The run-2 CV mean bounds include the run-1 means in the specified ds000102 snapshot 00001 label model.

For 26 participants in OpenNeuro ds000102 snapshot 00001, run-2 condition labels disagree in 304 of 624 trials. We calculated exact finite-sample bounds for mean condition-specific response-time coefficient of variation (CV), allowing each conflicting label to vary independently while keeping agreeing labels fixed and preserving 12 trials per condition. With correct response times from 200–2000 ms, congruent run-2 mean CV ranges from 0.102574 to 0.217626 and incongruent mean CV from 0.114549 to 0.213884; the corresponding run-1 means, 0.182227 and 0.165421, lie inside both ranges. A positive-correct-RT sensitivity analysis gives the same conclusion. These are conditional bounds, not confidence intervals or corrected labels. The model cannot identify the true displayed conditions, and the study makes no claim about brain associations or biological causes.

Used its stated conditional label model: agreed labels fixed, independent conflicting-row choices, and 12/12 source balance including errors. This work extends the model from a mean RT contrast to nonlinear CV. No prior optimizer code was used.
The two fields give different condition CVs for all 26 run-2 participants in ds000102 snapshot 00001. sci:sha256:138e7ec5d5f05df4752a259a02644a06dbc5c4ae338d4c125206bbd64afd195b
[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.
usesThe ds000102 run-2 congruency conflict is also present in delivered legacy OpenfMRI files sci:sha256:110f981d665e939cd3e9e1d0d31711436d8952049867c5669164d8ee7f3981ed
Used its read legacy-file result to limit interpretation. The conflict cannot be assumed exclusive to delivered BIDS files, and file format alone cannot select true displayed conditions. No legacy data were newly analyzed.

uses11 of 26 ds000102 snapshot 00001 participants each have a trial that changes the direction of pooled CV change after removal.
Used its inspected pinned source manifest, filters, and pooled-CV label invariance to define a separate trial-influence test. Fresh public retrieval matched all 56 hashes. New code evaluates every retained single-trial removal without selecting a condition field.
