PHASE 1 COMPLETE: mem0 + Supabase integration tested and working
✅ PHASE 1 ACHIEVEMENTS: - Successfully migrated from Qdrant to self-hosted Supabase - Fixed mem0 Supabase integration collection naming issues - Resolved vector dimension mismatches (1536→768 for Ollama) - All containers connected to localai docker network - Comprehensive documentation updates completed ✅ TESTING COMPLETED: - Database storage verification: Data properly stored in PostgreSQL - Vector operations: 768-dimensional embeddings working perfectly - Memory operations: Add, search, retrieve, delete all functional - Multi-user support: User isolation verified - LLM integration: Ollama qwen2.5:7b + nomic-embed-text operational - Search functionality: Semantic search with relevance scores working ✅ INFRASTRUCTURE READY: - Supabase PostgreSQL with pgvector: ✅ OPERATIONAL - Neo4j graph database: ✅ READY (for Phase 2) - Ollama LLM + embeddings: ✅ WORKING - mem0 v0.1.115: ✅ FULLY FUNCTIONAL PHASE 2 READY: Core memory system and API development can begin 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
