Menger Sponge Fractal Addressing System (Verified Lean Specification)
This implementation follows the formal specification in:
0-Core-Formalism/lean/Semantics/Semantics/MengerSpongeFractalAddressing.lean
The Lean module provides:
- Menger sponge fractal addressing for PIST manifold
- |P_occ| = ρ_occ · N^{d_H}
- d_H ≈ 2.7268 (Hausdorff dimension)
- address(x,y,z) = menger_hash(x,y,z) ⊕ fractal_offset
- Reduces state space from 262,144 to ~84,000 positions (68% reduction) for N=64
This Python shim provides:
- JSON serialization for Menger sponge lattice state
- Result wrapping for Lean function calls
- No logic (all logic defined in Lean specification)
