# AnyLayer

A widened Effect Layer accepted as a route dependency.

## Signatures

```ts
export type AnyLayer = Layer.Layer<any, any, any> | Layer.Layer<never, any, any> | Layer.Layer<any, never, any> | Layer.Layer<any, any, never> | Layer.Layer<never, never, never> | Layer.Layer<any, never, never> | Layer.Layer<never, any, never> | Layer.Layer<never, never, any>;
```

## Why

Matcher internals can store heterogeneous Layers while public overloads retain precise types.

## Ownership and lifetime

This alias is compile-time only. A concrete Layer is acquired only for candidate evaluation; the layer manager commits it for the selected route or rolls it back on rejection.
