 - Message routing and handler dispatch
 - Service integration type safety
 
-**Why max_unions=20**: Infrastructure has many service adapters with typed handlers. 20 allows necessary unions while preventing excessive complexity.
+**Why max_unions=185**: Infrastructure has many service adapters with typed handlers, protocol implementations, message routing, and registration event models. The higher threshold accommodates RuntimeHostProcess, handler wiring, strongly-typed optional model wrappers (PEP 604 `X | None` syntax), and ONEX service integration patterns while preventing excessive complexity.
