## Key Findings At A Glance

### Architecture Status: PRODUCTION-READY
- Fully functional multi-tenancy
- Complete auth system with audit logging
- Database perfectly suited for boat documentation
- Security hardening implemented

### Database (13 Tables): EXCELLENT SCHEMA
- `entities`: Boats with full specs (HIN, vessel type, make, model, year)
- `components`: Engines, systems with serial numbers
- `documents`: Organized by type, linked to entities
- Metadata fields: JSON extensibility without schema changes

### API (40+ Endpoints): CORE FEATURES IMPLEMENTED
- Authentication ✅
- Multi-tenancy ✅
- Upload + OCR ✅
- Search ✅
- Permissions ✅

### Integrations: NOT IMPLEMENTED
- Home Assistant webhooks ❌
- MQTT publisher ❌
- Broker CRM sync ❌
- Cloud storage backends ❌
- But architecture supports all of these cleanly

### Gaps for Yacht Sales
| Gap | Impact | Priority |
|-----|--------|----------|
| No MLS/listing integration | Manual document organization | Critical |
| No sale workflow automation | No as-built package generation | Critical |
| No expiration tracking | Can't monitor surveys, certificates | Critical |
| Limited notifications | Missing key user alerts | High |
| No collaboration tools | No buyer sign-off, annotations | High |
| No video support | Document-only system | Medium |
| PWA partial implementation | Design done, code incomplete | Medium |

## Architecture Strengths

1. **Clean Separation** - Routes, services, workers clearly separated
2. **Extensible** - JSON metadata, settings table, queue system ready for extensions
3. **Secure** - JWT, rate limiting, file validation, audit logging
4. **Multi-Tenant** - Organizations, user roles, entity hierarchies
5. **Search-First** - Meilisearch with tenant tokens, page-level indexing

---

## Next Steps After Reading

## Questions This Analysis Answers

**"Is the database schema suitable for boats?"**
→ YES. Entities table has hull_id, vessel_type, make, model, year. Perfect fit.

**"Can we manage multiple boats per broker?"**
→ YES. Organizations → Entities hierarchy supports this.

**"What authentication features exist?"**
→ JWT, refresh tokens, password reset, email verification, audit logging.

**"Can documents expire/be monitored?"**
→ PARTIALLY. Schema supports it via metadata, need to implement notifications.

**"How do we integrate with Home Assistant?"**
→ Create /api/webhooks route, use event-bus service. 1-2 days work.

**"What's the timeline to add integrations?"**
→ 4-6 weeks for MVP with basic integrations, 8-10 weeks for full feature set.

**"Do we need to restructure the code?"**
→ NO. Architecture is designed for clean integration additions.
