Everything the macOS app does that stage 1 lacked, before any new
feature work (user directive):
- Input capture is now a deliberate, reversible STATE (Moonlight-
style): engaged on stream start and click-into-video (the engaging
click is suppressed), released by Ctrl+Alt+Shift+Q (toggles) or
focus loss; held keys/buttons are flushed host-side on release;
cursor hiding + shortcut inhibition follow the state; HUD hint when
released. Per-session window handlers disconnect with the page.
- Gamepads: app-lifetime SDL service (GamepadManager parity) — pad
list + "Forwarded controller" pin in Settings (auto = most recent),
"Automatic" pad TYPE resolves from the physical pad at connect;
DualSense touchpad contacts + ~250 Hz motion samples on the 0xCC
plane (Swift GamepadWire scale constants); feedback grows adaptive-
trigger replay and player LEDs via raw DS5 effects packets (the
wire's 11-byte blocks drop into SDL_SendGamepadEffect verbatim);
held pad state zeroed on pad switch/detach. sdl3 "hidapi" feature.
- Microphone uplink: PipeWire capture -> Opus 20 ms -> 0xCB datagrams
(validated live: host received 711 mic packets), Settings toggle.
- Speed test per saved host (Swift's "Test Network Speed…"): 2 s
probe burst, goodput/loss + recommended ~70 % bitrate, one-tap apply.
- Settings: host compositor preference (sent in the Hello), native-
display resolution/refresh resolved from the window's monitor at
connect (new default), bitrate ceiling to 3 Gbit/s.
- Hosts page: saved/trusted hosts section for direct pinned reconnect
(mDNS not required), rebuilt on every page return.
Deliberately not ported: audio device pickers (PipeWire routing owns
this on Linux), resize-to-request_mode (not wired in Swift either),
pointer-lock relative mouse (stage-2 presenter, needs raw Wayland).
DualSense fidelity needs a physical pad to live-verify.

The MouseMoveAbs wire contract packs the client coordinate-space size
as (width << 16) | height in `flags` (same as touch); injectors
normalize against it and drop the event when it is zero. The GTK
client sent flags=0, so KWin's libei path refused every motion
(`emitted=false`) — found via the first real user test from
home-worker-3.
- ui_stream: send_abs() packs the negotiated mode into flags for
motion + click-position events.
- core input.rs: document the contract on MouseMoveAbs itself (it was
only implied by TouchDown's doc).
- client-rs --input-test: add a MouseMoveAbs sweep so the absolute
path stays covered — Moonlight and the Mac client only send relative
motion, which is why this gap survived every prior live test.
Validated live against serve --native: kind=MouseMoveAbs emitted=true.

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.
