# partition

Partition entries.

## Signatures

```ts
export declare const partition: {
    <K extends string, V>(predicate: (value: V, key: K) => boolean): <E, R>(ref: RefRecord<K, V, E, R>) => RefSubject.Computed<[
        Record.ReadonlyRecord<K, V>,
        Record.ReadonlyRecord<K, V>
    ], E, R>;
    <K extends string, V, E, R>(ref: RefRecord<K, V, E, R>, predicate: (value: V, key: K) => boolean): RefSubject.Computed<[
        Record.ReadonlyRecord<K, V>,
        Record.ReadonlyRecord<K, V>
    ], E, R>;
};
```

## Why

Partition entries. The operation remains attached to the RefSubject's versioned state boundary.

## Ownership and lifetime

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