mobx-react-lite Observer Subscription Boundary Behavior

MobX 6 and mobx-react-lite Observer Integration

The integration relies on MobX 6 observable state within React function components using mobx-react-lite observer.

Subscription Registration Scope

Reactivity is established solely when observable properties are read during the component function execution phase of a React render.

What is the precise boundary for subscription registration within this integration?

• Do observable reads within event handler callbacks register subscriptions for the component's render cycle?
• Does an observable read inside a React useEffect hook establish a persistent subscription tied to the component lifecycle?
