Cycle integrity and independent verification
Procurement arrives from a partnership announcement describing policy-layer governance. The runtime evidence below documents what is actually executing.
Period integrity
Every record for a monitoring period is included in a Merkle tree per RFC 6962. The tree’s root is signed (Signed Tree Head, Ed25519) and published below. Any party can independently rebuild the tree from records and confirm the root.

Policy describes intent and is reviewed periodically. Runtime emits cryptographic evidence per AI check and is verifiable continuously. The diagram below describes what runs where.
What is documented
Reviewed periodically · executive-signed
- Centralized AI inventory. Every model and use case cataloged in a structured GRC platform.
- Risk-based intake workflows. New capabilities pass a documented assessment before deployment.
- Audit-ready documentation. Policies mapped to NIST AI RMF, EU AI Act, and state laws.
- Periodic model assessments. Performance, bias, and impact reviewed at defined cadence.
What is executing
Continuous · mathematically verifiable
- Ed25519 signature per AI check. Every output paired with a tamper-evident record naming the feature, prompt, evidence-span hash, and time signature.
- Hold on missing evidence. Outputs citing nonexistent spans or unsupported results are blocked before any program reviewer sees them.
- Daily fairness test set. Three text-analysis prompts × five demographic checks. Findings published within 48 hours of detection.
- Per-period Merkle verification. Every record in a monitoring period is included in an RFC 6962 tree. Root is STH-signed and publicly anchored.
