The parallel agent's full session, committed now that it's solo: - Grammar: flam/drag/roll ornaments (f/F d/D z/Z, per-lane orns channel) across src/engine.js, pico-cp/pico-explorer/pico-scroll app.py, pico/main.py, rust/track-format, + golden vectors / conformance (tests/, rust/track-format/tests). - Live-sync deep-sync: SysEx 0x44 SLSYNC + 0x45 LOGSYNC (docs/livesync-protocol.md, src/livesync.js). - PM_E-2 notation: web engine (pm_e-2.html, build/deploy/index/embed wiring) + Rust device port (pm-ui draw_notation rewrite + LaneView.groups, pm-kit ViewMode, uisim notesim). Verified: node tests/run.mjs 47 pass / 1 known; ./rust/run.sh green; pm-kit firmware + uisim compile.
