description: 'Forecast is held.

It is empty by default, so the v2 rollout alone never exposes Forecast. A company off the list receives the same hidden-resource 404 contract as one for which the surface does not exist.

The auth-context featureFlags key `arApItems` mirrors exactly that conjunction, resolved server-side, so the customer shell hides the Receivables/Payables nav and pages instead of offering menu entries these routes 404. Default is FALSE for every company while the list is empty or the conversion has not run.

description: 'Promoted. The deployment this contract describes runs ONBOARDING_V3_QA_ONLY=false, so none of the onboarding-v3 auth, pricing, or setup paths below requires X-Median-App-Surface: qa. An unmarked request is served and reaches ordinary authentication, so an unauthenticated call now answers 401 rather than the hidden-resource 404. Mounting is still conditional: with ONBOARDING_V3_ENABLED false every path below returns the hidden-resource 404 before body parsing or authentication. The header stays defined and is still honoured, because a deployment left at ONBOARDING_V3_QA_ONLY=true keeps requiring it on every path below and 404s unmarked traffic; setting that flag back to true is the rollback. On either setting the header is a pre-company bundle marker, never tenant authorization.
