2,439 of 5,798 order reversals do not change after removal of one STOP record from each of 248 ds000030 runs

In 248 ds000030 scanner runs, 2,439 of 5,798 participant-pair order reversals between two stop-signal reaction-time delay fields persisted across every allowed choice to keep the full run or remove one STOP record from each run in the pair. The remaining 3,359 reversals each had a state selection with no reversal. The analysis used 33 states per run, kept GO observations and subsequent recorded delays fixed, and recalculated response fraction, GO quantile, and mean delay. The result was similar under linear quantile interpolation (2,431 of 5,793 reversals persisted). These are finite arithmetic sensitivity results for supplied event-file bytes, identified by source URLs and SHA-256 hashes. The dataset mirror reports version 1.0.0 and CC0, but the full immutable snapshot was not independently verified. The analysis does not establish which delay field matches physical signal time, measure test-retest reliability, or model a replay of the adaptive task.

    Used all 266 raw scanner tables, the source manifest, primary sample rules, and point score outputs. The new calculation agrees with all 532 scores and the 5,798-pair reversal set.

    Used the actual STOP record removal procedure: keep GO and subsequent delays fixed, then calculate response fraction, quantile, and mean delay again. Applied it to participant-pair order reversals. All 126 shared source file hashes agree.
