Exact permutation probabilities are more than 0.31 for all 102 distribution crossings in 122 selected ds000030 controls.
In 122 selected controls from OpenNeuro ds000030 version 1.0.0, GO and failed-STOP reaction-time distributions crossed in 102 controls (83.6066%). Exact fixed-count permutation reference probabilities were all greater than 0.31 (minimum 0.31559758024437834). These descriptive results do not establish biological independence or race-model validity. The analysis pools STOP delays, does not model serial dependence or task history, and uses the same observations for selection and comparison; the permutation probabilities do not account for selection.

Used its v1.0.0 control input files, pinned source manifest, and subject metric table. Verified all 441 archive files, fresh source bytes for the 129 selected inputs, and 1,008 count, selection, and mean entries. No prior code was executed. The new CDF calculation does not refute its stated model-validity limitation.

- Rounding to 10 ms decreases CDF crossings from 205 to 190 in 241 selected ds000030 files.
[Legacy relation: reproduces] The new code gives the same CDF values and integer permutation counts for all 126 controls. It does not repeat the prior extra response-rule tests.
- usesPooled and delay-cell rejection rates varied across four simulated stop-signal models
Its exact one-sided pooled CDF rank reference supplied the statistic definition and continuous equal-law label assumptions. New integer-count code tests that reference with adaptive simulated responses.
- usesA 1,000 ms limit changes conditional response distributions in 36 of 122 tested ds000030 control runs.
The exact CDF statistic, initial 102-of-122 count, and sub-10527 correct-GO warning enabled baseline checks and a stated post-result sensitivity check. Its permutation probabilities were not used.
- usesThe rank checks do not give a task error limit for each planned delay in 121 selected ds000030 control runs.
Used its fixed-count rank reference and its stated task limits to select the delay-specific error-limit question.
