Overview

Dual-database connection manager for global and project stores. Lazily opens SQLiteStore connections to the global database (~/.claude/memory.sqlite3) and the project database (.claude/memory.sqlite3 under the project root). Commands query both databases by default, with project facts taking precedence.
