/**
 * Swagger / OpenAPI document metadata tests (R5.3).
 *
 * These tests verify OpenAPI decorator metadata on the AcadeDoc controllers
 * without booting a full NestJS application (avoids ESM module chain issues
 * with prosemirror/collaboration utilities in the test environment).
 *
 * Strategy:
 * - Import only the controller class (not its full DI tree)
 * - Use `Reflect.getMetadata` to inspect @nestjs/swagger decorator metadata
 * - Use `DocumentBuilder` standalone to verify tag/security configuration
 */
