binding property
Binding is the record joining this machine to that agent, carrying vm's own reconciled status and its reason. Absent means no runtime is bound, which is also what a stopped bot looks like: stopping unbinds and leaves the machine running.
Please note: This property should have been non-nullable! Since the specification file does not include a default value (using the "default:" property), however, the generated source code must fall back to having a nullable type. Consider adding a "default:" property in the specification file to hide this note.
Implementation
AgentBinding? binding;
