Centralize ladder win condition in shared ladder_rules.yaml

john-b-yang · claude · john-b-yang · commit 8852260a9e7e · 2026-07-07T02:29:49.000Z
Every ladder run config duplicated the same ladder_rules block. Extract it to
configs/ablations/ladder/ladder_rules.yaml (min_round_wins: 2, win_last_k: 0)
and include it from all run configs so the win condition lives in one place.
