How grades on this page work

Each image is scored 0–100 by the cerodeo-v2 Rodeo rubric. Grade bands: A ≥ 85 B ≥ 70 C ≥ 55 D ≥ 40 F < 40.

An image starts at 100 and loses points for open CVEs: −25 per fixable Critical, −10 fixable High, −3 fixable Medium, −8 unfixable Critical, −3 unfixable High. It earns points back for hygiene: non-root default (+10), rebuilt in last 90 days (+10), cosign signature (+5), SLSA provenance (+5), SHA256 pinned (+5), SBOM attestation (+3), HEALTHCHECK (+3), OCI labels (+3), multi-arch (+2–3), upstream GH release (+3), README example (+2).

A-grade means score ≥ 85. Working backward from the formula: an image earns A when it has zero fixable Critical CVEs (one is a −25 hit, drops you out of A no matter the hygiene) and at most one fixable High CVE (−10 brings you to 90, still A). Fixable Mediums at −3 and unfixable Highs at −3 are cheap; you can carry a handful before dropping to B. Hygiene bonuses buffer against the smaller CVE penalties — non-root default (+10) alone covers two unfixable Criticals. A publisher with many A grades is one that consistently hits that math: not just avoiding CVEs by accident, but shipping with signed provenance, non-root defaults, and timely rebuilds. The AVG SCORE above is the average 0–100 Rodeo score across the 0 scanned images in this namespace.

Full rubric with every weight at /about/grades. Changes to any weight ship as a new rubric_version so old snapshots stay auditable.
