TASK 8 meter scaling: +10 dB input amplification in AudioLevelMeter.ToDisplay so the meters use the full bar — speech peaks (~0.2 RMS, -14 dBFS) read ~0.93 (red zone) and normal speech (~0.05, -26 dBFS) ~0.73 (yellow) at maxed volume, instead of hovering at the red edge; ≤0.001 linear still reads zero so the meter never idles on background noise; one knob shared by the mic bar and the game bar (× MicVolume gain-on-noise untouched); tests updated + new ToDisplay_Pushes_Speech_Peaks_Into_Red_At_Maxed_Volume — 171 tests passing, 0 warnings

+- **TASK 8 (new, after TASK 7 shipped):** `AudioLevelMeter.ToDisplay` gained **+10 dB input
+  amplification** so the meters use the full bar — speech peaks (~0.2 RMS) now read ~0.93 (red)
+  and normal speech (~0.05) ~0.73 (yellow) at maxed volume; ≤0.001 linear still reads 0 (idle
+  never shows noise). One knob shared by the mic bar and game bar; `× MicVolume` untouched.
+  Tests updated + new `ToDisplay_Pushes_Speech_Peaks_Into_Red_At_Maxed_Volume`. **Uncommitted**
+  (pending user review): `Services/Audio/AudioLevelMeter.cs`, `ytLive.Tests/AudioMixerTests.cs`,
+  `ai.md`, `Services/index.md`, `ViewModels/index.md`, `TASKS.md`, `HANDOFF.md`. Meter tests:
+  7/7 passing, build 0 warnings.
 - **This session (TASK 7 — UI polish batch, gramps's 6-point review):**
   1. **Scenes list cleaned:** the per-row edit/trash/visibility icons and the inline
      rename TextBox are gone. Scenes are pure selection rows; `IsHidden` stays
