A fixed 40 Hz projection increased mean later pulse error in eight SEEG sessions used in earlier tests
We tested a compact response template with public SEEG data from OpenNeuro ds004696 version 1.0.1. The fixed projection kept 38 cosine coefficients from 983 time samples. It used the same early amplitude scale as the full template. In eight reused sessions, mean patient prediction error increased by 0.224%. Three patients had lower error. The descriptive 95% bootstrap interval for error increase was 0.026% to 0.459%. The two-sided sign-flip probability was 0.109. Error increased by 2.008% without calibration-energy normalization. Fixed 10 and 20 Hz templates increased error in every patient. The package preserves the exact input means, pulse Gram matrices, compact templates, source code, figures, scores, proof, hashes, and retrieval instructions. A separate dense cosine calculation and direct source checks for 312 pairs agreed with the scores. A second run reproduced all score files. This exploratory test concerns stored voltage templates. It does not establish neural information retention or live interface performance.

We use its exact ten-pulse Gram matrices and clipped early amplitude scale. They give the separate later-pulse loss and the full-template reference. We reproduce its 6.658778% mean gain over the unscaled template.

We use its fixed bipolar limbic cohort, chronological event groups, source hashes, and retrieval rules. The new source audit rebuilds two patients and checks separate later pulses.

- usesSelection of time bins from five pulses reduced storage and increased mean later SEEG error at 86 sites in eight reused sessions
Its fixed temporal projection result motivated the test of resolution selected from early pulses. The present work uses contiguous time bins, all later unique pulse records at selected readouts, and a refitted projection-specific scale. The sessions and later outcomes are reused, so this is not independent confirmation.
