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(apple): adapt the macOS client to ABI v2 — client identity + SPAKE2 PIN pairing
ci / rust (push) Has been cancelled
The pairing/renegotiation batch bumped the punktfunk/1 ABI to v2 and the host now hard-rejects v1 Hellos (m3.rs), so streaming from the Mac was dead until the bundled PunktfunkCore.xcframework is rebuilt — it is gitignored, so that is a per-checkout step: bash scripts/build-xcframework.sh. The Swift wrapper itself was already adapted upstream; this lands the app on top of it. - ClientIdentityStore: persistent client identity in the login Keychain, presented on every connect so paired hosts recognize this Mac. Keychain access failure throws instead of regenerating (a fresh identity would silently un-pair this Mac from every --require-pairing host); a lost first-run race resolves toward the stored identity; pairing uses the strict loadForPairing() so a memory-only identity can't strand a ceremony. - PairSheet: the SPAKE2 PIN ceremony, reachable from a host card's context menu and from the trust prompt's "Pair with PIN instead…" (which drops the live session first — the host's accept loop is sequential). Success pins the verified fingerprint and connects; an in-flight ceremony self-discards when the sheet is dismissed, so a late success can't pin + auto-connect behind the user's back. Wrong PIN and Keychain failures get distinct, actionable error text. - Tests: identity unit tests; the full pairing ceremony + --require-pairing gate on loopback (test-loopback.sh arms a second host, parses its PIN from the log, and gives both hosts throwaway config homes — no more writes to the real ~/.config/punktfunk); remote pairing + pinned stream over the LAN (PUNKTFUNK_REMOTE_PIN, _PORT). Validated live against the box: SPAKE2 ceremony with the host's arming PIN → verified fingerprint → pinned + identified 720p60 session (host persisted the client identity); first light 60/60 AUs decoded to pixels; vkcube on glass through the app. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> |

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).

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> |

docs: box setup complete — Mutter + system gamescope + gamepads all live-validated
ci / rust (push) Has been cancelled
- Mutter backend validated on headless GNOME Shell 50.1: RecordVirtual virtual monitor at the client's mode, 360/360 frames @1080p60, p50 1.28 ms, tiled-dmabuf zero-copy. All three VirtualDisplay backends (KWin/gamescope/Mutter) are now proven live. - gamescope 3.16.22 system install validated (720/720 @720p120 via /usr/local/bin, the PATH override is retired from the docs). - Gamepads validated live over lumen/1: client datagrams -> uinput "Microsoft X-Box 360 pad" created (event9/js1), destroyed with the session (udev rule + input group active).

feat: M4 stage 1 — the SwiftUI client is real: compiles, tested, first light on glass
ci / rust (push) Has been cancelled
The clients/apple scaffold is now a working macOS client, validated live against this repo's host across the LAN: gamescope virtual output → NVENC HEVC → lumen/1 (GF(2¹⁶) FEC + AES-GCM over UDP, QUIC control) → VideoToolbox → AVSampleBufferDisplayLayer at 720p60, mouse/keyboard flowing back as QUIC datagrams into the host's gamescope EIS injector (~3.7k events injected in one session). LumenKit: - LumenConnection: the predicted cbindgen compile fixes (C17 header spells the typedefs as integers while the enum constants import as a distinct Swift type — bridge by rawValue); close() is now safe from any thread (a close flag + pumpLock held across the blocking poll enforce the C contract "never close with a next_au in flight"; flag prevents lock-starvation by back-to-back polls). - StreamView: per-pump cancellation token (reconnects can't double-pump), flush + re-gate on the next in-band parameter sets when the layer fails, no stale enqueue after restart. - InputCapture: fractional-delta accumulation (sub-pixel motion isn't truncated away), pressed-state tracking with release-all on focus loss and stop() (nothing sticks down host-side), global-singleton ownership guard (GC has one handler slot per process), X1/X2 buttons, horizontal scroll, full keypad/CapsLock/ISO-102nd/PrintScreen/Menu VKs. - LumenClient app shell (swift run LumenClient): connect form, fps/Mb-s HUD, LUMEN_AUTOCONNECT/LUMEN_MODE for scripted first-light runs. - Tests: Annex-B byte-level units; real-codec round trip (VTCompressionSession-encoded HEVC rebuilt as the host's wire shape → AnnexB → VTDecompressionSession → pixels); test-loopback.sh (Swift client vs a real local m3-host over loopback — the Swift twin of c_abi_connection_roundtrip); RemoteFirstLightTests (full pipeline over the LAN). Host/build fixes that fell out: - The workspace builds on non-Linux again: gamestream audio (opus) and sendmmsg batching are now platform-gated with stubs/fallback, per the crate's "compiles everywhere" rule. - Horizontal scroll was inverted end-to-end: the injectors negated BOTH axes onto the ei/wl axes, but GameStream's horizontal convention is positive = right (moonlight-qt/Sunshine pass it through unnegated) — only vertical flips now. This also un-inverts real Moonlight clients. - AnnexB drops all zeros preceding a start code (trailing_zero_8bits padding), ffmpeg's policy, instead of leaking them into the preceding NAL. - build-xcframework.sh: deployment targets pinned to the package floor + an otool guard — cargo does not fingerprint MACOSX_DEPLOYMENT_TARGET, so warm caches can silently ship too-new minos objects. Adversarially reviewed (5-dimension multi-agent pass, every finding refutation-verified): 14 confirmed findings, all fixed above; the send-while-polling core-contract gap flagged here is closed by the lumen/1 session-planes work (&self pulls + per-plane borrow slots).

feat: M3 — full lumen/1 session planes: audio, gamepads+rumble, pinned trust, persistent listener
ci / rust (push) Has been cancelled
m3-host is now a real host, not a one-shot demo. Everything validated live on this box (two back-to-back sessions, pinned + TOFU, ~200 audio pkts/s, p50 0.84 ms at 720p60). lumen-core: - quic.rs: QUIC-datagram side planes demuxed by first byte — Opus audio 0xC9 ([magic][u32 seq][u64 pts_ns][opus], host→client) and rumble 0xCA ([magic][pad][low][high]). - Trust: endpoint::server_with_identity (persistent PEM identity) and endpoint::client_pinned — SHA-256 cert-fingerprint pinning with TOFU (observed fingerprint reported back for persisting). The verifier checks the TLS 1.3 CertificateVerify signature for real (an MITM replaying the host's public cert without its key is rejected; cert pinning alone would not prove key possession). - client.rs: NativeClient gains pin + host_fingerprint, audio/rumble receivers (next_audio / next_rumble); pull methods take &self so the C ABI's per-plane threads never alias a &mut (per-plane mutexed borrow slots in abi.rs). - abi.rs: lumen_connect(pin_sha256, observed_sha256_out) + lumen_connection_next_audio / next_rumble. input.rs: documented gamepad wire contract (GameStream buttonFlags bits, XInput axis conventions, +y = up) — exported as LUMEN_BTN_*/LUMEN_AXIS_* (bare BTN_* collides with <linux/input-event-codes.h> at different values). lumen-host (m3): - Persistent accept loop: sessions back to back on one endpoint (--max-sessions, 0 = forever); per-session failures log and the loop keeps serving; 10 s handshake deadline so a silent client can't wedge the sequential accept queue; teardown on every exit path (stop flag → conn.close → join audio+input threads). - Audio plane: desktop PipeWire capture → Opus 48 kHz stereo 5 ms CBR → datagrams; ONE capturer reused across sessions via an AudioCapSlot (PipeWire streams have no cheap teardown — per-session opens would leak a thread + core connection + live node each). - Gamepad routing: incremental GamepadButton/GamepadAxis datagrams accumulate into per-pad state feeding the uinput xpad manager; force feedback returns as rumble datagrams, with current state re-sent every 500 ms (idempotent-state healing for the lossy channel). QUIC endpoint serves the persistent ~/.config/lumen identity and logs the pinnable fingerprint. lumen-client-rs: --pin (malformed values abort — never silently downgrade to TOFU), TOFU fingerprint logging, audio/rumble datagram counters, gamepad events in --input-test. clients/apple: scaffold synced — pinSHA256/hostFingerprint (wrong-size pin throws, fail-closed), nextAudio/nextRumble, gamepad event constructors; README handoff updated (persistent listener, audio decode notes, trust UX). Adversarially reviewed (5-dimension multi-agent pass over the diff, 2-skeptic verification): fixed the MITM signature-check gap, a Y-axis contract inversion, header macro collisions, ABI aliasing UB, the PipeWire per-session leak, the missing handshake deadline, fail-open pin parsing, and teardown-on-error paths.

feat: M4 groundwork — lumen/1 client connector in the C ABI + SwiftUI client scaffold
ci / rust (push) Has been cancelled
The shared-core architecture pays off: platform clients now link ONE Rust library that does the entire lumen/1 protocol, and only add decode/present/input on top. lumen-core: - client.rs (quic feature): NativeClient — QUIC handshake + UDP data plane + input datagrams on internal threads; embedder surface = connect / next_frame / send_input. - abi.rs: lumen_connect / lumen_connection_next_au (borrow-until-next-call, matching lumen_client_poll_frame semantics) / lumen_connection_send_input / lumen_connection_mode / lumen_connection_close. Guarded in the generated header by LUMEN_FEATURE_QUIC (cbindgen [defines] mapping), so the checked-in header is stable across feature sets. - error.rs: append-only LumenStatus additions Timeout (-9) and Closed (-10). - TESTED end-to-end through the C ABI: in-process lumen/1 host, lumen_connect pulls 25 byte-verified frames, sends input, closes (m3.rs::c_abi_connection_roundtrip). Apple client (clients/apple — SCAFFOLD, written on Linux, first Xcode build pending): - scripts/build-xcframework.sh: cargo per Apple target → universal staticlib + header (LUMEN_FEATURE_QUIC pre-defined) + modulemap → LumenCore.xcframework. - Package.swift (LumenKit) + Swift sources: LumenConnection (ABI wrapper), AnnexB (in-band VPS/SPS/PPS → CMVideoFormatDescription, Annex-B → AVCC CMSampleBuffers with DisplayImmediately), StreamView (SwiftUI over AVSampleBufferDisplayLayer — stage-1 presenter that hardware-decodes compressed HEVC itself), InputCapture (GCMouse raw deltas + GCKeyboard HID→VK). - README.md is the full handoff for the next (Mac-side) agent: build steps, ABI contract, first-light test recipe against the Linux host, stage-2 (VT+Metal pacing) plan, and the known host-side gaps (single-session m3-host, no lumen/1 audio yet, gamepad kinds not yet routed in m3's injector, seed-stage trust).

docs: bring CLAUDE.md up to date (M2 working, M3 validated, what's-left roadmap)
ci / rust (push) Has been cancelled
Status: M2 streams to a stock Moonlight client at native client resolution/refresh across KWin/gamescope (Mutter pending validation) with zero-copy + split-encode + gamepads; M3 lumen/1 validated (QUIC control plane, GF(2^16)+AES-GCM, datagram input, p50 0.83ms pipeline latency). What's-left: M4 client decode/present, NVENC-SDK sub-frame pipelining, lumen/1 trust model, M2 polish, native clients, plus this box's pending one-time setup.

fix: M2 — harden the management API after adversarial review
ci / rust (push) Has been cancelled
Five confirmed findings from a 46-agent review panel:
- Empty --mgmt-token no longer satisfies the non-loopback token gate
(critical: 'Bearer ' with an empty token authenticated; parse_serve now
bails on blank tokens and mgmt::run treats blank as none)
- axum's built-in body rejections (400/415/422) now wear the documented
ApiError envelope via an ApiJson extractor, and the spec documents them
- GET /health carries security([{}]) in the spec, matching the server's
auth exemption
- unpairClient's description no longer claims revocation the TLS layer
doesn't enforce yet (gamestream/tls.rs accepts any cert — known gap)
- CLAUDE.md/README.md no longer reference the deleted web.rs

feat: M2 — management REST API with OpenAPI doc (control-pane groundwork)
A versioned control-plane REST API (/api/v1) on its own port (default 127.0.0.1:47990) serving host info, runtime status, paired-client management, the pairing PIN flow, and session control (stop / force-IDR). The OpenAPI 3.1 document is generated from the handlers by utoipa, served live at /api/v1/openapi.json (+ Scalar docs at /api/docs), printable via `lumen-host openapi`, and checked in at docs/api/openapi.json for client codegen — a test fails if it drifts, mirroring the cbindgen header rule. Auth: optional bearer token (--mgmt-token / LUMEN_MGMT_TOKEN), enforced on everything but /health, and mandatory for non-loopback binds. PinGate gains a waiter count so the API can report pin_pending; logs moved to stderr so stdout stays machine-readable. Supersedes the web.rs stub.

docs: VM handoff — CLAUDE.md, Ubuntu bootstrap, headless-Sway setup for M0
Prepares the move to the NVIDIA-GPU Ubuntu VM where M0/M2 run (macOS can't drive the Wayland/GPU stack). The repo carries the context, since Claude Code sessions are machine-local and don't transfer. - CLAUDE.md: project state + design invariants + don't-regress security notes. Auto-loads every session, so a fresh session on the VM continues from here. - scripts/bootstrap-ubuntu.sh: verifies the (already-installed) NVIDIA/NVENC stack, installs rustup + PipeWire/portal/wlroots/Sway + DRM/EGL/GBM/VA dev deps; GATES the FFmpeg -dev headers so apt can't clobber a custom NVENC build; checks nvidia-drm.modeset. - scripts/headless/: headless-Sway + xdg-desktop-portal-wlr config templates, the NVIDIA-wlroots env workarounds, run-headless-sway.sh, and a wf-recorder->hevc_nvenc capture smoke test (proves capture->NVENC with no Rust). - docs/linux-setup.md: M0 walkthrough + verified gotchas (modeset, headless backend, vGPU NVENC licensing, dmabuf->NVENC CPU-copy fallback, FFmpeg-dev gate, crate versions). Ubuntu 24.04 package names/versions verified against the live archive; scripts pass shellcheck and `bash -n`. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> |
