 - 自制投石机「索敌不受阻挡影响」：被站在排气格栅上（隐匿）的干员阻挡、范围内又没有别的干员时不会攻击，和原版一样；其他敌人仍会攻击阻挡自己的隐匿干员（社区反馈）。
 - 升级调度中心后，新增的商品栏位立即放上新卡，不用等下一次刷新（社区反馈；官方教程「升级后将出现更多的商品栏位」）。
 - 被冻结或晕眩的敌人仍会被接触到的干员阻挡：干员再部署到它身边、或阻挡数空出来时会立即挡住它，隐匿的敌人也随之破隐，不用再等冻结或晕眩结束；沉睡、浮空、恐惧和不可阻挡的敌人仍然不会被阻挡（GitHub #232，感谢 @ccyl、@kukiC）。
+- 蕾缪安三技能锁定时攻击范围里没有敌人，技能不会再自动结束：剩余子弹和已有的锁定都保留，下一个敌人进入范围就立即继续锁定，子弹打完才结束并开始轰炸，等待期间锁定标记一直显示（社区反馈；弹药类技能打完才结束，PRTS 卫戍协议帮助「通常不会自动关闭技能」）。

+#### 25.22.8 Community report 「蕾缪安3技能范围里没人好像会自动结束」 (relayed by the owner): 蕾缪安's S3 waits with its bullets while nothing is in her range — `kits/ops/chess_char_6_01-lemuen.js`, `render/fx/locks.js`
+
+- **Seen** (a script on the parent 0255afd: S3 cast with 5 bullets, the locked enemy killed by someone else after 2
+  locks, another enemy alive outside her range): the skill ended at the next lock tick
+  (1.00 s, `skillEnd` reason `ammo`), 3 bullets thrown away, 2 shells; an enemy that came into her range 3 s later found
+  it over. A locked walker leaving her range ended it the same way (4 locks, 1 bullet thrown away). In golden the elite
+  蕾缪安 of roster-018 ended three of her five casts early (2 / 6, 5 / 9 and 6 / 9 bullets left).
+- **Official**: the skill text 「每0.5秒消耗1发子弹依次锁定敌人……攻击装有5发弹药，打完后结束（可随时停止技能）」: an ammo
+  skill ends when its bullets are spent or when the player stops it. PRTS 卫戍协议/帮助 §作战阶段 技能操作: 「可执行的技能
+  操作包括开启/关闭技能，通常不会自动关闭技能」 — the only automatic close is 玛露希尔's 召唤使魔; 蕾缪安's S3 is on the
+  basic strategy. The client (charpack char_4193_lemuen, battle/buff_template_data.json): the S3 mode's lock is an attack
+  that needs a target (`_minTargetNum` 1, `_allowNoTarget` 0, cooldown `aim_interval`); the skill buff `lemuen_s_3`
+  switches to the S3_End mode (the bombardment) on `ON_BUFF_FINISH` only, and nothing ends it for want of a target. PRTS
+  S3 note: a mark follows its target and stays where the target left.
+- **Cause**: the kit's lock tick ended the skill when `pickLock` found nobody and anyone had been locked —
+  `if (!e) { if (m.lemLocks.length) skill.end('ammo'); return; }` (chess_char_6_01-lemuen.js:169 on the parent), there
+  since the initial import with no decision behind it.
+- **Now**: with nothing to lock the skill waits, bullets and locks kept — the marks follow their enemies (out of her range
+  too) or stay where they left — with its lock ready: the next enemy that comes into her range (or is 通缉) is locked on
+  the next tick, then every `aim_interval` s. The skill ends when the bullets are spent and the shells fall on every mark
+  in lock order, as before. While it waits she gains no SP (a running ammo skill holds it, as before); knocked out or
+  withdrawn, no bombardment (unchanged); a battle that ends meanwhile ends without shells (nothing left to hit). The S3
+  `lock` fx carry `hold`: render/fx/locks.js keeps such a reticle while the shooter's view has the skill bit (UF.SKILL)
+  and counts its LOCK_T (5 game s) from the skill's end — without it the reticles faded 5 s into a wait. S2's aim lock
+  (no `hold`) keeps its timeout.
+- Unchanged and noted: the client lock's 0.1 s pre-delay is not modelled (the lock lands on its tick, as before).
+- Seen on the way, not changed (S2, not this report): 归乡邀约 spends a bullet on every normal attack (5 of its 6 gone in
+  8 s of attacks on an enemy that is not 通缉), while PRTS's S2 note says only the aimed snipe at a 通缉 target spends one
+  (「若目标为被通缉状态，则攻击改为消耗1发弹药的瞄准狙击，否则不消耗弹药」) — left to the owner: fixed, S2 would hold its
+  buff until 通缉 enemies come, a large change.
+- Golden: 3 scenarios — traced on both trees with an instrumented copy (SkillRuntime start / end logged, the round's
+  fields and the carried SP); in each the first divergence is an S3 the parent ended with bullets left and nothing in her
+  range:
+  - roster-018: the elite 蕾缪安's first S3 (7.63 s) ended at 9.63 s with 2 of 6 bullets left; now the 6th goes at
+    12.00 s (first differing snapshot window 0–10 s).
+  - boss-boss_3-pair: her second S3 (27.8 s) ended at 30.3 s with 4 of 9 left; now all 9 by 34.43 s (window 30–40 s); the
+    boss now falls at 199.53 s (before: `forced` at the 200 s cap with 145080 HP left).
+  - coop2-NORMAL-14-standins: ai_0's 蕾缪安 (her own kit) — in round 11's battle her S3 ended at 17.2 s (6 of 8 left) and
+    77.97 s (7 of 9); now all bullets are spent and the third cast does not come, so she enters the round's 联防 with
+    25.96 SP instead of 10.27, casts S3 there and kills one more of h_0's leaked enemies: h_0 loses 1 LP less (rounds
+    11–12 LP 18 → 19, 8 → 9; lpLost 30 → 29; ai_0 kills +1, dmgDealt +288).
+  - bonds, standins and diy unchanged.
+- Tests: `test/sim/feedback5-lemuen-s3-wait.test.js` (3: the killed target and the walker who leaves fail on the parent —
+  the skill ended —; the battle that ends while she waits passes on both), `test/render/fxproj.test.js` +1 (a held lock
+  stays while the shooter's skill bit is on, then LOCK_T after; an unheld one times out — fails on the parent's
+  renderer); `test/content/kits_t6.test.js`, `kits_alt_t6.test.js`, `test/sim/feedback3-ammo-bar.test.js` pass unchanged.

+// ends when its bullets are spent ("攻击装有5发弹药，打完后结束（可随时停止技能）"); in the client data her S3 lock needs a
+// target and only the spent bullets end the skill buff (lemuen_s_3 → the S3_End bombardment mode); the 卫戍协议
+// automation never stops a skill (PRTS 卫戍协议/帮助 技能操作: "通常不会自动关闭技能"). Now the skill waits — bullets and
+// locks kept, the marks following their enemies — and locks the next enemy that comes into her range at once.
