Me Here dd27d553fe pm-grid: live re-read of programs.json (no reboot needed) 
When the host writes the drive (SCSI Write sets a dirty flag) and the drive has
been idle ~1.5s AND playback is stopped, the loop re-reads programs.json and
rebuilds the set lists (reload_user) -> a dropped file applies without a reboot.

Read-only path (split read_programs_json out of read_user_setlists; the format
flash-write only happens at boot), so no FAT-corruption risk from dual access.

Note on the recommended write path: the device deliberately does NOT write the
shared FAT while the host has it mounted (that corrupts the host cache - same
reason CircuitPython is one-direction-at-a-time). The practice log should instead
go to the editor via LOGSYNC (0x45); settings.json *read* (device read-only) is a
safe follow-up. Documented in docs/rust-port.md.

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
