Integrity Service helps create the durable records behind policy manifests and compliance certificates.

## Policy Manifests

A policy manifest summarizes the policy context and supporting governance evidence for a claim. It helps users and auditors understand what evidence was considered when a certificate or governance record was produced.

## Certificates

Compliance certificates represent issued governance claims. Integrity Service supports certificate issuance and credential status workflows, while the Guardian Platform presents the user-facing credential views.

## Revocation

When a credential is revoked, users should no longer rely on it as active evidence. Revocation can happen when governance work is archived, a decision changes, or the certificate should no longer be trusted.

## Review Guidance

- Confirm project, policy, and subject information before issuing a certificate.
- Review related declarations, reviews, and indicators, and the lineage of any model or dataset they rely on.
- Keep certificate issuance aligned with the organization's approval process.
- Revoke credentials when they should no longer be accepted.
