medication_catalog — events

The module emits no events. Catalog entries are reference data; nothing else needs to react to their lifecycle asynchronously.

Event	Handler	Mode
clinic.created	on_clinic_created → seed_medications	own session (non-transactional)

Why non-transactional: clinic.created is published after the signup transaction commits and without a db= session (the bus raises RuntimeError if a transactional handler receives no session). This is the exact precedent of the catalog module's seeder (issue #183): the handler opens its own session via async_session_maker, seeds idempotently, commits — and logs failures instead of raising, since a seeding gap must never break clinic signup. POST /medication_catalog/seed repairs an empty list on demand.
