How the verdict is decided
The verdict comes from the gap between the two HearWiki scores: 10+ points is a clear upgrade, 5-9 meaningful, 2-4 marginal, within a point a sidegrade, and anything negative a downgrade. Sub-score bars and the spec table are computed from the catalog, and the written verdict is assembled from those same numbers by fixed rules - there's no model guessing at request time, so the same pair always reads the same way.
