# Lane F — Social & fun UX (branch `lane/f-social`)

**Scope: phase-5 milestones M13 + M14 + M15** (anchor manager + friend tags, photo mode, moment FX) — see [`20-phase5.md`](20-phase5.md).

- Owned files: `frontend/src/anchorPanel.js`, `frontend/src/photoMode.js`, `frontend/src/fx.js`.
  Nothing else — buttons, imports, and hooks are pre-wired by foundation2.
- Contracts you consume (frozen): `PATCH /api/anchors/{id}` + existing anchor GET/POST/DELETE,
  `scene3d.focusOn(x,y,z)`, `scene3d.setHelpersVisible(bool)`, `scene3d.addObject/removeObject`,
  the M8 annotation flow (drive it, don't modify `annotate.js`).
- This is the "friends connect & remember" lane — labels, colors, and jump-to should feel like
  tagging people, not editing database rows. Keep interactions one-click where possible.
- All verification is in-browser: use the `__f4d` debug pump (phase-5 pitfall #2) and put
  screenshots/measurements in your status file. No backend tests to write; the suite must
  simply stay green.

**Done when:** M13–M15 acceptance passes with browser evidence, frontend `npm run build` clean,
merged to `main` with synthetic end-to-end intact.
