Delete ratelimit override

Permanently remove a rate limit override. Affected identifiers immediately revert to the namespace default.

Use this to remove temporary overrides, reset identifiers to standard limits, or clean up outdated rules.

Important: Deletion is immediate and permanent. The override cannot be recovered and must be recreated if needed again.

Permissions: Requires ratelimit.*.delete_override or ratelimit.<namespace_id>.delete_override
