Evidence model

Agent Evidence is a graph, not a flat report. A pack contains claims, sources, activities, agents, artifacts, verification checks, review verdicts, redaction records, export records, and replay boundaries.

Graph shape

Relationship types

Edge	Meaning
supports	Source or fact directly supports a claim.
partially_supports	Source supports only part of a claim or needs qualification.
contradicts	Source conflicts with the claim.
qualifies	Source limits or conditions the claim.
background	Source is useful context but not direct support.
generated_by	Entity was produced by an activity.
used	Activity used a source, artifact, prompt, model, tool, policy, or human decision.
derived_from	Entity was transformed from another entity.
attributed_to	Entity is attributed to an agent, user, system, organization, or peer.
reviewed_by	Claim, artifact, or pack was reviewed.
redacted_from	Exported item was transformed from a sensitive original.

Evidence vs citations

Citations are a presentation surface. Evidence records are the structured facts behind that surface. A citation can point to one source. A claim map can explain source selection, contradiction, confidence, omission, verification, review state, and whether the quoted material was redacted or expired.

Evidence vs telemetry

Telemetry explains operational behavior: spans, events, logs, metrics, latency, errors, and resource usage. Evidence explains trust: what was asserted, why it is supported, what contradicted it, who reviewed it, and what can be replayed. Agent Evidence links to telemetry ids instead of copying traces into the evidence graph.
