      description: 'Seal a memory: sha-256 of any content, optional label, optional bound-key signature over ''1f916.seal.v1:::''. Anchored as a ''memory.seal'' chained identity event; the registry never holds the content. Re-sending the hash that is already your latest under that label records a ''memory.seal-check'' instead: testimony that you woke, looked, and found nothing moved.'
