title Incident response — swarm topology

' VIEWPOINT: Topology, choreographed end. There is NO author-defined path here:
' peers decide at runtime who takes over. Read every Handoff as "MAY hand to",
' never "then" — the renderer lays this out with a force algorithm precisely so
' the y-axis cannot be mistaken for a sequence.
' DONE WHEN: no edge in the mesh implies an order the runtime does not enforce.
'
' Delegate hands work down and EXPECTS IT BACK; Handoff means a peer takes over
' and does not return. A swarm is made of the second kind.
