- Implement 7 core unified API methods (add, search, import, addNoun, addVerb, update, delete) - Add universal encryption system with encryptData/decryptData methods - Add container deployment support with model preloading - Implement soft delete by default for better performance - Add searchVerbs() and getNounWithVerbs() for graph traversal - Reduce package size by 16% despite major feature additions - Create comprehensive CHANGELOG.md and MIGRATION.md - Consolidate CLI from 40+ to 9 clean commands - All scaling optimizations preserved and enhanced BREAKING CHANGES: - addSmart() method removed (use add() - smart by default) - CLI commands consolidated and renamed - Pipeline classes unified into single Cortex class This is the complete 1.0 release candidate with all planned features implemented and tested.
