What is AI enforcement infrastructure?

AI enforcement infrastructure is the layer that intercepts and enforces policy on AI actions before they execute, ensuring agents cannot take unauthorized actions even when instructed to do so.

What is fail-closed execution in AI systems?

Fail-closed execution means that if an AI agent cannot verify it has authorization to take an action, it refuses to proceed. No action is taken without a valid, verified approval.

How does AI Syndicate differ from logging tools?

Logging tools record what happened after the fact. AI Syndicate enforces policy before execution occurs and records who approved what, with what parameters, under which policy version.

Audit & Evidence Generation

This page defines the audit record, hash chaining, and trace linkage required to satisfy INV-5.

INV-5

Spec Drift Warning

Changes to implementation that violate invariant mappings invalidate compliance with v1.0. Implementations MUST preserve invariant-to-component, invariant-to-artifact, and invariant-to-verification-step mapping.

Compliance Assertion

• Satisfies INV-5 by requiring attributable records for approvals, denials, and execution outcomes.

Non-Compliance Results In

• Missing denial records are non-compliant.
• Broken hash chaining or missing trace linkage invalidates compliance evidence.

Audit Record Contract

Invariant Mapping: INV-5

Every request MUST produce an attributable audit record, including denials.

• Each audit record MUST contain record_id, timestamp, identity, decision, request_hash, trace_id, and data_hash.
• Execution records MUST include approval_id and execution outcome.
• Denial records MUST include a denial decision code.

Hash Chaining & Trace Linkage

Invariant Mapping: INV-5

• Audit records MUST be linked by previous_hash or equivalent tamper-evident ordering field.
• All records for a request MUST share the same trace_id.
• All records for a request MUST share the same request_hash.

Required Evidence Exports

Invariant Mapping: INV-5

• Implementations MUST support export of request, approval envelope, execution trace, and audit chain.
• Exports MUST preserve field values used during verification.
• Exports MUST be sufficient to confirm denials as well as approvals.

Compliance Evidence

• Sample audit chain export with hash continuity.
• Sample denial record proving denied requests are logged.
• Verification output confirming trace_id and request_hash linkage.

Verification Linkage

INV-5

Artifact: audit-chain-001.json

Check: Hash continuity and trace linkage validate

Verification step: verify.sh: INV-5

INV-5

Artifact: audit-chain-001.json

Check: Request hash and approval_id correlate with execution trace
