- 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).
