Completes M18 on top of the WIP checkpoint (6a703c3). Three lanes (H/J/K) depend only on
what this freezes.
- synthetic.py: base testsrc2 saturation/brightness-muted so its magenta/cyan colour bars
don't swamp lane H's colour detector; the two moving markers stay the only detectable blobs.
- Frontend (step 6): friendTracks.js stub (never-throws, fx.js pattern) wired into main.js;
hidden #btn-friends + #friends-panel; state.tracks loaded when manifest.has_tracks.
- Tests (step 8): test_tracks_foundation.py (20) — DB helpers, /api/tracks routes, solve
degradation, manifest.has_tracks, frozen OOK protocol + encoders, track_truth shape, the
projection round-trip (rendered pixels back-project to 3D truth, worst err <1e-3 → lane H's
median<0.3 reachable by construction), and a real-ffmpeg render test proving marker A is the
dominant magenta blob after base-muting.
- CR-6: the two sanctioned M18 test-lock edits (test_api manifest key-set +has_tracks;
test_capsule bundle paths +api/tracks). Additive; flagged for integration3 ratification.
Suite: 14 pre-existing files sum to 189 (floor held) + 20 new = 209 passed, exit 0.
Frontend `npm run build` clean. Do NOT merge — coordinator reviews + merges (DIRECTIVES R6 #3).
Recovered by the coordinator session after the foundation3 agent's isolation worktree was
removed mid-run, leaving the work uncommitted; every file independently reviewed, full suite +
build re-run green, then committed. No work redone.

Conflicts resolved: (a) test_phase5_api.py — with lane G's capsule AND
lane E's features/direct all landed, the CLI stub loop is empty, so
test_cli_dispatches_stubs_gracefully is retired with a pointer comment to
the real dispatch coverage (test_capsule.py / test_audio_features.py /
test_director.py); (b) CHANGE_REQUESTS.md — lane G keeps the ratified
CR-4; lane E's entry renumbered to CR-5 and updated for the merged
reality. Merged tree: 189 passed (169 main + 21 lane E - 1 retired),
frontend build clean.

run_features() fills the foundation2 stub: librosa beat/tempo tracking +
onset-strength detection at a 10 ms hop (librosa's default 32 ms grid at
16 kHz quantizes past the +/-50 ms acceptance bound), tempo from the median
inter-beat interval, times mapped to t_global via the frozen timebase
helpers. Degradation per house style: missing videos/WAV -> summary with
note, nothing written; silent/short/beatless audio -> valid-empty
beats.json, never a crash.
Acceptance (test_audio_features.py, 7 tests): synthetic 120 BPM grid
recovered — tempo 120.0 (+/-2 required), worst beat 30 ms off grid
(+/-50 required); the three ground-truth bangs appear as strong onsets;
silence/short/missing all degrade cleanly; CLI dispatch end-to-end.
CR-4: minimal stub-era assertion updates in test_phase5_api.py (CLI stub
loop shrinks to capsule) per the approved CR-1 precedent — see
plan/CHANGE_REQUESTS.md.

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.

Fills events_ai.py against the frozen M7 contract:
- detect_candidates: RMS x spectral-flux, local-max over a 10s neighborhood,
>=P90, with an AC-RMS (std) silence/DC floor so flat audio yields no events.
Matches the fixture ground-truth pulses [3,10,17] within ~0.02s (<0.5s).
- GeminiClassifier (native video), ClaudeClassifier (claude-opus-4-8,
messages.parse, adaptive thinking, no temperature), LocalClassifier
(OpenAI-compatible, 6 frames, 1 retry). SDKs imported lazily.
- get_classifier: FESTIVAL4D_CLASSIFIER selection; unconfigured -> None
(candidates-only, logged).
- prepare_inputs: ffmpeg 3s clip (<=720p, audio kept) + 6 JPEGs (<=768px).
- run_events: reference-audio detect -> classify (insert-once in final state,
since db.py has no update-event helper); per-candidate exception isolation;
whole-track replaces machine events (keeps user edits), windowed is additive.
test_events_ai.py: candidate-vs-ground-truth (no ffmpeg/API), stub-classifier
orchestration, exception isolation, degradation, provider selection, silence.
Also updates the now-obsolete api stub test (test_detect_events_endpoint) to the
real M3 {result, events} shape; frozen api.py unchanged (see CR-1). pytest: 90 passed.
