…ablish relationship with Thing - add thing_id FK + relationship on NMA_WeatherData with validation - cache Thing.nma_pk_location and resolve thing_id in WeatherData transfer - skip unlinked WeatherData rows to prevent orphaned children - add alembic migration to backfill thing_id and enforce NOT NULL - update WeatherData legacy tests to include Thing linkage
