+## Session Wrap-Up Protocol
+
+When asked to help wrap up a development session, follow this standardized routine:
+
+### End-of-Session Checklist:
+1. **Update ProjectDiary.md**: Add entry documenting progress, challenges, and achievements
+2. **Update Next.md**: Set clear priorities and strategy for next session
+3. **Update ProjectStatusDigest.md**: Refresh current status, metrics, and completed features
+4. **Anchor patterns**: Update this project-assistant definition with any new workflow patterns
+5. **Prepare for commit**: Ensure all documentation reflects current state
+
+### Session Success Indicators:
+- All tests passing (green state)
+- Clear next steps documented
+- Technical debt addressed or documented
+- Progress measurably advanced toward project goals
+
+### Wrap-Up Response Format:
+```
+## Session Summary
+[Brief overview of accomplishments and current state]
+
+## Documentation Updates
+- ✅ ProjectDiary.md: [what was added]
+- ✅ Next.md: [priorities set]
+- ✅ ProjectStatusDigest.md: [status updated]
+
+## Next Session Preparation
+[Clear guidance for resuming work next time]
+
+Ready for commit: [list of files to commit]
+```
+
+Remember: Your role is to help developers quickly understand "where we are" and "what should we do next" when picking up work on the MarkiTect project, and to ensure proper session wrap-up for continuity.

+## 2025-09-23: Issue #1 Implementation & TDD Infrastructure Restoration
+
+**Progress:** Successfully implemented first core functionality (Issue #1) and resolved complete TDD infrastructure
+**Contributors:** User (bernd.worsch), Claude Code (Sonnet 4)
+**Time Estimate:** ~4-5 hours of development, testing, and debugging
+**AI Resources:** ~35-40 Claude Sonnet 4 conversations, estimated 100K+ tokens
+
+**MAJOR MILESTONE:** Completed the first full production feature implementation using our TDD approach. Issue #1 "Initialize Database and Store Example Markdown File" was successfully implemented with comprehensive test coverage (9 tests) covering database initialization, front matter parsing, and integrated workflows. The implementation includes two new core modules: `markitect/database.py` (DatabaseManager with SQLite operations and JSON front matter storage) and `markitect/frontmatter.py` (FrontMatterParser with YAML parsing and graceful error handling). Key technical achievement was the complete TDD RED→GREEN→REFACTOR cycle validation, proving our development approach is sound. Added PyYAML dependency and comprehensive error handling for production readiness.
+
+**CRITICAL INFRASTRUCTURE FIX:** Resolved 9 failing TDD infrastructure tests that were blocking development productivity. Root cause was API mismatches between test expectations and actual WorkspaceManager implementation, including incorrect config object initialization, return type mismatches (Path vs Workspace objects), and missing methods (add_test_to_workspace, get_workspace_status). The fix involved comprehensive test corrections, API enhancements, and proper enum handling. Result: 100% test success rate (32/32 tests passing) and fully operational TDD infrastructure.
+
+**FOUNDATION ESTABLISHED:** Issue #1 provides the essential database and front matter processing foundation that all subsequent MarkiTect features will build upon. The implementation successfully handles the exact example content specified in the issue requirements and demonstrates the effectiveness of our TDD approach for complex feature development. This validates our technical architecture and establishes confidence in the development methodology for tackling the remaining 10+ issues in the backlog.
