x-note: Fermyon publishes the Cloud API contract without a single operationId (verified against https://raw.githubusercontent.com/fermyon/cloud-openapi/main/swagger.json
  on 2026-09-09). These operationIds are computed deterministically from HTTP method + path by API Evangelist and
  are NOT names Fermyon publishes. They are kept in this overlay rather than written into the spec so the provider
  contract stays unmodified.
