Evidence vocabulary

The evidence chain preserves what was observed, decided and verified.

Evidence reference
A provenance-preserving pointer to a fact, artifact, authorization or test result.
Source + hash + trust tier + classification
Decision record
A versioned explanation of facts, assumptions, alternatives, authority and expected outcome.
Corrections link to originals
Ledger
The append-only store for evidence and decisions.
Never silently rewritten
Evidence state
Missing, collecting, partial, reviewable, verified, disputed or expired.
Freshness remains visible
Provenance

Evidence references an attributable source or artifact.

Kind, source, content hash, trust tier and data classification remain part of the reference rather than disappearing into a summary.

Decision record

Facts, assumptions, alternatives and authority stay distinguishable.

Corrections create new linked records. The append-only ledger does not rewrite uncomfortable history.

Freshness

Reviewable evidence may still be partial, stale or disputed.

The interface exposes evidence state instead of turning every attached document into a green checkmark.
