// test/sim/feedback5-cb3-pins.test.js — community reports of 2026-10-06 that this tree already answers (stream CB3; they pass
// on the parent commit — nothing changed for them), pinned:
//   item 2 「敌人在干员铃兰技能范围内没有开技能，在攻击范围才开」 — 铃兰's default S3 狐火渺然 ("攻击范围扩大") was on the basic
//     strategy up to 0.1.4 (DEFAULT: an enemy in her own 2-tile range); 0.2.0's ACTIVE_RANGE (the owner's rule of 2026-10-05,
//     tools/build-data.mjs resolveTrigger) casts it with an enemy inside its running range y-8 (3 tiles ahead).
//   item 16.1 「突袭转职玛恩纳…攻击范围里有怪的时候即使长时间没攻击也不会突袭」 — the bond text itself: "干员10秒内未进行攻击或技能
//     就绪时，若范围内没有敌人，则…再部署": a 解放者 never attacks with his skill off, so his 10 s are always met, and an enemy in
//     his range is the one thing that holds the jump — as for every member.
//   item 16.4 「归鲨被吃的时候不是变替身而是进了再部署」 — an 阿戈尔 devour mark on 归溟幽灵鲨 switches her to her 替身 (normal, 联防,
//     boss fields); never a knock-out (a sweep of 400 random chains on this tree and v0.1.2–v0.1.4: 0).
//   item 46 「荒芜拉普兰德开技能之后好像没有普攻了…叙拉古恐惧概率不高」 — during her default S3 every drone is out chasing (PRTS
//     技能流程), so she makes no attack of her own; her attacks come back when it ends. 叙拉古 6's proc is PRTS's pseudo-random
//     rule: 0.139 % per 普通伤害 attempt, +0.139 % per miss, shared by the player's members (3 % on average).
