# execute_webhook_message_deletion

Permanently delete one exact privately credentialed Discord webhook message after a fresh matching content-bearing plan, signed interactive approval, durable webhook and message exclusion, a unique one-shot operation-key reservation, pending content-free activity, one non-retried mutation, and exact absence readback while confirming that the webhook credential remains valid. Credentials, credential paths, execution URLs, review reasons, and message content never enter durable records.
