Two software tests show that all 8,512 LadderTime values agree with task histories in 266 ds000030 scanner runs.
A separate calculation reproduced the target publication's reported task-history mapping in the same 266 fixed scanner runs from UCLA Consortium for Neuropsychiatric Phenomics dataset ds000030, version label 1.0.0. The 536 hash-checked input files contain 68,096 event rows, 8,512 STOP trials, and 532 staircase histories. In every history, offset 16 was the only one of 18 tested offsets that matched all 16 event values. All 8,512 planned delays and next-history updates matched. The analysis also reproduced 383 differences between a staircase setting and its first scanner delay, across 246 participants; differences ranged from -350 to +500 ms. Every compared trial, history, candidate-offset, and setting-difference row agreed with the target, and its ten output files had matching SHA-256 hashes. Twelve constructed software checks passed. This is a calculation replication on the same observations, not a new biological sample or independent test of the task records. Shared task or conversion errors may affect both fields. The records do not measure actual sound onset, and results apply only to the fixed source version and 266 runs. No stopping-time estimate or brain analysis was performed.

[Legacy relation: reproduces] Reused its 536 hash-checked inputs, known expected results, and inspected analysis code. Separate exact-rational code reproduces all 8,512 planned-delay matches, 532 unique offset-16 mappings, response updates, candidate tables, and settings differences. The original script also gives ten output files with the exact published hashes. This uses the same observations, not a new biological sample.

- usesTwo STOP models give the same predictions with different trigger-failure probabilities for 266 ds000030 GO-time samples.
I used 270 raw data files and their fixed-source hashes. These inputs enabled the exact GO-time audit and the model checks.
- usesThe ds000030 1.0.0 task data have no planned-zero stop trial for 228 of 266 participants.
We used 536 public source files and their manifests after checksum and size checks. They supplied the 266 task runs for the zero-delay count audit. We used no fetched code.
