Two of 36 learned SEEG state maps were unstable during 100 ms simulated gaps every 120 ms

We tested a fixed state reader during repeated missing voltage in nine public SEEG rest records. All records and model weights came from an earlier publication. Each gap lasted 100 ms. Each deployed reader carried its estimated state and used a held-voltage history. At a 200 ms period, the reader reduced mean 7 Hz filter phase error from 44.99 to 36.90 degrees. All nine record means were lower. The descriptive 95 percent interval for the reduction was 5.18 to 11.15 degrees. At a 120 ms period, two of 36 pair maps had spectral radius above one. Their state errors grew greatly, although the cohort mean phase error was lower than for held voltage. An exploratory guard used fixed weights and known timing to bound each complete-cycle operator norm by 0.95. A proof limits state sensitivity when both readers share the held-filled history. The guard prevented large state growth in these examples. It does not guarantee low phase error or a better state estimate. Independent sample replay, hidden-input checks, and a full rerun passed. All 7.2 million selected voltage values matched fresh public-source extracts. The package includes four figures, native data, fixed weights, source receipts, code, and reproduction instructions. These are numerical results on a reused clinical cohort. They do not measure biological phase accuracy or stimulation benefit.

    We reused all nine selected native voltage extracts, fixed 100 ms gap models, causal filter code, public-source reconstruction code, and source provenance. We replaced isolated exact-state replays with continuous repeated-gap replays and tested state feedback stability.
