FEATURES (from a 5-lens audit: UX friction, feature gaps, bug hunt, visual
quality, discoverability):
- ACES filmic tone mapping + per-preset exposure. grammar.js runs physical sun
intensities of 1.2-3.4; with NoToneMapping every lit face clipped to white and
a warm key rendered neutral. Single biggest look win in the app.
- Real shadows: PCFSoft, a shadow box fitted to the scene's bounds, and plates
that no longer double as the shadow catcher (dedicated ShadowMaterial).
- A Render button in the scene bar. finalRender had ZERO callers - the app's
deliverable was console-only.
- Save actually saves the stage you built (gizmo moves, inspector edits), and
Save/Load stop lying about what happened.
- 2x supersample + lanczos downscale; correct bt709 tagging and faststart.
- Frame guide, camera-from-view, dock counts, delete confirmations.
DEFECTS FOUND BY ADVERSARIAL REVIEW AND FIXED (all reproduced first):
- BLOCKER: save wrote the playhead pose over the authored rest transform of
keyed entities, so every save produced a different file.
- renders were converted with the bt601 matrix while tagged bt709.
- deleting an unkeyed camera stranded its cut -> scene 422s forever.
- corner plates showed one photo at two exposures across the fold.
- exposure was advertised as keyable but nothing keyed it, so a second lighting
preset permanently poisoned the first.
- the audio pre-flight could never fire (FastAPI does not route HEAD -> 405).
- the two render buttons were not mutually exclusive.
- frame guide letterboxed a narrow viewport that the render does not crop.
ORCHESTRATOR (round 3): dangling camera cuts are pruned in Timeline.toJSON and
skipped by cutCameraAt, rather than trying to keep every undo history clean -
deleting a camera spans Stage (no undo) and Timeline (undo), so any older entry
can resurrect a cut for a dead camera. Verified against the real validator.
Also replaced a VACUOUS test that drained a stack whose only entry was a seeded
no-op; timeline_test.mjs now replays both real histories and discriminates.
Verified: 4 JS suites + 23 server groups + render client green; blocker repro
now preserves the authored rest at every playhead position; save round-trips
200 with zero dangling cuts; zero console errors.
