## 9. BUILD HEALTH

### TypeScript Configuration
| File | Purpose |
|------|---------|
| `tsconfig.base.json` | Root config with path aliases |
| `apps/api/tsconfig.json` | Backend-specific settings |
| `apps/web/tsconfig.json` | Frontend-specific settings |

**Status:** ✓ Proper monorepo setup with shared base config

### ESLint & Code Quality
- **eslint.config.mjs** (149 lines) — FlatConfig v9 format
- Ignores: node_modules, dist, .next, coverage
- Plugins: TypeScript ESLint, import-x, prettier
- **Status:** ✓ Modern flat config, no issues detected

### Turbo Build System
- `turbo.json` (22 lines) configured:
  - `build` → outputs dist/ + .next/, depends on ^build
  - `dev` → persistent, no caching
  - `lint, test, typecheck` → depend on ^build
- **Status:** ✓ Correct dependency graph for monorepo

### Build Artifacts
- Root `pnpm-lock.yaml` (470 KB) — pinned dependencies
- `.turbo/` cache directory present
- Corepack configured via `.pnpmrc.json`

- valuation — AVM integration UI
- seo — Meta tags, Open Graph, structured data
- comparison — Side-by-side property compare
- providers — API/context providers setup
- ui — Buttons, forms, modals, cards (base design system)

**Status:** ✓ Well-organized, feature-driven architecture

### State Management

| **API Test Coverage** | ✅ Strong | 226 unit/integration specs |
| **Frontend Test Coverage** | ❌ **Critical Gap** | 0 unit tests; vitest setup exists but unused |
| **CI/CD** | ✅ Mature | 7 pipelines, CodeQL, load testing, backups |
| **Docker** | ✅ Complete | Multi-service, dev/CI/prod configs |
| **Documentation** | ✅ Comprehensive | 74 files covering architecture, API, deployment |

## RECOMMENDATIONS

1. **Frontend Testing:** Write 50+ React component tests for critical paths (auth, search, checkout)
2. **API Docs:** Generate OpenAPI/Swagger docs automatically; docs exist but could be auto-indexed
3. **E2E Expansion:** Add 20+ more Playwright tests for payment flows, agent workflows
4. **Monitoring:** Verify Prometheus scrape config + Grafana dashboards are production-ready
5. **Load Testing:** Schedule K6 tests weekly; track performance baselines
6. **Dependency Audit:** Review TypeScript 6.0 stability pre-production deployment
