enricobuehler	b31495bea5	fix(host): a leftover Sunshine folder is not a conflict, and a crashed host gives the screen back ... Three things a field report (Discord, upgrade from 0.1x) turned up, all on the Windows host. 1. "It thinks I have Sunshine/Apollo running." It didn't — they were uninstalled. Both uninstallers leave their config/log directory in Program Files behind, and `detect.rs` counted a bare directory, or a service registered at ANY start type (including `disabled`), as a live conflict. The installer's own probe was narrowed to "service start type <= 2" after exactly this cried wolf on a `winget install`, and the tray dropped its always-on warning for the same reason in 3e782852 — the runtime probe never got the same treatment, so the one surface the user actually looks at kept shouting. `Evidence::is_active` now draws the line (running, or set to start on its own) and only active detections reach the startup warning, the `detect-conflicts` exit code, and `/local/summary`. Dormant findings still print in the full report, under a heading that says they need no action — that report is where "why does it think I have Apollo?" gets answered. 2. The console's conflicts card hardcoded "Another game-streaming server is **running** on this machine" regardless of what was found, so a dormant leftover was announced as a running server. It now says "active", and each entry names the observation — `Sunshine (running)`, `Apollo (starts automatically)`. 3. "The exclusive screen never times out going back to re-enabling the display." `isolate_displays_ccd` deactivates the operator's panels and hands the pre-isolate topology to the caller, which restores it at teardown — but that snapshot is PROCESS MEMORY, and Windows deliberately never saves the isolated topology to the CCD database. So a host that crashed, was killed, or was stopped mid-session left the desk dark with nothing in the product to undo it. There was one startup recovery leg already, but only for the EXPERIMENTAL `pnp_disable_monitors` axis, which is off by default — the default Exclusive path had none. `isolate_journal` now marks what an isolate is about to switch off (before the apply, so dying mid-apply is covered), clears the mark on restore, and force-EXTENDs at host startup if a mark survived. EXTEND rather than replaying the saved blob: the blob pins the virtual display's target id, which dies with the crashed host, so a replay would mostly fail BAD_CONFIGURATION into the very same backstop `restore_displays_ccd` already keeps — and EXTEND stays correct across a reboot, where saved ids would be stale.	2026-08-04 22:34:33 +02:00
enricobuehler	9f1f23eb40	Merge pull request 'feat(wire): mid-session shard-payload renegotiation — the black screen heals in seconds, jumbo behind an opt-in' (#41) from worktree-shard-payload-reneg into main ... Reviewed-on: #41	2026-08-04 18:06:41 +00:00
enricobuehler	34ad3cc611	feat(host/wire): mid-session shard-payload renegotiation, driven by the MTU verdict ... Phases 1-2 of design/shard-payload-reneg.md, on top of the Phase 0 per-frame geometry. The leg-1 watcher stops merely diagnosing the constrained path and heals the CURRENT session; the same machinery, inverted, takes a proven jumbo LAN up to ~8.9 KB shards. - Messages: MSG_SHARD_PAYLOAD_CHANGED (0x08, host→client, {shard_payload u16}) and MSG_SHARD_PAYLOAD_ACK (0x09, the echo). Asymmetric by design: a shrink re-keys the packetizer at the next AU immediately after sending (per-frame pinning makes ordering irrelevant; the ack is telemetry), a grow emits nothing above the old size until the ack — the ack is the gate even though client buffers are statically sized. - Client: one dispatch arm in the shared pump control task (all client families) — validate against the advertised receive bounds, ack; out-of-bounds requests get SILENCE, not an ack, so a buggy host can never read a granted grow out of garbage. - Host driver: the wire_mtu watcher grows a ShardReneg arm — on a below-ceiling verdict it still records the learned budget (session 2 starts right) and now also shrinks session 1 at the ~3-10 s verdict mark; with the jumbo opt-in (PUNKTFUNK_JUMBO=1, or PUNKTFUNK_WIRE_MTU > 1500 — one knob, derived) it sends the ack-gated grow after a settled-at-sealed-jumbo proof and then stays alive as the revert guard: quinn's blackhole detection lowering current_mtu shrinks the wire back through the same path. The QUIC MTUD probe ceiling rises from 1472 to the sealed jumbo size with the opt-in (per-ENDPOINT: a few extra failed probes toward non-jumbo peers, zero cost otherwise). - Apply point: Session::set_shard_payload drained in the send loop next to the adaptive-FEC target, gated on no open streamed AU (a streamed frame's shard-aligned tiling derives from the size it began with). - Renegotiation is gated OFF for PyroWave sessions: their clients parse chunk-aligned AUs in windows of the Welcome value pinned at session start (read once over the C ABI), so a mid-stream re-key would corrupt the parse — those sessions keep the leg-1 next-session clamp. This also settles the plan's open question on the two wire_chunk consumers: both are PyroWave-only, so the gate covers them entirely. - Legacy peers are inert both ways: no Hello advertisement → the host never constructs the driver; an old host never sends the message. core: 296/296 --features quic + clippy -D warnings (macOS), fmt; the regenerated header carries the new message ids (drift gate).	2026-08-04 19:42:36 +02:00
enricobuehler	69f1db5ea9	Merge pull request 'feat(host/wire): MTU resilience for the video data plane' (#37) from worktree-wire-mtu-resilience into main ... Reviewed-on: #37	2026-08-04 17:02:01 +00:00
enricobuehler	4bc7eecf05	feat(host/wire): MTU resilience for the video data plane ... Video datagrams are sealed at a shard payload sized for a clean 1500-byte MTU (1472-byte UDP payloads). A host whose route to the client crosses a smaller-MTU hop (a VPN/overlay adapter claiming the LAN route, a lowered NIC MTU) delivers every small flow — QUIC control, hole punch, input, audio — while 100% of video datagrams die: the client sits on a black screen reporting zero loss and the host streams into the void with every gauge green. Field-reported as 'connects fine, black screen forever'. Three legs, none of which changes a session on a healthy path: - PUNKTFUNK_WIRE_MTU operator override: shard payload derived from a given on-wire IP MTU. Wire-compatible — Welcome::shard_payload is already negotiated per session (the v4/v6 split ships two values today) and every client follows the negotiated value. - Detection: the QUIC MTU-discovery probe ceiling moves from quinn's stock 1452 to exactly the sealed video-datagram size (1472), so a control connection's settled MTU becomes a verdict on the path: settled at the ceiling proves it carries video, settled below proves it cannot. A per-session watcher samples after the search has settled (live-connection guard against mid-search false learns) and logs an actionable WARN naming the failure shape and the diagnosis commands. - Healing: the measured budget is recorded per peer IP; the next handshake clamps shard_payload to fit, so a reconnect self-heals. A later session that reaches the ceiling erases the record. Verified: core 286/286 --features quic + clippy -D warnings (macOS); host clippy -D warnings + native:: tests 44/44 (pf-lxcheck container). The regenerated C header picks up the new MIN_SHARD_PAYLOAD constant.	2026-08-04 18:30:33 +02:00
enricobuehlerandClaude Opus 5	2cfc82e96c	fix(audio): budget the audio plane against the link, and close the review's gaps ... Findings from the post-implementation review of design/audio-quality-and-latency.md. **The bandwidth gap (highest).** Tier `High` (256 kbps) and the redundant `0xD2` plane were added separately, each costed as "~1 % of the video budget", and nobody added them together: 256 kbps sent twice is 512 kbps — ~2.5 % of a 20 Mbps session but ~10 % of a 5 Mbps one. Audio rides QUIC datagrams, OUTSIDE the ABR loop, so ABR could neither see that nor reclaim it; a constrained link quietly handed a tenth of its bandwidth to audio while ABR carefully managed the rest. `plan_audio_budget` now makes tier and redundancy ONE decision against the session's resolved video bitrate, ordered by preference rather than cost — transparent audio beats redundant audio, since the field report was about quality and redundancy only pays under loss, so `High` alone outranks `Standard`+redundancy even though they cost the same. It can lower what the operator asked for, never raise it, and never goes below `Low`: a stream with unintelligible audio is worse than one spending a few percent more. **The Linux host kept the exact defect fixed on Windows.** `let _ = tx.try_send(samples)` — silent, uncounted data loss, where the encoder concatenates across the hole, so every drop is a click AND a permanent shift of everything after it. WP0.2 turned out to be Windows-only and had not said so. Linux now shares `capture_policy::CaptureStats`: drops counted and warned, plus per-window peak/RMS/delivered%. A Linux audio report was until now exactly as un-triageable as the Windows one was on 2026-08-03. **Apple's WP0.3 was half-done** — `bufferedMS` was added and wired to nothing. The drain thread now logs buffer/target/underruns/sheds like the other three, from one locked snapshot so the numbers in a line describe the same instant. Also: the Linux "audio format negotiated" line now says WHICH mode produced it, because that changes what it is worth — in stream-sink mode the host owns the sink so the mix cannot have been narrowed upstream, but in legacy monitor mode a 16 kHz Bluetooth sink would still be reported as a clean 48 kHz through PipeWire's resampler, the same way WASAPI's autoconvert hid it on Windows. Reading the monitored node's own rate needs a registry lookup this stream does not do; recorded as an open gap rather than implied to be covered. Two stale docs: `audio_wasapi.rs` cited `clients/windows/src/audio.rs` (deleted) and still described the pre-shared-policy "prime to ~3 quanta" behaviour. And the Apple ring's `prefill:` parameter, dead since the depth moved into the ring, is gone. Verified: clippy --all-targets -D warnings on Linux (docker) AND Windows (runner .133, forced clean rebuild of punktfunk-host + pf-client-core); core 167 tests; host 57 audio tests on Windows; Android clippy count identical to pristine (6, all documented arm64 artifacts); Apple ring re-simulated. The host suite's `gamestream::stream::tests::sender_delivers_batches` fails under qemu — the recorded environmental flake, unrelated to audio, green on the earlier less-loaded run.

enricobuehlerandClaude Opus 5	3055e29ebb	feat(host/audio): make audio observable, fix the endpoint choice, raise the encode quality ... Phases 0-3 of design/audio-quality-and-latency.md, host side. **WP2.1 — the 2026-08-03 root cause.** The client-only loopback preference took Steam's Streaming *Microphone* render endpoint over real hardware unconditionally, because it is silent on the host. But that endpoint exists to carry remote VOICE, and nothing checked whether it could carry music: on the reporter's box it won all 31 loopback opens across 25 sessions while a clean AMD HD Audio endpoint sat idle, and the whole desktop mix went through it before reaching Opus. A silent sink now has to EARN its preference — if its mix format narrows the mix it drops below real hardware. It is still taken when nothing better exists (narrow audio beats no audio), but flagged so the capture side says why. `plan_with_formats` takes a probe rather than reading WASAPI, so all 26 wiring-plan tests still run on every platform. An unknown format counts as fine, which is asserted: `unknown_formats_reproduce_the_formatless_plan` proves a probe failure can never make the plan worse than it was before formats existed. **WP0.1 — log the endpoint's ACTUAL mix format.** Everything the old log printed ("48 kHz f32 channels=2") was our REQUEST; with `autoconvert` WASAPI converts silently from whatever the endpoint really runs. That is why a 3,600-line log filed over an audio-quality complaint contained nothing that could diagnose it. **WP0.2 — count what we drop.** The capture->encode handoff was a silent lossy `try_send`: a stalled encode thread lost chunks, the encoder concatenated across the hole, and nothing recorded it — a click plus a permanent shift of everything after. Now counted and warned, alongside per-window peak/RMS/delivered% so a quiet host, a broken endpoint and a stream we are damaging ourselves stop looking identical. **WP2.4 — stop the default-device tug-of-war.** In Assert mode the capture is bound to the planned endpoint EXPLICITLY, so a hijacked default changes only where apps render — the old full reopen tore the capture down for nothing. The field log shows the cost: something re-set the default every ~4 s and each round was a teardown, a wiring pass with IPolicyConfig writes, and an audible dropout — seven in sixteen seconds, one ending in a 2 s error backoff. Now: put the default back, keep the stream, and after four rounds in twenty seconds concede for a minute and say so once. **WP1.1/1.2 — encode quality.** Constrained VBR (the hard-CBR comment justifies itself with GameStream's audio FEC, which this plane does not have) and `AudioTier::High` by default: stereo 128 -> 256 kbps, ~1 % of a 20 Mbps session. GameStream's encoder is deliberately untouched — its FEC really does need fixed-size packets. **WP3.1 — redundant `0xD2` plane**, sent when the client asked for it. **WP2.2 — `audio.output_mode`** as a first-class setting (`client_only` / `host_and_client` / `follow_default`), superseding the two undocumented env vars, which stay honoured. The enum lives in pf-host-config, which is deliberately dependency-free, so the tier table stays in core where the codec knowledge is. `capture_policy.rs` is split out for the same reason `wiring_plan.rs` is: both encode field behaviour, so their tests must run on Linux CI, not only on a Windows box. That split immediately earned itself — `capture_stats_separate_silence_from_signal` caught RMS being divided by the FRAME count while summed over interleaved SAMPLES, which inflated it by sqrt(channels) and made a sine report an RMS equal to its own peak. WP4.5 (open the loopback at the minimum device period) is deliberately NOT done: in shared mode `IAudioClient::Initialize` cannot change the engine period at all, so it would be a no-op at best and a new failure path at worst. Recorded in the code. WP2.3 (force the parked endpoint's volume) is deferred — `wasapi` keeps IMMDevice private, so it needs new raw COM on a path this tree cannot compile, let alone test; its diagnostic half ships as the RMS line above. Verified: punktfunk-host + pf-host-config clippy --all-targets -D warnings and the audio test suite under Linux/docker (gate proven non-vacuous with a planted type error); 26 wiring-plan tests standalone; fmt. The Windows-only halves of wasapi_cap.rs and audio_control.rs are NOT compile-verified anywhere yet. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-08-04 09:02:12 +02:00
enricobuehler	3eab1e41df	Merge remote-tracking branch 'origin/main' into worktree-haptics-m1-rumble-seq	2026-08-03 19:47:32 +02:00
enricobuehler	48565c4e9e	fix(host/abr): stop pinning Automatic sessions, and tell the client when the rate moves ... Two host-side halves of the same sweep. **The cadence latch.** `cadence_degraded` — which makes the control task refuse bitrate CLIMBS — was latched true for as long as the session was escalated (adaptive capture depth or pipelined retrieve), independently of whether encode was still missing deadlines. The client cannot tell that refusal apart from an encoder's real ceiling: both arrive as a short `BitrateChanged`, and two identical ones latch a cap. Escalation needs ~20 net behind-frames, which a startup hitch supplies while the ABR is still in slow start at the 20 Mbps default — so one transient pinned the whole session there, long after the escalation had bought back the headroom it was for, and escaping cost +12.5 % per 60 s. An escalated session is still judged strictly (ANY net behind-frame keeps it flagged, where an unescalated one gets the full bucket), but being escalated no longer flags it by itself: escalating exists so cadence CAN be held, and once it is, refusing climbs refuses the thing that worked. The rule moves into `encode_behind_cadence` so it is stateable and testable. **The silent re-target.** `adopt_built_bitrate` publishes the rate a rebuilt pipeline actually opened at — `build_pipeline` re-resolves an Automatic rate whenever the source delivers a size the session did not negotiate, the mirrored-panel case — and the encoder's own clamp can land below what the control task already acked. Neither reached the client, whose controller keeps its own copy of that number as its climb base. A 1080p client mirroring a 4K panel therefore believed 20 Mbps while the host encoded 60, and its first climb computed from the stale base asked for 40: a re-target DOWNWARD, paying an encoder rebuild to get there. Both paths now push the applied rate to the control task, which sends `BitrateChanged` — the existing 9-byte message, which already means precisely this and which clients already handle arriving unprompted. No wire-format change, no capability negotiation, old clients unaffected. 2 host tests added.	2026-08-03 18:53:02 +02:00
enricobuehler	14502769e0	fix(host/input): rumble comes back when a controller does ... Unplug a pad mid-session and plug it back in, and roughly half the time it never rumbles again for the rest of the session. The removal arm restarted the pad's rumble sequence counter. The client's reorder gate does not restart: `rumble_last_seq` lives for the whole QUIC connection and has no reset path, so it still holds whatever the pad reached before the unplug. Restarting the host counter therefore hands the client a seq it has already seen, and its wrapping half-space compare drops every envelope until the counter climbs back past the stored value — up to 128 sends. Since the counter only advances on a level change or a ~120 ms renewal while a level is non-zero, that spans many separate rumble events, so it reads as a flaky controller rather than a clean outage. Whether it bites is decided by how much the pad rumbled beforehand, which is why it looks intermittent: a pad that never rumbled before the re-plug has `None` on the client side and always heals. The counter now survives, matching the sibling pad-state gate — whose comment eleven lines above already explains that a re-plug must arrive with a still- newer seq to be accepted. The three clears that actually end the stale lease move into `clear_pad_feedback`, whose signature deliberately has no seq parameter so the arm cannot regress by editing. Covered by a regression test that drives the real wire encoder and the real client gate, and asserts the pre-fix behaviour is genuinely rejected across the whole forward window, so it cannot pass vacuously. Found by the 2026-08-03 force-feedback sweep (B1/T5 — see the backlog in punktfunk-planning design/haptics-sweep-2026-08-03.md).	2026-08-03 16:57:11 +02:00
enricobuehlerandClaude Opus 5	442ea12b96	test(mgmt): pin the two things that would silently break plugin logging ... The runner holds the PLUGIN token and nothing else — on Windows its LocalService principal cannot read the admin one at all. `plugin_may_access` is an exclusion list, so `/plugins/logs` is reachable today only because it happens not to match `/ui-credential`. If that ever changed, plugin logs would go quiet in the console with no other symptom and no failing test. Now asserted on that lane directly. The second test covers ingest end to end through `GET /logs`: the `plugin:` target prefix the console's Host/Plugins filter keys on, the level coercion (an unranked level would sort as 0 and hide under every filter setting), a sourceless line being attributed to the runner rather than to nothing, the caller's timestamp surviving the trip, and an oversized batch being refused whole.

enricobuehlerandClaude Opus 5	365caa23be	fix(plugins): plugin output reaches the console's log page, and /tmp is no longer hidden from the runner ... A user could not get the VirtualHere plugin to use their VirtualHere client and asked, reasonably, where the logs were. There was no good answer, and the reason they were stuck turned out to be ours. **The runner could not see /tmp.** `punktfunk-scripting.service` set PrivateTmp=yes, which hands the unit a private tmpfs. But integrating with things already running on the box is the entire job of a plugin, and on Linux those talk over /tmp: VirtualHere's client IPC is the FIFO pair /tmp/vhclient + /tmp/vhclient_response, X11 is /tmp/.X11-unix. So the plugin launched the vendor binary happily and could then never reach the daemon behind it — while the same command worked perfectly in the operator's own shell, because that shell has the real /tmp. No config change could fix it, which is exactly the loop the report described. PrivateTmp is now off, with /tmp added to ReadWritePaths (which ProtectSystem=strict would otherwise make read-only). **Plugin logs now land in the console.** Plugins are not host child processes — the runner is a separate bun process that import()s each plugin in-process — so nothing they print passed through the host's tracing, and the console's Logs page could not show a single plugin line. The fallback was journalctl on Linux; on Windows the runner's scheduled task writes no log file at all, so a failing plugin was diagnosable only by stopping the task and re-running the runner by hand. Both mean shell access on the host box, which is what the console exists to avoid — and it left the one question a stuck user asks with no answer. So the runner now tees its output to POST /api/v1/plugins/logs, and those lines join the host's own ring under one cursor, targeted plugin:<name>. The console grows a Host/Plugins switch beside the level filter; an empty Plugins view says the thing that is actually usually wrong (the runner isn't running) rather than "adjust the filter". The shipper keeps stdout authoritative — journald and foreground output are unchanged whatever the host is doing — and is built so that logging can never hurt the thing being logged: it never throws into a caller, holds a bounded queue that drops oldest and then says how many, backs off when the host is away (a restart is normal), and re-sends a batch the host failed to take. Lines logged while a POST is in flight are kept, which cost one round to get right: the first version held its recursion guard across the await and silently dropped exactly the lines a busy plugin produces. Runner lines that report a failure (a refused unit file, a crashed plugin, a give-up) now go out at warn/error instead of all arriving as INFO, so the console's level filter means something for them.

enricobuehlerandClaude Fable 5	98e040fd01	fix(host/stream): the wire holds the session rate when the display outruns it ... PUNKTFUNK_VDISPLAY_HZ_MULT promises extra display refreshes without one extra frame on the wire, but the frame-driven trigger enforced its pace only as a per-gap floor: sleep to 0.9×interval, then wake on arrival. A source that always has a frame pending — the overdriven display under uncapped content — settled at 0.9-interval spacing, 1.11× the negotiated rate. That is the field report's 132 fps on a 120 fps session: ten percent more bitrate, encode and decode for frames a 120 Hz panel can only drop. A credit bucket (PaceBudget) now pins the long-run average at the pacing rate: credit accrues at one frame per interval of real elapsed time, capped at 1.25 frames of post-stall burst, and every submitted frame spends one. A grab may run early only against banked credit, so the 0.9 floor keeps its per-gap jitter headroom while the average cannot exceed the rate — and a source at or below it banks faster than it spends and is never delayed. Anchoring to real elapsed time also keeps the synchronous-encode overlap the arrival-anchored floor bought (the owed fraction absorbs a constant encode tail instead of stacking on top of it), and it cannot fight the phase lock's submit grid: both agree the period is the interval. The charge lives under the same guard as the gate — the legacy fixed tick paces by its own grid, and charging it without ever accruing would bank unbounded debt that stalls the loop if a rebuild later flips the capturer to arrival-wait. Verified on .25: native::stream tests 15/15 (three new PaceBudget tests), punktfunk-host 369/369, clippy -D warnings clean, fmt clean.

enricobuehlerandClaude Fable 5	5174a59832	fix(capture/kwin): a hidden cursor leaves the stream — KWin's id-0 meta is the hide ... Since the 0.22.0 cursor work (the seat-pointer park + the metadata composite), a KWin capture-model stream always has a cursor — and it never went away again: not in game, not in Big Picture, not with a controller in hand (field report, 2026-08-01). The host blended the arrow forever because pf-capture deliberately ignores SPA_META_Cursor id 0, and once `visible` latched true nothing on Linux ever cleared it. Two producer contracts meet on id 0, and one flag now carries which one a stream follows. KWin rewrites the cursor meta on EVERY enqueued buffer and writes id 0 whenever Cursor::isOnOutput says the pointer is not in this stream — which covers both a globally hidden cursor and a client null-cursor surface (empty geometry intersects nothing). There id 0 IS the hide, and honoring it is what lets a game hide the pointer mid-stream. Mutter only rewrites a buffer's meta when the cursor changed, so recycled buffers carry stale id-0 regions between damage frames — honoring those flickered the cursor off between hovers (on-glass round 5), and that path keeps its last-known-state behavior. The flag rides from the backend that created the output (correct for registry-pooled reuse too — a kept display only ever matches its own backend) through capture_virtual_output into the parser's CursorState. The portal-monitor path stays on the stale-meta contract: the only thing routed through it today is Mutter's HDR mirror. Verified on .25: pf-capture 45/45, punktfunk-host 369/369, clippy -D warnings clean (pf-capture, punktfunk-host, cursor-probe), fmt clean. On-glass KDE validation still owed.

enricobuehlerandClaude Fable 5	652abeb397	fix(host/audio): an unsatisfiable wiring plan waits for an endpoint change instead of hammering ... Field case 2026-08: the display isolate invalidated the only real render endpoint; the mic held the Steam Streaming Microphone, the Speakers were blacklisted, and the capture loop re-ran the full wiring pass — three IPolicyConfig SetDefaultEndpoint writes included — every 2 s for 8+ minutes, retrying a verdict that could never change. - wiring_plan: a plan with no loopback is a typed structural verdict (Wiring::loopback_unsatisfiable + an endpoint-set fingerprint); the dead leftover() tier (byte-identical to real_hw()) becomes a real last resort that accepts ONLY the Steam Streaming Speakers, flagged loopback_last_resort — a known-silent-loopback QUALITY risk, never the cable/VoiceMeeter echo CORRECTNESS risks. excluded_from_loopback stays untouched (judge_default's mid-stream snap-back semantics). - wasapi_cap: an unsatisfiable plan errors ONCE per topology with the render inventory, per-endpoint rejection reasons and only the remedies not already taken, then parks on a cheap enumerate-and-hash poll and re-plans the instant the set changes; transient failures get a real capped exponential backoff (2 s → 60 s, reset on success or set change); a last-resort capture re-plans on any set change and promotes the 30 s zero-packet breadcrumb to warn. - audio_control: the recording default is asserted only when the plan changed or the default drifted — set_default_endpoint fires all three SetDefaultEndpoint roles unconditionally, so the 2 s loop silently stomped any operator recording-device change; the "attach one, or let the host install the Steam Streaming pair" warn (already satisfied in the field case) is replaced by the same diagnosis. Verified: 19/19 wiring_plan tests (native rustc --test and the Linux CI image via docker); both Windows files type-check and clippy clean against wasapi 0.23.0 / windows 0.62.2 for x86_64-pc-windows-msvc via an xcheck-style stub harness (the in-tree target check dies in openh264-sys2's build script on macOS, as scripts/xcheck.sh documents).

enricobuehlerandClaude Fable 5	48511d1267	fix(abr): probe throughput is measured over the client's receive interval ... The capacity probe divided client-side bytes by the HOST's burst duration — a window wrong on both edges (base snapshotted before the burst reached the host, frozen only when the ProbeResult landed, while the host's clock stops the moment ITS send window closes, before the switch/kernel queue finishes draining toward the client). On a 1 GbE link a 2 Gbps burst target "measured" 1266 Mbps and set an 886 Mbps climb ceiling the link could never carry — permanent for the session, because set_ceiling never lowers. The reassembler now stamps probe-scoped counters (bytes, packets, first/last arrival, monotonic ns) at its FLAG_PROBE routing, so video around the burst contaminates neither numerator nor denominator; the throughput divisor is the client's first→last arrival interval, with the host duration kept as the fallback when fewer than two probe packets arrived. The user-facing speed test shares the corrected computation (ProbeOutcome/PunktfunkProbeResult layouts unchanged; elapsed_ms docs updated to the new semantics). Two guards ride along: - PUNKTFUNK_ABR_MAX_MBPS clamps inside set_ceiling — the one funnel every learned ceiling passes through — so a user cap binds no matter what any probe concludes. - The controller latches decode_cap_kbps when two CONSECUTIVE backoffs carry decode-severe evidence (deep decode excursion or jump-to-live flush) at a similar pre-backoff rate, mirroring host_cap_kbps for the client decoder: a knee below the link ceiling was a permanent 30-60 s sawtooth costing a flush + dropped-frame burst per cycle (1440p120 HEVC field case, knee ~490 Mbps). One spurious flush never latches; the cap re-probes on the CAP_REPROBE_WINDOWS clock, so it lifts when the decoder recovers. Also rights the three stale "3 Gbps" probe-clamp comments (the host constant has been 10 Gbps since MAX_PROBE_KBPS moved).

enricobuehlerandClaude Fable 5	0d004c4680	fix(host/handshake): the 4:4:4 gate names the encoder backend, not the capturer ... capture_supports_444 was an encoder-backend fact (direct NVENC or PyroWave) logged under a capture-ish name — a field report burned real time hunting a capture problem because of it. The 'encode chroma' line now says ingest_chain_supports_444, a requested-but-declined session logs WHICH gate lost, and the console UI's Full chroma explainer names the real requirement.

enricobuehler	ea469162f9	fix(docs): three doc comments start a markdown list they never meant to ... Windows clippy on the v0.23.0 tag: `doc_lazy_continuation` in crates/pf-client-core/src/audio_wasapi.rs:37. The cause is one line break — `+ wire cost.` begins a line, so the markdown parser reads `+` as a bullet marker and the following line becomes a lazy continuation of that list item. Fixed by reflowing so the `+` is mid-line rather than by taking clippy's suggested indent: indenting would keep the accidental bullet in the rendered docs, which is the actual defect. Same treatment for the two siblings a sweep of every `///` line found, both invisible to the Linux gate for their own reasons: - gamestream/audio.rs:237 — `+ libopus;` at line start, on the cfg(not(linux/windows)) stub, so only a macOS clippy would ever see it. - mgmt/tests.rs:1653 — `404.` at line start IS an ordered-list marker (CommonMark: 1-9 digits + `.`), and it is behind cfg(test), so only an --all-targets run sees it. This is the [[Windows clippy sees what the Linux gate structurally cannot]] shape again: audio_wasapi.rs is cfg(windows), so no amount of Linux CI would have caught it. Verified: a scanner over every .rs doc comment in the tree now reports zero line-initial list markers with an unindented continuation; rustfmt clean (it does not reflow doc comments, so these edits are stable).	2026-08-01 01:30:45 +02:00

enricobuehlerandClaude Fable 5	f3a39df7b3	test(host/audio): prove a reopen recovered with a live uplink, not one frame ... `reopens_after_push_death` failed about one run in nine, and widening its timeout did not help — the earlier commit blamed the backoff and was wrong. The pump drops whatever queued while it was down: audio from before the device came back is stale, so a fresh instance drains the channel right after opening. The harness counts `opens` from the START of the open, so the moment the test sees the counter move, the pump has not reached that drain yet. The single frame it then sent landed inside the drain window and was discarded exactly as designed, leaving the test waiting for audio that was never going to arrive. So the test now keeps feeding, which is what a real uplink does and what the drain assumes. The sequence advances each time or the de-jitter reads the repeats as duplicates and drops them for a second, correct reason. Production behaviour is unchanged: this was the test asserting something the pump never promised. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-08-01 00:41:07 +02:00
enricobuehlerandClaude Opus 5	0985726415	fix(host,web): an empty update channel stops looking like a broken host ... A channel nobody has published to answers `manifest.json` with a 404, and the check reported that the same way it reports a dead registry or a bad signature: "Last check failed: feed returned HTTP 404". Every host on the stable channel shows it today, because the stable manifest only publishes when someone dispatches `announce` for a release tag — so the first thing an operator sees from the new Updates card is a red failure caused by nothing being wrong. The shared checker now distinguishes the two. `feed::fetch_manifest_blocking` returns a typed `FeedError` instead of a string, and only a 404 on the manifest ITSELF becomes `NotPublished` — a 404 on the detached signature still fails loudly, because that is the half-published pair the manifest-then-signature upload order can produce, and it must stay fail-closed. The host carries that through as `UpdateStatus.not_published`, mutually exclusive with `last_error`. It is benign only while no manifest has ever been seen for the channel: once a check has succeeded, the same 404 means the feed LOST a document it used to serve, which stays an error. The console then shows a plain sentence naming the channel instead of the failure banner, and "None published yet" rather than "Not checked yet". The Linux client makes the same distinction but deliberately NOT the same choice: `--check-update` keeps exiting 1 and keeps `error` set, because its consumer is a shell script and an empty channel is the absence of evidence that this build is current — not a confirmation that it is.

enricobuehlerandClaude Fable 5	10a1863cc7	test(host/audio): give the reopen tests longer than the backoff they wait for ... `wait_until` allowed 200 × 10 ms — exactly the 2 s `backoff_start` the reopen path spends before it can succeed. On a warm, idle machine it wins the race; on a cold binary or a loaded box it does not, and `reopens_after_push_death` failed 3 of ~5 cold runs while gating this branch. CI is always cold. Six seconds costs nothing when the test passes and only delays a genuine failure, so the budget now clears the backoff with room to spare.

Main moved through the same surfaces while the audio work was in flight, so three files needed hand-resolution: - clients/windows/src/app/settings.rs — main gave Windows its speaker and microphone endpoint pickers, the gap this branch could only report. Both keep their rows: the pickers, then Echo cancellation, and the microphone description keeps the sentence naming the mute chord. - crates/pf-console-ui/src/screens/settings.rs — both sides grew the couch row list. Main's seven new rows and Echo cancellation are all reachable in Gaming Mode; the count is 22 and the rationale comment names echo cancellation among the fields that would otherwise be unreachable there. - crates/pf-presenter/src/run.rs — both sides added a stats test at the same line.

enricobuehlerandClaude Fable 5	9f72a3b6ad	feat(host): HDR and 4:4:4 stop being mutually exclusive on Windows ... An HDR display cost you full chroma: the IDD-push capturer's only 10-bit output was P010, so a session that negotiated 4:4:4 on an HDR desktop was converted to 4:2:0 at capture time — *after* the Welcome had already told the client 4:4:4. The client believed it (nothing on the wire contradicts a Welcome), and the new chroma tag in the stats overlay is what finally made the discrepancy visible. Everything except the source was already in place, which is why this is small: the NVENC config layer has stamped `FREXT` + `chromaFormatIDC=3` + `pixelBitDepthMinus8=2` — HEVC Main 4:4:4 10 — with a unit test since the 4:4:4 work landed, `PixelFormat::Rgb10a2` already maps to `ABGR10` and already counts as a full-chroma input, and the desktop client learned the 10-bit 4:4:4 Vulkan pool format in 74863c96. The one missing piece was a capture format that keeps 10 bits AND full chroma. `HdrRgb10Converter` is that piece: one full-res pass from the FP16 scRGB desktop to packed `R10G10B10A2` in BT.2020 PQ, reusing the P010 shader's `scrgb_to_pq2020` verbatim so both HDR outputs share bit-identical colour math — it simply stops before the RGB→YUV matrix, the studio-range squeeze and the chroma decimation. NVENC then does the CSC to YUV 4:4:4 itself under FREXT, exactly as the SDR BGRA passthrough has always done at 8 bits. No swizzle is involved and that is worth stating, because it looks like it should be: NVENC names packed formats from the MSB down, so its `ABGR10` (A2B10G10R10) puts R in the low 10 bits — bit-identical to DXGI `R10G10B10A2_UNORM`. It is the same relationship the proven SDR pair relies on between DXGI `B8G8R8A8` and NVENC's `ARGB`. The honesty gap closes as a consequence: `capturer_supports_444` no longer has a depth it cannot serve, so the chroma resolved before the Welcome is the chroma the wire carries. AV1 is deliberately untouched — Range Extensions are HEVC-only and no consumer encoder does AV1 4:4:4. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-31 23:06:44 +02:00
enricobuehlerandClaude Fable 5	79856d2c50	fix(host/audio): a VoiceMeeter box can no longer loop the mic into the stream ... wiring_plan could hand the mic Voicemeeter Input and the loopback Voicemeeter Aux Input — two strips of the same internal mixer, i.e. a digital feedback loop with no acoustic path to break it, because leftover() never asked virtualish() and the exclusion list only knew "cable" and the Steam Speakers. Now every VoiceMeeter or generically "virtual" render is excluded from loopback, and the last-resort tier refuses anything virtual: a box with only mixer endpoints gets loopback=None, honest like the cable-only case.

enricobuehlerandClaude Fable 5	efac33fd33	feat(host/audio): the virtual mic buffers for the client it has, not the worst one ever ... The mic pump grows a real de-jitter (audio/mic_jitter.rs): a two-frame reorder window in front of the decoder, libopus concealment on sequence gaps (up to 5 frames — a lost datagram no longer drains the ring into a silence + re-prime crackle), and an adaptive target depth measured from inter-arrival jitter, clamped to 10–60 ms. Both backend rings now prime at one consumer quantum + that target: the old bursty Mac client still measures ~42 ms and lands where the fixed 48 ms prime protected it, a modern 10 ms-cadence client settles at ~25–35 ms, and a 2048-frame recorder on Linux stops buying 128 ms of latency from the 3-quanta clamp. Depth stuck above target sheds near-silent frames a few ms per 100 ms — never speech, never a hard clear. PUNKTFUNK_MIC_LEGACY_BUFFER=1 (documented) is the one-release escape hatch back to the fixed constants, and a "mic uplink health" line every 30 s (depth/target, cadence, gaps, conceals, reorders, drops, re-primes) finally says which side of the link a bad mic lives on.

enricobuehlerandClaude Fable 5	6286f91f89	feat(host/audio): the mic uplink keeps its sequence, and a backlog heals itself ... The 0xCB datagrams always carried a seq + pts, and the ingest threw both away one line after decoding them — the pump saw an anonymous byte pile. Frames now travel as MicFrame {seq, pts_ns, opus} so the de-jitter that follows can reorder, conceal and measure. The shared queue also stops being a latency reservoir: cap 64 → 12, and a pump that wakes to a backlog deeper than 6 frames jumps to the newest 4 instead of replaying the pile — before this, a scheduling stall could park up to 1.28 s of standing mic delay that only a >600 ms silence gap ever flushed.

enricobuehlerandClaude Fable 5	5926306a4c	feat(windows): the web console becomes a supervised child of the host service ... Three silent console outages in one week (0x1 / 0xFFFFFFFF / 0x41306), each a different proximate cause of the same structural defect: the console's lifecycle was owned by Task Scheduler — one best-effort start per boot/logon/install, no retry on a plain non-zero exit, no watchdog — while the product already shipped a real supervisor. The service now supervises the console as a second child slot: plain session-0 spawn (suspended → own no-breakaway kill-on-close job → resume), started only once the host has written mgmt-token + cert.pem + key.pem (the cert race dies by construction), secrets read from their files at every respawn, bun's stdout finally captured in logs\web.log, doubling backoff 0.5s→60s that never gives up. Session switches never touch it; a service stop takes it down via the job. The PunktfunkWeb task is retired: web setup slims to password + legacy task delete + firewall, the 127-line web-run.cmd batch supervisor is deleted, an [InstallDelete] entry reaps the stale copy, and service install now sets SCM crash-recovery actions (restart 1s/5s/60s) since the console rides on the service process. StopBunRuntimes stays for the scripting runner + the one migrating upgrade.

enricobuehlerandClaude Opus 5	020306b5ac	fix(packaging,host): a fresh Linux install can start, and the comments stop lying ... Fallout from the documentation sweep: verifying doc claims against the code turned up defects in the code and the shipped templates. Mostly comments that describe behaviour we no longer have — which is how the docs went wrong in the first place, since someone reads the comment and writes the page. The one that mattered: a fresh deb/RPM/Arch install could not start the host at all. The unit's `EnvironmentFile=` had no `-`, making host.env mandatory, and no package creates it — all three ship only the templates under /usr/share and the postinst merely prints the copy command. So `systemctl --user enable --now punktfunk-host` died on "Failed to load environment files". Every field in HostConfig::from_env resolves through unwrap_or/filter/None, so absent means all defaults, exactly like a hand-run `serve`; the Nix module already wrote it as `-${environmentFile}`. The Deck installer's own generated unit gets the same prefix for the case where an operator later removes the file. Shipped templates: PUNKTFUNK_SECURE_DDA is read by nothing (DDA/WGC are gone; IDD-push is the sole Windows capture path and the secure desktop is unconditional), so it stops being written into a fresh host.env; PUNKTFUNK_INPUT_BACKEND offered a `uinput` value that does not exist and omitted `kwin`, which is what a KDE session actually resolves to; PUNKTFUNK_RENDER_ADAPTER no longer claims to pick a "Desktop-Duplication" GPU. Comments corrected rather than deleted, since each explains a real why: PUNKTFUNK_10BIT is default-on with explicit-off grammar, not an operator opt-in; GNOME reaches EIS through Mutter's direct RemoteDesktop API, so it needs no portal approval and is headless-capable; and the host does not run in session 0 — the service is the session-0 supervisor and the host runs as SYSTEM in the interactive console session, which is why game_term has to bind the input desktop at all. packaging/bazzite/update-punktfunk.sh is now installed to /usr/share/punktfunk/, so the command the docs promised exists.

enricobuehlerandClaude Opus 5	5520167958	feat(clients): the OS marks tell gaming distros apart, and Windows looks current ... Three things were wrong with the host-card OS icons. The Windows mark was Font Awesome 5's, which is still the Windows 8/10 flag with the perspective skew — dated next to the flat four-pane mark Microsoft has shipped since Windows 11. No icon set has the current one (Simple Icons carries no windows/microsoft slug at all), so it is drawn here: four equal squares at the authentic 11.377 + 1.246 proportion. The Decky plugin was pulling FaWindows straight from react-icons, so it now inlines the masters like the web console does, or it would have kept the old flag regardless. Bazzite, CachyOS and Nobara collapsed onto their family's mark. The host already advertises the full chain, so this is purely missing art: all three now ship a leaf mark, because "a Bazzite box" and "a Fedora box" are different machines to the person reading the card. CachyOS and Nobara come from Simple Icons; Bazzite has no icon anywhere, so its "b" is lifted out of the project's own badge (Apache-2.0, attributed). On Android every non-square mark was stretched. A VectorPainter maps the viewport onto the ImageVector's default size with independent x and y scales, so declaring a 448x512 Tux as 24x24 dp squashed it — silently, no crash, no warning. The longest viewport edge now sets the 24 dp box and the other follows the ratio, which is what Icon()'s ContentScale.Fit expects. A unit test pins the invariant; every other client was already correct. Also: scripts/gen-os-icons.sh replaces the undocumented hand-run pipeline that turns a master into the GTK symbolic SVG, the Windows PNG and the Apple template PDF. It reproduces the committed artifacts byte-identically. Verified: web and Decky typecheck, Decky bundles, Android compiles and its tests pass, PunktfunkKit builds, osinfo's tests pass. Not verified on glass, and the GTK/Windows client crates do not build on macOS. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-07-31 14:17:02 +02:00
enricobuehlerandClaude Fable 5	f4f83202cb	feat(core/client): an AU's prefix reaches the decoder while its tail is on the wire ... Delivery used to be all-or-nothing: the decoder saw byte 0 only after the last packet of the AU landed, so the whole transmit time sat in front of decode. With the slice-streamed wire (previous commit) blocks now arrive addressable, and a client can opt in (connect's new frame_parts) to receive each AU's newly-contiguous prefix as Frame::part pieces - offset tiling, first/last marked, the completing push carrying only the suffix. A PARTIAL_FRAME-capable decoder then chews slices concurrently with the remaining network transfer. The reassembler walks a per-frame cursor over successfully-completed blocks (failed FEC reconstructs don't advance it), coalesces blocks that finished out of order into one part, keeps probe filler whole, and stops short of the final block so the zero-padded tail still trims at completion. Whole-frame consumers see byte-identical behavior - parts never flow without the opt-in, and never on PyroWave (its newest-wins draining assumes whole AUs). Per-AU accounting keeps its units: OWD/ABR feeds, the inter-arrival series and the clock-based jump-to-live detector only count completing deliveries, and FrameChannel::depth() counts AUs so a part-rich queue can't trip jump-to-live at a fraction of the real backlog. The consumer contract (gap or orphan part = AU lost: abandon, flush, resync on the next first) is documented on FramePart; the C ABI keeps parts off until PunktfunkFrame can express them.

enricobuehlerandClaude Fable 5	440cb8d1ec	feat(core/wire): streamed AUs cut blocks at slice boundaries, not at 5.5 MB ... The streamed-AU path only ever flushed a block when a full FEC block's worth of bytes accumulated - at real bitrates a frame finished encoding before that, so every AU degenerated to one tail-heavy send and the overlap the sentinel wire was built for never happened. Now a slice boundary flushes every whole shard (floored at MIN_STREAM_BLOCK_SHARDS so per-block parity stays economical), which means blocks are variable-size and can no longer be addressed by the uniform block_index * K_max formula. USER_FLAG_SLICE_STREAM marks such frames on every packet: sentinel blocks reuse frame_bytes as their shard-aligned base offset, the final block's base derives from the totals, and the receiver pins/validates positionally (sentinels must sit strictly below the final block's base; a mixed-flag or out-of-range header is dropped before it can place a byte). The AU's own flag bit gates the wire shape, and the host sets it only toward clients advertising STREAMED_AU + MULTI_SLICE, so shipped receivers keep seeing the byte-identical legacy sentinel (PUNKTFUNK_SLICE_STREAM=0 pins legacy for A/B). Both sides bound the per-frame block count by the same floored formula, and the flush loop cuts as many blocks as a chunk completes - a slice bigger than one FEC block can't leave an oversized final block behind.

enricobuehlerandClaude Opus 5	78926be4ac	fix(store): a plugin install lands in the plugins dir, not the nearest package.json above it ... Installing any plugin from the console failed on a user's Fedora 44 host with plugin store job failed: @punktfunk/plugin-virtualhere is not present after install while the same version installed fine on every box we tried. The difference turned out to be a file in his home directory. `bun add` does not install into its working directory. It walks UP to the nearest ancestor `package.json` and installs into that tree. A fresh plugins dir has no `package.json` — the store and the runner only write `bunfig.toml` — so any stray one above it captures the install: the packages land in `~/node_modules`, the dependency is written to `~/package.json`, bun prints "installed …" and exits 0, and the plugins dir stays empty. The plugins-dir `bunfig.toml` is not read in that case either, so the outcome splits on whether `@punktfunk` resolves in the hijacked tree: with no scope mapping there it 404s against npmjs and exits 1 ("the plugin runner exited with status 1"); with one, it succeeds into the wrong tree and the job dies on the presence check instead. Only the second shape looks like a broken store, which is why this took a reproduction to find. Seed the plugins dir with a `package.json` so it owns bun's install root. Three call sites rather than one: the store job, the `plugins add` CLI, and the SDK's `ensurePluginsDir`. The runner ships as its own package and can predate the host binary, so the host cannot delegate this — the same reason `ensure_bunfig_scope` writes the registry mapping on this side rather than passing a runner flag. Seeding only ever touches a tree with no `node_modules`. A dir with packages and no `package.json` is the hand-assembled/older layout that `installed_packages` deliberately falls back to the naming convention for, and dropping an empty `dependencies` on it reports every plugin the operator runs as uninstalled — already pinned by `an_emptied_dependency_list_means_nothing_is_installed`. The residual failure stops dead-ending: if the presence check fails anyway, the error names the capturing ancestor and what to do about it. Reproduced and fixed on glass (Nobara 44 VM, host + runner 0.22.3): with a stray ~/package.json the store reproduces the field report byte for byte — same 150 ms, same phase sequence, same message — and with the plugins dir seeded the same install lands correctly with nothing leaking into the home dir.

enricobuehlerandClaude Fable 5	759aac255b	feat(phase-lock): controller v3 — grid-locked submits, arrival sensing, antipode damping ... Midday on-glass falsified v2's remaining assumptions: a per-frame additive hold SATURATES the arrival-slaved loop once hold + work >= interval — submits free-run at their own cadence and the commanded phase dissolves (measured: +-2 ms hold steps, zero client response) — and the latch statistic hovers at the target's ANTIPODE, where shortest-way errors sign-flip on noise (the 0<->2<->4 ms offset chatter). v3, one change per falsified assumption: - ACTUATOR: submits lock to an absolute grid (epoch + k x period + offset); the controller walks only the offset. A periodic grid cannot free-run — occupancy is one frame per period whatever the offset — so phase actuation is linear BY CONSTRUCTION. Disengaged = no grid sleeps = zero cost; every failure path DISENGAGES (never parks: v2's e2e-tax lesson). - SENSOR: the client reports the circular mean + coherence of the ARRIVAL lead (per-AU reassembly stamps vs the panel latch grid) — the phase the host actually controls; latch measured downstream of the decoder pipeline, which absorbed the actuation. pf.phase logs "arrival lead circ= coh=". - ANTIPODE DAMPING: errors within 1 ms of +-period/2 take half-steps until they commit to a side. Harness rewritten around plants glass validated: a GRID plant (linear by construction), the DECOUPLED plant (v2's saturation — must disengage, not orbit or park), an antipode start (must converge within one period of travel), incoherence (never engages), a regime change (re-engages after backoff), and the actuator's own periodicity/offset-linearity. Also fixes the harness's SIM_TARGET (a mis-derived max asserted 3.5 ms where the controller's actual target is 2.5 — the controller was right, the ruler was wrong; the Python cross-check inherited the same constant, a lesson in replicating the CODE, not the author's belief about it).

The stream.rs harness models the plant — latch = (base − hold + noise) mod P, deterministic LCG noise — and drives PhaseController::adjust through five regimes: - tight jitter locks into the deadband within ~5 adjusts and stops moving; - a wrap-side start takes the SHORTEST way (travel < P/2 asserted); - an incoherent phase never steps (zero hold, ever); - a v1 pinned-median report trips the travel budget and DECAYS TO ZERO — the 2026-07-31 orbit and the parked-hold e2e tax, both as asserts; - a post-decay regime tightening re-locks.

enricobuehlerandClaude Fable 5	1d31e4c565	feat(phase-lock): controller v2 — circular phase, coherence gate, decay-to-zero ... Round-1 on-glass falsified two v1 assumptions in one morning (NP3 ↔ .173): - A median lead is immovable under period-spanning jitter (uniform mod P), so v1 orbited the period at 2 ms/s forever — and the dead-signal freeze hotfix never armed, because ±1.5 ms of window sampling noise kept resetting its 'error responded' check. Thresholds can't referee noise. - A HELD hold is not free: it delays sampling after the capture stamp, taxing e2e by up to a period (user-measured: ~+4 ms during the orbit). The correct failure response is DECAY TO ZERO, never freeze-in-place. v2, all three layers: - Wire: PhaseReport grows a length-discriminated coherence tail (27-byte form; the u16::MAX sentinel encodes as the byte-identical 25-byte v1 — strict-prefix discipline, both forms pinned by tests). - Client: the reporter sends the CIRCULAR vector-mean latch phase mod the panel period + its coherence (‰); pf.present logs circ=/coh=. - Host: steps only while coherent (floor 300‰; a v1 report bypasses the gate), along the signed SHORTEST way around the period, under a cumulative 1.25-period travel budget that is noise-immune by construction (it integrates applied steps, not reported errors); incoherence or budget exhaustion decays the hold to zero and re-arms once flat.

enricobuehlerandClaude Fable 5	74ca42568a	fix(host/phase-lock): a dead error signal freezes the hold instead of orbiting the period ... First on-glass closed-loop run (NP3 ↔ .173, canary 0.23.10498) proved the transport and both endpoints work — and exposed the controller chasing a statistic that cannot respond: under period-spanning arrival jitter the client's latch DISTRIBUTION is ~uniform mod the refresh, so shifting its mean (the hold — provably reaching the client: the paced-drop bursts locked to each wrap) cannot move its MEDIAN. The controller stepped +2 ms/s in one direction forever, wrapping the period every ~4 s, and every wrap coalesced ~30 frames at the client — a periodic hiccup that must not ship. The controller now remembers its last error: three consecutive steps that fail to move it ≥1.5 ms freeze the hold (kept, not zeroed) and log; a later report whose error moved re-arms stepping — a tight-jitter regime still locks exactly as designed. Controller v2 (a circular phase statistic with a coherence gate, per the design doc's follow-ups) replaces the median outright; this freeze stays as its safety net.

3 people	f6cfe382fd	refactor(update): one signed-manifest checker, shared by the host and the client ... The host has known how to answer "is a newer build available for this box's channel?" since the update-from-web-console work. The Linux client is about to need the same answer from the same signed document, and a trust rule that lives in two places is a trust rule that will drift. So the parts where being wrong is a security bug now exist exactly once, in the new `pf-update-check`: Ed25519 verification against pinned keys, the manifest schema and its fail-closed validation, the post-redirect fetch, the version comparison that has to reconcile four different canary spellings, and the install-kind ladder — the last parameterised by which product is asking, since the delivery channels are the same ones but the markers are not. The pinned key list moves with them. Two lists could have disagreed about who may announce a release, and the one that drifted is the one nobody would have noticed; `publish-update-manifest.sh` follows to the new path, and a MISSING keys file there is now fatal rather than a warning that silently skips the cross-check the step exists to perform. Host call sites are unchanged throughout: `store::index` and `update::manifest` re-export from the shared crate under their old names, and `update::detect` keeps its cached `detect()` and the host's command hints. Verified with clippy -D warnings on Linux and on Windows (nvenc,amf-qsv,qsv), 340 host tests green. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-07-31 09:41:26 +02:00
enricobuehlerandClaude Fable 5	fa822744ff	feat(core/host/android): phase-locked capture — frames arrive on the client's latch schedule ... The host's capture tick and a client's panel vsync are independent ~120 Hz oscillators; their drifting phase sweeps every frame's wait-for-latch across a full refresh period (measured on-glass: latch p50 oscillating 5.4-8.9 ms with a fixed margin) — the beat is the residual judder and the fat p95, and no client can fix it alone. Design: punktfunk-planning design/phase-locked-capture.md. Protocol (punktfunk-core): - PhaseReport (control 0x32, next to the clock family): the client's next display latch ALREADY CONVERTED to host clock (the skew offset lives only client-side), panel period, uncertainty, and the measured median arrival-lead — the controller's error signal. ~1 Hz, latest-wins. CLIENT_CAP_PHASE_LOCK advertises it; CtrlRequest::Phase + report_phase() + the C ABI mirror carry it. - The 0xCF host-timing tail grows a phase ACK (applied_phase_ns, 29-byte form) under the same strict-prefix append discipline — old readers parse the shorter forms; degradation pinned by tests. Host engine (arrival-slaved loop — no backend can move the source vsync, per the tick-ownership audit in the design doc): - PhaseCtl bridges control task → encode loop (the fec_target pattern, multi-field). PhaseController walks a per-frame HOLD before submit toward the client's reported lead hitting target = max(2.5 ms, uncertainty+1ms): 1 Hz adjust, 2 ms max step, 300 µs deadband, period-wrapping (the newest-wins capture slot makes a wrapped hold sample fresher content, not staler). A loop local, so every mid-stream rebuild keeps the lock; a new session re-acquires. PUNKTFUNK_PHASE_LOCK=0 disarms. Android reporter: the presenter's 1 Hz pf.present flush returns the window's measured latch p50; the async loop converts the vsync clock's next timeline monotonic→realtime→host and reports. Inert toward old hosts. Gates: docker amd64 clippy --all-targets -D warnings (host+core, nvenc) clean; core suite incl. the new wire tests; cargo ndk arm64 check/clippy clean.

enricobuehlerandClaude Fable 5	f87c1e6cec	fix(encode): gate multi-slice frames on the client's decoder — the 0.17.0 Chromecast crash ... Field report: since 0.17.0 a stream to a Chromecast with Google TV 4K freezes on the first frame and ~80% of the time crashes + reboots the DEVICE — with both the Punktfunk app and Moonlight, while an Xbox Series S is fine. Root cause: LN1 Phase 3 (67b79810) defaulted Linux direct-NVENC to 4 slices per frame for EVERY session. Amlogic HEVC decoders wedge on multi-slice AUs — exactly why moonlight-android requests slicesPerFrame=1 for every hardware decoder (4 only for software slice-threading) — and our RTSP parser never read the request. The Phase-3 commit recorded the untested leg ("a live Moonlight re-test joins the standing owed Moonlight item"); this report is that re-test. The slicing ceiling now belongs to the CLIENT, threaded as open_video's new max_slices from both planes: - GameStream: parse x-nv-video[0].videoEncoderSlicesPerFrame into StreamConfig and honor it; absent/out-of-range (pre-auth input) => 1. - punktfunk/1: new Hello cap VIDEO_CAP_MULTI_SLICE (0x80 — the byte's LAST free bit; the next cap needs a second byte + ABI bump). SessionPlan.max_slices = 32 with the bit, 1 without, applied to every encoder the plan opens so rebuilds can't change the wire shape. The desktop session client advertises it (FFmpeg/D3D11VA/Vulkan decode stacks are fine); Android/Apple stay off until they can decide per-decoder like Moonlight does — the cap is embedder-set decoder truth, never OR'd in by the shared pump. - Linux direct-NVENC clamps its Phase-3 default to the ceiling (resolve_slices(codec, 4.min(max_slices))) and logs slices/max_slices in the caps-probe line; PUNKTFUNK_NVENC_SLICES stays the explicit operator override in both directions. Windows keeps its single-slice default untouched. Also repairs the nvenc_cuda #[ignore] hardware tests: d2c46eaf added open()'s cursor_blend param without updating them, invisible because CI never compiles tests with the nvenc feature. Verified on .21 (RTX 5070 Ti): pf-encode + host check/clippy clean with nvenc; host unit suite 263/0; rtsp announce tests 7/7 incl. the new slicesPerFrame coverage; on-hardware smokes — default e2e still 4 chunks/frame, NEW single-slice client-ceiling test clamps + disarms chunked poll with no env involved, env escape unchanged. rustfmt clean. Windows leg (prepare_display param) is CI-only. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-30 22:23:42 +02:00
enricobuehlerandClaude Opus 5	d9912aa795	fix(windows/update): an update puts the status tray back instead of killing it for good ... Every update started from the web console killed the tray permanently. Three pieces had to line up, and they did: the installer's StopTrays force-kills every punktfunk-tray.exe (it is one of the files being replaced), its relaunch is a [Run] entry flagged skipifsilent, and the in-console updater spawns the installer with /VERYSILENT. So the tray died on every such update and waited for the next sign-in, because the Run value is a logon trigger. Confirmed on a box whose tray was absent while its Run key, its exe and a session signed in hours before the update were all present. The installer cannot fix this itself. Spawned from the SYSTEM host service, its `runasoriginaluser` resolves to SYSTEM — so relaunching there would place a SYSTEM-owned tray in the user's session, where it would hold the per-session Local\PunktfunkTray mutex and block the real tray at the next sign-in. Strictly worse than the bug. The host does it instead, because only the host has the right token. IntentRecord gains tray_was_running, captured before the installer is spawned (reusing the conflicting-host scan's process snapshot rather than opening a second one), and boot reconciliation reads it off the intent before reconcile consumes it and relaunches through tray::start(). Restored on both terminal outcomes — a rolled-back install killed the tray just as dead as a successful one — but never while an apply is still in flight, where the installer may only kill it again. The field is serde(default), so an intent written by an older host reads as false and behaves exactly as before; covered by a test.

enricobuehlerandClaude Opus 5	c77823d800	feat(windows/tray): punktfunk-host tray start|stop|status, so a dead tray is one command away ... The status tray is a per-user, per-session GUI process with no recovery path of its own: the HKLM Run value only fires at sign-in, and nothing in the product ever restarts one. Anything that kills a tray — an upgrade's StopTrays, a crash — therefore left the operator without an icon until they signed out and back in, with no way to ask for it back. windows/tray.rs becomes the one place that knows tray lifecycle (find, start, stop, is-running), so the CLI and post-update reconciliation share an implementation rather than growing two. start() cannot simply spawn the exe, because the launch crosses a privilege boundary in one direction only: - from the host service (SYSTEM) the tray must land in the active console session under the LOGGED-IN USER's token, which is WTSQueryUserToken + CreateProcessAsUserW and needs SE_TCB — SYSTEM-only; - from a shell already in the console session that call fails (an administrator does not hold SE_TCB either) and a plain spawn is both sufficient and right. Trying the privileged path and falling back discriminates the two without inspecting a token, and adds no unsafe to the crate. But a plain fallback from ssh/RDP would put a tray in a session nobody can see and report success, so on failure it consults console_session_mismatch() and refuses with an explanation instead. stop() is graceful first (--quit lets the tray remove its own icon via NIM_DELETE, as the uninstaller does), then forces any instance in another session. Verified on Windows: launched from a SYSTEM scheduled task the tray comes up in the console session owned by the interactive user, not SYSTEM; from an ssh session (0 -> console 2) it refuses; a second start is a no-op; stop is graceful and idempotent.

enricobuehlerandClaude Opus 5	3bb30cb2f6	fix(windows/web-console): a bun exit no longer parks the console until the next sign-in ... The PunktfunkWeb task registers RestartCount=10/PT1M, but Task Scheduler honours restart-on-failure only when the action crashes or fails to start — never for a plain non-zero exit. So any bun exit left the console down until the next boot or interactive logon, with the host still streaming perfectly next to it. Seen on glass on a 0.22.3 upgrade: `web setup` started the task one second after the new service came up, bun exited at once (Last Run Result 0xFFFFFFFF), and the console sat dead for hours while its box served clients — which reads to an operator as "the host is gone". web-run.cmd now supervises bun instead of exiting with it: restart on any exit, indefinitely for a console that served a while and then died, but give up after 10 CONSECUTIVE fast exits so a genuinely broken install still surfaces as a failed task. Any run lasting >= 60s resets that counter. It exits 0 rather than respawning when the payload disappears, so an uninstall does not make it spin. Uptime is measured with an unambiguous clock rather than parsed out of %TIME%, which is locale-formatted (12-hour locales append " PM", many others use ',' as the decimal separator) — the box this was found on prints 18:36:28,39. stop_web_console() polls until :47992 is really free instead of sleeping a blind second: both `schtasks /end` and `taskkill /F` are asynchronous, and web_setup starts the new task immediately afterwards, where bun cannot bind a port the corpse still holds. It re-ends the TASK halfway through, not just the listener — with the launcher now supervising, killing bun alone would be undone by its own restart loop. The systemd unit had the same shape of hole: Restart=on-failure leaves a console that exited 0 down. Now Restart=always, which an explicit `systemctl stop` still overrides.

enricobuehlerandClaude Fable 5	3b1485e2a1	fix(plugins/windows): the runner can read its own bundle, so it actually starts ... Enabling the plugin runner did everything right and then nothing happened. The task went Ready with LastTaskResult 1 within a second of every start, and the console kept showing it enabled-but-not-running with nothing to explain why. Task Scheduler discards the action's output, so the reason never surfaced anywhere: error: EPERM reading "C:\Program Files\punktfunk\scripting\runner-cli.js" This file already knows why. RUNNER_UNIT_DIRS carries the note that bun opens the files it loads asking for FILE_WRITE_ATTRIBUTES on top of read, so a plain (RX) grant makes them die with EPERM — found on glass when the plugin and script directories were fixed. The runner's own entry script was missed. It lives in {app}\scripting, which carries only Users:(RX), and LocalService reaches that through Authenticated Users, so bun could never open the one file it was started to run. The runner has not been able to start since it moved off SYSTEM, which is a principal that has full control everywhere and so never met this. So {app}\scripting now gets the same (OI)(CI)(RX,WA) the unit dirs get, at enable, revoked at disable like every other grant here. WA moves timestamps and the read-only bit and cannot touch content, so the three-way split the module maintains still holds: code read-only, secrets read-only, only plugin-state writable. A plugin still cannot rewrite the runner. Measured on glass on .173, same box, same task, only the ACE differing: without it Ready/lastResult=1 and no runner process; with it Running, a live runner, and GET /store/runtime answering running:true — which is exactly what the console reads. Also checked what bun does with the access: nothing. It opens the entry for write and never writes, and the directory is byte-identical afterwards. Windows-only code, so it is rustfmt-clean and type-reviewed but NOT compile-verified here — the Windows CI job is the gate.

enricobuehlerandClaude Fable 5	4a540bddc8	feat(host/deck): one-click source rebuild — the update.sh run as a transient user unit ... The U3.1 leg of planning:host-update-from-web-console.md. The Deck's on-device install gets the Update-now button with no opt-in (user-owned, no root): update.sh --pull runs under systemd-run --user so the script's own restart of punktfunk-host can't kill it mid-build (a child in our cgroup would die with us). Outcome without version equality — which a source rebuild can't promise: a failed build leaves the host alive to report it (unit watched to failure, log attached); a successful one restarts us, and the new source_build intent flag makes intent-present-at-boot itself the success signal (the script only restarts the host after a successful install). The console stops treating a live long build as a timeout. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-30 16:28:40 +02:00

The U3.2 leg of planning:host-update-from-web-console.md. The service worker loop — the one piece that survives an upgrade — detects a fresh update-intent whose target version is the crash-looping child (≥3 rapid restarts, intent <30 min), then exactly once: picks the newest cached non-target installer, requires a valid Authenticode signature, writes a rolled-back result record for the console, deletes the intent, and spawns the installer silently. No cached installer or a failing signature degrade to today's backoff loop with a loud log — never a brick, never an installer loop.

enricobuehlerandClaude Fable 5	06a249e49f	feat(host/linux): opt-in one-click updates — the pf-update root helper, group-scoped polkit grant, per-PM legs ... The U2 leg of planning:host-update-from-web-console.md. A new dep-free root helper (crates/pf-update) runs the distro package manager against the INSTALLED punktfunk packages — apt (index refresh scoped to our list when present), dnf, rpm-ostree (single-transaction re-resolve, reported staged), sysext (the proven signed-feed updater), pacman only behind the explicit PACMAN_FULL_SYSUPGRADE opt-in — then the run-the-binary gate, then a root-written result record. Zero attacker-influenceable parameters end to end: fixed ExecStart oneshot (punktfunk-update.service), polkit rule scoped to that one unit's start verb for the shipped-EMPTY punktfunk-update group (joining it is the auditable opt-in; every postinst creates it, none populate it). The host starts the unit, interprets the record (staged / nothing-newer-yet / changed), and crosses its own restart on the same intent/reconcile machinery as the Windows leg. Status now reports staged results and the opt-in hint. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-30 15:55:27 +02:00

The U1 leg of planning:host-update-from-web-console.md. The apply request carries no version/url/channel (the zero-parameter invariant): the host installs exactly what its Ed25519-verified manifest announced. Pipeline: staged download (resume + disk preflight) → manifest sha256 → Authenticode (valid signature, untrusted root tolerated while the cert is self-signed; leaf sha256 pinned via the signed manifest, extracted from the SAME WinVerifyTrust state) → intent record → detached CREATE_BREAKAWAY_FROM_JOB spawn of the winget-blessed silent flags. The installer kills this process by design; boot-time reconciliation reports the outcome (update.applied event / a durable failure with the installer log path) across the restart. Session guard (force to override), PUNKTFUNK_UPDATE_APPLY=0 kill switch, single-flight via job + fresh-intent detection.
