Anti-tail and Extremely Slow Rotation Confirm the Electromagnetic-Null Recombination Mechanism for 3I/ATLAS (C/2025 N1) and the SL9 Prototype – Addendum v1.1

This 2-page addendum (v1.1) to the original papers 10.5281/zenodo.17822276 (Shoemaker-Levy 9 – Magnetic Unzipping) 10.5281/zenodo.17817852 (3I/ATLAS – 511 keV Engine) presents new December 2025 observations: a persistent sunward (cyan) anti-tail and an extremely slow rotation period of 72–120 hours. These two features jointly confirm the directed annihilation beam (equation 3) and fossil magnetic-field locking predicted by the electromagnetic-null recombination mechanism. No standard sublimation/aberration model predicts both simultaneously. The anti-tail is the photographic proof that 3I/ATLAS is being driven by a beamed 511 keV annihilation exhaust. All original predictions remain unchanged and are now visually corroborated. Authors note: Welcome to a new understanding in the universes elegance which we are just starting to see. RJW
