J3 Atomic v7.3 High-Res — ZERO-TRUST Multi-Hardware Validation
=============================================================================

Purpose:
    Reproducible technical report for multi-hardware validation:
        B_CALC J3 HR -> volume / shape / elasticity -> experimental comparison

IMPORTANT ZERO-TRUST:
    This script does NOT hide the calculation in phrases. For each channel it displays:
        1) the declared numerical input;
        2) the total energy B_TOTAL = A * B_CALC;
        3) the verification formula;
        4) the numerical substitution;
        5) the J3 - EXP difference;
        6) the relative difference;
        7) the normalized score = |delta| / tolerance;
        8) the PASS/FAIL verdict.

    The script does NOT perform:
        - optimization;
        - regression;
        - least-squares;
        - random search;
        - parameter adjustment;
        - changing J3 or EXP values during runtime.

Correct observation for external audit:
    The R_J3, AXIS_J3 and E_GMR_J3 values are treated here as J3 High-Res outputs
    declared, associated with the B_CALC energy. The script transparently verifies their consistency
    with the independent experimental hardware.
