Evidence
Evidence that stands on its own. Every action across every system produces verifiable proof — independently verifiable without trusting the service that produced it.
Evidence Constructs
AEA
Versioned operational evidence artifacts. Schema-specific signing, identity/runtime binding, and independent verification — with signer and algorithm per schema version.
AEA details →ATP
Evidence-grounded operational trust profile. Independent dimensions derived from verifiable evidence — not a generic login score or authentication assurance metric.
ATP details →Additional Evidence Types
Trust Objects
Signed evidence bindings issued by the operating environment. Every governed action produces a Trust Object that can be independently verified.
Context Bundles
Complete execution context captured at the time of an action. Identity, policy decisions, and runtime state.
State Commitments
Cryptographic commitments to organizational state at specific points in time. Enables tamper detection across the state history.
Node Evidence
Evidence produced by ACTA Node Fabric nodes. Job claims, execution starts, results, and lifecycle evidence.
Verifier Outputs
Outputs from the independent verifier. Verdicts, evidence checks, and assurance tier assessments.
External Anchoring
Optional external anchoring of evidence digests. When configured by the tenant, provides external verifiability.
Portable Verification
Evidence packages can be exported and verified independently. The verifier does not need to trust the producing service — it validates the evidence against published schemas and cryptographic commitments.
