# isBipartite

Check if the graph is bipartite (undirected only).

## Signatures

```ts
export declare const isBipartite: <N, E, Err, R>(ref: RefGraph<N, E, "undirected", Err, R>) => RefSubject.Computed<boolean, Err, R>;
```

## Why

Check if the graph is bipartite (undirected only). The operation remains attached to the
RefSubject's versioned state boundary.

## Ownership and lifetime

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