//! TDD Test for handle_analyze_provability refactoring (Sprint 79)
//!
//! Following Toyota Way TDD principles:
//! 1. Write test FIRST (Red)
//! 2. Make it pass (Green)
//! 3. Refactor to reduce cognitive complexity from 44 to ≤10 (Refactor)
//!
//! Current: Cognitive complexity 44, Cyclomatic complexity 13
//! Target: Cognitive complexity ≤10, maintain functionality
