F12 — Hero-component spine is a templating anti-pattern. The first
atelier proof (alexandria-fire) leaned on a single candle as scaffolding
under every scene with different text below — same hero, different
caption — which is exactly the "branded slides" pattern atelier was
supposed to break. The signature device is meant to appear in ONE or
at most two beats (typically the climactic moment), not as the visual
scaffolding of every scene. Each scene must earn its own composition:
a different primary visual subject, a different scale, a different motion
register. Doctrine added as step 1.5 in skills/meta/bespoke-composition.md
("Plan each scene as its own composition") plus a reviewer
scene_distinctness gate enforced at compose stage — the reviewer samples
one representative frame per scene and refuses to pass if two or more
scenes share their primary visual subject.
F9 — Captions/on-screen-text dedup. When a SerifLine reads the script
verbatim AND auto-captions emit the same text, the piece looks amateurish
even when the rest is beautiful. Rule added under engine mechanics: decide
once per piece whether captions add meaning (numbers, names, translations,
attributions) or are accessibility subtitles echoing narration — never
both for the same content. Reviewer gate at compose stage compares active
caption text against on-screen text in the same time window.
Both gates are CRITICAL; the publish-stage check was updated to expect
six (was four) resolved atelier findings.
Self-audit of alexandria-fire under the new rules: 4 of 5 scenes share
the candle as their primary visual subject — would now flag CRITICAL
scene_distinctness and require re-planning. (Re-author the piece in a
follow-up; the doctrine is the deliverable here.)
Introduce a hand-authored, project-local Remotion render path that bypasses
the cut-schema and the stock scene-type registry, for hero/bespoke videos
that must look distinct from one another.
- video_compose: composition_mode="atelier" (or renderer_family="bespoke")
routes to _render_via_atelier, which renders a project-local entry under
remotion-composer/projects/<slug>/ with an optional per-project public_dir
(skips copying the bloated shared public/). No cut-schema, no stock registry.
- skills/meta/bespoke-composition.md: routing skill — art direction
(visual-style) -> motion principles (Disney 12) -> engine mechanics
(remotion-best-practices + stock components read only as a mechanics codex)
-> atelier render. Doctrine: reuse engine knowledge, never creative components.
- AGENT_GUIDE: "Composition Authoring Mode" (templated vs atelier); default
atelier for hero work; scene-type catalog reframed as a mechanics codex.
- animation-runtime-selector + INDEX: authoring-mode-first pointers.
- base_tool.run_command: decode subprocess output as UTF-8/replace (Windows
cp1252 crashed the reader thread on Remotion's Unicode progress output).
- .gitignore: remotion-composer/projects/ (throwaway bespoke compositions).
