feedback5: merge CB2 — community reports (healers / summons): 刺玫's S2 heals the most injured ally again (the counter's heal alone goes to her protégé), 琳琅诗怀雅 heals herself and her 破财消灾 cost restarts at 5 DP with every deployment, 赫默's S2 casts at full SP so the drone takes the field at once, the countdown summons (医疗探机, 诅咒娃娃, 海嗣 and four 自选 ones) take no damage, are never healed and show the life left on their bar, stacked ground areas stay readable; §25.16 after CB5's §25.19 (renumbered with the later merges); golden: vs feedback5 CB2's own rules — roster-001/002/003/005/008/016/018/027/035/037/045/046/049, bond-deputShip-low/high, bond-suntShip-high, bond-victoriaShip-low/high, bond-visiShip-low/high, boss-boss_1/3/5/7-pair, hidden-boss_9-pair, unite-1, matches solo-FUNNY-2, coop2-HARD-4, coop3-ABYSS-5, coop4-ABYSS-7, coop2-NORMAL-8-serverrun, coop2-ABYSS-10-boosted, coop2-NORMAL-14-standins; vs CB2 exactly CB5's 18 bot matches

Merge fixes (the three tests the trial merge failed):
- test/content/summon_loadout_conflicts.test.js (赫默's drone lifetime per module variant): it asserted "no cast yet"
  after the drone's redeploy time and then cast S2 by hand — with nobody hurt the old DEFAULT rule never cast. S2 now
  casts by itself the tick its SP is full (22 s), which is the official rule (client skill skchr_silent_2: no
  `_trigger`, `_allowNoTarget` 1, `_checkHasTargetBeforeDoCast` 0; CB2 64f8bf9), so the test waits for that cast and
  checks both drones' lifetimes from it. Failed on fb5-cb2 itself (the stream did not run the file).
- test/sim/feedback1f-downed-tile.test.js (F5 rule 3): its "killed" case killed 浊心斯卡蒂's 海嗣 with 1e9 true damage;
  the 海嗣 is a countdown summon now — 无敌 + 禁疗, the official state (PRTS 海嗣 备注 「持有禁疗、无敌」) — so it only
  expires. The killed case takes 缪尔赛思's 流形 (a placed board summon that is attacked and killed and also comes back on
  its tile 25 s later); both cases now also check the summon's return. Failed on fb5-cb2 itself.
- test/golden-standins.test.js (the 补位 match fields at least 3 different stand-ins): already failing on feedback5
  37558f0 — CB5's 调度中心 upgrade card changed the human seat's shop in coop2-NORMAL-14-standins, which then fielded
  only 2 of its 7 not-owned chess (忍冬 → Sharp, 安洁莉娜 → Raidian). tools/golden.mjs MATCH_NOT_OWNED adds 缄默德克萨斯
  and 铃兰 (chess its AI fields now): 4 stand-ins (Sharp from round 4, Misery from 7, 预备干员-辅助 from 9, Raidian in 12);
  the test is unchanged, test/golden/README.md says 9 chess. This moves coop2-NORMAL-14-standins only.
- docs/history/0.2.0.md: the §25 intro's two stream lines joined into one sentence (the merge had cut it).

Golden moves outside CB2's commit list are CB2's rules on the paths CB5 gave the bots: coop2-HARD-4 fields 琳琅诗怀雅
from round 6, coop2-NORMAL-8-serverrun 刺玫 from round 7, coop2-ABYSS-10-boosted 刺玫 from round 2,
coop2-NORMAL-14-standins 刺玫 from round 3 and 琳琅诗怀雅 in rounds 6-7 (instrumented); coop2-NORMAL-3 and coop4-FUNNY-6
(in CB2's list) still field 刺玫 and her S2 heals now reach other allies (36 / 205 heals), but no kill, leak, LP or
end stat changes, so their digests stay.

+
+#### 25.16.1 「刺玫开技能（装备源石药剂）之后不能治疗」 (item 12): only the S2 counter's trait heal goes to her protégé — `kits/ops/chess_char_1_06-vendla.js`
+
+- **Seen**: during 荆藤庇荫 every trait heal went to the protégé, usually at full HP — a 源石溶剂 carrier drained from 1017 to
+  297 HP over the skill with all eight heals spent on a 9000 / 9000 ally.
+- **Official**: 「该角色受到攻击时刺玫对目标造成攻击力20%的法术伤害并仅对该角色触发刺玫特性」 (en "…and activates her Trait on the
+  ally"); the client buff `vendla_tr` heals through the selector S2TraitHealRange (the `vendla_s_2` holder) only for a
+  damage whose modifier carries the key `vendla_s_2` — the counter, `vendla_s_2[extra_damage]` — else through
+  TraitHealRange (`_excludeOwner` 0, 禁疗 excluded).
+- **Now**: the counter's damage names the protégé (`traitAlly`); every other damage she deals heals the lowest-HP ally of
+  her range, herself included, skill running or not.
+- Golden: roster-001 / 002, bond-deputShip-low / -high, bond-suntShip-high, bond-victoriaShip-low / -high, the bot matches
+  solo-FUNNY-2, coop2-NORMAL-3, coop3-ABYSS-5, coop4-FUNNY-6, coop4-ABYSS-7. Tests:
+  `test/content/feedback5-vendla-heal.test.js`.
+
+#### 25.16.2 「琳琅诗怀雅不会治疗自己」 (item 18): S1 仗义疏财 heals her own tile too — `kits/ops/chess_char_3_04-swire2.js`
+
+- **Official**: the client charpack (char_1033_swire2, mode S1, ability HealAlly) selects with range x-4 — the 3×3 with her
+  own tile —, ally side, `_excludeOwner` 0, max HP ratio 0.7, one target. **Cause**: the kit skipped her and kept
+  Chebyshev distance 1 only. **Now**: the lowest HP ratio below 70 % of the 3×3, herself included (her own 禁疗 still
+  stops it); the owner's cadence of 2026-10-04 is unchanged.
+- Golden: roster-027. Tests: `test/content/feedback5-swire2-self-heal.test.js`.
+
+#### 25.16.3 「进入联防阶段琳琅诗怀雅所需的复活费用应该重置，正常对局中死亡之后再部署复活费用也应该重置」 (item 33): 破财消灾 restarts at 5 DP with every deployment — `kits/ops/chess_char_3_04-swire2.js`
+
+- **Official**: PRTS 破财消灾 备注 「再部署时重置本天赋费用消耗」; the client buff `swire2_t_2` doubles the `cost` of its own
+  blackboard, rebuilt when she is deployed. **Cause**: the kit kept its save count for the whole battle (5 → 10 → 20 across
+  a redeploy). **Now**: reset at each of her deployments (battle start, redeploy, 突袭 再部署); a 联防 field is a battle of
+  its own, so it always started at 5 (pinned).
+- Golden: roster-008 (a cheaper save after a redeploy), roster-049 (snapshots only). Tests:
+  `test/content/feedback5-swire2-revive-cost.test.js`.
+
+#### 25.16.4 「赫默的无人机在2技能好了之后应该秒放」 (item 34): S2 医疗无人机 casts at full SP — `kits/ops/chess_char_2_02-silent.js`
+
+- **Seen**: S2 full at 26 s and no cast while nobody was hurt; the drone came only once an ally in her range was injured.
+- **Official**: the client skill `skchr_silent_2` (AUTO) has no `_trigger`, `_allowNoTarget` 1, `_checkHasTargetBeforeDoCast`
+  0 and a RechargeToken action — no cast condition; `_stopSpWhenTokenIsFull` 1 = PRTS S2 备注 「库存达到上限后赫默获得阻回，
+  直到库存被消耗为止」.

+- Golden: roster-003 / 005, bond-visiShip-low / -high. Tests: `test/content/feedback5-silent-drone.test.js`.
+
+#### 25.16.5 「赫默的无人机、浊心斯卡蒂的海嗣等这种召唤物不会受到外来伤害（包括源石地板），也不会被干员治疗，血量随时间减少」 (item 26): the countdown summons — `content/tokens.js COUNTDOWN_SUMMONS / startCountdown`, `sim/snapshot.js unitTuple`, `sim/units.js` (`countdown`), the kits of 浊心斯卡蒂, 温蒂, 莱伊, 鸿雪, 酒神
+
+- **Seen**: a 海嗣 on 活性源石 lost 70 of its 100 HP every second; a hurt drone drew every medic's heals and the 吟游者
+  regeneration; their bars were plain HP.
+- **Official / sources**: PRTS 斯卡蒂的海嗣 备注 「持有禁疗、无敌」; the token prefabs give 海嗣 and 沙地兽 the abnormal flags 5 +
+  7, 工程蓄水炮 7; their lives are suicide buffs (`suicide_after_buff`, the drone's `skcom_withdraw`). The report describes
+  the official mode: no outside damage, no heal, a bar that runs down like a timer and the summon gone when it is empty.
+- **Now**: the summons that "不会受到攻击" and leave after a fixed time — 医疗探机 (10 s), 诅咒娃娃 (15 s), 斯卡蒂的海嗣 (25 / 30
+  s) and the 自选 工程蓄水炮 (20 s), 沙地兽 (25 s), “打字机” (25 s), 本能的召唤 (10 s) — hold 无敌 + 禁疗 from each deployment
+  (`startCountdown`, called where each lifetime is scheduled) and the snapshot's hp is maxHp × the share of the life left
+  (`unit.countdown`). The sim HP stays full, so no selector sees a low-HP summon. Summons that block and are attacked
+  (沙之碑, 战术装备, “小自在”, 结构性原理, 狼群 …) keep real HP.
+- [ASSUMED]: 无敌 + 禁疗 for the four whose base prefabs carry no flag (医疗探机, 诅咒娃娃, “打字机”, 本能的召唤), and the bar as
+  a display of the time left — from the report; no HP-drain node exists in the client data.
+- Golden: snapshot hashes only (the bar): roster-003 / 016 / 018 / 035 / 045 / 046, bond-visiShip-low / -high,
+  boss-boss_1 / 3 / 5 / 7-pair, unite-1; gameplay too: roster-005 (medics no longer heal the drone), roster-037 and
+  hidden-boss_9-pair (a 海嗣 / drone under damage stays up). Tests: `test/sim/feedback5-countdown-summons.test.js`. Docs:
+  docs/SIM.md (token pieces), docs/PLAYING.md.
+
+#### 25.16.6 「炼金师分支干员的炼金单元等范围持续性技能特效太亮（尤其是多层叠加以后）」 (item 14): stacked areas stay readable — `render/fx/zones.js zone / zoneAlpha`, `render/fx/simfx.js`, `kits/ops/chess_char_5_15-thorn2.js`
+
+- **Cause**: 引星棘刺 S2's drifting unit was re-sent every second and drawn as a new additive zone for the rest of its life —
+  up to twelve layers on one spot; overlapping units (锡人's charges, several alchemists) added up the same way.
+- **Now**: the fx carries `key` and the client moves / resizes that one zone; a persistent area (> 3 real s) is drawn at
+  0.16 / 0.5 (disc / edge) and ÷ √n among the n persistent areas overlapping it; short bursts and telegraphs unchanged.
+- Golden: unchanged. Tests: `test/render/feedback5-zone-stack.test.js` (node; no browser suite draws zones).
+
+#### 25.16.7 Answered with the evidence: items 11, 13, 31, 32 — no change
+
+- **11 「链愈师…只能从周身8格里的干员开始，最远不会跳出攻击范围，…即使后续跳跃干员满血也会按照规则顺序跳跃」**: the x-4 jump
+  around the last one healed and full-HP allies jumped in order are 0.2.0's WE1 (§25.7.6; on v0.1.4 a full-HP ally was
+  never jumped). The main target is the lowest-HP ally of the whole attack range y-2 (PRTS 分支特性信息), and the client's
+  chain selector (`projectile_chr_papyrs`: `_rangeId` x-4 around the hit, `_maxTarget` 3) has no attack-range bound, so a
+  jump may leave the range — not implemented.
+- **13 「有的持续造成伤害类的技能无伤害（如炼金师分支干员的炼金单元）」**: not reproduced — every DoT skill of the pool and of
+  the 自选 operators deals damage once its condition is met (a sweep with two layouts; on two real stages 锡人 S1 / S2 and
+  引星棘刺 S2 / S3 deal 13 000–134 000, the same on v0.1.4). The only zero is the hidden 锡人 record chess_char_1_16 (never
+  in the shop) whose kit lacks S1. The stacked, over-bright zones (item 14) are the likely cause of the impression.
+- **31 「伺夜的召唤物随时间增长的狼影最高能叠三只（即在新的狼影恢复前能受到三次致命伤害才死亡）」**: what the sim does (kit pack
+  and placed piece, this tree and v0.1.4): 2 狼影 at deployment, 3 after 25 s, lethal hits 3 → 2 → 1 at full HP, the third
+  into the 战术点形态 — PRTS 狼群 备注. Pinned by `test/content/tokens_devices.test.js`, `kits_alt_t3.test.js`.
+- **32 「吟游者的特性能恢复战术家的召唤物、不屈者分支干员的血量…（但赫默的无人机、浊心斯卡蒂的海嗣这种的血量不可以恢复）」**: the
+  trait is 生命回复速度, which 禁疗 and 无法被友方治疗 do not stop (§25.6.8): 狼群 440 → 532 and 斥罪 1480 → 1618 HP in 3 s
+  under 魔王 (pinned by `test/content/feedback5-regen.test.js`); 孤立 units stay out (PRTS 孤立). The countdown summons
+  cannot be refilled since §25.16.5.
