No dedicated repository. This case documents policy-gate patterns; supply-chain decisions that policy can enforce live in BlastGuard.
Case 15 · Pattern
Policy as Code Guardrails
A CI turnstile that teaches: versioned policy packs evaluate before promote and return readable remediation — standards without tribal gatekeeping.

How it works
Pass the turnstile — or learn why.
Policy as Code Guardrails by Andrey Lesnikov — OPA-style packs in CI that block bad promotes and teach the fix.
-
01
Write policy as code
Rules live in versioned packs — reviewed like any other platform contract.
-
02
Evaluate in CI
The turnstile spins on every PR and image — early, automatic, consistent.
-
03
Deny with a lesson
Failures return remediation humans can act on — not a silent red X.
-
04
Allow and promote
Passing the gate continues delivery without waiting for a tribal approver to wake up.
02
Evidence
From problem to proof.
How the system is framed, operated, and proven — not a slide deck summary.
01
CI and admission still disagree: promote decisions rely on tribal review instead of machine-readable policy.
02
You need zero-trust service identity/mTLS fabric rather than delivery gates — see Zero Trust Service Mesh.
03
BlastGuard issues supply-chain decisions that policy can enforce. Secrets and Certificate Automation keeps identity material lifecycle-managed.
Constraints
Developer experience, admission control, exception handling, auditability, and avoiding fragile gatekeeping.
