One-line story -> stage brief (parse_stage) -> creative-brain plan -> build via scene_director -> scene-qc inspection/fix loop -> report + screenshots. Reuses the in-repo creative-brain and scene-qc packages; ships a dry-run in-memory executor and tests, an empty examples/ai-stage host, an openCode subagent, and the AI场景导演 integration doc that doubles as the agent-queryable scene-director spec.
