CDF crossings and satisfactory mean checks stay after every permitted STOP response removal in 67 ds000030 version 1.0.0 CONTROL runs.
In 243 CONTROL runs from 125 people in ds000030 version 1.0.0, 90 retained a positive GO-minus-STOP mean reaction-time gap after every permitted static STOP-response removal. Of these, 71 had an initial response-conditional empirical CDF crossing. In 67 runs from 60 people, both the positive mean gap and the CDF crossing persisted after every permitted removal. The 67 runs each had a GO response before the earliest STOP response, and exact CDF bounds confirmed a positive STOP-minus-GO CDF difference for every permitted subset. The analysis used 32 STOP trials per run and fixed later task records during removal. It describes finite recorded tables; it estimates no population CDF order, stopping time, model-rejection probability, or biological cause, and it does not show that a race model is incorrect.

[Legacy relation: reproduces] The report supplied the pinned source files, manifest, and mean table. New code agrees on 2,783 comparisons across 253 rows: response counts, selection and mean flags, three means, and the free and permitted mean-failure removal minima. The maximum mean difference is 0.0 ms at a 1e-9 ms tolerance. This relation does not include stopping-time scores or every prior field.
