A conforming model must support work package, deliverable, implementation event, plateau and gap, where a work package is a defined set of actions bounded by time and resource limits, a deliverable is its precisely defined result, an implementation event is a related state change, and a plateau is a relatively stable architecture state held for a limited period, so a gap can be stated as the difference between two plateaus.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
