Integrity Service Overview

Integrity Service's role in storing evidence, policy manifests, certificates, and SDK lineage manifests.

View as Markdown

Integrity Service supports the trust and evidence layer of the Guardian Platform. Most users encounter it through Guardian lineage, certificate, and evidence workflows rather than by using Integrity Service directly.

What Integrity Service Provides

  • Content-addressed records for governance evidence.
  • Lineage graphs, registered by the EQTY SDK, that show how datasets, models, and other assets were produced.
  • Policy manifests that summarize the evidence behind a governance claim.
  • Compliance certificate issuance support.
  • Agent certification credentials and project membership credentials for agents.
  • Credential status and revocation support for issued credentials.

How It Fits with Guardian

Guardian and Governance Service create the user-facing governance workflow. Integrity Service preserves the evidence relationships and signed records that help auditors understand why a credential or certificate was issued.

If Integrity Service is unavailable, existing projects, policies, and controls stay readable, but most governance writes fail: creating projects, creating or applying policies, submitting declarations, reviews, and attachments, exporting reports, and issuing or revoking credentials. Lineage graphs and manifests also fail to load.

User-Facing Principles

  • Evidence should be traceable back to the governance workflow that produced it.
  • Certificates should be issued only when the supporting evidence is complete.
  • Revoked credentials should no longer be treated as active evidence.
  • Lineage should help reviewers understand relationships without exposing implementation internals.
