Outside of the reconciliation loop — from a status listener or a background task, or about an object
other than the primary — use the unbound form from
`RegisteredController#eventRecorder()`, which is scoped to the controller rather than to a
reconciliation:
To record events differently — assemble them another way by extending `DefaultEventRecorder`, or
send them somewhere else entirely — plug in an `EventRecorder` of your own for the whole operator:

```java
EventRecorder recorder = registeredController.eventRecorder();
recorder.record(someOtherResource, EventRecord.normal("Noticed", "something happened"));
var operator = new Operator(o -> o.withEventRecorder(new MyEventRecorder()));
```

A custom recorder is shared by all controllers, so it must be stateless and thread safe: the
`Context` of the reconciliation an event is recorded from is passed to it per call, as in
`EventRecorder#record(EventRecord, Context)`. `context.eventRecorder()` is the same recorder, already

State the error-handling requirement for custom recorders.

The SDK does not enforce best-effort recording around a custom recorder. If its sink throws, the exception can fail reconciliation.

Suggested fix 

 bound to that context. Without a custom recorder, every controller records its events through a
 `DefaultEventRecorder` of its own.
 
+Custom recorders must log and swallow recording failures, including through their context-bound view.

Review comment at @docs/content/en/blog/releases/v5-6-release.md around lines 100 - 102:
Update the custom recorder documentation near `EventRecorder#record` to state that recorder implementations must log and swallow recording failures, including when invoked through the context-bound `context.eventRecorder()` view.
