🎯 Quality Metrics (Current vs Target)¶

Metric	Current	Target	Status
Subsystems Complete	3/11	11/11	🟡 27%

🚀 Next Actions¶

Immediate (This Week)¶

✅ Complete version_schema documentation
✅ Complete evolution_tracker implementation
✅ Complete compatibility_manager implementation
🏗️ Start migration_engine implementation

Short Term (Next 2 Weeks)¶

Complete compatibility_manager implementation
Create examples for compatibility_manager
Start migration_engine

Medium Term (Next Month)¶

Complete Phase 1 (Foundation)
Begin Phase 2 (Core Systems)
Establish testing framework

📝 Notes¶

Architectural Decisions: - Using C++17 standard throughout - Header-only implementations where possible for performance - RAII patterns for resource management - JSON for serialization (will integrate nlohmann::json) - CMake for build system

Key Dependencies: - 05_20_FABRICATION_TOOLS (generates code to version) - 05_22_COEFFICIENT_CALCULATOR (needs version info) - 05_23_QUALITY_VALIDATION (validates by version) - 05_30_TESTING_FRAMEWORK (cross-version tests)

Risks: - Complexity of dependency resolution (SAT solver) - Performance of sonic fingerprinting at scale - Migration correctness guarantee - Rollback safety in production

🏆 Success Criteria¶

Version Management will be considered complete when: - ✅ All 11 subsystems implemented - ✅ >90% test coverage - ✅ All examples working - ✅ Full documentation - ✅ Integration tests passing - ✅ Performance benchmarks met - ✅ Real-world usage validated

Current Status: Foundation 75% complete (¾ subsystems), 27% overall, ahead of schedule
