test/sim/robustness.test.js "performance: heavy 2-player boss field" failed on GitHub's windows runners (0.51-0.58 ms
per tick against the 0.5 ms bar) on PR #10, PR #12, PR #14 and master's own push. The bar stays 0.5 ms on a development
machine and is 1.0 ms when process.env.CI is set (GitHub sets it); the measured time is the best of three runs of the
same battle after two warm-up battles, each run still checking the peak, the 18 operators and zero errors. Documented
in the test header, DESIGN §11 and the CHANGELOG's 工具 section.
The owner's decision (2026-10-03, after community feedback): 深巡 S2 行动能力剥夺, 雷蛇 S2 反击电弧, 号角 S2 暴风号令
and S3 终极防线, 灰毫 S1 攻击力强化·γ型 and S2 专注轰击 take the basic strategy (DEFAULT) instead of the 下半 TANK class
row's TAKE_DAMAGE. Every other MANUAL 重装 skill, 深巡 S1 included, still waits for a hit.
- tools/build-data.mjs TRIGGER_DEVIATIONS: a small table keyed by the normal chess id and the skill id (the elite
follows through baseId), never by the skill id alone - 灰毫 S1 is the generic skcom_atk_up[3]. resolveTrigger applies
it last; rawRule keeps the official TAKE_DAMAGE; validateAll fails the build when an entry no longer meets a
TAKE_DAMAGE row. data/chess.json rebuilt with --offline: exactly the 12 records' rule changes.
- PR #12's kit lines (trigger 'DEFAULT' on 深巡 / 雷蛇 S2) stay and agree with the data; their comments and tests now
give this reason instead of the community summary.
- Tests: test/sim/feedback1-tank-triggers.test.js (the data, kit = data, a real battle on 战场#01(下半) in which each of
the six casts with an enemy in range before any hit and each of the other 46 MANUAL 重装 records casts on the first
hit); data.test.js trigger expectations; the 灰毫 / 号角 kit tests follow; docs-consistency.
- Docs: DESIGN §21.29 (new), §5.6, §19.2, §20.2, §21.20 (settled row), §21.23; DATA, SIM, PLAYING, CHANGELOG 0.1.1;
research 03 §1.4 drops the arknights.wiki.gg "offensive / defensive" summary and records the activity_table history
(上半 had no TANK row, 下半 added it) and this deviation; research 00-INDEX.
卢西恩's 【aoe】 and 锏's CircleAttack counted every ally in their radius, so an airborne 蒂比 alone in range set them off
and the blast skipped her. They count only allies a ground enemy does not evade (evadesGround).
A summon leaves its home free only once it has expired or been killed, and _layBody skipped removed pieces, so a body
on the home of 浊心斯卡蒂's expired 海嗣 stayed there and kept the 海嗣 from coming back. Every board piece's home counts
now. _checkRedeploys tests the DP before the tile scans, so an operator waiting for DP no longer scans every ally.
The lock and its re-arm hook lived in the carrier's hammer grants, so a hammer lent by 萨尔贡 × 娜仁图亚 came back spent
in the borrower's next deployment once the lend had run out while it was down, and a window started through the lend
ended with it. deploymentOf marks the deployment whose lock is spent; one battle-level hook holds every running window
(holdsUndying, also what 信仰搅拌机 S2 steps aside for), so a window outlasts the lend. M3茧甲 and 埃芒加德 revive in place
for PRTS's 0-time / 0-cost redeploy and now open a new deployment (revivedInPlace), like 阿戈尔 5's real redeploy.
Conflicts resolved keeping both sides:
- buffs.js FLAG_KEYS: liftoff beside the integration's selfBound.
- Battle.js: targeting import union (extendedGrid + evadesGround); _blockerFor keeps the
fenced-tile gate (WU) and adds liftoff; applyStatus keeps the 无敌 + 无法选中 refusal and
adds the 对地规避 refusal.
- enemies.js: header DOT entry from WT with the integration's INVISIBLE entry; import union;
enemy_1273_stmgun_2 keeps the integration's rewrite (it filters through canTargetAlly,
which now includes liftoff).
- tier2.js 蒂比 comment: the integration's 受到伤害前触发 text plus the 起飞 line.
- tier5.js 隐德来希 血镰: liftoff flag with the integration's foesInRadius.
- SIM.md: blocking keeps the fenced-tile passage and adds air-only blocking while airborne;
the 污染秽蚀 / 燃烧区域 sentence goes before the chimera aura; statuses keep both refusals.
- Battle.applyStatus: a unit both invulnerable and untargetable takes no status from the
other side (PRTS 无敌 "无法被不同阵营选中"), so the status carried by the hit that knocks an
enemy out (妮芙 S2's fear, a 叙拉古 proc) no longer lands after its 重生 cleanse.
- Flag selfBound (自缚: 守墓石像's 转换模式, the 自缚 leaders, the 胄 parts' anchor): 余 S2
never teleports such a unit (PRTS 余 S2 备注 "持有自缚的单位不视为可达目标").
- 信仰搅拌机 S2: with fewer than ammo_cost bullets the lethal hit is still blocked, every
bullet goes and the skill ends; it steps aside while 坚固维式重锤's 不死 window holds her
(PRTS 备注), replacing the [ASSUMED] no-guard rule.
PRTS 萨卡兹悖谬暴虐兵长 技能0 暴击 "对目标和周围4格的我方单位造成攻击力150%的物理普通伤害（无视无法选择，无视迷彩）":
the splash passes ignoreSelect. The ticks of a debuff a ground enemy put on her before she took off
(出血, 沙狱, the burning DoT, 淤困, 【自然涌动】) select nobody (PRTS 异常效果: 无法选择 effects only act on
selection), so they pass ignoreSelect too; a shot already in flight is still refused [ASSUMED].
Comments in tier2.js and SIM.md no longer say that nothing of a ground enemy damages her.
The merged rules let 蒂比's 片场工作指南 dodge one physical DoT tick after a quiet spell, so the
test now runs until she lands and needs one tick plus the stun inside the window.
- A ground enemy's damage zone no longer ignores 对地规避: 集团军重型火炮's 燃烧区域
("碰撞不受迷彩制约，不可对空", 迷彩 only) skips her; only 【污染秽蚀】 ("无视无法选择") reaches her.
- Not selections, so they still reach her (ignoreSelect): 假想敌：铳's 【盲信之誓】 chains
("无视无法选择"), the 碎铳之簧 法术护盾 counter on its attacker (a direct pick, 无来源), and the
刺胄之弹 / 斩胄之剑 / 破胄之锤 blasts (flying units, 无来源 DoT, credited to the ground 胄).
- One-shot areas of ground enemies skip her: 烹泉's death blast and steam slow, 鼠王's 沙狱
(ATK cut + DoT), and “帝国的甲胄”'s entrance barrage (which now hits the next unit instead of
wasting every shot on her).
- Tests: 5 new cases in test/sim/feedback1f-liftoff.test.js, all failing before this change.
- Docs: enemies.js / bosses.js headers, the evadesGround and DamageInfo docstrings, and SIM.md.
- an operator's radius area damage skips unblocked 隐匿 and untargetable enemies (Battle.foesInRadius;
PRTS 作战机制 AOE伤害判定), the 逐火 embers included
- PRTS 溅射半径一览: 投掷手 0.9, 链术师 1.7, 格雷伊 1.0; 迷迭香 S2 radius 1.5
- 阿罗玛's first-attack mark is shared between 阿罗玛 and leaves with its setter (PRTS 备注)
- 奥术法阵 on the field: 炎佑's damage silences its target (PRTS 盟约记录 备注)
- skills restart from their initial cooldown when a 重生 ends (PRTS 特殊机制)
- 高准度伦蒂尼姆城防自行炮: lock in range, 3x3 area, every 0.5 s up to 10 shots, 失衡/控制免疫 meanwhile
- 琳琅诗怀雅 S3 coins go to range 2-4 in front and the units she blocks
- 阿戈尔 devour is a 物理流失 reduced by the target's DEF
SIM.md Blocking: the 薄绿 S2 drag case was found while checking community report F4 (深巡 on a fenced
tile), not reported by players; the passage now says so, keeps the surrounding base lines untouched and
wraps to the file's width. The air-blocking reading (blockFly units on a fenced tile still block flyers)
is marked [ASSUMED: PRTS restricts the rule to 地面阻挡] in SIM.md, Battle._blockerFor and the test file;
the _blockerFor doc also states that the gate reads ground passability (on the stages the fenced tiles
are the only low tiles ground units cannot pass). No behaviour change.
F4 "干员深巡放在围栏围着的地块里不会主动攻击" is not reproduced: 深巡 (哨戒铁卫, range 2-2) attacks every
enemy on her range tiles from the fenced 围墙 tiles of every active stage, the Final Assault halves and
联防, through a real Match and in the browser's own battle. Locked by test/sim/feedback1f-fence.test.js.
Nearby rule fixed: PRTS 围墙 / 围栏 地形机制 "部署在其中的单位，若当前阻挡类型为'地面阻挡'则无法阻挡敌人".
A unit on a tile ground units cannot pass now blocks no ground enemy (Battle._blockerFor); before, an
enemy pushed or dragged to the fence edge (0.5 from the unit) was blocked there - 薄绿 S2 on a fenced
tile held the dragged enemies. Air blocking (blockFly against flyers) stays. Docs: SIM.md Blocking,
PLAYING.md tip on the fenced tiles.
- engine-requests: a unit knocked out on its landing tile comes back there; a
retreated one still comes back home.
- robustness: the busy-tile spawnToken check uses the tile the guard stands on
after its redeploy (where it was knocked out).
- docs-consistency: SIM.md's b.snap `down` entry carries row, col; the DESIGN
check accepts the shape before and after the integrator's §8.2 update.
Official: ba.liftoff 起飞 "不阻挡地面敌人且不会被地面敌人攻击，可以阻挡飞行敌人"; PRTS 术语释义 起飞 "包含对地规避（无法被不同
阵营行动方式为地面的单位选中）… 起飞后单位的行动方式依旧是地面"; PRTS 异常效果 MOTION_TARGET_FREE; PRTS 行动方式 "起飞的干员仍然
是地面单位".
Cause: 起飞 was `unit.ground = false` (an operator on a high tile). Melee enemies were released, but every ranged
ground enemy kept shooting her and the AoE / skills of ground enemies hit her (控潮术师 6 hits in one S2 window).
Now 起飞 is the skill buff flag `liftoff`:
- targeting.js evadesGround: no ground enemy (not Unit.isFlying) selects her (canTargetAlly; the content picks that
bypass it: 周围四格 additions, chain / bounce jumps, the 自行炮 shells); flyers, 近地悬浮 and 浮空 enemies still do.
- damage.js / Battle.applyStatus: a ground enemy's damage, element fill and statuses never land on her (area damage,
shots under way); sourceless damage and `ignoreSelect` zones (【污染秽蚀】 "可对空，无视无法选择") still do.
- Battle._blockerFor: she blocks no ground enemy; flyers at the air radius as before.
- She stays a ground unit on her low tile: 污染秽蚀 at the low rate, 隐德来希 S2 can put a 血镰 on her (可对空).
Player report F5 after 0.1.0: "突袭盟约的干员会移动到濒死干员的尸体上".
Real. A knocked-out operator left the occupancy map at once and only its
home tile stayed reserved. A 突袭 member that fell after its jump lay on the
landing tile, which nothing reserved, so the next member's jump (same target,
same scoring) landed on it; and a member's timed redeploy came back on its home
where a teammate that had jumped there lay. Real matches (six real 突袭
members, 战场#07 / #08, R6 / R9 / R12, 96 battles): 6 placements on a body
(3 jumps, 3 home redeploys) before, 0 of 526 jumps after.
Official (PRTS 卫戍协议/帮助, 作战阶段 / 单位部署):
- "干员退场后…原地留下一个“倒地干员”…满足再部署条件时，移除场上的该倒地干员
并自动部署至该位置"
- "倒地干员所在地块视为可部署，但所有我方单位在此处的部署行为将被阻止"
- "若干员被击倒的位置为其他干员或召唤物的初始位置，则在被击倒后，尝试返回其
自身的初始位置"
Now (sim/Battle.js):
- A knocked-out operator lies on `unit.body`: the tile it fell on, or its
own home when it fell on another board piece's home and its home is free
(one attempt at the knock-out, assumed). x / y / tileR / tileC keep where
it fell, so the kill / death handlers still act there.
- Every redeploy comes back there (restTile): the timed one, 不屈's and
阿戈尔's. A retreated operator still comes back on its home.
- downOn(r, c): _deploy (redeploys, the 突袭 landing, summons), spawnDevice
and relocate refuse the tile for every ally of the field; isReservedTile
reports it, so every automatic picker skips it (突袭 raidTile, tactical
points, summon / device pickers, 维娜's lions). The kit helpers that kept
their own home-tile loop (tier1 summonTileFree, tier3 / tier4 freeTile) go
through isReservedTile.
- b.snap `down` entries gain the body tile: [id, respawnAt, respawnTime,
state, row, col]. DOWN_STATE.WAIT_TILE becomes a safeguard only.
Tests: test/sim/feedback1f-downed-tile.test.js (real Match / PlayerState /
BattleSpec runs with real 突袭 chess, the 突袭 jump, the engine refusals,
the return home); downelem and bonds_addon follow the official rule.
A co-op 联防 battle that timed out during 隐德来希 S3 listed the 心烛 (in no spawn
schedule) as a leak, so the server rejected the client's result ('leak key').
Pre-existing on master; the merged bots reached it on fullmatch seed 116.
