//! Jidoka Automated Gates (Section 7)
//!
//! Implements JA-01 through JA-10 from the Popperian Falsification Checklist.
//! Focus: CI/CD circuit breakers, automated quality enforcement.
//!
//! # Jidoka Principle
//!
//! "Automation with human intelligence" - The CI/CD pipeline must detect
//! abnormalities and stop automatically before human review begins.
