Review findings from PR #333:
P1: _download_via_uri assumed output_video.uri is always files/<id>.
The API can return a full resource URI or a ready-made
.../files/<id>:download?alt=media download URL, which produced an
invalid poll path with a second :download appended. New
_file_id_from_uri() extracts the bare id from every documented shape;
regression tests cover the full-URL form plus a parametrized matrix of
URI shapes.
P2: docs/PROVIDERS.md still described the Google key as TTS + Imagen
only. The shared-key section now covers gemini_omni_video (model id,
~$0.10/sec pricing table, paid-tier-only, edit-turn billing note), and
the env snippet, provider-to-tool mapping, and capability coverage
tables include the new provider.
End-tag now composited over final body footage (ProRes 4444 with alpha)
instead of concatenated as a black card. Updated idea-director,
edit-director, compose-director, and pipeline manifest with overlay-first
instructions. Default Google TTS voice changed from Neural2-D to
Chirp3-HD-Orus across tool code and docs.
- New: Higgsfield video provider with multi-model routing (Kling 3.0, Veo 3.1, Sora 2, WAN 2.5, Soul Cinema) and Soul ID character consistency
- Updated: Runway provider with gen4_aleph and gen3a_turbo models, proper pixel-ratio mapping, probe_output, watermark param, RUNWAYML_API_SECRET env var support
- Docs: Updated provider counts (12→13), tool counts (51→52), added Higgsfield setup/pricing sections across README, AGENT_GUIDE, ARCHITECTURE, and PROVIDERS
Remotion is the key fallback when no video gen APIs are configured —
the agent generates images and Remotion animates them into video.
Updated README Composition section and added full Remotion section
to PROVIDERS.md with component list and activation rules.
