+//! Solder Cortex Integration for SOLPRISM
+//!
+//! Adds conviction scoring to enhance agent reasoning verification.
+//! Before trusting an agent's reasoning proof, verify their wallet has
+//! cross-domain conviction (active in DeFi + prediction markets).
+//!
+//! Demo: http://76.13.193.103/
+//! GitHub: https://github.com/metalmcclaw/solder-cortex
