Without a version in the path, the call answers on the program’s latest release, resolved once; the response’s `releaseVersion` and `bundleId` name what answered. A program with no release returns 404 `release_not_found`. ## OpenAPI ````yaml /openapi.json get /rsl/{id}/contract openapi: 3.0.3 info: title: Effective API version: 2.0.0 description: The public Effective REST API.
