# RefSubject.CurrentComputedBehavior

Selects whether a computed Fx observes only its current value or also follows later pushes.

## Signatures

```ts
export declare const CurrentComputedBehavior: Context.Reference<"one" | "multiple">;
```

## Why

`"multiple"` (the default) emits the current value and then follows distinct source pushes.
`"one"` emits only the current value. Hydration temporarily uses `"one"` when it must resolve a
single server value without leaving a live observation running.

## Ownership and lifetime

This is an Effect Context reference with a default value, not mutable global state. Supplying a
value changes computed observation only in the provided Effect context; the observing Scope
still owns any subscription created by `"multiple"`.
