PR #347 by @CXUtk, applied with changes. Kept: 追逐模式 lasts the gain's whole 5 s — PRTS 假想敌：铳 末日布道 "令全场的
“碎铳之簧”获得5秒增益…增益期间切换为追逐模式", “碎铳之簧” 追逐模式 "持续追踪令其进入该形态的场上的假想敌：铳移动" (no
arrival clause, unlike the 铳's own 冲锋模式, which ends "到达目标所在位置后"); data skill 2: cooldown 45, initCooldown 20,
dog_duration 5, move_speed 8. kitSpring no longer ends the chase when it reaches the gun or comes within 1 tile; with no
gun left on the field the spring holds still until the gain ends (until 0.2.1 that ended the chase at once).
Not taken (the maintainer's decision on the Grok triage): the second gun's half-cooldown first-call delay and the cond
that refused a call while any spring was chasing — neither is in the data, and the lock contradicts the handbook's
「持续召唤场上所有“碎铳之簧”向自身移动」 (a call takes every spring to its caster). Both guns keep their data timers, so on a
pair field the mirrored gun's call, a tick after the first, retargets the springs for a new 5 s.
Measured (notes repro-347.mjs): a spring 0.2 tile from the gun chased 0.03 s, one 5 tiles away 2.97 s; now 5.03 s both.
Tests: test/content/hidden-gun-pursuit.test.js (new, 5; the arena harness and two tests are the PR's): the full 5 s
next to a moving gun and with no gun left fail on the parent; the pair timing (20 s after each gun's spawn, then every
45 s, the two calls a tick apart), a mid-chase call retargeting the springs for a new 5 s and the solo timing guard
against the stagger / lock. test/sim/feedback1e-healers.test.js E2 audit: the fields whose leaders / parts a healer must
block run 200 s instead of 120 — on the solo 铳 field the springs now first meet a healer at 145 s (at 21 s until now).
Golden (on top of the portal commit):
- fields hidden-boss_9-pair: the springs spend 5 s invulnerable per call, so they take less (actrpa 855522 → 722451,
actrpb 798033 → 660498, actrpc 1384683 → 1168947) and pass less on; leader left 3511007 → 3747749; p2's deaths
7 → 12 (longer tramples); still 8 / 8 kills, no leak.
- fields hidden-boss_9-solo: leader left 1932856 → 2011732; the springs take less; 隐德来希's candles (5601_entlec, an
enemy-side summon) 6 → 8.
- matches coop2-ABYSS-10-boosted (hidden boss_9): still cleared at 800 LP; the seats' leader damage shifts
(7523075 / 6369365 → 6992346 / 6900614).
Review follow-up for E2 (not reproduced, no behaviour change):
- blockRun fills the skill's SP (and puts the patient back to 5 %) the
first tick the healer blocks, and tests 2 and 3 assert the skill is
cast or running while it blocks: all 56 healer loadouts now cast in
the window (half never did at the default initial SP).
- The reported 炎 boss round makes 录武官's skill ready when she first
holds 卢西恩 / 不祥幻影 and asserts it is cast or running then.
- The boss test says what it covers: 0 healer damage on all 20 boss /
hidden fields; healers block 卢西恩 / 不祥幻影 (h07_05) and a
patrolling 碎铳之簧 once its shield is broken (h08_02); the other
leaders and parts cannot be blocked by a block-1 unit.
- SIM.md: the healer qualifier follows the "one-line flip" sentence, so
"This replaces..." refers to the every-blocker rule again.
- ai.js header, Battle.blockedTargets and targeting.js: the blocked-first
rule is for attacks that hit enemies; a heal attack keeps selecting
injured allies (PRTS 卫戍协议/帮助).
- PLAYING.md: the healer exception names 咒愈师 as the one that hits.
A community report said a medic blocking a roaming boss in a 炎 build stops
healing and strikes the boss, its 强力击-type skill included. The real sim
does not do that: every pure healer (医师 / 群愈师 / 疗养师 / 链愈师 / 行医,
the map characters, normal and elite, every skill) blocking an enemy keeps
healing and never targets it, under every bond as a member, with every
equipment item and on every boss / hidden field (卢西恩 and its phantom,
the 剑 / 锤). Official: PRTS 卫戍协议/帮助 "对于医疗干员（咒愈师分支除外），
攻击目标为需要治疗的单位". The only damage a pure healer deals is a bond's
own effect by its text (卡西米尔's pulse while blocking).
No behaviour change: the rule is spelled out in SIM.md and ai.js
acquireTargets, and test/sim/feedback1e-healers.test.js locks it (the
reported 炎 boss round, every healer x bond, items, heal-mode skills of
古米 / 塞雷娅 / 波登可, 咒愈师 and 吟游者, every boss template).
