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
call sites — the listing was fixed during implementation, this one wasn't.

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

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

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.

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
rendered dark-on-dark. Tailwind derives both utilities from one token, so the

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.

The ~80% of every plugin that was copy-pasted (rom-manager ↔ playnite),
extracted as one Effect-v4 package:
- runtime: definePluginKit — async-main boundary hiding a ManagedRuntime
(two-effect-instances discipline), signal-driven interruption with a
bounded shutdown grace
- config: Schema-driven raw round-trip (defaults only in the Schema via
withDecodingDefaultKey + encodingStrategy omit; file stays authored-shape),
atomic writes, world-writable refusal, changes stream
- cache-store: disposable derived state, corrupt→empty, write-through
- reconcile: kit-owned provider wire schemas + typed client over the
skew-safe untyped pf.request seam
- sync-engine: generic poll/watch/debounce/single-flight-coalesce/
fingerprint-skip engine with a status PubSub (the SSE feed)
- 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

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

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.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
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
`session` before `pending`, and fields drop in declaration order).

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

The expanded island's height was underused. Bottom region is now the

Re-lands the island rebuild: a concurrent session's pull-rebase reordered the
pick against the canvas-previews commit and the pre-rebuild file content won;
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
especially), reading as one colliding block; ~46 chars/line also measures
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
CAMetalDisplayLink vends from the layer's CURRENT config, and the layer starts
at drawableSize 0 (never tracks bounds; the sublayer isn't even laid out when
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.

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.

rpmbuild reported "bogus date in %changelog: Thu Jul 17 2026 ... - 0.0.1-3"
among its errors on the Fedora builds. 2026-07-17 was a Friday. The other two

Surfaced underneath the pf-capture compile failure in the same job, so it
would have become the next rpm blocker once that was fixed rather than
showing up on its own.

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
drift — six files were not clean under the pinned 1.96.0 toolchain, so
`cargo fmt --all --check` (ci.yml "Format") is red on main. Pure whitespace/
wrapping from `cargo fmt --all`; no semantic change.

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

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.

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)
- install: host cert is punktfunk-host-windows_<ver>.cer, not ..._setup.cer
- configuration: GPU_PRIORITY_CLASS default is auto; 10BIT/444 are default-on
- how-it-works/index: GameStream/Moonlight is opt-in (--gamestream)
- 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
- windows-host: note the optional bundled VB-CABLE virtual mic
- sway: PUNKTFUNK_COMPOSITOR=hyprland is a wlroots-family alias
- running-as-a-service: punktfunk-probe is a source-build-only dev tool

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

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
zero-copy tests. Owed: on-glass gamescope session (visual + dmon sm% check).

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
graph only compiled via feature unification).

--features nvenc,amf-qsv,qsv on build and clippy (static VPL dispatcher, no new
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
CMake-4 configure (observed on this runner on a clean target dir), so green
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).
Validated: .21 clippy -D warnings (punktfunk-host --features nvenc) against
the QSV-merged main; .133 Windows cargo check of pf-frame + punktfunk-host.

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;
re-verified at this base before landing.

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.
