  Microsoft Graph / Teams does not use test card numbers or magic identifiers.
  Its sandbox model is a real but disposable Microsoft 365 developer tenant plus
  a hosted request runner (Graph Explorer) with a shared sample tenant. Never
  invent tenant ids, tokens, or object ids — provision your own.
environments:
  - name: Microsoft 365 Developer Program
    type: sandbox-tenant
    url: https://developer.microsoft.com/en-us/microsoft-365/dev-program
    description: >-
      A free, renewable Microsoft 365 E5 developer tenant, optionally
      pre-provisioned with sample users, teams, channels, and content. Gives you
      a real Entra ID tenant to register apps against and exercise Teams Graph
      APIs without touching production.
    notes:
      - Separate tenant id / admin account issued per developer; no shared secrets published.
      - Sample data pack seeds users, groups, teams, and SharePoint content.
  - name: Graph Explorer
    type: hosted-request-runner
    url: https://developer.microsoft.com/en-us/graph/graph-explorer
    description: >-
      Browser-based tool to issue authenticated Microsoft Graph requests. Signed
      out, it runs against a shared demo tenant with sample Teams data; signed
      in, it runs against your own tenant with consented scopes.
    notes:
      - Demo-tenant sample data is Microsoft-hosted and read-oriented.
test_vs_live:
  separation: tenant-scoped
  note: >-
    There is no test/live key prefix. Isolation is by tenant: a developer
    (sandbox) tenant vs. a production tenant. Same endpoints and OAuth flows for
    both; the token's tenant determines the environment.
