EU AI Act

EU AI Act oriented agent verification evidence

Autonomous agents raise audit expectations under the EU AI Act. AffixIO signed allow or deny outcomes with Merkle references give you verifier-checkable evidence of what was permitted, without claiming a formal certification.

Definition

EU AI Act oriented verification evidence is a pack of signed policy decisions showing which agent actions were allowed or denied at the boundary.

Field note. Policy documents without verify evidence do not satisfy operational AI Act reviews. Attach proof to every agent gate.

Architectural alignment, not certification

AffixIO helps you produce signed boundary decisions. That supports auditability patterns discussed in EU AI Act field notes. It is not a certification that your system is Act-compliant.

Gate consequential agent actions. Retain Merkle refs. Document policy versions. Pair with organisational governance.

Practical evidence set

Agent ID, action class, allow or deny, proof metadata, Merkle reference, policy or circuit version, timestamp. Keep prompts out of the verifier by default.

Read the EU AI Act verification field note and agentic governance whitepaper for narrative structure.

Production wiring for EU AI Act agent evidence

For EU AI Act agent evidence, provision sandbox circuits that mirror production predicates before you expose live agent traffic. Capture sample allow and deny payloads for regression tests.

Keep identity and rich attributes with the issuer. Verifiers receive outcomes and Merkle metadata only. Sync audit refs to your SIEM or order store after the gate returns.

Wallet mismatch

Prompt logs are weak compliance artefacts

Regulators and auditors asking how agent behaviour was controlled will not be satisfied by chat transcripts alone.

No decision objects

Systems log outputs, not signed permissions.

Unclear accountability

Hard to show who or what authorised an action.

Over-claiming risk

Vendors imply certification AffixIO does not assert.

Gate design

EU AI Act evidence packs for agent verification

EU AI Act obligations on high-risk agent systems need verifiable evidence that gates fired, not policy PDFs alone. Merkle-linked verify outcomes give auditors replayable proof of agent controls.

  1. Identify high-risk agent actions

    Under your governance model.

  2. Gate with AffixIO

    Signed allow or deny.

  3. Retain evidence fields

    Standard schema.

  4. Review with counsel

    Legal interpretation stays yours.
