"""Domain job handlers: safety scoring and content analysis (US02-06).

Importing this module registers the ``safety_score`` and ``analysis`` job types so
the generic worker can run them per item (one item = one ``asset_id``). Each handler
delegates to its service, which owns the real work and the privacy gate. Handlers
are idempotent: re-scoring or re-analyzing one asset is safe after an interrupted
attempt.

Providers/models are the service defaults here (real NsfwModel / vision provider);
tests exercise the services directly with injected fakes rather than the worker.
