Me Here 36989c96de pm-grid: playback-flow auto-advance (rep/end) + MIDI clock out 
Playback flow (rep/end), ported from pico-scroll:
- At each master-bar boundary, after bars*rep cycles the end-action fires:
  end=stop stops; end=next / end=+N advances through the set list.
- The next track is preloaded one bar early (parsed + per-lane durs) into a
  pending slot, then swapped at the exact seam (master lane bar boundary; all
  lanes restart there) for a gapless handoff. load()/manual nav clears pending.

MIDI clock out (default on, so a DAW can slave to the Grid):
- 24-PPQN 0xF8 against the wall clock + 0xFA/0xFC Start/Stop on play/stop (button
  or live-sync). Queued on tx_q as CIN 0xF single-byte packets.

Deferred items needing persistent storage (no CIRCUITPY drive in the Rust build,
needs a flash KV layer - separate milestone): practice log, settings.json,
SLSYNC/LOGSYNC. Also deferred: MIDI clock in, optional piezo.

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
