`@playstack/licensing-issuer` turns application-owned purchase policy into signed, distributable licenses. It does not process payments, expose routes, send mail, or decide product terms.

```ts
import { createLicensingIssuer } from '@playstack/licensing-issuer'

const issuer = createLicensingIssuer({
  persistence,
  authorizer: applicationLicensePolicy,
  distribution: transactionalDeliveryOutbox,
  signer: kmsBackedEd25519Signer,
  secrets,
  responseVault,
  events,
  clock,
  ids,
})
```

Activation codes are returned once and stored only as keyed digests. Activation and refresh responses are sealed for exact idempotent retries. Private key custody remains behind `LicenseSignatureSigner`; `LicenseResponseVault` must encrypt response material at rest.

Use `@playstack/licensing-issuer/prisma` for the managed PostgreSQL contract. The application owns migrations, entitlement-to-license policy, HTTP routes, distribution delivery, and key management.

## API entry points and requirements

Reference snapshot: `@playstack/licensing-issuer@0.1.0-beta.1`. Import only the entry point your runtime needs. Paths below are relative to the installed package; use **Go to Definition** in your editor to inspect exact parameters, return types and overloads. Do not import the declaration-file paths directly.

| Public entry point | Declaration file |
| --- | --- |
| `@playstack/licensing-issuer` | `./dist/index.d.ts` |
| `@playstack/licensing-issuer/errors` | `./dist/errors.d.ts` |
| `@playstack/licensing-issuer/testing` | `./dist/testing.d.ts` |
| `@playstack/licensing-issuer/prisma` | `./dist/prisma.d.ts` |
| `@playstack/licensing-issuer/playstack.artifacts.json` | No TypeScript declaration (asset or metadata export). |
| `@playstack/licensing-issuer/package.json` | No TypeScript declaration (asset or metadata export). |

Node.js engine requirement: `>=20`. This is not a claim that every entry point works in browsers or Workers.

### Peer dependencies

This package declares no peer dependencies. Its ordinary dependencies are resolved by the package manager.

For a complete first program, start with [Getting started](/docs/getting-started). For API lookup and partial-example conventions, see [Reading the reference](/docs/packages#reading-the-reference). Provider failures, lifecycle requirements and application responsibilities remain described in the guide above; types alone do not establish production safety.
