Measures contributor-sentiment signals on <upstream> over a configurable window: thread tone (first-response classification), time-to-first-reply (median hours), first-PR retention (second-PR rate), and reviewer load (Gini coefficient). Compares each signal against a pre-adoption baseline and produces a structured gate report used to decide whether a skill family is ready to advance from experimen
