enricobuehler	333f66b45b	fix(host/serverinfo): don't advertise an empty codec mask when the VAAPI probe finds nothing ... The Phase 3 GPU-aware codec mask (6922e1c) probes VAAPI on any non-NVIDIA host. On a GPU-less box (CI container: no /dev/nvidia* -> `auto` picks VAAPI, but there's no VA display) the probe returns all-false, so the mask was 0 -- the host advertised NO codecs, and the serverinfo unit test failed. Fall back to the static superset when the probe yields nothing (VAAPI wasn't usable, not "the GPU encodes nothing"); quiet ffmpeg's expected "No VA display" error during the probe; and assert the test against codec_mode_support() rather than a hardcoded 65793 so it's deterministic regardless of the build host's GPU.

enricobuehler	6922e1c467	feat(host): VAAPI codec probe + AMD/Intel packaging + neutral logs (Phase 3) ... Polish for AMD/Intel support: - GameStream serverinfo advertises only codecs the GPU can ACTUALLY encode on the VAAPI backend (probed once by opening a tiny encoder per codec). AV1 encode is narrow (Intel Arc/Xe2+, AMD RDNA3+/RDNA4) and an old iGPU may lack HEVC, so a Moonlight client never negotiates a codec the encoder can't open. NVENC/Windows keep the Moonlight-validated static mask. Validated on a Radeon 780M: h264/h265/av1 all probe true -> mask unchanged (65793). - Packaging: Recommends mesa-va-drivers + intel-media-va-driver (deb) / mesa-va-drivers + intel-media-driver (rpm) so the auto-selected VAAPI backend works out of the box on AMD/Intel; NVIDIA boxes can --no-install-recommends. (Fedora note: stock mesa-va-drivers disables HEVC/AV1 -- needs the freeworld variant from RPM Fusion.) - De-NVIDIA-fy the user-facing encoder log/context strings ("open NVENC" -> "open video encoder") now that VAAPI is a first-class backend.

enricobuehler	112a054c35	perf(host): latency hardening for the game-vs-encode GPU contention collapse ... Verified, prioritized analysis in docs/host-latency-plan.md (multi-agent investigation + adversarial verification). Lands the two low-risk tiers: Tier 2B — Linux scheduling hygiene: - boost_thread_priority now nices the capture/encode (-10) and send (-5) threads on Linux (setpriority, best-effort; no-op without CAP_SYS_NICE), and the wrong "gamescope caps the game" doc-comment is corrected. - CUDA context created with CU_CTX_SCHED_BLOCKING_SYNC (frees a core on the shared box instead of busy-spinning on completion). - Copies moved off the default stream onto a per-thread highest-priority CUDA stream (cuStreamCreateWithPriority, graceful NULL-stream fallback) with a per-stream sync that no longer blocks on the other worker thread's in-flight copies. Stream priority is measure-then-keep (NVIDIA Linux may ignore it); never regresses. Tier 3A — Windows session tuning (new session_tuning.rs, raw C-ABI FFI, no-op off Windows): once-per-process 1ms timer + DwmEnableMMCSS + HIGH priority class; per-thread MMCSS "Games" + keep-display-awake. Wired into both the native (boost_thread_priority) and GameStream (stream.rs) paths. We had zero session tuning before (Apollo streaming_will_start parity). Tier 2A (Linux NV12 convert) is specified but intentionally not landed: it is colour-correctness-critical and needs A/B validation on a GPU box with a display (green-screen risk). Builds + clippy + fmt green on Linux. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-18 23:05:57 +00:00
enricobuehler	9c8fa9340c	refactor: drop milestone names + consolidate clients; loss-recovery & rumble fixes ... Two bodies of work in one commit (the rename moved files the fixes also touched). Naming/structure cleanup (pre-launch): - Host modules m3.rs->punktfunk1.rs, m0.rs->spike.rs; CLI m3-host->punktfunk1-host, m0->spike; bare `punktfunk-host` now prints help. Types M3Options/M3Source-> Punktfunk1Options/Punktfunk1Source. - Clients consolidated out of crates/ into clients/: punktfunk-client-rs-> clients/probe (crate punktfunk-probe), client-linux->clients/linux, client-windows->clients/windows, punktfunk-android->clients/android/native (crate punktfunk-client-android; kept [lib] name=punktfunk_android so the JNI contract is unchanged). crates/ now holds only core + host. - Milestone codes M0-M4 purged from code/CLI/CLAUDE.md/README/docs/docs-site, kept only in docs/implementation-plan.md. docs/m2-plan.md-> docs/gamestream-host-plan.md. CI/gradle/flatpak paths updated. Client loss-recovery (video froze and never recovered after a brief drop): - Export punktfunk_connection_frames_dropped through the C ABI (the core already tracked it for the client keyframe-recovery loop; it was never reachable from the ABI clients). Regenerated punktfunk_core.h. - Apple (StreamPump + Stage2Pipeline) and Android (decode.rs) now poll frames_dropped and request a keyframe when it climbs -- the same loss-driven recovery Linux/Windows already had. Under infinite GOP the decoder silently conceals reference-missing frames, so the decode-error trigger rarely fires. Apple rumble robustness (worked then went spotty -- DualSense + Xbox): - Add CHHapticEngine stopped/reset handlers (rebuild on app background / audio interruption / server reset) and drop the permanent `broken` latch on a transient drive failure; latch only when the controller truly has no haptics. - Surface swallowed SDL set_rumble errors on Linux/Windows + diagnostic logging. Verified: cargo build/clippy/fmt --workspace, C-ABI harness, header drift. Not runnable on this box (verify in CI): Gitea workflows, gradle/Android, flatpak, Swift/decky.

enricobuehler	0ce2e37faf	refactor(host/windows): clean up DDA path + add a proper Windows service ... Final cleanup after the DDA-parity work, plus an end-user service to replace the PsExec/VBS/scheduled-task launch chain. Cleanup (behavior-preserving): - sudovda.rs: drop the dead legacy GDI isolate_displays/restore_displays (CCD is the sole isolation path), the always-empty Monitor.isolated field, and the vestigial reassert_isolation + PUNKTFUNK_ISOLATE_DISPLAYS knob; fix stale comments. - dxgi.rs: downgrade leftover debug warns/infos (DuplicateOutput1 retry, FALLBACKS, hook-hits, AcquireNextFrame idle timeout) to debug!; remove the PUNKTFUNK_NO_CURSOR per-frame test knob. Windows service (src/service.rs, `punktfunk-host service`): - SCM supervisor (windows-service crate) that duplicates its LocalSystem token, retargets it to the active console session, and CreateProcessAsUserW's the host there (Sunshine/Apollo model) — relaunching on exit and console session switch, inside a kill-on-close job object so a service crash never orphans the host. - install/uninstall/start/stop/status subcommands: one elevated `service install` registers an auto-start LocalSystem service + firewall rules + a default host.env. - Config moves to %ProgramData%\punktfunk\host.env; config_dir() now resolves to %ProgramData%\punktfunk on Windows (replacing the APPDATA=C:\Users\Public hack), with a PUNKTFUNK_CONFIG_DIR override. Logs land in %ProgramData%\punktfunk\logs\. - merged_env_block (shared with the WGC helper) now also carries RUST_LOG. - docs/windows-service.md + scripts/windows/host.env.example; windows-host.md updated.

enricobuehler	0324719b6e	feat(host/windows): USO batched send for the GameStream video plane ... The GameStream video sender did one send() syscall per packet on Windows (the #[cfg(not(target_os="linux"))] sendmmsg_all fallback), capping throughput at high packet rates. Wire it to UDP Send Offload (the Windows analogue of Linux GSO) so each paced 16-packet burst goes out in one WSASendMsg(UDP_SEND_MSG_SIZE) syscall instead of 16, preserving the microburst pacing. Expose a reusable punktfunk_core::transport::send_uso_all (Windows-only) that reuses the proven native-plane USO primitive (send_one_uso + the uso on/off latch + uso_unsupported), with the same uniform-size guard and ≤512-segment chunking as UdpTransport::send_gso. It returns how many leading packets it sent via USO; the GameStream sendmmsg_all sends any remainder (USO off via PUNKTFUNK_GSO=0, a size-mixed burst, or a frame's short final packet) with per-packet send. On-wire packet boundaries are unchanged. Resolves #4 in docs/apollo-comparison.md. Linux build unaffected; punktfunk-core type-checks for x86_64-pc-windows-msvc. Host Windows compile deferred to CI / dev box. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>	2026-06-16 10:21:33 +00:00
enricobuehler	bbabc04bca	feat(hdr): Windows HDR10 + 10-bit end-to-end, negotiated; non-blocking capture recovery ... Adds true HDR (BT.2020 PQ) and 10-bit (HEVC Main10) streaming, negotiated so an 8-bit/SDR client is never sent a stream it can't decode, plus a robust fix for the capture losing the stream across a secure-desktop transition. Protocol (punktfunk-core/quic.rs): - Hello gains `video_caps` (VIDEO_CAP_10BIT / VIDEO_CAP_HDR), Welcome gains `bit_depth`, both as optional trailing bytes (back-compat). client-rs advertises 10-bit via PUNKTFUNK_CLIENT_10BIT; the connector advertises 0 for now (in-band detection drives the native clients). Regenerated punktfunk_core.h. Windows host: - 10-bit Main10: host enables it only when the client advertised VIDEO_CAP_10BIT AND PUNKTFUNK_10BIT is set; threaded through open_video → NVENC (profile Main10, pixelBitDepthMinus8). - HDR: when the captured desktop is scRGB FP16 (R16G16B16A16_FLOAT, HDR on), copy it to an FP16 surface, composite the cursor there, convert scRGB → BT.2020 PQ 10-bit (R10G10B10A2) via a shader, and encode HEVC Main10 with the BT.2020/PQ colour VUI (ABGR10 input). Fixes the freeze + cursor-trail that came from feeding FP16 into the BGRA path. Reacts dynamically to the HDR toggle. - Capture recovery: rebuild is now a single NON-BLOCKING attempt, throttled to ~4×/s, repeating the last good frame between attempts (format-tagged last_present). During a secure-desktop dwell SudoVDA's output is gone; the old blocking 12 s retry starved the send loop for seconds so the client timed out and disconnected — now the session stays fed (frozen) until the desktop returns. Also seeds a black frame on recovery. Apple client (PunktfunkKit): - Detects HDR in-band from the stream VUI (PQ transfer function), decodes to 10-bit P010, and presents via an rgba16Float + BT.2020 PQ CAMetalLayer with EDR; SDR path unchanged. Switches automatically on a mid-session HDR toggle. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-15 20:28:52 +00:00
enricobuehler	7654b20b2a	fix(host/windows): NVENC capture on real GPU + HOME-less config dir ... Validated live on an RTX 4090 (Windows 11) host streaming to the Rust reference client over the LAN: SudoVDA virtual display → DXGI Desktop Duplication (D3D11 zero-copy) → NVENC HEVC → punktfunk/1. 720p60 and 1080p60 both clean (181 / 177 frames, 0 mismatched, p50 1.6 / 3.45 ms cross-machine), coexisting with Apollo. Two real-hardware bugs the GPU-less VM couldn't surface: - DXGI capturer: the SudoVDA virtual monitor's DXGI output is enumerated under the GPU that *renders* it (the 4090, LUID 0x15df6), NOT under the SudoVDA "adapter" LUID SudoVDA reports (0x23276). Restricting the output search to that LUID found nothing → "adapter has no output named \\.\DISPLAYn". Now search ALL adapters for the GDI name, bind the D3D11 device to whichever adapter exposes it (NVENC then shares that device), with a settle-retry (the output appears a beat after display creation) and topology logging. - native_pairing / apps: keyed config paths off raw $HOME, which a Windows service/scheduled-task context doesn't set → "HOME unset" hard-fail at m3-host startup. Route both through gamestream::config_dir(), which falls back to %APPDATA% on Windows (cert/paired/apps now under AppData\Roaming). clippy -D warnings + build green on x86_64-pc-windows-msvc (default and --features nvenc) and Linux (78/78 tests).

enricobuehler	b2e5878711	feat(host/mgmt): HTTPS + token auth by default (no loopback no-auth fallback) ... The mgmt API already always serves HTTPS (the host identity cert), but on a loopback bind with no token it ran unauthenticated — any local process could drive it. Make auth required ALWAYS: - new mgmt_token::load_or_generate(): token precedence is --mgmt-token > env PUNKTFUNK_MGMT_TOKEN > persisted ~/.config/punktfunk/mgmt-token > freshly generated 32-byte hex, persisted 0600 in KEY=VALUE form (so the bundled web console can source it directly as a systemd EnvironmentFile — one source of truth). config_dir() made pub(crate). - parse_serve() resolves the token via load_or_generate() when unset, so a bare `serve` Just Works with auth on and no operator step. - mgmt::run() drops the loopback no-token exemption and requires a token; require_auth()'s unauthenticated fallback now returns 401. The paired-cert (mTLS) branch is unchanged — Apple client + library auth unaffected. - web /api proxy: 503 (legible) instead of forwarding an empty bearer. - tests: test_app/test_app_native default a token, send() auto-attaches the bearer; blank-token test asserts the new "no token" refusal. 80 pass. - docs: mgmt module doc + host.env.example reflect always-on auth + auto-gen. Compiles, clippy/fmt clean, openapi no drift. Part B (bundle the web console into apt, auto-wired to this token) follows.

enricobuehler	66f579461f	feat(host/windows): GameStream (Moonlight) audio on Windows — stereo ... `serve` gave Moonlight clients no audio on Windows: the GameStream audio stream thread was Linux-only (a non-Linux stub errored). Widen the stereo path to Windows — the encode/RTP/AES-CBC/hand-rolled-RS(4,2)-FEC logic is platform-neutral and already live-validated byte-identical on Linux, and it now runs over the WASAPI capturer + the (already cross-platform) `opus` crate. The cfg gates go from `linux` to `any(linux, windows)`; only the surround path stays Linux-only because its libopus *multistream* encoder needs `audiopus_sys` (a Linux dep) — on Windows a surround request fails cleanly with a "use stereo" error. Linux stays byte-identical (the `SessionEncoder::Surround` variant and its match arm keep `#[cfg(linux)]`, so Linux compiles exactly as before). Verified: clippy -D warnings + host test suite green on both x86_64-pc-windows-msvc (73/73) and Linux (78/78).

enricobuehler	04b76ebfc7	feat(host/windows): run serve/m3-host on Windows (config paths + compositor) ... The punktfunk/1 control plane already compiled on Windows; these wire the last gaps so the host actually runs: config_dir falls back to %APPDATA% (HOME\.config when set), paired_path uses it, hostname from COMPUTERNAME, and resolve_compositor short-circuits the Linux session-detection on Windows (SudoVDA is the single backend; vdisplay::open ignores the compositor arg). Validated live on the VM: m3-host creates its identity, binds the QUIC endpoint (fingerprint logged), advertises mDNS (_punktfunk._udp, host from COMPUTERNAME), and accepts sessions. GPU-less validations green: m0 synthetic->openh264->core FEC loopback (120/120, 0 mismatches) and the m3 c_abi_connection_roundtrip control-plane test. Full session capture (SudoVDA->DXGI) + NVENC remain GPU-gated. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-15 01:15:51 +00:00
enricobuehler	b4a85a8610	feat(host/mgmt): mTLS auth — a paired client's cert authorizes the REST API ... Phase 1 of moving the library off a manual mgmt token: the management API now serves over HTTPS with the host's persistent identity (the cert clients already pin) and OPTIONAL client-cert auth. A request is authorized if EITHER the peer presented a client certificate whose SHA-256 is in the punktfunk/1 paired store (the same trust the QUIC data plane uses — so a paired native client needs no token), OR it carries the bearer token (the web console / admin). `/health` stays open. axum-server can't surface the peer cert to a handler, so `serve_https` runs the rustls handshake itself (tokio-rustls), reads the verified peer certificate, and serves the axum Router over hyper with the fingerprint attached to each request; `require_auth` checks it against `NativePairing::is_paired`. The verifier reuses the GameStream AcceptAnyClientCert, parameterized to make client auth optional (a browser with no cert still completes the handshake and falls back to the token). Validated live: paired cert → 200, unpaired cert / no creds / bad token → 401, bearer → 200, /health open. (Note: the API is now HTTPS with a self-signed cert — a browser shows a one-time trust prompt; native clients pin by fingerprint.) Next: Apple client presents its identity over mTLS (drops the token field); embed the web console; enable HTTPS mgmt by default.

enricobuehler	9a6058cd20	feat(host): §8a — require native pairing by default (serve --open to disable) ... 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.

enricobuehler	19666ba57e	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.

enricobuehler	6575dddac7	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.

enricobuehler	ff4fe197be	fix(punktfunk/1): adversarial-review fixes — SPAKE2 pairing, renegotiation hardening, +more ... 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.

enricobuehler	3cc3c02b42	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).

enricobuehler	bfd64ce871	rename: lumen → punktfunk, everywhere ... 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.
