set_resource_standby_mirror

Switch the live mirror into a resource's standby on or off, so a failover lands members in a channel that already holds the content.

Purpose

When on, every post made in the channel is copied into the standby as it is made. Only a channel can be mirrored (a group cannot), the resource must keep a standby, switching on needs the Growth plan, and only the project owner may do it. Returns the standby as it now stands. The REST twin is PATCH /v1/projects/{project}/resources/{resource}/standby.

Required ability

project-recovery:update

Failure modes

VALIDATION_FAILED — a group, no standby, the plan lacks the prevention features, or the token is not the project owner's.
RESOURCE_NOT_FOUND — resource_id is not a resource the token can see.
AUTHENTICATION_REQUIRED — no authenticated user on the request.
TOKEN_MISSING_ABILITY — token lacks project-recovery:update.

get_resource_standby — read the switch.
