+The parallel /simplify sweep's schema.rs agent wrapped create_tables() in a transaction for atomicity. This broke all 5 integration tests because in-memory SQLite with max_connections>1 gives each connection its own database — the transaction committed on one connection, but test queries ran on another that had no tables. Discovered and fixed by limiting in-memory pools to max_connections=1.
