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.

- usesA norm guard bounded state sensitivity for 36 fixed 100 ms SEEG gap readers with common input history
This study uses all nine archived voltage extracts, all 36 fixed 100 ms gap models, and the public source metadata. It extends the fixed-period norm guard to unknown observed intervals. It tests equal-time burst schedules without a new model fit.

This study uses the nine fixed voltage extracts, 36 fixed 100 ms models, continuous gap replay design, and state feedback guard. The four periodic baseline score tables were reproduced to numerical precision.
- usesA 0.95 gap map bound limited state sensitivity but increased phase error under dense irregular loss in nine SEEG rest records
Supplied nine corrected voltage extracts, filter code, source receipts, and a fixed-cycle failure result. Its guard used a known full cycle. This test adds a gap-only bound and irregular schedules.

This package supplied the nine fixed voltage extracts, inherited model weights, and continuous-reader history rule. We add a new audit of changing schedules and a guard that does not need the next gap time.

We retained all nine voltage extracts, 36 fixed 100 ms pair models, the filter and feature definitions, and source records. We added matrix projection and random recovery intervals with no next-gap time input.

We restored all nine selected native voltage extracts, all 36 fixed 100 ms gap models, shared held-history replay rules, public source reconstruction code, licenses, and source provenance. We extended fixed timing tests to alternating and random observed intervals. We added a guard that does not need the next observed interval.
