Adds a transcript_comparison check to VideoCompose._run_final_review
that word-diffs the whisper/whisperx transcript against script.txt and
fails loudly when the TTS engine literally voiced punctuation tokens
(dot, dots, ellipsis, comma, dash, hyphen, period). Chirp3-HD did this
to ellipses in a production run and it slipped past review; now it
cannot.
Also corrects the "tiny background video" gotcha in
skills/core/hyperframes.md. After six renders of blaming HyperFrames
CSS, the real root cause was 640x360 Pexels sources combined with a
fit-and-pad pre-transform — HyperFrames was rendering the letterboxed
input faithfully. Gotcha now walks through the ffprobe diagnostic and
the scale-to-cover fix, and keeps the wrapper-div pattern for the
right reasons (aspect mismatch handling, not framework bug workaround).
Four regression tests cover the new check: punctuation-leak detection,
clean-audio false-positive guard, graceful skip when inputs missing,
and always-present transcript_comparison section.
Separates creative grammar (renderer_family) from technical engine
(render_runtime) so HyperFrames can stand alongside Remotion as a
first-class runtime instead of masquerading as a Remotion sub-case.
Locks runtime choice at proposal stage and enforces it end-to-end: the
schemas require it, video_compose routes by it, the reviewer fails
closed on silent swaps, and a parametrized contract test walks every
pipeline manifest to ensure each planning-stage skill explains the
conversation to the user. Adds hyperframes_compose (scaffold/lint/
validate/render/doctor/add_block), a playbook -> CSS style bridge, and
vendored HyperFrames Layer 3 skills from commit d291358, pinned via
PROVENANCE.md for future re-sync. Final_review now records
render_runtime_used and runtime_swap_detected so compose lies are
catchable after the fact.
All of these changes came out of running the P1 and P2 documentary-montage
audits end-to-end and watching specific things break. Grouping them into
one commit because they share a theme: making the corpus builder and its
stock source adapters robust enough that a real brief can produce a
real corpus without special-casing.
corpus_builder.py + new clip_cache.py + test_clip_cache.py
Phase 1 of the shared-corpus architecture. Adds
~/.openmontage/clips_cache/ — a process-safe, LRU-evicted cache of
downloaded clip files keyed by clip_id. Before each candidate download,
corpus_builder asks the cache whether the bytes already exist on disk
from a previous run; on a hit it hard-links (or copies on cross-drive)
the blob into the caller's corpus dir and skips the network fetch. On
a miss it downloads as usual and ingests the fresh file. Motivation:
re-running the P1 audit after every tool fix was re-downloading gigs
of archive.org footage that had already been fetched in the prior run.
Cache faults never block the pipeline — they degrade gracefully to
normal downloads. The cache bubbles counters into the corpus_builder
return payload so the production report can show hit/miss/bytes-saved.
Default 20 GB cap, overridable via OPENMONTAGE_CACHE_MAX_GB.
Full test coverage: try_link, ingest, stats, LRU eviction, manifest
persistence, lock behavior. 23 tests, tmp_path-scoped.
stock_sources/archive_org.py
1. Three-strategy query cascade (phrase_prox_10 → distinctive_and →
distinctive_or). Motivation: natural-language documentary queries
against archive.org Solr were zeroing out — "1950s family watching
television" returned 0 hits because Solr's default multi-term AND
over-intersects. Walks strict to loose and returns the first
non-empty strategy. Stop words, source hints ("prelinger",
"archive", "footage"), and year tokens ("1950s") are excluded from
the distinctive-token picks since they don't correlate with
Prelinger title tokens.
2. 150 MB per-rendition size cap. archive.org routinely hosts
multi-hundred-megabyte h.264 masters and one 2 GB Prelinger item
poisons corpus build wall-time and disk. Within a format bucket
we now pick the largest rendition under the cap; if nothing fits
we fall through to the next format rather than dropping the item.
3. 180 s default max-duration ceiling when the caller hasn't set one
— archive.org is the only source that routinely hosts feature-
length material and a naive fan-out pulls them into corpora that
only ever want a few seconds per clip.
stock_sources/wikimedia.py
Parallel 3-strategy cascade (full → top2_or → single_best). Motivation:
Commons CirrusSearch also defaults to AND across multi-word queries;
our first P2 diagnostic pass returned 0 video results for 10/10
queries. Same stop-word / source-hint / year-token stripping as
archive_org so the two adapters stay symmetric.
test_stock_source_adapters.py
Rewrote the wikimedia query-builder tests against the new cascade
API. Added coverage for multi-word fallback + source-hint/year
stripping.
video_compose.py
Two small fixes for the Remotion renderer on Windows:
1. Resolve output_path to absolute before invoking the CLI so the
binary can write wherever the caller asked regardless of cwd.
2. Pass cwd=composer_dir to run_command so npx can find the local
Remotion binary under node_modules/.bin. Without this, Windows
npx returns "could not determine executable to run" because it
resolves .bin relative to the process cwd rather than the
script's parent.
test_01_tts.py (ElevenLabs), test_02_image_gen.py (DALL-E + FLUX),
and test_03_music.py (ElevenLabs Music) were burning ~$0.44 per run
against live API keys. These were run repeatedly and exhausted the
ElevenLabs starter plan quota (30K characters).
Implements the 2026-04-02 transformation spec (Phases 1-8) and fixes all
critical bugs found during 5-pipeline E2E testing.
Governance & Decision Intelligence:
- Pipeline-specific stage order in checkpoint (replaces global STAGES list)
- Provider scoring engine (lib/scoring.py) with 7-dimension weighted ranking
- Decision log artifact enforced at proposal/idea stage across all 10 pipelines
- Delivery promise classifier prevents silent motion-to-still downgrades
- Structured shot language in scene_plan schema (camera, lens, lighting, DOF)
- Variation checker and slideshow risk scorer block samey output before render
- Creative intake, capability extension, and creative-intake meta skills
- Final self-review artifact with 5 mandatory checks before presenting output
- Source media review contract for user-supplied footage
Render & Theme System:
- Remotion AnimatedBackground now derives colors from playbook (no more hardcoded
dark blue fintech gradient on every video)
- video_compose builds custom ThemeConfig from playbook YAML colors/fonts —
custom playbooks flow through to Remotion automatically
- Explainer component wires theme to all child components (charts, cards, etc.)
- resolveAsset() handles absolute paths on Windows/Unix via file:// URIs
- RENDERER_FAMILY_MAP synced with actual Remotion compositions
Critical Bug Fixes:
- Windows npx subprocess: run_command() resolves .cmd wrappers via shutil.which()
- Silent renderer downgrade: Remotion failure now returns explicit error with
options instead of silently falling back to FFmpeg
- .env inline comment parsing strips trailing # comments from API keys
- concat_path UnboundLocalError in video_compose finally block
- audio_mixer and showcase_card capture=True kwarg bug
- Selector estimate_cost() calls fixed (_select_tool -> _select_best_tool)
- asset_manifest schema expanded with provider, license, subtype fields
- screen-demo subtitle_gen moved from required to optional tools
- Duration drift detection in post-render final review (>25% warns)
Two new provider tools following the BaseTool pattern with auto-discovery:
- google_imagen: Imagen 4 image generation via Generative Language REST API
- google_tts: Google Cloud TTS with 700+ voices across 50+ languages
Both share GOOGLE_API_KEY env var. Selectors auto-discover them — no
selector code changes needed. Docs and contract tests updated.
