//! # Application 10: Pre-AGI Containment Substrate
//!
//! A substrate where intelligence can increase only if coherence is preserved.
//!
//! ## The Deep Problem
//! How do you build a system capable of general intelligence that
//! cannot undergo uncontrolled recursive self-improvement?
//!
//! ## Δ-Behavior Solution
//! Intelligence and capability can grow, but only along paths that
//! preserve global coherence. Capability-coherence is the invariant.
//!
//! ## Exotic Result
//! A system that can become arbitrarily intelligent but cannot
//! become arbitrarily dangerous.
