Highlights
- Drop-in
WorkflowEngineprovider that preserves the DSH workflow API and lifecycle events. - Fresh QuickJS realm and worker for each run, with no ambient Node.js capabilities.

- Heap, stack, interrupt-fuel, wall-time, source, result, agent-request, concurrency, fan-out, and total-call controls.
- Bounded cancellation and disposal with forced worker termination and paired agent events.
- English and Chinese documentation, threat model, compatibility matrix, example workflow, and benchmark harness.
Validation
- 41 automated tests, production-bundle smoke tests, and package-surface validation.
- CI passes on Node.js 22.19 and 24 across Ubuntu and Windows.
- The attached npm tarball contains 31 files and can be installed directly into a DSH profile.
