Self-reported evidence
Submitter-provided evidence may support bounded claims, but independence is limited and the record must say so.
EVIDENCE
Provenance is only as strong as the evidence behind it.
PV keeps evidence source, scope, independence, correspondence, custody, and integrity visible instead of turning heterogeneous evidence into an unexplained trust score.
Governed recordsFail-closed authorityLifecycle continuity
Four controlled evidence tiers.
Corroborated evidence
Multiple sources or stronger correspondence can improve confidence without erasing source limitations.
Independent evidence
Independent or qualified sources support stronger scoped reliance when policy conditions are satisfied.
Highest controlled evidence tier
The strongest evidence tier still remains subject to authority gates, lifecycle controls, and explicit limitations.
Source independence is one dimension, not a magic label.
PV distinguishes submitter-provided evidence from independent or qualified sources, then evaluates whether each object actually corresponds to the requested claim. Later evidence can create a materiality change without rewriting historical state.
PUBLIC TRUST
Trust remains inspectable.
Governed records expose their evidence scope, trust state, lifecycle state, limitations, and authority boundary without upgrading record state into authority that is not live.
