DOCA.1.CHR:4.8 - Reopen the smallest affected scope
Reopen when the subject or configuration, receiving use, horizon, scenario, characteristic meaning, scale, polarity, measurement method, evidence window, protected condition, or decision-relevant unknown changes. Trace that change to the smallest affected opportunity, comparison, or advice claim.
Do not discard unaffected readings merely because one characteristic changed. Do not retain a composite maturity score when its underlying meaning or weighting changed.
