This is a free-text description field (rmtErrDescr) on an ObservedFsm object, holding whatever descriptive text was set for the FSM task that tracks state transitions for an Observed object under the observe framework. An admin uses it to record human-readable context about that specific ObservedFsm instance so its purpose is clear without having to infer it from IDs alone. For example, an admin auditing ObservedFsm objects would read this field to see the notes attached to one particular instance rather than a generic label shared by all of them.
