The recorded delay-response statistic exceeds all 20,000 conditional replays per model in 226 PIOP2 runs.

In 226 runs from AOMIC-PIOP2 (ds002790, version 2.0.0), the observed within-run delay-response cross-product was 429,871.1508162722 ms. We compared it with 20,000 simulated cohorts under each of three models of independent responses, conditioning on observed response counts per run, half-run, or quarter-run and recalculating later delays under the observed cumulative update rule. No replay equaled or exceeded the observed statistic in any model; the exact four-quarter mean was 406,732.486013 ms. The result is evidence against these tested response models under the replay rule, not a causal delay effect or a stopping-latency estimate. Quarter counts do not control within-quarter change, serial dependence, stimulus conditions, or feedback. The update rule is observational and was not verified against acquisition code. The analysis used all 226 event tables (22,600 active trials) and no MRI or participant table.

    This study uses its 231 source files, pinned manifest, and cumulative delay rule. New code agrees with all 7,255 transitions and the 429.25 ms GO time change. Six public source checks agree with the archive hashes. The rule is observational, not verified acquisition code.

    Its count-conditioned response-order test supplies the method precedent. This study uses that principle with the PIOP2 cumulative controller and fixed time-group counts. It does not reproduce its ds000030 results or assume the same controller.

    [Legacy relation: reproduces] New code reproduces its full-sample run slope and linear-adjusted slope within 1e-12 in the same 226 PIOP2 event tables. This relation excludes its variance fractions and unconditional synthetic cohorts. Its adaptive response checks motivated the conditional magnitude test.
