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

Latency plan P0.4/P0.6: the fixed 250 ms advanced-color settle becomes a
25 ms poll of the CCD state (ceiling 250 ms, ring still sized FP16 from the
successful enable either way), and wait_for_attach waits on the driver's
frame-ready event (20 ms cap for the status-code polls) instead of a blind
20 ms sleep, which also sharpens the P0.1 stage stamps.

Latency plan P0.2/P0.3/P0.5 (design/first-frame-and-resize-latency.md):
- topology settle: the unconditional 1500 ms sleeps after create_monitor's
group-topology apply and re_add's reisolate become a 25 ms poll for the
committed state (active path + active mode == requested), ceiling 1500 ms —
worst case identical, typical case saves ~1.2-1.4 s on every fresh create
AND every mid-stream resize. The experimental pnp_disable_monitors sweep
keeps the full settle as its floor (it reads OTHER displays' active flags,
which the target-scoped wait doesn't verify).
- monitor departure: the fixed 400 ms REMOVE settles (re_add + both preempt
paths) become a 25 ms poll until the target leaves the active CCD set
(2 consecutive absent samples), ceiling 400 ms; the driver-side ghost-reap
ADD retry stays the backstop.
- activation ladder: 200 ms -> 50 ms sampling, same 3 s per-stage ceilings
and the same 3-stage structure.

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

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

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

Per plan §2.1: a self-contained stateful subsystem does not belong in the
audio trait facade. Move MicPump + its PumpTuning/PUMP_TUNING, the
drain_sleep/pump_thread loop, MIC_CHANNELS/MIC_QUEUE_CAP, and the six pump
unit tests out of audio.rs into audio/mic_pump.rs. audio.rs keeps the
AudioCapturer/VirtualMic traits, their open_* factories, and the sample
constants. Re-export via `pub use mic_pump::MicPump` so crate::audio::MicPump
stays byte-stable (only consumer: punktfunk1.rs). Pure code-move; verified
clippy 0/0 + 6/6 pump tests green on Linux (home-worker-5).

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

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

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

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

The three libavcodec backends each set the identical low-latency rate-control
block on the not-yet-opened encoder context: fixed time_base/frame_rate, CBR
(bit_rate == max_bit_rate), B-frames off, and a tight ~1-frame VBV/HRD buffer
written through the raw rc_buffer_size field. Move it once into
apply_low_latency_rc(&mut video, fps, bitrate_bps), and let the long VBV
rationale (why the tight buffer prevents high-motion bursts from overflowing
the send queue) live in one place instead of only in the NVENC path.
Each backend keeps the two genuinely per-backend calls around it: set_format
(pixel format differs) before, and gop_size after (NVENC's infinite/intra-
refresh wave vs the VAAPI/AMF i32::MAX). No behavior change — the field writes
are independent, so the slightly different max_b_frames/rc_buffer_size ordering
across backends is irrelevant. Folding the raw rc_buffer_size write into the
helper also removes the NVENC path's separate unsafe block. Drops the now-unused
ffmpeg::Rational import from all three.
Linux check + clippy green (0/0, nvenc,vulkan-encode,pyrowave) on RTX 5070 Ti;

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

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

The libavcodec paths (Linux NVENC, VAAPI, Windows QSV) each re-parsed
PUNKTFUNK_VBV_FRAMES locally in f32, duplicating and diverging in precision from
the f64 vbv_frames_env() helper the direct-NVENC/AMF paths already use. Now that
the helper lives in encode/codec.rs (532b313b), route all three through
crate::encode::vbv_frames_env(): one parse, one precision, no drift.
Behaviour-identical (same filter finite && > 0, same 1.0 default), f64 not f32.

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

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

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

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

marker_appears_while_held_and_vanishes_after drove the PROCESS-GLOBAL
registry and mutated XDG_RUNTIME_DIR mid-run — the punktfunk1
integration tests announce real sessions concurrently in the same test
process, so whichever registered first became the primary and the
marker carried its mode instead of the test's 2560x1440 (flaky on CI,
green locally by timing). The registry gains insert/remove methods and
rewrite() takes the target path, so the test now exercises the same
end-to-end lifecycle (atomic write, primary retention, session count,
removal) against a LOCAL registry and an explicit temp path — no env
mutation, no shared state. Production behavior unchanged.

The web console Dashboard read AppState.{streaming,launch,stream}, which only the
GameStream path writes, so a native punktfunk/1 session (the DEFAULT plane) showed
"Idle / no session" while actively streaming — only the Stats page (shared recorder)
reflected it. Add a plane-neutral per-session registry (session_status.rs) the native
video loop publishes to; /status now merges both planes, reports active_sessions, and
the Stop / Request-IDR buttons reach native sessions too (so surfacing them doesn't
leave dead buttons). LocalSummary (tray) gets the same fix.
Also on the management API:
- /host codecs derive from Codec::host_wire_caps() instead of a hardcoded
[H264,H265,AV1], so codecs the GPU can't encode no longer appear.
- ApiCodec serializes HEVC as "hevc" (matching the wire/SDP/stats label) so the same
codec reads identically across console pages.
- HostInfo.gamestream reports whether the GameStream planes run (--gamestream), so the
console can hide the Moonlight-only pairing UI on the native-only default host.
- StatsStatus.elapsed_ms (host-monotonic) so the capture timer doesn't mix host/browser
clocks.

The vhci-bound socket already set nodelay, but the server-side accepted
socket — the one carrying every URB reply back to the kernel — did not.
The wired single-interface device never tripped it, but the Puck's six
concurrent endpoint streams turn the request/response URB pattern into
classic write-write-read Nagle/delayed-ACK stalls: measured ~22 reports/s

Community-contributed round 5 of the Steam Controller 2 passthrough,
reviewed + verified. A Puck-captured pad now presents the dongle's real
seven-interface identity (CDC pair, four controller HID slots, management
HID) instead of relabelling its reports as a wired 1302 — Steam's Puck
feature dances (wireless_transport / esb/bond / 0xB4 slot status) get
capture-shaped answers, and the wired identity's canned replies are
corrected to the real captures (attribute count, string-attr framing,
0xF2 firmware info, bcdDevice nibble encoding).
- new wire pref 10 = SteamController2Puck (Hello/Welcome byte; older
peers degrade to Auto), selected by the Android capture link when the
transport is a dongle, or by VID/PID in the degraded InputDevice path
- TRITON_RDESC is now the captured numbered descriptor (mouse/keyboard
lizard collections + per-id vendor reports); unnumbered framing made
hidraw mangle feature report 2 and Steam eventually closed the device
- interrupt-IN now queues sparse reports (battery/RSSI/wireless edges)
instead of keeping latest-only, so a 250 Hz state packet can no longer
erase them before the USB/IP poll observes them; EP0 SET_REPORT is
split by wValue report type (OUTPUT parsed for rumble vs FEATURE)
- vendored usbip-sim: config attributes/max-power, IAD prefix + BOS
descriptor support, correct BCD minor.patch encoding (Deck's 0x0300/
0x0200 values are nibble-zero, so its bytes are unchanged), and
full-speed interrupt pacing in ms (was 8 kHz from the HS formula)
- Triton feedback is serviced at 1 kHz while an SC2 backend exists so
Steam's trackpad haptic writes reach the client unbatched

The Linux clippy leg has been red since 5249d31d (cursor-as-metadata):
that push was verified fmt-green but the -D warnings clippy step (which
only compiles the Linux/CUDA target) was not. Five findings:
- capture/linux/mod.rs: the spa_meta_bitmap field-read unsafe block had
no adjacent SAFETY comment (the preceding one documents the pointer
arithmetic block, not this deref).
- zerocopy/cuda.rs: the cuModuleGetFunction unsafe block's SAFETY comment
sat before the enclosing closure instead of adjacent to the block.
- zerocopy/cuda.rs: blend_argb/blend_yuv444/blend_nv12 tripped
too_many_arguments (9/7) — geometry+cursor-size+offset params that a
struct would only unpack at the call site; allow, matching the crate's
existing use of the attribute.
Unblocks the 0.12.0 release (main must be green before the tag).

game as-is; absent → run the local (e.g. multi-head gamescope) path.
- New stream_marker module: RAII Guard registered per session, refcounted
for concurrent clients, atomic (temp+rename) writes, injection-safe
single-quoted client name. POSIX-sh-sourceable KEY=value, namespaced
PF_STREAM_* keys, schema-versioned, additive-only.
- Hooked into serve_session so every exit path (disconnect, error,
panic-unwind) retracts the marker. File exists iff a stream is live.
Unblocks the downstream triple-head gamescope launch-wrapper use case.

Extends 56f9c8c4 (the Automatic-bitrate decode signal, core + Android) to the remaining
clients, so every platform caps Automatic at its real decoder limit instead of the network
link ceiling — the fix for a fast LAN feeding a slower hardware decoder.
- core/abi: punktfunk_connection_report_decode_us + _wants_decode_latency expose the
NativeClient methods to the C-ABI embedders (regenerated punktfunk_core.h, additive only).
- apple: PunktfunkConnection wrappers + Stage2Pipeline reports received→decoded from the
VideoToolbox decode-completion callback — every decoded frame, before the newest-wins ring
can drop the backlog. Stage-1 (AVSampleBufferDisplayLayer, no per-frame decode callback)
stays network-only; stage-2 is the metered path.
- windows/linux: the shared punktfunk-session client (pf-client-core) links core directly, so
it calls the NativeClient methods — report received→decoded from the pump, gated on
wants_decode_latency. Exact for the synchronous D3D11VA/software decode; received→submit
(still the decoder-input backpressure signal) for the async Vulkan-Video path.

The Automatic bitrate controller only reacted to network signals (loss, capture→received
OWD, FEC-unrecoverable frames, jump-to-live flush), so on a fast LAN feeding a slower
mobile HW decoder it slow-started straight to the link-probe ceiling and parked there —
backlogging frames inside the decoder, where those signals never register, and choking it.
Reported on a Snapdragon 8 Gen 1: Automatic pinned ~500 Mbps with unusable latency.
Feed the client's decode-stage latency (received→decoded) into the controller as a
first-class signal, symmetric with the existing OWD one: a rise over its rolling-min
baseline ends the slow-start climb and, sustained over two windows, backs the rate ×0.7
down to the real decode limit — so Automatic settles where the decoder keeps up.
- core/abr: on_window gains decode_mean_us; a decode_means rolling-min baseline +
DECODE_RISE_US (15 ms) fold a decode rise into the bad-window logic.
- core/client: per-frame report_decode_us accumulator, drained to a window mean by the
data-plane pump; wants_decode_latency() gate (Automatic, non-PyroWave) lets embedders
skip the measurement where it's ignored. Re-target log prints the driving signals.
- android/decode: report the decode stage on both the sync and async decode paths,
HUD-independent, measured from the AU leaving next_frame (so codec-input backpressure
is included) and excluding the vsync present wait.
Apple/Windows report_decode_us calls to follow.

gamescope draws its pointer on a hardware DRM cursor plane that never enters
the framebuffer feeding its PipeWire capture node, so captured frames arrive
cursorless. Rather than force the producer's Embedded full-frame composite,
request the pointer as PipeWire SPA_META_Cursor and composite it ourselves —
a ≤256×256 blit into the encoder-OWNED surface, never the compositor's
read-only dmabuf.
Capture (capture/linux/mod.rs, capture.rs):
- choose_cursor_mode() gates on available_cursor_modes(): Metadata > Embedded
> Hidden (defaults Embedded on query error — never silently lose the cursor).
Applied on both the plain and remote-desktop portal paths.
- build_cursor_meta_param() adds a SPA_PARAM_Meta pod requesting SPA_META_Cursor
(bitmap up to 256x256) to the connect params on every path.
- CursorState parses spa_meta_cursor (id 0 = hidden; position - hotspot; bitmap
re-read only when bitmap_offset != 0), normalizing RGBA/BGRA/ARGB/ABGR.
Updated in .process before the corrupted/size-0 skip so cursor-only Mutter
buffers still track movement.
- CapturedFrame gains cursor: Option<CursorOverlay> (Arc rgba + serial) riding
the GPU (Dmabuf/Cuda) payloads; the CPU de-pad path composites inline.
GPU composite into each zero-copy backend's owned surface:
- Vulkan Video + PyroWave: folded into the shared rgb2yuv.comp CSC shader —
cursor sampled and alpha-mixed over RGB before the YUV convert (correct
chroma, no extra pass). binding 3 (combined image sampler) + 16B push
constant, per-slot cursor image uploaded only on serial change. spv regenerated.
- CUDA/NVENC: real on-GPU kernel (cursor_blend.cu -> cursor_blend.ptx,
compute_75 Turing baseline, JIT-forward) with blend_argb/blend_yuv444/
blend_nv12 (BT.709 limited, matching the shader). Loaded via the hand-rolled
libcuda fn-table; blended into the ring InputSurface after copy, degrading to
no-cursor on any failure — never drops a frame.
VAAPI (AMD/Intel fallback) deferred: Vulkan Video already covers those GPUs;
blind libva struct-layout FFI shouldn't ship unverified.

A lid-closed laptop defeats both activation stages for a fresh IddCx
target: the clamshell lid policy suppresses the new-monitor
auto-activate, and the SDC_TOPOLOGY_EXTEND preset returns success
without committing a path for the IDD — so every session retry burned
~10s in resolve_target_gdi and the stream died with "not yet an active
display path" after 8 attempts (RDP/Parsec still work there: neither
needs a NEW console display path). Field report: Windows laptop host,
Intel iGPU, lid closed, v0.10.1.
New activate_target_path() (win_display.rs) is the supplied-config
apply Windows' own display Settings uses to turn a monitor on, which
doesn't consult the lid policy: QueryDisplayConfig(QDC_ALL_PATHS), keep
every active path verbatim, append the target's inactive path with a
source no active display is using (never a clone), both mode idxs
DISPLAYCONFIG_PATH_MODE_IDX_INVALID, then SDC_APPLY |
SDC_USE_SUPPLIED_DISPLAY_CONFIG | SDC_ALLOW_CHANGES |
SDC_SAVE_TO_DATABASE — SAVE_TO_DATABASE so the next same-identity ADD
auto-activates from the persistence DB and skips the ladder. Wired as
the THIRD stage of resolve_target_gdi; the on-glass-validated
auto-activate → force-EXTEND order is unchanged.
Also sweep stale "SudoVDA" out of logs/errors and current-behavior doc
comments (the backend was removed; pf-vdisplay is the sole one): the
capture error now names pf-vdisplay, the HDR toggle logs
virtual-display, and the not-active warns list the exhausted fallbacks.
Genuinely historical SudoVDA notes stay.
cargo check + clippy green on the Windows box; on-glass lid-closed
repro still owed.

Tester-diagnosed: Steam's GetControllerInfo SETs a query (0x83 attributes
/ 0xAE string) and GETs the answer; the virtual SC2 answered EVERY get
with a serial blob, so the 0x83 probe came back mistyped and Steam never
adopted the pad ("it does nothing").
- triton_feature_reply(): the GET answer now echoes the LAST SET's
command — the same validated state machine the virtual Deck ships —
framed on feature report id 1 (SDL's send framing for this device):
0x83 → the Deck-shaped 9-attribute blob with the Triton's product id
(0x1302) + per-instance unit id; 0xAE → the FVPF serial with the
requested string-attribute tag; anything else reads back as an echo.
Values beyond the product id mirror the Deck's hidraw capture (same
firmware family) — swap in a physical-pad capture if Steam still balks.
- Both legs track last_set and reply through the shared helper (the
usbip EP0 handler and the UHID GET_REPORT path); the serial/unit-id
helpers moved to triton_proto so the identities agree.
- Each distinct GET command is info-logged once ("answering feature
GET cmd=0x83") so the tester's journal shows the dance.
Committed without the usual .21 verify round (user request — verify
before push); --no-verify per the shared-tree fmt-hook false positive.

Flip the `pyrowave` cargo feature into the default set across punktfunk-host,
pf-client-core, pf-presenter and the session client — every packaged build
(flatpak, arch/rpm/copr, windows x64 client) now carries the codec. Selection
stays strictly per-session opt-in: a client must pick "PyroWave (wired LAN)"
in Settings (or PUNKTFUNK_PREFER_PYROWAVE=1); nothing changes for normal
HEVC/AV1 sessions. The Windows ARM64 client leg builds --no-default-features
and keeps skipping it (decode is Linux-native + Apple Metal today).
Advertisement no longer waits for the PUNKTFUNK_ENCODER=pyrowave lab
override on NVIDIA: host_wire_caps sets the bit whenever the feature is
present and the host isn't the GPU-less software pref, and
SessionPlan::output_format flips a PyroWave session on the NVIDIA-auto
capture path to CPU RGB frames (the EGL→CUDA import only NVENC consumes;
the wavelet backend ingests raw dmabufs or CPU RGB). AMD/Intel keep their
raw-dmabuf zero-copy unchanged; per-session raw-dmabuf passthrough on
NVIDIA (true zero-copy without the env's global capture policy) stays a
follow-up.
On-glass on .21 (RTX 5070 Ti, default-features binaries, NO env overrides):
host advertises + negotiates PyroWave, the CPU-capture fallback engages,
60 fps at e2e 3.2-5.7 ms p50, and a mid-stream 1080p→720p resize rides on
top cleanly. Workspace clippy --locked clean; 33 client + 314 host tests.

First on-glass run (wired pad + Puck, NixOS host "miko") surfaced three
things; all addressed:
Android (the create→unplug flap at 255 ms, and the Puck showing nothing):
- Read interrupt endpoints with UsbRequest/requestWait, not bulkTransfer —
Android only supports bulk transactions on bulk endpoints, so reads
returned the first buffered report and then -1 forever (tester-diagnosed).
One IN request stays queued; OUT reports (Steam's forwarded haptics) are
queued onto the reader thread, which is the single requestWait owner.
Unplug detection is now sustained-silence (5 s), not a failure counter.
- Wireless-status (0x46/0x79) is authoritative only through a Puck dongle:
a WIRED pad truthfully reports "no radio link" and must not tear the
slot down (this alone explained the wired flap's remove event).
- Lizard-off confirmed working on-glass — framing unchanged.
Host (Steam confirmed to ignore the UHID leg, Interface: -1 — the Deck
story repeating):
- triton_usbip.rs: the virtual SC2 now attaches via vhci_hcd as a REAL USB
device, byte-matched to the tester's lsusb capture of the wired pad
(28DE:1302, bcdDevice 3.07, class EF/02/01, Full Speed, one HID
interface #0 with interrupt IN 0x81 / OUT 0x01, 64 B, bInterval 1,
bcdHID 1.11, Valve strings; FVPF-prefixed serial so the 28DE conflict
gate recognizes it as ours). Interrupt-IN mirrors the client's raw
reports; interrupt-OUT captures Steam's haptic output reports (0x80
parsed for the 0xCA plane, everything forwarded raw); EP0 SET_REPORT
features normalize to id-first framing and forward raw.
- steam_usbip.rs: the attach choreography (in-process sysfs attach → usbip
CLI fallback) extracted into a shared UsbipAttachment used by the Deck
and the SC2 device models — behavior-identical for the Deck.
- steam_controller2.rs: transport ladder usbip → UHID (the fallback now
warns that Steam won't list it, with the modprobe vhci_hcd remedy).
Verified: host 314 tests green on Linux (.21) incl. the new device-model
units; on-box smoke attaches the virtual 28DE:1302 through vhci_hcd (real
USB enumeration, not /devices/virtual) and tears down on drop. Owed: the
tester's Steam-visibility check against the usbip leg + Android retest.
(--no-verify: the fmt pre-commit/pre-push checks trip on ANOTHER session's
uncommitted WIP in the shared tree; every file in this commit is
rustfmt-clean and the committed tree passes cargo fmt --check.)

The Apple client now decodes PyroWave natively on the presenter's own MTLDevice —
no MoltenVK, no upstream C++ in the app. Completes and wires up the decoder whose
early working-tree snapshot rode along in 9127c346:
- MetalWaveletShaders.swift: wavelet_dequant + idwt hand-ported from the vendored
GLSL (STORAGE_MODE 0 only; subgroup scans → 32-wide simdgroups; DCShift spec
constant → function constant; precision-1 split: fp16 levels 0-1 / fp32 2-4).
- MetalWaveletDecoder.swift: Swift reimplementation of push_packet/decode_packet
incl. the Phase-4 chunk-aligned window walk (FRAG chains, zeroed missing shards,
the >half-blocks partial rule), init_block_meta's block-index space, and the
42-dequant + 13-idwt dispatch structure with encoder-boundary barriers. SOF-dims
changes rebuild the size-dependent resources, which is also the mid-stream
resize path. Ring of 4 output plane sets on the presenter's queue.
- Presenter: pf_frag_planar (3xR8, the planar_csc.frag twin) + renderPlanar with
a shared present tail; ReadyFrame carries an image enum (.video | .planar).
- Stage2Pipeline: a dedicated PyroWave pump — no VideoToolbox machinery, no
keyframe/re-anchor recovery (all-intra; partials render as localized blur by
design), newest-frame-index staleness guard for late partials.
- Opt-in: "PyroWave (wired LAN)" codec entry (probe-gated, ≈A13 floor via a real
kernel-compile probe), selecting it advertises + prefers the codec and forces
the session SDR (HDR/10-bit/4:4:4 caps dropped, plan contract).
- Core ABI: punktfunk_connection_shard_payload() — the Welcome's negotiated shard
payload, needed by native decoders to walk chunk-aligned AUs.
- Validation: golden fixtures generated by the host encoder + upstream's own
decoder (pyrowave_dump_golden, RTX 5070 Ti); the Metal decode PSNR-matches at
77-88 dB across all planes for dense AND chunk-aligned AUs, and a hole-punched
partial still decodes. Parser unit tests cover the window walk, FRAG chains,
broken chains, the half-blocks gate, and the block-index layout.
Tests: apple 134 green (mac; iOS/tvOS build), host 312 w/ pyrowave on .21,
core 148 w/ quic; clippy/fmt clean.

- pf-presenter: the HUD/title mode line lived inside the match-window (D2)
gate, so an accepted switch from any OTHER trigger (the
PUNKTFUNK_DEBUG_RECONFIGURE lever, a host-side corrective rollback) left the
label stale. Hoisted into its own per-iteration tick that runs whenever a
stream is up.
- docs: pyrowave.md — the Automatic bitrate pin now follows a mid-stream
resize; drop the "resolution changes rebuild the stream" limitation.
Completes the resize-rebuild work whose core landed in 9127c346
(video_pyrowave.rs sequence-header dims sniff + in-place decoder/plane-ring
rebuild with retired-ring lifetime handling, host per-mode ~1.6 bpp re-pin,
128px floor, debug reconfigure lever). On-glass validated on .21
(RTX 5070 Ti, Mutter virtual display): 1080p->720p and 1080p->1440p
mid-stream switches, lossless AND under 2% netem loss — decoder rebuilt in
place, 60 fps sustained (partials during loss), pinned rate re-resolved
199065->88473 / ->353894 kbps, HUD flips to the new mode.

- clients/apple: native Metal wavelet decoder + compute shaders (Phase 5),
decoding PyroWave without embedding MoltenVK.
- pf-client-core: plumb user_flags/completeness through Decoder::decode_frame
so the PyroWave backend parses chunk-aligned + partial AUs; gate the param's
unused-warning to exactly the non-pyrowave builds (fixes -D warnings on the
featureless Linux client build).
- punktfunk-host: on a mid-stream mode switch, re-resolve the "Automatic"
PyroWave bitrate for the new mode's ~1.6 bpp operating point (explicit rates
and H.26x ABR stay put); reject sub-128px PyroWave modes before the encoder
rebuild instead of after the ack.

The 2026 Steam Controller (Valve "Ibex" / SDL "Triton") captured on an
Android client is passed through AS-IS: the host presents a virtual pad
with the real wired identity (28DE:1302) and mirrors the physical pad's
raw HID reports, so Steam on the host drives it over hidraw exactly like
the real thing — trackpads, gyro, paddles, and its rumble/settings writes
flow back onto the physical controller. Protocol ground truth: SDL's
Valve-maintained SDL_hidapi_steam_triton.c + steam/controller_structs.h.
Core:
- GamepadPref::SteamController2 (wire byte 9; names steamcontroller2/
sc2/ibex) + PUNKTFUNK_GAMEPAD_STEAMCONTROLLER2 in the C ABI.
- Raw HID planes: RichInput::HidReport (0xCC/0x04, client→host input
reports verbatim, Copy fixed-64 body) and HidOutput::HidRaw (0xCD/0x05,
host→client feature/output writes for replay). Best-effort is sound by
the device protocol's own design (rumble re-sent every ~40 ms, settings
every ~3 s — losses self-heal); HidRaw bypasses hidout dedup for
exactly that reason.
Host (Linux):
- triton_proto.rs + steam_controller2.rs: Triton2Manager UHID backend —
no kernel driver binds the PID (hidraw only; Steam Input is the
consumer), raw mirroring with a typed-fallback 0x42 synthesizer until
the first raw report, SET_REPORT ack + raw forward, canned GET_REPORT
serial reply, rumble also parsed onto the universal 0xCA plane (phone
mirror). Rides the uhid + 28DE-conflict degrades; UHID promotion by
Steam is flagged in the creation log (usbip transport is the known
follow-up if Steam ignores Interface:-1 devices for Triton too).
Android:
- Sc2UsbLink (wired/Puck: vendor-interface claim detaches the OS driver,
interrupt read loop, lizard-off on the watchdog cadence, raw replay via
interrupt-OUT / SET_REPORT with hidapi report-id framing) and Sc2BleLink
(Valve vendor GATT service, notify subscribe machine, 0x45 re-framing,
HIGH connection priority).
- Sc2Capture orchestrator: raw plane + typed mirror (exit chord + host
degrade paths keep working) on a GamepadRouter external slot; raw
return path via GamepadFeedback.onHidRaw.
- nativeSendPadHidReport JNI (direct ByteBuffer, no per-report copy),
hidout raw decode, usb-host/BLUETOOTH_CONNECT manifest bits, opt-out
settings toggle, StreamScreen engagement incl. the USB permission flow.
Verified: core 149 + host 312 tests green on Linux (.21), on-box uhid
smoke creates/mirrors/tears down the virtual 28DE:1302, C ABI harness
round-trips, Android compileDebugKotlin green. On-glass with the real
controller owed.

PyroWave AUs now packetize on the negotiated shard payload, so a lost datagram
costs a few wavelet blocks of localized blur rather than a whole frame — and the
client can render an aged-out lossy frame instead of freezing until the next one.
Host (opt-in, PyroWave only):
- The encoder packetizes at the shard payload behind a 4-byte window prefix
(used-len u16 + kind u16). Whole packets pack into WIN_PACKED windows; a packet
too large for one shard (PyroWave 32x32 blocks are atomic and can exceed a
shard) rides a WIN_FRAG_FIRST/CONT/LAST chain. `set_wire_chunking()` joins the
Encoder trait (forwarded through TrackedEncoder — the silent-no-op trap);
EncodedFrame.chunk_aligned marks the AU.
- virtual_stream tags the AU with USER_FLAG_CHUNK_ALIGNED and re-applies chunking
after every encoder (re)build, the adaptive-bitrate rebuild included.
Core:
- USER_FLAG_CHUNK_ALIGNED (0x40) wire bit. Reassembler opt-in
(set_deliver_partial): a chunk-aligned frame that ages out with holes is handed
over as Frame{complete:false} — received shards at their exact offsets, missing
ranges zero-filled — instead of being dropped. Partials age out on a tight 30ms
fuse (PARTIAL_WINDOW_NS) instead of the 120ms loss window: each frame is
independently decodable, so an ancient partial has no value in a live stream.
Newest-wins. A partial still counts as dropped for loss reporting.
Client (PyroWave decode):
- The session opts in when codec == PyroWave. The decoder walks the AU
window-by-window, skipping zero (missing) windows and reassembling FRAG chains,
then decodes whatever survived. A newest-decoded-index guard drops partials the
pump has already moved past (no time-travel present).
Also fixes a redundant-closure clippy nit in the PyroWave planar-present path.
Validated on an RTX 5070 Ti under 2% netem loss with FEC pinned off: 60fps
sustained entirely via partials, e2e 43ms p50 (146ms before the fuse) vs 23ms
lossless, no keyframe-recovery chatter. Tests green: core 149, host 310 + the
GPU-gated encoder smoke (framed-window walk + FRAG reassembly + upstream
round-trip), client 26; clippy clean on the pyrowave feature combos.

A host's pairing-gate rejections (not armed / bound to another device /
rate-limited / identity required / denied / approval timeout / superseded /
wire-version mismatch) used to drop the connection with a bare code-0 close,
and every client collapsed that — plus plain unreachability — into one
"wrong PIN / not accepted" message. A dead network path, a disarmed host,
and an operator denial were indistinguishable, which is exactly the
misdiagnosis behind the recent Android pairing support thread.
- core: new ungated `reject` module — shared close-code block 0x60–0x67
(+ 0x42 busy promoted from the host), `RejectReason`, and
`PunktfunkError::Rejected`; `pair()`/`connect()` decode the host's
ApplicationClosed code into `Rejected` instead of a generic Io error.
C ABI v7: status block −20…−28 and `punktfunk_connect_ex8` (`status_out`
reports the failure cause; NULL-return alone can't). Wire unchanged —
old peers see exactly the old bare close.
- host: every gate rejection `conn.close()`s with its typed code (and the
human reason as close bytes) before erroring out of the session task.
- pf-client-core: shared `pair_error_message`/`connect_reject_message`
wording consumed by the Windows + Linux + console-UI + CLI surfaces; a
connect failure now renders the host's stated reason.
- android: `nativeTakeLastError()` JNI token + `ConnectErrors.kt` — a
network timeout is no longer reported as "wrong PIN, or the host isn't
armed", and a typed rejection skips the wake-and-wait fallback (the host
is demonstrably awake).
- apple: `HostRejection` + `.rejected`; the pair sheet and session alerts
show the stated reason; connect moves to `ex8`.
Completes the cross-client half of the hunks that rode along in 12148243
(client.rs / trust.rs / punktfunk1.rs) — main did not build without this.
Validated: workspace clippy -D warnings + full test suite green on .21
(EXIT=0, 309 host / 148 core suites); macOS core 147+c_abi green; swift
build green; Android Kotlin + native crate green.

plan §4.6 + Phase 3 productization:
- Pinned bitrate: an Automatic client (bitrate 0) on a PyroWave session
resolves to the codec's ~1.6 bpp operating point for the mode (≈200
Mbps at 1080p60) instead of the 20 Mbps H.26x default; explicit rates
are honored. Mid-stream SetBitrate retargets are refused with the
pinned rate acked (guards old/foreign clients), and the client-side
AIMD controller + startup capacity probe stay off for the codec — no
rate descent into wavelet mush, no climb probe whose VBV reasoning
doesn't apply to hard per-frame CBR. Unit-tested.
- All-intra silencing: the data plane drops drained keyframe/RFI
requests on PyroWave sessions (the next frame IS the recovery), so
the forced-IDR cooldown, RFI attempt, and storm coalescing never run.
- Opt-in UI: 'PyroWave (wired LAN)' joins the console's Video-codec
cycler; trust::Settings maps it to CODEC_PYROWAVE. Safe everywhere by
the negotiation contract — an un-advertised preference falls back
through the ladder.
- FEC: decision recorded — adaptive FEC (10% start, loss-report driven)
stays as-is for the MVP opaque-AU mode; the FEC≈0 policy belongs to
the Phase-4 datagram-aligned mode.
- THIRD-PARTY-NOTICES: the generator now lists third-party trees
vendored inside first-party crates (pyrowave, Granite subset, volk,
Vulkan-Headers) with their full license texts; file regenerated.
- docs-site: 'PyroWave (wired-LAN codec)' page — what it is, the
bandwidth table, how to enable it, current limits.
Validated on .21: 309 host + 148 core + 26 client tests green,
console-ui clean, both feature configs.

The pyrowave passthrough rode VAAPI's LINEAR-only modifier policy, which
starves it on Mutter+NVIDIA (tiled-only allocations → the compositor
declines the offer → CPU capture fallback). The encoder imports through
VK_EXT_image_drm_format_modifier, not libva, so the capture now extends
the advertisement with every single-memory-plane modifier the PyroWave
device samples from (probed via DrmFormatModifierPropertiesListEXT with
the same device selection as the encoder).
Live on .21 (Mutter+NVIDIA, RTX 5070 Ti): 7 modifiers advertised, the
compositor negotiated block-linear (216172782120099861), no CPU
downgrade, and the encoder's per-buffer import cache populated exactly
as designed (8 PipeWire pool buffers imported once, silent reuse after).
Zero-copy session numbers: static 60 fps, e2e 2.9-3.0 ms p50 (p95 3.4),
host stage 1.6 ms; full-window motion 60 fps at ~80 Mb/s all-intra,
decode ~1 ms. Also neutralizes the VAAPI-specific wording in the
passthrough hand-off log.

Found by the first live session on .21: the host negotiated PyroWave
and put codec=8 on the wire, but Welcome::decode's codec whitelist
(H264/AV1, else HEVC — the corrupt-byte guard) folded it to HEVC, so
the client opened an FFmpeg HEVC decoder against wavelet AUs. Roundtrip
test now pins the pyrowave byte (and that a genuinely unknown future
bit still folds to the HEVC default).
With the fix the Phase-2 exit session runs END TO END on .21
(host + session client on one box, host capturing the GNOME virtual
display, client presenting into a headless weston):
negotiated codec=PyroWave (adv 0x0f) → PyroWave encoder (CPU-capture
path — this box's Mutter+NVIDIA rejects the LINEAR-dmabuf offer) →
wire → PyroWave decoder on the presenter's device → planar CSC.
Static desktop: stable 60 fps, e2e 2.1-4.1 ms p50 (p95 <= 6 ms),
decode 0.2-0.6 ms, vs HEVC/NVENC-direct baseline 2.1 ms — parity at
idle. Full-window motion: 60 fps at ~80 Mb/s all-intra (HEVC ~7),
decode still sub-ms, zero decode errors or keyframe-request chatter
across every run. Deeper motion/loss characterization needs a
dmabuf-accepting host box (this one is capped by the CPU capture
path).
Also retires the stale "no shipping client decodes this" wording in
the host encoder/dispatch logs — the negotiation exists now.

ci.yml's -D warnings clippy (default features) flagged the labeled block
whose only break lives behind the pyrowave cfg — restructured as cfg'd
let-bindings, no label. Also boxed Backend::PyroWave (the decoder's

clippy::large_enum_variant under the feature).
Both configs strict-clippy clean on .21; 26 tests green.

The pump now advertises decodable_codecs_for(presenter device) — the
CODEC_PYROWAVE bit rides only when the device passed the compute-feature
probe — and PUNKTFUNK_PREFER_PYROWAVE=1 is the Phase-2 lab opt-in that
names the codec in preferred_codec (the only route resolve_codec will
take it, plan §3; a Settings toggle is Phase-3 productization). A
negotiated PyroWave session builds Decoder::new_pyrowave on the
presenter's device instead of an FFmpeg decoder. clients/session grows
the `pyrowave` feature forwarding both crate features.
With this the Phase-2 client chain is code-complete:
Hello bit → preference → Welcome::codec → pyrowave decode on the
presenter device → planar CSC → present. On-glass .21 run +
latency-probe/loss-harness numbers vs HEVC remain owed (plan Phase-2
exit criteria).
Validated on .21: session client + all crates compile with and without
the features, clippy clean, 26 + 308 tests green.

The arch package job (--features nvenc) tripped the same class of
Codec::PyroWave non-exhaustive matches as windows-host had, in
nvenc_cuda.rs (6 sites) — dispatch-guarded unreachable!() arms, plus
the vk_util-extraction leftover unused imports in vulkan_video.rs.
All Linux host feature combos (none / pyrowave / nvenc,vulkan-encode /
all three) now compile clean on .21.
Presenter: planar_csc.frag (+ committed .spv) — the 3-plane variant of
nv12_csc.frag (separate Cb/Cr R8 planes, same push-constant CSC-row
contract, siting correction self-disables at full-res chroma).
CscPass grows a shared builder + new_planar()/bind_planes_planar()
(GENERAL-layout descriptors — pyrowave planes stay GENERAL); the Vk
presenter builds the planar pass when the device passed the pyrowave
probe, FrameInput::PyroWave rides present_frame (no acquire barrier
needed: the decoder fence-completed and barriered the planes on the
same queue), and run.rs presents it with no demote rung (only device
loss ends the session).

The presenter's device creation now probes + enables the PyroWave
compute feature set alongside the Vulkan Video probe (shaderInt16,
storageBuffer8BitAccess, subgroup size control — gated on support,
harmless when unused) and exports the facts through VulkanDecodeDevice
(pyrowave_decode capability + feature bools + apiVersion + the queue-
family shape).
pf-client-core (feature `pyrowave`, Linux): video_pyrowave.rs — the
decoder runs pyrowave compute on the PRESENTER's own VkDevice, zero
interop (plan §4.5): pinned content-equivalent create-info
reconstruction satisfies pyrowave 0.4.0's lifetime rule without
refactoring the presenter's creation; queue access rides the existing
device-wide QueueLock (the FFmpeg/Skia contract); decode records into
our command buffer, fence-synchronous (sub-ms), into a 4-deep ring of
3xR8 plane sets (decode REQUIRES storage usage + identity swizzles, so
the encoder's RG8 trick doesn't apply). Backend::PyroWave +
DecodedImage::PyroWave + Decoder::new_pyrowave + decodable_codecs_for
(advertisement gated on the device probe) wired through the decode
dispatch; no demote ladder (nothing else decodes it — fallback is
session renegotiation, plan §4.6).
Still to come for a live session: the presenter's planar-CSC render
path for the new variant, pump/shell opt-in (preferred_codec) wiring,
and the on-glass .21 run.
Validated on .21: pf-client-core + pf-presenter compile with and
without the feature, clippy clean, 26 client-core tests green.

The nine non-exhaustive matches windows-host CI tripped on (run 9917) —
all inside encoder objects a PyroWave session can never open (the
open_video dispatch routes PyroWave to its own backend on Linux and
bails on Windows), so the arms are dispatch-guarded unreachable!().
Verified: cargo check -p punktfunk-host --features nvenc,amf-qsv
--release green on the windows-amd64 runner.
