// Source: Phase 3 SDOC-01..06 composite verify gate smoke test.
//
// Spawns `node scripts/verify-phase-3.mjs` end-to-end against committed Phase 3
// artifacts. Asserts:
//   - exit 0
//   - stdout matches /OK \(\d+ steps green\)/
//   - all 14 canonical step labels appear in stdout in order
//
// Usage: node scripts/verify-phase-3.test.mjs
//        OR: pnpm test:verify-phase-3
// Exit: 0 on success, 1 on any assertion failure.
