## Validation prompt

Use this to decide whether a fired diagnostic is real or a false positive.

Confirm the reported code matches Effect cleanup does not match its event listener. Check the framework context and diagnostic message before suppressing it.

## Fix prompt

Use this once validation confirms the diagnostic is real.

Pass the same callback binding and capture flag to `addEventListener` and `removeEventListener`, or abort the registration's local AbortController during cleanup.
