  *
  * Authentication: x-api-key header or Authorization Bearer token required.
  *
  * Query parameters:
- * - account_id (required): UUID of the account whose chats to retrieve
- * - artist_account_id (optional): Filter to chats for a specific artist (UUID)
+ * - account_id (optional): UUID of the target account (validated for access).
+ * - artist_account_id (optional): Accepted for backward compatibility but
+ *   ignored — reserved for the artist-surface migration.
  *
  * @param request - The request object containing query parameters
  * @returns A NextResponse with chats data or an error
