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 Fg. 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.
