B.3:4.8 - Preserve time, currentness, and design/run distinctions
State the exact window only when time changes the assurance conclusion. Monitoring, drift, incidents, evidence refresh, version change, policy change, gate change, or a newly discovered defeater can narrow, reopen, or withdraw a result while the target fact and target-claim identity remain unchanged.
Design evidence and run evidence may support different claims. Produce separate results when target use, conditions, scope, or evidence window differs; compare them instead of merging them into one score.
