• State of the composition elements
• State of the overall composition is derived from the composition element states
• Admin state/Running state
• When all the elements are fully up and configured, the go to state Passive, when all elements are in Passive, the full composition goes to Passive
• Error states: Are they parallel sates or part of the same state?
• There should “it didn’t work” states like “Passive-Error” or “Run_Error” (names to be decided later)
• Describe what the “Running” state means and what the participant should do in Passive->Running and Running->Passive transitions.
• Say a K8S service crashes, how do we feed that back? Running_Error. The state of the POD is only checked during startup. It is not periodically checked. There should be supervision.

Discuss priming and what the relationship is with this.
