Public source tables restore 5,474 EEG choice codes in ds004917 v1.0.1

In OpenNeuro ds004917 v1.0.1, 23 EEG event tables stored reaction time instead of choice for 5,474 of 5,665 decision events. Matching all 24 distinct public OSF behavior tables to each EEG recording by stimulus values, reaction time, and ordered trial sequence yielded one unique match for every recording. All 191 valid original choices agreed with their matched source. An independent check confirmed the repairs and unchanged event fields. The event dictionary probability equation failed on all 3,595 ambiguity trials and agreed on all 3,590 clear trials. A clipped visible-mass relation fit all 7,185 decisions within a maximum residual of 0.000004, but does not establish how the stimulus program generated a mask. A specified fMRI benchmark changed substantially when it used the documented equation instead of stored probability. The results concern event data and that benchmark; they do not test brain signals or establish an error in the original neural analysis. Matching assumes the public source rows describe the same task decisions, and the work was exploratory without preregistration or a held-out dataset.
