VAAPI decode stays; what changes is who touches the YUV. The direct path hands
the NV12 dmabuf (tiled AMD modifier since Mesa 25.1) to GdkDmabufTexture, and
GTK's tiled-NV12 import renders corrupt/gray/washed-out on the Deck. Moonlight
and mpv are clean on the same box because they import the dmabuf into their own
EGL context and convert with their own shader — video_gl.rs is that
architecture for the GTK client: per-plane EGLImages (R8 + GR88, modifier
passed through) → our YUV→RGB shader (matrix/range from the stream's CICP
signaling, unit-tested) → RGBA texture in a GdkGLContext-shared context →
fence-synced GdkGLTexture. GTK composites plain RGBA; no YUV negotiation, no
compositor CSC.
The Deck's decoder default flips back to hardware (the software stopgap is
gone); desktops keep the direct dmabuf path (offload/scan-out eligible).
PUNKTFUNK_PRESENT=direct|gl overrides either way. New failure ladder: GL
converter init failure or a convert-error streak raises a shared flag and the
session pump demotes the decoder to software with a keyframe re-request — the
same mechanism also closes the old silent-black-screen gap where a rejected
dmabuf import had no recovery at all.

Each client learns a host's MAC from the mDNS `mac` TXT while it's awake, persists it on the saved-host record, and — when reconnecting to an offline host — sends a magic packet before connecting, plus an explicit "Wake host" action. Apple wraps the C-ABI; linux/windows call the core fn directly (linux also gains a --wake CLI mode); android via a new nativeWakeOnLan JNI export (the mDNS browse record gains a 7th mac field); decky shells out to the linux client's --wake before launching the stream.
iOS/tvOS need the managed com.apple.developer.networking.multicast entitlement (pending Apple approval), so the wake path + UI are gated off via PunktfunkConnection.wakeOnLANAvailable and the entitlement is commented out — keeping iOS/tvOS releasable. MAC-learning stays active on every platform so it lights up the moment it's ungated. macOS works today.

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).

- 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.

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.
