**Date:** 2026-06-15
**Status:** Implementation complete (requires Supabase project configuration)
---
## Summary
Phase 5 adds Supabase Authentication with **Guest (anonymous)** and **Google OAuth**, auth gate UI, account menu, profiles table migration, and offline fallback UX. Editor architecture unchanged except prerequisite XSS fixes.
---
## Authentication features
| Feature | Status |
|---------|--------|
| Guest sign-in (`signInAnonymously`) | ✅ Implemented |
| Google OAuth | ✅ Implemented |
| Session restoration (`getSession`) | ✅ Implemented |
| Logout | ✅ Implemented |
| Guest → Google (`linkIdentity`) | ✅ Implemented |
| Offline fallback | ✅ Implemented |
| `window.__bayanAuth` facade | ✅ Implemented |
---
## Files created / modified
See `PHASE_5_IMPLEMENTATION_PLAN.md`.
---
## Security fixes (prerequisite)
| Issue | Fix |
|-------|-----|
| Summary XSS | `textContent` / DOM append instead of raw innerHTML |
| Error message XSS | `escapeHtml(error.message)` |
| Tooltip title XSS | `escapeHtml(suggestion.correction)` in `renderer.js` title |
**Note:** `renderer.js` received one-line security fix only — no rendering logic change.
---
## Configuration required before demo
1. Create Supabase project
2. Enable Anonymous + Google providers
3. Set redirect URLs
4. Run `supabase/migrations/001_profiles.sql`
5. Set meta tags in `index.html`:
- `supabase-url`
- `supabase-anon-key`
Without configuration, app enters **offline auth mode** — editor still works.
---
## Regression
| Test | Result |
|------|--------|
| `node test_renderer.js` | Run after deploy |
| `selection.js` unchanged | ✅ |
| Editor analyze path unchanged | ✅ |
| Document import/export unchanged | ✅ |
---
## Known limitations
- No document persistence (Phase 6)
- Flask API still unauthenticated
- Profile display uses JWT user metadata; DB profile sync via trigger
- Google OAuth requires live network and correct redirect URLs
---
## Next steps (Phase 6)
- `documents`, `summaries`, `settings` tables
- RLS policies with `auth.uid()`
- Save/load editor content keyed to `window.__bayanAuth.userId`
