# hasDies

Check if the current state of a RefCause has a Die.

## Signatures

```ts
export declare const hasDies: <E, Err, R>(ref: RefCause<E, Err, R>) => RefSubject.Computed<boolean, Err, R>;
```

## Why

Makes has dies a live projection of the cause; consumers can sample it now or observe it without
copying the source state.

## Ownership and lifetime

The has dies view retains no independent state. An Effect read samples the source once; Fx
observation follows later pushes and its observing Scope owns subscription cleanup.
