enricobuehler	ecfa71212d	chore: consolidate all in-progress parallel-session WIP ... Wholesale commit of every uncommitted change across the tree, at the user's explicit request — host refactor-campaign W1 (native.rs facade + native/ dir, library/ + mgmt/ splits), Android, core. These streams were mid-flight and not individually built/tested together; this supersedes the per-session HOLD markers. Consolidating so everything lands on main in one pass.

enricobuehler	571e22bc0f	refactor(core): consolidate the fingerprint-pinning verifier into core::tls ... 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.

enricobuehler	1f519d44f9	docs(core): backfill //! module docs on quic/{io,endpoint,pake} ... The last three //!-less modules in the tree (plan §2.5 / §3.2): - io: length-prefixed control-message framing (read_msg/write_msg) - endpoint: QUIC endpoint construction + transport tuning + the TOFU cert-pinning verifier (PinVerify) - pake: SPAKE2 pairing key exchange Docs only — no code, type, or wire-format change (cbindgen header byte-identical).

enricobuehler	11045a0f70	chore: consolidate parallel-session WIP (HOLD — do not push) ... 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.

enricobuehler	01266ff18d	feat(gamepad): SC2 Puck-dongle passthrough with the native 28DE:1304 topology ... 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 Verified: clippy -D warnings + 319 host tests green on Linux, core wire tests green, Android kit/app compile + unit tests green. On-glass Puck retest owed. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-15 20:47:52 +02:00
enricobuehler	ff38933312	feat(core,apple,session): report decode latency from the Apple + Windows/Linux clients too ... 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.

enricobuehler	56f9c8c4b4	feat(core,android): Automatic bitrate caps at the client decode limit, not the link ceiling ... 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. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>	2026-07-15 17:28:11 +02:00
enricobuehler	739a5f76bf	feat(apple): PyroWave Phase 5 — native Metal decode on Mac / Apple TV / iPad (§4.7) ... 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. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-15 12:16:43 +02:00
enricobuehler	2621b6e6b1	feat(core,host,android): Steam Controller 2 as-is passthrough to Linux hosts ... 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. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-15 11:22:16 +02:00
enricobuehler	705a8baddf	feat(core,host,client): PyroWave datagram-aligned packets + partial-frame delivery (Phase 4, §4.4) ... 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.

enricobuehler	1fc9ef0050	feat(core,host,clients): typed pairing rejections — every client says WHY, not "not accepted" ... 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.

enricobuehler	12148243bd	feat: PyroWave Phase 3 — pinned rate, all-intra silencing, opt-in UI, notices, docs ... 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. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-15 09:45:49 +02:00
enricobuehler	719b1ef403	fix(core): let CODEC_PYROWAVE survive the Welcome decode whitelist ... 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.

enricobuehler	e71cb9b7bd	feat(core,host): CODEC_PYROWAVE negotiation — opt-in only, host dispatch wired ... Phase 2a+2c of design/pyrowave-codec-plan.md. Core: CODEC_PYROWAVE = 0x08 on Hello::video_codecs/Welcome::codec. Deliberately absent from resolve_codec's precedence ladder (plan §3 — a 100-400 Mbps codec must never win a negotiation by mere mutual support): reachable exclusively through the client's explicit preferred_codec. Invariant tests cover never-auto-selected (even as the only shared codec), preferred-path selection, and graceful fallback. ABI mirror PUNKTFUNK_CODEC_PYROWAVE + lockstep assert for the Apple/Android embedders. Host: Codec::PyroWave variant threaded through the wire mappings; a negotiated PyroWave session routes straight to the backend ahead of the PUNKTFUNK_ENCODER pref dispatch (which stays a lab override). The advertisement bit rides host_wire_caps only when the capture side would actually deliver ingestible frames — linux_zero_copy_is_vaapi(), i.e. AMD/Intel auto or an explicit operator pref on NVIDIA; per-session raw-dmabuf OutputFormat plumbing is recorded as the Phase-3 item. The libavcodec name helpers are dispatch-guarded unreachable; the web console gains ApiCodec::PyroWave (api/openapi.json regenerated). Validated on .21: 308 host tests green with and without the feature, 145 core tests green with quic, clippy clean. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-15 01:14:04 +02:00
enricobuehler	9d67dc18aa	perf(core): two-lane AES-GCM seal for large frames + send-thread stage split ... Phase 0.4 host half: PUNKTFUNK_PERF now splits the send thread per window into fec/seal/sock (SealPerf via Session::take_seal_perf; the paced video path folds its chunk-send time in through note_sock_ns), logged with per-packet ns in the send loop's perf line. Measured on .21 at 2.5 Gbps offered: fec ~100 ns/pkt (Phase 1.4 landed), seal ~1000 ns/pkt = 21.5% of a core, sock ~1400 ns/pkt — the Phase 1.5 gate (seal > ~15% of the thread at 2 Gbps) trips. Phase 1.5: seal_frame_inner is now write-then-seal — packetize writes every packet's plaintext at its final wire offset, then a frame of >= 256 wire packets (~300 KB) splits the AES-GCM pass across two lanes: a persistent punktfunk-seal2 worker (lazy-spawned, rendezvous channels, no per-frame spawn, zero steady-state allocs via a reused hand-off Vec) seals the back half under nonces seq_base+i while the send thread seals the front. Nonce order is deterministic per shard index, so the wire is byte-identical to the sequential pass — pinned by the wire-equivalence test, now including a 469-packet frame plus an assertion that the lane actually spawned. Small frames and the probe's ~17-packet AUs stay single-lane; PUNKTFUNK_SEAL_LANES=1 forces single-lane. Validated: 84 core tests + workspace suites + clippy -D warnings on .21. Halves the seal wall-clock on big frames — headroom for the 10G pair's ~4.8 Gbps ceiling (seal alone would be ~47% of a core there) and PyroWave 4K rates.

enricobuehler	f4f6c5556f	perf(core): FEC encoder reuse — cached codecs + pooled parity, no per-block setup ... Phase 1.4 (throughput-beyond-1gbps.md): the send path built a fresh erasure codec and allocated fresh parity Vecs for every FEC block. New trait method ErasureCoder::encode_into generates parity into caller-pooled buffers; the packetizer keeps one parity pool that grows once to the session's high-water recovery count. - gf16: one cached reed_solomon_simd::ReedSolomonEncoder per coder, re-shaped per block via reset() (reuses its working space) — the old encode() convenience call paid engine CPU-feature detection, FFT planning, and work-buffer allocation per block. - gf8: last-used (k, m) Cauchy codec cached, so the generator-matrix build drops out of steady-state frames; parity buffers shaped without re-zeroing (encode_sep's first-input pass overwrites every row). The GameStream VideoPacketizer now owns a persistent coder so the cache survives frames. - encode() delegates to encode_into — one code path, and the nanors byte-exact parity vector keeps pinning Moonlight wire compatibility. Validated: 145 core + 308 host tests + clippy -D warnings on .21, loss-harness recovery curve identical, pipeline bench +0.6-2.4% thrpt (all configs, p<0.05; the loopback bench is encoder-dominated so the alloc savings mostly land outside it).

enricobuehler	5a384fe788	feat(host): pace-aware send chunking — high-rate frames pace honestly instead of blasting ... Phase 1.2: the native plane's pace chunks are rate-adaptive — 16 packets at today's rates, coarsening until the per-chunk interval clears the 500 µs sleep floor, capped at 64 (the GSO segment limit). Decouples the syscall batch from the pace step, so a ≥1 Gbps frame's overflow keeps real sleeps between chunks (and costs 4× fewer syscalls) instead of collapsing into an unpaced blast. Phase 1.3: the auto microburst cap scales with the frame — max(128 KB, the AU's wire bytes / 4) — so high-rate frames burst a bounded quarter and pace the rest; PUNKTFUNK_PACE_BURST_KB now pins an absolute override. GameStream plane untouched (its schedule stays pinned by the deterministic tests, now also asserting budget-independence). Linux GSO latch-off warns once (was silent; USO already warned). Linux GSO default stays OPT-IN: the post-1.2/1.3 A/B on the 2.5GbE-hop pair (.21 → M3 Ultra) reproduced the regression bit-for-bit — 2452 Mbps sendmmsg vs 1909 GSO peak, 0.4% loss at 1500 where sendmmsg is clean. The super-buffer trains lose on the constrained hop in the transport path itself (per-AU probe sends, no video pacer involved), so the block is fabric evidence, not pacing readiness. Control sweep on this build matched the sendmmsg baseline exactly (2452); loss-harness recovery curve identical; workspace clippy + tests green on .21.

enricobuehler	a2433d77cf	fix(core): reordering no longer reads as packet loss — net late shards out of the loss estimate ... Reversed/reordered delivery lets a FEC block reconstruct EARLY (data + recovery >= k), counting still-in-flight shards into fec_recovered_shards; window_loss_ppm then reported pure reordering as loss, inflating LossReports — which size adaptive FEC and, since the Automatic overhaul, feed the ABR controller (one severe window ends slow start FOR GOOD, so a reorder burst could permanently kneecap a session's climb). Early reconstruct stays (it's the latency-right choice); the accounting now nets it out. The reassembler counts a new fec_late_shards stat when a parity-restored data shard ARRIVES after all — matched exactly: the completed/abandoned-frame memory (ReassemblyWindow::completed, now a map) remembers which shards each terminal frame reconstructed, and a late arrival must match one (removed on hit), so wire duplicates of delivered shards and stragglers of failed blocks count nothing. In-flight blocks dedup via have_data. window_loss_ppm takes the late delta and estimates from (recovered - late), saturating across window boundaries; both callers (client core + probe) pass it. The e2e reorder tests now assert the NET equals the true kill count in both delivery orders, dup included (previously documented as a known inflation). Not mirrored into the C-ABI PunktfunkStats — the loss windows run in-core on every platform. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-14 20:59:17 +02:00
enricobuehler	9bf72cdfb5	fix(host): forward reconfigure_bitrate through TrackedEncoder + probe --rebitrate validator ... The gpu-session TrackedEncoder wrapper delegates every Encoder method by hand, so the new reconfigure_bitrate fell through to the trait's false default and EVERY bitrate change silently took the rebuild+IDR path — the live .21 A/B caught it (host log said 'rebuilt', never 'in place'). Also: - punktfunk-probe --rebitrate KBPS:SECS — headless mid-stream SetBitrate validator (cursor-wiggles so a damage-driven idle desktop keeps publishing frames through the switch). Live-verified on .21: one NVENC session open, then 'encoder bitrate reconfigured in place (adaptive bitrate — no IDR)' at 20→60 Mbps. - on-hardware nvenc_cuda reconfigure smoke test (20→60→10 Mbps in place, zero IDRs — green on the RTX 5070 Ti). - BitrateChanged doc no longer claims the switch costs an IDR.

enricobuehler	9b7fc127ef	feat(core): Automatic bitrate scales to measured link capacity — probe ceiling + slow start ... The ABR ceiling was the negotiated start rate, so an 'Automatic' session was permanently boxed at the 20 Mbps default no matter the link — the most user-visible cap left after the transport work lifted the client receive ceiling to ~4.8 Gbps wire. - Startup link-capacity probe: ~2 s into an Automatic session the pump fires one speed-test burst (2 Gbps target, 800 ms) over the existing ProbeRequest machinery; delivered wire throughput x0.7 (FEC + variance headroom) becomes the controller's climb ceiling via set_ceiling(). Old hosts decline (all-zero reply) or never answer (a 6 s timeout clears the stuck probe state so LossReports resume) — the ceiling then stays negotiated, exactly the old behavior. PUNKTFUNK_ABR_PROBE=0 opts out. - Slow start: until the first congestion signal, every cooled clean window DOUBLES the rate toward the ceiling (20 Mbps -> 640 Mbps in ~10 s) instead of +6% per ~10 s (which would have taken ~10 minutes). Any congestion signal ends it for good; classic AIMD takes over. - Faster, severity-aware AIMD: a SEVERE window (unrecoverable frame, jump-to-live flush, or >=6% loss) backs off x0.7 immediately instead of waiting two windows; ordinary congestion (2-6% loss, OWD rise) keeps the two-window fuse. Additive climbs need 6 clean windows (~4.5 s, was ~10 s); the change cooldown drops 3 s -> 1.5 s. - PUNKTFUNK_VBV_FRAMES now also scales the direct-NVENC VBV (Windows + Linux, previously hardwired to 1 frame) — parity with AMF/VAAPI/QSV. Each accepted step still costs an encoder rebuild + IDR on the host; in-place rate reconfigure (NvEncReconfigureEncoder / AMF dynamic properties / Vulkan per-frame RC) is the planned follow-up that makes stepping free. Controller tests rewritten to the new policy (severity classes, slow-start climb, ceiling semantics; 144 green). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-14 19:28:11 +02:00
enricobuehler	1a559e8d5e	feat(core): scale the receive path to the new multi-Gbps ceiling ... - REPLAY_WINDOW 32768 -> 131072: the anti-replay bitmap covered the 120 ms loss window only to ~2 Gbps; the client now delivers ~4.8 Gbps wire, where a late-but-valid Wi-Fi-retried datagram would have been dropped as 'older than the window' — false loss. 16 KiB/session covers ~12 Gbps. - RECV_BATCH 32 -> 128: syscall rate stays ~3.4k/s at 430k pkt/s and each pump iteration drains the kernel buffer deeper (ring 64->256 KB, client sessions only). flush_backlog's iteration cap rescaled to keep its ~190 MB guard equivalent. - PUNKTFUNK_GSO gate is now value-aware: '=0' used to ENABLE GSO on Linux (presence check) while disabling Windows USO. GSO stays OPT-IN, deliberately: A/B'd twice today — it cuts send-thread CPU ~30% but its 16-packet line-rate trains cost delivered throughput on a constrained fabric (2.5GbE-hop pair: peak 2453 -> 1908 Mbps and 0.4% loss at a rate sendmmsg carries clean). Flipping the default belongs with pace-aware chunk spacing (plan Phase 1.2/1.3). docs-site row corrected to match. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-14 19:22:40 +02:00
enricobuehler	ed0ce5dc6d	feat(core): zero-copy pooled reassembly — shards land at their final AU offset ... Rewrite the client Reassembler around one whole-frame buffer per frame: frame_bytes rides in every header and packetize geometry is deterministic (every non-final block is exactly max_data_per_block data shards), so a data shard's final AU offset is computable on arrival — copy it there once, straight from the decrypt ring. New ErasureCoder::reconstruct_into decodes ONLY the missing shards directly into the frame buffer's holes (gf16 native; gf8 legacy shim); received recovery shards ride pooled shard-sized buffers. The completed buffer IS Frame::data. Deletes the per-shard to_vec + per-block concat + final AU concat (~178k allocs and a double copy of every byte per second at 2 Gbps — the pump wall the 2026-07-14 sweeps measured at 98.9% of an M3 Ultra core). Reassembly now costs ~0.4 µs/packet in-stream. The eager buffer changes the hostile-header exposure, so two new firewalls: derived-geometry validation (a header lying about its data_shards/block_count vs its own frame_bytes is dropped before it can scribble across another shard's range) and an in-flight allocation budget (IN_FLIGHT_BUF_FACTOR × max_frame_bytes) so a window of tiny first-shards can't commit gigabytes. Behavior parity pinned by the existing suite (all green unchanged) plus new end-to-end roundtrips through the real Packetizer (multi-block + partial tail, loss within budget, reversed delivery, duplicates, empty frame, unrecoverable block ages out, budget enforcement). loss-harness recovery curve identical; pipeline bench: gf8/1MB +42%, gf16 neutral (host-encode dominated). Known pre-existing quirk kept as-is: reversed delivery reconstructs early (data+recovery ≥ k) and counts late-not-lost shards into fec_recovered_shards.

enricobuehler	0058f624a2	feat(core): receive-path stage timing + frame-jitter observability (PUNKTFUNK_PERF) ... Session::poll_frame accumulates per-stage ns (recv_batch syscall, AES-GCM open, Reassembler::push incl. FEC) into a PumpPerf drained via take_pump_perf(); the client pump logs the split plus completed-AU inter-arrival jitter (p50/p95/max + late count) every report window. Gated on PUNKTFUNK_PERF — one branch per stage when off. Smoothness previously had no metric at all (jump-to-live counters fire seconds late), and the receive core had no attribution. First live use pinned the 1.57 Gbps client wall on software AES-GCM (7 µs/pkt) vs 0.4 µs reassembly — see punktfunk-planning/design/throughput-beyond-1gbps.md.

enricobuehler	d8e8529cd7	feat(gamepad): Windows Steam Deck backend — Steam-Input-promoted UMDF virtual Deck ... The N4 GO verdict, productized. GamepadPref::SteamDeck on a Windows host now builds a real virtual Deck instead of folding to DualSense: games get native Deck glyphs + both trackpads + gyro + all four back grips through Steam Input's own remapping. - steam_deck_windows.rs: DeckWinPad/DeckWinProto/SteamDeckWindowsManager over the sealed shm channel, sharing the whole Linux Deck codec (steam_proto now compiles on Windows too — it was already pure). The SwDevice identity carries usb_mi: Some(2): the &MI_02 hardware-id token hidclass mirrors into the HID child and Steam parses as the wired controller interface — the promotion gate. - Driver: DEVTYPE_STEAMDECK (3) graduates from the spike — SET_FEATURE 0xEB rumble / 0x8F haptic pulses are republished to the host through the output slot (report-id-0 prefixed, so parse_steam_output sees the Linux wire shape), and the 0xAE/GET_STRING serial + 0x83 unit id are per-pad (read from the section's pad_index; PFDK<unit-id> matches steam_proto::deck_serial). - Router: SteamDeck arms in the Windows Pads paths; pick_gamepad flips SteamDeck-if-windows -> SteamDeck (the DualSense fold retires); dualsense-windows-test grows --deck. ON-GLASS VALIDATED on .173 (rebuilt signed driver 9.9.0714.12xx installed, Steam live): the manager-created pad (index 1) enumerates with per-pad serial PFDK50460001, Steam logs Interface: 2 -> '!! Steam controller device opened' -> 'Steam Controller reserving XInput slot 0' -> PollState 2 (actively polling our cycling input frames) -> mapping activated; clean teardown on exit. Rumble round-trip through a real game remains an on-glass debt (nothing sent 0xEB during the idle hold). Known gap vs Linux: no physical-Steam-controller conflict degrade on Windows yet (degrade_steam_on_conflict is Linux-only — /sys scan); a Windows equivalent needs SetupDi enumeration and is deferred.

enricobuehler	8c854e0a19	feat(gamepad): classic Steam Controller backend — Linux UHID via hid-steam (N3) ... The reserved GamepadPref::SteamController = 5 slot goes live: the same hid-steam driver under the wired-SC identity (28DE:1102, ID_CONTROLLER_STATE), UHID-only in v1 (no captured SC USB interface layout, so no Steam-Input promotion — the pre-usbip Deck state; acceptable for discontinued hardware). Layout pinned against the kernel's ID_CONTROLLER_STATE table: 24-bit buttons at 8..11 (low bits shared with the Deck; grips at 9.7/10.0 = the Deck's L5/R5 positions; right-pad click 10.2; joystick click 10.6), u8 triggers at 11/12, the joystick/left-pad MULTIPLEX at 16..20 (a left-pad contact shadows the stick, like real hardware's lpad_touched flag), right pad at 20..24. Mapping: wire left stick -> SC stick; wire right stick -> right-pad coords + touched bit (the SC's camera surface — the second-stick loss is inherent); PADDLE1/2 -> the two grips (natively, masked out of the fold input); PADDLE3/4 + MISC1 -> the remap policy. The SC parser has NO gamepad_mode gate, so no mode-entry pulse. SteamDeckPad grew a SteamModel (open_model); ScProto/SteamCtrlManager; pick_gamepad flips SteamController -> itself on Linux (replacing the Xbox360 fold); SDL picker splits Valve PIDs (Deck 1205 stays SteamDeck, SC 1102/1142 now declare SteamController). Verified: .21 clippy -D warnings + 304/0 tests + on-box UHID smoke (hid-steam binds 1102, BTN_A + right-pad ABS_RX land on evdev, no mode pulse); .133 clippy -D warnings green.

enricobuehler	8a18e130a2	feat(client): freeze-until-reanchor loss recovery on Android + Apple via shared core gate ... After unrecoverable loss the host keeps sending delta frames that reference a picture the client never received; hardware decoders conceal these as gray/ garbage with a success status. Linux already withheld them and held the last good frame until a proven clean re-anchor — this brings that behavior to the Android and Apple clients. Extract the Linux pump's freeze state machine into a shared `ReanchorGate` in punktfunk-core (reanchor.rs, 18 tests) exposed over the C ABI (ABI v6, additive — no wire change) for the Swift clients. Migrate the Linux/Deck pump (pf-client-core) onto it as the parity proof (no-op refactor). Then wire: - Android (decode.rs, both sync + async loops): arm on the frame-index gap, a pts-keyed flag map carries the wire flags to the output-buffer release, fold the gate per drained output, gate.poll replaces the dropped-climb block. - Apple Stage2Pipeline (default): arm on a gap (new noteFrameIndexGap), withhold at the ring-submit seam (CAMetalLayer holds its last drawable), poll framesDropped, fold VT decode errors through the no-output streak. - Apple StreamPump (stage-1): fold at enqueue, withhold via kCMSampleAttachmentKey_DoNotDisplay so the layer keeps decoding (reference chain intact) but holds the last displayed frame. - Apple VideoDecoder: thread the AU's wire flags to the async decode callback via a retained FrameContext refcon (replaces the receivedNs bit-pattern scalar). Lifts only on a proven re-anchor (IDR / RFI anchor / 2nd recovery mark) with a 500 ms backstop so a lost re-anchor can never freeze forever. Apple: swift build clean, 123/123 tests pass (incl. VideoToolboxRoundTripTests). On-glass loss-injection validation still owed. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-07-13 01:22:09 +02:00
enricobuehler	76be4c3e12	feat(gamepad): multi-controller support on the native plane ... Host was already built for 16 pads; the blocker was every client hard-coding pad 0. This lands the host-side + reference-client contract: - input.rs: new wire kinds GamepadArrival=14 (declares a pad's type: code=GamepadPref byte, flags=pad) and GamepadRemove=13 (flags=seq<<24|pad, shares the snapshot seq space via encode/decode_gamepad_remove). - pf-client-core/gamepad.rs: reworked from a single `open` pad to a slots: Vec<Slot> model — every forwarded controller gets a stable lowest-free wire index held for its lifetime, per-slot held/axis/touch/ rumble state, GamepadArrival on open + GamepadRemove on close, and feedback routed back per wire index. Automatic forwards all real pads; a pin forces single-player. - punktfunk1.rs: replaced the single-session PadBackend enum with a Pads router — per-pad kinds[]/owner[] arrays, lazily-created per-kind managers, pure route_decision keeping a live device in its manager across a kind change (no ghost/dup). Input thread seq-gates GamepadRemove (clears the pad_mask bit, resets rumble) and applies GamepadArrival kinds. - inject linux/windows backends: add the two new no-op InputKind arms. Native/session + default-Windows clients (both spawn punktfunk-session) inherit this. 57 core + 33 client-core + 272 host tests green; clippy clean.

enricobuehler	fdda7144ed	fix(encode): harden loss-recovery correctness across host encoders (F1–F7) ... Phases 1–4 of design/encoder-recovery-hardening.md — make the shipped RFI/ freeze-until-reanchor recovery honest and rebuild-safe across every backend. F1 — frame-index domain desync: the encode loop now owns a session-lifetime `au_seq`; `Encoder::submit_indexed(au_seq + inflight)` pins NVENC inputTimeStamp and AMF LTR slots to the WIRE frame index, so `invalidate_ref_frames` compares client frame numbers in the same domain and survives adaptive-bitrate rebuilds (an internal counter desynced on the first rebuild → RFI silently dead / an AMF force-ref onto a never-decoded frame). `FrameMsg.frame_index` → `Session::seal_frame_at`; GameStream gets the same via `VideoPacketizer:: packetize(.., Some(idx))`. F2 — Windows NVENC left the client frozen ~1s per loss: NVENC RFI was transparent (no anchor tag) while the session glue armed the 750ms IDR cooldown, so the freeze only lifted on the ~1s keyframe re-ask. NVENC now mirrors AMF — `pending_anchor` tags the first post-invalidate AU (the clean re-anchor P-frame) `recovery_anchor`, incl. the covering-range dedupe re-arm; the client lifts at ~RTT. F3 — speed-test probe filler burned video frame indexes: moved to its own index space (`Packetizer::alloc_probe_index` + `Session::submit_probe_frame`) with a second client reassembly window routed on FLAG_PROBE, gated on the new VIDEO_CAP_PROBE_SEQ Hello bit (mid-session probes declined for older clients). F4 — RFI range sanity cap: forward gaps wider than `packet::RFI_MAX_RANGE` (256) resync via keyframe instead of an out-of-range RFI, host- and client-side (client huge-gap → keyframe in `RfiRecovery::observe` + the pf-client-core pump). F5 — reset() parity: Windows NVENC (teardown + lazy re-init), Linux VAAPI (drop-inner), Linux NVENC (reopen from stored OpenArgs) now give the stall watchdog a heal lever instead of ending the session. F6 — sw.rs `pending: VecDeque` (was `Option`), killing the silent AU drop at capturer pipeline depth > 1. F7 — doc sweep on the RFI/anchor comments. Verified: punktfunk-core lib tests (macOS + Linux), full punktfunk-host suite on Linux (RTX 5070 Ti), Windows compile.

enricobuehler	7cea893db5	feat(recovery): wire LTR-RFI loss recovery into every client ... Centralize the client-side loss-range detector in punktfunk-core so every embedder shares one implementation instead of re-deriving the wrapping frame-index arithmetic: - NativeClient::note_frame_index(frame_index) folds each received AU (in receive order) through RfiRecovery::observe, firing a throttled RFI request for the exact lost span [first_missing, frame_index-1] on a forward gap. A host that can RFI (AMD LTR / NVENC) re-references a known-good frame instead of paying a 20-40x IDR spike; the frames_dropped-driven keyframe path stays the backstop for when the recovery frame itself is lost. - Export request_rfi + note_frame_index over the C ABI (Apple client). - Call it from the Android (hw+sw pumps), Apple (StreamPump + Stage2Pipeline via PunktfunkConnection.noteFrameIndex), and Windows in-process pumps. Linux/Deck inherit it through pf-client-core's session pump. - Split the decision into a pure RfiRecovery::observe(frame_index, now) and add 8 unit tests: arming, contiguous runs, exact lost-range, single-frame drop, the 100ms throttle (burst-suppress then re-open), reorder stragglers, and u32 wraparound (contiguous + gap-range).

enricobuehler	e55ff1bb28	feat(recovery): clean mid-stream loss recovery — freeze-until-reanchor + AMD LTR-RFI ... Removes the "gray frames with motion" artifact on Vulkan-Video clients and lets AMD/NVENC hosts re-anchor after loss WITHOUT a 20-40x IDR spike. Client (pf-client-core): after a reference loss the hardware decoder conceals the missing-reference deltas (on RADV, a gray plate with new motion painted over) and returns Ok. The pump now freezes on the last good picture until a clean re-anchor instead of showing the concealment — lifting on a real IDR, an intra-refresh recovery mark (2nd wave boundary), or an LTR-RFI recovery anchor (1st). The frame_index gap is the early, precise loss signal and drives an RFI request. Host recovery signals (inert unless the backend supports them): - USER_FLAG_RECOVERY_POINT — intra-refresh wave boundary (NVENC constrained GDR). - USER_FLAG_RECOVERY_ANCHOR — AMD LTR reference-frame-invalidation recovery frame. AMD LTR-RFI (encode/windows/amf.rs) — the AMD twin of NVENC RFI. AMF's AVC/HEVC API has no constrained-intra property (intra-refresh cannot heal; PSNR-proven), so the only clean-recovery lever is user LTR: mark frames as long-term references, and on loss force the next frame to re-reference the newest known-good one — a clean P-frame, not an IDR. Two rotating LTR slots, ~0.5s mark cadence, on by default for AVC/HEVC (PUNKTFUNK_NO_AMF_LTR disables). invalidate_ref_frames picks the newest LTR before the loss; a range older than the live slots falls back to a keyframe. Protocol (punktfunk-core): RfiRequest control message + NativeClient::request_rfi(). Host: RfiRequest dispatch -> invalidate_ref_frames (IDR fallback); an RFI success anchors the keyframe cooldown so the client's frames_dropped echo of the same loss is coalesced away rather than emitting a redundant IDR. Spike: synthetic NV12 GPU source for headless AMF encoder testing. Validated: core rfi_request_roundtrip; pf-client-core 31 unit tests (incl. an_rfi_anchor_lifts_immediately); punktfunk-host builds + 271 tests on Linux; punktfunk-host builds clean on Windows; real AMD iGPU spike (invalidate at frame 90 forced re-reference to LTR frame 60 — 180 frames, keyframes=1, no recovery IDR).

enricobuehler	73c911cae4	feat(rumble): host-authoritative self-terminating envelopes (0xCA v2) ... Rumble was level-triggered, unbounded state on a lossy channel: a non-zero level meant "buzz until further notice", healed only by the host re-sending state every 500 ms, and every client guessed when the host had died with its own magic timeout (SDL 1.5 s, Apple 1.6 s, Android up to 60 s). A lost stop, a reordered start, or a dead host could drone the motor for seconds. Make "stuck rumble" inexpressible on the wire. The 0xCA datagram grows a length-tolerant tail — [u8 seq][u16 ttl_ms] — so it self-terminates: the host authorizes a level for at most ttl_ms and renews it (~120 ms) while it holds, letting an abandoned one lapse client-side. seq is a per-pad wrapping reorder gate (reusing GamepadSnapshot::seq_newer) so a reordered stale start can't re-light a stopped motor. Decoders read the first 7 bytes as a plain level and ignore the tail, so no wire-version bump: an old client renders a new host's levels, and a new client falls back to its prior staleness heuristic against an old host (ttl = None). All four generation pairings render correctly. - core: encode_rumble_datagram_v2 / decode_rumble_envelope (datagram.rs); the client demux applies the seq gate then forwards (pad, low, high, Option<ttl>); next_rumble is unchanged (drops ttl), next_rumble_ttl keeps it; ABI adds punktfunk_connection_next_rumble2 + PUNKTFUNK_RUMBLE_NO_TTL, ABI_VERSION 4->5 (WIRE_VERSION unchanged — the tail is backward-compatible). - host (punktfunk1.rs): the flat 500 ms refresh becomes a renewal loop that bumps seq + stamps a fresh TTL on active pads and drains a short post-stop zero burst, then goes quiet. Hatches: PUNKTFUNK_RUMBLE_ENVELOPE=0 (legacy v1 + flat refresh, a bisect switch), PUNKTFUNK_RUMBLE_TTL_MS (clamped [150, 5000]). - renderers honor the TTL as their playback duration/deadline and keep their old heuristic only for a legacy (ttl=None) update: pf-client-core (the Deck haptic keep-alive is now deadline-bounded so it can't sustain a host-stopped rumble), clients/windows (SDL duration), android (JNI packs the lease out-of-band in bit 48 so any u16 ttl is unambiguous; Kotlin createOneShot(ttl)), apple (RumbleRenderer.envelopeDeadline + nextRumble2; sessionStaleSeconds demoted to the legacy fallback). - tests: codec round-trip + tail tolerance + seq-gate reorder (Rust); the probe asserts the v2 tail arrived under PUNKTFUNK_TEST_FEEDBACK; the Apple loopback asserts ttlMs round-trips end to end; RumbleTuning lease-decision cases. The host-side idle-timeout from the previous commit is defense in depth on the game side; this is the guarantee on the client side. Design: punktfunk-planning/design/rumble-envelope-plan.md.

enricobuehler	35d97ae6ac	feat(windows): parallel virtual displays — proto v3 ring binding, manager slot map, group topology (W0–W3) ... design/windows-parallel-virtual-displays.md (display-management Stage 7 / §6.6): N simultaneously-live pf-vdisplay monitors, one sealed ring each, every idd-push-security invariant preserved per-ring. - proto v3: SharedHeader._pad → target_id — the ring NAMES its monitor, host-stamped before the magic; the driver publisher refuses a cross-bound ring via the shared, unit-tested frame::check_attach (new DRV_STATUS_BIND_FAIL — the gamepad pad_index validation applied to frames, invariant #10); the host's wait_for_attach surfaces the refusal loudly and self-checks its own stamp. - manager: the one-monitor MgrState becomes a slot map keyed by the client's identity slot (0 = anonymous/GameStream); per-slot reconnect + dead-WUDFHost preempts, slot-scoped begin_idd_setup (a different identity is an admission question, never a preempt), ONE device-level watchdog pinger, per-slot /display/state + /display/release. - group topology: isolate_displays_ccd takes the managed target SET (a sibling slot is never deactivated); SavedConfig + the DDC/PnP axes move to the group record (first-in captures, last-out restores); desktop layout via CCD source origins from the pure layout::arrange (auto-row default, manual pins win), re-applied on create + reconfigure. - admission: the Windows separate→reject override now sits behind the PUNKTFUNK_WIN_SEPARATE=1 validation hatch (the wedge it guarded is structurally gone — a second identity gets its own monitor + ring; default flips in W5 after soak); max_displays and NVENC session-unit budgets decline an unaffordable display AT admission; kick_dwm_compose is process-globally throttled and per-display — cursor jump + 35 ms dwell (a sub-tick jump composes nothing; DWM reads dirties from current state at the next vsync tick). On-glass on the RTX box: V1/V2/V4/V5/V6/V9 green — two paired clients on two monitors streaming ~60 fps each with zero mismatches and zero bind failures, churn-hammer clean (no 0x80070490), per-ring mode-change recreate leaves the sibling untouched, typed budget rejection, fault-injected cross-bind refused loudly with the sibling undisturbed. V7: WUDFHost-kill shared fate is clean; in-process device recovery is a known follow-up (the retired-never-closed control handles block the adapter cycle — reset-pf-vdisplay.ps1 recovers). DWM composes two IDD monitors concurrently at 60 fps — the plan's load-bearing unknown, answered yes. Also carries the client-HDR EDID forwarding that shared this working tree (Hello::display_hdr → AddRequest luminance tail → the monitor's CTA-861.3 HDR block, PUNKTFUNK_CLIENT_PEAK_NITS hatch) and the Deck client fixes (40 ms rumble keep-alive with 1-LSB jitter, HDR self-diagnosing presenter warn, flatpak HDR env).

enricobuehler	3078528b28	feat(video): 4:4:4 defaults — the host allows it, the client chooses it ... Capability now lives on the host, choice on the client. PUNKTFUNK_444 flips to DEFAULT ON with an explicit-off grammar (0/false/off/no — the old presence-only flag() would have read =0 as on); every existing gate still applies (client advertisement, HEVC, full-chroma capture, encode probe, Windows HDR-display downgrade), so an unset host merely stops refusing. The Apple client's "Full chroma (4:4:4)" toggle flips to DEFAULT OFF: full chroma is a per-session trade — a clear win for desktop/text, but at a fixed bitrate game content spends those bits better at 4:2:0, and the encode/decode pixel rate rises. Persisted user choices survive both flips. Live-verified on the CachyOS VM: host with no env negotiates chroma_format_idc=3 for a 4:4:4-advertising client; PUNKTFUNK_444=0 resolves 4:2:0.

enricobuehler	db49904c6d	fix(core): un-break win64 clippy — RawSocket is already u64, the cast is same-type ... CI's Windows clippy (-D warnings) rejects `raw as u64` in the qWAVE flow guard: std's RawSocket is u64 on Windows, so the cast is a no-op (clippy::unnecessary_cast). Verified with the CI's exact invocation (cargo clippy -p punktfunk-host --features nvenc,amf-qsv -- -D warnings) on the RTX box.

enricobuehler	ddb93c533c	fix(core,android): networking-audit small follow-ups — bounds, oversized AUs, probe flag ... Networking-audit deferred plan §6: - 6.1 client reassembler ceiling derived from the negotiated rate: Welcome::session_config (client role) now sets max_frame_bytes to clamp(4 × bitrate_kbps×125 / refresh_hz, 8 MiB, 64 MiB) instead of the blanket 64 MiB p1_defaults bound — the hostile-header memory ceiling was ~10× larger than any real access unit. Local only (the host never reassembles video; the wire is self-describing); a bitrate-0 (older) host keeps the old bound. Unit-tested floor/derived/host/old-host cases. - 6.2 ProbeState.active is cleared when the host's ProbeResult lands, so the pump stops mirroring receive counters once the burst is over. - 6.3 Android: an AU larger than the codec input buffer is DROPPED with a recovery-keyframe request and a counter, on both the sync (feed) and async (feed_ready) paths — a truncated AU is corrupt input the decoder chews on silently, poisoning the reference chain until the next IDR. The async path recycles the never-queued input slot; the sync path returns the dequeued slot with zero valid bytes. - 6.4 bounded uplink channels: mic_tx at 64 (~320 ms of 5 ms frames; overflow sheds the fresh frame with a debug log — a tokio mpsc can't shed from the head, and past 320 ms of backlog the mic is broken either way; the bound is about memory) and ctrl_tx at 32 (sparse requests; a full queue means a wedged control task, reported as Closed). input_tx stays unbounded per the plan: keyboard/mouse events must never silently drop, and gamepad state is snapshot-healed. - 6.5 (wire version byte says P1 while streaming Gf16): record-only, resolves with the P2 packet revision. include/punktfunk_core.h: cbindgen re-emitted in the new module order after the quic/ split (item 3) — no semantic change beyond the reorder. cargo ndk check (arm64-v8a), workspace clippy, core+host tests green.

enricobuehler	9afcbcd307	feat(transport): Windows DSCP via qWAVE flows — PUNKTFUNK_DSCP now real on the wire there ... Networking-audit deferred plan §4 (the qos.rs follow-up). On Windows set_tos_v4 succeeds but the stack strips the mark without a qWAVE flow, so PUNKTFUNK_DSCP=1 was a silent wire no-op there. Now (Apollo/Sunshine's approach): QOSCreateHandle once per process; QOSAddSocketToFlow per connected media socket — video → QOSTrafficTypeAudioVideo, audio → QOSTrafficTypeVoice (QOS_NON_ADAPTIVE_FLOW) — then best-effort QOSSetFlow(QOSSetOutgoingDSCPValue, 40/48) to pin the exact CS5/CS6 the other platforms mark. The pin lands for elevated processes (the host runs as the SYSTEM service — exactly where the video egress is) or under the "allow non-admin DSCP" policy; otherwise the traffic-type default marking stands (still WMM-useful). Gating + contract unchanged: opt-in via dscp_enabled(), every step debug-logs and continues. set_media_qos now returns an RAII QosFlow guard (QOSRemoveSocketFromFlow on drop) that must outlive the socket's traffic: stored in UdpTransport (declared before the socket, so drop order removes the flow first) and held for the stream's scope by the GameStream video/audio senders — whose tagging moved after connect(), since qWAVE derives the flow's 5-tuple from the connected socket (behavior-neutral on Linux). Off-Windows the guard is inert and never constructed. Validated: cargo check -p punktfunk-core --target x86_64-pc-windows-msvc green (the full host can't cross-check from Linux — aws-lc-sys needs MSVC tooling; it builds on-box via deploy-host.ps1). Remaining on the next Windows pass per plan: deploy to the RTX box and pktmon/Wireshark the client side — DSCP ≠ 0 on video egress with PUNKTFUNK_DSCP=1, 0 without.

enricobuehler	e9b2eacf87	refactor(core): split quic.rs (3.2k lines) into src/quic/ — pure move ... Networking-audit deferred plan §3. One file per concern, zero logic edits: quic/mod.rs MAGIC/CTL_MAGIC + re-exports (every crate::quic::X path compiles unchanged across host + all clients) quic/msgs.rs Hello/Welcome/Start, typed control msgs + type bytes, resolve_codec, ColorInfo, window_loss_ppm, pairing msgs quic/pake.rs the SPAKE2 pairing exchange quic/datagram.rs 0xC9–0xCF plane codecs (audio/rumble/mic/rich-input/ hidout/HdrMeta/HostTiming) quic/io.rs length-prefixed stream IO quic/clock.rs clock_offset_ns estimator, clock_sync, ClockResync quic/endpoint.rs quinn config, ALPN, pinning verifiers, keep-alive quic/tests.rs the cross-cutting test module, unchanged Mechanical deltas only: the nested `pub mod` wrappers became files (one dedent), submodules import what they previously inherited from the parent scope, and the three RichInput kind tags are pub(super) for the tests (same-module before). Verified line-multiset-identical after normalizing indentation. cargo check --workspace, core tests (quic), clippy, and cargo ndk check all green.

enricobuehler	d4467a44e2	feat(core): mid-stream clock re-sync — live offset survives wall-clock steps and drift ... Networking-audit deferred plan §2. The host↔client offset was measured once at connect; an NTP step or slow drift silently corrupted the clock-based jump-to-live signal, the ABR one-way-delay signal, and every latency stat — 4a3b1ae2's disarm backstop stopped the IDR storm but lost the detector for the session. Now the client re-estimates mid-stream and recovers it. - quic: ClockResync — the connect-time 8-round probe/echo estimate as a select!-driven state machine (rounds matched by echoed t1, stale batches ignored), plus accept_resync (batch min-RTT ≤ max(2 ms, 1.5× connect RTT) so a congested window can never bias the offset). No wire change: the host has always answered ClockProbe at any time on the control stream. - client: the offset lives in an Arc<AtomicI64> seeded at connect; the control task re-probes every 60 s and immediately after the pump's FIRST no-op clock flush (the "clock stepped under me" signal, sent on the next report tick). On apply: store, reset stale_frames/noop_clock_flushes, re-arm the clock detector if a step had disarmed it. The disarm heuristic stays as the final backstop. Public NativeClient::clock_offset_ns keeps the connect-time value (ABI untouched); new clock_offset_now_ns() / clock_offset_shared() expose the live value. - consumers migrated to the live offset: pf-client-core session stats, the pf-presenter e2e stamp, Windows session/render, Android feeder/drain/ DisplayTracker (the tracker holds the shared handle, not the client, so the leaked render-callback refcount can't pin the session). - probe: --clock-resync runs a second full handshake mid-connection and asserts a sane, consistent estimate. Live against the local canary host: offsets 8646/2139 ns, disagreement 6 µs, 8/8 rounds — OK. Unit tests cover the round collection, stale-echo rejection, batch restart, min-RTT selection, and the acceptance guard. cargo ndk check green. Remaining manual validation: `sudo date -s "+2 sec"` on a live streaming client → expect one no-op flush, a re-sync, re-armed detector, no IDR pulse.

enricobuehler	68a863866a	perf(core): packetize straight into the wire pool — zero-alloc host send path ... Stage B of the zero-copy host packetize path (networking-audit deferred plan §1): Packetizer::packetize_each yields (header, shard) pairs in exact wire order; Session::seal_frame writes seq(8) ‖ header(40) ‖ shard ‖ tag scratch directly into the pooled wire buffer and seals [8..] in place. The per-packet intermediate Vec (header ++ body) and its extra memcpy are gone — with Stage A, every data byte is now copied once (frame → wire) instead of three times, and the ~2 transient allocs/packet on the send thread are zero after pool warmup (~180k allocs/s at 1 Gbps rates). packetize() stays as a thin wrapper over packetize_each — the reference implementation used by tests and the loss harness. - wire-equivalence test: pooled path vs wrapper path byte-identical across multi-block/partial-tail/exact-multiple/empty frames, fec 0%/50%, both schemes, crypto on/off - loss-harness sweep: recovery rates identical to the pre-item-1 baseline - bench pipeline (end-to-end incl. client half) vs pre-item-1 baseline, stages A+B cumulative: gf16/64K -3.6%, gf16/1M -3.2%; gf8 cases are Cauchy-math-bound and unchanged within noise - cargo ndk check (arm64-v8a) green Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-10 15:22:53 +02:00
enricobuehler	cdbdc078d6	perf(core): ref-based FEC encode — packetize shards reference the frame in place ... Stage A of the zero-copy host packetize path (networking-audit deferred plan §1): ErasureCoder::encode now takes &[&[u8]], so Packetizer::packetize builds each block's data shards as slices straight into the frame buffer instead of allocating + copying a Vec per data shard. Only the frame's final (possibly partial) shard is staged in a reusable zero-padded scratch; blocks are consecutive shard ranges, so every other shard is a full payload-sized slice. - gf8: encode_sep() over the same Cauchy codec — parity byte-identical to nanors/Moonlight (nanors_exact_parity_vectors unchanged and green) - gf16: reed_solomon_simd::encode is already generic over AsRef<[u8]> - loss-harness sweep: recovery rates identical before/after - bench pipeline (end-to-end, host+client): gf8/64K -3.0%, gf16/64K -2.2%, gf16/1M -3.4%, gf8/1M -0.7% Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-10 15:16:07 +02:00
enricobuehler	204577c7ce	style(core): dedupe Hello::decode trailing-field offset math ... The four trailing single-byte fields (video_caps, audio_channels, video_codecs, preferred_codec) each recomputed the name/launch offset chain from scratch — four copies of the same three-line walk, each a chance to diverge when the next trailing field lands. Compute name_len/launch_off/tail once and index from there; name/launch decode from the same bindings. Wire behaviour pinned by the existing roundtrip + back-compat tests (all green).

enricobuehler	6fbab53d56	feat(audio): libopus packet-loss concealment on the client audio plane ... The 0xC9 audio datagrams ride the lossy plane with no FEC, and no client ever consulted the per-packet sequence: a lost 5 ms Opus packet played out as a hard gap in the ring — an audible click/pop on every drop, i.e. constantly on the Wi-Fi links where video loss is already being FEC-absorbed. Now a shared `AudioGapTracker` (punktfunk-core::audio — pure data, wrap-safe, unit-tested incl. u32 wraparound / reorder / duplicate cases) tells the decoder how many packets went missing immediately before each received one, and both native clients (pf-client-core PipeWire path, Android AAudio path) synthesize that many frames of libopus packet-loss concealment first: `decode` with empty input (the opus crate maps it to a NULL data pointer = PLC), sized by the last real frame's sample count. Interpolated fade instead of a click. Bounds: a gap is capped at 10 packets (50 ms) — libopus PLC fades to silence after a few frames anyway, so past the cap the rings' existing underrun/re-prime path takes over. Reorders and duplicates conceal nothing (the plane has no reorder buffer; playing a late packet where it lands is the existing behaviour). In-band Opus FEC (LBRR) is deliberately NOT used: the host sends 5 ms frames and LBRR needs ≥10 ms frames to carry anything. The cap is a crate-private const so cbindgen keeps it out of the C ABI header. Host cargo tests + clippy green; android crate verified via cargo ndk check.

enricobuehler	4a3b1ae2e3	fix(core): jump-to-live survives a mid-session clock step — disarm on no-op flushes ... The clock-based jump-to-live detector compares wall-clock receive time against the CONNECT-TIME skew offset. A wall-clock step on either end (NTP mid-session, resume-from-sleep correction) shifts every future frame's apparent latency by a constant: past the 400 ms bound the detector fires forever — one backlog flush + recovery IDR every 2 s cooldown, and the bitrate controller rides the repeated "flushed" bad windows down to its floor. A stream that was perfectly live turns into a periodic quality pulse with no recovery path. The tell is in the flush itself: a genuine 400 ms backlog is ≥~170 datagrams even at the 5 Mbps bitrate floor, but a clock-step flush finds nothing to discard. So: two consecutive clock-triggered flushes that discarded <64 datagrams and zero queued AUs disarm the clock detector for the session (logged). This also covers upstream router bufferbloat — delay standing in a queue a local flush can't drain, where the OWD signal to the bitrate controller is the actual remedy and a 2 s IDR cadence only feeds the congestion. The clock-free queue-depth detector stays armed either way; it measures the local queue directly and can't be fooled by a clock. Rode along: the 11-field `Negotiated` tuple is now a documented struct — the connect/worker plumbing reads as named fields instead of positional magic.

enricobuehler	c7b8007ce7	fix(core): receive path — replay window covers the loss window, zero-alloc open ... Two receive-path findings from the networking audit: 1. The anti-replay window (4096 seqs) silently re-tightened the "late ≠ lost" fix: at 1 Gbps (~125k pkt/s) it spans only ~33 ms, so a Wi-Fi-retry-delayed shard the reassembler's 120 ms loss window would still use was dropped HERE first as "older than the window" — recreating the false-loss → recovery-IDR churn the time-based loss window was built to kill, exactly on the high-rate links punktfunk targets. Widened to 32768 (covers 120 ms up to ~270k pkt/s, ≈2 Gbps+); the bitmap costs 4 KiB per session and the replay-hiding bound stays finite. 2. Every received datagram still paid one Vec allocation in the AES-GCM open (and a to_vec on the plaintext probe path) — ~125k allocs/s of cross-thread allocator churn at line rate, the same class of overhead that was the documented single-core wall on the macOS receive path. New `SessionCrypto::open_in_place` (mirror of seal_in_place; GCM verifies the tag BEFORE decrypting, so a forged packet never yields plaintext) lets `poll_frame` decrypt inside the recv ring and hand the reassembler a slice. Byte-identical semantics, unit-tested against `open` incl. tamper/runt cases; criterion entry added next to seal_in_place. Tests: 94 core unit + loopback/c_abi suites green; clippy clean.

enricobuehler	e707a962b6	fix(security): anti-replay, 0600 client key, open redirect, supply-chain ... Address findings from a repo security review: - core: add a sliding-window anti-replay filter over the AEAD-authenticated sequence in Session (poll_input/poll_frame), closing the input-replay gap the data plane previously left to the LAN/VPN trust assumption. 4096-deep window, unit-tested; the encrypted loopback suite confirms no false drops. - clients: write the mTLS client private key 0600 and lock the config dir 0700 on Unix (it was world-readable at the umask default), re-locking existing stores on load. pf-client-core::trust plus the probe's own identity writer. Windows keeps the %APPDATA% ACL; Android/Apple already wrap the key. - web: fix a post-login open redirect — resolve `next` via URL and require it to stay same-origin, rejecting `/\evil.com` and tab/encoding variants the old `!startsWith("//")` guard missed. Also fixes the dead safeNextPath helper. - ci: SHA-256-pin the BtbN FFmpeg DLLs bundled into the signed Windows installer (were fetched from the rolling `latest` tag unverified); fails closed on a re-roll, matching the VB-CABLE gate. - ci: fail-open fork-guard on the Windows/Apple host-mode PR build jobs that share runner labels with the signing jobs. Definitive fix stays server-side (Gitea outside-collaborator approval / isolated PR runners) — see the notes. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>	2026-07-10 10:04:23 +02:00
