title Support assistant — exit map

' VIEWPOINT: Exit map — every way out, and where each one goes. Exits are the
' metric surface: containment is computed from them, and it is the number the
' business asks about. All eleven types exist in the notation so the renderer
' can list the ones you did NOT model — a drawing has no opinion about what
' isn't on it. One macro each, so the set is discoverable by typing "Exit_":
'   Exit_Complete   Exit_AgentTransfer  Exit_Human     Exit_Guardrail
'   Exit_Refusal    Exit_Budget         Exit_Loop      Exit_Context
'   Exit_Interrupt  Exit_Retries        Exit_Timeout
' A bare Exit() is one whose type has not been decided yet, and the renderer
' says so rather than guessing.
' DONE WHEN: all eleven have been considered, and the omissions are deliberate.
