Prior to version 0.19.5, GET /api/books/{bookID}/notes is an unauthenticated endpoint that accepts a \"deleted\" query parameter. When the request is ?deleted=true, the service runs the query with Unscoped() (bypassing GORM's soft-delete scope) but keeps the read-authorization clause as \"owner_id = ? OR is_public = ?\". As a result, any unauthenticated caller can enumerate the metadata of soft-deleted (\"trashed\") notes belonging to any public book — notes the owner explicitly deleted and expected to be removed from public view.
