Seen: the sim moved a displaced enemy at once and it walked / swung again on the next tick; players compared with the
official game (PR #392: 「被推/拉完的敌人会先站住一小会儿再走」). Research (scratchpad report r3): PRTS 失衡位移机制 — a force > 0
puts an enemy in the UNBALANCE state machine with a 0.1 s 失衡硬直 floor, ending when its speed is ≤ 0.1 m/s, on 浮空 or a
forced state change; 异常效果图鉴/失衡免疫 「失衡期间无法自主移动、发动攻击、使用技能」; 异常效果 — not an abnormal status (水遁忍者's
check still runs); 游戏数据基础 推力-位移近似对应表 位移时间 (whole frames at 30 fps); 推与拉 拉力 「作用时间默认为 1 s；若本次受力
等级 < −1，作用时间改为 0.5 s」, 急停 keeps the state to the window's end; 特殊机制 静态刚体 (0.1 s 保底); 术语释义 浮空.
Now: constants.js PUSH_UNBALANCE {−2: 0.2, −1: 0.4, 0: 0.8, 1: 0.9, 2: 32/30, 3: 35/30}, PULL_UNBALANCE 1 /
PULL_UNBALANCE_WEAK 0.5, UNBALANCE_MIN 0.1. battle/displacement.js: push() holds for its level's row (the −2 correction
included), kept when the 特效 column or a wall shortens the slide [ASSUMED for the wall], the 0.1 s floor when a wall
stops it at the first step [ASSUMED]; pull() holds for its window whatever the travel (≤ −3: none; an enemy the puller
blocks: still no pull [ASSUMED, unchanged]); a 静态刚体 (data staticBody, not 失衡免疫 noDisplace) hit by force level
≥ −2 gets 0.1 s and no movement (_staticForce); _unbalance sets enemy.unbalanceUntil (a longer running one kept) and ends
the attack clip's stand. ai.js updateEnemy: no walking (恐惧 / 诱导 too — PR #392's fear exemption is not taken), no new
normal attack, a swing short of its frame cut, 浮空 clears it; a 重生 clears it (archetypes.js reborn). Not a stun: no
status, no immunity, SP and the attack cooldown run. No global skill lock: enemy abilities keep ticking ([ASSUMED] scope).
The move stays instant (the unbalanced() talents keyed off the jump unchanged). The displace fx carries `dur` (game s);
render/units.js slideTo divides it by ctx.animRate (2× default: a 0.8 s push slides 0.4 real s); DISPLACE_SLIDE·√D is
only the fallback for an fx without it. Not taken from #392: UNBALANCE_TRAVEL 0.6387·√tiles / the client's 0.3194 (derived
from the page's μ = 0.5 单位假设, one frame high on every push row, the wrong shape for pulls) and the fear exemption.
Tests: test/sim/unbalance.test.js (8: the push rows and walking after them; no attack in the hold, a feared enemy held;
the −2 correction's 0.2 s; 特效 / wall-shortened rows and the first-step floor; pull windows incl. the 急停 and ≤ −3; 静态刚体
0.1 s without movement, 失衡免疫 never; 浮空 clears; the fx `dur` — the file fails on the parent); test/render/unitview.test.js
(+1: the slide at 2× for a push and a pull, the fallback — fails on the parent); feedback1b-displacement B5 (the drone is
now held 0.1 s per force, never moved). test/sim + test/content + test/render: 3433 pass. Docs: SIM.md (push / pull,
displace, assumptions), PLAYING.md 推开 / 拉拽, research 13 §0 / §5.

PRTS 守墓石像 / 愤怒的守墓石像: the statue is unblockable, rooted, 失衡免疫 and
immune to 浮空; the reborn flyer is 失衡免疫 (not a 静态刚体, so a persistent
noDisplace buff). PRTS 喷气人: 1.5 s at -90 % speed after take-off, then
1.333 s unblockable at -90 % speed after landing.
PRTS 喷气人: "飞行模式：近地悬浮，不可阻挡，失衡免疫，移动速度+50%，不进行攻击".
The take-off buff gave only 不可阻挡 + speed, so the flying 喷气人 stayed a ground
unit: melee operators hit it and pulls moved it (较大力 vs weight 3: 1.4 tiles).
It is now an air unit that keeps its ground path (flag `float`, as the other
hovering enemies) and is never displaced while it flies.
Player report after 0.1.0: "飞机可以被薄绿的技能拉走". Real. PRTS 特殊机制 静态刚体:
such a unit "可以进入失衡状态…但物理层面上无法产生任何速度或移动", independent of
its movement type. Every air unit of the mode except “炎佑” lists it in its PRTS
天赋, and so does the ground boss 盐风主教昆图斯.
- build-data: STATIC_BODIES (from the enemies' PRTS pages, like HIT_AREAS)
writes enemies.json `staticBody: true` on those 28 keys; data regenerated
- Battle._displaceable: a static body moves 0 tiles from every push or pull;
the skills that reach it still hit it (薄绿 S2, 锏 S3, the hookmasters)
- 刺胄之弹 / 斩胄之剑 / 破胄之锤 also get 失衡免疫 (PRTS 天赋)
- ground enemies keep the 力度 − 重量 tables; the hovering 吉兆飞鳞 / 掠海漂移体
stay 失衡免疫 while they hover and movable once grounded
- tests: the player's scenarios (薄绿 S2 vs 妖怪 / 寒霜, the act2 m01 drone), the
data list, and an audit of every displacement source against ground, static
air, dynamic air, hovering and 胄-shell targets
