enricobuehlerandClaude Opus 5 17eb8100a3 fix(pf-capture): portal teardown, observable death, one negotiation resolver (sweep 2.1–2.3)
**2.1 (L1) — the portal thread leaked a live screencast session.** It parked on
`future::pending()` and `Drop` stopped only the PipeWire thread, so every dropped portal capturer
permanently leaked a thread + a 2-worker tokio runtime + a zbus connection — and because dropping
that connection is what ends the compositor's cast (ashpd's `Session` has no `Drop`), the
COMPOSITOR-side session leaked too. GameStream drops the pooled capturer on every HDR↔SDR
reconnect flip and opens a fresh one, so the sessions accumulated: exactly the "second conflicting
screencast" the pooling exists to prevent. Both portal threads now park on a `oneshot::Receiver`
and `PortalSession::drop` fires it, then waits — BOUNDED (750 ms, then detach with a warning) —
for a completion signal the thread sends after its runtime has been dropped. Bounded because
teardown runs on the session path and the thread may be inside a D-Bus round-trip: an unbounded
`join()` there would hang the host rather than leak. Every early-return path in `open` drops the
session too, so a failed PipeWire spawn no longer strands a fresh cast.

**2.2 (L2) — a dead capturer was pooled forever.** All three of the portal backend's terminal
states are sticky and observable only by consuming a frame, and `Capturer` exposed no health
predicate, so GameStream re-pooled unconditionally — after `result` was already an `Err`. One
zerocopy-worker death or one compositor restart therefore wedged GameStream portal video at 10 s
per reconnect attempt, permanently (that path has no rebuild closure). Adds
`Capturer::is_alive()` (default `true`), implemented for `PortalCapturer` as
`!broken && streaming && !thread.is_finished()` — the third term catches a dead PipeWire thread,
which is otherwise indistinguishable from an idle desktop. A static desktop stays `Streaming`, so
an idle-but-healthy capture is never reported dead. The host re-pools only on
`result.is_ok() && capturer.is_alive()` and logs which of the two retired it. Both halves ship
together: either alone leaves the wedge reachable.

**2.3 (L3/F1) — a "VAAPI" downgrade latch was really a global zero-copy kill switch.**
`spawn_pipewire` hand-mirrored the thread's `vaapi_passthrough` decision and the copy omitted
`raw_dmabuf_import_disabled`, so once that latch fired the capturer still believed it had made the
passthrough offer while the thread had already fallen back — and its timeout branch then latched a
downgrade for an offer nobody made. That downgrade was `note_vaapi_dmabuf_failed`, which fed
`pf_zerocopy::enabled()`, so ONE failed negotiation dropped every later session on the host — the
NVENC EGL→CUDA path included — to CPU capture until restart. And since the raw-passthrough offer
is also the PyroWave one on ANY vendor, a single PyroWave negotiation timeout was enough to do it
on an NVIDIA box.

Two fixes, both structural:
  - `negotiation_plan(NegotiationInputs) -> NegotiationPlan` is now the ONE resolver, consumed by
    the thread AND by `spawn_pipewire` — the mirror is deleted, not re-synced (WP7.6's shape), so
    the drift class is unrepresentable. It is pure (every env/latch read is an input), which is
    what makes it testable; the runtime-dependent half stays a method (`want_dmabuf` needs the
    modifier list the importer's construction actually yielded). The redundant `importer.is_none()`
    term goes: `build_importer` already excludes the passthrough, and that term is what made the
    decision look impure enough to "need" a mirror. `PUNKTFUNK_FORCE_SHM` was ALSO read in both
    places; now once.
  - the capture-side downgrade becomes `pf_zerocopy::note_raw_dmabuf_negotiation_failed`, which
    latches `RAW_DMABUF_DISABLED` — gating only the raw-passthrough decision. `enabled()` is now
    the env var alone, and `VAAPI_DMABUF_FAILED` is deleted.

Also (L13, needed by 2.3's plan inputs): `PUNKTFUNK_PIPEWIRE_NV12` honoured only the exact string
`"0"`, so `"0 "` or `"false"` read as force-ON — the bug class of ed525c4c. pf-host-config's
explicit-off grammar is now exported as `env_on()` and the four in-crate copies (`PUNKTFUNK_
ZEROCOPY`/`_10BIT`/`_444`/`_CHACHA20`) plus this new caller share it.

7 new tests pin the four invariants that were prose-only comments, plus the latch property that
made the mirror wrong. pf-capture 13/13; workspace clippy --all-targets clean on Linux and on
x86_64-pc-windows-msvc. On-glass validation of 2.1/2.2/2.3 is owed (sweep Phase 7.1).

enricobuehlerandClaude Opus 5 54a37aeb46 docs(pf-capture): truth pass over comments, docs and log strings (sweep Phase 1)
Every item here is prose that actively misdirects a maintainer or an operator. Landing it before
the defect fixes means those diffs get reviewed against accurate comments.

1.1 (X5) — split two merged doc blocks that documented the item ABOVE them: `hdr_meta`'s whole
contract was glued onto `fn cursor()` in lib.rs (leaving `hdr_meta` undocumented), and
`hdr_p010_selftest_at`'s was glued onto `hdr_p010_convert_bars_on_luid` in dxgi.rs. rustdoc for
the trait's central HDR contract was simply wrong.

1.2 (L9 doc half) — the `Capturer` trait doc advertised a "bounded drop-oldest channel". The
Linux portal's `sync_channel(8)` + `try_send` is drop-NEWEST: under a consumer stall the arriving
frame is discarded and the encoder gets the stalest queued one. Say so. (Phase 2.6 changes the
behaviour; this commit only stops the doc from lying about today's code.)

1.3 — delete the DONT_FIXATE claim from the dmabuf offer comment. `build_dmabuf_format` emits a
plain MANDATORY `ChoiceEnum::Enum` and `param_changed` re-emits nothing, so there is no two-step
DMA-BUF handshake here; libspa 0.9's `ChoiceFlags` cannot even express DONT_FIXATE. Recorded as a
real follow-up instead of an implemented thing.

1.4 — `mainloop.run()` no longer "blocks until process exit": the quit channel attached above it
stops the loop from `PortalCapturer::drop`.

1.5 (L11) — the 6-arm negotiation log ladder told a fully zero-copy PyroWave session "VAAPI
encode with the CPU capture path — zero-copy was disabled", one line after logging that it had
advertised the PyroWave device's dmabuf modifiers: the passthrough arm was gated on
`pyrowave_modifiers.is_empty()`, so the pyrowave case fell through to the CPU warning. Ungate it;
the CPU-path arm is now reachable only when no dmabuf is advertised at all, which is what it
claims. Its parenthetical also gains the third real cause (the session asked for CPU frames).
Control-flow-neutral for every other combination.

1.6 (W13) — `kick_dwm_compose` claimed a "sub-millisecond" round trip while its
cursor-on-a-sibling-display branch sleeps 35 ms on the CALLER's thread. State the cost on the
function and at both call sites, including which one is on the live frame path.

1.7 (W16) — DDA-era residue, DDA having been removed:
  - retarget the win32u hook's rationale + all four log strings: its job is no longer "keep DDA on
    one adapter" but "keep the virtual display on the adapter SET_RENDER_ADAPTER pinned" (a DXGI
    reparent surfaces as the driver's TEX_FAIL render-adapter mismatch). The hook stays installed.
  - the per-monitor-v2 DPI awareness rationale likewise: not DuplicateOutput1's E_ACCESSDENIED any
    more, but keeping cursor/window coordinates in the PHYSICAL pixels the host's CCD geometry
    (`source_desktop_rect`, `desktop_bounds`) is already in.
  - `HYBRID_HOOK_HITS` was write-only. Surface it as `hybrid_hook_hits()` on the IDD-push open
    line, which is the first point where DXGI has actually been exercised — the patch-readback
    check proves the bytes landed, only this proves DXGI reaches the export.
  - delete `hdr_p010_selftest()`: an unreachable 64×64 wrapper (main.rs calls
    `hdr_p010_selftest_at`); its description moves onto the function that survives.
  - `VideoConverter`'s docs promised a P010/BT.2020 output and a live scRGB input path. It pins
    `YCBCR_STUDIO_G22_LEFT_P709` unconditionally and its only caller always passes
    `scrgb_input: false`.

1.8 (X7) — the native handshake's 4:4:4 gate comment stated the OPPOSITE of what
`pf_capture::capturer_supports_444` returns on Windows ("delivers subsampled NV12/P010 today, so
it returns false there" — it forwards `resolved_backend_ingests_rgb_444()` and the IDD ring passes
BGRA through for an SDR 4:4:4 session).

No `.rs` behaviour delta: comments, doc comments and log strings, plus 1.5's control-flow-neutral
ladder and 1.7's counter accessor. Linux tests 6/6; clippy --all-targets clean on both targets.

enricobuehlerandClaude Opus 5 6a2a153c0b chore(pf-capture): make the crate verifiable — Windows CI lint + two denies (sweep Phase 0)
Gate for the rest of design/pf-capture-sweep.md: today half this crate is compiled by no CI job
at all, so the Windows-side findings can't even be type-checked.

0.1 (X1) — windows-host.yml lints `-p pf-capture --all-targets`. The host lint above it builds
pf-capture only as a DEPENDENCY, so its `#[cfg(test)]` modules were never compiled anywhere: the
5 StallWatch tests, the DXGI HDR self-tests and the cursor-conversion tables were dead code in
CI. The workflow's own comment already diagnosed this blind spot and fixed it for pf-encode;
pf-capture never got the same treatment. No features on this crate, so no feature juggling and
no extra dep tree.

0.2 (X2) — `#![deny(unsafe_op_in_unsafe_fn)]` beside the existing
`deny(clippy::undocumented_unsafe_blocks)`. The crate declares "every unsafe block carries a
SAFETY proof; enforce it" in ten file headers, but in edition 2021 that lint has nothing to fire
on inside an `unsafe fn` — so the hardest FFI in the crate was exempt from its own program: the
ring/slot construction, the fence signal, the blend scratch, and every D3D converter ctor/convert.
119 operations across 16 functions now carry a proof. `shared_object_sa` loses its `unsafe`
marker instead (it states no precondition — only its RESULT is a raw pointer, which is the
caller's business).

0.3 (X4) — drop the crate-wide `#![allow(dead_code)]`. Verified: zero warnings on either target
without it, so it was hiding nothing the lint can see (W16's dead items are `pub`/written-once,
so they need Phase 1.7's deletion instead).

No behaviour change: only lint attributes, `unsafe { }` scoping and comments.

Linux `cargo test -p pf-capture` 6/6, clippy --all-targets clean on both targets (Windows
verified by cross-checking x86_64-pc-windows-msvc locally).

0.18.0 regression: UAC consent and Winlogon (lock/logon) stopped appearing
in streams. The cursor channel's IddCx hardware-cursor declare — re-issued
by the driver on every swap-chain assign — keeps the path out of the OS's
software-cursor mode, which is the only mode the secure desktop renders
through; DWM then never presents UAC/Winlogon into our swap-chain and the
stream repeats the last normal-desktop frame for the whole interaction.

The GDI cursor poller now classifies the input desktop on its reattach
cadence (UOI_NAME != Default = secure, 250 ms cadence instead of 2 s), and
the capturer edge-triggers the existing-but-unused proto-v6
IOCTL_SET_CURSOR_FORWARD flip: OFF at secure entry (the driver stops its
per-assign re-declare; the host facade forces the same-mode re-commit that
actualises the software-cursor default, under the vdisplay manager lock via
the new force_recommit()), back ON at dismissal for channel sessions.
Channel-session open resets the driver's persisted desired state to ON so
a session that died mid-secure-desktop can't leave the next one adopting
UNdeclared (the §8.6 cross-session composite trap); orderly teardown does
the same. The flip closure is built for every Windows session — a
channel-less session can reuse a driver monitor whose earlier-session
cursor worker still re-declares, and NOT_FOUND from never-declared targets
is ignored.

enricobuehlerandClaude Opus 4.8 d5ae8dcc3e feat(capture): gamescope cursor via XFixes shape + QueryPointer position (Phase C)
gamescope excludes its pointer from the PipeWire node it feeds us and can't embed
one either (`set_hw_cursor` is inert), so every gamescope stream was cursorless.
Read the pointer from gamescope's nested Xwayland instead — XFixesGetCursorImage
for shape/hotspot/visibility, core QueryPointer for position — and publish a
CursorOverlay into the capturer's existing `cursor_live` slot, so the encoder
blend composites it into the video exactly like the SPA_META_Cursor path.

- pf-capture/src/linux/xfixes_cursor.rs (new): the XFixes reader. Connects to
  EVERY nested Xwayland (Gaming Mode runs one per --xwayland-count) and follows
  the focused one each tick (the display whose pointer moves), reading that
  display's own cursor shape. Un-premultiplies ARGB -> straight RGBA. Drop stops
  the thread.
- Capturer::attach_gamescope_cursor + the PortalCapturer override spawn it into
  the same `cursor_live` slot; pf_vdisplay::gamescope_xwayland_cursor_targets
  discovers the (DISPLAY, XAUTHORITY) pairs via the GAMESCOPE_WAYLAND_DISPLAY scan.
- host: SessionPlan.gamescope_cursor (set from the compositor at both resolve
  sites AND on a mid-stream Desktop->Gaming switch); the blend gate now builds the
  encoder blend for gamescope; a sibling composite arm attaches capturer.cursor()
  per tick for capture-mode clients (no channel needed). native NV12 is disabled
  for these sessions — that encode path can't blend the cursor (it assumes
  gamescope embeds the pointer), so we capture RGB and route to the proven CUDA
  VkSlotBlend / compute-CSC blend.
- the pipewire thread no longer clobbers `cursor_live` with None on a buffer that
  carries no SPA_META_Cursor (gamescope) — that raced the XFixes writer and
  strobed the composited pointer on/off.

On-glass (home-bazzite-2, RTX 5070 Ti, Gaming Mode): cursor visible + steady in
Big Picture and CS2 menus, follows focus between the two Xwaylands, hidden in-game.

enricobuehlerandClaude Fable 5 af87549052 fix(linux/vdisplay): KWin virtual outputs stream above 60 Hz via sacrificial-birth renegotiation
KWin's ScreenCastStream builds its PipeWire format offer — including the
maxFramerate cap it actively throttles delivery to — ONCE at stream
creation, when the virtual output sits at its hardcoded birth 60 Hz. A
kscreen custom-mode change afterwards updates the OUTPUT (readback says
240) but never the offer, so every consumer negotiates max=60 and the
stream delivers 60 (pw-dump-verified on KWin 6.6.4). The only path that
rebuilds the offer is the stream's own resize handling: a source SIZE
change while recording re-runs buildFormats — picking up the output's
current refresh — and renegotiates the live stream.

So above 60 Hz, birth the output at a sacrificial height (+16), then
install + select the real WxH@hz custom mode: the first frame recorded
after the consumer connects triggers KWin's resize path, which renegotiates
the live stream to WxH@hz. The capturer holds (requeues) buffers until the
negotiated size matches — new expect_exact_dims plumbing VirtualOutput →
registry (fresh creates only) → open_virtual_output → a self-disarming
gate in the process callback — bounded by a 3 s deadline that accepts the
producer's dims rather than wedging the session into the first-frame
retry loop. set_custom_refresh reads back the full active mode; a size
reject (pre-6.6 KWin) recreates plain at the real size @60.

Every kscreen operation now addresses the output by its NUMERIC id,
resolved by matching the managed name-prefix AND the just-created birth
size (newest id wins): a mode-switch supersede reuses the per-slot output
NAME (deliberately, for KWin's per-name config persistence) while the
superseded sibling is still alive, and name addressing hit the FIRST
match = the OLD output — on-glass that resized the live session's display
out from under it (wrong-res/black), read the old output back as 'mode
applied', and set the old output primary while the replacement starved at
its birth mode.

enricobuehlerandClaude Opus 4.8 0af280a793 feat(windows/capture): host-side cursor compositing for the capture model — the deterministic fix
Root cause, proven on-glass across five driver builds: a declared IddCx
hardware cursor is IRREVOCABLE. There is no un-declare DDI, the
empty-caps re-setup is rejected INVALID_PARAMETER, and after a
successful same-mode re-commit with the driver's re-declare provably
suppressed (sticky per-target flag, zero re-setups logged) DWM still
never composites the software cursor back into the monitor's frames.
Every DWM-based composite flip is therefore unfixable.

The composite (capture) model is now implemented in OUR pipeline:
- the driver keeps its hardware cursor declared for the session's whole
  life (the state that works) — frames stay pointer-free always;
- in composite mode try_consume routes the conversion through a blend
  scratch: slot copy + one alpha-blended quad of the GDI poller's shape
  at its polled position (CursorBlendPass — fullscreen-triangle VS with
  viewport placement, straight-alpha PS, sRGB→linear for FP16/HDR
  rings), covering all four convert paths (NV12, 4:4:4 copy, P010,
  PyroWave) GPU-side under the slot's keyed mutex;
- pointer-only motion produces no driver publish (declared hw cursor),
  so try_consume REGENERATES from the last slot whenever the polled
  cursor state changes — the cursor moves on a static desktop at tick
  rate, without faking freshness for the stall/death watchdogs;
- set_cursor_forward becomes purely host-internal state; the
  SET_CURSOR_FORWARD IOCTL machinery is no longer used by the host
  (driver keeps it, dormant) and its sender plumbing is removed.

enricobuehlerandClaude Opus 4.8 92761813a9 feat(core+host+driver+client): mid-stream cursor-render flip — host composites in the capture model
The cursor channel excluded the host pointer from the video for the
whole session, but the client only draws it under the DESKTOP mouse
model — flipping ⌃⌥⇧M to capture mid-stream left the session
pointer-blind (user-found). The fix makes render ownership LIVE state:

- wire: CursorRenderMode 0x51 (client→host, control stream) —
  client_draws: true = desktop model (host excludes + forwards),
  false = capture model / released (host composites, full fidelity —
  DWM on Windows incl. real XOR inversion, encoder blend on Linux).
  Sessions start client_draws=true (the pre-message behavior).
- host: control task stores the flag; the encode loop edge-detects it —
  forwarding + frame.cursor strip while the client draws, quiet
  forwarder + overlay-into-blend while composited. SessionPlan now
  grants blend CAPABILITY wherever the capture has a pointer (dropping
  the !cursor_forward gate) so the composite side needs no encoder
  rebuild; per-tick frame.cursor decides what is drawn.
- Windows: Capturer::set_cursor_forward → retained
  IOCTL_SET_CURSOR_FORWARD sender (proto v6) → driver (un)declares the
  IddCx hardware cursor on the LIVE monitor. Un-declare re-issues the
  setup with EMPTY caps (candidate mechanism — the DDI has no
  documented un-setup); resetup-on-commit is skipped while off, so a
  mode commit's software-cursor default is the fallback path. Failure
  against a pre-v6 driver logs and keeps declared-at-ADD behavior.
- SDL client: one edge-detected reconciler at the cursor pump site —
  desktop-active = client draws; capture model or released = host
  composites. Covers the chord, the M3 auto-flip, and engage/release.
- C ABI v12: punktfunk_connection_set_cursor_render (additive; wire
  version unchanged — pre-§8 hosts ignore the unknown message type).

enricobuehlerandClaude Fable 5 3a34440a6b feat(windows): IddCx hardware-cursor channel — remote-desktop sweep M2c
Brings the cursor channel to Windows hosts. The pf-vdisplay driver
declares an IddCx hardware cursor for sessions that negotiated
cursor-forward — DWM then EXCLUDES the pointer from the IDD frame and
delivers shape/position out-of-band, into the same CursorOverlay →
forwarder → wire → client pipeline the Linux portal path uses.

- pf-driver-proto v5 (additive, host floor stays 3): AddRequest's spare
  tail becomes hw_cursor (same size/offsets); IOCTL_SET_CURSOR_CHANNEL
  delivers a host-created CursorShm section (64-byte seqlock header +
  256² shape buffer, layout pinned + tested). No event crosses the
  boundary — the host polls at encode-tick pace.
- driver: wdk-iddcx grows the two cursor DDI wrappers; a per-monitor
  cursor worker (event wait → QueryHardwareCursor → seqlock publish)
  starts only when BOTH the ADD asked and the channel arrived, so a
  failed delivery leaves DWM compositing as today. Shape bytes ship raw
  (BGRA/masked + pitch); the host converts.
- host: the section rides the existing sealed-channel broker (least-
  privilege dup, remote reap on failure); IddPushCapturer::cursor()
  seqlock-reads → CursorOverlay (BGRA→RGBA, masked-color approximation,
  desktop→frame origin shift, per-shape conversion cache). New
  Capturer::cursor() trait hook — the encode loop prefers it over the
  frame-attached overlay because hardware-cursor moves produce NO new
  frame on a static desktop. hw_cursor survives the re-arrival resize
  (carried on the manager's Monitor).
- negotiation: cursor_forward grows the Windows arm (client cap ∧
  driver proto ≥ 5, probed once via the control device); SessionPlan
  carries cursor_forward → OutputFormat.hw_cursor.
- drive-by: wdk-probe's two pre-existing same-type casts (clippy) and
  pf-vdisplay's stale spike-test refs (crate::win_display moved to
  pf-win-display; tracing-subscriber was never a dep) repaired.

Verified: proto tests on Mac AND MSVC (15/15 incl. the CursorShm
layout pin); clippy -D warnings for proto/frame/capture/vdisplay/host
on Linux (.21) and native Windows (.173); the DRIVER workspace clippy
-D warnings green against the real WDK 10.0.26100 bindgen (DDI names,
enum variants and IDARG layouts all bind). On-box driver deploy +
on-glass validation follow.

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

enricobuehlerandClaude Opus 4.8 46d09ed973 fix(host/linux): stop burning retry budget on doomed pipeline builds
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).

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.

drift — six files were not clean under the pinned 1.96.0 toolchain, so

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.

enricobuehlerandClaude Opus 4.8 ebd9967547 feat(pyrowave): Windows host encoder — separate-plane zero-copy D3D11→Vulkan
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.

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.

enricobuehlerandClaude Opus 4.8 09849906e9 Merge perf/first-frame-latency: driver proto v4 + first-frame/resize latency (P0-P2)
Brings the first-frame-latency branch (P0.1 transition tracing, P1.1/P1.2
Welcome-time display prep, P2 in-place resize; pf-driver-proto v3 -> v4 with
IOCTL_UPDATE_MODES) onto current main. The branch predates the W6.2/W7 splits,
so git's rename detection carried most of it into the moved crates
(pf-capture idd_push, pf-vdisplay manager/pf_vdisplay, pf-win-display,
pf-driver-proto, the driver workspace) and the punktfunk1.rs remainder was
re-homed by hand:

- native/handshake.rs: welcome/start trace marks + the Welcome-time display
  prep spawn (the prep thread BECOMES the stream thread; hand-off via a
  SyncSender<SessionContext>). negotiate() gains bringup/quit/stop and returns
  the PrepHandle.
- native.rs: bringup/resize_ms creation + the stop/quit flags hoisted BEFORE
  the handshake (the close watcher splits: flags pre-handshake, lifecycle
  events post-handshake where `hello` exists); punch_done stamp; the data
  plane adopts the prep thread's result or builds inline.
- native/stream.rs: SessionContext/SendStats carry the trace; send_loop
  finishes it on the first video packet; the resize path gains the in-place
  fast path (try_inplace_resize) with the full rebuild as fallback, restructured
  so both share the post-rebuild bookkeeping; prepare_display/PreparedDisplay/
  PrepHandle; build_pipeline(+retry) thread the stage marks.
- session_status/mgmt: ttff_ms + last_resize_ms per session (union with the
  lifecycle-events fields main added to the same spots).
- pf-capture: Capturer gains capture_target_id() + resize_output() defaults.
- pf-vdisplay manager: perf's faster activation poll (60x50ms) + the settle
  floor before the PnP sweep, on main's knobs/no-trait shape.

Also: packaging/windows/build-gamepad-drivers.ps1 is ASCII again (an em-dash
from the pf-mouse work tripped windows-host.yml's locale-safety gate on main).

enricobuehlerandClaude Opus 4.8 94ca4041ca refactor(host/W6.2): extract the frame-capture backends into the pf-capture crate
capture/linux (PipeWire portal) + capture/windows (IDD direct-push: dxgi
mechanics, idd_push + submodules, synthetic_nv12) + pwinit move into
crates/pf-capture behind the Capturer trait + synthetic sources (plan §W6).
The crate speaks pf-frame (CapturedFrame/PixelFormat + the DXGI identity),
pf-zerocopy (CUDA import), and the pf-win-display leaves, and NEVER pf-encode —
the capture->encode edge is one-way. This completes the deliberate capture/encode
crate split (the invasive path the plan had merged into one pf-media): capture
and encode are now separate subsystem crates sharing only pf-frame.

Four seams keep the capturer off the orchestrator:
- VirtualOutput is EXPLODED into primitives (remote_fd/node_id/preferred_mode/
  keepalive) by the host facade, so pf-capture never depends on the vdisplay type;
- FrameChannelSender: the sealed-channel delivery is a Send+Sync closure the host
  facade builds from the pf-vdisplay control device + send_frame_channel IOCTL and
  hands in; ChannelBroker holds the closure instead of the control HANDLE (the
  whole-desktop handle-duplication security boundary is byte-for-byte unchanged);
- console_session_mismatch + desktop_bounds live in pf-win-display (leaf peers);
- pwinit moves here (audio caller -> pf_capture::pwinit).

The host keeps capture.rs as a thin BRIDGE: it re-exports the vocabulary + capturer
types (every crate::capture::* path is unchanged) and keeps open_portal_monitor /
capture_virtual_output, which resolve the ZeroCopyPolicy + FrameChannelSender and
call into pf-capture. verify_is_wudfhost + install_gpu_pref_hook are re-exported
(the gamepad-channel bootstrap + the main.rs subcommand consume them).

Co-developed: the resident-HID-mouse compose-kick hook (HID_COMPOSE_KICK + the
HID-first cursor kick + _display_wake) rides this commit into pf-capture; the host
mouse_windows registration side lands separately on top.

Verified: Linux clippy -D warnings (pf-capture + host nvenc,vulkan-encode,pyrowave
--all-targets) + host tests 299/299; Windows clippy -D warnings (pf-capture
--all-targets + host nvenc,amf-qsv --all-targets) Finished exit 0.
