feedback7 R22-UNBAL: a pushed / pulled enemy is held in the official 失衡 (UNBALANCE) state — no walking, no normal attack — for the push's 位移时间 of its 受力等级 or the pull's force window; a 静态刚体 hit by a force gets the 0.1 s floor; the client's slide takes the same game time (idea from PR #392 by @xcdoge, re-implemented from the sources); golden: 69 scenarios move, 35 with kills / leaks / deaths / boss HP (below)

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.
