Deterministic Verification for CI Security Decisions (Introducing Nono-Gate)

Modern CI/CD pipelines run multiple security scanners. They detect vulnerabilities, produce reports, and sometimes block builds. However, the final security decision — the decision that allows a release to proceed — is usually derived from tool outputs and pipeline logic that are difficult to verify later. In most environments, the decision is effectively trusted rather than independently verifiable. Nono-Gate explores a different architectural approach. Instead of treating scan results as the final artifact, Nono-Gate treats the security decision itself as a verifiable artifact. The system introduces a deterministic verification layer for CI security decisions. It consumes security signals (for example SARIF outputs from scanners), applies a deterministic policy evaluation process, and produces a structured decision artifact backed by verifiable evidence. This allows the decision to be replayed and verified later, even outside the original CI environment. Core capabilities Determinist
