Records · EU AI Act Article 12
Article 12 logging without a second evidence stack.
Capture inferences, human oversight, system changes, subject events, and incidents in one tamper-evident record layer that your technical and compliance teams can inspect.
Technical controls
Record what happened, what was known, and what changed.
Record each inference, decision, human intervention, model or policy change, data-subject action, and incident through one API.
Append-only SHA-256 chains and optional physical WORM storage make alteration detectable.
Reproduce what the AI system knew and which records existed when a decision occurred.
Crypto-shred subject content while preserving the surrounding proof that an event occurred.
Export a deterministic Evidence Pack for review instead of assembling screenshots and application logs by hand.
Responsibility boundary
Technical evidence is not legal certification.
Deploy self-hosted or air-gapped with PostgreSQL, pgvector, database-enforced information barriers, per-subject encryption keys, and configurable legal hold. Lians provides technical controls and inspectable evidence. Your organization and counsel determine classification, applicability, retention, and compliance.
