feat(alerts): sound byte under Built-in video, and alert audio that reaches the device ...
Creator request: a sound-byte browse + label under Built-in video, with an option to loop the
sound while the clip plays. The video itself is always one pass to completion.
- Source gains AlertAudioPath and AlertAudioLoop, persisted (column + migration + INSERT +
SELECT + reader, the whole chain — that chain is where the blur crashed once).
- The sound byte plays through MediaPlayer on the default output device; MediaEnded re-seeks to
zero while looping, and StopClip kills it so a tail cannot bleed into the next alert.
- The clip's OWN soundtrack moved off the mixer and onto the device as well
(Services/Audio/AlertAudioOutput: one WaveOutEvent + buffered float provider).
Why the move: the creator asked that alert audio — the clip's track or the added sound byte —
appear in the desktop sound bar. Only audio that reaches the default device is picked up by the
WASAPI loopback that feeds both the meter and the stream. The old EnqueueAlertAudio route put the
sound in the stream but left the meter flat and the room silent.
Tests: the sound byte and its loop flag round-trip through SQLite, and a fresh alert layer starts
with no sound byte and no loop. Release 0 warnings.

TASK 9 audio milestone: real stream audio + voice filters + auto-duck + free TRAX music — the mixer now feeds the encoder real audio (ffmpeg reads a Windows named pipe, -f f32le -ar 48000 -ac 2 -i \.\pipe\ytllive_audio, replacing anullsrc silence; explicit -map 0:v -map 1:a via EncoderOptions.AudioPipeName), with honest gains reaching the stream (MicVolume scales mic, GameAudioVolume + mute scale loopback, Func<double> seams on AudioMixer), an always-on pure-C# voice chain on the mic BEFORE the meter and mix (LowShelfFilter 120Hz +4dB → HighShelfFilter 8kHz +3dB → NoiseGate 0.005/hysteresis 0.5 → Compressor 0.5 4:1, all TDF2), AutoDucker (mic RMS>0.02 → loopback ×0.25, attack 0.05/release 0.005), and TRAX free background music (MusicPlayer = MediaFoundationReader → VolumeWaveProvider16 at fixed 0.20 → WaveOutEvent via the new sibling NAudio.WinMM 2.2.1 package; plays to the default device so the existing loopback carries it, ducked with game; footer TRAX button with red/yellow/green status dot, left-click toggles/picks, right-click opens the OpenFileDialog picker, tooltip shows the track name; persisted via schema v9 single-row Music). Build-time deviations from the plan (recorded in ai.md + TASKS.md): WasapiCapture in NAudio 2.2.1 exposes no overridable GetDefaultMixFormat so sources run device mix format and the mixer's TinyResampler normalizes any rate to 48kHz (resampler IS the design); FfmpegEncoder.cs untouched — MainViewModel.StopStream calls _audioMixer.StopLive() (pipe EOF) before the frame pump stops; sound-bar relabelled 'Desktop Audio', IsGameAudioBarVisible = game sound OR music playing. Tests: new AudioPipelineTests (DSP/ring-buffer/ducker/resampler units + the ONE integration test Mix_WithFiltersDuckAndGain_Lands_On_AudioPipe reading real pipe bytes; ring-buffer overwrite bug found + fixed), FfmpegEncoderTests/LayoutStorePersistenceTests updated — 196 tests passing, 0 warnings

Scene strip tile artwork + on-air indicator (creator ruling 2026-10-10). Top-bar tiles now carry their own art: each canonical scene's tile is a per-scene CRT-styled image stored in the internal DB (Scene.ThumbnailAssetId - additive migration, seeded at heal from the creator's five Downloads JPGs via SceneThumbnailSeedPaths), and the preview pane keeps rendering the scene's ORIGINAL background - never the tiles. One shared on-air image (Gemini 4zajyl...jpg) replaces the staged scene's tile and follows the scene swap ('the on-air screen jumps around the top bar as the user swaps scenes'): stored as an Asset BLOB tracked by the OnAirImageAssetId Setting (EnsureOnAirImage, same contract as the alert clip) with MainViewModel.OnAirSeedPath override; RefreshSnapshotsAsync shows it for the staged scene, otherwise thumbnail-or-background art, and a staged Live with no on-air art still falls back to the green placeholder (minis never render live captures). Removed the 6px #22c55e rectangle in PreviewPane's backdrop ('green outline around the preview screen' that surfaced when a scene had no background) - the outer PreviewGlow red border is the real live signal. Doubled the scene-tile labels (FontSize 10 -> 20). Fixed a real bug this surfaced: Save()'s Asset pruner only kept Source/alert-clip rows, so the first save would have DELETED the seeded tile + on-air assets - the keep-set now includes Scene.ThumbnailAssetId and the OnAirImageAssetId Setting. New Settings/Load/Save migrations + SceneThumbnailTests (4 tests: seeded tile in strip, preview keeps original bg, Live-staged tile, no-seed fallback, on-air swap + persistence). 427 pass, 0 build warnings. (Unit: strip tiles + on-air)
