# isKsuid

Tests whether a string has the KSUID encoding shape.

## Signatures

```ts
export declare const isKsuid: (value: string) => value is Ksuid;
```

## Why

Runtime refinement restores trust after serialization has erased the TypeScript brand.

## Ownership and lifetime

This pure predicate acquires no resources and retains no input.

## Examples

```ts
import { isKsuid } from "@typed/id/Ksuid"
isKsuid("0ujtsYcgvSTl8PAuAdqWYSMnLOv")
```
