EVE AI Core
The Infrastructure of No.
EVE Trust Services Controlled Preview
EVE Trust Services preserves, witnesses, and verifies governance evidence across models, agents, providers, and time. Now available in controlled preview for selected design partners — hosted verification, cryptographic custody manifests, and externally witnessable evidence infrastructure. Evidence custody and managed witnessing remain subject to production-readiness and contractual approval.
Product architecture
Every governed AI decision moves through three product layers before an external party verifies it. Each layer has one job.
Input
AI action proposed
A model, agent, or workflow proposes an action that carries risk.
Enforce
EVE CoreGuard evaluates
Deterministic pre-execution enforcement returns ALLOWED, BLOCKED, or MODIFIED.
Prove
EVE Proof signs
The decision becomes a signed certificate — verifiable offline, bound to the policy version.
Preserve
EVE Trust Services witnesses and preserves
Evidence is externally witnessed, held in custody, and kept verifiable over time.
Verify
Auditor or examiner verifies
An external party checks signatures, inclusion proofs, and replay — without trusting the producer.
CoreGuard governs. EVE Proof proves. EVE Trust Services preserves independent trust.
Capabilities
Eight services that keep governance evidence verifiable long after the system that produced it has changed.
Witnessing
External witnessing
Signed Merkle roots submitted to an independent append-only transparency log, so evidence existence is attested outside the producer's control.
Custody
Evidence custody
Long-term preservation of customer-owned evidence chains with strict tenant isolation. Your evidence remains yours — held, not owned.
Proofs
Inclusion proofs
Cryptographic proof that a governance record was included in a previously witnessed evidence root — checkable by any verifier.
Keys
Key lifecycle continuity
Rotation, revocation, and continuity records that preserve trust in old signatures across infrastructure and key changes.
Replay
Deterministic replay services
Reproduce historical governance decisions using the original policy version and evidence context — the same inputs, the same verdict.
Verification
Verifier APIs
Auditors, regulators, customers, and approved third parties validate evidence without any access to signing authority.
Migration
Attested migration
Evidentiary continuity when customers migrate infrastructure, keys, regions, or governance environments — with a signed record of the transition.
Retention
Long-term retention
Regulated retention periods, deletion proofs, and evidence-chain continuity for the full life of the record-keeping obligation.
Assurance vocabulary
A published vocabulary for how much independent verification stands behind a piece of AI decision evidence.
Why it matters
A model provider can report what its platform says happened. Independent evidence infrastructure allows another party to verify what happened without relying solely on the model provider.
Evidence handling is separated from the systems that produce decisions, so no single vendor's account of events has to be taken on faith.
One evidence format and one verification path across every model and agent in your estate — regardless of who built or hosts them.
Evidence chains stay verifiable when workloads move between clouds, regions, or deployment models.
Auditors verify signatures and inclusion proofs directly, without requiring access to production systems or vendor cooperation.
Evidence arrives in a form an examiner can independently check: signed, witnessed, replayable, bound to the policy version in force.
Verification does not depend solely on vendor-controlled logs that the vendor could alter, truncate, or lose.
Trust EVE less. Verify the evidence more.
Where it fits
EVE Trust Services is designed for organizations whose AI decisions are subject to supervision, examination, or formal audit.
Supports model risk management practice with preserved, independently verifiable records of how governed model decisions were enforced and evidenced over time.
Helps operationalize the Govern and Measure functions with durable evidence of enforcement outcomes, policy versions, and verification history.
Provides artifacts for record-keeping and post-market monitoring processes: witnessed evidence roots, inclusion proofs, and replayable decision records.
Provides artifacts for control operation and evidence-retention activities within an existing SOC 2 control environment.
EVE Trust Services supplies evidence infrastructure and verification artifacts. It does not certify compliance, and framework alignment does not constitute a compliance guarantee or a legal opinion.
Ownership & privacy
Independent trust infrastructure only works if the customer keeps ownership and the witness sees no secrets.
Customers retain ownership of their evidence and decision data at all times. Custody is a service, not a transfer of rights.
Each tenant's evidence chains are held in strict isolation. No cross-tenant access, aggregation, or correlation.
EVE Trust Services does not require public disclosure of prompts, outputs, policies, or customer records to deliver external witnessing.
External transparency logs receive cryptographic roots and required verification metadata — never raw decision content.
Any aggregated benchmark use of evidence requires explicit customer consent and anonymization. No silent reuse.
When retention ends, deletion is executed against the customer's policy and evidenced — without breaking the continuity of the surrounding chain.
Verification workflow
Six steps from a single decision record to an independently checkable conclusion.
Retrieve the decision certificate
The verifier obtains the signed decision certificate from the customer's evidence store or export.
Resolve to a witnessed evidence root
The certificate resolves to an evidence root previously witnessed in the independent transparency log.
Check signature validity
The verifier checks the certificate's signature against the published verification key material — no signing authority required.
Validate the inclusion proof
The verifier validates the cryptographic proof that this record was included in the witnessed root.
Replay the decision
The original policy version and decision context can be replayed to confirm the recorded verdict is reproducible.
Independent evaluator issues any opinion
Any formal opinion on the evidence is issued by an independent evaluator — not by EVE.
Division of responsibility: EVE supplies the evidence infrastructure — certificates, witnessing, proofs, replay. Independent auditors and validators issue formal opinions.
Status
EVE Trust Services builds on evidence infrastructure that already ships with EVE CoreGuard and EVE Proof. Status is stated plainly.
Design partners shape the witnessing, custody, and verifier surface before general availability. They generate decisions. EVE preserves the proof.
