Next-card sensitivity
Each row fixes the next card, then enumerates every remaining river. Values explain board changes; they are not betting advice.

How to interpret the result
An out should be judged by the final showdown it produces, not by whether it improves the hero in isolation.
A heart usually completes the nut flush, while an ace can make top pair. Running queens can also create a winning route that a one-card outs list misses.
The opponent can improve to two pair or trips, so pairing the hero is not always the end of the calculation.
Calculation boundary
This study fixes both known hands. It does not infer ranges, fold equity, bet sizes, position, or future action. The program removes known cards from a standard 52-card deck, enumerates every legal community-card runout, and compares final five-card hands with the practice-table evaluator. Build tests recalculate the source data.
