⚑ Evidence disagreements 51

Variants where the independent computational evidence doesn't line up with the clinical picture — a QC signal for a second look, not a reclassification.

Predictors lean, ClinVar uncertain 42

ClinVar classifies these uncertain (VUS), but the independent predictors unanimously lean one way — a triage signal for review, not a reclassification.
