What now works: - M0 scaffold: pyproject (all spec deps), uv/py3.12 env, `python -m festival4d` CLI registering synthetic|ingest|sync|reconstruct|events|serve. Vite hello page. - Synthetic fixture (synthetic.py): 3 shifted-audio videos (offsets 0/+1370/-842 ms), camera-arc poses, stage point cloud -> points.ply, seeded events + anchors, ground_truth.json. `python -m festival4d synthetic` populates data/ + DB. - DB schema exactly per spec §2 (db.py) + CRUD helpers all lanes use. - M3 API (api.py) full against synthetic data: manifest/poses/pointcloud/anchors/ events/detect/annotations; Range-capable video serving (206 verified); CORS for any localhost origin. - Frozen geometry contract: geometry.colmap_to_threejs (M5 math) + unit test (3 known vectors, random round-trip, scipy oracle); mirrored frontend/src/lib/pose.js with identical POSE_TEST_VECTORS. Lane-B stubs: slerp_pose, ray_from_pixel, triangulate_rays, nearest_point_on_ray. - Classifier contract (events_ai.py): MomentClassification model + MomentClassifier protocol + Gemini/Claude/Local provider stubs. - Lane-owned modules stubbed with final signatures (ingest, audio_sync, frames, sfm, events_ai); cli/api catch NotImplementedError and degrade gracefully. - plan/CHANGE_REQUESTS.md created; plan/status/foundation.md updated. Acceptance: pytest 24 passed; serve endpoints verified via curl + browser (video seek, manifest fetch cross-origin, pose.js self-test, 0 console errors).
