[error] 28-28: Don't use '{}' as a type.

Prefer explicitly define the object shape. '{}' means "any non-nullable value".

---

[error] 230-230: Don't use 'Object' as a type.

Prefer explicitly define the object shape. This type means "any non-nullable value", which is slightly better than 'unknown', but it's still a broad type.

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.

---

50-54: Ensure proper handling of the version parameter.

The code correctly handles the version parameter, fetching the specific revision if provided. Ensure that the getRevision function is robust and handles edge cases, such as invalid versions.

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.
