name: Recommender canary

# QW8: PR/deploy installs pin expert_op4grid_recommender (recommender-pin.txt).
# This weekly canary floats to the LATEST release and runs the backend suite,
# so a breaking upstream release surfaces here (a red canary = "bump the pin
# after checking") instead of turning an unrelated PR red or shipping a
# regressed image on a zero-change rebuild.
