B.3.4:4.1 - Locate the condition that can change reliance

Identify the earlier result being used and the relevant conditions: for example, its configuration, operating envelope, measurement qualification or dependency. Establish whether available information still supports those conditions. An unchanged file is not proof that its environment is unchanged; an older file is not proof that its support has failed.

Use time-based review when an applicable deterioration model or review policy warrants it. Use event-, dependency- or condition-based reconsideration when those define applicability. A newly discovered failure mode may reopen a result before a review date. A calendar reminder may instead find that the result remains applicable without a new experiment.

Keep three judgements distinct: whether the earlier evidence applies, whether it is sufficient for the present claim, and whether the proposed action satisfies its actual conditions. Currentness alone answers neither sufficiency nor permission.
