From 380ed16b67984b337e1451c33fcc43519409e585 Mon Sep 17 00:00:00 2001 From: Claude Date: Fri, 23 Oct 2026 20:00:54 +0000 Subject: [PATCH] Fix CycloneDX row links and NaN coverage ratios Each CycloneDX row now uses its own advisory, source, or reference URL instead of the previous row's. Coverage kinds with no records print N/A in list, and validate skips that threshold with a warning.

The severity comes from the SARIF property `security-severity` when a result or its rule has one. The value is a number from 0 to 10, or a numeric string. 9.0 and above is critical, 7.0 to 8.9 is high, 4.0 to 6.9 is medium, above 0 and below 4.0 is low, and 0 is none. A result property wins over the same property on the rule. When neither is set, gatecheck uses the SARIF level. A missing result level uses the rule's `defaultConfiguration.level`, then `warning`. `error` is high, `warning` is medium, `note` is low, and `none` is ignored. - `ruleLimit` and `ruleRiskAcceptance` each have `enabled` and `rules`.
