Wiring moves out of deps.py::langgraph_runtime into app/composition.py::build_domain_services, so the rule the assembly owns -- a memory database backend yields no services and the routes answer 503 -- is an assertion in tests/test_composition.py instead of a comment inside the lifespan.

"""Composition-root tests -- the rules the wiring itself owns.

``build_domain_services`` was extracted into a pure function precisely so

these rules are assertions instead of a comment inside the lifespan:

a ``database.backend: memory`` deployment gets no services (the dependency

providers translate that into 503).
