title Support assistant — L2 Topology
' VIEWPOINT: Topology — what shape is this, and who routes? The orchestration
' spectrum runs scripted flow -> router -> supervisor -> swarm -> solo. This is
' a ROUTER: one classifier picks a specialist on a guard the author fixed.
' DONE WHEN: the position on the spectrum is declared and every route is typed.
'
' Rel_Expr is a deterministic guard, Rel_LLM is the model's judgement, and a
' bare Rel is an unguarded route.
