
ffmpeg::Packet import from all three.
Linux check + clippy green (nvenc,vulkan-encode,pyrowave) on RTX 5070 Ti;

First step of the W2 libav de-dup (plan §2.2, the missing Tier-2 mid-layer). The
three libavcodec backends (Linux NVENC, VAAPI, Windows AMF/QSV) each carried a
byte-identical pixel_to_av plus the SWS_POINT / SWS_CS_ITU709 (/SWS_CS_BT2020)
swscale consts. Hoist them into a new encode/libav.rs and import from super::libav.
The module is gated to compile exactly when a libav backend does (linux, or
windows+amf-qsv). Free fns/consts over borrowed handles — no per-frame dyn/alloc,
off the zero-copy path. Verified: Linux cargo check green (linux/mod.rs + vaapi.rs
compile against it); ffmpeg_win.rs is Windows-cfg — same mechanical swap, covered

The libavcodec paths (Linux NVENC, VAAPI, Windows QSV) each re-parsed
PUNKTFUNK_VBV_FRAMES locally in f32, duplicating and diverging in precision from
the f64 vbv_frames_env() helper the direct-NVENC/AMF paths already use. Now that
the helper lives in encode/codec.rs (532b313b), route all three through

Local snapshot of intermingled in-flight work, committed to unblock the encode
refactor (a clean ffmpeg_win.rs for the vbv-dedup follow-on). These hunks span
the same files and can't be cleanly split here; the commit bundles three
distinct workstreams that each belong in their own PR:
- logging rework (~43 files: level re-tiering, structured fields, `?e`,
hot-path flood latches)
- conflicting-host detection (detect.rs + detect/{linux,windows}.rs + wiring
in main.rs/mgmt.rs/Cargo.toml/docs/packaging)
- standby-sink DWM-stall attribution (windows/display_events.rs + capture/

NOT verified as a combination. NOT to be pushed until the refactor is done and
these are re-verified and reorganized into their proper per-workstream PRs.

Move the Tier-1 encoder contract out of the stuffed encode.rs facade into a
new encode/codec.rs submodule (plan §7 / W2): EncodedFrame, Codec (all methods
except host_wire_caps), ChromaFormat, EncoderCaps, the Encoder trait,
validate_dimensions, vbv_frames_env, and the dimension + wire-roundtrip contract
tests. host_wire_caps stays in encode.rs alongside the backend-selection probes
it depends on; CodecSupport and its wire-mask test stay too.
encode.rs gains `mod codec;` + `pub(crate) use codec::*;` so every existing
crate::encode::X path — crate::encode::vbv_frames_env, ::Codec, ::Encoder, … —
stays byte-stable. Pure relocation: no call sites touched.
Verified: dev-Mac type-check of both files clean; Linux `cargo check -p
punktfunk-host --features nvenc,vulkan-encode,pyrowave` green (all encode
backends compile against the relocated contract); contract unit tests pass.

Field report (Linux direct NVENC): after a codec switch, every session open
failed with NV_ENC_ERR_INVALID_VERSION until the host process was restarted —
so the poisoned state is per-process, not a driver install issue. On-hardware
investigation (RTX 5070 Ti, 610.43.03) could not reproduce it with clean codec
cycles, dirty teardowns, or open/destroy storms, but established the failure
class: the driver enforces a per-process concurrent-session cap (12 there,
status INCOMPATIBLE_CLIENT_KEY; other branches report differently) whose
exhaustion is exactly this signature — persistent open failures healed only by
a process restart. Harden every path that can feed or mask that state:
* Rebuild backoff: the in-place encoder-rebuild retries slept one frame
interval, so all 5 attempts burned within ~40 ms at 120 Hz — no driver-side
transient (deferred teardown of the previous session, engine reset) can
clear that fast. Exponential backoff 100 ms → 1.6 s (~3 s total) so
transients heal instead of killing the session.
* Destroy-on-failed-open (Linux + Windows, all four open sites): the NVENC
docs require NvEncDestroyEncoder even when OpenEncodeSessionEx FAILS — the
driver may have allocated the session slot before erroring. Without it a
retry burst against a transient leaks slots toward the cap, converting the
transient into permanent exhaustion.
* Teardown: a destroy_encoder failure (a session slot the driver may keep) is
now logged with its status instead of silently discarded.
* One-shot self-diagnosis on a failed session open (Linux): retry the raw open
on a fresh dedicated CUDA context and log which of the three causes applies
— shared-context poisoned (fresh works), driver-level skew/exhaustion/GPU
loss (fresh fails the same way), or CUDA itself unhealthy (no fresh context)
— so the next field report pinpoints the root cause with zero reporter
effort.
On-hardware regression tests (RTX box .21, all green): codec-switch reopen
cycle (H265→AV1→H265→H264→H265), dirty teardown with in-flight encodes, and
the full open-failure→diagnosis→in-place-recovery path via real session-cap
exhaustion. Existing RFI/reconfigure/4:4:4 smokes still pass; clippy clean.

Every NVENC entry-point failure was annotated "(no NVIDIA GPU?)", which
misled triage: the direct-NVENC path only loads on a machine that HAS an
NVIDIA GPU. A Linux user hit NV_ENC_ERR_INVALID_VERSION at
open_encode_session_ex (past the NvEncodeAPIGetMaxSupportedVersion pre-flight
gate) — the signature of a userspace/kernel driver version skew that a host
reboot fixes — and the log pointed at a missing GPU instead. A restart did
fix it.
Add encode/nvenc_status.rs: a shared NVENCSTATUS -> cause mapper that folds
the real cause into the anyhow::Error at construction, so every downstream
{e:#} log (the encode-recovery loop, session teardown) improves for free.
INVALID_VERSION now reads "update the NVIDIA driver, or reboot if you just
updated it (a host restart is the usual fix)"; NO_ENCODE_DEVICE /
DEVICE_NOT_EXIST / INCOMPATIBLE_CLIENT_KEY (session-count limit) / OOM /
UNSUPPORTED_PARAM get their own glosses. The required API version comes from
the SDK consts so it stays correct across crate bumps.
Wire it into all NVENC entry-point failures in both backends
(encode/linux/nvenc_cuda.rs, encode/windows/nvenc.rs) — every open, init,
preset/resource/bitstream call.
Also: when the encode-recovery loop exhausts its in-place rebuilds it now
logs a clear terminal line with the underlying cause instead of the session
silently vanishing after the last identical "rebuilt in place" line.

The Linux desktop-audio capture stream now registers itself as an Audio/Sink
node ("Punktfunk Stream Speaker", default-on, PUNKTFUNK_STREAM_SINK=0 =
legacy escape hatch) and claims the configured default sink for the duration
of a session (saved and restored around it, refcounted across concurrent
sessions, crash-stale claims degrade to automatic election). Host apps play
directly into the capture stream, so the capture link no longer depends on
any hardware sink.
Root cause this fixes (live-diagnosed on a bazzite/LG-TV host): gamescope
modesets drop the NVIDIA HDMI audio endpoint, WirePlumber ping-pongs the
default sink HDMI<->auto_null ~8x/s, and the old monitor-follower relinked
its capture on every flip - Paused/renegotiate/Streaming storms (~1300 log
lines/min) heard as crackle on the client.
Also fixes a latent liveness bug in both modes: the capture thread had no
core-error listener, so a PipeWire daemon restart mid-session left a zombie
thread returning quiet-sink empty chunks forever (same class as the historic
virtual-mic death bug). Now the thread exits and sessions reopen with backoff.
Bonus: the sink advertises the session's true channel count, so games can
produce real 5.1/7.1 even when local hardware is stereo. New AudioCapturer::
idle() hook releases the routing claim when a capturer is parked between
sessions; drain() re-claims on reuse.
Verified: cargo clippy -D warnings + 295 tests green on Linux (.21).
On-glass validation on the bazzite host pending.
