Me Here 7e2a3b181b pm-grid: live-sync over USB-MIDI SysEx (editor <-> device) 
Port pico-scroll's live-sync to Rust (docs/livesync-protocol.md):
- Reassemble SysEx from incoming USB-MIDI 4-byte packets (by Code Index Number);
  dispatch manufacturer 0x7D frames.
- Version query 0x02 -> 0x03 'G;0.1.0' (editor now identifies the device).
- HELLO 0x40 -> reply FULL; FULL 0x41 -> parse patch + running and adopt it;
  DELTA 0x42 -> apply play/stop/bpm/sel/beat; BYE 0x43 -> disarm.
- Broadcast a DELTA from each on-device input (play/stop, sel, bpm) + a FULL
  heartbeat ~5s (track-format::serialize). Echo-guarded by a boot-derived origin;
  sync_applying flag suppresses re-broadcast while applying.
- Unify all USB-MIDI TX (notes + SysEx) onto one tx_q drained one-per-poll.
- defmt info! on every received op for probe debugging.

Structural lane= edits aren't applied incrementally (arrive as a fresh FULL).

README.md

Rust port — track-format crate (Stage 1)

Pure parse/serialize codec for the track DSL, validated against the shared golden vectors (tests/fixtures/track-format.json) — the third implementation alongside engine.js and app.py. See docs/rust-port.md for the staged plan.

All tooling runs in a container (per the develop-in-container rule):

./rust/run.sh            # cargo test — runs the conformance + idempotency suite
./rust/run.sh cargo build
./rust/run.sh bash       # interactive shell in the crate
