Record gesture: hold BOTH ⌘ → a charging count-in (jeffrey-voiced 3·2·1 via /api/say + rising white-noise hush + brightening red glow) → tape rolls → play (keys light red) → Escape dumps the take. Right ⌘⌘ still = play/focus, left ⌘⌘ = Shapedown. Each take is wrapped into its own DMG 'record release' on the Desktop: our AppIcon as the volume icon, the take's WAV inside, and generative album-art (bold length, random hue per take) on the .dmg file. Audio is the full processed stereo mix (panning/dynamics/space/echo), dead-air trimmed both ends, peak-normalized to ~-1 dBFS. Synth-only — no mic prompt. Fixes: sample-rate converter went terminal after one buffer (endOfStream) so only ~65ms captured at 96kHz — now uses .noDataNow to keep filter state continuous (no dropout, no boundary pops). 4-channel WAV format needs an explicit discrete channel layout (the channels: initializer returns nil). Adds .mbscore auto-perform test harness (--mbscore <path>) + tape-test.mbscore so the whole record→trim→normalize→art→DMG pipeline runs hands-free. Also: shapedown corner-wrap around vertex dots, single-weight stroke, evaporate-on-lift + click-to-commit + close bloom, one-group compositing.
