Compare locally.
Score individually.

Fix commits supply the comparison. Reference data anchor the classification task. Both update one shared model.

    1forward pass per model and function

Patched and unchanged functions provide weak supervision, not independently verified benign labels. External groups contribute to ranking only; the classification term uses the reference pool.
