New crate crates/punktfunk-client-linux (binary punktfunk-client), the native Linux client on the Option A architecture (2026-06-12 research): - GTK4/libadwaita shell linking punktfunk-core directly (no C ABI): mDNS host list, TOFU fingerprint prompt, SPAKE2 PIN pairing dialog, preferences (mode/bitrate/gamepad/shortcut capture), stats overlay, --connect host[:port] for scripting. - Video: FFmpeg software HEVC decode (LOW_DELAY, slice threads) -> RGBA -> GdkMemoryTexture inside GtkGraphicsOffload (the dmabuf subsurface path lights up when VAAPI lands; black-background keeps fullscreen scanout-eligible). - Audio: Opus -> PipeWire playback stream, the host virtual-mic's adaptive jitter ring inverted. - Input: keyboard as the exact inverse of the host VK table (evdev keycodes, layout-independent; unit-tested), absolute mouse through the Contain-fit transform, WHEEL_DELTA(120) scroll, compositor shortcut inhibition while streaming, Ctrl+Alt+Shift+Q release chord, F11 fullscreen. SDL3 gamepad capture (single pad-0 model) + rumble and DualSense lightbar feedback on the same thread. - Session pump owns video+audio pulls; the gamepad thread owns rumble+hidout — possible because NativeClient's plane receivers are now mutexed, making it Sync (Arc-shared, compiler-verified per-plane contract instead of the ABI's manual assertion). - Linux-gated deps + a stub main keep cargo build --workspace green on macOS. Validated live against serve --native on this box: 1920x1080@60, locked 60 fps, capture->decoded p50 ~6.4 ms (software decode, debug build). Teardown keys off AdwNavigationPage::hidden — NavigationView push fires a transient unmap/map cycle that must not end the session. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
