Comprehensive guide for migrating from JSON to node:sqlite when Node 24 is available:
- Schema design (model_outcomes + model_stats tables)
- Phase-by-phase refactoring approach
- Data migration from JSON with backward compatibility
- Testing strategy with new SQLite-specific tests
- Future opportunities: dashboards, trend analysis, A/B testing, federated learning
This doc serves as a roadmap for ~2 days of work when Node 24 becomes standard.
