7c13f519d2 Phase 4 polish: anchor supersede + delete, docs/ideas, field-test scaffolding 
Fixes the sole Round-3 wart: annotating one object from two views now yields
ONE anchor (the single-view fallback is superseded in place by the
triangulation, same id) instead of a sibling pair. Adds DELETE /api/anchors/{id}
(unlinks annotations, 404 on unknown) + a deletable anchor list in the
correction panel. db gains get/update/delete_anchor + get_annotations(event_id).
CR-3 filed (additive). Suite 101 -> 103; frontend build clean; delete UI
verified live (state + DOM + 3D scene stay consistent).

Also: docs/ideas.md (future extensions), plan/ISSUES.md (seeded with the
gemini-2.5-flash retirement, FIXED), plan/status/phase4.md.

e5d6b2c47f Integration (M8 + M9): annotation→3D, camera paths, README, v0.1.0 
M8: POST /api/annotations resolves a bbox to a 3D point (ray → two-view
triangulation / nearest-point / centroid-depth) via lane B's geometry
primitives; correction panel + bbox-drawing UI; resolved anchors render live
in overlays and the 3D scene. CR-2 (additive): annotations.event_id +
PATCH /api/events/{id} + db.update_event.

M9: keyframed god's-eye camera paths (Catmull-Rom position + slerp
orientation, export/import), gizmos, path-mode camera hooks.

Verified: 101 backend tests pass (two-view corner recovery err 0.00000);
frontend build clean; live in-browser M8 triangulation (gap 0.21) + M9 path
(camera on keyframe at t) + M4 sync ~16ms. Cleanup: worktrees removed, debris
stash dropped, pristine demo DB.

ec22cbdf1f Lane C (M4+M5+M6 + timeline): synchronized viewer frontend 
Full frontend built against the synthetic API (no dependence on lanes A/B/D):

M4 — synchronized playback: master clock from performance.now() (never a <video>);
per-video correction via requestVideoFrameCallback (exact mediaTime) with a
currentTime+half-frame fallback — hard-seek >150ms / nudge playbackRate +/-5% 20-150ms /
lock <20ms; out-of-range videos pause+dim; single audio source; dev sync-error overlay.
Timebase mirrors config.py (lib/timebase.js). Verified: seek is exact to 0ms; continuous
inter-video desync 13ms mean / 46ms max.

M5 — 3D viewer: PLY point cloud, per-video camera paths + current-pose frusta, OrbitControls,
snap-to-camera (intrinsics->PerspectiveCamera fov) + free roam. All COLMAP->Three.js via the
frozen lib/pose.js; pose interpolation in lib/poseTrack.js (slerp+lerp of contract inputs).

M6 — anchor overlays: letterbox-correct per-video canvas; anchors projected via pose.js;
behind-camera cull. Projection agrees with an independent pinhole to 1.45e-13 px.

Timeline — colored event markers + legend, hover tooltip, click-to-jump; draggable scrubber.

Phase-3 seams (annotate.js M8, camPath.js M9) left as stubs. No frozen files edited; no new
deps; no change requests.

cf6a6fb2c8 Foundation (M0 + M3 + frozen contracts): scaffold, synthetic fixtures, full API 
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).
