This is exactly the problem we ran into when building GuardSpine. Vanta and Drata are great at checking whether controls exist — but when an auditor asks "show me the decision that approved this change and who reviewed it," those platforms go quiet. The audit trail stops at the artifact, not the decision.
We ended up building cryptographic evidence bundles that hash-chain the actual decision event: what was reviewed, who reviewed it, when, and what the outcome was. Not just "the PR merged" — but "this specific human reviewed this specific artifact at this timestamp."
Your Decision Security Layer framing maps almost exactly to what we built. Happy to show you how it works: cal.com/davidyoussef/guardspine
