ISCO Shift Scaling
δr_ISCO ~ O(g³/(GM)²)
PASS — C2_isco_shift_scaling

What this does prove
The innermost stable circular orbit's shift from the Schwarzschild value scales cubically with the core parameter g, matching the predicted exponent (fitted: 3.00024).
What this does not prove
That this scaling is observationally distinguishable with current instruments, or what numerical value of g (if any) is physically realized.
