+
+**Tables** (All present, properly indexed):
+```sql
+notes (9 columns)
+  - id, slug, file_path, published, created_at, updated_at,
+    content_hash, deleted_at, html

+
+### Identified Gaps (Expected for Phase 5)
+
+1. **No RSS Feed** (Primary Phase 5 deliverable)
+   - Module: `starpunk/feed.py` - NOT YET CREATED
+   - Route: `/feed.xml` - NOT YET IMPLEMENTED
+   - Tests: `test_feed.py` - NOT YET CREATED
+
+2. **No Production Container** (Secondary Phase 5 deliverable)
+   - Containerfile - NOT YET CREATED
+   - compose.yaml - NOT YET CREATED
+   - Health check - NOT YET IMPLEMENTED
+
+3. **No Feed Discovery Links** (Phase 5 template update)
+   - base.html needs `<link rel="alternate">`
+   - index.html needs RSS nav link
+
+4. **No Container Configuration** (Phase 5 infrastructure)
+   - Reverse proxy configs - NOT YET CREATED
+   - Container orchestration - NOT YET CREATED
+
+**Analysis**: All gaps are expected Phase 5 deliverables. No unexpected issues.

+**Migrations**: None needed for Phase 5
+**Data**: Test data structure supports feed generation
+
+### Architecture: ✅ READY
+
+**Routes Blueprint**: Easy to add /feed.xml route
+**Module Structure**: Clear location for starpunk/feed.py
+**Configuration**: Config system ready for feed settings
+**Templates**: Base template ready for RSS discovery link
+
+## Phase 5 Implementation Prerequisites
+
+### ✅ All Prerequisites Met
+
+1. **Phase 4 Complete**: Web interface fully functional
+2. **Authentication Working**: Both production and dev auth
+3. **Notes Module Stable**: CRUD operations tested
+4. **Templates Functional**: Microformats markup correct
+5. **Testing Infrastructure**: Ready for new tests
+6. **Documentation Standards**: ADR template established
+7. **Versioning Strategy**: Clear versioning path to 0.6.0
+8. **Dependencies Available**: feedgen ready to use
+
+### Architectural Decisions Locked In
+
+These decisions from previous phases support Phase 5:
+
+**ADR-001**: Flask framework - supports RSS route easily
+**ADR-002**: Minimal Flask extensions - feedgen is appropriate
+**ADR-003**: Server-side rendering - feed generation fits
+**ADR-004**: File-based storage - notes easily accessible
+**ADR-007**: Slug generation - perfect for feed GUIDs
+**ADR-008**: Semantic versioning - 0.6.0 is correct bump
+**ADR-009**: Git branching - trunk-based development continues
+
+## Recommendations for Phase 5
+
+### 1. Implementation Order
+
+**Recommended Sequence**:
+1. RSS feed module first (core functionality)
+2. Feed route with caching
+3. Template updates (discovery links)
+4. RSS tests (unit + route)
+5. Validation with W3C validator
+6. Container implementation
+7. Health check endpoint
+8. Container testing
+9. Production deployment testing
+10. Documentation updates
+
+**Rationale**: RSS is primary deliverable, container enables testing
+
+### 2. Testing Strategy
+
+**RSS Testing**:
+- Unit test feed generation with mock notes
+- Route test with actual database
+- Validate XML structure
+- Test caching behavior
+- W3C Feed Validator (manual)
+- Multiple RSS readers (manual)
+
+**Container Testing**:
+- Build test (Podman + Docker)
+- Startup test
+- Health check test
+- Data persistence test
+- Compose orchestration test
+- Production deployment test (with HTTPS)
+
+### 3. Quality Gates
+
+Phase 5 should not be considered complete unless:
+- [ ] RSS feed validates with W3C validator
+- [ ] Feed appears correctly in at least 2 RSS readers
+- [ ] Container builds successfully with both Podman and Docker
+- [ ] Health check endpoint returns 200
+- [ ] Data persists across container restarts
+- [ ] IndieAuth tested with public HTTPS URL
+- [ ] All tests pass (target: >405/410 tests)
+- [ ] Test coverage remains >85%
+- [ ] CHANGELOG updated
+- [ ] Version incremented to 0.6.0
+- [ ] Implementation report created
+
+### 4. Risk Mitigation
+
+**Risk**: RSS feed produces invalid XML
+- **Mitigation**: Use feedgen library (tested, reliable)
+- **Validation**: W3C validator before commit
+
+**Risk**: Container fails to build
+- **Mitigation**: Multi-stage build tested locally first
+- **Fallback**: Can still deploy without container
+
+**Risk**: IndieAuth fails with HTTPS
+- **Mitigation**: Clear documentation, example configs
+- **Testing**: Test with real public URL before release
+
+**Risk**: Feed caching causes stale content
+- **Mitigation**: 5-minute cache is reasonable
+- **Control**: Configurable via FEED_CACHE_SECONDS
+
+## Phase 5 Design Validation
+
+### Design Documents Review
+
+**phase-5-rss-and-container.md**: ✅ COMPREHENSIVE
+- Clear scope definition
+- Detailed specifications
+- Implementation guidance
+- Testing strategy
+- Risk assessment
+
+**ADR-014-rss-feed-implementation.md**: ✅ COMPLETE
+- Technology choices justified
+- Alternatives considered
+- Consequences documented
+- Standards referenced
+
+**phase-5-quick-reference.md**: ✅ PRACTICAL
+- Implementation checklist
+- Code examples
+- Testing commands
+- Common issues documented
+
+### Design Alignment
+
+**Architecture Principles**: ✅ ALIGNED
+- Minimal code (feedgen, no manual XML)
+- Standards first (RSS 2.0, RFC-822)
+- No lock-in (RSS is universal)
+- Progressive enhancement (no JS required)
+- Single responsibility (feed.py does one thing)
+
+**V1 Requirements**: ✅ SATISFIED
+- RSS feed generation ✓
+- API-first architecture ✓
+- Self-hostable deployment ✓ (via container)
+
+## Code Review Findings
