List AuditRecords

Returns a page of the workspace’s append-only audit ledger in order, filterable by action, principal_id, resource_kind, resource_id, surface_scope_id, agent_definition_id, connection_id, and a since/until window. connection_id answers the per-credential accountability question — who and which agent used one Connection, when, for what — in a single read, including a pre-authorization denial the CapabilityGateway records against the Run. Each AuditRecord carries its actor, outcome, structural detail_json, and the tamper-evident prev_hash and content_hash chain link; the attribution filters are queryable projections outside that hash chain. The contract deliberately has no audit write or delete operation — the ledger is a read surface over exactly what the platform wrote.

Checkfu support posture: alpha; hosted. Required evidence journey: governance-registry. Deployment-specific readiness and the latest proven release are available from GET /v1/support/capabilities.
