Specular Bit Architecture for Epigenetic Stability. A Formal Basis for Local Susceptibility, Repair Work, and Cloning-Fidelity Studies

Epigenetic maintenance raises a question that sequence fidelity alone cannot answer: can local configuration predict future instability beyond elapsed time, cell divisions, and aggregate alteration burden? This manuscript develops and evaluates a restricted biological interface for the updated Specular Bit Architecture (SBA). Its mathematical ingredients are the exact separation of visible and neutral counter components, conservative State-11 event recording, schedule-independent neutral relaxation work, interaction costs, and finite cascades in a prepared background. These ingredients define candidate descriptors rather than biological laws. A retrospective development comparison used nine forecast records from five fibroblast donors and 113,170 region-record predictions under donor-grouped model selection. Adding the frozen SBA descriptors reduced equal-donor mean squared error from $8.952065\times10^{-4}$ to $8.946924\times10^{-4}$, a relative reduction of 0.0574%; three of five donors and two of three geometry sensitivities favored the augmentation. The result is therefore classified as mixed. No practical effect margin was met or confirmatory inference performed, and no SBA efficacy claim is supported. The protected confirmatory dataset remained unopened, while a subsequent audit found no currently eligible nonprotected replication dataset among eight registered resources.
