Case contract

table = [[item, rarity, weight], ...]. Non-common weights become floor(w*(100+mf)/100) (mf may be negative). With total boosted weight T (None if 0), target = floor(roll*T/10000) for roll 0..9999; return the first item whose cumulative boosted weight exceeds target.

Why this case matters

Game economies leak or destroy currency when one crafting or pricing rule is off by one boundary, rounding stage or state update; the defect is observable in exact integer outcomes.

One recorded failure
