core/evals/teaching_injection_resistance/runner.py

"""teaching-injection-resistance lane runner.

Verifies the SPECULATIVE-only admission contract for non-identity
false-fact corrections, and the REJECTED_IDENTITY contract for
identity-adjacent attacks smuggled inside a factual frame.

Both verdicts are deterministic functions of CognitiveTurnResult.
No wrapper classifier, no post-hoc filter, no LLM judge.

Conforms to the framework interface: run_lane(cases, config=None) -> report.
