enricobuehler db63647337 fix(client-linux): Deck trackpad clicks — bind to the correct pad, stop riding the button plane 
SDL's Steam Deck mapping delivers the pad clicks as gamepad BUTTONS with no
surface identity: the generic `touchpad` button is the LEFT pad's click and
`misc2` the RIGHT's (SDL_gamepad_db.h `touchpad:b17,misc2:b16`). The client
forwarded `touchpad` as wire BTN_TOUCHPAD — which the host maps to the RIGHT
pad click (DualSense convention) — and dropped `misc2` entirely: a left-pad
click registered on the right pad, a right-pad click nowhere, and the
mis-routed state could stick.

Clicks from a multi-touchpad pad now ride the rich plane as TouchpadEx with
their surface, reusing the surface's live contact point (click buttons carry
no position). forward_touch carries the held click through motion frames so a
touch update can't clear a click mid-press, and the flush lifts held clicks on
detach/pad-switch. A DualSense's single touchpad button stays on the button
plane unchanged.

enricobuehler 7eea9836b8 fix(clients): GTK + Decky polish batch from live Deck/Windows testing 
GTK Linux client:
- hosts/library: clicking a card was dead — the handler was on
  FlowBoxChild::activate (never emitted on click); bridge child-activated
  → child.activate() on the FlowBox (ui_hosts, ui_library).
- stream: the Ctrl+Alt+Shift+D/Q/S chords (and all key forwarding) were
  dropped because the key controller sat on the overlay, which loses focus
  to the header back button after nav.push+fullscreen — move it to the
  window and remove it on teardown.
- video: a mid-session VAAPI decode error rebuilt a software decoder but
  never requested a keyframe, so under the infinite GOP the picture stayed
  gray/frozen forever. Request an IDR on any VAAPI error, keep the hardware
  decoder, and demote to software only after repeated failures.
- stream: fix a per-session Capture↔overlay reference cycle that leaked the
  overlay subtree + the Arc<NativeClient> on every session end — hold the
  overlay weakly.
- stream: accumulate the fractional wheel remainder so precision-scroll
  (Deck trackpad / hi-res wheels) sub-unit deltas aren't dropped.
- gamepad library: keep the launcher smooth on the Deck — freeze the aurora
  and trim the visible card range (fewer 3D offscreen passes) on low-power.
- gamepad: log full pad identity (vid:pid:name:type:virtual) on attach to
  diagnose an empty controller list on the Deck.
- cli: --connect host:<badport> silently did nothing; default to 9777 + warn.
- css: add the missing .pf-neutral pill rule; fix the clipped most-recent
  accent (inset outline instead of a corner-clipped box-shadow bar).

Decky plugin:
- surface the on-screen library browser: label the host-row Games button.
- fix silent pin data-loss — the detached Games modal captured a frozen
  pins array, so pinning a second game clobbered the first; mirror pins in
  a ref and track the modal's pinned ids locally for a live label.
- route pair-required hosts through the pairing modal from the fullscreen
  Stream button (parity with the QAM panel).

enricobuehler 03a488f75d feat(linux-client): gamepad library launcher — console-style coverflow (--browse) 
A controller-driven, chrome-less library launcher for the Steam Deck flow
(the Decky plugin's "Open library on screen" + pinned games, 3122506):
`--browse host[:port]` opens a paired host's game library as a coverflow
over a drifting aurora — A streams the focused title (the id rides the
Hello), session end returns to the launcher, B quits back to Gaming Mode.
`--connect` gains `--launch <id>` for direct-to-game starts; `--mgmt`
overrides the library port. Scope is deliberately library-only: host
selection/settings stay in the touch UI, pairing stays in the plugin (no
dialog can map under gamescope — every state renders in-page).

- gamepad.rs menu mode: the worker holds the active pad open while idle
  (WITHOUT the Valve HIDAPI drivers — Deck lizard mode survives) and
  translates it through a pure MenuNav state machine: edge-triggered
  buttons, held-state snapshot on entry/detach (the escape chord that ends
  a stream can't ghost-fire in the menu), 380/160 ms stick/dpad repeat,
  menu rumble ticks. Keyboard fallback (arrows/Enter/Esc) drives the same
  handler — fully usable with no pad, no host (PUNKTFUNK_FAKE_LIBRARY).
- Coverflow: ±38° corridor-facing tilt under per-card perspective
  (gsk rotate_3d), dense overlapping side shelves with paint-order
  restacking (gtk::Fixed draws in child order), opaque card faces + a
  darkening veil for the recede (translucency would bleed the stack
  through). The strip lives in an External-policy ScrolledWindow because
  a bare gtk::Fixed measures its TRANSFORMED children and inflates the
  page min-width past the window.
- Spring-driven motion: semi-implicit Euler in ≤8 ms substeps (a raw
  50 ms frame leaves the stiff recoil spring ringing at ω·dt ≈ 1.2 —
  regression-tested), ζ≈0.85 cursor chase + ζ≈0.55 boundary wobble;
  velocity carries across retargets so held-repeat scrolling glides.
- Shot scene `gamepad-library` (GTK animations force-disabled in shot mode
  — nav transitions froze mid-slide in headless captures); shared poster
  fetch extracted to library::spawn_art_fetch.

Verified here: 21 unit tests (MenuNav, cursor stepping, spring
convergence/stability), clippy -D warnings clean, screenshot scene
pixel-checked, --browse smoke runs (fake-library + unpaired) on the
headless session. On-Deck validation pending (virtual-pad input, lizard
mode, rumble via Steam Input, full Decky→browse→stream→launcher loop).

enricobuehler b0d169f7e6 fix(client-linux): Deck Gaming Mode — auto pad type, real chrome-less fullscreen, leave-to-Gaming-Mode, colour bisect 
- "Automatic" gamepad type resolves to the virtual Steam Deck pad on Deck
  hardware (env SteamDeck / DMI Jupiter|Galileo): the built-in 28DE:1205
  identity is invisible at Hello time — the Valve HIDAPI drivers run
  in-session only and Steam Input shadows the pad with its virtual X360 —
  so auto always fell through to Xbox 360. "steamdeck" is now also
  selectable in Settings.
- Chrome-less launches flatten the window CSS (border-radius/box-shadow)
  and fullscreen at startup: gamescope never ACKs the xdg fullscreen
  state, so adwaita kept the floating-CSD rounded corners + shadow
  visible over the stream.
- Gaming-Mode --connect launches quit on session end, so Steam ends the
  "game" and the Deck returns to Gaming Mode — previously the app popped
  to its own hosts page, stranding the user fullscreen and making the
  escape chord read as broken.
- The capture hint is controller-aware; the chromeless hint teaches the
  hold-chord ("hold L1+R1+Start+Select to leave") and a quick chord press
  re-flashes it.
- Colour bisect for the reported off-colours on the VAAPI dmabuf path:
  graphics offload defaults OFF under gamescope (a subsurface hands the
  NV12 CSC to the compositor), PUNKTFUNK_OFFLOAD=1|0 overrides, and each
  colour-signaling change logs whether GDK accepted the BT.709-narrow
  color state (fallback = GDK's BT.601 dmabuf default).

enricobuehler a1daf4cbd2 feat(client/linux): Steam Deck batch — idle gamepad grab, fullscreen streams, in-band HDR colors, gamescope-safe settings, pad-pin persistence 
Root-caused fixes from on-Deck testing (owner + first external tester):

- System input broke while the app was merely OPEN: SDL's Steam Deck HIDAPI
  driver clears the built-in controller's "lizard mode" (trackpad-mouse,
  clicky pads) at device ENUMERATION and keeps feeding the firmware watchdog
  (SDL_hidapi_steamdeck.c InitDevice/UpdateDevice) — and we enabled that
  driver at startup and held every pad open app-lifetime. The Valve HIDAPI
  hints are now enabled only while a session is attached, and only the active
  pad is opened (Settings enumerates via SDL's ID-based metadata getters, no
  open). Close/detach hands the hardware back; the watchdog restores lizard
  mode within seconds. This also unblocks click-to-capture on the Deck (the
  dead trackpad made "input not passed through" a symptom, not a cause).
- Washed-out colors from a Windows host with an HDR desktop: the host ships
  Main10 BT.2020 PQ IN-BAND (correct VUI) while the Welcome still says SDR;
  this client rendered everything as BT.709 narrow. Colour signaling is now
  read per-frame (video::ColorDesc from the AVFrame CICP fields) and drives
  the GdkDmabufTexture color state, the software path's swscale matrix/range
  plus a tagged MemoryTexture for PQ, and an "· HDR" HUD chip — GTK tone-maps
  correctly on SDR displays, mid-session SDR↔HDR flips included. Regression-
  tested against a checked-in Main10 PQ fixture (tests/pq-frame.h265).
- Streams start fullscreen by default (Settings toggle; F11 / the controller
  chord lead out, and the pointer at the top edge reveals the header while
  input isn't captured — a Deck desktop has no F11). Gaming-Mode launches
  (--fullscreen / Deck env) build the stream page with NO header bar at all:
  gamescope doesn't reliably ACK xdg_toplevel fullscreen, so anything keyed
  on is_fullscreen() could leave the title bar drawn over the stream.
- Game Mode settings were uneditable: GTK popovers are xdg_popups, which
  gamescope never maps for nested apps — every ComboRow dropdown flashed and
  died. Under gamescope the preferences dialog now uses in-window selection
  subpages (PreferencesDialog::push_subpage) via a ChoiceRow that stays a
  stock ComboRow on desktops. Covered by an in-process GTK test
  (choice_row_modes, #[ignore]d — needs a display).
- Forwarded-controller pin persists across restarts (Settings::forward_pad,
  stable vid:pid:name key — SDL instance ids are per-run) and survives
  disconnects; automatic selection skips Steam Input's sensor-less virtual
  pad (28de:11ff) so gyro doesn't silently die on Bazzite/Deck.
- "Punktfunk" branding in the About dialog.

enricobuehler 50e25205a0 feat(linux): game library browser; split app.rs into cli/launch/ui_trust 
- library.rs + ui_library.rs: the host's unified game library over the
  management API (the Apple LibraryClient/LibraryView ported) — mTLS with the
  paired identity, host verified by its pinned cert fingerprint (ureq + rustls,
  unified with the workspace rustls 0.23); posters load async with monogram
  placeholders, and picking a title starts a session that asks the host to
  launch it (the library id rides the Hello).
- app.rs (~800 lines lighter) splits into cli.rs (argv/headless
  pairing/--connect/screenshot scenes), launch.rs (mode resolve + session
  worker + event stream into the UI) and ui_trust.rs (TOFU / SPAKE2 PIN /
  delegated-approval dialogs); ui_hosts/ui_stream reworked around the split.

enricobuehler f3986b8f82 feat(host/steam): shippable usbip/vhci_hcd virtual Deck + client leave-shortcuts 
Steam Deck pass-through (design/steam-deck-passthrough-plan.md), code-complete +
all CI checks green on Linux + adversarially reviewed; on-glass validation pending:

- usbip/`vhci_hcd` virtual Deck transport (inject/linux/steam_usbip.rs) for
  non-SteamOS hosts (Bazzite/generic) — presents a real interface-2 USB Deck so
  Steam Input promotes it. In-process vhci attach (loopback OP_REQ_IMPORT handshake
  → sysfs attach) with a bounded `usbip`-CLI fallback; detach on drop.
- Backed by a vendored, libusb-free trim of the `usbip` crate
  (crates/punktfunk-host/vendor/usbip-sim, MIT + NOTICE; host/cdc/hid + rusb/nusb
  removed; interrupt-IN paced by bInterval).
- Selection ladder raw_gadget (SteamOS fast-path) → usbip (universal) → UHID,
  with PUNKTFUNK_STEAM_USBIP / PUNKTFUNK_USBIP_ATTACH knobs.
- Shared Deck descriptors + the 0x83/0xAE feature contract + a Steam-accepted
  serial consolidated into steam_proto.rs; the raw_gadget backend reuses them.
- Linux client leave-shortcuts: Ctrl+Alt+Shift+D + holding the escape chord
  (L1+R1+Start+Select) >=1.5s end the session (short press still exits
  fullscreen); the chord state resets across sessions.

Also bundles in-progress work already staged in the tree:
- host(kwin): xdg-output logical-geometry mapping so the KWin fake_input backend
  places absolute coordinates correctly under display scaling.
- docs: design/README index entries + design/controller-only-mode.md.

enricobuehler 6c4b439663 feat(clients/steam): M4 — desktop SDL clients capture the rich Steam inputs 
The Linux + Windows native clients (clients/{linux,windows}/src/gamepad.rs) now
capture and send the Steam Controller / Steam Deck rich inputs, so a real Deck
(off Steam Input) or a Steam Controller on a desktop client drives the host's
virtual hid-steam pad end-to-end:

- Set SDL's HIDAPI Steam hints (SDL_JOYSTICK_HIDAPI_STEAMDECK / _STEAM) before
  init so SDL opens Valve devices directly (paddles + both trackpads + gyro as
  first-class SDL gamepad inputs).
- Detect the Deck/SC by VID/PID (0x28DE + 0x1205 / 0x1102 / 0x1142) ->
  GamepadPref::SteamDeck (there is no SDL gamepad type for it), so the host
  builds the virtual Deck with the right identity.
- Map the SDL paddle + Misc1 buttons -> BTN_PADDLE1..4 / BTN_MISC1 (a free win
  for Xbox Elite paddles too).
- Route a SECOND touchpad -> RichInput::TouchpadEx (SDL touchpad 0 = left ->
  surface 1, 1 = right -> surface 2, signed coords); a single touchpad keeps the
  legacy Touchpad. New forward_touch() helper centralizes the choice.
- Track held touchpad contacts per (surface, finger) and lift them on pad
  switch/detach so a contact held at that moment can't stick.
- Sensor (gyro/accel) capture was already generic across pad types.

Linux client builds + clippy clean; the Windows client is a near-verbatim
mirror (windows CI compiles it). On a Deck in Game Mode, Steam Input still holds
the device — the user disables Steam Input for the client (the Decky UX, next);
on a desktop client (or a Deck with Steam Input off) the hints just work.

Remaining M4: Decky Disable-Steam-Input UX, Apple/Android parity, and the C-ABI
PunktfunkRichInputEx + send_rich_input2 (Apple/embedder send path). Not pushed.

enricobuehler 99ae1b9a17 feat(gamepad): add virtual Xbox One/Series + DualShock 4 pad types 
Extends virtual-controller support beyond Xbox 360 + DualSense. Goal: a
physical Xbox One or PS4 pad on the client gets a near-native matching virtual
pad on the host, auto-resolved from the controller type.

Protocol/core:
- GamepadPref gains XboxOne (wire 3) + DualShock4 (wire 4); to_u8/from_u8/
  from_name/as_str + C ABI PUNKTFUNK_GAMEPAD_XBOXONE/_DUALSHOCK4 constants
  (compile-time guard ties them to the enum). Single-byte wire form is
  unchanged, so it's forward-compatible (older peers degrade to Auto).

Host (Linux):
- New UHID DualShock 4 backend (inject/dualshock4.rs) bound by hid-playstation:
  lightbar, touchpad, motion, rumble — DualSense minus adaptive triggers /
  player LEDs / mute. Reuses the DualSense pure state + button mapping; only the
  report byte layout, the real-DS4 HID descriptor, the GET_REPORT handshake
  (0x12 MAC mandatory; 0x02 calibration; 0xa3 firmware) and the touchpad
  resolution (1920x942) differ. Touchpad/motion ride the existing 0xCC plane,
  lightbar the 0xCD Led plane (deduped); rumble the universal 0xCA plane.
- Xbox One/Series is the uinput Xbox-360 backend parameterized with the One S
  USB identity (045e:02ea) for matching glyphs — XInput-identical otherwise.
- PadBackend dispatch + resolver handle both; off Linux the UHID pads and
  One/Series fold into Xbox 360. Windows-host DS4 (ViGEm) deferred.

Clients (auto-resolve physical pad -> virtual type, plus manual settings):
- Linux/Windows (SDL3): SDL_GAMEPAD_TYPE_PS4 -> DualShock 4, _XBOXONE ->
  Xbox One; PadInfo carries the resolved pref; DS4 touchpad/motion capture +
  lightbar already type-agnostic. Linux settings combo + label updated.
- Apple (GameController): GCDualShockGamepad/GCXboxGamepad detection, DS4
  touchpad capture, settings picker entries.
- Android (Kotlin): InputDevice VID/PID auto-detect (matching the other
  clients) + settings entries.
- probe: --gamepad help/aliases.

Also hardens the Android JNI boundary: wrap the teardown + poll-thread shims in
catch_unwind so a panic degrades to a logged no-op instead of aborting the app.

enricobuehler 2f2147b093 refactor: drop milestone names + consolidate clients; loss-recovery & rumble fixes 
Two bodies of work in one commit (the rename moved files the fixes also touched).

Naming/structure cleanup (pre-launch):
- Host modules m3.rs->punktfunk1.rs, m0.rs->spike.rs; CLI m3-host->punktfunk1-host,
  m0->spike; bare `punktfunk-host` now prints help. Types M3Options/M3Source->
  Punktfunk1Options/Punktfunk1Source.
- Clients consolidated out of crates/ into clients/: punktfunk-client-rs->
  clients/probe (crate punktfunk-probe), client-linux->clients/linux,
  client-windows->clients/windows, punktfunk-android->clients/android/native
  (crate punktfunk-client-android; kept [lib] name=punktfunk_android so the JNI
  contract is unchanged). crates/ now holds only core + host.
- Milestone codes M0-M4 purged from code/CLI/CLAUDE.md/README/docs/docs-site,
  kept only in docs/implementation-plan.md. docs/m2-plan.md->
  docs/gamestream-host-plan.md. CI/gradle/flatpak paths updated.

Client loss-recovery (video froze and never recovered after a brief drop):
- Export punktfunk_connection_frames_dropped through the C ABI (the core already
  tracked it for the client keyframe-recovery loop; it was never reachable from
  the ABI clients). Regenerated punktfunk_core.h.
- Apple (StreamPump + Stage2Pipeline) and Android (decode.rs) now poll
  frames_dropped and request a keyframe when it climbs -- the same loss-driven
  recovery Linux/Windows already had. Under infinite GOP the decoder silently
  conceals reference-missing frames, so the decode-error trigger rarely fires.

Apple rumble robustness (worked then went spotty -- DualSense + Xbox):
- Add CHHapticEngine stopped/reset handlers (rebuild on app background / audio
  interruption / server reset) and drop the permanent `broken` latch on a
  transient drive failure; latch only when the controller truly has no haptics.
- Surface swallowed SDL set_rumble errors on Linux/Windows + diagnostic logging.

Verified: cargo build/clippy/fmt --workspace, C-ABI harness, header drift.
Not runnable on this box (verify in CI): Gitea workflows, gradle/Android,
flatpak, Swift/decky.
