No governance claim without a witness.
A witness is an auditable reference that makes a claim, decision, object, evidence item, authority or time boundary reviewable.
In SnapOS, a witness is not a rhetorical citation. It is the minimal audit reference that allows a claim to be checked, reopened and bounded.
Source Witness
Where did the claim or object come from?
Object Witness
Which document, workflow, model or artefact was actually audited?
Evidence Witness
Which evidence supports which claim, and where does it stop?
Temporal Witness
At what date, version and snapshot is the finding valid?
Authority Witness
Who can approve, review, challenge, override or decide?
Reviewer Witness
Who produced or reviewed the output, and under what status?
These six witnesses form the public core set for general governance evidence. The full SnapOS Conformance Schema also includes Decision Witness and Transfer Witness where decision reliance or context transfer is involved.
Governance without witnesses becomes narrative. SnapOS converts governance claims into bounded, reviewable and reopenable audit objects.
