intentguard/src/trust-debt-final.js

Mathematical foundation for AI trust measurement. Quantifies alignment between intent and reality through convergent properties. The only system that makes AI trust measurable, insurable, and legally defensible.

/**
 * TRUST DEBT FINAL - DETERMINISTIC IMPLEMENTATION
 * 
 * Calculates Trust Debt between documentation (Intent) and implementation (Reality)
 * using matrix analysis and keyword correlation.
 * - Prefix letters (A,B,C,D,E) maintain parent ordering
 * - Colors shade from parent base color
 * 
 * ShortLex Ordering Example:
 * A📚 (length 3)
 * B🎯 (length 3) 
 * C📏 (length 3)
 * D🎨 (length 3)
 * E✅ (length 3)
 * A📚.1 (length 5) - First A child
 * A📚.2 (length 5) - Second A child
 * A📚.3 (length 5) - Third A child
 * B🎯.1 (length 5) - First B child
 * ... etc
