/**
 * Tests for expert/expert-cqrs piece parallel review structure.
 *
 * Validates that:
 * - expert and expert-cqrs pieces load successfully via loadPiece
 * - The reviewers movement is a parallel movement with expected sub-movements
 * - ai_review routes to reviewers (not individual review movements)
 * - fix movement routes back to reviewers
 * - Aggregate rules (all/any) are configured on the reviewers movement
 * - Sub-movement rules use simple approved/needs_fix conditions
