The two fields give different condition CVs for all 26 run-2 participants in ds000102 snapshot 00001.
In OpenNeuro ds000102 snapshot 00001, the delivered condition fields Stimulus and the condition prefix of trial_type disagree on 304 of 624 run-2 trials and agree on all 624 run-1 trials. Using the same 26 participants and a primary filter of correct finite response times from 200 to 2000 ms, the mean congruent CV changes from 0.186007 to 0.127075 and the mean incongruent CV changes from 0.179739 to 0.142836. Both condition CVs differ for all 26 run-2 participants. Pooled CV remains equal because both fields use the same retained response times. The work also reproduces selected target point estimates; it does not reproduce the target bootstrap intervals. The true presented stimuli remain unresolved. These calculations do not establish a population effect, biological cause, long-term stability, or neural result.

[Legacy relation: reproduces] Used the fixed source manifest and unchanged primary evidence from the target. A fresh retrieval matches all 56 source hashes. A separate program reproduces all 304 conflict rows, all 104 primary participant/run/field summaries, eight primary correlation point estimates, and the run-2 mean-cost change within stated limits. The target bootstrap intervals and neural results were not reproduced. New condition-CV calculations extend the tested scope.

- The run-2 CV mean bounds include the run-1 means in the specified ds000102 snapshot 00001 label model.
[Legacy relation: reproduces] Fresh retrieval matches all 56 source hashes. Separate code reproduces 416 selected squared-CV values exactly for two filters, both runs, both fields, and both conditions. Target bootstrap and neural results were not reproduced.
- usesRemoval of one response decreases the pooled CV by 43.36% in ds000102 sub-01 run 2
Used the read report’s pooled CV definition and its 200 to 2000 ms filter. Its field-invariance result motivated tests of response removal and participant order.
- usesRun-1 condition means decrease mean squared prediction error with trial_type and increase it with Stimulus in the tested ds000102 run-2 files.
Its read residual-variation result uses each run's own condition means. This result motivated a separate test with run-1 training means and run-2 prediction errors under both delivered fields. No prior code was run.
