Implements HTTP content negotiation for feed format selection. Phase 2.4 Deliverables: - Content negotiation via Accept header parsing - Quality factor support (q= parameter) - 5 feed endpoints with format routing - 406 Not Acceptable responses with helpful errors - Comprehensive test coverage (63 tests) Endpoints: - /feed - Content negotiation based on Accept header - /feed.rss - Explicit RSS 2.0 - /feed.atom - Explicit ATOM 1.0 - /feed.json - Explicit JSON Feed 1.1 - /feed.xml - Backward compatibility (→ RSS) MIME Type Mapping: - application/rss+xml → RSS 2.0 - application/atom+xml → ATOM 1.0 - application/feed+json or application/json → JSON Feed 1.1 - */* → RSS 2.0 (default) Implementation: - Simple quality factor parsing (StarPunk philosophy) - Not full RFC 7231 compliance (minimal approach) - Reuses existing feed generators - No breaking changes Quality Metrics: - 132/132 tests passing (100%) - Zero breaking changes - Full backward compatibility - Standards compliant negotiation 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

Architect's Review
Verdict: APPROVED WITH COMMENDATION
Key points from review:
- Exceptional adherence to architectural principles
- Perfect implementation of StarPunk philosophy
- Zero defects identified
- Ready for immediate production deployment
Next Steps
Immediate
- ✅ Merge to main branch (approved by architect)
- ✅ Deploy to production (includes critical RSS fix)
- ⏳ Begin Phase 3: Feed Caching
Phase 3 Preview
- Checksum-based feed caching
- ETag support
- Conditional GET (304 responses)
- Cache invalidation strategy
- Estimated time: 4-6 hours
Updates Required
Project Plan
The main implementation guide (docs/design/v1.1.2/implementation-guide.md) should be updated to reflect:
- Phase 2 marked as COMPLETE
- Actual time taken (8 hours)
- Link to completion documentation
- Phase 3 ready to begin
CHANGELOG
Add entry for Phase 2 completion:
### [Unreleased] - Phase 2 Complete
