/**
 * BCBA Skill Integration Tests
 * ═══════════════════════════════════════════════════════════════
 *
 * Tests that the BCBA behavioral principles are enforced across
 * ALL skills when they interact. The BCBA skill is the brain —
 * every other skill must operate within its behavioral boundaries.
 *
 * Principle: "The child's voice is sacred. The system learns to
 * AMPLIFY their communication — never to override, replace, or
 * restrict it."
 *
 * These principles apply universally — to code reviews, customer
 * reports, translations, deployments, and agent behavior.
