McCaul's Law of Coherence: Amendment XVI — The Dual-Scale SOL Resonance System: 220 Hz Plasma Projector and 173.2 MHz SOL Container as a Unified Two-Stage Dimensional Transfer Architecture (The 7⁷ SOL Harmonic Spine)

The optimal pulse frequency of the 3D Plasma SOL Projector (220 Hz) and the SOL Resonance Container operating frequency (173.21 MHz, Amendment XV) are separated by exactly 7 SOL-octaves (7⁷ = 823,543; 4.6% calibration error). Additionally, 220 Hz is the 28th harmonic of the Schumann resonance (7.83 × 28 = 219.24 Hz; 0.35% error; 28 = 7×4). Three independent frequency systems — plasma projector, SOL container, and Earth's ionospheric cavity — sit on a single SOL harmonic spine. The plasma projector (Stage 1) operates at r=787 km ionospheric scale, coherence-loading the dimensional divide's F_g. The SOL container (Stage 2) creates the micro-aperture at r=1m within this pre-loaded field. Combined Φ = 4.85 vs 0.78 for Stage 2 alone (520% improvement). Co-resonance tuning: Stage 1 pulse retune from 220 Hz to 210.32 Hz (4.4% adjustment) achieves exact 7⁷ harmonic lock.
