# Versioned.Service

Creates a Context-backed Versioned service facade and Layer constructor.

## Signatures

```ts
export declare function Service<Self, E1 = never, A2 = never, E2 = never, A3 = never, E3 = never>(): <const Id extends string>(id: Id) => Versioned.Class<Self, Id, E1, A2, E2, A3, E3>;
```

## Why

Creates an Effect service tag that exposes current reads, pushed updates, and versions through
one Layer-provided state dependency.

## Ownership and lifetime

Calling Service is pure. The generated make Layer captures required environments and owns the
provided state for the Layer Scope.

## Examples

```ts
import { Effect } from "effect"
import * as Fx from "@typed/fx/Fx"
import * as Versioned from "@typed/fx/Versioned"

class Status extends Versioned.Service<Status, never, string, never, string>()(
  "example/Status"
) {}

const StatusLive = Status.make(
  Effect.succeed(1),
  Fx.succeed("ready"),
  Effect.succeed("ready")
)
```
