# AnyServiceMap

A widened Effect Context accepted as an already-built dependency.

## Signatures

```ts
export type AnyServiceMap = Context.Context<any> | Context.Context<never>;
```

## Why

Callers can provide existing services without forcing them through Layer acquisition.

## Ownership and lifetime

This alias is compile-time only. A supplied Context is borrowed as already-built services; Matcher does not acquire or finalize those service values.
