  • <p>This release publishes <strong>NSI Core Spec v1.0</strong>, a compact technical specification that standardizes the <strong>Negentropic Stabilization Index (NSI)</strong> as a cross-domain measure of <strong>stability of structure in time</strong>. The document addresses definition drift across earlier preprints by introducing a <strong>canonical construct</strong> (<strong>NSI:core</strong>) together with a controlled <strong>family of estimators</strong> (<strong>NSI:est.*</strong>), making the NSI program cumulative, reviewable, and reproducible across domains such as <strong>EEG/criticality</strong>, <strong>AI evaluation</strong>, and <strong>operational security governance</strong> (e.g., AKOCS/OTIP-style workflows).</p> <p>The spec provides:</p> <ul> <li> <p>a <strong>canonical target definition</strong> (NSI:core) and strict naming conventions for estimator variants (NSI:est.*);</p> </li> <li> <p>a <strong>multiscale formulation</strong> via a <strong>beta-function</strong> (βNSI) to summarize NSI flow across scales/windows;</p> </li> <li> <p>a <strong>reporting contract</strong> for uncertainty (bootstrap confidence intervals, robustness checks) and recommended negative/positive controls;</p> </li> <li> <p>a one-page <strong>worked example</strong> demonstrating the pipeline: data → windowing → NSI estimator → βNSI → CI;</p> </li> <li> <p>a <strong>cross-domain inventory (“crosswalk”)</strong> that maps each related artifact (papers, datasets, code, pilots) to the NSI construct/estimator used, enabling systematic accumulation of evidence.</p> </li> </ul> <p>This artifact is intended as a <strong>foundation document</strong>: it does not claim new empirical results by itself, but provides the standardized definitions and audit structure required for independent validation studies and operational pilots.</p>
