"""Integration tests for release-dates/certifications (section 17,
additive): TMDb's release_dates/content_ratings blocks were already being
fetched via append_to_response, but dropped at the normalizer step -- every
downstream layer (ingestion write, repository read, schema, service) was
unbuilt. Mirrors test_movie_ingestion.py/test_series_ingestion.py's fake
provider pattern to exercise the full write -> read path against
PostgreSQL."""
