answering_policy_closed_steps_required
A mobile schedule edit gave a number's answering policy business hours or holiday dates, but the policy carries no closed-step route to answer with when closed. Add a closed-step route before scheduling hours.

Every non-2xx response is an RFC 9457 application/problem+json body. The type URI below is stable and machine-matchable, so branch on the final path segment (the code) and treat the status as redundant confirmation. See the error-handling guide.
