2026-07-14 (review): ADOPTED splitting the conformance reviewer into a terse binary

2026-07-14 (review): ADOPTED splitting the conformance reviewer into a terse binary verdict call and a SEPARATE explanation call. Asking for verdict+explanation+fix in one call drives GPT-4o's false-negative rate from 26.2% to 73.2% (HumanEval) and 35.9% to 87.9% (MBPP) — it does not find more bugs, it REJECTS CORRECT CODE (arXiv 2603.00539, Springer Automated Software Engineering). All five abcd agents currently do the forbidden thing. Largest measured effect size in the research and free to apply. Also adopted: fix-guided verification filter (execute the proposed fix as a counterfactual; if no test outcome changes, the rejection was hallucinated — FNR 54.8% -> 16.3%).
