Me Here 8bba218f67 Editor controls for playback flow + close web-side divergences
- docs/playback-flow-test.md: on-device verification checklist for the runtime
  (stop / rep / next / relative-goto / boundary / manual-override cases).
- editor.html + editor-beta.html: graphical "At end" control (loop / next / stop /
  goto ±N) plus a rep-count input in the arrangement panel, wired through
  state.rep/state.end -> currentSetup/currentPatch. Authoring is no longer
  text-field-only.
- src/engine.js: patchToSetup now clamps tempo to [5,300] and defaults to a beep:4
  lane when no lanes are given, matching the firmware. The editors keep their
  "no lanes" hint by checking the raw input for a ':' token instead of parsed lanes.
- fixtures: tempo-clamp-high + empty-defaults-to-beep now pass on both engines.

Suite: 41 pass / 1 known (only the intentional vol/cd host boundary remains).

Track-format conformance tests

Golden-vector suite that pins the track ("program"/"patch") format to a single meaning and checks that both implementations agree:

  • websrc/engine.js
  • firmwarepico-cp/app.py

The spec is docs/track-format.md. Any new implementation (e.g. a Rust engine) must pass the same vectors — that is what keeps "the same groove on the device and in the browser" true.

Run

node tests/run.mjs        # table of pass / known-divergence / FAIL per case
node tests/run.mjs -v     # also print expected-vs-actual diffs for unexpected failures

Exit code is non-zero on any unexpected failure or round-trip (idempotency) break, so it works as a CI gate.

Layout

  • fixtures/track-format.json — the vectors. Each has in (a patch), norm (expected normalized meaning, see spec §5), a status, and optional expectFail listing impls known to differ today.
  • adapters/js_adapter.mjs — loads the real src/engine.js grammar (no copy) and normalizes.
  • adapters/py_adapter.py — extracts the real pico-cp/app.py grammar functions via ast (no copy) and normalizes.
  • run.mjs — runs every vector through both adapters and reports.

Reading the result

  • ✓ pass — implementation matches the spec for that vector.
  • · known — a divergence/feature listed in expectFail; expected, not a failure.
  • ✗ FAIL — an unexpected mismatch (a regression). Investigate.
  • ★ fixed — an impl listed in expectFail now passes; remove it from expectFail.

When you fix a divergence in code, delete that impl from the case's expectFail. When you implement the new playback-flow tokens (rep / end), those cases flip to pass.
