The scoring is reproducible as tiers but not as values: on a blind re-score of a stratified 18-problem sample by a different model, the filter kill decision agreed 100%, identification of which advance is the target agreed 83%, lane assignment 72%, individual dimensions agreed exactly only 28-67% of the time (83-94% within one point), and the summary reachability scale differed by a mean of 1.67 points.
