# RefCause.reasons

Get the reasons array of the current state of a RefCause.

## Signatures

```ts
export declare const reasons: <E, Err, R>(ref: RefCause<E, Err, R>) => RefSubject.Computed<ReadonlyArray<Cause.Reason<E>>, Err, R>;
```

## Why

Get the reasons array of the current state of a RefCause. The operation remains attached to the
RefSubject's versioned state boundary.

## Ownership and lifetime

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