The rest of the client-gaps handoff, plus what a parity sweep surfaced: * Every whole-file settings save rebases on the file first — the GTK dialog close and its two speed-test apply arms, the Windows per-control commit, the console screen. The file has five writers and no merge (profiles.rs documents the debt); saving a shell-lifetime snapshot silently reverted whatever another writer stored meanwhile, most visibly the spawner-persisted match-window size (item 4). * Windows honors the Speaker/Microphone picks: `audio_wasapi` grows endpoint enumeration (on its own MTA thread — UI threads are STA) and resolves PUNKTFUNK_AUDIO_SINK/SOURCE as endpoint ids, falling back to the default when the picked device is gone; the settings page gets the two rows (defaults scope, "(not detected)" like the GPU row). `speaker_device`/`mic_device` stop being Linux-only fields (item 5). * A punktfunk:// link with `launch=` opened a plain desktop session on Windows — the id was parsed, validated, planned, and dropped at the last hop. It now rides `initiate_launch` (plus a waking variant for the dial-first path). Linux always forwarded it. * The console UI offered "VAAPI" on Windows — a dead option there that also hid d3d11va, the actual Windows hardware path. The decoder list is per-OS now. * The Windows gamepad picker learns "Steam Deck" (the GTK picker had it; the host-side pad has always existed). * Doc fixes: gpu.rs named a nonexistent env var (PUNKTFUNK_ADAPTER → PUNKTFUNK_VK_ADAPTER), and session/Cargo.toml claimed video decode is Linux-only while explaining what the ARM64 leg drops.
