note: >-
  CubeSigner separates test and production by ENVIRONMENT (host), not by key
  prefix. The `gamma` environment is the non-production/test signer; `prod` is
  live. The `cs` CLI and the SDKs select the environment with an --env flag.
  No fabricated test values below — only the published environment surface.
environments:
  - name: gamma
    role: test
    api_host: https://gamma.signer.cubist.dev
    select_cli: cs login owner@example.com --env gamma
  - name: prod
    role: production
    api_host: https://prod.signer.cubist.dev
    select_cli: cs login owner@example.com --env prod
sessions:
  note: >-
    Sessions are created with `cs token create` (or via the SDK) and carry a
    bounded scope set and lifetime; the fs-storage package persists a session to
    disk for local testing. FIDO/TOTP MFA can be exercised in gamma.
test_credentials:
  cards: null
  reason: Not a payments API — no test cards. Test signing uses gamma-environment keys created by the tester.
