Beat grid consumed from Lane C's /beats: one top-level scene.beatGrid (beats
kept in FILE seconds, effective offset re-derived from the audio clip so
dragging the audio drags the grid and head-trim leaves it put). beat and bar
join the snap selector, so keys, clip and audio blocks, both trim edges, cuts
and the playhead all became musical for free. Grid drawn faint on beats and
brighter on downbeats, suppressed below ~7px spacing. Low confidence still
snaps but says so. Tempo extrapolates past the analysed range.
FILM panel mounts inside #timeline: sequence CRUD, editable shot rows (scene
dropdown, in/out, cut|dissolve + seconds, reorder, delete), live runtime, size
picker, and Render film with per-shot/per-frame progress - gated behind
hasContent() + a confirm that says plainly every shot replaces the open scene,
and locked while running so it cannot be started twice. film.js imported
lazily so its absence cannot stop the timeline mounting.
Verified live: grid 128.02 BPM/35 beats off house128.wav, snapped positions
8-10ms from the true 0.468735s grid across the whole file, bar snap hits a
downbeat, grid survives toJSON->load; FILM lists both sequences with the
server's 11.50s runtime and 3 editable rows.

Lane B: New... in the scene bar fetches the templates API and applies through
a new single apply path (applyScene = stage.applyState + load + preload, now
shared with Load), confirm-before-clobber via hasContent(), thumbs, toasts on
failure. ? overlay documents 24 real bindings read out of the code across
STAGE/TIMELINE/SCENE BAR, ignores ? while typing. Audio head-trim (left edge
eats into the source, one grouped undo). applyScene strips the template key so
saved scenes stay plain scene JSON.
Orchestrator SYNC-9 fix: help overlay dt column was auto-width + nowrap, so
long terms overflowed and the three columns overlapped visually.
Verified live: picker lists 3 (2 thumbs), no confirm when empty / confirms when
dirty, loads 7 entities + 2 cuts with bar refresh, no template key in toJSON,
overlay opens on ? and Escape closes, no hijack while typing. 5 suites green.

- stagestub.js: removeEntity now fires onChange WITH the removed entity (real
Stage contract) so _mirror's getEntity(id)===null removal path is testable.
- timeline.js: setDuration(x) — clamps the playhead, keeps out-of-range keys
(lossless), notifies UI via onLoad. (Reviewed orchestrator's _mirror seam.)
- tlui.js: dur field → setDuration; snap-increment select (frame/0.1/0.25/1s);
keyable-param add via dblclick on a params lane (captures current param
values, skips 'type'/bool descriptors); params lane only when keys exist or
kind is camera/light (no empty lane for characters).
- timeline_test.mjs: _mirror lifecycle (add→keyframe→remove) + setDuration.
Verified in browser (throwaway harness, not committed): dock-adds mirror into
rows, param capture, setDuration clamp+bar refresh, snap-step math.

- timeline.js: onLoad hook (rebuilds rows + refreshes scene bar after load()),
scenegod:clipdrop handler (addClipDrop: block at playhead, out=clip duration,
auto 0.25 fade where it abuts a neighbour), crossfade now fade-IN + fade-OUT
(pre-roll pulls successor start earlier for continuous local time).
- tlui.js: reads tracks from the TIMELINE (authoritative) not the stage copy —
fixes post-load addKey/clipdrop not appearing. Params lanes (per-key color),
camera-cut lane add via dblclick, snap toggle, box-select + multi-drag +
Delete, selection highlight, fade wedge on blocks, grow-to-content height.
- timeline_test.mjs: + onLoad, addClipDrop duration, crossfade weight sum=1.
Verified in browser (throwaway harness, not committed): SYNC #3a/#3b repro
fixed, both clip blocks render, clipdrop/add-key show immediately, cut-add and
box-select multi-drag work.
