"""Route-level tests for the rulebooks blueprint.

Mirrors the structural-tests pattern in tests/test_events_routes.py:
covers blueprint registration, callable handlers, and service-signature
contracts. Full HTTP integration requires a live DB and auth machinery
that the unit-test environment doesn't provide.
