summary: >-
  Outpost publishes a separate staging environment for the Partner / Hosted
  Onboarding API and documents a "Testing & Rollout" flow for the Tax of Record
  integration. No test card numbers, magic test identifiers, or hosted test
  tokens were published in the static docs (Outpost is a merchant-of-record /
  tax layer that sits behind the merchant's own PSP, so payment test values come
  from the PSP, not Outpost).
