🌌 T_μν ≥ 0 Matter Distribution Configuration Using Bobrick-Martire Geometry Shaping

Research-stage positive matter assembly approach providing controlled T_μν ≥ 0 matter distributions through LQG-enhanced Bobrick-Martire geometry shaping. Integrates Loop Quantum Gravity spacetime discretization, stress-energy tensor control, and quantum geometric field generation for model-dependent positive matter configuration; safety validation methods are documented, but independent certification is not claimed.
