feat(vdisplay/mutter): optional virtual-output-as-primary for monitored GNOME hosts
PUNKTFUNK_MUTTER_VIRTUAL_PRIMARY=1: after RecordVirtual, promote the per-session virtual output to the primary monitor (physical kept on, secondary) via org.gnome.Mutter.DisplayConfig.ApplyMonitorsConfig, restoring on teardown. Without it, a GNOME host that also has a physical monitor attached keeps the physical primary, so the virtual output is an empty extended desktop — the client streams only the wallpaper. (The backend was validated on headless GNOME, where the virtual output is the only display.) Best-effort + opt-in: default behavior is unchanged; any DisplayConfig failure just logs and streaming continues. method=temporary, so nothing is written to monitors.xml and Mutter auto-reverts the layout when the virtual output is torn down.

feat(latency): wall-clock skew handshake for cross-machine latency measurement
ci / rust (push) Has been cancelled
ClockProbe/ClockEcho on the QUIC control stream — 8 NTP-style rounds right after Start; the min-RTT sample gives the host-client clock offset (clock_offset_ns estimator in punktfunk-core). The client adds the offset to its receive instant before differencing against the AU pts_ns, so the capture->reassembled latency percentiles are valid across machines (skew_corrected=true), not just same-host. Back-compat: an old host that doesn't answer the probe times out and the client falls back to a shared-clock assumption (skew_corrected=false). Host adds one ClockProbe dispatch arm in the control task; the client runs clock_sync after Start, before the --remode/--speed-test tasks take the stream. Validated cross-LAN (GNOME box -> dev box): offset ~ -1.57 ms (reproducible), rtt ~140 us, p50 1.30 ms skew-corrected capture->reassembled — the offset is exactly the systematic error the handshake removes. Unit tests for the message codecs and the min-RTT offset estimator. Roadmap §12: skew handshake done; remaining for true glass-to-glass is the Apple client present-stamp (decode->present) plus the host render->capture term.

feat(discovery): native-protocol LAN auto-discovery over mDNS
ci / rust (push) Has been cancelled
Both the unified host (serve --native) and standalone m3-host now advertise the native punktfunk/1 service over mDNS (_punktfunk._udp) — the analogue of the GameStream _nvstream._tcp advert. TXT records carry proto, the host cert fingerprint (fp, the value clients pin), the pairing requirement (pair=required|optional), and the host id. New crate::discovery module, wired into m3::serve so both host entry points get it; best-effort, never blocks streaming (--connect always works). Client gains `punktfunk-client-rs --discover [SECS]`: browses the LAN and prints each host (name, addr:port, pairing, fingerprint), then exits. Apple clients browse the same service natively via NWBrowser (service type + TXT keys are the contract). Validated cross-LAN: the dev box discovered the GNOME-box appliance (pair=required) and a standalone synthetic host (pair=optional); fingerprint and pairing state correct in both. Also refresh the now-stale sendmmsg caveat in the bitrate doc (batched/paced send landed + validated to 1 Gbps) and mark the encode|send thread split done in §12.

perf(latency): encode|send thread split on the native path
ci / rust (push) Has been cancelled
Bigger-bet #1 from the latency plan. virtual_stream ran capture+encode+seal+ paced-send on ONE thread, so frame N+1's capture/encode couldn't start until frame N's entire paced tail had left the wire — the pacing budget (~0.9×interval) was serialized in front of the next encode. Port GameStream's spawn_sender model to the native path: - A dedicated send thread (`send_loop`) owns the WHOLE Session (so no socket clone or shared/Arc stats needed — `seal_frame` mutates the nonce, `send_sealed` + the probe bursts all live there) and does FEC+seal + microburst-paced send. - The encode thread captures+encodes + handles reconfig and hands each AU over a bounded sync_channel(3) as a FrameMsg (data, capture_ns, flags, deadline, encode_us). It BLOCKS on backpressure if the send falls behind — frames slow down rather than a dropped frame freezing the infinite-GOP stream (we don't drop). Clean shutdown: drop the channel → send thread drains/exits → join. - Probes (run_probe_burst) move to the send thread since they need the Session; a burst naturally pauses video (the encode thread blocks on the full channel). - Per-frame encode_us/pace_us histogram moved to the send thread (carries encode_us in the FrameMsg) and now reflects the overlap. Removes the encode↔paced-tail serialization (~2-8 ms @60-120 fps), independent of the pacing policy, no quality cost. Substrate for the future NVENC slice wrapper. Verified live on this box (appliance restarted onto it): a client streamed the KWin desktop (1.49 MB H.265, clean, no panic) and a 200 Mbps speed-test probe completed through the send thread (0 drops). Build + clippy + fmt green. Real-NIC sustained soak (reconfig under load, line-rate, mode switches) pending the Ubuntu third host.

fix(housekeeping): unaligned read UB + recv-drop parity; dedup mmsghdr; doc fixes
ci / rust (push) Has been cancelled
From a bug-hunt + unsafe-audit pass (4 reviewers + adversarial verify). It confirmed ZERO real bugs in the recent batched/paced data-plane work — these are the surfaced cleanups + one genuine soundness fix: - SOUNDNESS (reduce unsafe): inject/gamepad.rs::pump_ff did `ptr::read` of an InputEventRaw (align 8, holds a timeval) out of a 1-aligned [u8; N] buffer — UB per the reference (x86_64 tolerates it, but it can miscompile under LTO). Use ptr::read_unaligned + a SAFETY note. Zero behavior change. - recv parity: recv_batch (recvmmsg) didn't drop an oversized/truncated datagram the way scalar recv does — poll_frame now skips a message whose len fills the buffer (> MAX_DATAGRAM_BYTES), matching recv's `n >= RECV_BUF` drop. (AEAD already rejected these on encrypted sessions; this restores the documented invariant on the batched path.) - dedup unsafe FFI: factor the identical mmsghdr-from-iovec construction out of send_batch + recv_batch into one `mmsghdrs()` helper — the raw-pointer scaffolding + its lifetime SAFETY note now live in one place. - docs: TARGET_SOCKBUF no longer calls paced sending future work (it landed, m3.rs::paced_submit); gamescope.rs input is no longer "(TODO)" (wired + live-validated); the PUNKTFUNK_PERF `wire_mbps` field is renamed `tx_mbps` and noted as attempted/sealed bytes (send_dropped shows what didn't reach the wire). Full suite (35 + loopback round-trip + 6) + clippy + fmt green. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> |

perf(latency): microburst-cap pacing + per-frame latency histogram
ci / rust (push) Has been cancelled
From the latency investigation: the freeze-fix pacing (paced_submit) was the single biggest software-controllable latency term — it unconditionally spread EVERY multi-chunk frame over ~90% of the frame interval, adding up to ~7.5 ms @120 / ~15 ms @60 to a frame's last packet even when the frame was small or the link idle. Recover that on the common case while keeping the freeze fix: - Microburst-cap pacing: a frame whose sealed size is <= a cap (default 128 KB, PUNKTFUNK_PACE_BURST_KB) goes out in ONE immediate burst — no pacing latency. Only the OVERFLOW of a bigger frame (IDR / sustained high bitrate, the bursts that actually overran the tx buffer and froze) is spread. 128 KB is well under the ~150 Mbps@60 frame size where drops began, so the default is safe; raise it after confirming send_dropped stays 0 on a given link. Still never slower than unpaced (budget collapses to 0 with no slack). seal-once/in-order nonce preserved — chunks are split, never reordered or re-sealed. - Per-frame instrumentation (PUNKTFUNK_PERF, zero-cost off): encode_us + pace_us (the pacing tail) p50/p99/max histograms + immediate-vs-paced frame counts in the periodic perf line, so the pacing tail is finally visible and the cap is tunable against real numbers. Host builds + clippy + fmt green. NOT yet deployed to the running hosts (still on the safe full-pacing A+B build) — needs the user's LAN soak to validate the cap doesn't reintroduce send_dropped before raising it. Deferred bigger bets (need real-NIC/GPU/Mac validation): encode|send thread split on the native path, CUDA stream+event (one redundant sync), NVENC slice wrapper, stage-2 Apple presenter, glass-to-glass probe — see docs/roadmap.md.

feat(1gbps): pace per-frame sends so high-bitrate frames don't burst-drop
ci / rust (push) Has been cancelled
Increment B of the send-path rework — the actual fix for "freezes get more common over ~150 Mbps, no image at all at 400 Mbps" on the native path. Cause: the encoder emits a frame and submit_frame blasted ALL its packets at once into the NIC; a real link drops the line-rate burst (host send buffer EAGAINs), and under infinite GOP one dropped frame freezes the decode until the next keyframe. (The speed-test probe showed 0 drops at 400 Mbps because the probe is self-paced; real video wasn't.) Adaptive pacing, no extra thread, no regression: - Session splits into seal_frame (FEC + packetize + seal → wire packets, no send) and send_sealed (one batched sendmmsg of a chunk, counts drops); submit_frame is now their composition (synthetic + probe paths unchanged). - virtual_stream's paced_submit seals a frame then sends it in 16-packet chunks spread over ~90% of the time until the next frame is due. At 60 fps desktop (fast encode → lots of slack) the frame spreads across the interval → no NIC burst → no freeze. At 240 fps@5K (encode ≈ interval → ~0 slack) the budget collapses and every chunk goes out immediately → never slower than before. Core suite (34 + loopback round-trip + 6) + clippy + fmt green. The seal/send split is covered by the existing loopback tests; the pacing is host timing, verified by review (live-test needs a real NIC — your Mac at a raised bitrate).

feat(1gbps): raise bitrate/probe clamps + socket buffers, count send-buffer drops
ci / rust (push) Has been cancelled
First step of 1 Gbps+ readiness (the whole point of the GF(2^16) Leopard FEC): make 1 Gbps configurable and its dominant failure mode observable, before the real transport work (sendmmsg + paced encode|send split) lands. Investigation (6-way) verdict: we're ~halfway, and it's mostly clamps plus one real piece of work. The integer/type path, FEC (a 1 Gbps frame is only a few hundred shards in one GF(2^16) block, far under the 65535 ceiling), AES-GCM (AES-NI, ~10-25x headroom), and the M1 reassembler bounds (fully derived from the negotiated FecConfig) are ALL already 1 Gbps-ready and untouched. This commit (the configurable + observable foundation): - m3.rs: MAX_BITRATE_KBPS 500_000 -> 2_000_000 (2 Gbps headroom over the 1 Gbps+ target); MAX_PROBE_KBPS 1_000_000 -> 3_000_000 (probe can demonstrate headroom ABOVE the session cap so a client can confidently pick a 1 Gbps+ bitrate). - transport/udp.rs: TARGET_SOCKBUF 8 MB -> 32 MB (a multi-MB IDR keyframe burst no longer fills the buffer); scripts/99-punktfunk-net.conf bumped to match. - Observability: Transport::send now returns Ok(true|false) (false = WouldBlock send-buffer drop, previously a silent Ok(())). Session counts these as a new `packets_send_dropped` stat (distinct from recv-side packets_dropped) — in Stats, the C ABI PunktfunkStats (header regenerated), a PUNKTFUNK_PERF periodic wire-Mbps + drop dump in virtual_stream, and the speed-test probe completion log. This is the dominant 1 Gbps+ loss mode and was invisible. Loopback-verified: a probe now runs at 1.2 Gbps target (no longer truncated to 1 Gbps) with the drop counter live. NOT yet a sustained-1-Gbps proof — the single-send()-per-packet native path is the next, real piece of work (port the proven GameStream sendmmsg + paced send thread into the core Transport).

feat(host): log virtual DualSense pad creation (match the X-Box path)
ci / rust (push) Has been cancelled
The uinput X-Box 360 backend logs "virtual gamepad created" on success, but the UHID DualSense backend logged only on failure — so a working DualSense session was silent and indistinguishable in the logs from one where no pad was ever created. Add the matching success log. This makes a DualSense-not-working report self-diagnosing: the host now logs either "virtual DualSense created (UHID hid-playstation)" or the existing "virtual DualSense creation failed — controller input disabled" (which fires when /dev/uhid isn't writable — i.e. the 60-punktfunk.rules uhid rule isn't installed or the user isn't in the 'input' group).

feat(punktfunk/1): negotiable encoder bitrate + bandwidth speed-test probe
ci / rust (push) Has been cancelled
Two related additions to the native protocol, host-side (the client side of
each is exposed over the C ABI so the platform clients can wire it up).
Bitrate negotiation
- Hello/Welcome carry `bitrate_kbps` (appended trailing-byte field, back-compat:
old peers decode 0 = host default). The client requests a rate; the host
clamps it to [500 kbps, 500 Mbps] (or its 20 Mbps default when 0) and echoes
the resolved value in Welcome. Replaces the hardcoded 20 Mbps NVENC bitrate in
m3.rs — threaded through virtual_stream → build_pipeline → open_video, applied
on the initial mode and every reconfigure rebuild.
- C ABI: punktfunk_connect_ex3(..., bitrate_kbps, ...) (ex2 delegates with 0);
punktfunk_connection_bitrate() reads the resolved value.
Speed test (bandwidth probe)
- New typed control messages ProbeRequest{target_kbps,duration_ms} (0x20) /
ProbeResult{bytes_sent,packets_sent,duration_ms} (0x21), plus a FLAG_PROBE
packet flag. The client asks the host to burst zero-filled, FLAG_PROBE-tagged
access units over the data plane at a target goodput for a duration (clamped
≤ 1 Gbps / ≤ 5 s), pacing by a bytes-allowed budget; video pauses for the
burst. The host reports what it actually sent; the client measures received
bytes + window → goodput and loss. Probe filler is never fed to the decoder
(diverted in the connector pump and the reference client's poll loop).
- The host control task now multiplexes Reconfigure + ProbeRequest (inbound)
and ProbeResult (outbound) over select!; a probe channel reaches the
data-plane thread (both virtual and synthetic sources).
- Connector: NativeClient::request_probe()/probe_result() with an internal
accumulator; C ABI punktfunk_connection_speed_test() +
punktfunk_connection_probe_result() → PunktfunkProbeResult.
- punktfunk-client-rs gains `--bitrate KBPS` and `--speed-test KBPS:MS` (its own
loop measures + logs goodput/loss) for loopback verification.
Validated on loopback (synthetic source): a 20 Mbps / 2 s probe measured
20050 kbps at 0% loss, bitrate negotiated (0→20000 and 50000→50000), and the
interleaved probe AUs were correctly excluded from frame verification
(mismatched=0). Wire codecs + trailing-byte back-compat have unit tests. C
header regenerated.

feat(host): host-managed gamescope session at the client's mode (dynamic res + refresh)
ci / rust (push) Has been cancelled
Nested games on the Bazzite host saw the wrong display: refresh capped at 60 Hz, the box's connected TV's EDID modes leaking in (DOOM landed on 2560×1440@60), and the resolution fixed at whatever the always-on session was launched at — the client's requested mode never reached the game. Root causes: the session-plus gamescope command has no --nested-refresh (Xwayland advertises 59.96 Hz for every mode), --prefer-output HDMI-A-1 makes gamescope read the TV EDID, and the ATTACH model launches one fixed-resolution session. New vdisplay path: PUNKTFUNK_GAMESCOPE_SESSION=<client> — the host LAUNCHES gamescope-session-plus headless AT THE CLIENT'S mode and relaunches it when the mode changes. Injected via a host-written GAMESCOPE_BIN wrapper (--nested-refresh $PF_HZ, the flag session-plus doesn't expose) + DRM_MODE=cvt (gamescope generates clean CVT modes at that refresh instead of the TV's EDID). The session runs as a transient `systemd-run --user` unit (clean cgroup teardown of the Steam tree); state lives in a host-lifetime static (MANAGED_SESSION), NOT in GamescopeDisplay (which is per-client-session) — so a same-mode reconnect REUSES the running session instantly (no Steam restart) while a different mode RELAUNCHES it (games can't change output mode live; a game/Steam restart on a mode change is unavoidable and acceptable). Reuses the existing node + EIS auto-discovery (find_gamescope_node / find_gamescope_eis_socket, factored into point_injector_at_eis) and the existing mid-stream Reconfigure → vd.create(mode) machinery — no protocol or m3 control-flow change. Validated live on bazzite (RTX 4090): games' Xwayland now advertises 5120×1440 @ 239.90 Hz as the preferred mode (was 59.96), the TV's 3840×2160/4096×2160@60 modes are gone, frames stream; reconnect at 1920×1080@120 relaunches and games see that; same-mode reconnect reuses with no restart and frames flow instantly. scripts: host.env.example documents PUNKTFUNK_GAMESCOPE_SESSION (mutually exclusive with the legacy NODE=auto attach); punktfunk-steam-session.service marked deprecated (superseded — must not run alongside the host-managed path).

feat(gamepad): controller discovery + client-negotiated pad type + rich DualSense end to end
The Apple client grows full gamepad support and punktfunk/1 learns to negotiate the virtual pad type: - Protocol: Hello carries a GamepadPref byte (offset 21, the same trailing-byte back-compat pattern as the compositor; echoed resolved in Welcome at 54). Host precedence: explicit client choice > PUNKTFUNK_GAMEPAD env > Xbox 360, DualSense (UHID) only where available. ABI: punktfunk_connect_ex2 + punktfunk_connection_gamepad (connect_ex delegates; ABI_VERSION stays 2 — the trailing byte IS the compat mechanism). punktfunk-client-rs gets --gamepad. - Swift client: GamepadManager (app-lifetime discovery + selection — Settings lists every controller with capabilities/battery/"In use"; exactly ONE pad forwards as pad 0, auto = most recently connected, or pinned), GamepadCapture (snapshot-diff button/axis events, DualSense touchpad + ~250 Hz motion on the rich-input plane, held state released on switch/deactivate/stop), GamepadFeedback (rumble → CoreHaptics per-handle engines; lightbar → GCDeviceLight; player LEDs → playerIndex; adaptive-trigger blocks → the table-driven DualSenseTriggerEffect parser → GCDualSenseAdaptiveTrigger, exact for the 10-zone positional modes). The pad type auto-resolves from the physical controller at connect time, user-overridable in Settings. - Host DualSense fixes surfaced by adversarial review against hid-playstation / SDL / Nielk1 ground truth: input-report sensor/touch offsets were off by one (the kernel read garbage motion + phantom touches), the L2/R2 trigger blocks were swapped (the report is right-trigger-first), feedback now gates on the report's valid-flags (a plain rumble write no longer blanks lightbar/ triggers), and the touchpad rescale clamps to the advertised ABS_MT extents. - Tests: Hello/Welcome trailing-byte back-compat, pick_gamepad precedence, byte-exact input-report layout, valid-flag gating, per-mode trigger-parser table (incl. packed 3-bit zones), wire conversions, and a scripted loopback feedback burst (PUNKTFUNK_TEST_FEEDBACK=1) asserted through the xcframework on the rumble + HID-output planes. Validated: cargo test/clippy/fmt green on macOS + Linux (61 host tests), swift build/test green, test-loopback.sh green, tvOS/iOS targets compile. DualSense motion sign/scale is derived from the calibration blob, not yet live-verified (constants isolated in GamepadWire). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> |

feat(host): attach to a running gamescope session (Bazzite headless Steam)
Bazzite (and SteamOS-like hosts) run Steam Big Picture inside their OWN gamescope-session-plus session. Nesting a second gamescope+Steam can't work — the second Steam sees the first and exits, taking the nested gamescope down with it (crash in its exit handlers), killing both video and input. The robust model is to let punktfunk OWN that session: run gamescope-session-plus headless at the client's resolution (full Steam Deck UI polish: MangoApp, VRR, controller config) and have the host ATTACH to it rather than spawn its own. The video half already existed (PUNKTFUNK_GAMESCOPE_NODE=<id> attaches to a PipeWire node). This finishes it: - PUNKTFUNK_GAMESCOPE_NODE=auto discovers the gamescope Video/Source node, so the (dynamic) node id needn't be hand-wired. - The attach path now also points the libei injector at the running session's EIS socket: find_gamescope_eis_socket() scans XDG_RUNTIME_DIR for gamescope-<N>-ei, connect()-probes each (stale dead-session sockets refuse), and writes the newest live one to the relay file the injector reads. So input reaches the attached session with zero manual config. scripts/punktfunk-steam-session.service: a systemd --user unit that runs gamescope-session-plus headless at a configured resolution, with the one-time headless-appliance setup (linger + multi-user.target) documented inline. Validated live on bazzite (RTX 4090): the full Steam Big Picture session streams (1499 frames, p50 ~1ms) with mouse/keyboard injected into it (device resumed, all caps, emitted=true), node + EIS socket both auto-detected.

fix(inject): self-heal a stale/hung EIS connection + per-kind injection diagnostics
The host-lifetime libei injector could connect to a gamescope EIS socket whose listen socket exists but whose server never drives the EI handshake — a stale socket left by a SIGKILLed prior session, or one created early in a new gamescope's startup before its libei server is ready. `UnixStream::connect` to a socket *file* succeeds the moment the path exists, so the worker sailed past the connect and then hung forever in `handshake_tokio` (or sat connected with no device ever resumed). Because `LibeiInjector::inject` only enqueues onto a channel (the !Send worker owns the connection), the send never errors, so InjectorService never noticed the dead worker and never reopened — every input event for the whole session was silently swallowed. The 30s setup timeout didn't help: a typical session ends first, so input just died with no error logged. Reconnecting made it worse (more stale sockets to land on). Two self-heal bounds, both paths (gamescope socket + KWin/GNOME portal): - Bound the EI handshake at 8s — a non-responding EIS server now errors instead of hanging, so the worker exits and the next inject() reopens. - Watchdog: if no input device resumes within 5s of connecting, treat the connection as dead-on-arrival and exit (same reopen path). Healthy servers add+resume a device within a beat of the handshake. Verified on-box: clean gamescope + KWin paths connect/resume/emit unchanged; a stale listener that accepts-but-never-handshakes now errors in 8s; two back-to-back gamescope sessions both inject (session 2 reopens against the fresh socket). Independently confirmed end-to-end delivery on KWin — a focused wev got the injected motions/keys/buttons — i.e. injection itself was never broken, only its recovery from a bad connection. Also adds permanent low-volume diagnostics so the next "input dead" report is instantly triageable: log each EIS device's capabilities on resume, the first of each InputKind a client sends + whether it emitted, and no-resumed-device drops.

fix(inject): make the gamescope EIS injector reconnect robustly across sessions
ci / rust (push) Has been cancelled
Root cause of "input doesn't work" on the unified host: a single fresh session injects fine (EIS connects, "Gamescope Virtual Input" device added), but the host-lifetime injector reused a STALE per-session EIS socket across sessions → "connect EIS socket …: Connection refused". (Headless gamescope is EIS-only — it ignores uinput — so libei/EIS is the one input path for both gamescope and KWin; no second path needed.) - connect_socket_file: re-READ the relay file and RETRY the connect on refused/missing (the live gamescope's EIS appears shortly), bounded at 15s, instead of connecting once and bubbling ECONNREFUSED. - GamescopeProc::drop: clear the relayed EIS socket name on teardown so a dead session can't hand a stale path to the next reconnect. Validated: two sessions back-to-back each reconnect (EIS connected + device added). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> |

feat(host): §8a — require native pairing by default (serve --open to disable)
ci / rust (push) Has been cancelled
An open punktfunk/1 host any LAN device can trust-on-first-use and stream from is
insecure. The unified host now gates native sessions on pairing by DEFAULT: a client
must complete the SPAKE2 PIN ceremony (armed from the web console) before it's
admitted; paired devices persist. `serve --open` keeps the old TOFU behavior for
trusted single-user setups.
native_serve_opts now takes a NativeServe { port, require_pairing }; parse_serve
builds it with require_pairing = !--open. GameStream pairing (separate) is unchanged.
The require_pairing gate + ceremony are already covered by m3::pairing_ceremony_and_gate.

feat(host): unified host + native pairing over the management API
`serve --native` now runs the GameStream host AND the native punktfunk/1 (QUIC) host in ONE process, sharing a single NativePairing handle with the management API — so native pairing is operable from the web console instead of journalctl. - gamestream::serve gains a native_port: spawns crate::m3::serve in the same runtime and passes the shared NativePairing to mgmt::run. Validated live: one process binds both RTSP 48010 and QUIC 9777. - mgmt API: new `native` endpoints — GET /native/pair (status), POST /native/pair/arm (mint a fresh, time-limited PIN to DISPLAY), DELETE /native/pair (disarm), GET/DELETE /native/clients (list/unpair). GameStream-only hosts report enabled:false. OpenAPI regenerated (checked-in doc + drift test). - main.rs: serve --native / --native-port flags. The native host arms pairing on demand (the operator reads the PIN from the console; the SPAKE2 ceremony is host-shows-PIN). New mgmt + native_pairing tests.

refactor(native-pairing): extract shared on-demand arming state
Groundwork for web-UI-driven native (punktfunk/1) pairing. Replaces m3's fixed startup PIN + local paired store with a shared `NativePairing` (new module): arm-on-demand with a fresh, time-limited PIN (`arm(ttl)`), `current_pin()` read per ceremony so a lapsed window stops pairing, plus the trust store (list/add/ remove/is_paired) and a `status()` snapshot. The management API (next commit) and the QUIC accept loop share one handle. CLI `--allow-pairing`/`--require-pairing` still arm at startup (no expiry, PIN logged) — back-compat. m3 pairing ceremony + gate and the C-ABI roundtrip stay green; new unit tests for arm/expire/pair.

build: support FFmpeg 7.x and 8.x; fix RPM spec GPU link deps
ci / rust (push) Has been cancelled
punktfunk-host builds unchanged against either FFmpeg 7.x (libavcodec 61) or 8.x (libavcodec 62) — ffmpeg-sys-next auto-detects the system version, and the host's ffmpeg FFI only touches long-stable APIs. Confirmed by building + running live on a Bazzite F43 box (FFmpeg 7.1.3): full gamescope capture → zero-copy dmabuf→CUDA → NVENC H.265 at 1280x720x60, p50 ~0.96 ms. Just doc/spec accuracy, no code change: - encode/linux.rs + CLAUDE.md: drop the "FFmpeg 8 only" claim; note 7.x/8.x both work. - rpm spec: add the missing zero-copy GPU build deps the link actually needs — pkgconfig(gl) + pkgconfig(gbm) (mesa) — and document that -lcuda needs libcuda.so at link time (NVIDIA host, or the CUDA toolkit stub on a headless COPR/koji builder). Tracked for a proper fix: make the cuda/gbm/GL FFI dlopen-based like khronos-egl so the RPM builds on a GPU-less host. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> |

feat(dualsense): Phase C/D/E — virtual DualSense routing + 0xCC/0xCD planes + C ABI
ci / rust (push) Has been cancelled
PUNKTFUNK_GAMEPAD=dualsense now routes a session's gamepad through a real virtual
DualSense (UHID + hid-playstation) end to end:
- host: a `PadBackend` enum (m3.rs) selects `GamepadManager` (uinput xpad, default)
or the new `DualSenseManager` (dualsense.rs) per session. The manager keeps each
pad's full DsState so touchpad + motion (rich-input plane) persist across
button/stick frames, and services the !Send /dev/uhid fd only on the input thread
(which cycles <=4ms, so the GET_REPORT init handshake completes).
- feedback: `service()` now returns `DsFeedback { hidout, rumble }`. Motor rumble
stays on the universal 0xCA plane (so non-DualSense clients still feel it; manager
dedups change); lightbar / player LEDs / adaptive-trigger effects ride the new
0xCD HID-output plane (host->client) as `HidOutput`.
- rich input: touchpad contacts + motion ride the 0xCC plane (client->host) as
`RichInput`, applied via `DualSenseManager::apply_rich` (merged with button state;
touch normalized 0..65535 -> the touchpad resolution).
- connector + C ABI: `NativeClient::next_hidout` / `send_rich_input`, exported as
`punktfunk_connection_next_hidout` (-> PunktfunkHidOutput) and
`punktfunk_connection_send_rich_input` (<- PunktfunkRichInput); header regenerated.
- reference client: `--rich-input-test` drives the DualSense touchpad + motion and
logs the 0xCD feedback that comes back.
Validated live on-box: a synthetic-source m3-host + client-rs created the real
kernel DualSense, drove 0xCC, and decoded 12 live 0xCD events (the kernel's actual
lightbar/trigger init reports) with the data plane unaffected (600/600 frames).
Adversarial review fixes folded in: the input loop no longer skips the rich drain +
feedback pump on a dropped gamepad event, and the touch contact id is clamped to its
slot. Remaining: the Apple client renders triggers/rumble on a real DualSense.

feat(host): virtual DualSense via UHID (hid-playstation) — device + report mapping
ci / rust (push) Has been cancelled
Roadmap #5 (rich DualSense). A UHID device presents a real Sony DualSense to the kernel's hid-playstation driver (matched by VID 054C/PID 0CE6), which exposes the full controller — gamepad, motion sensors, touchpad, lightbar/player LEDs, adaptive triggers — unlike the uinput X-Box-360 pad. - inject/dualsense.rs: hand-rolled /dev/uhid codec (no bindgen) mirroring the uinput style; the canonical inputtino 232-byte USB HID report descriptor + the feature-report replies (calibration 0x05 / pairing 0x09 / firmware 0x20) — answering hid-playstation's GET_REPORTs during init is REQUIRED or it creates no input devices. DsState::from_gamepad maps a GameStream/XInput frame → the DualSense input report (buttons/sticks/triggers/dpad, + touchpad/motion fields); service() answers GET_REPORTs and parses HID OUTPUT (rumble / lightbar RGB / player LEDs / adaptive triggers) into quic::HidOutput. - scripts/60-punktfunk.rules: grant /dev/uhid to the 'input' group (like /dev/uinput). - `punktfunk-host dualsense-test`: standalone validation (no streaming session). Validated live: `dualsense-test` → hid-playstation binds + loads ff_memless + led_class_ multicolor; the kernel creates "Punktfunk DualSense 0" (event/js gamepad + Motion Sensors + Touchpad + Headset Jack) at VID 054c/PID 0ce6, plus the lightbar at /sys/class/leds/ input*:rgb:indicator; js shows the Cross button firing + the left-stick sweep. Clippy/fmt clean, workspace tests green. Wiring into the session (pad-type select, touchpad/motion routing, HID-output back-channel) is the next commit.

fix: keep the workspace green on macOS after the mic/touch/rich-input batch
The new features were Linux-built only and broke the documented macOS gate (cargo build/test/clippy --workspace) four ways, all fixed following the existing platform-gating conventions: - m3.rs: mic_service_thread split into the Linux worker and a non-Linux stub that drains and drops (sessions still count the datagrams) — opus/PipeWire are Linux-gated deps, same pattern as audio_thread. - punktfunk-client-rs: the new `opus` dependency moved into the Linux target table and --mic-test gated with a warn-and-skip stub (only the synthetic-tone test rig needs the encoder; the mic uplink itself is portable). - gamestream/audio.rs: SAMPLE_RATE import gated to any(linux, test) (the frame_sizing test uses it everywhere, the data plane only on Linux). - tests/c_abi.rs: the harness's macOS link flags gained Security + CoreFoundation — the quic feature now pulls rustls's platform verifier into the staticlib. Also: two clippy match-ref-pats lints in the new rich-input/HID-output decoders (clippy -D warnings is the repo gate), the regenerated punktfunk_core.h committed (the checked-in copy predated the rich-input/HID-output constants — CI fails on drift), and web's inlang cache dir gitignored. cargo build/test/clippy/fmt --workspace: green on macOS, 122 tests passing.

feat: touch input — TouchDown/Move/Up + host libei ei_touchscreen injection
ci / rust (push) Has been cancelled
Roadmap #5 (touch, ahead of the XL UHID DualSense work). Touch fits the existing 18-byte InputEvent: code = touch id, x/y = client pixels, flags = (w<<16)|h — the same absolute mapping as MouseMoveAbs. - core: InputKind::{TouchDown=9, TouchMove=10, TouchUp=11} + from_u8 + roundtrip test. - host inject/libei.rs: request the RemoteDesktop Touchscreen device type, bind the Touch capability, and inject ei_touchscreen down/motion/up (one event = one frame, per the protocol rule), mapping coordinates into the device region like the abs pointer. wlroots has no virtual-touch protocol wired — no-ops there. - client-rs --touch-test: drags a synthetic finger (touch id 0) in a circle. Validated live on headless KWin: the portal GRANTS the Touchscreen device type (Keyboard|Pointer|Touchscreen), proving the request path — but KWin's EIS server creates no touchscreen *device*, so touch currently no-ops on this KWin (now logged once, not silent). The injection code is correct and will land on a backend that exposes ei_touchscreen (gamescope / a newer compositor / the real touch-client path). Workspace green, clippy/fmt clean, +1 unit test.

feat: mic passthrough — client microphone → host virtual PipeWire source
ci / rust (push) Has been cancelled
The inverse of the host→client audio path: the client's mic, Opus-encoded, rides a new 0xCB QUIC datagram to the host, which decodes it into a virtual PipeWire Audio/Source its apps can record from (voice chat, etc.). Protocol (punktfunk-core): - MIC_MAGIC 0xCB + encode/decode_mic_datagram (mirror of the 0xC9 audio datagram). - NativeClient::send_mic(seq, pts_ns, opus) over a new outbound channel + worker task (mirror of send_input); C ABI punktfunk_connection_send_mic for native clients. Host: - audio::VirtualMic + PwMicSource: a PipeWire output stream tagged media.class= Audio/Source (Direction::Output) — a recordable microphone node, fed decoded PCM. - MicService: host-lifetime owner of the source + Opus decoder (mirror of InjectorService / the audio capturer slot); lazily opened, persists across sessions, self-heals. The per-session datagram reader now demuxes 0xCB→mic / 0xC8→input over a single read_datagram loop (two loops would race). - Adaptive jitter buffer in the producer: primes to ~3 consumer quanta before emitting, so the 5 ms push / N ms pull clock skew never underruns — without it ~58% of output was silence; with it, glitch-free across consumer quanta. Client: punktfunk-client-rs --mic-test streams a synthetic 440 Hz Opus tone as the mic uplink (opus dep added) for end-to-end validation without a real microphone. Validated live on headless KWin: client tone → host source → pw-record shows the punktfunk-mic Audio/Source node, 440 Hz dominant (Goertzel power 20.7 vs <0.001 elsewhere), RMS 0.179 ≈ the ideal 0.177, 0.3–0.4% silence at both 256 ms and 10 ms consumer quanta. Tests +1 (mic datagram roundtrip); workspace green, clippy/fmt clean. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> |

fix(m3): persistent host-lifetime input injector — end the RemoteDesktop portal churn
ci / rust (push) Has been cancelled
Under rapid client reconnects, KWin's libei/EIS input setup intermittently wedged with "EIS setup timed out", causing total input loss for affected sessions. Root cause: each punktfunk/1 session opened (and tore down) its own RemoteDesktop-portal CreateSession for pointer/keyboard injection, and back-to-back reconnects raced a prior session's portal teardown before it settled. LibeiInjector is only a Send channel handle to a worker thread that owns the portal session, so the injector can live for the whole host run instead of per session. Adds InjectorService: one host-lifetime thread owns the (!Send) injector, opened ONCE (lazily, on the first event) and reused across every session — the portal grant is established a single time and held. Sessions forward pointer/keyboard events to it over a clonable Send channel; gamepads stay per-session (uinput, no portal). The service self-heals — reopen after a 2s backoff if open fails or the backend worker dies (covers a gamescope EIS socket that respawns with its nested session). Mirrors the existing host-lifetime audio-capturer slot; the audio capturer is Send (a slot works), the injector is !Send (needs the owning thread + channel). Validated live on headless KWin: 8 rapid back-to-back input sessions → "input injector ready (host-lifetime)" exactly once, ZERO "EIS setup timed out", 8/8 sessions injected input. Tests green, clippy/fmt clean. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> |

feat: client-selectable compositor (protocol → host → client → C ABI → mgmt → web)
A client can now request which compositor backend the host drives its virtual
output on (gamescope/KWin/Mutter/wlroots). The host honors the request if that
backend is available, else falls back to auto-detect and reports the resolved
choice back — wire-compatible both directions (no ABI bump).
Protocol (punktfunk-core):
- New CompositorPref (config.rs): Auto|Kwin|Wlroots|Mutter|Gamescope with
u8/name mappings. Appended as one optional byte to Hello (client preference)
and Welcome (host's resolved choice). Both decoders already tolerate trailing
bytes, so old↔new interop is preserved — ABI_VERSION stays 2. Round-trip +
back-compat (truncated-message) tests.
- C ABI: punktfunk_connect_ex(compositor) + PUNKTFUNK_COMPOSITOR_* constants;
punktfunk_connect delegates with AUTO, so the existing symbol is unchanged.
NativeClient::connect / worker_main thread the preference through.
Host:
- vdisplay::available() enumerates usable backends via cheap, side-effect-free
probes (KWin zkde global, gamescope binary+version, GNOME/Sway env), plus
Compositor id/label/as_pref/from_pref/all helpers.
- m3 handshake resolves the preference to a concrete backend during the
handshake (pick_compositor pure + resolved logging), reports it in Welcome,
and threads it into virtual_stream (replacing the unconditional detect()).
- mgmt GET /v1/compositors lists every backend with availability + the
auto-detected default (OpenAPI regenerated).
Client:
- punktfunk-client-rs --compositor NAME; logs the host's resolved choice from
the Welcome ("session offer … compositor=…").
Web console:
- Host page gains a Compositors card (availability + default badges) via the
codegen'd useListCompositors hook; en/de strings added.
Also fixes a pre-existing, env-dependent test-isolation bug:
mgmt::tests::paired_clients_list_and_unpair seeded the real
~/.config/punktfunk/paired.json (AppState::new loads it), so a real
GameStream-paired client leaked into body[0] on a dev box — now cleared first.
Live-validated against headless KWin: --compositor kwin honored, --compositor
mutter falls back to kwin (available=[kwin, gamescope]), resolved choice
round-trips to the client. Tests: +6 (wire/back-compat, resolution precedence,
endpoint); workspace green, clippy/fmt clean, C ABI harness PASS at abi_version=2,
web typecheck + build clean.

feat(host): KDE-reliability phase 2 — pipeline retry, graceful capture teardown, refresh reconcile
Hardens the virtual-display → capture → encode bring-up against the transient failures that surfaced as black screens / wrong refresh on cold KDE sessions. - m3: build_pipeline_with_retry wraps the initial vd.create() + first-frame with bounded exponential backoff (4 attempts, 500ms→2s). is_permanent_build_error classifies config/version/missing-tool failures so they fail fast instead of burning the retry budget. Encoder + frame clock now pace to the *achieved* refresh reported in VirtualOutput::preferred_mode, not the requested rate. - capture/linux: PortalCapturer::Drop sends a pipewire channel quit and joins the thread, so a dropped/failed/retried capturer releases its PipeWire thread + EGL/ CUDA context promptly instead of leaking it to process exit. First-frame timeout now reports the node id and distinguishes "format never negotiated" from "negotiated but no buffers arrived" via a negotiated flag set in param_changed. - vdisplay/kwin: set_custom_refresh reads back the active mode from kscreen-doctor and returns the refresh KWin actually gave us (a rejected custom mode silently leaves the output at 60Hz); create() carries it into preferred_mode. - vdisplay/gamescope: find_gamescope_node requires the Video/Source object (the node.name=gamescope tag is on two objects; the other wedges the link); a version check warns on <3.16.22 (the PipeWire-1.6 capture-deadlock signature). Live-validated against headless KWin: 720p120 build with requested=120 achieved=120, zero-copy CUDA frames, and no per-session thread accumulation across back-to-back sessions. Tests: +3 unit (retry classifier, gamescope version parse); 49 host tests green, clippy/fmt clean. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> |

feat(headless-kde): reliable bring-up — readiness probe, fix portal ordering/env (roadmap #1 phase 1)
ci / rust (push) Has been cancelled
Headless KDE startup was a chain of timing-sensitive handoffs gated by a blind `sleep 2`, the dominant source of black screens. Phase-1 fixes: - New `punktfunk-host probe-compositor` subcommand: exits 0 iff the detected compositor is up AND ready to create a virtual output now. KWin gets a real check (connect + registry roundtrip + the privileged zkde_screencast global must be advertised — what the backend needs); gamescope/Mutter/wlroots create on demand so the probe just confirms Linux. (vdisplay::probe dispatcher + kwin::probe; reuses kwin.rs's existing roundtrip path.) - run-headless-kde.sh: replace `sleep 2` with an active readiness wait (poll probe-compositor until ready, 30s deadline, and bail with kwin's log if kwin_wayland exits during init). Move the portal restart to AFTER readiness, and precede it with `systemctl --user import-environment` + `dbus-update-activation-environment` (the missing env import — the Sway script does this; without it a restarted portal inherits a stale/empty WAYLAND_DISPLAY, which is the "streams but eats no input/audio" failure). kwin's stderr → a log file. Validated: probe-compositor exits 0 "Kwin ready" against the live session, exit 1 with a clear diagnostic when the compositor is absent. 114 tests green, clippy/fmt clean.

fix(punktfunk/1): adversarial-review fixes — SPAKE2 pairing, renegotiation hardening, +more
ci / rust (push) Has been cancelled
Triaged the multi-agent review of the renegotiation + pairing + Sway + AV1/surround batch
(1 critical, 11 major/minor confirmed). Fixes:
CRITICAL — PIN pairing was offline-brute-forceable. The HMAC-of-PIN proof let an active
MITM who terminates the TOFU ceremony recover the 4-digit PIN by offline dictionary search
(all other inputs observable) and forge a correctly-bound proof. Replaced with **SPAKE2**
(balanced PAKE, `spake2` crate) + key-confirmation MACs, binding both cert fingerprints as
the SPAKE2 identities: an attacker gets exactly ONE online guess, no offline search, and
mismatched cert views (a real MITM) never reach a shared key. Also reworked the UX to an
"arming PIN" — one PIN per arming window shown at host startup (the SPAKE2 client needs the
PIN to build its first message, so it can't be minted per-connection). Validated live:
wrong PIN rejected in 0.1s, right PIN pairs + persists + the paired identity streams.
Pairing hardening: `--allow-pairing`/`--require-pairing` must arm pairing (default rejects
unsolicited ceremonies); per-host cooldown bounds online guessing; the client flushes its
CONNECTION_CLOSE so a refused ceremony can't wedge the sequential host for the full timeout;
atomic (temp+rename) paired-store writes.
Protocol: control/pairing messages use a distinct CTL_MAGIC (PKFc) — fully disjoint from
the positional Hello namespace (a future abi_version can't be misparsed as a control
message); all typed decodes are length-exact. ABI_VERSION → 2 (punktfunk_connect signature
gained the identity params; header regenerated).
Renegotiation: drain the reconfig channel to the NEWEST mode (one rebuild, not one per
stale step); validate refresh_hz; build the new pipeline BEFORE dropping the old so a
rebuild failure keeps the session on its current mode instead of killing it.
GameStream: packetDuration snaps to {5,10} (an in-between value isn't a legal Opus frame
size and would kill audio). Sway: chooser file moved to $XDG_RUNTIME_DIR (was a fixed
world-writable /tmp path — DoS / capture-misdirection by another local user).
Swift: fixed two compile breakers in the new pairing/identity APIs (Int32 status .rawValue,
UInt cap cast). New SPAKE2 + namespace-disjointness + pairing-roundtrip unit tests; the
in-process pairing test now also exercises the arming PIN + cooldown. 114 tests green,
clippy -D warnings clean (both feature sets), fmt, C-ABI harness.

feat: punktfunk/1 — mid-stream mode renegotiation + PIN pairing ceremony
Renegotiation (no reconnect on resize): the handshake bi-stream stays open; the client
sends Reconfigure{mode} (typed post-handshake message), the host validates + acks
Reconfigured and rebuilds capture/encoder/virtual output at the new mode while the data
plane (keys, ports, FEC) runs untouched — the first new-mode AU is an IDR with in-band
parameter sets. NativeClient::request_mode / punktfunk_connection_request_mode; mode()
reflects the active mode. Validated live on KWin: one continuous stream, 225 frames
@1280x720 then 395 @1920x1080, ~90 ms pipeline rebuild (ffprobe shows both resolutions).
PIN pairing (mutual trust, kills TOFU MITM): clients get persistent self-signed
identities presented via QUIC client auth (generate_identity / client auth offered but
optional server-side — legacy clients still connect). Ceremony on the control stream:
PairRequest{name} → host shows a 4-digit PIN (log) + PairChallenge{salt} → client proves
with HMAC-SHA256(PIN‖salt, client_fp‖host_fp) — binding both certs means a MITM can't
forward a proof, single attempt per PIN, constant-time compare → PairResult; host
persists the fingerprint (~/.config/punktfunk/punktfunk1-paired.json), client pins the
host's. m3-host --require-pairing gates sessions on the paired set.
NativeClient::pair + punktfunk_pair/punktfunk_generate_identity in the ABI; reference
client: --pair PIN --name LABEL + auto-generated persistent identity, --remode for live
renegotiation testing. Swift wrapper: ClientIdentity/generateIdentity()/pair(),
requestMode()/currentMode(); README handoff updated.
Tested: reconfigure/pairing wire roundtrips, C-ABI mode switch ack, full in-process
ceremony (wrong PIN → Crypto, anonymous-vs-gate rejection, success → pinned session);
live wrong-PIN ceremony against the serving host (PIN logged, proof rejected).

feat(gamestream): AV1 negotiation + 5.1/7.1 surround audio
Codec negotiation (M2 polish):
- ServerCodecModeSupport now advertises what we encode: H264|HEVC|AV1_MAIN8
= 65793 (flags verified against moonlight-common-c Limelight.h). The old
placeholder 3843 wrongly claimed HEVC Main10 + 4:4:4 and no AV1. Main10
bits stay off on purpose: Moonlight ties 10-bit to HDR, and capture is
8-bit SDR BGRx with no HDR metadata path (av1_nvenc -highbitdepth was
validated working for later).
- RTSP ANNOUNCE: bitStreamFormat 0/1/2 -> H264/HEVC/AV1 (already plumbed to
av1_nvenc; validated e2e via `m0 --codec av1` + ffprobe av01), and a
dynamicRangeMode!=0 request now logs + falls back to 8-bit SDR.
Surround audio (M2 polish):
- ANNOUNCE x-nv-audio.surround.{numChannels,AudioQuality} +
x-nv-aqos.packetDuration -> per-session AudioParams; DESCRIBE advertises
all six Opus configs (normal before HQ per channel count). Normal-quality
mappings are pre-rotated for the client's GFE-order LFE swap
(RtspConnection.c, verified verbatim) so its derived decoder mapping
equals our encoder mapping — including 7.1, where Sunshine's rotate only
covers [3,6) and scrambles LFE/SL/SR.
- 5.1/7.1 encode via libopus multistream (audiopus_sys, the sys layer the
opus crate already links) with Sunshine's layouts/bitrates, RAII wrapper;
the live-validated stereo wire is byte-identical (plain Opus, no FEC).
- Surround sessions add Sunshine-style RS(4,2) audio FEC (packetType 127 +
AUDIO_FEC_HEADER, the OpenFEC parity matrix both ends hardcode, nanors
gemm semantics verified from nanors/rs.c).
- PipeWire capture generalized to the negotiated channel count with explicit
FL FR FC LFE RL RR [SL SR] positions; missing sink channels are zero-
filled by the channel-mixer. PwAudioCapturer now tears down cleanly on
Drop (pipewire channel -> loop quit), so a channel-count change can
reopen without leaking a capture stream.
Tests: serverinfo mask, RTSP codec/audio param parsing, DESCRIBE contents,
surround-params strings + client-swap round trip, FEC parity self-recovery
and packet layout, real-codec 5.1 channel-identity round trip, and an
ignored live test (ran green against a 6ch null sink monitor).

feat(vdisplay): wlroots/Sway backend — swaymsg headless output + xdpw chooser
The fourth VirtualDisplay backend: `swaymsg create_output` adds a HEADLESS-N output (name found by diffing get_outputs), `output <NAME> mode --custom WxH@HzHz` sets the client's exact mode (and the refresh clock a fresh headless output needs to produce frames at all), and the PipeWire node comes from the ScreenCast portal. Headless output selection is non-interactive via xdg-desktop-portal-wlr's chooser hook: a managed config (chooser_type=simple, chooser_cmd cats /tmp/punktfunk-xdpw-output; portal try-restarted when the config changes) plus a per-session `Monitor: <NAME>` written to that file. Teardown is RAII: drop ends the portal thread (zbus connection drop ends the cast) then `swaymsg output <NAME> unplug`. swaymsg commands go after `--` so tokens like `--custom` reach sway instead of swaymsg's getopt. Validated live on headless sway 1.11 (gles2-on-NVIDIA, xdpw 0.8.1), zero-copy dmabuf→CUDA on both runs: 720p60 257 frames p50 0.77 ms, 1080p60 480/480 frames p50 1.18 ms, output unplugged with the session both times. The checked-in xdpw.config sample now matches the managed config (the old chooser_type=none/HEADLESS-1 form would pin capture to the wrong output).

rename: lumen → punktfunk, everywhere
ci / rust (push) Has been cancelled
Full project rename, decided 2026-06-10: - Crates/binaries: punktfunk-core / punktfunk-host / punktfunk-client-rs. - C ABI: punktfunk_* symbols, Punktfunk* types, include/punktfunk_core.h, PUNKTFUNK_FEATURE_QUIC guard (header regenerated; cbindgen renames updated, incl. PUNKTFUNK_BTN_*/PUNKTFUNK_AXIS_* wire constants). - Protocol: punktfunk/1 — control-plane magic LMN1 → PKF1, nonce salt lmn1 → pkf1. WIRE BREAK: clients must be rebuilt from this revision. - Env knobs: PUNKTFUNK_VIDEO_SOURCE / PUNKTFUNK_COMPOSITOR / PUNKTFUNK_ZEROCOPY / …. - Host config dir: ~/.config/punktfunk (the box's dir was migrated in place — the persistent identity is unchanged, pinned fingerprints stay valid). - Swift package: PunktfunkKit + PunktfunkCore.xcframework + PunktfunkConnection (Sources/PunktfunkClient app + tests renamed with it); build-xcframework.sh updated. - scripts/: 60-punktfunk.rules, punktfunk-host.service; OpenAPI doc regenerated. Also: scripts/headless/run-headless-kde.sh — full headless Plasma bringup. Root cause of "desktop but no apps/settings" over the stream: plasmashell launched without XDG_MENU_PREFIX=plasma-, so the launcher resolved a nonexistent applications.menu and rendered an empty menu. The script sets the complete KDE session env (menu prefix, KDE_FULL_SESSION, session version) and rebuilds ksycoca before starting plasmashell. Gate: 97/97 tests, clippy -D warnings (both feature sets), fmt, C-ABI harness PASS, zero lumen references left outside .git. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> |
