Summary & Key Takeaways ​

• refresh(target) now returns a promise that resolves when the target's re-ask has settled.
• This allows for awaiting the completion of a refresh operation, improving async flow control.
• Failed re-asks now reject the promise, enabling better error handling in actions.
• Disposed nodes are now explicitly refused by updateIfNecessary, preventing certain bug classes.

Our Commentary ​

This refresh promise is a subtle but powerful addition to Solid's reactivity model. It gives developers more granular control over async operations, which is always welcome. I appreciate the focus on ensuring quiescence, not just flight identity. It feels like a natural evolution for a framework so deeply rooted in fine-grained reactivity.
