The 34,048 record removal results agree with the source tables for 266 ds000030 files.
New Python code checks the published baseline and every single GO or STOP record removal for 266 OpenNeuro ds000030 stop-signal task files. All 266 baseline rows, 34,048 removal rows, and 27 summary fields agree with the source tables: discrete values match exactly and time values differ by less than 1e-9 ms. The largest difference is 1/9000000000000 ms. This checks agreement on the same recorded observations; it does not test physical timing precision, task model assumptions, stop-signal reaction time, clinical group effects, or repeat-session reliability. Each file has 32 STOP trials, below the cited consensus guide recommendation of at least 50 for standard group comparisons under favorable conditions.
