//! SARIF output tests for the dynamic verification vendor extension (§5.4).
//!
//! Acceptance criterion: SARIF output contains both
//! `partialFingerprints.dynamic_verdict_status` and
//! `properties.nyx_dynamic_verdict` for every `VerifyStatus` variant, and
//! both keys are absent when no dynamic verdict is attached.
