/beats?path= returns bpm, a phase-locked beat grid, downbeats (4/4) and an
honest confidence, using only stdlib + ffmpeg: decode to PCM, log-energy onset
flux, harmonic-enhanced autocorrelation with an octave check, comb phase
search, weighted LS grid refit. 4-min track analyses in ~0.5s, cached after.
Audio in/out now honoured at mux in both scene renders and film beds via one
resolve_audio() path. Found en route: on this ffmpeg build the obvious
atrim/asetpts + amix/apad chain yields an aac stream with ZERO samples, rc=0,
no warning - trim moved to the input side; and the test helper would have
passed on that empty stream, so it now refuses to answer on a window that
decodes nothing.
Tempo bias fixed after orchestrator ground-truth check: decoding at 22050
discarded the HF transient, and since the attack's HF share grew across a file
the surviving LF onset landed progressively later - a per-beat-varying
lateness that reads as tempo error. BEAT_SR now 44100/512 (same 86fps
envelope). Second bug found by sweeping: harmonics outside the lag table
counted as zero and the parabola was fitted on a slope, so 118 BPM read
114.79.
Verified vs independent ground truth: 120.030 vs 120.003 true, 128.020 vs
128.004; worst offset from the true grid 6.0/10.1ms over the whole file (was
45/52ms). Tests now assert whole-file DRIFT, not average BPM, incl. a 200s
track and hftick.wav (16kHz tick over a 60Hz body) which pins BEAT_SR.
18 groups green.

Sequences (ordered shots = scene + in/out + transition) with full validation,
CRUD, and a client-driven film render the server orchestrates: browser renders
each shot through the existing /render/* endpoints, server ffmpeg-concatenates
in order with cuts or xfade dissolves, muxes a film-level audio bed, reaps
after 48h. render.js refactored so there is one frame-post path in the repo
(captureFrames/withRenderSize/begin/end/poll); new web/film.js drives the loop.
Also fixes a pre-existing mux bug: no apad meant short audio truncated PICTURE.
Orchestrator: deploy compose/script now carry SCENEGOD_SEQUENCES + SCENEGOD_FILMS
volumes so shot lists survive a rebuild.
Verified live: demo-two-shot renders one 11.500s mp4 with a genuinely
compositing dissolve; a film built from the M7 templates (street wide ->
dissolve -> closer -> cut -> record store) renders 11.800s at 960x540.
15 test groups green.

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.

templates/ ships with the repo (two-hander-golden-hour, record-store,
empty-stage), GET /templates + /templates/{name} behind the same slug and
path-traversal guards as /scenes; presentation metadata rides in a template
key that validate_scene ignores and toJSON drops, so loading then saving
yields plain scene JSON.
Test group asserts the three list in order, round-trip, traversal/unknown
rejected, write verbs refused, and every template passes validate_scene with
every referenced asset present on disk - the check that stops a rotten
template shipping. 10 groups green.
Verified live: two-hander loads 7 entities, 8s, both performers animating,
cut fires cam1 to cam2 at 4.5s; other two load clean.

Lane A: bone-alias layer so CC_Base_*/Unreal-HumanIK/Rigify/Rokoko/Biped rigs
fold onto the canonical mixamo names — lady.glb pairs 52/102 bones and
retargets (53 tracks) where she previously threw 'missing hips'; mixamo→mixamo
pairing asserted bit-identical. Backdrops gain frustum auto-fit, floor tint
sampled from the plate, and FogExp2 in the plate's colour via a keyable
param. Also caught: _buildLight ran _refreshDefaults before registration, so
scene lights never dimmed the built-in hemi (every preset was washed out).
Orchestrator SYNC-7 fixes (found only by rendering actual frames):
- editor chrome (gizmo/grid/helpers/cam proxies) was baked into output mp4s
- timeline's per-tick rest transform dragged fitted plates out of frame
- fit used the viewport aspect, output renders at its own → letterboxed plates
- plate offset put its top edge on the lens axis → void above centre-frame;
now params.fitAnchor (default 0.75) picks the row that sits at eye level
Verified: 5 suites green; 1280x720 render shows a CC character dancing a mixamo
clip against an edge-to-edge Flow plate with a horizon and matched ground.

Dropping a clip on a non-mixamo rig (lady.glb is a Character Creator export,
CC_Base_* bones) threw inside a fire-and-forget event handler — the rejected
promise vanished and the drop appeared to do nothing at all. Timeline._fail
now logs + toasts via a shared window.sgToast that tlui installs; clipdrop
and direct handlers route through it.
Repro before: two clipdrops fired, only the mixamo one landed, no error.
After: 'clip: retarget: missing hips (mixamorig skeleton?)' toast.
