    Control-plane Connect RPCs over HTTP with ProtoJSON request and response
    bodies.

    description: |-
      Manages the current user's application-owned personal access tokens.
       External sign-in is required; personal and execution tokens cannot manage keys.
  - name: BillingAccount
    description: >-
      How a workspace pays: its prepaid balance, topped up through the payment
      processor and spent
       by its usage.
  - name: Image
    description: >-
      The image registry: OCI distribution over its storage, whose formats are
      its own. The
       control plane serves it to users, admitting each only to their workspace's repository, and
       forwards to the OCI registry. Manifests and blobs are addressed by digest and never
       replaced; tags name manifests.
  - name: ImageBuilder
    description: >-
      Builds Images from image specs, and runs their install steps, each adding
      layers to its
       parent image, and package builds, each one pinned package's layer on its base, which
       install steps merge rather than install. The control plane serves `SubmitImageBuild`
       and `WaitImageBuild` to users, and forwards them to the scheduler's, which imports each
       image spec's base through the OCI registry, places each install step and package build on a
       node that builds, and tags the image it built in its workspace's repository. Those nodes
       serve the steps to the scheduler, by the scheduler's certificate, and run each in the
       sandbox the scheduler placed it in.
  - name: Policy
    description: >-
      Resource access policies evaluated by the application's Cedar authorizer.
      A policy belongs to
       the workspace of the credential that created it and governs only that workspace and what it
       owns; deployment-wide grants belong to the operator's policy.
  - name: Run
    description: >-
      Submits and observes product Runs, their Calls, and the Calls' Attempts.
      Every Run
       owns one rooted Call tree.

  - name: Workspace
    description: >-
      The workspace a request's credential is bound to, and its members. A
      session starts bound
       to its user's workspace and may switch to another the user belongs to; an API key stays bound
       to the workspace it was created in. Requests act in the bound workspace.
