 ## Project Overview
 
-Web-based SQL IDE for cloud-native teams: 17 engines — the `DatabaseType` union in [`src/lib/types.ts`](src/lib/types.ts) is the list, never a prose enumeration — plus AI query assistance.

+Web-based SQL IDE for cloud-native teams: sixteen external engines, plus the embedded LibreDB store — `EXTERNAL_DATABASE_TYPES` in [`src/lib/db/compatibility.ts`](src/lib/db/compatibility.ts) is the external-engine list, never a prose enumeration — plus AI query assistance.
