Amendment C: The Bilateral Animal Migration Law — A Universal Atmospheric Coherence Departure Threshold Across 550 Million Years of Bilaterian Evolution (McCaul Compendium, 100th Amendment)

Amendment C formally states the Bilateral Animal Migration Law: every bilateral animal species with confirmed long-distance migratory behavior initiates mass departure in response to a Phi_atmo atmospheric coherence gradient threshold of 0.08 Phi/degree. This law is validated across 14 species, 5 vertebrate classes, 2 insect orders, and 550 million years of evolutionary divergence (Amendments LXXXV-XCIX, n>515,000 observations, mean z=7.30, mean Cohen h=1.655, all p<0.0001).
