// Anchor manager & friend tags (spec M13, lane F).
|

//
|
//
|
||||||
// Pre-wired by foundation2: the hidden ⚓ toggle (#btn-anchors) and the empty #anchor-panel
|
// A collapsible panel (pre-wired container #anchor-panel, toggle #btn-anchors) listing every
|
||||||
// container in index.html, this module's import + init() call in main.js, the hooks
|
// anchor in state.anchors: color dot (recolor), label (rename), jump-to (scene3d.focusOn),
|
||||||
// `scene3d.focusOn(x, y, z)` (jump-to) and `PATCH ${state.apiBase}/api/anchors/{id}`
|
// delete. Mutations go through PATCH/DELETE ${state.apiBase}/api/anchors/{id}; after any
|
||||||
// {label?, color?} (rename/recolor), plus DELETE /api/anchors/{id} from phase 4.
|
// mutation we update state.anchors and emit("anchors-changed") so scene3d + the video
|
||||||
|
// overlays refresh (main.js wires that event to scene3d.refreshAnchors; overlays read
|
||||||
|
// state.anchors every frame).
|
||||||
//
|
//
|
||||||
// When implementing: unhide the button, set `ready = true`; build the collapsible list
|
// ＋ Tag (friend tags): drives the FROZEN M8 annotation flow WITHOUT an event.
|
||||||
// (color dot, label, jump-to, rename, recolor, delete) from state.anchors; after any
|
// annotate.js was written null-event safe on purpose: startAnnotateMode() only needs the
|
||||||
// mutation update state.anchors and emit("anchors-changed") so scene3d + overlays refresh.
|
// registered cells, and _submit POSTs /api/annotations with event_id: null, which the backend
|
||||||
// The ＋ Tag flow reuses the M8 bbox-annotation flow WITHOUT an event (annotate.js is
|
// resolves to an INDEPENDENT anchor ("Annotations with no event stay independent").
|
||||||
// frozen — drive it, don't edit it) and names the resulting anchor.
|
// Flow: prompt for the friend's name -> annotator.close() (clears any currentEvent) ->
|
||||||
// Capsule mode: give every MUTATING control the `write-ui` class — body.capsule hides that
|
// annotator.startAnnotateMode() -> the user drags a bbox over the friend on any video ->
|
||||||
// class globally (contract #5); the read-only list + jump-to stay available.
|
// the resolved anchor arrives via emit("anchors-changed", anchor) -> we PATCH the pending
|
||||||
|
// name + a palette color onto it and stop annotate mode. Esc (or ＋ Tag again) cancels.
|
||||||
|
//
|
||||||
|
// Capsule mode (contract #5): every MUTATING control carries class="write-ui" so a baked
|
||||||
|
// bundle hides it; the read-only list + jump-to stay available.

# Status — lane-F (social & fun UX: M13 anchor manager + friend tags, M14 photo mode, M15 moment FX)
|
||||||
|
|
||||||
|
## Round 1 — 2026-07-17 — STATUS: ready_to_merge
|
||||||
|
|
||||||
|
**Directives acknowledged:** Round 4 of plan/DIRECTIVES.md (phase 5b begins; foundation2 merged; worktree rule followed — this lane ran in its own worktree on branch `lane/f-social`).
|
||||||
|
|
||||||
|
**Ownership kept:** only `frontend/src/anchorPanel.js`, `frontend/src/photoMode.js`, `frontend/src/fx.js`, and this file were touched. No frozen file edited; no CHANGE_REQUESTS entry needed.
|
||||||
|
|
||||||
|
**Friend-tag design choice (M13):** the ＋ Tag flow DRIVES the frozen M8 annotator without an event — no workaround needed. Rationale: `annotate.js` is null-event safe by construction (`startAnnotateMode()` only needs the registered cells; `_submit` POSTs `event_id: ev ? ev.id : null`; every panel-content access is optional-chained), and the backend explicitly supports it (`api.py`: "Annotations with no event stay independent (each makes its own anchor)"). Flow: prompt for the friend's name → `annotator.close()` (clears any currentEvent) → `annotator.startAnnotateMode()` → user drags a bbox over the friend on ANY video → the resolved anchor arrives via `emit("anchors-changed", anchor)` → anchorPanel PATCHes the pending name + a palette color onto it and stops annotate mode. Esc or ＋ Tag again cancels. This reuses the real M8 ray-cast/nearest-point resolution (friends land ON the point cloud), keeps annotate.js untouched, and is one drag for the user.
|
||||||
|
|
||||||
|
**Acceptance checklist — ALL verified live** (worktree servers: backend :8010 with an isolated copy of the synthetic data — the main project DB was never touched — + Vite :5175 with `VITE_API_BASE`; browser = Claude Code Browser pane, loop driven with the `__f4d` pump per pitfall #2 where noted):
|
||||||
|
- [x] M13 create → rename → recolor → jump → delete roundtrip live: ＋ Tag with prompt "Zoe" + real 35×30 px drag on cam0 → anchor id 5 `{label:"Zoe", color:"#7dffb0"}` created via the frozen annotator; ✎ rename → `"Zoe B"`; color input change → `#ff00aa`; label-click jump → `scene3d.controls.target == (1.60, 0.00, -6.50) ==` anchor pos exactly, follow-cam detached; ✕ delete → state.anchors 5→4, row removed.
|
||||||
|
- [x] M13 labels visible in 3D + video overlays: screenshot shows the pink "Zoe B" sphere+label centered in the 3D scene after jump AND "Zoe B" x-ray markers on cam0 + cam2 overlays.
|
||||||
|
- [x] M13 anchors survive reload: full page reload → anchor id 5 still `{label:"Zoe B", color:"#ff00aa"}` from GET /api/anchors.
|
||||||
|
- [x] M13 capsule mode: with `body.capsule`, tag/rename/delete/recolor controls hidden (`offsetParent === null`), panel + list + jump-to remain visible.
|
||||||
|
- [x] M14 PNG ≥3840 wide, aspect preserved, no helpers: intercepted the real toBlob → PNG 3840×3093 px (351 KB) from a 704×567 pane (aspect 1.2416 preserved); rendered the captured blob full-screen and screenshotted it: point cloud + anchor SPHERES only (spheres stay by scene3d design — "friend tags belong in photos"), zero grid/axes/frusta/path-lines/label-sprites.
|
||||||
|
- [x] M14 restore: pixelRatio 1→1, size 704×567, camera.aspect 1.2416, helpersVisible true all restored; shot MID-PLAY → transport paused for the shot and `state.playing === true` after (play-state restored). Works in free-roam; follow-cam uses the same render path (aspect saved/restored around the shot).
|
||||||
|
- [x] M15 pyro fires on PLAY crossing: seek 9.5 → play → burst spawned exactly at t=10.00, opacity 1→0.01 over its 1.0 s life across 53 pumped frames, then removed from the scene (`allRemoved: true`).
|
||||||
|
- [x] M15 confetti fires on SCRUB crossing: paused discrete seeks 16.4→16.6→16.8→16.95→17.1 → burst fired at the 17.1 step (crossing 17.0). Backward jump to 15.0 fired nothing (tracker reset).
|
||||||
|
- [x] M15 bass_drop pulse: play across t=3 → `scene3d.points.scale` swelled to 1.1599 and restored to exactly 1.0 after ~one beat (0.5 s default; tempo from GET /api/beats when it exists).
|
||||||
|
- [x] M15 performance: worst case (all 6 burst slots active + pulse) full frame body (`transport.tick` + `fx.update` + `scene3d.update`) = **0.101 ms/frame CPU** over 300 iterations — ~330× inside the 33 ms/30 fps budget. Pool preallocated once; `update()` allocates nothing; toggle-off removes all objects and restores scale (verified: 0 active, 0 in scene, scale 1).
|
||||||
|
- [x] fx.update can never kill the master loop: whole body in try/catch → on error logs once, disables itself, cleans up (breaker `_dead` verified false throughout).
|
||||||
|
- [x] Zero console errors across the entire live session.
|
||||||
|
- [x] Regression: `uv run pytest backend/tests -p no:warnings` → **127 passed** (floor met; backend untouched). `cd frontend && npm run build` clean (pre-existing >500 kB chunk warning only).
|
||||||
|
|
||||||
|
**Notes / deferred to coordinator (integration2):**
|
||||||
|
- M14 splat path: the DropInViewer is a scene child and renders with the same `renderer.render(scene, camera)` call, so photo mode has no splat branch — but live verification ON A TRAINED SPLAT is deferred (synthetic project has point cloud only).
|
||||||
|
- M15 event→anchor mapping: events carry no anchor id in state, so fx maps event→anchor by the backend's labeling convention (resolved anchor label = `description or event_type`), falling back to the stage centroid (0, 0.5, 0). Both pyro/confetti fired at the centroid in this test (no event-resolved anchors existed); please verify a burst lands ON an anchor after annotating a pyro/confetti event.
|
||||||
|
- M12 interaction: fx pulse writes `points/splat.scale` between fx.update and scene3d.update — same-frame, restored exactly; no interaction with export expected, but a combined FX+export pass is worth one look.
|
||||||
|
- Real-focused-browser eyeball (bursts/pulse at full rAF rate) — the pane verifications above used the pump; a human glance in a focused window is the usual final check.
|
||||||
|
|
||||||
|
**Blockers:** none.
|
||||||
|
|
||||||
|
**Next:** merge `lane/f-social` → `main` (coordinator/integration2 discretion).
