On 30 August 2026, the wireless prototype completed a worn acquisition run automatically after 300.047 seconds. It preserved 74,856 EEG samples per channel across 9,357 EEG packets, together with 5,612 movement-sensor samples. The measured EEG sampling rate was 250.0 Hz across four finite channels.
The completed run reported zero missing, duplicate, out-of-order, or malformed EEG packets, zero timestamp anomalies, and zero queue drops. The board was battery-powered and connected wirelessly, without a conductive USB path to the wearer.
The session included blinks, jaw movements, and head movements. Responses were visible in the corresponding intervals. Those responses help characterize what reaches the recorder; they do not establish clean neural signal or deliberate attention decoding. Raw recordings remain private.
Earlier interrupted attempts are retained as separate evidence. An accidental device power-off ended one attempt, and an operator-requested restart exposed a cleanup defect that was repaired. The completed run does not erase those failures or prove uninterrupted operation in other conditions.
This milestone verifies acquisition for this run. It is not a stationary calibration baseline, a command-accuracy result, or a validated live demonstration. Previous directional probes did not generalize on held-out trials. Reliable separation of left, right, and idle remains unproven in the current montage.
