# TASK-004-010: Update ARCHITECTURE.md test coverage status

Update documentation to reflect HTTP/3 test parity achieved in Feature 004.

## Changes

1. **Implementation Status table**: Updated HTTP/3 score from 82/100 to 88/100 to reflect integration and security test coverage now at parity with HTTP/2.

2. **Testing Structure section**: Enhanced documentation to explicitly show:
   - 16 integration test files in H3/ (matching H2 categories: smoke, connection, concurrency, cache, cookie, compression, request compression, redirect, retry, error handling, edge case, feature interaction, handler pipeline, resilience, expect-continue, max stream concurrency)
   - 4 security/fuzz test files in Http3/Security/ (QPACK bombs, frame fuzzing, field validation, security attacks)

3. **Feature file**: Marked TASK-004-010 acceptance criteria complete.

All acceptance criteria met:
- ✅ ARCHITECTURE.md "Implementation Status" HTTP/3 score updated to reflect test parity
- ✅ "Open gaps" section verified (no test-related items—feature gaps remain as appropriate)
- ✅ Testing Structure table reflects H3 integration test coverage
