Independent Verification

Prove every AI decision.

This is a real EVE decision record. Click Verify and confirm — yourself, offline, against EVE's published key — that it is authentic and unaltered. Then click Tamper & re-verify and watch the proof break. No EVE account. No live connection to EVE required.

ECDSA P-384 signed SHA-256 content integrity Independently replayable

Load a real, EVE-signed CoreGuard decision that carries the external policy that governed it — then verify its signature yourself against EVE’s published key.

Checking signing posture…
What you’ll see: the decision (ALLOW / MODIFY / BLOCK), the policy it was enforced under, and the external governance provenance — which external system & policy governed it. Then the certificate is verified live.
✓ Verification DOES prove
The signed contents are unchanged since EVE issued the certificate. The decision and policy shown are authentic and were not altered after signing.
● Verification does NOT prove
That every underlying source fact was true, or that the policy itself was legally correct. Signature verification establishes integrity and authorship — not real-world truth.
How it works: Click Load a sample record to get a real, freshly-signed EVE governance certificate. Click Verify to check its ECDSA P-384 signature and SHA-256 content hash against EVE’s published keys. Then click Tamper & re-verify to modify one field and watch the proof fail.

No account required. No connection to EVE servers needed. Every certificate is verifiable offline using the published key at /.well-known/eve-pubkey.
Verification Use Cases
Regulatory Audits

Provide auditors with independently-verifiable governance proofs for AI decisions made in lending, insurance, or regulated industries. No API call needed — auditors verify offline.

Model Risk Review

Validate that every AI decision was enforced through the deterministic policy gate. Confirm policy version and decision route for model validation frameworks.

Legal Discovery

Produce signed, tamper-evident records of AI decisions for litigation or regulatory inquiry. Full chain of custody and audit trail.

Third-Party Integration

Verify that external AI agents met your governance requirements. Confirm capability limits, decision routes, and policy compliance without sharing source code.

Show raw verification fields

You just verified one of ours. The question that matters is what happens to one of yours.

Send us a single de-identified decision — one row, no customer names — and we’ll run it through CoreGuard and return the signed certificate, free, usually within a day. When you’re ready to see the whole population rather than one record, the 60-day Charter Design Partner pilot back-tests your historical decision logs in shadow mode, touching nothing in production.
