This is the name of this specific stage within the QoS-definition state machine, drawn from a fixed enumeration of the stages that workflow can pass through. Deleting the policy from the fabric happens as a short ordered sequence of named steps — e.g. removing it from fabric A, then fabric B — and this record is one of those steps, tracked separately so a stall or retry can be pinpointed to the exact stage it happened at. Example stage names include things like 'ConfigFabricA' or 'ConfigFabricB', letting an admin see exactly which fabric interconnect a rollout is currently working on.
