Validation status

Upgrade notes

• Public runtime APIs use Result (not throws) for engine execution flows.
• README snippets were updated to use Result-based handling.
• No breaking parity changes in v2/v3 model semantics; release is additive around API ergonomics and documentation.

Known constraints

• Parity checks require local access to the JavaScript engine checkout.
• Demo datasets are bundled for offline trials and intended for smoke/UX onboarding, not production signal quality assessment.
