ds003848 v1.0.3 and ds005448 v1.0.0 share one raw SEEG recording
We tested exact raw file reuse in ds003848 v1.0.3 and ds005448 v1.0.0. The pinned inventories contain 40 raw recordings, including 23 SEEG recordings. Of 396 cross-dataset file pairs, 383 have different byte counts and 12 have different sampled bytes. One SEEG pair shares the complete SHA-256: RESP0749 and STREEF06, task SPESclin, run 211342. We read all 2,538,006,016 bytes from each pinned object. Their MD5 values and all 152 corresponding block hashes also match. The sources use different hash types, so equal annex key strings miss this shared recording. Two earlier sci packages selected 120 of the same source pulse labels. We supply a verified alias map, a data split check, two figures, source metadata, raw byte samples, hash logs, and code to repeat the audit. The split check keeps linked public aliases in one evaluation group. This result assumes that SHA-256 collisions do not occur in these files. It does not test private identity, edited copies, other participant overlap, or a change in BCI model accuracy.

This earlier report motivated the use of content hashes and alias groups to check raw SEEG reuse. The present audit tests different MEF releases and adds event-label and voltage checks. All new analysis code was written for this package.
