- Around line 135-140: Update the schema-version handling around onDiskVersion
and CURRENT_SCHEMA_VERSION to explicitly handle on-disk versions greater than
the current version: refuse loading with an unsupported-schema error, or back up
the raw data before migration can down-stamp it. Ensure newer-version files are
never silently migrated and persisted with unknown top-level keys discarded.
In `@src/main/services/connectors.service.ts`:
- Line 137: Update the connections retrieval flow around getField('connections')
to deep-clone each connection, including its nested connection object, before
returning or passing the collection to extractSchemaFromConnection and
executeQueryForConnection. Preserve the existing empty-array fallback, and add a
regression test covering credential materialization followed by an unrelated
database update without persisting credentials.

replacement behavior.

store - Handle database.json written by a newer app build (e.g. after a downgrade): back up the file and pass its contents through without running them through the reconstructive migration whitelist, which was silently dropping any field this older build didn't recognize. - Make DatabaseStore.getField/getSnapshot return a deep clone instead of a live reference into the in-memory cache. Callers that enrich a returned connection with a secure-storage credential for immediate use (e.g. ConnectorsService.extractSchemaFromConnection) were mutating the cache itself, so the next unrelated write could persist plaintext credentials to database.json. - Add a structuredClone polyfill to the Jest jsdom test environment (jsdom 20 here predates native support, added in v21).

Keep uniqueness validation independent from reserved-name validation.
allowReservedNames currently disables the complete duplicate-name check. It also does not reject "DBT Connection" on ordinary save paths. A duplicate name can share name-based credential keys with another connection.
Always check uniqueness. Separately reject the reserved name when allowReservedNames is false.
Proposed fix
