- Remove variant B (Brown cap, +1 for higher beating lower) from rules, engine, bots and simulator; a higher belt beating a lower one gains 0. - Final Exam: the defender fights as a Black belt (RULES.md v0.7). Ties to the defender and best-of-3 stay as simulator switches (`--exam`). - Report stripe income per source as gains and losses. - Add ten one-sidedness measures sampled at turn ends (lead gap, winner margin and lead share, halfway leader, last lead change, contention, rank swaps, leader Kumite losses, Exam challengers, winner pace). - Plan: decisions D28-D33 and the detailed Phase 6.
