Owner-only OpenAPI 3.1 document with one method-specific path entry per route. requestBody schema comes from route.inputSchema; the 200 response schema wraps route.outputSchema as `{ ok: true, value }`. Apps that do not declare `routes` get an empty `paths: {}` document.

<Operation source="reference" id="get-app-openapi" />
