ZEB8: A Persistence-Based Statistical Alert Protocol for Detecting Coherent Structure in High-Entropy Astrophysical Data

ZEB8 is a persistence-based statistical alert protocol designed to identify non-random, spatially coherent structure embedded within high-entropy datasets. The protocol operates by aggressively destroying structure through multiple null-model controls while preserving global statistics, then measuring whether any residual organization survives this destruction beyond statistical expectation.At its core, ZEB8 distinguishes between two operational states:Universal Host — a null hypothesis ensemble generated via shuffled, phase-randomized, or Gaussianized controls that preserve mean, variance, and power spectrum while eliminating internal coherence.Biological Event — any structure in the decoded data that survives these controls and exhibits statistically significant persistence across spatial scales.The protocol applies a scale-constrained persistence filter that suppresses short-lived, high-frequency fluctuations without injecting artificial structure or altering global amplitudes. Validation is performed through entropy reduction metrics, variance preservation checks, and guarded z-score comparisons against multiple independent null models.ZEB8 includes explicit safeguards against false positives, including:Phase-randomized controls to reject frequency-only artifacts,Degenerate-control detection to prevent inflated z-scores from near-zero variance,Spike and point-source calibration tests to identify non-astrophysical interference.An alert is triggered only when the decoded structure exceeds predefined thresholds (e.g., z₍phase₎ > 5.0) while remaining below artifact-dominated regimes.Although initially developed and validated using simulated cosmological data, ZEB8 is domain-agnostic and extensible to:Cosmic Microwave Background (CMB) analysis,Large-scale structure maps,Geophysical and oceanographic fields,General image and time-series persistence detection problems.The protocol is designed for external replication, with fixed parameters, reproducible seeds, and clearly defined breakdown points. ZEB8 does not assert physical causation; it provides a statistically rigorous method for detecting persistence-optimized structure where standard analyses assume randomness.
