# Implementation Documentation

Phase-by-phase implementation completion records. Each phase that's been built
has a canonical completion note here; original plans and specs are in
[../archive/](../archive/README.md).

## By Phase

### Phase 2.3 — JWT Authentication ✅

### Phase 2.4 — User Management ✅
- (completion notes folded into [../product/STATUS.md](../product/STATUS.md))

### Phase 2.5 — Access Control ✅
- [PHASE-2-5-COMPLETE.md](./PHASE-2-5-COMPLETE.md)

### Phase 2.6 — Security Hardening ✅
- [PHASE_2.6_COMPLETION.md](./PHASE_2.6_COMPLETION.md)

### Phase 2.7 — Health Data Features ✅
- [PHASE27_COMPLETION_REPORT.md](./PHASE27_COMPLETION_REPORT.md) - Completion report
- [MVP_PHASE_2.7_SUMMARY.md](./MVP_PHASE_2.7_SUMMARY.md) - MVP prioritization
- [MEDICATION_MANAGEMENT_IMPLEMENTATION_SUMMARY.md](./MEDICATION_MANAGEMENT_IMPLEMENTATION_SUMMARY.md) - Medication CRUD

## Implementation Progress

| Phase | Status |
|-------|--------|
| 2.3 | ✅ Implemented |
| 2.4 | ✅ Implemented |
| 2.5 | ✅ Implemented |
| 2.6 | ✅ Implemented |
| 2.7 | ✅ Implemented |
| 2.8 | ✅ Implemented (drug interactions) |

## Key Features Implemented

- JWT authentication with token rotation + `token_version` invalidation
- User management (profiles, settings, password change/recovery)
- Permission-based access control + share management
- Security hardening (audit logging, account lockout, session management)
- Medication management (CRUD, dose logging, adherence)
- Health statistics tracking + trends
- Drug interaction checking (OpenFDA-based ingredient mapping)
- Refresh-token persistence (hashed, revocable) + `/refresh` and `/logout`
- Fail-fast production config + real client-IP audit logging
