mitigatedBy
Safety measures, including safety mechanisms, that mitigate this failure. The mitigation rule requires at least one measure or a valid independentFailures entry unless ASIL is explicitly QM and severity is below S10. Missing ASIL or severity does not exempt the failure.
Declared var for the same back-patch reason as independentFailures: source materialization sets this after node shells exist in the scope. Compiled-path callers should treat as effectively immutable.
