Evidence Supersession
Direct answer
Evidence supersession preserves the historical receipt, requires an explicit signed transition to a later receipt, and forces dependent assurance claims to be re-evaluated.
Supersession lifecycle
The historical receipt remains addressable and is marked SUPERSEDED.
A later sequence names the prior receipt and carries the current artifact state.
A separate signed supersession record binds prior, successor, reason, authority, and effective time.
Dependent assurance claims are recalculated; they do not silently retain the prior state.
Correction and revocation
Supersession does not erase history. Revocation, correction, staleness, incident response, repair, retest, and currentness transitions remain explicit records with accountable authority and evidence.
