This record publishes Appendix A4 of the public edition of Energy Filament Theory (EFT): a four-dimensional evidence-reading operating system that decomposes any observational or experimental dataset into four aligned panels (Image, Polarization, Time, Spectrum) and requires same-window cross-checks before interpretations are elevated to conclusions. A4 embeds three EFT-critical protocol patches—Sx (Chromaticity/Blurring Check), Ix (Anti-lensing/Divergence Fingerprint), and Tx (Noise–Force Phasing)—and enforces explicit Null Semantics (Null result vs Not checked) for auditable reporting.
