/*
 * ═══════════════════════════════════════════════════════════════════════════
 * UNIFIED BIGG + FUDGE10 EMPIRICAL VALIDATION WITH 4096-BIT PRECISION
 * ═══════════════════════════════════════════════════════════════════════════
 *
 * PURPOSE: Port complete empirical validation from EMPIRICAL_VALIDATION_ASCII.c
 *          with enhanced 4096-bit arbitrary precision arithmetic (APA)
 *
 * CRITICAL ASSUMPTIONS:
 *   - Special Relativity is wrong (variable c is ALLOWED)
 *   - General Relativity is wrong (variable G is ALLOWED)
 *   - Constants are scale-dependent and emergent
 *
 * VALIDATION TARGETS:
 *   1. BigG: Reproduce Pan-STARRS1 supernova fit (1000+ Type Ia supernovae)
 *   2. Fudge10: Verify 200+ CODATA constant fits
 *
 * ENHANCEMENTS:
 *   - 4096-bit mantissa for extreme precision
 *   - Handles φ^{-159.21} × 1826^{-26.53} without underflow
 *   - Range: 10^{-1232} to 10^{+1232}
 *   - All core calculations in APA, conversion to double only for output

4096-BIT APA KEY ADVANTAGES:
---------------------------------------------------------------------------
  * Handles 1826^(-26.53) = 10^(-85) without underflow
  * Computes phi^(-159.21) = 10^(-32) with full precision
  * Range: 10^(-1232) to 10^(+1232) vs double's 10^(-308) to 10^(+308)
  * All intermediate calculations maintain 4096-bit precision
  * Only final output converted to double for display
