Creator: "why is there no meter for when trax is playing?" Routing answer: TRAX rides the desktop loopback, so it already moved the GAME ladder — there was no separate TRAX signal in the mix. But that ladder cannot answer the question a deaf creator actually has: "is the music producing sound at all?" The play glyph cannot either — an open file with a dead decoder still reports Playing. So the player now measures its own output: \`MusicPlayer\` wraps the volume stage in an NAudio \`MeteringSampleProvider\` and exposes \`Level\`; \`ITraxPlayer.Level\` keeps the fake honest. The VM maps it through the same display scale (\`TraxMeterFraction\`), zeroed when not playing, and the TRAX bay carries a 24-segment ladder above its fader. This reverses my earlier "no ladder, nothing honest to show" — the honest thing arrived with a real measurement. TraxBayTests flipped accordingly (it now asserts the ladder AND its source).
