Score up to 64 labelled time intervals and 128 command events: rest false activations, missed trials, wrong commands and first-correct response times. Public or synthetic event metadata only. No raw EEG, participant identifiers, live control, diagnosis or human-enhancement claim.

Verdict: not verified by an unpaid GET. 200: serves without a payment challenge. This says nothing about whether the route works when called as declared.
