## Backend API Coverage

| Category | Routes | Notes |
|----------|--------|-------|
| Legacy overlays | GET `/api/live/friends`, GET `/api/live/clans/:clanId` | Keeps LIVE SOCIAL strip powered |
| Sessions | POST `/sessions`, GET `/sessions/:sessionId`, GET `/sessions`, POST `/sessions/:id/{join,leave,end}` | Authenticated (Fastify + `authMiddleware`) |
| Participants | POST `/position`, POST `/role`, DELETE `/participants/:userId` | Enforces tier/role guards |
| Chat | POST `/chat`, GET `/chat/:sessionId` | Rate-limited (10/min) |
| Safety | POST `/emergency`, DELETE `/emergency/:sessionId` | 5/hour guard |
| Telemetry | POST `/telemetry`, POST `/laps`, GET `/leaderboard/:sessionId` | Track-day metrics |
| Export & Stats | GET `/sessions/:sessionId/{replay,export,stats}` | GPX / CSV / JSON + analytics |

## Documentation Updates

| File | Lines | Change |
|------|-------|--------|
| `LIVE_NAVIGATION_DOCS_INDEX.md` | 46 | Rebuilt as tables with real links + learning paths |
| `LIVE_NAVIGATION_SYSTEM.md` | 1,852 | Verified Fastify/HTTP narrative, full route table, three-system overview |
| `LIVE_NAVIGATION_QUICKREF.md` | 496 | Actual LOC metrics, 21-route table, updated status |
| `LIVE_NAVIGATION_BUGS_FIXED.md` | 30 | New fix log (browser-safe globals, listener symmetry, event bus cleanup) |
| `LIVE_NAVIGATION_COMPLETE.md` | 605 | (This file) condensed metrics + quality status |

Reference: `docs/README.md` requires table-first documentation; every update above follows that style.

## Quality & Testing Status

| Check | Status | Notes / Command |
|-------|--------|-----------------|
| ESLint (MapPage.mobile.vue) | ✅ | `pnpm exec eslint apps/web/src/modules/map/pages/MapPage.mobile.vue` |
| Full lint (apps/web) | ⚪ Pending | Run `pnpm lint --filter web -- --max-warnings=0` |
| Type-check (api + web) | ⚪ Pending | Run `pnpm type-check` across the monorepo |
| Manual review | ✅ | Confirmed no direct `window`/`navigator` usage; `rg` now shows guarded helpers only |
| Runtime safety | ✅ | MapPage now defers browser APIs via `runtimeWindow`/`runtimeNavigator` |

---

## Next Steps

| # | Action | Owner |
|---|--------|-------|
| 1 | Re-run lint + type-check pipelines and capture logs in `LIVE_NAVIGATION_BUGS_FIXED.md` | Engineering |
| 2 | Promote `runtimeWindow/runtimeNavigator` helpers into a shared utility so other mobile pages can reuse them | Frontend |
| 3 | Add component tests (or e2e) covering emergency trigger + chat drawer to prevent regressions | QA |
