gramps a3dd0791db fix: creator feedback batch Branch 1 — TRAX volume, tooltip, meter boost, slider click, backdrop ...

- TRAX: LocalGain now applies 0.2× factor so music is quieter relative to desktop audio slider
- TRAX tooltip: switched to ToolTipService with Placement=Top to fix z-order in Viewbox overlay
- Mic meter: MeterLevel multiplied by 1.2× before clamping for ~20% higher visual readout
- Volume sliders: click anywhere on track to jump thumb to that position before dragging
- Backdrop: Image Visibility now binds to BackdropVisible; compositor checks IsVisible before blit
- Renamed 'Backdrop' to 'Game Capture' in EnsureBackdrop + test assertions

Audio

TASK 25: master limiter on the live mix (2026-08-15, queued from the TRAX discussion) — the review confirmed two of the creator's three instincts were already satisfied (MediaFoundationReader streams from disk so file size needs no guard; the MusicPlayer 0.20 bed rides the same loopback gain as the game, so music is always exactly 20% of the desktop volume by construction) and found one real gap: AudioMixer.FillAndMix summed mic + loopback with no output ceiling, so hot gains could pass 0 dBFS and clip the AAC encode. New pure Services/Audio/MasterLimiter.cs: -1 dBFS ceiling (Ceiling = 0.891), instant attack per frame (a hot frame is scaled exactly to the ceiling — no overshoot), smoothed release toward unity so loud passages don't pump, gain never exceeds 1. Applied at the end of FillAndMix right before the pipe write. 3 unit tests (trim-to-ceiling, never-boost, recovery) + ONE integration test (MasterLimiter_CapsTheLiveMix_OnThePipe: a 0.95 loopback bed capped to exactly 0.891 on the wire while staying audible). Docs in the same commit: ai.md go-live audio section, Services/index.md new row, TASKS.md TASK 25 record, HANDOFF.md shipped state. Build 0 warnings, 193 tests passing (189 + 4 new)

Encoder

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
