Energy Filament Theory (EFT) A14: Full-Spectrum Separation Protocol Family — CMB/SZ/Foreground μ/y/r Templates, Absolute Radiometry, and Residual Whitening

Key Points

The aim is to present a workflow for effectively separating cosmic microwave background (CMB) micro-distortions from other astrophysical signals.
Defined workflows for separating CMB and SZ contributions using absolute radiometry.
Utilized μ/y/r template projection for accurate signal differentiation.
Implemented residual-whitening diagnostics for quality assurance.
Included optional three-window injection-history tomography.
Successfully distinguished CMB spectral distortions from SZ contributions and foreground astrophysical signals.
Improved accuracy in measurements and audits through the defined protocol.

Abstract

This record publishes EFT-A14, the “Full-Spectrum Separation Protocol Family” in the EFT methods-layer protocol library. A14 defines an auditable workflow to separate CMB spectral micro-distortions from SZ contributions, astrophysical foregrounds, and instrumental systematics, using full-spectrum absolute radiometry, μ/y/r template projection (including a transition-window residual template R(ν)), residual-whitening diagnostics, and optional three-window (μ/r/y) injection-history tomography. The module is aligned to the audit clause Z13/T7.
