src/routes/(app)/chat/[id]/+layout.ts (3)

24-33: Refactor: Use match function for tab determination.

The use of the match function for determining the tab variable improves clarity and potentially performance. Ensure that the match function is correctly implemented and handles all expected route patterns.

---

55-58: Register revision and handle dependencies.

The code registers the fetched revision and handles dependencies correctly. Ensure that the registerModel function is properly implemented and that dependencies are managed as expected.

Verification successful

---

The getRevision function handles the version parameter appropriately.

The function correctly queries the database based on the presence of a version and includes related data. It handles the case where version is null and ensures that no matching revision results in a null return, which is checked by the calling code.
