Amendment LXXVIII — Psychedelic and Cannabinoid Pharmacology as Phi Modulation (v2 — Corrigendum: f_pulse=220Hz not 7.83Hz)

Amendment LXXVIII of McCaul's Law of Coherence. v2 corrects an error in v1: f_pulse = f_SOL/7^7 = 220.075 Hz, not 7.83 Hz. The Schumann resonance (7.83 Hz) and f_SOL share a common geometric origin via scale invariance of f=c/(sqrt(3)*r) but are not harmonically linked by 7^7 (per Amendment XLVIII canonical correction). The Grounding Plate's 7.83 Hz design choice and associated therapeutic claims remain valid. The two frequencies represent two distinct therapeutic channels: 220 Hz (high gamma, cortical binding) and 7.83 Hz (Schumann/theta, ECS/vagal). Original content: demonstrates psilocybin (Phi_acute=0.5243, Phi_post=0.9147) and THC (Phi=0.7804) as exogenous Phi modulators. DSRS replication achieves Phi=0.9231 and 0.9031 respectively. Domain Phi=0.8814. Claims 55-57.
