• the candidate rolled in under load with no failed request
• NOT COLLECTED: vulns of reader, catalogue, live, time on side a: grype is not installed (https://github.com/anchore/grype#installation, or set HARNESS_VULN_CMD to another scanner, e.g. trivy)
• NOT COLLECTED: vulns of reader, catalogue, live, time on side b: grype is not installed (https://github.com/anchore/grype#installation, or set HARNESS_VULN_CMD to another scanner, e.g. trivy)

Policy: what b must be informing

Checks on the candidate alone, whatever production is: image hardening (root user, no healthcheck, a secret in the environment or the layer history), build provenance (SLSA provenance from image-build.yml) and the vulnerability ceiling (a critical or high advisory with a fix available). Informing: reported, never gates; a claim can still cover a finding. Hover a cell for what was checked.

Informing (9; 9 unclaimed) reported, never gates

18 of 27 engines are blocking; informing (reported, never gates): timing (no date set to block; load/errors still blocks), image-hardening (no date set to block), build-provenance (no date set to block), vuln-ceiling (no date set to block), timing-tolerance (no date set to block), asset-graph (no date set to block), replay (no date set to block), slo (no date set to block), realtime (no date set to block). An informing engine's findings are listed here and never change the verdict, the Gate or the exit code; a claim can still cover one.

Masks

Fired: response-date×4, request-id×4, etag×4, metrics-process×602, metrics-timing-histograms×4, third-party-requests×62, hashed-assets×222, footer-tutors-version×28, transport-length×4, transport-connection×4, transport-keepalive×4.
Silent this run: persistence-stub-requests, realtime-rest-fallback-warning, oauth-callback-state, media-range-status, chromium-compute-pressure-policy, transport-encoding, transport-transfer — a mask that never fires is a mask to delete.
