+"""Minimal SARIF 2.1.0 object model for `robotcode analyze code`.
+
+Only the subset of SARIF that we actually emit is modelled. All classes inherit
+from `CamelSnakeMixin`, which turns snake_case fields into the camelCase keys
+SARIF expects (`ruleId`, `physicalLocation`, `startLine`, …). Fields that are
+not valid Python identifiers (`$schema`) use a `field(metadata={"alias": ...})`.
