Clockwork 2.0 Migration

Clockwork 2.0 removes the redundant ClockworkError.is() type guard. Runtime malformed-event diagnostics now warn during development before ignoring invalid input.

Replace ClockworkError.is() with instanceof

The static ClockworkError.is() method is removed. Use instanceof ClockworkError to narrow unknown errors.

// Before
if (ClockworkError.is(error)) {
  console.error(error.code, error.details);
}

// After
if (error instanceof ClockworkError) {
  console.error(error.code, error.details);
}

Check malformed event dispatches during development

actor.send() still ignores malformed runtime values, but now writes a development warning when the value is not an object with a string type. Valid event objects without a transition remain silently ignored. TypeScript callers already receive compile-time checking; validate untrusted JavaScript or external input before dispatching it.
