v5.0 Empirical Round 2
Round 2 (dataset version 1.1, corrected), on 243 in-scope events (Feishu group after the round-1 cutoff, with the bot’s replies present, and the operator’s Claude Code sessions): f_v5 matched the wanted mode 25/243 exactly (0.1029, Wilson 95 % 0.0707 to 0.1475), 54/243 with M1 and M2 read as one (0.2222), 101/243 across the five classes (0.4156, 0.3555 to 0.4784); the bot itself matched 34/70 of the corrections where its mode could be read; on the 173 controls the operator let stand, f_v5 would have changed 108 across the five classes. Label reliability: on the operator’s own answers the models’ consensus matched 6 of 9 exactly (Wilson 95 % 0.3542 to 0.8794), 8 of 9 with M1 and M2 as one, 8 of 9 across the five classes; with the delegated answers included, 16 of 21 exactly, 20 of 21 with M1 and M2 as one, 20 of 21 across the five classes. Truth is the operator’s own answer on 9 in-scope events, a delegated answer on 12, the models’ merged label on the rest. Result case A. The canon is unchanged.
