Phase 24.2 provides a functional database layer. Phase 24.3 adds production-grade features for enterprise deployment. + +**Q: Can we implement only some features?** +A: Yes. Minimum viable: CMake + Session/MFA + Tests + Backup/Recovery. Defer metrics and replication if needed. + +**Q: What if we don't need multi-instance support?** +A: You can skip State Sync and Replication. Focus on Session/MFA, Backup/Recovery, Tests, and Metrics. + +**Q: How does this integrate with existing Phase 24.2 code?** +A: Phase 24.3 extends Phase 24.2. All existing code remains unchanged. New features add tables and classes but don't modify existing ones. + +**Q: What about Phase 24.4?** +A: Not yet planned. Potential features: advanced analytics, ML anomaly detection, multi-region replication, GraphQL API. + +## Conclusion + +Phase 24.3 planning is complete and comprehensive. All technical specifications, implementation tasks, and success criteria are documented. The team can now proceed with confidence, following the roadmap day-by-day to deliver a production-ready, enterprise-grade database layer for RootStream. + +**Status**: ✅ Planning Complete +**Approval**: Pending +**Implementation Start**: TBD + +--- + +**Prepared By**: GitHub Copilot +**Date**: 2024-02-14 +**Version**: 1.0 + +**Related Documents**: +- PHASE24.2_IMPLEMENTATION_SUMMARY.md (Phase 24.2 recap) +- PHASE24.3_PLANNING.md (Detailed specifications) +- PHASE24.3_ROADMAP.md (Implementation guide) +- PHASE24.3_QUICK_REFERENCE.md (Quick lookup)
