+绝境 leaks per alive bot in R12 / R13: solo 8.0 / 9.2 → 5.7 / 4.8, co-op 20.5 / 20.7 → 18.5 / 15.8. Co-op bounty leaks
+are bound by the drafts, not the pick: in 223 of the 312 co-op 绝境 bounty picks no card still on offer had a kill
+chance ≥ 0.5 (solo 22 of 80), and only 5 picks (solo 0) took a card below 0.5 while one ≥ 0.5 was on offer — re-measure
+after the bounty-half fix (player report #2). Strategies played alone (solo 绝境, seeds 201–220, forced with `--band`):
+坎诺特 9 → 14 wins of 20, 昆图斯 9 → 11, 杜宾 8 → 9 (keeping an unused 教鞭 vs dropping it: 11 vs 11 wins over 24 杜宾
+matches — kept, as it costs nothing but a hand slot). Decision time per bot prep is unchanged (one thread, back to back
+on a quiet host, seeds 1–6, solo 绝境 / co-op 绝境; the rehearsal included): wall clock p50 / p95 94 / 191 → 89 / 205 ms
+and 86 / 175 → 83 / 162 ms, CPU 131 / 314 → 124 / 329 ms and 97 / 209 → 91 / 188 ms; the heuristics alone (CPU) 31 / 74

+refreshes); a 机变 pick 0.07 → 0.15 ms (p50). Over the 40-seed A/B the summed prep CPU per match moved −6 % … +2 %. The
