foundation2 (phase 5a): contracts, stubs, hooks & UI wiring for lanes E/F/G
- DB: paths table (contract #3) + helpers; patch_anchor (label/color)
- API: GET /api/beats, POST /api/director (valid-empty degradation),
/api/paths CRUD (validated POST -> 422), PATCH /api/anchors/{id};
manifest gains capsule:false (test_api.py key-set lock updated consciously)
- CLI: features | direct | capsule subcommands -> lane stubs (exit-2 degradation)
- Backend stubs with frozen contracts in docstrings: audio_features, director, capsule
- Frontend: six lane stub modules imported from main.js; all phase-5 buttons
pre-wired hidden in index.html; write-ui/body.capsule read-only mode;
__F4D_API_BASE__ runtime override in state.js
- Hooks (contract #6): transport.captureAudioStream/releaseAudioStream,
scene3d.focusOn, scene3d.setHelpersVisible (+registerHelper; camPath gizmos)
- Suite 121 -> 127 passed; npm build clean; live-browser verified (status file)
