      The current user. Sign-up and sign-in happen in WorkOS AuthKit, which
      issues the access tokens this API accepts.
  - name: organizations
    description: >-
      Organizations the caller belongs to. Every authenticated request acts
      inside exactly one organization — the one its access token names — so
      these routes address it as `current`.

      Long-lived credentials for callers that cannot hold an AuthKit session —
      agents, SDKs, CI. A key is accepted wherever an access token is, and acts
      with the role its creator holds when the request arrives.

      Create and edit isolated provider environments. Each environment contains
      behavioural twins from the `twins` package.
