enricobuehler	38cce754bd	docs: mark session-aware follow-ups #2 (switch input) + #3 (vout primary) resolved ... Both landed in 3363576 and validated live on the Bazzite F44 box: a Gaming→Desktop mid-stream switch shows `settled desktop portal env … compositor=kwin` → `portal granted devices` → `device RESUMED` (input lands, no reconnect), and `KWin: streamed output set as the sole desktop also_disabled=["HDMI-A-1"]` (panels on the streamed screen). Remaining: #1 (F44 gamescope teardown GPU leak) + the lower-priority polish. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-15 07:12:29 +00:00
enricobuehler	336357643c	feat(host): KWin virtual output primary + settle portal env on switch ... Two parked follow-ups from the session-aware host work: #3 — KWin/Mutter virtual output not set primary. The auto-detected desktop path *is* "stream this desktop", but the per-session virtual output wasn't promoted to primary, so KDE/GNOME panels + windows stayed on an unstreamed real output and the streamed screen showed only wallpaper. apply_session_env now defaults PUNKTFUNK_KWIN_VIRTUAL_PRIMARY / PUNKTFUNK_MUTTER_VIRTUAL_PRIMARY on for the auto path (explicit config still wins), so the streamed output becomes the sole desktop. #2 — input flaky after a mid-stream Gaming->Desktop switch. The xdg portal (D-Bus-activated) and the systemd --user env still pointed at the old session, so the host's RemoteDesktop portal opened against a half-stale env: it accepted events but they didn't reach the compositor until a reconnect. New vdisplay::settle_desktop_portal() pushes the live session env into the systemd/D-Bus activation environment and (for KWin) restarts the portal so it re-reads it, mirroring a fresh desktop login (and the existing wlroots portal restart). Called from the mid-stream switch rebuild slot before the injector reopens. GNOME uses Mutter's direct EIS, so it only gets the env push. Compiles, clippy/fmt clean, 78 host tests pass. Live validation on the Bazzite box next. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-15 06:49:53 +00:00

enricobuehler	5cf7b561b5	docs(windows-host): gamepad done; audio/rumble/GPU-validation remaining ... Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-15 01:48:23 +00:00
enricobuehler	8cba886c17	feat(host/windows): ViGEm virtual gamepad backend ... Windows GamepadManager via vigem-client (ViGEmBus) — the uinput-xpad analogue: one virtual Xbox 360 controller per client pad index, created lazily on first State. GameStream/Moonlight already uses the XInput conventions (low-16 button bits, sticks -32768..32767 +Y up, triggers 0..255), so the GamepadFrame->XGamepad mapping is 1:1. Replaces the non-Linux GamepadManager stub (same new/handle/pump_rumble API the m3 PadBackend drives, so no m3 change). Graceful when ViGEmBus is absent (gamepad disabled, session continues). Compiles clean on Windows + Linux; live-test needs the ViGEmBus driver + a physical pad. Rumble back-channel is a TODO (ViGEm notification API).

enricobuehler	69ba6ec45d	feat(host/windows): NVENC D3D11 hardware encoder (--features nvenc) ... Zero-copy capture->encode on the GPU via the raw NVENC API (nvidia_video_codec_sdk sys + ENCODE_API; the safe wrapper is CUDA-only). Opens an NV_ENC_DEVICE_TYPE_DIRECTX session on the SAME ID3D11Device as the DXGI capturer (carried on the new FramePayload::D3d11), registers a pool of BGRA textures once, CopyResources each captured texture in and encode_picture; CBR/ULL, infinite GOP, P-only, forced-IDR for RFI. The DXGI capturer gains a D3D11 zero-copy output (selected, like the encoder, by PUNKTFUNK_ENCODER=nvenc) so capture+encode share textures. OFF by default (the nvenc feature pulls the NVENC SDK + cudarc): the default Windows host links without it (openh264 path). cudarc builds toolkit-less via the SDK ci-check feature (dynamic-loading). At link time --features nvenc needs nvencodeapi.lib (NVENC SDK, or an import lib generated from the driver's nvEncodeAPI64.dll) on PUNKTFUNK_NVENC_LIB_DIR. Both default and --features nvenc builds validated to compile+link GPU-less on the VM (import lib generated from the driver DLL). Runtime needs a real NVIDIA GPU.

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	9c2499fd45	feat(host/windows): DXGI Desktop Duplication capture backend ... Windows Capturer via DXGI Desktop Duplication: create a D3D11 device on the SudoVDA adapter (by LUID), find the matching output (by GDI name), DuplicateOutput, and per AcquireNextFrame copy the desktop into a CPU-readable staging texture -> tightly-packed BGRA (FramePayload::Cpu, feeds the openh264 software encoder GPU-lessly). Handles WAIT_TIMEOUT (reuse last frame) and ACCESS_LOST (re-duplicate). Adds FramePayload::D3d11(D3d11Frame) for the future NVENC zero-copy path, and a VirtualOutput.win_capture identity (adapter LUID + GDI name) carried out of the SudoVDA backend. Pure helpers (pack_luid/gdi_name_matches/depad_bgra) unit-tested on the VM; the live duplication path needs a real GPU + an activated SudoVDA monitor. Compiles clean on Windows + Linux.

enricobuehler	45e5157091	feat(host/windows): WASAPI loopback audio capture ... Windows AudioCapturer via the wasapi crate (0.23): loopback the default render endpoint (Render device + Direction::Capture + shared mode => STREAMFLAGS_LOOPBACK) at 48 kHz stereo f32 with autoconvert, feeding the existing Opus path with no resampling. Dedicated COM-MTA thread owns the !Send WASAPI objects; interleaved f32 chunks leave over a bounded lossy channel; RAII Drop stops + joins. Bring-up handshake reports a missing endpoint as Err so a session continues without audio. open_audio_capture Windows factory arm + module. Init chain validated live on the VM (open succeeds; next_chunk waits on a silent system). Virtual mic deferred (no Windows virtual-audio endpoint). m3 audio_thread wiring + opus hoist land with the integration task.

enricobuehler	cbbeaa5c29	feat(host/windows): openh264 software H.264 encoder (GPU-less path) ... Windows Encoder impl via the openh264 crate (statically-bundled, BSD-2): low-latency screen-content config (Baseline/no-B-frames, bitrate RC, BT.709 limited, near-infinite GOP + forced-IDR recovery via request_keyframe), packed CPU pixels (BGRx/BGRA/RGB/RGBA/RGBx/BGR) -> I420 -> AnnexB with in-band SPS/PPS each IDR. Synchronous: submit encodes immediately, poll hands back the one AU, flush is a no-op. Windows open_video factory selects it (PUNKTFUNK_ENCODER=software|nvenc|auto; NVENC arm lands later), H.264-only with a clear error otherwise, SW bitrate ceiling. Unit-tested live on the VM: synthetic BGRx -> AnnexB IDR + SPS NAL. Unblocks the GPU-less capture->encode->FEC->send pipeline. Compiles clean on Windows + Linux.

enricobuehler	cce2eb60f6	feat(host/windows): SendInput input-injection backend ... Windows InputInjector via SendInput (Win32 KeyboardAndMouse), mirroring the wlroots backend: absolute mouse (MOUSEEVENTF_VIRTUALDESK normalized to the virtual desktop), relative mouse, scancode keyboard (MapVirtualKeyExW + extended-key flagging), scroll (no sign flip — Windows wheel matches GameStream), buttons. Client already sends Windows VK codes (no keycode table). Reattaches the thread to the input desktop (OpenInputDesktop/SetThreadDesktop) to survive UAC/lock switches. New Backend::SendInput, the Windows auto-default in default_backend(), open() arm, windows-crate features. Compiles clean on Windows + Linux. Live injection validates with the in-session host run (SendInput is desktop-isolated from an SSH network logon).

enricobuehler	26741feada	feat(host/windows): SudoVDA virtual-display backend (control path) ... Windows VirtualDisplay backend driving SudoVDA (the Apollo IDD) via its DeviceIoControl IOCTL protocol: open by interface GUID, ADD at the client's exact WxH@Hz (mode baked into the IOCTL, no EDID seeding), mandatory watchdog ping thread, QueryDisplayConfig name resolution, RAII Drop -> REMOVE. Wired behind the existing VirtualDisplay trait (open()/probe() Windows arms). Validated live on the GPU-less VM (standalone + via the trait, env-gated test): version 0.2.1, ADD 1920x1080@60 -> target, watchdog hold, REMOVE. Monitor activation into a WDDM path (-> capturable \\.\DisplayN) needs a real GPU and is deferred with capture/NVENC. docs/windows-host.md updated.

enricobuehler	de7b8ac282	feat(android): video decode pipeline — NDK AMediaCodec → SurfaceView ... M4 Android stage 1 (video). Pull HEVC access units from the connector and render them to the SurfaceView entirely in Rust (NDK AMediaCodec → ANativeWindow) — no per-frame JNI, honoring the native-thread hot-path invariant. - crates/punktfunk-android: decode.rs (one-in/one-out AMediaCodec loop; in-band VPS/SPS/PPS so no out-of-band csd; dims from NativeClient::mode). SessionHandle now holds an Arc<NativeClient> + the decode thread; nativeStartVideo/nativeStopVideo. - clients/android: connect screen (host/port) + full-screen SurfaceView stream screen — surfaceCreated -> nativeStartVideo, leaving -> stop + close. Verified live (Android emulator -> m3-host on the LAN box, ABI v2): QUIC handshake, 8-round clock-skew sync, HEVC decoder configured at 1280x720, and the data plane delivered + fed all 299 access units (the punktfunk/1 NAT hole-punch worked through the emulator's SLIRP). Real-pixel render is pending a non-synthetic source: `m3-host --source synthetic` emits dummy transport payloads (not HEVC), so the decoder correctly produces nothing; `--source virtual` (a compositor on the host) is needed to verify decode-to-screen.

enricobuehler	9775794ba5	docs: known limitations + follow-ups for the session-aware host ... Capture the deliberately-parked items after live-validating the session-aware backend selector on the Bazzite F44 box (Desktop KDE + Gaming both at the client's resolution, warm reuse, Feature B mid-stream switch both directions). Top follow-ups: (1) F44 gamescope teardown corrupts the GPU context (try SIGKILL teardown, else keep the managed session warm); (2) mid-stream-switch input is flaky until a reconnect (portal opens before the systemd/D-Bus activation env settles — fix: import-environment on switch); (3) the KWin virtual output isn't set primary. Plus polish: input-loss window on switch, the recovered NVENC invalid-param log, the 4090 HEVC ~800Mbps cap, restore-guard/keep-warm interaction, and promoting Feature B from opt-in to default.

enricobuehler	8534959021	fix(ci/flatpak): cargo-sources generator needs python3-tomlkit, not toml ... flatpak-cargo-generator.py (master) imports `tomlkit` + `aiohttp`; the workflow installed `python3-toml`, so the "Generate offline cargo sources" step would fail with ModuleNotFoundError. Install python3-tomlkit instead, and correct the same note in build-flatpak.sh. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-15 01:47:09 +02:00
enricobuehler	8956bc14de	feat(packaging/flatpak,decky): Steam Deck client flatpak + plugin deploy + CI ... Ship the punktfunk Linux client to the Steam Deck as a Flatpak — the only viable SteamOS install path, since /usr is read-only and lacks libadwaita/SDL3 — and publish both it and the Decky plugin through Gitea. Built and validated live on a Steam Deck (SteamOS 3.7): bundle installs user-scope, all libs resolve, libavcodec resolves to the codecs-extra HEVC build, devices=all for DualSense hidraw. packaging/flatpak (new): - io.unom.Punktfunk.yml on GNOME 50 / freedesktop-sdk 25.08. rust-stable//25.08 (rustc 1.96 — the GTK4 chain needs >=1.92; the EOL GNOME-48/24.08 rust-stable at 1.89 could not build it) + llvm20 (libclang for bindgen in ffmpeg-sys-next/sdl3-sys). HEVC libavcodec comes from the runtime's auto codecs-extra extension point (no app-side codec declaration). Bundled SDL3 3.4.10 (matches sdl3-sys 0.6.6+SDL-3.4.10). finish-args: wayland/fallback-x11, --device=all (GPU/VAAPI + evdev + hidraw — flatpak cannot bind /dev/hidrawN char devices via --filesystem), pulseaudio, network, ~/.config/punktfunk. - metainfo.xml, desktop, square SVG icon, build-flatpak.sh (offline cargo-sources; on-Deck org.flatpak.Builder or CI), README. clients/decky: - add LICENSE (MIT), fix package.json license (BSD-3-Clause -> Apache-2.0 OR MIT), add scripts/{package.sh,deploy.sh} (the plugins dir is root-owned: stage to /tmp, sudo install, restart plugin_loader), align the launcher fallback to the real flatpak app id io.unom.Punktfunk, rewrite the install section. .gitea/workflows: - flatpak.yml: privileged Fedora container builds the bundle and publishes to the Gitea generic registry (+ release attachment on tags). - decky.yml: pnpm build -> store-layout zip -> registry (stable latest/ URL for Decky "install from URL"). docs: packaging/README + packaging/flatpak/README.

enricobuehler	79217eb93d	feat(android): scaffold the native Android client (Rust-heavy JNI bridge) ... Rust-heavy client model (like punktfunk-client-linux): a new cdylib crate crates/punktfunk-android links punktfunk-core and exposes the JNI seam; Kotlin (clients/android) owns only the Android-framework surface. Kotlin can't import the C header the way Swift can, so the bridge is written in Rust to reuse the Linux client's orchestration rather than re-port it. - crates/punktfunk-android: JNI bridge — abiVersion/coreVersion native-link proof + session connect/close handle; plane pumps stubbed for M4 stage 1. - clients/android: Gradle project — :app (Compose) + :kit (Android library with a cargo-ndk Exec task -> jniLibs). AGP 9.2 / Gradle 9.4.1 / Kotlin 2.3.21 / Compose BOM 2026.05.01 / compileSdk 37 / targetSdk 36 / minSdk 31, shipping arm64-v8a + x86_64. Phone + TV (leanback) installable. README rewritten. - .gitea/workflows/android.yml: CI mirroring apple.yml on a Linux runner. - punktfunk-core: switch rcgen to the ring backend so the whole quic tree is aws-lc-free (smaller client .so, cmake-free cross-compile; a win for all targets). Validated on this box: :app:assembleDebug -> APK with both ABIs; emulator first-light renders the bridge linked (core ABI v2) with logcat confirmation; clippy -D warnings + cargo fmt clean; core tests green on the ring backend.

enricobuehler	c9e90d4a59	docs(windows-host): host-first plan + SudoVDA protocol + no-GPU strategy ... Rewrite the scoping doc into a concrete implementation plan: locked decisions (host-first, SudoVDA virtual display, pure-Rust windows-rs+Reactor client linking core directly, FFmpeg/D3D11VA decode), the SudoVDA IOCTL control protocol, the no-GPU dev strategy, the Windows-specific structural issues (interactive session, clock epoch, no IDD audio), and the phased plan. Step 0 (compile on MSVC) marked done. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-14 23:30:24 +00:00
enricobuehler	5fddaac6af	fix(host): compile punktfunk-host on windows (x86_64-pc-windows-msvc) ... Gate the Linux-only bits so the host crate builds on MSVC (it already built on Linux + macOS): drm_sync/dmabuf_fence use DRM ioctls + libc (a linux-only target dep) and have no non-Linux callers; VirtualOutput.remote_fd is a PipeWire concept. The full dep tree (aws-lc-rs, quinn, rusty_enet, axum) builds clean on MSVC and the binary runs (openapi emits the spec) — only these 3 cfg-gates were needed. First step of the Windows host port (docs/windows-host.md). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-14 23:30:24 +00:00
enricobuehler	f869b434ba	fix(host): input follows session per-connect + restore-guard on desktop switch ... Two fixes from live Bazzite testing of the managed-Gaming + mid-stream work: 1. Input now FOLLOWS the active session. The host-lifetime injector was pinned to the first backend it opened and only reopened on an inject FAILURE — but with Feature A keeping the managed gamescope warm, its EIS socket stays alive, so a switch to the KDE desktop + reconnect kept injecting into the idle gamescope (input silently dead on KDE). injector_service_thread now compares the resolved input backend (default_backend() ← PUNKTFUNK_INPUT_BACKEND, set per connect by apply_input_env, and on a mid-stream switch) each event and reopens when it changes. Fixes input on a Gaming->Desktop reconnect AND Feature B's mid-stream input re-route, with no plumbing. 2. Debounced TV-restore no longer yanks you back to gaming. do_restore_tv_session now checks detect_active_session(): if a desktop session is active (the user switched), it tears down the idle managed gamescope but does NOT restart the gaming autologin. Observed live: the restore fired and restarted gamescope-session-plus@ogui-steam while the client was already on the KDE desktop. Also: document PUNKTFUNK_SESSION_WATCH (Feature B opt-in) in the Bazzite host.env and correct the managed-default description. Compiles, clippy/fmt clean, 78 tests.

enricobuehler	c5ee9871ec	style(host/gamescope): wrap long PENDING_RESTORE assignment (rustfmt) ... The schedule_restore_tv_session assignment exceeded 100 cols; rustfmt wraps it. The fix was made post-commit but only m3.rs was staged for 95a820b, so CI's fmt --check failed on the committed unwrapped line. Stage the wrap.

enricobuehler	95a820b68a	feat(host/m3): mid-stream session-switch watcher (Feature B, opt-in) ... Feature B: while streaming, follow a Gaming<->Desktop switch on the box without a reconnect. A ~1s watcher thread (session_watcher_loop) self-baselines on the live ActiveKind and, when it changes and stays changed for a 3s debounce (the old/new compositors coexist briefly during a switch), sends a SessionSwitch to the encode loop. The loop's new rebuild slot — taking precedence over a queued mode change — retargets the process env (apply_session_env/apply_input_env) and rebuilds the WHOLE backend in place at the SAME client mode (vdisplay::open + build_pipeline_with_retry), reusing the proven mode-switch rebuild path: the Session + send thread (QUIC control + UDP data plane + side planes) stay up, the client sees a brief freeze then an IDR. Old pipeline kept on a rebuild failure (transient vs permanent classified via is_permanent_build_error). Input re-routes via the host-lifetime injector's lazy reopen against the new PUNKTFUNK_INPUT_BACKEND. Opt-in via PUNKTFUNK_SESSION_WATCH (off by default; never under an explicit PUNKTFUNK_COMPOSITOR pin), so it lands inert and is promoted to default only after live validation on a real Bazzite Gaming<->KDE flip. The watcher snapshots the SessionEnv so only the encode thread writes process env. Compiles, clippy/fmt clean, 78 host tests pass.

enricobuehler	c25706b355	feat(host/gamescope): managed-default Gaming with debounced TV-restore ... Feature A: in Gaming Mode, default to a host-managed gamescope at the CLIENT's mode (tear the TV's autologin down on connect) instead of attaching to the running TV session — so the client receives ITS resolution (capture == encode == client mode, fixing the InitializeEncoder size mismatch the attach path hit), not the TV's 4K. Reliability is the debounce: restore_managed_session() now SCHEDULES the TV restore RESTORE_DEBOUNCE (5s) after the last disconnect via a host-lifetime worker, instead of restoring immediately per-disconnect. A reconnect inside the window cancels the pending restore and reuses the still-warm managed session (create_managed_session clears PENDING_RESTORE at the top) — so a quick reconnect (e.g. a controller hiccup) never triggers a gamescope stop/relaunch, which is the per-connect churn that leaked NVIDIA GPU context on F44 (the black-screen reconnect). - vdisplay/gamescope.rs: PENDING_RESTORE + RESTORE_DEBOUNCE; schedule_restore_tv_session (debounced), do_restore_tv_session (the actual restore, worker-driven), start_restore_worker (100ms tick, RAII keepalive handle). create_managed_session cancels the pending restore + reuse path unchanged. - vdisplay.rs: apply_input_env flips gamescope to managed-DEFAULT; PUNKTFUNK_GAMESCOPE_ATTACH (or an explicit _NODE) opts back to attach for couch-on-TV; _MANAGED forces managed. restore_managed_session schedules; new start_restore_worker wrapper. - m3.rs serve(): hold the restore worker for the host lifetime. - bazzite host.env: document managed-default + the ATTACH opt-out. Compiles, clippy-clean, 78 host tests pass. F44 single stop/start leak to be verified live on the box. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-14 22:34:33 +00:00
enricobuehler	66c2bee183	feat(packaging/bazzite): one-shot KDE Desktop-mode setup for the host ... The session-aware selector drives a KWin virtual output at the client's resolution when the Bazzite box is in KDE Desktop Mode — validated live. But a normal KDE login withholds two things the headless host needs: 1. KWIN_WAYLAND_NO_PERMISSION_CHECKS=1 — so KWin exposes the privileged zkde_screencast virtual-output protocol to an external client. 2. the kde-authorized RemoteDesktop grant — so libei input auto-approves instead of popping a dialog a headless host can't answer. Add packaging/bazzite/kde-desktop-setup.sh (idempotent, no root): writes the environment.d KWIN drop-in and seeds the grant DB (shipped at /usr/share/punktfunk/headless/kde-authorized) into ~/.local/share/flatpak/db/, restarting the portal chain. Ship it via the RPM at /usr/share/punktfunk/bazzite/ and document it in the Bazzite README (new §6.5). Gaming Mode needs none of this (auto-attach).

enricobuehler	6f77574876	feat(host/vdisplay): per-connect active-session backend selection ... Bazzite/SteamOS boxes flip between Steam Gaming Mode (gamescope) and a KDE/GNOME desktop. The host statically read PUNKTFUNK_COMPOSITOR / XDG_CURRENT_DESKTOP once, so switching to Desktop Mode failed the stream, and the gamescope managed-session path stopped+relaunched the autologin per connect — leaking GPU context on F44 (reconnect → black screen). Replace the static read with a runtime probe of the live session and route each connect to the right backend, churn-free: - vdisplay::detect_active_session() probes /proc for the running compositor of our uid (gamescope|kwin_wayland|gnome-shell|sway, desktop outranks a leftover gamescope) + scans the runtime dir for the live wayland-* socket. Returns an ActiveKind + the SessionEnv (WAYLAND_DISPLAY/XDG_RUNTIME_DIR/DBUS/ XDG_CURRENT_DESKTOP) that targets it. - apply_session_env() writes that into the process env per connect (host serves one session at a time), so every backend (capture + input) opens against the live session; apply_input_env() points input at the matching backend and selects gamescope ATTACH (no managed restart) unless PUNKTFUNK_GAMESCOPE_MANAGED. - resolve_compositor() (native path) auto-detects + applies; explicit PUNKTFUNK_COMPOSITOR still wins (legacy/CI/forcing). detect() is now active-aware for the GameStream/mgmt callers too. - Bazzite host.env drops the static gamescope force; documents auto-detection + the optional overrides. Result: Desktop Mode → KWin/Mutter virtual output at the client's mode (churn-free, the reliable path); Gaming Mode → attach to the running gamescope (no SIGSEGV/GPU leak on reconnect).

enricobuehler	0bc60ebc44	fix(host/gamescope): free Steam from the autologin TV session while streaming ... On a Bazzite host that autologins into gaming mode on a physical display (the F44 default: gamescope-session-plus@ogui-steam on the TV), Steam — single-instance — is held by that session, which renders to the TV's native mode. The host-managed session then can't start its own Steam, so it captured the TV's 4K output instead of the client's mode (stretched). On F43 the box wasn't in gaming mode, so the host's Steam was the only one. Fix: on connect, the host-managed gamescope path stops any running autologin `gamescope-session-plus@*` unit (frees Steam) before launching its own session at the client's mode; on client disconnect (`restore_tv_session`, called from serve_session teardown) it stops our session and restarts the autologin one, so the TV returns to gaming mode by default when no one is streaming. Stopping the `--user` unit sticks (Relogin only fires on the full logind session ending — verified live), so no sddm config change is needed. Cost: a Steam cold-start per connect, given single-instance. No-op on non-Bazzite / headless boxes (nothing to stop → nothing to restore).

enricobuehler	a59abe2e3e	fix(apple/gamepad): reclaim the PS/Home button from the macOS system gesture ... The earlier buttonHome handler wasn't enough: on macOS the SYSTEM grabs the DualSense Home/PS button by default (opens Launchpad's Games folder), so it never reached the app. The fix is to disable the system gesture on the element — `physicalInputProfile.buttons[GCInputButtonHome].preferredSystemGestureState = .disabled` (Apple's documented mechanism) — which hands the button to us. Then drive `guide` DIRECTLY from that element's pressedChangedHandler instead of via buttonMask: the legacy `extendedGamepad.buttonHome` is unreliable/often nil even when the physical element exists, so reading it in the mask dropped presses. `sendGuide` folds the bit into `buttons` so a held PS button still releases on focus loss. On tvOS the element is reserved (nil) → the block no-ops. The host already maps BTN_GUIDE → the DualSense PS bit, so this completes the chain.

enricobuehler	36107018a8	feat(apple/library): mTLS — authenticate by the paired identity, drop the token ... Phase 3: the Apple library now talks to the host's HTTPS mgmt API (b4a85a8) over mTLS using this client's persistent identity — the SAME cert the host paired over QUIC — so there is NO manual token anymore. - ClientTLS: builds a SecIdentity from the stored PEM (CryptoKit parses the rcgen P-256 PKCS#8 key → x963 → SecKey; the cert PEM → SecCertificate; SecIdentityCreateWithCertificate pairs them via the Keychain). macOS-only for now (that API is unavailable on iOS — a PKCS#12 path would be needed there; the client is macOS-first). - LibraryTLSDelegate: pins the host's self-signed cert by the fingerprint the client already trusts, and presents the identity for the client-cert challenge. - LibraryClient.fetch now does GET https://…/library with the identity + host fingerprint; the whole connection form (port + token) and StoredHost.mgmtToken/setMgmt are gone — the library "just works" for a paired host. 401 → "pair with the host first". Can't compile Swift on the Linux box; CI (apple.yml) compiles the macOS path incl. the Security/CryptoKit code. Runtime (SecIdentity build + the mTLS handshake) needs Mac validation. Pairs with the host mTLS already landed + live-tested. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-14 17:47:19 +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	8c2e245c8b	fix(apple/cursor): disable the client-side cursor (gamescope traps input) ... The client-side cursor positions the host pointer with ABSOLUTE events, but gamescope's input socket (EIS) grants only a relative pointer — the host drops the absolute events (libei.rs: no PointerAbsolute → not emitted), so the pointer never moves and clicks/scroll land on the stuck position. Auto-mode enabled exactly this on gamescope, making all input appear dead until toggled off. Force `cursorVisible = false`, neuter the ⌘⇧C toggle, and hide the now-inert Settings picker. The resolution logic + handlers are kept (commented) for when per-compositor gating (KWin/GNOME/Sway have an absolute pointer) or a synthetic-cursor-over-relative path lands. Relative capture (the working path) is now always used. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-14 17:14:57 +00:00
enricobuehler	36a04e667c	fix(apple): capture the PS/Home button + fullscreen only while streaming ... Two issues from live Mac testing, plus a requested fullscreen option: - PS button: the Home/PS button (→ guide; the host maps it to the DualSense PS bit) does not reliably fire GCExtendedGamepad.valueChangedHandler on macOS, so its presses were dropped. Add a dedicated buttonHome.pressedChangedHandler that re-syncs. The host already maps BTN_GUIDE→PS, so this is the missing client half. - Fullscreen: a macOS FullscreenController (NSViewRepresentable) takes the window fullscreen while a session is up (incl. the trust prompt over the blurred stream) and restores it on the host list — so only the stream is fullscreen, not the picker. New `fullscreenWhileStreaming` setting (default on) + a Settings "Window" toggle. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-14 16:14:37 +00:00
enricobuehler	01409d9d8a	fix(host/dualsense): report full battery + log rumble forwarding ... Two DualSense (UHID) fixes surfaced live on the Bazzite host: - Battery: serialize_state never set the input report's status byte (struct off 52 → r[53]), so hid-playstation read battery capacity 0 and SteamOS warned "low battery" even on a fully-charged pad. Set it to 0x0A (discharging, low nibble 0xA → 100 %) — a virtual pad has no real cell. (Forwarding the client pad's real charge is a later feature.) Regression assert added to the layout test. - Rumble diagnostic: log the silent→active transition when forwarding a buzz on the 0xCA plane, so a live test can tell "host never receives rumble from the game" (Steam Input / parse) apart from "client doesn't render it". Once per buzz, no spam. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-14 16:14:28 +00:00
enricobuehler	5706e7ebf4	feat(apple/library): launch a picked title (step 4 client side) ... Tapping a game in the (flagged) library now starts a session that asks the host to launch it — the picked GameEntry id rides the connect down to the host, which resolves it against its own library (27e5865). - PunktfunkConnection.init gains `launchID` and calls the new punktfunk_connect_ex4 (wrapping it in withOptionalCString; nil = host default). - Threaded SessionModel.connect(launchID:) → ContentView.connect(_:launchID:) → a `launchTitle(host, id)` helper that dismisses the browser and connects. - LibraryView gains `onLaunch`; cards become buttons that fire it. Wired on every platform (ContentView sheet on macOS/iOS, HomeView destination on tvOS) via a new `onLaunchTitle` closure on HomeView. Settings footer updated (launch is live now). Can't compile Swift on the Linux box; CI (apple.yml) verifies. The host side of this chain is live-validated on the dev box: a client `--launch custom:<id>` made the host resolve the id and spawn gamescope running the title (see 27e5865).

enricobuehler	27e58658af	feat(launch): punktfunk/1 launch integration — client picks a title, host runs it ... Plan step 4 (plumbing + host behavior). A client can ask the host to launch a library title on connect; the host resolves it against ITS OWN library and runs it in the session — the client sends only the store-qualified id, never a command, so a remote peer can't inject one. - Protocol (quic.rs): `Hello.launch: Option<String>` (the GameEntry id). Appended after `name`; when launch is present but name absent, a zero-length name placeholder keeps the offset deterministic — so a Hello with neither field stays byte-identical to the bitrate-era 26-byte form (test-asserted). Old peers ignore it; new hosts decode None from old clients. Round-trip + back-compat + truncation tests. - Host: `library::launch_command(id)` resolves id → command via the host's own library — `steam_appid` → `steam steam://rungameid/<appid>` (appid validated as digits, the only client-influenced part), `command` → the host-stored command verbatim (trusted, never from the client). m3.rs sets PUNKTFUNK_GAMESCOPE_APP from it before bringup, exactly as the GameStream /launch path does (one session at a time). Unit-tested incl. an injection-attempt guard. Takes effect on the bare-spawn gamescope path; a no-op on a shared desktop / attach-to-existing session. - C ABI: `punktfunk_connect_ex4` adds `launch_id` (NULL = none); `_ex3` now delegates to it. Threaded through NativeClient::connect → WorkerArgs → Hello. - client-rs gains `--launch ID` (headless testing); client-linux passes None (no picker yet). Header regenerated. Next: the Apple library grid passes the picked id via punktfunk_connect_ex4. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-14 14:56:18 +00:00
enricobuehler	1b610d6bf5	feat(apple/library): experimental game-library browser (flagged off) ... Plan step 3 — the Apple client surfaces the host's game library, behind a feature flag (`DefaultsKey.libraryEnabled`, default OFF). Browsing only; launching a chosen title is step 4. - PunktfunkKit `LibraryClient`: Codable GameEntry/Artwork/LaunchSpec mirroring crates/punktfunk-host/src/library.rs, and an async fetch of GET /api/v1/library with a bearer token. Typed LibraryError guides setup (the common case is "needs a --mgmt-token"). `Artwork.posterCandidates` = portrait → header → hero. - `LibraryView`: cross-platform poster grid (LazyVGrid, AsyncImage that walks the art candidates past load failures to a text placeholder), a store badge, and an inline Connection form (mgmt port + token) that surfaces when the API is unreachable / 401 / no token set. Read-only. - StoredHost gains `mgmtPort`/`mgmtToken` (the mgmt API is a distinct port from the data plane and needs a token off-loopback). Both OPTIONAL — synthesized Decodable ignores property defaults but treats a missing Optional as nil, so older saved hosts decode unchanged (a defaulted non-optional would wipe the list). HostStore.setMgmt. - Entry point: a flag-gated "Browse Library…" host-card context action → LibraryView (sheet on macOS/iOS, pushed on tvOS), mirroring the pair/speed-test plumbing. Plus a Settings "Experimental" toggle. Can't compile Swift on the Linux dev box; CI (apple.yml: swift build + swift test on the mac mini) verifies the macOS path. Added LibraryClientTests (decode + art order) for `swift test`. iOS/tvOS-only branches mirror existing patterns. Live-verify on the Mac pending.

enricobuehler	6136ba4c72	feat(web/library): game library page — grid + custom-entry CRUD ... Consumes the new library API (6351d51) via the orval-generated hooks. A poster grid over GET /api/v1/library (all stores merged), plus create/edit/delete for custom entries — the admin-UI half of "create custom entries via the web console". - GameCard: portrait (600×900) art with an onError fallback chain portrait → header → text placeholder (many Steam titles lack a 600×900 capsule). A store badge marks Steam vs Custom; only custom cards expose edit/delete. - Inline add/edit form (title + portrait/hero/header URLs + optional launch command, mapped to LaunchSpec{kind:"command"}) wired to useCreateCustomGame / useUpdateCustomGame / useDeleteCustomGame; the CRUD id strips the `custom:` prefix; every mutation invalidates the library query. QueryState handles load/empty/error. - Nav entry (LibraryBig) + en/de i18n strings. `bun run lint` (tsc) and `bun run build` both green.

enricobuehler	6351d516e0	feat(host/library): game library API — Steam adapter + custom store ... A new `library` module + four mgmt endpoints surface the host's games to clients (plan: "surface the user's games"). An adapter layer (`LibraryProvider`) so future stores (Heroic/Epic, GOG, Lutris) slot in behind one uniform `GameEntry`. - SteamProvider: reads the LOCAL Steam install — no Steam Web API key, no network. Installed titles from steamapps/appmanifest_<appid>.acf; extra library folders (incl. paths with spaces) from libraryfolders.vdf; candidate roots cover classic, Flatpak and Deck layouts, canonicalized + deduped (the .steam/{steam,root} symlinks all fold to one). Runtimes/redistributables (Proton, Steam Linux Runtime, Steamworks Common, SteamVR) filtered out. Artwork = the public Steam CDN by appid (portrait/hero/logo/header), fetched directly by the client. - Custom store: ~/.config/punktfunk/library.json, write-then-rename persisted, CRUD'd via the API — the "create custom entries via the admin web UI" requirement. - API (under /api/v1, OpenAPI-documented + checked in): GET /library (all stores merged, sorted), POST /library/custom, PUT/DELETE /library/custom/{id}. - `punktfunk-host library` subcommand dumps the resolved library as JSON (diagnostic, mirrors `openapi`). Validated live against the real Steam library on the Bazzite box: 89 appmanifests → 78 games (11 tools filtered), correct titles/sort, and the CDN art URLs return 200. 5 unit tests for the VDF/ACF parsing, tool filter, art URLs, custom mapping.

enricobuehler	ee7984beb0	feat(packaging/arch): split package — add punktfunk-client for the Deck ... The Decky plugin (b3f98a5) launches `punktfunk-client`, but the Arch package only shipped the host, so the Deck had nothing to launch. Convert the PKGBUILD to a split package (pkgbase=punktfunk → punktfunk-host + punktfunk-client), mirroring the rpm subpackages and the two deb build scripts: - punktfunk-host: unchanged artifact set + NVENC/compositor optdepends. - punktfunk-client: the GTK4 binary + io.unom.Punktfunk.desktop + the hidraw udev rule + the 32MB recv-buffer sysctl; depends gtk4/libadwaita/sdl3/ffmpeg/pipewire/ opus; optdepends libva-mesa-driver (VAAPI decode on the Deck's AMD APU, software fallback otherwise). New punktfunk-client.install scriptlet. - build-sysext.sh now derives the package name from the file, so it wraps either the host OR the client into a systemd-sysext .raw — on a Deck you wrap the client. - README: split-package usage + a "Steam Deck (the client)" section tying the sysext to the Decky plugin (client is on PATH → plugin launches `punktfunk-client --connect host:port`). Clarified the VAAPI gap is host-ENCODE only; the client DECODES via VAAPI on the Deck today, so streaming to a Deck works now.

enricobuehler	b3f98a5d7d	feat(clients/decky): SteamOS Gaming-Mode launcher plugin (spike) ... A Decky Loader plugin so a Steam Deck / SteamOS box can launch the punktfunk client from Gaming Mode using REAL Steam UI components (it runs inside Steam's CEF, so the panel is built from @decky/ui — the literal Big Picture primitives, not a replica). - Frontend (src/index.tsx, @decky/api + @decky/ui): a Quick Access Menu panel — Refresh → discover hosts, a native list (name, ip:port, pairing flag), tap to connect with a status toast, Disconnect. - Backend (main.py): discover() shells `avahi-browse -rpt _punktfunk._udp` and parses the host's advertised TXT keys (proto/fp/pair/id from discovery.rs), dedup by id preferring IPv4; connect() resolves + spawns `punktfunk-client --connect host:port` (gamescope composites its video like a game), tracking the child; disconnect() terminates it. - Mirrors the current official Decky template (the API moved to @decky/ui + @decky/api). Frontend builds clean (pnpm build → dist/index.js); main.py py_compiles. dist/ + node_modules gitignored — build on the Deck per README. Spike scope: launcher only, runtime untested (no Deck here). Next on this track: the in-stream Quick-Access overlay (volume/disconnect/stats over the running stream) and a fuller real-components UI. Client decode on the AMD Deck is the existing VAAPI path; the host-encode VAAPI gap is separate (NVIDIA host = NVENC).

enricobuehler	c64816c70a	feat(apple): client-side cursor for gamescope sessions (toggle + shortcut) ... gamescope's PipeWire capture carries no cursor (verified upstream — it never composites the cursor or adds SPA_META_Cursor), so the cursor must be drawn on the client. New macOS "cursor-visible" capture mode: instead of disassociating+hiding the system cursor and sending relative deltas (the game path, unchanged), it keeps the system cursor visible over the stream and sends ABSOLUTE positions (MouseMoveAbs), mapped through the video's aspect-fit (AVMakeRect) to host pixels with the letterbox bars dropped. The visible system cursor IS the client cursor — zero added latency, no double cursor (gamescope draws none), accurate (the client drives the host's absolute mouse). - Default: on iff the session's resolved compositor is gamescope (via the new punktfunk_connection_compositor getter, fc30307). - Settings: "Cursor in stream" → Auto (gamescope) / Always / Never. - Shortcut: ⌘⇧C toggles it live mid-session (re-engages capture so disassociation + abs/rel forwarding swap atomically); shown in the HUD. macOS-only (the visible-cursor mode lives in the macOS StreamView). Verified to compile + link via xcodebuild Release on the Mac; runtime behavior (cursor landing, hover forwarding) to be confirmed live. Rust ABI side committed separately.

enricobuehler	fc30307a87	feat(abi): expose the host-resolved compositor to clients ... Add punktfunk_connection_compositor() (mirrors punktfunk_connection_gamepad): a client getter for the compositor the host actually resolved for the session, read from Welcome.compositor and threaded through NativeClient.resolved_compositor. The Apple/Linux clients use it to enable the client-side cursor by default on gamescope sessions, whose PipeWire capture carries no cursor (verified upstream). Header regenerated.

enricobuehler	c548155dd9	feat(packaging/arch): Arch + SteamOS install target (PKGBUILD + sysext) ... Add packaging/arch: a PKGBUILD mirroring the rpm/deb artifact set (binary, udev rule, 32MB sysctl, systemd USER units with ExecStart rewritten, headless helpers, env templates, openapi), a pacman .install scriptlet, a systemd-sysext builder for immutable SteamOS, and a README. Builds the working tree via PF_SRCDIR (CI/dev) or a git tag (AUR). Arch's stock ffmpeg already ships NVENC, so deps collapse to ~10 packages with nvidia-utils/compositors as optdepends (never hard-depend on the driver, same invariant as rpm/deb). SteamOS delivery is a **systemd-sysext** (overlays /usr read-only from writable /var/lib/extensions/, survives A/B OS updates, no steamos-readonly disable) — pacman/distrobox/flatpak are all unsuitable for a host that needs uinput/uhid, the host PipeWire socket, the GPU node, and to spawn a compositor. KNOWN GAP, documented prominently: encode is NVENC-only (src/encode/linux.rs has no VAAPI backend), so this works on Arch+NVIDIA (and bazzite-deck-nvidia) but an AMD Steam Deck installs yet cannot encode until a hevc_vaapi backend is written — a code change, not packaging.

enricobuehler	abc057fbfe	fix(ci/apple): scope iOS/tvOS archive signing to the device SDK ... A global PROVISIONING_PROFILE_SPECIFIER on the xcodebuild command line is applied to every target in the graph, including the shared SwiftPM compiler- plugin macros (OnceMacro/SwizzlingMacro/AssociationMacro). Those build for the macOS host and reject a provisioning profile, so the iOS/tvOS device archives failed at build-description time with "<macro> does not support provisioning profiles". (The macOS archive is immune: its host-SDK macros carry CODE_SIGNING_ALLOWED=NO, so the global specifier is silently ignored there.) Move the signing settings into a generated -xcconfig and condition the profile + identity on the device SDK ([sdk=iphoneos*] / [sdk=appletvos*]). xcconfig conditionals are honored and a command-line -xcconfig outranks target settings, whereas a CLI "SETTING[sdk=..]=val" is mis-parsed — both verified via xcodebuild -showBuildSettings against the real project. The profile now lands on the app/framework slices only; the macosx-host macros get nothing. macOS App Store archive is unchanged (already green; installer cert now present on the runner). tvOS upload may still need tvOS on the App Store Connect record, but that step is continue-on-error.

enricobuehler	8425cd0826	fix(encode): probe each GPU's real max bitrate instead of failing (or blind-capping) ... Root cause of the Mac "session ended" at 880 Mbps / 1.3 Gbps: the host requests a bitrate NVENC can't express at any codec level and `avcodec_open2` returns EINVAL ("Invalid argument"), so the pipeline build fails after 4 identical retries and the session dies at encoder init — before a single video packet (which is why the client's UDP counters never moved). The ceiling is GPU/driver-specific: an RTX 4090 caps HEVC at ~800 Mbps (Level 6.2 High tier) and rejects above it, while an RTX 5070 Ti accepts 1.3 Gbps. Rather than hard-cap every build to a conservative guess (which would needlessly throttle capable cards), open_video now PROBES: open at the requested bitrate, and step down (codec spec ceiling, then 0.75x to a 50 Mbps floor) ONLY when this GPU returns EINVAL. Each GPU runs at its own real maximum — the 5070 Ti keeps 1.3 Gbps, the 4090 lands at 800 Mbps and streams instead of dying. Non-EINVAL failures (no GPU, bad mode, OOM) still surface immediately rather than being masked by retries. Codec::max_bitrate_bps is now just the first step-down candidate, not a clamp.

enricobuehler	9f92dc505b	fix(client/pkg): ship 32MB UDP recv-buffer sysctl with the Linux client ... The client asks the kernel for a 32 MB SO_RCVBUF, but the kernel silently clamps it to net.core.rmem_max — whose default is far too small. A too-small recv buffer is the dominant client-side wall above ~1 Gbps. Measured live (Fedora host -> two clients, real 2.5G LAN, GSO off): a client capped at 4 MB rmem_max dropped 31.6% of a 2 Gbps stream at the receiver, while a 32 MB client delivered the same 2 Gbps at 0.0% loss. The host already shipped this tuning; the client packages didn't (the RPM's %post even referenced the host-only file), so a client-only install streamed lossy at high bitrate. Add scripts/99-punktfunk-client-net.conf (rmem/wmem = 32 MB, distinct filename so host+client can coexist) and ship+apply it from both the .deb (build-client-deb.sh) and the RPM client subpackage (install, %files client, %post client). For reference the full ladder (punktfunk speed-test): 0% loss to 1.5 Gbps on a 4 MB client; 31.6% at 2 Gbps on 4 MB vs 0% at 2 Gbps on 32 MB. iperf3 put the raw link at ~2.35 Gbps TCP / ~2.4 Gbps UDP, so the stack now tracks the wire given a big enough recv buffer.

enricobuehler	4d26f61e40	fix(net/gso): fall back to sendmmsg on EMSGSIZE instead of tearing down ... Enabling PUNKTFUNK_GSO on a host whose egress MTU is below our UDP segment size made every GSO send return EMSGSIZE (code 90, "Message too long") — the kernel validates each GSO segment against the device MTU at send time, which plain sendmmsg does not. EMSGSIZE wasn't in gso_unsupported() (nor is_transient_io), so it propagated as a fatal "send failed — stopping stream" and instantly killed every session the moment GSO was on (observed live: connection fails instantly / speed-test 0 Mbps). Add EMSGSIZE to gso_unsupported() so it latches GSO off for the process and finishes via sendmmsg — the standard "GSO not usable on this path" fallback. Measured after: the same host+path does 1 Gbps at 0.0% loss over the real LAN via sendmmsg (and the host send path sustains a 2 Gbps probe with send_dropped=0), so GSO is a >2 Gbps optimization, not required for 1 Gbps.

enricobuehler	16ccc7c876	fix(net): don't tear the stream down on a connected-UDP ICMP blip (ECONNREFUSED) ... Root cause of the Mac "session ended" at higher bitrates. The video data plane is a *connected* UDP socket; with data-plane hole-punching the path can blip and the kernel surfaces an asynchronous ICMP port-unreachable/reset as ECONNREFUSED / ECONNRESET on a later send or recv. Both the host send loop and the client poll_frame treated that as fatal and tore the session down: ERROR punktfunk_host::m3: send failed — stopping stream error=send_sealed: Io(ConnectionRefused, code 111) <-- observed live That also cascades: a transient ICMP makes the client's poll_frame bail and close its data socket, which makes the host's next send get a *real* ECONNREFUSED, which tears the host side down too — exactly the "broke at 500 Mbps+" report. Fix: classify ECONNREFUSED/ECONNRESET alongside WouldBlock as transient (a lossy drop / "no data this poll"), never a teardown, at every data-path send/recv site (send, send_batch, send_gso, recv, recv_batch x2, recv_batch_x). FEC + the next frame/RFI recover; if the peer is genuinely gone the QUIC control plane's conn.closed() ends the session cleanly (no infinite "stream into the void"). This is the standard connected-UDP rule that ICMP errors are advisory — doubly true with hole-punching. Adds is_transient_io() + a unit test.

enricobuehler	b140cd6837	feat(apple/macos): App Sandbox + entitlements, wire Mac App Store TestFlight ... The Mac App Store requires App Sandbox, which the macOS app didn't declare. App Sandbox is macOS-only (invalid on iOS/tvOS, fails upload validation), so the macOS target now uses a dedicated Config/Punktfunk-macOS.entitlements while iOS/tvOS keep the shared Config/Punktfunk.entitlements (unchanged). The single macOS app is sandboxed for BOTH channels — the Developer ID DMG is codesigned with the same file — so the local build equals what App Store users get. Entitlement set (verified against the code + Apple docs): - app-sandbox, network.client. - network.server: NOT optional despite the client being outbound-only — the sandbox gates the bind() syscall as network-bind, and quinn (quic.rs) + the raw-UDP plane (transport/udp.rs) both bind explicitly, so host->client datagrams never arrive without it (the classic QUIC-under-sandbox trap). - device.audio-input (mic uplink), device.bluetooth + device.usb (Xbox/DualSense controllers over BT/USB via GameController), keychain-access-groups (existing). Omitted: device.hid (undocumented), files.user-selected.* (no pickers), networking.multicast (Bonjour browse is exempt; requesting it breaks signing). CI (release.yml): add a macOS App Store archive+upload-to-TestFlight step mirroring the iOS lane (manual Apple Distribution signing + the 'Punktfunk macOS App Store Distribution' profile, app-store-connect/upload, installer-signed pkg), continue-on-error until the portal prereqs exist; point the Developer ID DMG codesign at the sandboxed entitlements. Docs (ci.md) + clients/apple README updated; the runner additionally needs the macOS platform on the App Store Connect record + the '3rd Party Mac Developer Installer' cert. Verified: signed Debug build embeds exactly the intended entitlements (codesign -d --entitlements), swift build green against the rebuilt xcframework.
