A third implementation of the track DSL alongside engine.js and app.py, validated against the same tests/fixtures/track-format.json: - rust/track-format/: pure parse()/serialize() codec (std + alloc for now; no_std is a later refinement). Ports the app.py/engine.js semantics exactly — grouping, subdivisions, swing, ghost, polymeter, euclid, GM note-number aliases, unknown->beep, default groove (group-start accents), tempo clamp, empty->beep, and the playback-flow tokens (rep/end/relative-goto). Carries vol/cd too, so it's the most spec-complete of the three. - tests/conformance.rs: the Rust adapter — reads the shared fixtures, asserts each case's normalized form (number-tolerant deep-equal) + serialize idempotency. - rust/Containerfile + run.sh: Rust toolchain in a container (mirrors hardware/eda/), with the thumbv8m.main-none-eabihf target for the eventual RP2350 firmware. Never on the host. Verified: ./rust/run.sh -> cargo test -> conformance + idempotent both pass. docs/rust-port.md Stage 1 marked done.

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
