"""
Shared refusal heuristic for the causal-patching benchmark.

Both extract_and_train.py (label generation for probe training) and
run_patching.py (behavioral measurement at test time) must apply the
IDENTICAL heuristic — otherwise train/eval labels are inconsistent
and the causal claim is confounded by label drift.
