- replay mode: scrub a completed run from checkpoint history + event
timestamps — stage rail rewinds, script/storyboard/renders appear at
their real moments, generating shimmer replays; ~20s full-run playback
- stage history_entries exposed in BoardState (powers replay + versions)
- entrance choreography plays on first paint only (not on SSE refreshes)
- live-run fixes found by driving a simulated production against the
board: null rendered by native append, activity ticker showing closed
starts as running, scene-id label handling for 'scene-N' ids
- scripts/backlot_simulate_run.py: drives a fake production through the
REAL contract (init_project, in_progress heartbeats, gated
awaiting_human -> approved, per-scene events, growing manifest) —
live-board verification + demo driver
- backlot/README.md
Closes the remaining three atelier audit gaps.
F1 — atelier projects live under repo-root projects/<slug>/ (the
established OpenMontage convention), not under remotion-composer/.
_render_via_atelier now auto-stages source files into
remotion-composer/projects/<slug>/ via mtime-skip copy when the entry
isn't already under the composer tree. Originally tried a directory
junction, but webpack walks up from the entry's REAL location to
resolve node_modules — junctions get dereferenced and module resolution
fails. Copy keeps source-of-truth under projects/, is invisible to the
user's project view, and is cheap (typical project is a few small .tsx
files). Output stays wherever output_path says. effective_entry is
returned in tool data for transparency.
F3 — scripts/scaffold_atelier_project.py generates the engine
boilerplate (index.tsx / Root.tsx / Composition.tsx / art-direction.md /
props template / README) ONLY. No creative content emitted — the
Composition.tsx is a deliberately blank black placeholder with prominent
TODOs. This removes the friction that nudged agents back to templated
mode while making it impossible to ship the scaffold unauthored (review
correctly flags black frames / silent audio as 'revise'). Verified
end-to-end: scaffold → render → review fires the right warnings.
F5 — schemas extended to know about atelier:
- decision_log: 'composition_mode' added to category enum.
- proposal_packet.production_plan: composition_mode + art_direction.
- edit_decisions: composition_mode + bespoke{entry, composition_id,
art_direction, props_path, public_dir, scale, crf, concurrency}.
- final_review.checks: 'atelier' block (stock_reuse_detected,
offending_imports[], art_direction_declared, art_direction).
- final_review.recommended_action: 're_author' added.
- final_review.transcript_comparison: allow null word_accuracy /
transcript_matches_script (pre-existing latent bug surfaced here).
Both pass and fail shapes of the atelier render's final_review now
validate against the updated schema.
