enricobuehler 70b81ac3d7 test(pf-encode): S1c + the D5 confirm — pair flips in place, AUTO really is dead
S1c `nvenc_cuda_split_subframe_pair_reconfigure`: the leg S1a/S1b excluded. Both
pinned sub-frame OFF to isolate the split variable, but a real HEVC arbitration
cannot -- split and sub-frame are mutually unsupported there, so engaging split
means flipping enableSubFrameWrite in the same breath, a second init param and
the one the reconfigure path deliberately pins. RESULT on .21: the PAIR moves in
place, accepted, ZERO IDRs, both directions.

It also pins the invariant that makes this safe to build on: `subframe_chunks` is
latched ONLY in the init path (~line 1625) and is NOT recomputed by
reconfigure_bitrate, so a caller flipping sub-frame in place must clear it too or
supports_chunked_poll keeps reporting true and poll_chunk busy-polls its whole
budget every AU against a numSlices that never advances. The test performs the
correct sequence and asserts the state stays coherent, so WP3 has a worked
example rather than a warning.

`nvenc_cuda_auto_split_with_subframe`: the D5 confirm -- the one claim in the
design's defect list that was only ever inferred. The driver reports no "mode I
actually chose", so it is settled by timing, at 4K where the gap is ~2x.
RESULT: AUTO (env unset) + sub-frame 4904 us/frame, DISABLE + sub-frame 5062,
TWO_FORCED without sub-frame 3464. AUTO sits 158 us from DISABLE and 1440 from
TWO_FORCED ⇒ D5 CONFIRMED: plain AUTO does not split while sub-frame is on, so
the resolver's AUTO fallthrough reads as "let the driver decide" and means
"never split".

⚠ TRAP, hit on this test's first run and now documented in it: the env knob
CANNOT express plain AUTO. `0` is DISABLE and `1` is AUTO_FORCED, and
resolve_split_subframe counts AUTO_FORCED as forced, so passing `1` silently
disarms sub-frame and measures a different configuration entirely -- which
produced a spurious "D5 REFUTED". Plain AUTO is only reachable as the resolver's
fallthrough with the env unset. The leg now asserts sub-frame resolved TRUE, so
the test can no longer answer the wrong question quietly.

Verified on .21: clippy --features nvenc --all-targets -D warnings clean, all 4
spikes green, the normal 54-test suite unaffected, cargo fmt --all --check clean.

enricobuehler 4b57d11dd8 test(pf-encode): S1 spike — splitEncodeMode CAN change in place, no IDR
Two on-hardware spikes answering the gate on the split-encode engagement
program (design/nvenc-split-encode-engagement-implementation-plan.md).

S1a `nvenc_cuda_split_reconfigure_in_place`: can splitEncodeMode change via
nvEncReconfigureEncoder with resetEncoder=0, without an IDR? Our "reconfigure
must present the SAME init params as the open" rule (windows/nvenc.rs:620) is
our own invariant and had never been tested against a driver. It reports rather
than asserts the verdict -- both outcomes are legitimate findings -- and only
asserts what would invalidate the measurement (session live, engines >= 2, the
arms actually differ). Sub-frame is pinned off so the driver can't reject for
the wrong reason (HEVC forced-split and sub-frame are mutually unsupported).

S1b `nvenc_cuda_split_reconfigure_takes_effect`: the other half -- a driver that
accepts the parameter and quietly ignores it looks identical to one that honours
it. Three legs at 4K (fresh DISABLE / fresh TWO_FORCED / DISABLE->TWO in place);
if C tracks B and not A, the switch is real.

RESULT on .21 (RTX 5070 Ti, GB203 Blackwell, driver 610.57.04):
  NV_ENC_CAPS_NUM_ENCODER_ENGINES = 2
  S1a: accepted, ZERO IDRs, both directions.
  S1b: A fresh DISABLE 5054 us/frame, B fresh TWO_FORCED 2453,
       C switched in place 2419 -- |C-B|=34 vs |C-A|=2635. It takes effect,
       and split is a clean ~2x at 4K.

Two limits, both recorded in the test docs rather than the commit only. The
frames come out at 427 B/AU against an 833 KB CBR quota: the driver hands back
zeroed VRAM, so the rotated buffers are identical and rate control skip-codes
everything. So this measures the PIXEL-proportional half of the cost only --
the bits/frame regime the field case lives in is untested here, and the test
prints an explicit INCONCLUSIVE-on-content line when it detects that. And this
is Blackwell 8-bit; the Ada Main10 question is untouched.

Verified on .21: clippy -p pf-encode --features nvenc --all-targets -D warnings
clean, both spikes green, cargo fmt --all --check clean.

A launcher entry (design D4) has no "the game exited" moment to detect, but the lease was
still deciding its lifetime from whatever happened to be true at launch — and the two
outcomes disagree:

  launcher NOT already running   the spawned child stays alive -> `Child` lease
                                 -> quitting the launcher ends the session
  launcher ALREADY running       the command forwards to the live instance and exits
                                 inside SHIM_WINDOW, with no detect signals behind it
                                 -> `Untracked` -> the session persists

Same tile, two lifetimes, chosen by something the user cannot see. Steam is the case that
settles which one is right: Big Picture is a *mode* of an already-running Steam client, not
a process — and on a Deck or SteamOS host Steam is always running — so no process signal can
express "the launcher's window closed". Heroic has the same shape for a different reason
(single-instance Electron: a second invocation forwards and exits).

So a launcher entry is now `LeaseKind::Untracked` unconditionally. The check sits AHEAD of
`nested`/`child`/`spec`, and that ordering is the fix rather than an implementation detail:
a launcher the host just started leaves a live child behind, and tracking that child is
precisely the inconsistency being removed.

`Untracked` already meant the right things downstream, so nothing else had to change: no
watcher thread, `terminate()` is a no-op ("nothing to end" — closing a session must not kill
the user's Steam), and no `GameExited` event, so a client does not bounce back to its library
when the launcher closes.

Threaded as `LaunchTarget::launcher` -> `LeaseRequest::launcher` from the entry's `role`.
Three call sites, one of which was the actual trap: the GameStream path does not build its
lease from a `LaunchTarget` at all, it goes through a `GsApp` intermediate that silently
dropped the field. An operator-typed `apps.json` command has no library entry behind it and
is never a launcher tile, so it passes `false` explicitly.

The test pins BOTH cases from the table above, plus the same request without the flag still
being `Matched` — so the assertions are the flag's doing and not an artifact of the fixture.

Gates: punktfunk-host 439 passed / 0 failed on .21 (+1).

Not covered here: nothing publishes launcher tiles until the plugins are released, so there
was no live exposure to fix — this is the semantics being made deliberate before the first
tile is ever clicked.

The first pass built each palette by rotating ONE colour field's hue, and it
showed: every option was a single tone at several brightnesses, which reads flat
next to any real gradient. A palette is now an ordered ramp of DISTINCT hues.
The 4×4 mesh samples that ramp along the diagonal with a fixed per-cell offset
table, so neighbouring cells land on different parts of it and the colours pool
and swirl instead of banding; the control points' existing drift then moves the
pools around. Violet keeps its explicit sixteen colours, so the default is
untouched.

Twelve of them now, dark first then pale: Violet, Nebula, Abyss, Ember, Moss,
Graphite, then Holo, Sunset, Bloom, Dawn, Mint, Opal. Holo and Sunset are
straight takes on the two reference gradients — foil and poster.

`every_palette_is_multi_tone` measures the hue spread across all sixteen cells
and fails under 45° (20° for Graphite and Opal, which are meant to be
restrained). It caught Ember at 35°, all reds and oranges — the very flatness
this rework exists to remove — and Graphite at 3° despite a comment claiming it
drifted cool to warm. Both were rebuilt until the numbers matched the prose.

The UI follows the palette now, rather than wearing brand violet over whatever
happens to be behind it. Each palette carries an accent and a light flag, and an
Ink derived from those (foreground, accent, on-accent, glass, scrim and its
strength) is published to the whole tree — a thread-local in the console, an
environment value on Apple, a CompositionLocal on Android. Pale palettes flip
the ink: dark text on white frost, with the materials, tray scrims and every
wash that sits under text following suit.

Three things only the renders could have told us:

  - Additive blending blows out over a pale ground. Android's blobs and Apple's
    legacy field composite with Plus/plusLighter, which over near-white
    saturates every blob to white — Holo rendered as a grey wash. Pale palettes
    blend normally.
  - A white scrim at the dark field's strength BLEACHES the gradient. Mixing
    toward black at 0.4 reads as depth; toward white at 0.4 destroys the chroma
    it is drawn over. The scrim now carries a per-palette strength.
  - White glass over a bright field has far less separating it from its backdrop
    than dark glass over a dark one, and needed more body.

Verified: console build + clippy -D warnings + 173 tests, Apple build + 200
tests + an iOS-triple typecheck, Android compile + 62 tests, and eyeball passes
on real renders of both the vivid and the pale ends (console CPU rasters; a new
Roborazzi light-palette scene, which is what exposed the blend-mode bug).

enricobuehler 166e158afe feat(host/library): an xbox launch kind a de-privileged plugin can publish

The xbox scanner resolves each package's PackageFamilyName by enumerating
%ProgramData%\Microsoft\Windows\AppRepository\Packages. Probed on .173 (design doc S1),
that directory is:

  NT AUTHORITY\LocalService   UnauthorizedAccessException   <- the plugin runner
  LocalSystem                 count=348                     <- the host service

So an extracted xbox plugin cannot build an AUMID, and `aumid` — which takes a complete
`<PFN>!<AppId>` — is unpublishable by one.

The design doc offered two fallbacks: entries without `aumid` (they would list but not
launch), or a one-shot elevated PFN resolve at install time. This is neither. The plugin
sends `<Identity>!<AppId>`, both read straight out of MicrosoftGame.config — which IS
readable de-privileged — and the host resolves the publisher hash at LAUNCH time, where it
already owns command construction.

That keeps D1 intact (the plugin supplies a validated value, the host builds the command),
it is the same shape as the `playnite` kind, and resolving late means a package update that
changes the publisher hash cannot leave a stale unlaunchable tile behind — which the
install-time cache would have.

`xbox_pfn` therefore moves from the scan path to the launch path rather than being deleted,
and its doc records the privilege asymmetry so the next reader doesn't re-derive it.

The charset guard is factored out (`aumid_part` / `valid_aumid`) and shared with the `aumid`
kind. On `aumid` it was belt-and-braces — every value was host-derived. On `xbox` it is
load-bearing: the Identity arrives over the wire from a plugin, and it is interpolated into
a `shell:AppsFolder\…` argument. Validated inbound at reconcile too, so a malformed value is
a 400 the plugin author can act on rather than a tile that fails on click.

Gates: punktfunk-host 438 passed / 0 failed on .21, and 55/0 for the library tests on .173
(where these arms actually compile). Both counts +1 for the new guard test.

`windows/pyrowave.rs` raised the process's WDDM scheduling class to HIGH itself, once per
process, at every session open. `pf-frame::dxgi::auto_priority_gate` already owns that policy
for the whole process and runs from `create_device` — the call the Windows capture path always
makes before any PyroWave texture exists. Two owners of one process-wide setting.

The audit filed this as "downgrades REALTIME to HIGH", which undersells it. pf-frame's default
`auto` mode starts at HIGH and then UPGRADES to REALTIME once it has established that is safe —
HAGS off, or HAGS on with VRAM headroom — and leaves a monitor running that drops back when VRAM
tightens, because REALTIME + NVIDIA + HAGS + near-full VRAM is a documented NVENC hang. Opening
a PyroWave session after that upgrade stamped HIGH back over the class AND orphaned the
monitor's decision, losing the ceiling-raise on exactly the GPU-saturated workload PyroWave
exists to survive: it encodes on the shader cores a game saturates, where the measured spike is
~2 ms to 15-18 ms.

Removed rather than reconciled. `PyroWaveEncoder::open` takes no device, so there was nothing
session-specific to preserve, and the surviving owner is strictly better informed — it knows the
adapter, HAGS state and VRAM headroom, none of which this call site had.

The duplicated knob goes with it: `PUNKTFUNK_GPU_PRIORITY` is retired in favour of
`PUNKTFUNK_GPU_PRIORITY_CLASS` (`off|normal|high|realtime|auto`, default `auto`), which is a
superset — the removed knob could not express the auto gate at all. No other reference to it
exists in the tree.

Verified 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 —
7 legs green. Windows-only file, so the Linux legs do not compile it.

Streaming a KDE desktop showed two cursors: the one the user was moving, and a
second one sitting underneath it that never moved. It was not KDE's — KWin 6.7.3
in cursor-as-metadata mode calls `setRenderCursor(false)` on every recorded buffer
and hands the cursor item to an exclusive `ItemTreeView`, so `shouldRenderItem()`
skips it and no pointer is ever painted into that stream. It was ours.

Both clients declared the render model as `captured && desktop`, so ANY released
pointer handed compositing back to the host. But releasing does not remove the
local cursor — it restores the ordinary window arrow over the video. The host then
blends its own pointer in underneath, and since a released client forwards no
motion, nothing drives it: it stays frozen wherever the host pointer was last left.
Caught live on the host with the render-model diag:

    cursor diag: client_draws=false blended=true live=Some((-1, 622, true))

x = -1 — parked on the streamed output's left edge, unchanged sample after sample,
while the user moved their own cursor around freely. Engaging capture flipped it to
`client_draws=true blended=false` and the duplicate vanished, which is why it only
looked "stuck when not dragging": dragging means engaged, and engaged was the one
state that behaved.

The host may composite ONLY while the client holds a grabbed, hidden pointer — the
capture model, engaged — which is the single state with no local cursor on screen.
Released now counts as "the client draws it": the host stops compositing and keeps
forwarding shape/state over the channel (the forwarder ticks on this side of the
flip), so re-engaging is seamless and the client's cached shape stays warm.

enricobuehler dd20a17edb test(host/library): the art tests build a file:// URL Windows can read
`local_art_bytes_is_confined_and_image_only` and `posix_local_art_is_classified_and_proxied`
built their `file://` values as `format!("file://{path}")`. On Windows that yields
`file://C:\covers\cover.png`, whose authority is `C:` — a UNC reference, not a local
file — so the read half failed on the box and the host suite was red there.

The parser is right and the tests were wrong: `@punktfunk/plugin-kit/library`'s `fileUrl`
emits `file:///C:/covers/cover.png` (three slashes, forward separators) and
`file_url_to_path` documents exactly that. A shared `file_url` helper now builds the value
the way the kit does, so both tests exercise the real plugin contract on both platforms
rather than a shape no plugin ever sends.

Found while gating the Playnite launch kinds on .173 — Linux CI never compiles these arms,
so the failure had gone unnoticed. Test-only: no product code changes.

enricobuehler 8ff2c2e1c6 feat(host/library): Playnite can publish again, and gets a fullscreen tile
The Playnite plugin emits `kind: "command"` for every game (a `start "" "playnite://…"`
shell line). The 2026-08-05 review made `command` operator-only, and `privileged_field`
refuses a PROVIDER reconcile carrying one — so on this branch the published
`@punktfunk/plugin-playnite@0.3.0` cannot publish anything at all. Not a launcher tile:
not one game. That is a regression against a shipped plugin, and it is the same hole
`launcher_ui` was created to close, one kind further along.

Two kinds, both host-owned so D1 holds — the plugin supplies a validated VALUE and
never a command line:

  playnite     valued by the game's GUID; resolves to
               explorer.exe "playnite://playnite/start/<guid>", the same
               protocol-via-a-concrete-EXE shape the `epic` kind uses. GUID-validated
               on the way in (so a bad value is a 400 the plugin author can act on)
               and again at launch.

  launcher_ui  now accepts "playnite" on Windows, resolving to
               Playnite.FullscreenApp.exe with Playnite's own install dir as the
               working directory.

Fullscreen, not Desktop, is the whole point of a couch tile — and it is also why this
one cannot ride the URI the games use: probed on .173, Playnite's registered
`playnite://` handler is bound to Playnite.DesktopApp.exe, so no URI opens fullscreen
mode. The exe is spawned directly, with the install dir read from Playnite's own
uninstall entry (HKCU, then HKLM for a machine-wide install), falling back to
%LOCALAPPDATA%\Playnite.

`valid_launcher_ui("playnite")` is answered by RESOLUTION rather than by a static list:
a host without Playnite installed refuses the entry instead of publishing a tile that
does nothing when a user clicks it. That is the same instinct that left Epic, GOG
Galaxy and the Xbox app off the list — each still needs its own verified activation,
and a guess would ship exactly that dead tile.

Gates: punktfunk-host 436 passed / 0 failed on .21 (the Linux arms), and the Windows
arms compiled and their library tests run on .173.

enricobuehler 883c317872 feat(clients/library): a launcher tile looks like one, on every client
The host has been able to describe a launcher entry since M2 — `role: "launcher"`,
the `steam_ui` and `launcher_ui` kinds — and the web console has grouped them into
their own rail since M4. No other client ever looked. `pf-client-core` decoded
`role` into an `is_launcher()` helper with zero call sites, and the shared console
model dropped the field entirely on its way to the renderer.

So a launcher tile arrived everywhere else as an ordinary game with no cover art:
indistinguishable from a title whose poster failed to load, sorted into the middle
of the alphabet, and captioned "Play".

One contract, implemented in each client's own idiom:

  * launchers never interleave with titles — they lead, and each group keeps the
    host's title order
  * grid surfaces get a labelled section; a coverflow keeps its single carousel and
    names the group the cursor is in, changing as it crosses the boundary. A second
    focus rail would mean a new up/down nav model in three renderers for two or
    three tiles
  * an art-less launcher gets an accent face naming its launcher, not a title
    monogram on the neutral one — "opens Steam", not "a cover that didn't load"
  * anything that is not `"launcher"` is a game, and a host that omits the field
    renders exactly as before (design D4's intended degradation)
  * launching is unchanged: the client sends an id, the host resolves the recipe

The grouping is enforced once per client stack rather than per screen. In the
console UI it is an invariant of `LibraryShared::set_games`, so the cursor
arithmetic, the art pump and every future consumer inherit it; on Apple and Android
it is applied where the library is fetched/parsed.

Fixed in passing: the Apple and Android store badges were hard-coded
`isCustom ? "Custom" : "Steam"`, so every Lutris, GOG, Heroic, Epic and Xbox title
was labelled "Steam". Both now carry the same store table the Rust clients use.

The CLI's `--library` gains a fourth column (`game`/`launcher`), appended rather
than folded into an existing one so anything reading the first three is untouched.

Gates: punktfunk-host 436 passed / 0 failed and pf-console-ui 49 passed / 0 failed
on .21 (three new tests), workspace clippy -D warnings and cargo fmt --check clean
there; `swift build` of the full PunktfunkClient and `:app:compileDebugKotlin` clean
on macOS; `cargo check` + `clippy -D warnings` for the Windows client on .173.

Still unproven on hardware: no launcher tile has been clicked on a real host — that
needs the plugins published, which needs this branch's base merged first.

enricobuehler 81b4f76c4d fix(client): a session ending on purpose stops reading as a failure
The desktop clients turned every host-side close into "Host ended the
session", and a reason string means "abnormal" to everything downstream:
the GTK and Windows shells raised a banner, the console overlay drew a
status strip. Quitting a game you launched yourself produced all of
that. Now only a host error or a lost connection carries a message; the
deliberate endings return the silence those shells already give a clean
exit, which is also what puts the console back in its library with
nothing in the way.

The Apple client gains the same distinction. It had one line for every
ending — "Session ended by <host>." — which is fine for an operator
stopping the session and wrong for a link that died, so each now says
what happened. A game exiting stays silent and returns to the library it
was launched from.

Both read the reason while the connection is still up, because tearing
it down is what makes it unreadable, and both fall back to their previous
wording when there is no verdict — an older core, or a close that raced
the read — rather than inventing a new one for a case they cannot see.
2026-08-06 14:30:46 +02:00
enricobuehler ec44496285 feat(client): tell clients WHY a session ended, not just that it did
A session ending was a single bit. A player quitting their game, an
operator ending the session from the console, a stop the client itself
asked for, a host crashing and a Wi-Fi drop all arrived as the same
"closed" — so every client had to write one message covering all of
them, and every client picked an error. That is how quitting your own
game came to be reported as trouble on all three.

The information was already there and thrown away: the host closes with
APP_EXITED when a launched game exits, with 0 when it ends the session
cleanly and 1 when it fails, and a link that simply dies never closes at
all. The connection watcher now classifies that into a
PunktfunkEndReason — local, game exited, host ended, host error, lost —
and latches it before the shutdown flag, since the two are read by
different threads and the reason must never arrive second.

Exposed as punktfunk_connection_end_reason. This replaces the
game-exited flag added a moment ago rather than joining it: that
question is one row of this table, and it was never released. Still
additive to any embedder that ignores it, and the host sends the same
bytes either way, so the wire is untouched.

`is_normal()` is the question nearly every caller actually has, so both
the Rust and C surfaces answer it directly rather than making each
client re-derive which of five values are worth alarming a user about.
2026-08-06 14:30:33 +02:00
enricobuehler d4dd5f7a3d feat(client): a game exiting takes you back to its library
Quit a game you launched from a host's library and the stream ended with
"Session ended by <host>." on the host-selection screen — an error
report for something you had just done on purpose, and several taps away
from starting the next title.

The host has always said what happened: it closes the connection with
APP_EXITED when the game it launched for a session exits, and that
code's own documentation describes this feature. Nothing ever read it —
a search across every client found zero consumers. (It also could not
reach anyone until the previous commit, since the close only happens
once the lease declares the game gone.)

The core now records the reason as it observes the close, latched before
the shutdown flag because different threads watch the two, and exposes
it as punktfunk_connection_game_exited. Purely additive: a client that
never asks behaves exactly as before, the host sends identical bytes,
and the wire version is untouched — ABI 17.

The Apple client asks while the connection is still up, then treats a
game exit as the normal finish it is: no error banner, and if the
session began as a library launch it reopens that library so the next
title is one tap away. Any other ending — a stop, the host going away,
network loss — is unchanged. The other clients keep their existing
end-of-session behaviour; the call is there when they want it.
2026-08-06 13:58:57 +02:00
enricobuehler 76e8bd1b98 fix(host/gamelease): a game that exited stops counting as running
When a launched game's processes are all gone, the watcher asks one last
out-of-band question before ending the session: does the launcher still
think the game is up? On Windows that reads Steam's per-app `Running`
registry flag. It was only ever meant to be a tie-breaker for a scan that
momentarily can't see the game — a launcher re-execing, an engine
relaunching itself into a new pid.

It had no bound. Honouring the flag reset the confirm window every pass,
so a flag Steam left set — it does that whenever it doesn't cleanly
observe the exit: it crashed, it was closed first, the game re-parented —
pinned the lease in `running` for the life of the host. The console kept
showing the game, `session_on_game_exit` never fired, and the only way to
get the stream back was a manual "End". Reported from the field on
Windows 0.24.0. `steam_running_hint` also believes the FIRST hive that
says so, so a stale flag in any loaded profile was enough.

The absence timer now keeps running instead of being reset, and that is
what bounds it: past `VETO_LIMIT` (30 s) with nothing of the game on the
box, the launcher's opinion is stale rather than early and the session
ends anyway, logged at WARN so it is visible. Ending a moment early is
the cheaper failure — the stream drops while the game lives, the user
reconnects, and nothing is ever killed. Ending never was the bug.

The rule is now a pure `exit_confirmed(gone_for, hint_running)` with a
test. The watch loop polls a live process table and can't be unit-tested,
which is exactly how an unbounded veto shipped unnoticed.

A field report from an iPad: the host is not found on first run, and
restarting the client finds it. Pull-to-refresh appeared to do nothing.

Both were real. The Apple client's discovery had three ways to go
permanently deaf, each needing an app relaunch to clear:

- A failed resolve was never retried. `browseResultsChangedHandler`
  only fires when the result SET changes, and a host whose resolve
  failed is still in the set — so nothing ever re-offered it.
- A stuck resolve never ended. `NWConnection` has no timeout, so the
  throwaway UDP flow used to resolve an address could sit in
  `.preparing`/`.waiting` forever, and a service with a connection in
  flight was skipped.
- `NWBrowser` parking in `.waiting` was ignored (only `.failed`
  re-armed). On iOS that is where the local-network privacy prompt
  lands on first launch after install: the browse starts, the system
  asks, and the browser waits. Granting does not revive that browser —
  only a new one sees the grant. That is the reported first-run bug.

HostDiscovery now runs a 1 Hz sweep that times out stuck resolves,
retries failed ones on a 1→30 s backoff, and re-arms a browser that
stopped working; the advert's TXT is re-read on every browse report, so
a host that re-keys or flips its pairing policy is followed. Returning
to the foreground re-arms the browse (iOS/tvOS: `onAppear` does not
fire across background/foreground, and a suspended browse stays dead).

Pull-to-refresh did nothing because there was no `.refreshable` in the
client at all. Added, plus the explicit control the report asked for:
a toolbar Refresh on iOS/macOS, an action-row button on tvOS, a Rescan
tile in the gamepad launcher, Scan Again on the empty state, a
header-bar button in the GTK client, a hosts-page button on Windows,
and Scan again on Android. Decky already had one.

The desktop/Android browses needed a rescan trigger to make those
buttons mean anything: mdns-sd re-queries on a doubling backoff capped
at ONE HOUR, so a long-lived browse is effectively passive and a host
that appears later can stay invisible. `discovery::Rescan` forces a
fresh query; the wake-and-wait loops use it too, so a host that just
booted is noticed in seconds rather than at the next backoff tick.

Also fixed, found on the way: clients/windows/src/discovery.rs is a
second copy of the browse that d0fa8bd3 ("pin mDNS discovery to IPv4 on
every client") missed. It took an arbitrary first address, so when a
host's OS responder answered AAAA the Windows GUI rendered a card that
failed on every click. It also never noticed a dropped receiver, leaking
a thread and a :5353 socket per wake-and-wait.

Gates: Apple macOS + iOS (arm64-apple-ios17.0, proven non-vacuous) build
clean, 195 tests pass incl. a new one asserting a rescan re-finds a
still-advertising host. On .21: fmt, clippy --all-targets -D warnings
and build clean for pf-client-core + client-linux + client-session,
117 tests pass. Android :kit: and :app: compileDebugKotlin clean.
The Windows client is UNGATED — its CI runner was unreachable.

The console settings were one 30-row scroll, which on a Deck meant thumbing past
Video and Audio to reach the pad settings. They are now split across sections —
Stream · Video · Audio · Controller · Interface · Profiles, plus Input on the
desktop console, which alone carries the touch/mouse rows. L1/R1 walks them,
each section remembers where its cursor was, and the names are the same word on
every client so a setting is where you looked for it last.

Shoulders are not the only route, because a D-pad remote hasn't got any: on
Android, Up from the first row moves onto the strip (left/right walks sections
there, A drops back in), and on tvOS the pills are focusable, so the focus
engine handles it — a Siri Remote has no extended gamepad profile and never
reaches the input poll at all. The desktop console needs neither; PageUp and
PageDown already map to the same events.

New "Background" row, six palettes: Violet (the brand default), Tide, Forest,
Ember, Rose, Graphite. A palette is a hue rotation plus a saturation scale over
the ONE colour field each client already draws, so every palette inherits its
structure and Violet is the identity transform — existing installs see exactly
what they see today. The maths is ported three times (Rust/Swift/Kotlin) under
one shared `ui_palette` key, with the same assertions pinned in each language.
It is presentation only, so it is a device preference and never part of a
profile.

The form screens no longer have a backdrop of their own. Settings, add-host and
pair used to sit on a still gradient; they now wear the same living field at a
calm mix — pools dimmed onto the palette's own corner colour, vignette halved so
rows that run to the edges don't get crushed. On the desktop console that
collapsed the old aurora-over-static crossfade into one shader pass with a
chased uniform. Motion speed is identical in both modes on purpose: changing it
would make the field jump mid-transition. Nothing in the gamepad UI is backed by
a static image now, and Reduce Motion (Apple) / "remove animations" (Android)
still freeze it.

Also: the settings screen had no raster coverage at all — the eyeball dump is
`#[ignore]`d — so a new test draws every tab, and the Android screenshot set
gains a console-settings scene. Both earned their keep immediately: the renders
showed the extra hint pushing "Done" off a 360 dp phone (the legend scrolls now,
and the Section cell only appears where shoulders exist) and the form backdrop
crushing its own edges.

Reported from the field (2026-08-05): a fresh Windows 11 box with a data
partition, "New apps will save to: D:", and the client installed there. It
launches, finds hosts and streams — but no setting and no profile survives a
restart. Reinstalling to C: fixes it completely. The reporter's read was "it's
in read-only mode", and that is almost exactly right.

The one clue that localises it: the client creates its mTLS identity with a
plain `fs::write` on first run and hard-exits if that fails. Their app started,
so ordinary file creation in the config directory works. Only the config stores
were being lost — and those are the three files that go through `write_atomic`,
which writes a sibling temp and renames it over the target.

The rename is what breaks. The client ships as a full-trust MSIX package, so
its `%APPDATA%` writes are redirected into the package container. When the
package lives on a secondary drive, Windows keeps that redirected state on the
package's own volume: `C:\Users\<u>\AppData\Local\Packages\<pfn>\` stays a real
directory on C:, but its children (LocalCache, RoamingState, …) are junctions to
`D:\WpSystem\<SID>\…`. Both sides of our rename still spell `C:\Users\…`, so
nothing looks unusual, but they can resolve across that junction boundary — and
`std::fs::rename` is `MoveFileExW` with `MOVEFILE_REPLACE_EXISTING` and *not*
`MOVEFILE_COPY_ALLOWED`, so a cross-volume move fails outright rather than
degrading to a copy. Creating files still works, which is why everything else
about the install looks healthy.

So the fix is not to make the rename work — it is to stop treating it as the
only way to persist. `write_atomic` now falls back to writing the target in
place when the atomic route fails. That is the same operation the identity files
already use, and those demonstrably round-trip on the affected installs, so the
fallback lands on a path we know resolves. It trades crash-atomicity for exactly
the writes that would otherwise be lost, and nowhere else: temp+rename stays the
normal route everywhere it works.

Writing into a redirected location cannot desync from reading it — Microsoft
documents one private-location-first resolution order for both, so whichever
layer a write lands in is the layer the next read finds. The fallback verifies
anyway, by reading the bytes straight back: a write that reports success and
disappears is precisely the bug being fixed, so this path does not get to claim
success on an `Ok(())` alone. It costs nothing normally — it only runs on an
install that has already shown it does something unusual.

Two things this uncovered on the way:

The temp file was a single shared `<name>.json.tmp`, but these stores have five
whole-file writers (WinUI shell, session, console UI, CLI, Decky). Two saving at
once collide on it — on Windows the second write hits a sharing violation, and
worse, one process can rename the other's half-written bytes over the target.
The scratch path now carries the pid.

And none of this was visible to anyone. Every save on this page is
fire-and-forget by design (a failed settings write must never take a stream
down), so ~15 call sites discard the error and the UI cheerfully shows the
toggle you just moved. The reporter had no log file to send either, because
"Open log folder" was handing out a phantom path — a separate bug, already fixed
in f3c0ee47 but not in the 0.24.0 they were running. `store_health` records the
last persistence failure centrally, and Settings shows an error bar naming the
path when the store is refusing writes, so a client that cannot save says so
instead of pretending.

`update.rs` had hand-rolled the same temp+rename inline, so it neither cleaned
up its temp on a failed rename nor picks up the fallback; it now goes through
the one writer. The update floor silently never rising is how a declined update
comes back forever.

Deliberately NOT done: disabling MSIX AppData virtualization in the manifest
(`desktop6:FileSystemWriteVirtualization`). It would stop the redirection at the
source, but every existing packaged install's settings, profiles and pairings
live inside the container today — turning it off points the client at an empty
real `%APPDATA%` and silently resets all of them. That needs a migration, not a
manifest flag.

Also considered and not taken: resolving the destination directory with
`GetFinalPathNameByHandleW` and creating the temp inside the resolved path, to
keep atomicity. It does not reliably close this hole — when the target file
exists only in the unvirtualized layer while its directory resolves to the
private one, the rename still straddles the boundary — and it would rest on
canonicalisation behaving through the redirection, which we have never verified
on a packaged run.

Verified on the RTX box (.173, Windows 11 26200), which is the platform that
actually has these rename semantics: `cargo fmt --all --check`, the full
`pf-client-core` lib suite (109 passed), and clippy `-D warnings --all-targets`
on both `pf-client-core` and `punktfunk-client-windows` — all clean. Also green
under linux/amd64 (116 passed). Three new tests: the pid-scoped scratch path,
the fallback actually persisting and reading back when the atomic route is
blocked, and a genuinely unwritable store surfacing its error instead of
swallowing it.

The mechanism above is established from documentation and third-party reports,
not from a reproduction on a second-drive install — that box does not exist
here. The fix does not depend on the diagnosis being exactly right: it repairs
any install where the rename fails but a direct write succeeds.

Design D4 promised entries that open the LAUNCHER — Steam Big Picture, Heroic,
Lutris — and the plumbing for it landed in M2/M4: the `role` field, the
`steam_ui` kind, the console's Launchers rail. But nothing could flow through it
for anything except Steam.

D4 said the other launchers would ride the `command` kind. The 2026-08-05 review
then made `launch.kind = "command"` operator-only (it is handed to a shell), so a
plugin publishing one is refused with a 403. The two changes are individually
right and jointly leave a hole: `steam_ui` was the only launcher kind a plugin
could publish, so a Heroic or Lutris tile was unreachable.

New `launcher_ui` kind, valued by store id. One kind rather than one per store
because every launcher except Steam has exactly a single UI to open; Steam keeps
its own kind because it genuinely has two. D1 is preserved — the plugin names a
launcher, the host builds the command, and no shell string crosses the wire:

  heroic -> the same native-or-Flatpak resolution the `heroic` game kind uses,
            minus --no-gui and minus the URI, so the window itself opens
  lutris -> bare `lutris`, which opens the window (the URI form is `lutris_id`)

Platform-gated to what this host can actually resolve, and validated INBOUND: a
value naming a launcher this OS cannot open is a 400 the plugin author can act
on, not a tile that silently does nothing when a user clicks it. Windows
launchers (Epic, GOG Galaxy, Xbox app) are deliberately absent — each needs its
own verified activation and a guess would ship exactly that dead tile.

Also closes a WP4.3 item I under-delivered and did not flag: the console's
add/edit form had no way to mark an entry as a launcher, so even hand-adding one
was impossible. It now has the checkbox — and `formFrom` round-trips it, without
which editing a launcher entry would silently demote it to a game, which is the
precise bug that file's own comment warns about.

Still unproven on hardware: no launcher tile has been clicked on a real host.

PR #58 hardened the art proxy in the same three files this branch rewrote, and
the two changes pull in opposite directions: #58 narrowed what the host will read
from disk, while WP1.2 widened what counts as a local art path so an extracted
scanner's covers can be served at all. Resolved so the widening goes through the
gate rather than beside it.

Kept from #58, unchanged: art_path_is_confined (UNC refusal, canonicalize-or-
refuse, config-dir exclusion, roots check), the image-extension whitelist,
sniff_image_type, validate_art_paths as write-time validation, the AuthLane
privileged-field check on every entry in a reconcile payload, and the launch
redaction in GET /library.

Three reconciliations:

  * `local_art_bytes` converts a `file://` value to a path BEFORE calling
    art_path_is_servable, so the confinement check and the read see the same
    path. Ordering is the point: percent-decoding happens before
    canonicalization, so a `%2e%2e` escape cannot hide from the traversal check.
    Pinned by a test.

  * `art_roots()` gains $HOME on POSIX. This is the one that would have bitten
    silently: the list was empty on non-Windows, which was correct while
    is_local_art_path was Windows-shaped (Playnite is Windows-only, so nothing on
    a POSIX host was ever classified as local art and the confinement had nothing
    to confine). Once WP1.2 classifies POSIX paths as local, an empty root list
    is not "secure by default" — it serves NO plugin art on Linux, which is every
    cover the lutris and steam plugins emit. $HOME is the exact analogue of the
    Windows users base #58 already ships, and covers Steam's librarycache and
    grid overrides, Lutris's coverart/banners (both copies), Heroic's caches and
    all the Flatpak variants. It is not the load-bearing control: a value still
    needs an image extension, must canonicalize to a real regular file inside a
    root and outside the config dir, and must CONTAIN image bytes.

  * The two tests that both wanted to mutate PUNKTFUNK_LIBRARY_ART_ROOTS became
    one. Cargo runs tests as parallel threads of a single process, so two tests
    setting the same env var race. The `file://` and confinement assertions moved
    into #58's existing confined test; what remains of the WP1.2 test is the
    pure classification/rewrite half, which touches neither env nor filesystem.

Also: `steam_ui` was missing from the list of host-resolved launch kinds in
privileged_field's doc comment and in the 403 a plugin sees. Prose only — the
check is a denylist (prep, launch.kind = "command"), so steam_ui was never
actually refused — but a plugin author reading that error would have concluded
otherwise.

Gates on .21: punktfunk-host 433 passed / 0 failed (including #58's H-2 tests and
the new file:// ones), full workspace tests clean, workspace clippy -D warnings

Closes H-3 of the 2026-08-05 review, the last of its six highs. A plugin's
interface was reverse-proxied onto the console's own origin and framed with
`allow-same-origin`, so plugin JS ran as first-party code on that origin: one
`fetch('/api/**', {credentials:'same-origin'})` and the BFF attached the
operator's ADMIN bearer. That reached everything `plugin_may_access` withholds
— arm pairing, read the host PIN, approve a device, read `/hooks`. The "open
in new tab" link was the same escalation with no iframe involved at all.

The fix is not a sandbox attribute, and it is worth writing down why, because
the obvious change is the one that does not work. Dropping `allow-same-origin`
gives the frame an OPAQUE origin; its subresource requests are then cross-site;
the `SameSite=Lax` session cookie stops being sent; every plugin asset 302s to
/login and the frame is blank. Nothing about the new-tab link is helped either.

So the origin moves instead. A second listener on its own port (default
PORT + 1) serves plugin UIs and nothing else:

  different ORIGIN — scheme+host+PORT — so the same-origin policy separates the
                     plugin from the console: it cannot read the console's DOM,
                     its cross-origin fetch of /api/** is unreadable (no CORS)
                     and cannot mutate (Sec-Fetch-Site sees same-site).
  same SITE        — cookie scope ignores the port and SameSite is computed on
                     the site, so the session cookie still reaches the plugin
                     listener and plugin pages keep working.

Enforcement is two refusals and both are load-bearing: the console origin
refuses /plugin-ui/**, and the plugin origin refuses everything ELSE — above
all /api/**, which would otherwise hand the admin bearer right back to plugin
JS that is now same-origin with that listener. Both are unconditional: if the
plugin port cannot be bound, plugin UIs are DISABLED and the console says so,
rather than falling back to the arrangement this exists to remove.

Two consequences that would otherwise bite in the field:

  The port has to be open. Done for the Windows netsh rule, the firewalld
  service and the ufw profile.

  A browser stores a self-signed-certificate exception per ORIGIN, including
  the port — and a certificate interstitial can never be shown inside an
  iframe, so the frame would just sit blank with nothing on screen explaining
  why. A `no-cors` probe distinguishes it (a TLS failure rejects; any HTTP
  answer, even 401, resolves) and the console renders a card linking the
  operator to open the port once in a real tab.

Also here: the health probe moved server-side to the console origin (it used
to rely on being same-origin with the plugin), the postMessage listener now
verifies `event.origin` — a real check rather than a tautology — and
plugin-kit's `postMessage(..., "*")` is documented as load-bearing, since
narrowing it to `location.origin` would now target the plugin's own origin and
silently drop every message.

Verified against a running console with a fake mgmt API and a fake plugin:
console /plugin-ui/** → 404; plugin-origin /api/v1/hooks, /, /login,
/_auth/logout → 404; plugin page loads 200 through its own origin;
unauthenticated plugin origin → 401 (not a redirect to a /login it does not
serve); a forged x-pf-listener header changes nothing on either listener; the
plugin's own Clear-Site-Data / Access-Control-Allow-Origin / Set-Cookie are
dropped by the proxy allowlist; the plugin origin's CSP names the console as
its only frame-ancestors source; and with the port squatted, ui-config reports
`unavailable`, the console still refuses /plugin-ui/**, and the console itself
keeps working.

Still wants on-glass confirmation in a real browser — the cookie and framing
behaviour is reasoned from spec, not observed.

enricobuehler 8103958169 fix(security): the plugin lane stops being a way in
Acts on the 2026-08-05 host security review. 36 of its 38 findings; the two
exceptions are recorded below and in the review doc.

The review's headline is that `plugin_may_access` was the one authorization
gate in the system that was allow-by-default — a hand-maintained denylist of
route prefixes, where every sibling gate is deny-by-default. Its own doc
comment names the two capabilities it exists to withhold, and both were
reachable one route over, because ~1450 commits of new routes were added and
the list was never one of the things anyone remembered to update.

So the gate is now an allowlist, and a test walks the live route table and
fails the build for any route that has not been deliberately classified for
both non-admin lanes. That test is the actual fix: it is what stops the next
route from arriving pre-authorized.

Route reachability and field authority turned out to be different questions.
A provider plugin has to be able to reconcile its own library entries — that
is what a scanner plugin IS — but `prep` and a `command` launch inside that
payload are handed to `/bin/sh -c` as the host user, and every execution site
documents them as operator-typed. Requests now carry the lane that authorized
them, and those two fields are refused to everyone but the operator's own
token.

The art proxy read any absolute path off disk in the host process, which on
Windows is LocalSystem, from a path the plugin lane could write and then read
back — so it yielded `mgmt-token`, which is full admin. It now serves only
real images (extension AND magic bytes, so a renamed secret fails), only from
inside an allowed root, only after canonicalization, and never over UNC; and
a path it would refuse to serve can no longer be persisted in the first place.

On Windows, the config-dir hardening was skipped exactly when it was needed —
it ran only in the branch that CREATES host.env, so the case it was written
for (a local user pre-created the directory and planted one) was the one case
it never ran in. It is now unconditional and first, an existing host.env is
re-owned, and the inheritable OWNER RIGHTS ACE that kept an attacker's files
theirs after the directory was re-owned is gone. The identity and token
readers were hardening the directory only on the path that GENERATED a new
secret, so a planted cert/key or token was adopted verbatim and permanently;
they harden before the first read now.

`ensure_admin_only_source` is implemented. The 2026-07-05 audit recorded it as
FIXED and it was in no commit in this repository's history — the local EoP it
described was live, and it is the payload half of the config-dir chain above.

Also: the three input planes are bounded and lossy like the mic plane on the
same loop already was; Android's library client no longer accepts any
publicly-trusted certificate for the pinned host; the usbip vhci nodes get
their own group instead of riding on `input`, which every packaging scriptlet
tells users to join; a registry URL can no longer inject a TOML table into
bunfig.toml; the pairing cooldown is charged before the arming state is read,
so armed/disarmed is no longer a free oracle; and the whole Low tier, of which
the two worth naming are a clipboard MIME NUL that panicked the host on one
control message, and an unauthenticated global logout that let any LAN peer
sign the operator out on a loop.

NOT fixed, deliberately:

  H-3 (plugin UIs framed allow-same-origin). Dropping allow-same-origin does
  not work: the document's origin goes opaque, its subresource requests are
  then cross-site, the SameSite=Lax session cookie is not sent, and every
  plugin asset 302s to /login. The "open in new tab" link is the same
  escalation with no iframe at all, so the sandbox attribute is not where this
  gets fixed either. It needs a second listener — a distinct origin that is
  still the same site — which changes the console's deploy model and wants
  on-glass validation. The mechanism and the dead end are written down at the
  iframe.

  H-6 registry authentication, whose other half lives in unom/infra. The
  in-repo halves are done: workflow_dispatch inputs no longer interpolate into
  run: blocks (one of them in the step holding UPDATE_MANIFEST_KEY), and the
  syft installer is pinned to its tag instead of main. Digest pinning is left
  until the registry is authenticated, because a tag — content-keyed or not —
  can simply be overwritten while anonymous pushes are accepted.

M-5 is half done: the oracle is closed, but binding the arming window needs
the console to learn the fingerprint first, which is a knock-then-bind flow
rather than an edit.

Verified: cargo fmt --all --check clean; cargo check --all-targets green on
Linux and on Windows (confirmed non-vacuous — a planted type error in
windows/install.rs fails the build); scripts/xcheck.sh windows check green;
cargo test -p punktfunk-host --bins 416 passed, the single failure being
gamestream::stream::tests::sender_delivers_batches, the known qemu-environmental
UDP-loopback flake that fails identically on clean main in the same container;
cargo test -p pf-clipboard 13 passed; web console typechecks.

enricobuehler 3d4a659959 feat(host,sdk,kit): store claims, launcher entries, and plugin sources on the wire
M2 of design/library-scanner-plugins-implementation-plan.md. Everything a
library scanner plugin needs is now expressible over the API; all additive.

WP2.1/2.2 — store claims (D2). library.json gains a v2 shape ({entries, claims})
that loads the v1 bare array unchanged and is written on the first mutation.
PUT /library/provider/{p}?store=<s> claims a store for a provider: its entries
then surface with deterministic <store>:<external_id> ids and the store's own
badge instead of opaque custom:<id> ones. That identity is the whole point —
entry ids, GameStream FNV app ids, client art caches and Moonlight pins all
survive a title moving from an in-host scanner to a plugin. One provider per
store (409 otherwise); DELETE releases; an empty reconcile does NOT (a store can
legitimately have zero titles). While a claim is held, all_games() skips the
matching built-in scanner, so the two never double-list during the bridge.

WP2.3 — DetectHint gains steam_appid and env_marker, the two store-derived
signals the host used to read for itself. Without them a steam plugin's lease
tracking would drop from reaper-exact to dir-prefix, and Heroic-under-Proton
would lose the only signal that works. Malformed markers are dropped, not
honoured — this feeds a path that can end processes.

WP2.4/2.5 — role: game|launcher on the entry shapes (serde-default, skipped when
default), and a steam_ui launch kind valued bigpicture|desktop that opens the
Steam client itself. Validated inbound as well as at launch.

WP2.6 — GET/PUT /library/scanners generalizes to SOURCES: built-in scanners
minus claimed ones, plus claimed stores, plus any provider with entries. The
same library-scanners.json disabled-set backs all of them and the ids match by
construction, so a user's disabled state carries over verbatim through the whole
migration. A disabled plugin source has its entries filtered at read time,
exactly like a disabled scanner.

WP2.7/2.8 — plugin registration gains a category field (the console keeps
library plugins out of the nav); index entries gain categories and per-platform
detect probes, evaluated existence-only into CatalogEntry.detected so the host
never re-grows per-store knowledge. Index SCHEMA stays 1 — additive.

WP2.9 — OpenAPI + SDK regenerated on Linux; kit wire widened (LaunchSpec.kind is
now a plain string documented against the host's vocabulary — closes G3), and
ProviderClient.reconcile takes an optional store and returns the host's echoed
entries so a caller can detect a pre-M2 host silently ignoring the claim.

Also fixes a bug the S3 spike turned up: is_steam_launch gated on a steam:// URI,
so a steam_ui launcher entry would have skipped BOTH gamescope's --steam mode and
the B1 single-instance free — on a box autologged into game mode, the nested
second Steam would see the first and exit, crashing the spawn. It now tests the
first token.

Gates on .21: workspace tests green (punktfunk-host 425 passed), workspace
clippy -D warnings clean, cargo fmt --all --check clean, OpenAPI drift test
green. plugin-kit: tsc clean, 20 tests pass.

enricobuehler a418d2852a refactor(host/library): launch helpers into launch.rs, art proxy resolves any id
M1 of design/library-scanner-plugins-implementation-plan.md — behavior-frozen
groundwork for lifting the six scanners out into plugins.

WP1.1: heroic_command/heroic_launch_prefix, epic_launch_uri, gog_spawn,
valid_steam_appid and shortcut_gameid move into library/launch.rs with their
unit tests. The scanner modules beside it now do enumeration only, so they can
be deleted wholesale later without taking launch logic with them (D1).

WP1.2: is_local_art_path accepts file:// (the plugin contract) and POSIX
absolute paths, excluding the two /-leading shapes the host itself emits (its
own /api/ proxy path and protocol-relative CDN URLs). local_art_bytes
percent-decodes and converts a file:// value first. The art proxy and
fetch_box_art resolve ANY id against library.json before the legacy steam:
branch, so a plugin's entries serve art without the host knowing its store.

No API change; no user-visible change.

Stall program T2 (amplification kill), the phantom-latch half. A deciding
window that delivered under a quarter of the target rate (a host-side
capture stall, an outage, a mid-window pause) carries starvation-shaped
distress — a jump-to-live flush, a keyframe-ask burst — that the decode-cap
latch read as decoder evidence: under a periodic capture stall (the RDNA4
standby-sink field cases, one stall every ~5 s) every edge offers another
'backoff' at the SAME rate, and one pair latches a phantom decoder knee at
whatever rate the display driver happened to interrupt. The session then
fights the cap's re-probe ladder (+12.5% per 16-128 clean windows) for
minutes on a decoder that was never the problem.

Starved windows still back off (real damage deserves the safe response) but
take the same 'not a knee sample either way' arm as a draining backoff:
they neither latch a decode cap nor erase the reference a genuine choke
set, so a real knee's pair still finds itself around the interruption. The
¼ bar sits deliberately far under the ×¾ utilization bar climbs require.

Gates: 44 abr tests green (2 new: the stall-cycle no-latch scenario and the
reference-preservation scenario), full core lib suite 346 green
(--features quic), fmt + clippy clean.

enricobuehler e5416646f9 fix(host/send): a stall-resume frame paces at the proven rate instead of blasting
Stall program T2 (amplification kill), the resume-burst half. The native
pace budget was min(0.9 × time-to-deadline, overflow at ~3× stream rate) —
for steady-state frames the rate term is smaller and decides, but for an
OVERSIZED frame (a capture-stall resume carrying seconds of scene delta, a
cold IDR) the deadline term clamped a multi-interval overflow into the
remainder of ONE: an instantaneous many-×-stream-rate blast that overruns
the socket tx-buffer and loses the very frame that would have ended the
freeze. Field fingerprint across three RDNA4 standby-sink cases:
WSAENOBUFS(10055) + loss_ppm spikes at stall edges, then a recovery-IDR
round trip per retry while the client shows 'current bitrate 0.1'.

The budget is now the overflow's wire time at the pace rate itself
(send_pacing::native_budget, pure + unit-tested), bounded by an absolute
100 ms ceiling so a pathological frame can't park the send thread; the
deadline stays a target, never a license to blast. Steady-state frames
produce byte-identical schedules (the rate term already decided);
PUNKTFUNK_PACE_FACTOR=0 keeps the legacy deadline-only spread; the
GameStream plane's Moonlight-pinned schedule is untouched.

Gates: host clippy --all-targets -D warnings + 9 send_pacing tests green
(linux/amd64 container), fmt clean.

Everything the 2026-08-03 haptics sweep filed against the pad-audio branch (P2 + P3).
Four of them are the difference between a feature that works and one that fails silently.

**B6 — nothing ever un-muted the coils.** Every rumble report asserts `HAPTICS_SELECT`,
which is SDL's "disable audio haptics" bit: the firmware mutes the very voice coils the
0xD1 stream drives. No code anywhere cleared it again, so ONE rumble left tier-A haptics
silent for the rest of that pad's life — no error, nothing in a log, and the host happily
streaming into a muted actuator. `DsDevice.ds5AudioHapticsReport` is the documented undo
(flag0 with both bits clear); written EP0-direct when the stream starts and again after a
rumble stop while a stream is live, because the stop report re-mutes on its way past.

**B10 — the desktop mix could reach a controller's coils.** Pad endpoints were filtered out
inside `plan()` only. The watchdog, Follow mode and the parked default all go through
`judge_default`, which classifies by NAME — and a pad endpoint is deliberately stamped
"DualSense Wireless Controller" so games treat it as the pad's speaker. No name rule could
ever catch one. It now refuses them by identity.

**B27 — an out-of-range pad aliased onto a real slot.** The 0xCD plane's pad is the only u16
index and every consumer narrowed it with `as u8` on an assumption nothing enforced, so wire
pad 256 steered pad 0's speaker volumes. Rejected at the decoder, which makes the narrowings
lossless by construction. An existing test had pinned the bug in place, asserting that wire
pad 513 round-trips; corrected, plus a test for the 256→0 alias specifically.

**B7 — caps that arrived late were never announced.** The renderer commits the tier-A trade
only once its sink opens, which is well past the arrival burst's two 100 ms ticks, and
`set_pad_audio_caps` only stored an atomic. The client believed it had pad audio while the
host emitted nothing. The input task now compares the live registry against what the last
arrival actually carried and re-arms the burst itself — no new plumbing, and no extra traffic
when nothing changed.

The rest: `needs_aeb_kick` is finally ACTED on (R4) — a stored-but-not-served endpoint is
declined rather than opened, because `AUTOCONVERTPCM` makes it succeed and mis-route; a failed
provisioning no longer latches `PROVISIONED` for the process lifetime (R5), and `host_cap`
retries, so a host that started while the audio stack was busy recovers at the next connect
instead of the next reboot; the loopback init timeout reaps its thread instead of detaching one
per ~2 s reopen (R6); kind-change restarts are bounded (R3) since the trigger is a client-sent
arrival; the devtest uses the endpoint's real channel mask (B11) instead of letting wasapi
derive 0x0F against the endpoint's 0x33; the render loop asks `is_session_ended()` rather than
spinning at nice -16 (R12); short writes are counted and reported instead of dropping the tail
in silence (R13); and a frame addressed to another pad is dropped before it can seed the gap
tracker from a foreign sequence space (R14).

Verified: punktfunk-host clippy -D warnings **0 on a real Windows box**; Linux/amd64 clippy 0
with **589 tests** (pf-client-core 114, pf-inject 101, punktfunk-client-android 20,
punktfunk-core 345+1+8); Android :kit: tests + :app: compile green; fmt clean.

Six punktfunk-host tests fail on that Windows box. FIVE fail identically on a tree with no
pad-audio code at all (QUIC `Rejected(SetupFailed)` — the box's network environment); the
sixth passes 3/3 in isolation and only failed under the parallel run, on a locally-bound
ephemeral port. Neither is this change.

Still owed: on-glass. This is a hardware feature and none of it has been on a real DualSense
since the merge.

enricobuehler 0a72959ef7 Merge main into feat/android-pad-audio
86 commits of main, including the whole M1-M12 haptics sweep. Twelve conflicting files;
three of them were more than textual.

**The capability bits collided.** Both branches allocated the SAME wire bits for DIFFERENT
features: `client_caps 0x04` and `host_caps 0x20` are redundant desktop audio on main and
pad audio here. Merged naively, a peer would negotiate one and get the other. Pad audio
moves to the next free bits — `CLIENT_CAP_PAD_AUDIO = 0x08`, `HOST_CAP_PAD_AUDIO = 0x40` —
and the `abi.rs` mirrors move with them (their compile-time equality assertions caught the
mismatch, which is exactly what they are for).

**Both branches also claimed ABI v15.** Main's shipped (the rumble-policy floor), so the
pad-audio surface becomes **v16**.

**`native/input.rs` would have reintroduced a fixed bug.** This branch resets
`rumble_seq[idx]` on pad removal; M1 established that the client's reorder gate is
per-connection with no reset path, so restarting the host counter strands every later
envelope until it climbs back. Took main's seq-preserving `clear_pad_feedback` and kept only
the branch's `pad_streams.stop(idx)`.

The rest: `wiring_plan::plan` now delegates to main's `plan_with_formats`, so the pad-endpoint
filter moved into that body and the predicate behind it is factored out as `is_pad_render`
(also what B10 needs); `Ds5Feedback::AUDIO` derives from main's `REPORT_ID_LEN` like its
siblings; `AudioCtl` joins the explicitly-listed unhandled variants so the guard-false case is
covered rather than swept up by a `_`; `include/punktfunk_core.h` regenerated rather than
hand-merged.

Twelve findings from the sweep's DRY/docs/dead-code tail. Most are small; three found
real defects hiding behind the duplication.

**The UHID event ABI existed five times.** Every UHID gamepad backend — DualSense,
DualShock 4, Switch Pro, Steam Controller, Steam Controller 2 — carried its own verbatim
copy of the kernel's constants plus its own `put_cstr`, and they had already drifted:
`switch_pro` was missing the SET_REPORT pair entirely, and `steam_controller` read a
FIXED 16-byte SET_REPORT window instead of the event's own `size`. That last one is a
bug in both directions — a longer report was truncated, and a shorter one had the parser
reading whatever the reused event buffer still held past the payload, i.e. acting on
rumble values the game never wrote. Now one `uhid_abi` module owns the numbers plus the
two accessors that are easy to get subtly wrong, with tests on exactly that.

**A dead force-feedback id fallback.** ff-core's `input_ff_upload` picks a free effect
slot and writes it into the effect BEFORE uinput forwards the request, so the `id == -1`
branch could never run — and allocating from a local counter would have been the wrong
answer anyway, since the kernel owns that id space. Removed, with a `debug_assert` where
it stood.

**Apple's HID path silently dropped weak rumble.** `hidByte` took the top byte with no
non-zero floor, so every amplitude below 0x0100 rendered as exactly nothing. Android has
always floored it at 1; this was the odd one out. That converter also existed twice
byte-identically inside one Gradle module — now one `wireAmplitudeToByte`.

Also: the DS5 output-report layout gets named offsets (`dualsense_proto::out_report`)
documenting all three transport bases — USB 0, SDL payload −1, Bluetooth +2 — since the
differing bases are transport-forced, not drift. `pf-client-core` cannot import them (it
and `pf-inject` do not depend on each other, and a DualSense layout has no business in
`punktfunk-core`, their only shared crate), so its copy now DERIVES its offsets by
explicit subtraction and a test pins the relationship. `PUNKTFUNK_HID_EFFECT_MAX` sizes
the struct it describes instead of a second literal 11 — the header now emits
`uint8_t effect[PUNKTFUNK_HID_EFFECT_MAX]`. The rumble policy engine's `min_pulse_ms`
and `keepalive_ms` docs stop naming cases nothing implements: no in-tree caller sets
`min_pulse_ms`, and the macOS DualSense-over-BT keepalive the doc cited CANNOT be served
by the quirk, because that renderer skips writes whose levels are unchanged and would
swallow the engine's re-emit — it keeps its own keepalive instead. `TrackpadHaptic` is
marked as staged scaffolding (the tag is on a shipped wire; removing the variant would
not reclaim it). Three ×257-vs-`<<8` doc comments corrected — the scaling itself is fine,
both round-trip to 255. `backstop_ms.max(160)` deleted as unreachable (the engine floors
at 500). New tests for `Ds5Feedback` and for the Android rumble JNI packing on BOTH sides,
with `MAX_PADS <= 16` now a compile-time assertion rather than a comment.

Closes S1-S9, S11, T2, T3 (design/haptics-sweep-2026-08-03.md M12).

S11's second half is NOT a defect and was left alone: `clients/session/src/main.rs`
calls `set_forwarding` unconditionally on every params-build (its own comment explains
why — browse mode reuses one service across launches), so `Ctl::Forwarding` routinely
arrives unchanged and that early-out is what stops a redundant `sync_open` + Valve-HIDAPI
cycle each launch.

Three things a field report (Discord, upgrade from 0.1x) turned up, all on the
Windows host.

1. "It thinks I have Sunshine/Apollo running." It didn't — they were uninstalled.
   Both uninstallers leave their config/log directory in Program Files behind, and
   `detect.rs` counted a bare directory, or a service registered at ANY start type
   (including `disabled`), as a live conflict. The installer's own probe was
   narrowed to "service start type <= 2" after exactly this cried wolf on a
   `winget install`, and the tray dropped its always-on warning for the same reason
   in 3e782852 — the runtime probe never got the same treatment, so the one surface
   the user actually looks at kept shouting. `Evidence::is_active` now draws the
   line (running, or set to start on its own) and only active detections reach the
   startup warning, the `detect-conflicts` exit code, and `/local/summary`. Dormant
   findings still print in the full report, under a heading that says they need no
   action — that report is where "why does it think I have Apollo?" gets answered.

2. The console's conflicts card hardcoded "Another game-streaming server is
   **running** on this machine" regardless of what was found, so a dormant leftover
   was announced as a running server. It now says "active", and each entry names
   the observation — `Sunshine (running)`, `Apollo (starts automatically)`.

3. "The exclusive screen never times out going back to re-enabling the display."
   `isolate_displays_ccd` deactivates the operator's panels and hands the
   pre-isolate topology to the caller, which restores it at teardown — but that
   snapshot is PROCESS MEMORY, and Windows deliberately never saves the isolated
   topology to the CCD database. So a host that crashed, was killed, or was stopped
   mid-session left the desk dark with nothing in the product to undo it. There was
   one startup recovery leg already, but only for the EXPERIMENTAL
   `pnp_disable_monitors` axis, which is off by default — the default Exclusive path
   had none. `isolate_journal` now marks what an isolate is about to switch off
   (before the apply, so dying mid-apply is covered), clears the mark on restore,
   and force-EXTENDs at host startup if a mark survived. EXTEND rather than
   replaying the saved blob: the blob pins the virtual display's target id, which
   dies with the crashed host, so a replay would mostly fail BAD_CONFIGURATION into
   the very same backstop `restore_displays_ccd` already keeps — and EXTEND stays
   correct across a reboot, where saved ids would be stale.

Pressing guide/Steam/QAM collided with the client device's own shell: iOS 26
opens its Game Overlay for the Home press (no app opt-out until iOS 27 makes
it a user setting), and a Gaming-Mode client opened BOTH Steam overlays for
one press — the local one covering the stream.

Two cross-client tier-P settings, zero wire changes:

- system_buttons (auto|forward|local): raw guide+misc1 passthrough. Auto
  forwards everywhere EXCEPT under gamescope, where SteamOS reacts to the
  same physical press no matter what.
- guide_gesture (auto|on|off): hold Select ALONE ~350ms sends the HOST's
  guide, down until release — held on, that's the host's long-press, which
  opens a Gaming-Mode host's QAM for regular pads. A Select tap is delivered
  on release with its up TAP_PRESS (50ms) behind, because per-transition
  sends fold into seq'd GamepadState snapshots and a back-to-back pair can
  coalesce into no press at all. A Select inside a combo (the escape chord)
  passes through untouched. Auto arms it only where the raw press can't
  reach the host cleanly: gamescope, iOS/iPadOS, tvOS.

The same SelectGesture rules live in pf-client-core (pure state machine +
unit tests), the Apple client (mask-diff adaptation in GamepadCapture), and
Android's GamepadRouter. Settings rows on every surface (GTK, WinUI,
console UI, Decky, Apple x2, Android x2) with profile plumbing throughout.

punktfunk-session grows a control socket
($XDG_RUNTIME_DIR[/app/$FLATPAK_ID]/punktfunk-session-ctl.sock — the one
runtime path a flatpak and the host see identically): 'guide'/'qam' verbs
inject synthetic taps. The Decky panel gains a Host menus section (visible
while the client runs) whose buttons press the host's Steam/QAM and close
the local menu so the host's shows through.

iOS 27's GCControllerHomeButtonSettingsManager deep-link is a TODO (the
class needs the Xcode 27 SDK to compile). Docs: input, client-settings,
steam-deck. Design: punktfunk-planning design/system-buttons-routing.md.

An adversarial review of this branch found a regression I introduced, plus three smaller
defects. All four are fixed here, each verified on .21.

**The regression.** `mergeHosts` names a host by its record's stable id, and `hosts list --json`
always emits one (`KnownHosts::load` mints ids for every record). So a launch always went out as
`punktfunk launch <uuid>` → `ConnectPlan::for_host` → `HostTarget::from(&KnownHost)`, which
copies the address stored ON THE RECORD. Meanwhile the panel deliberately renders the LIVE
advert's address. Nothing on a Deck ever writes a moved address back — `discover` and
`hosts list` are both reads, and only the desktop shells' hosts pages update one.

So after any DHCP move the row read "online" at the new address and every press dialled the old
one: a 15 s dead connect, or — if a MAC had ever been learned — a black Steam "game" for the
full 90 s wake budget. Proven with a stub session binary: `launch abc-123` emitted
`--connect 10.0.0.5:9777` for a host answering at `10.0.0.99`.

This worked on origin/main, which dialled `toHost(v).host` — the advert's address. The fix
restores that without giving up stable ids: `hosts add <new-addr> --fp <known-fp>` now MOVES the
matching record instead of filing a second one (the fingerprint is the identity — this is the
same rule that makes the verb idempotent), and the panel re-points a host it can see has moved
before launching it. Verified: `moved 10.0.0.5:9777 to 10.0.0.99:9777`, one record still, and
`launch abc-123` then emits `--connect 10.0.0.99:9777`.

**"No hosts yet" was also how a missing client looked.** `_cli_argv()` returning None becomes
`client-unavailable`, which the panel dropped on the floor — so a Deck with no client installed
was told its network was empty, under a button that launches the client that isn't there. It now
says which of the two it is.

**The browse worker never exited on a quiet LAN.** `discover_for` drops the receiver and the
doc claimed that stops the thread. It does not: the worker parks in `recv()`, and the arms that
ignore an event (`SearchStarted`, `ServiceFound`, `SearchStopped`, a v6-only advert) never touch
the sender, so on a LAN with no Punktfunk host nothing ever wakes it. Harmless today because the
only caller is a short-lived CLI process, but the function invites in-process use, where it would
leak a thread and an mDNS daemon per call. Now polled with a 250 ms tick and a check at the top
of the loop. Verified: ten back-to-back browses settle back to the baseline thread count.

**A `pair=optional` host was recorded as paired.** Every unsaved host now goes through the trust
sheet (it has no pin, so it cannot stream without one), but the sheet's only non-PIN action ran
`--request-access`, which persists `paired: true` on Ready. An optional host admits anyone who
pins its identity — there is no operator decision, so nothing was approved and the same box read
"paired" here and "trusted" in the desktop client. Such a host now gets **Connect** instead,
which pins and streams without claiming an approval, and the "approve this Deck" toast is no
longer shown to someone who has nobody to ask.

Also: `PF_CLIENT_BIN` was the one launch-option value never validated — a client installed under
a path with a space would split Steam's tokenizer.

enricobuehler 414380fc9e fix(cli): discover reads the host store without writing to it
`KnownHosts::load()` mints a stable id for any record that lacks one and SAVES it — which makes
it a write, and `discover` was calling it purely to annotate what the browse found with
saved/paired. It never hands those ids back to anyone.

That matters because the Decky panel issues `discover` and `hosts list` together, in parallel.
Against a store written before ids existed, both processes read it, both mint DIFFERENT ids for
the same record, and both save. Whichever loses the race has already handed its ids to its
caller — so the panel could draw a row whose host reference no longer resolves, and pressing it
would exit 5 ("no saved host matches") until the next refresh settled things.

`KnownHosts::read()` is `load` without the mint: the store exactly as it is on disk. `discover`
uses it; every caller that dials a host by id still uses `load`, so ids are still minted the
first time anything needs one.

Verified on a fixture store with no ids: `punktfunk discover` leaves it byte-identical, and a
following `punktfunk hosts list` mints as before.

BREAKING (C header only): constants such as MAX_PADS, TAG_LEN, ABI_VERSION,
INPUT_MAGIC and the whole BTN_/AXIS_ family are now PUNKTFUNK_-prefixed.

cbindgen emits a bare #define per `pub const`, so those names landed in the
namespace of every C program that includes the header. The rename table already
said this was the rule and already carried the handful someone had noticed —
and its own comment spells out why it matters: a clashing #define silently
takes the last definition rather than failing to compile, so the failure mode
is a wrong value, not a build error. This is the remaining 149.

Associated constants are deliberately left alone. cbindgen already qualifies
those with their type name, which is the very property whose absence makes a
bare MAX_PADS dangerous — they are namespaced, just not by us.

Nothing in this repository consumed the unprefixed spellings except one Swift
test, which sat next to lines already using the prefixed form because its
constant happened never to have been added to the table; it is updated here.
The C harness links and runs against the regenerated header.

Scheduled deliberately: the sweep flagged this for a release boundary, and
0.24.0 has shipped. External C embedders using the old spellings must add the
prefix; there is no silent breakage, since the old names simply stop existing.
