+Retention is set to seven days. This is a pickup/recovery window, not a durable evidence store. Trusted-side reconciliation should normally retrieve and delete the artifact sooner after successful pickup/decryption.
 
 The artifact is transport, not durable project authority. Durable conclusions, accepted evidence, negative results, or follow-on decisions belong back in the originating private/project-native authority.
