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.
