feedback7 R22-UNBAL: 失衡 review fixes — a pulled 静态刚体 is held for the pull's window, 弧光锋卫 bleeds 400 every 0.066 s while the state lasts, no enemy skill / blink / scripted move during it, a route APPEAR or a 逐火 重生 ends it, every push row holds its exact frames; golden: 32 move, 8 in outcomes (below)

Branch review of fb7-unbalance (MERGE AFTER FIXES):
1. A 静态刚体 pulled got the 0.1 s floor: _staticForce now knows push from pull — a push's force is instant (推与拉), so
   0.1 s; a pull's lasts its window (pullUnbalance: 1 s, 0.5 s below −1) — PRTS 特殊机制 静态刚体 「在失去施力后立刻」 out,
   「0.1 秒保底」. pull() checks the puller's own block before the static case.
2. 弧光锋卫 (PRTS 天赋 「处于失衡状态时，每0.066s受到400点无来源真实持续伤害」, data unbalanced_bleed): a tick bleed of 400 every
   0.066 s while unbalancedNow holds; the per-tile one-shot from the position jump ([ASSUMED], UNBALANCE_SPEED) is gone.
   A 受力等级 0 push (0.8 s) → 12 hits = 4800 (was 2037), a 急停 pull with no movement (1 s) → 15 = 6000 (was 0), a
   wall-shortened slide keeps the 0.8 s row → 4800.
3. 失衡免疫 「失衡期间无法自主移动、发动攻击、使用技能」: enemies/helpers.js unbalancedNow; canCast(e, sil, battle) refuses while it
   runs (content skills; the boss parts' calls pass the battle), blinkForward returns null, 枯朽之种's dive / blast and the
   铳 / 碎铳之簧 charges wait, 乌顶巨角卢鲁's clash waits for its end. A route APPEAR relocation clears it (a forced state
   switch, 失衡位移机制). Left running on purpose (docs/SIM.md): 水遁忍者's damage check (异常效果 「仍然能正常造成伤害」), passive
   auras and terrain / periodic effects, death / damage-taken triggers, skill cooldowns, 弧光锋卫's bleed itself.
4. husk() (逐火 余烬 重生) clears the state like reborn().
5. The 35/30 row held 36 frames (t0 + 35/30 overshoots in floats): every check compares with 1e-9; the frames are asserted.

Tests: test/sim/unbalance.test.js +6 (exact frames 6 / 12 / 24 / 27 / 32 / 35 with the walk on the next frame; static pull
1 s / 0.5 s, push 0.1 s; 弧光锋卫 4800 / 6000 / 4800; canCast / blinkForward refused, 枯朽之种 held then diving; the elk's clash
after the state; APPEAR and a 逐火 重生 clear it — all six fail on the parent); enemies_bosses (失衡 kit test) and
feedback1d-solvent (BUFF damage) updated to the state bleed. test/sim + test/content + test/render pass. Docs: SIM.md
(push / pull row), PLAYING.md, design/engine.md (helpers, enemy AI), constants / displacement comments.

Golden against the previous commit — outcome moves: roster-010 (歌蕾蒂娅 pulls 妖怪 drones, now held 1 s: killed 44→45,
leaks 58→57), roster-040 (static pulls of 妖怪: killed 28→25, leaks 37→40, deaths 29→30), roster-043 / 044 (山: deaths 14→16 /
14→13), hidden-boss_9-pair (锏: boss HP 3636991→3586929), coop4-ABYSS-7 (ai_2 LP +1 from round 5), diy-115 (黑键: leaks
70→75), diy-116 (黑键: killed 2→3, leaks 121→120) — the static pulls (probe) and the 1e-9 end (a frame shorter where the float
sum overshot: the 35/30 row, some pull windows); other moves (damage / snapshots only): roster-008 / 017 / 039, 9 bonds,
boss-boss_4-pair / boss_6-pair / hidden-boss_10-pair, coop2-NORMAL-14-standins / coop2-NORMAL-3 / solo-ABYSS-1 /
solo-HARD-1 / solo-HARD-9-boosted / solo-NORMAL-1, diy-053 / 085 / 102.
