From 8f2a488c51ebab5afc52fa936ae6c8ee3db93db4 Mon Sep 17 00:00:00 2001 From: type-two Date: Fri, 17 Jul 2026 21:18:53 +1000 Subject: [PATCH] =?UTF-8?q?foundation3=20(M18):=20complete=20Friend-Tracks?= =?UTF-8?q?=20foundation=20=E2=80=94=20fixture=20ground=20truth,=20contrac?= =?UTF-8?q?ts,=20stubs?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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.
