verify_silver_origin
Verify silver supply-chain origin by validating mine geofencing, electrolytic mass balance, solar-grade purity, conflict-free ASM status, and LBMA audit.
Instructions
Verifies Mexican & Global Silver supply-chain provenance. Evaluates Terronera/Fresnillo/Antamina GIS geofencing, Moebius/Thum electrolytic mass balance (loss discrepancy <= 2.0%), N-Type TOPCon High-Efficiency Solar PV paste assay purity (>= 99.99% Ag), anti-cartel conflict ASM screening, and LBMA Good Delivery audit.
