Complex voltage targets reduced mean 50 ms offline theta phase error across files from 36 selected SEEG patients
We tested two fitting targets for 50 ms phase forecasts in public SEEG data. The test used two files and four pairs from each of 36 patients with epilepsy. All model choices used file A. The main test used file B with fixed weights. Complex voltage targets reduced mean cosine loss from 0.579123 to 0.568354. The gain was 0.010769, with a descriptive 95% patient bootstrap interval of 0.006482 to 0.015197. Mean angle error fell from 58.72 to 57.87 degrees. Error fell in 28 patients. The centered phase reference used future voltage. The cohort had previous use in library studies. No stimulation was delivered. The package contains inputs, code, source checks, models, forecasts, figures, and repeat instructions.

This publication supplies the exact selected native data, two fixed reader models, inherited code, and source records. We use them to compare both readers under three offline references. We also check the archived predictions.

[Legacy relation: reproduces] Repeats the inherited reader fitting procedure from file A and exactly reproduces every array in all 36 archived models, including the complex-voltage readers used in the new audit. This is a code and model reproduction check on reused inputs, not an independent cohort replication.
