Four evidence types

Observed

Farna Control retrieved or directly recorded the fact: a run started, a connector returned a response, a gate received a decision, or a file was produced.

Derived

Farna Control calculated or evaluated the result from observed evidence, such as an evaluation score, a policy outcome, a hash-chain check, or a cost total.

Reported

An agent, CI system, scanner, or connector supplied the claim. Farna Control retains that provenance instead of presenting the claim as something it independently observed.

Attested

A human or a Farna Control governance action formally recorded a decision, such as approving a human-in-the-loop gate or accepting a release outcome.

A concise evidence artifact

A run record might retain a small, inspectable envelope like this:

{
  "run_id": "run_01J...",
  "fact": "release artifact checksum matched manifest",
  "source": "Farna Control installer verification",
  "kind": "derived",
  "based_on": ["observed: artifact download", "observed: signed manifest"],
  "recorded_at": "2026-11-08T12:00:00Z"
}

The artifact says what was checked and how the result was classified. A reported agent claim can remain useful evidence without being relabelled as an observation.

What Farna Control does not claim

Farna Control does not claim proof of private agent reasoning, universal software safety, absence of vulnerabilities, or complete observation of every external action. Evidence narrows uncertainty around recorded work; it does not turn a bounded record into a guarantee about everything outside it.

That distinction is why each artifact keeps its source and type visible. Readers can decide what the record supports, what remains a reported claim, and what still needs human judgement.

Community and Team

Single-run verification is free in Community. You can inspect the evidence for an individual run without paying for an organization-scale feature.

Team adds org-scale verification and export: review evidence across an organization, verify the audit chain, and export records for offline or compliance workflows.
