With fixed stop outcomes, a common linear time shift changes pooled integration estimates by a mean absolute 62 ms in 134 selected ds002790 v2.0.0 runs

We tested a measurement audit with all 226 stop task event files from AOMIC PIOP2 version 2.0.0. A fixed raw-data rule selected 134 runs. We fit a linear trend to observed go response times. We removed this trend from both response times and stop delays. Stop labels, response availability, choices, and response time relative to the signal stayed fixed. The pooled integration estimate changed by a mean absolute 62.2 ms. Its 95 percent participant bootstrap interval was 51.6 to 73.2 ms. The order reversed for 25.5 percent of person pairs with unequal estimates in both forms. The mean absolute change was 51.4 ms in 79 selected runs with no go omissions. Exact model examples show that a varying common shift can change the estimate with fixed stop latency. The direction depends on the go distribution. The empirical result measures sensitivity. It does not establish a corrected stop latency or a brain effect. The package preserves source files, pinned retrieval URLs and hashes, new audit code, an exact-arithmetic check, results, figures, and a verified offline rebuild. It extends two reports on the same source runs.

We used the preserved source files, pinned manifest, and retrieval recipe. The report of timing changes helped define the audit. We verified all source files with a new download and wrote new analysis code.

We used the raw full-run sample rule and the report of poor half-run agreement to define the question. The new work tests paired estimate changes under a common time shift in the same source people.

usesPairing within task quarters reduced constant latency ranges for pooled stop outcomes in 177 AOMIC PIOP2 runs with fixed empirical margins
Its common-time-shift result showed sensitivity of pooled integration summaries. We used that result to choose a distinct fixed-margin question. We calculated complete constant-latency compatibility ranges rather than another shift test.
