nested depth 5 multi branch

// ============================================================================
// CHAOS MODE: Depth 5 with Multiple Branches
// ============================================================================
// This tests the FULL complexity:
// - 5 levels deep
// - Multiple branches at each level (ok/error)
// - Error handling propagation
// - Should expose ALL the bootstrap bugs at once!
// ============================================================================
