"""Agreement with the teacher on the held-out dev sets (synthetic and real).
The dev items carry the teacher's (Haiku 5.5, thinking) label as their last
message. A student is run on the same messages through Ollama, schema-forced,
thinking off, and compared field by field. This is agreement, not accuracy:
the hand-labelled testset.jsonl is the accuracy check.
