# ComputedTypeId

Runtime symbol identifying read-only Computed values.

## Signatures

```ts
export declare const ComputedTypeId: unique symbol;
```

```ts
export type ComputedTypeId = typeof ComputedTypeId;
```

## Why

Provides stable runtime identity for Computed values without relying on classes or a renderer.

## Ownership and lifetime

This declaration performs no acquisition and retains no resources. Implementations preserve
source errors, services, and lifetime.
