"""Integration test for the multimodal task system (free, local, no model).

Runs each modality's verifier on a known-GOOD and known-BAD example to prove the
objective reward signal works, plus the blended-reward routing. The full model-in-the-loop
integration is the smoke run on HF; this proves the verifier plumbing first.
