**Footnote.** Received = files as downloaded (Temple: raw EDF files, identical copies counted once; shard datasets: files listed at conversion; older datasets: files in our training format, raw counts not tracked). Usable = converted and passed QC. Hours = unique EEG time from file headers; no overlapping windows, no augmentation. Subjects are summed over datasets and not de-duplicated (some cohorts overlap, e.g. DS004504 / DS004504_PHOTIC and the Iowa PD sets). PARKINSON_TLV also exists as shards and is counted once, in B. Assessments = comparisons on the 45-assessment accuracy slide: the rows sum to 43, plus 1 pooled age assessment (CAUEEG + DS004504 + PARKINSON_UCSD) and 1 sleep-staging assessment on the external Sleep-EDF cohort, which is not in the corpus. v11 = a research retrain with ten extra datasets, not the production encoder; screening runs = short (3,000-step) Temple pretraining experiments.
