- server/sim/detmath.js: hypot (sqrt of the squares, rescaled outside 2^±500), powi (integer powers in double-double,
one rounding), sin / cos (fdlibm 5.3) and atan2 (fdlibm / FreeBSD msun) built only from correctly rounded IEEE
operations; the sim's Math.hypot / sin / cos / atan2 / pow calls go through it (65 files); eslint.config.js forbids
the approximated Math functions under server/sim and test/sim/detmath.test.js scans for them.
- sin / cos / atan2 are the algorithms V8 runs in Node, so the server's results stay; only hypot differs from V8's.
Golden: 2 moved — diy-027 (a hypot distance, damage +80) and coop3-ABYSS-5 (a later card pick from round 9, same end).
- Applied unchanged after review (Grok static review: MERGE; the diff read in full: no network, no new dependency).
- Tests: broad node --test 5155 / 5155 with the new file tracked (detmath 7 / 7, package 10 / 10); lint 0 errors,
typecheck, check:imports.
The 「投石车」 is 自制投石机 (enemy_10162_mnctpt), the 「蒸汽地板」 the 排气格栅 smog (隐匿 to enemy ranged attacks). PRTS
天赋 「索敌不受阻挡影响」: the blocker exception (a blocked enemy attacks its blocker whatever its selectability) does not
apply to it. New enemy profile field `blockFree` (spawns.js): attackTargets selects as if unblocked, canTargetAlly
refuses a 隐匿 / 迷彩 blocker to it, sortAllyTargets puts no blocker first. Other enemies unchanged.
Golden: standin-06 (the bounty catapult, blocked by 忍冬, now shoots by 仇恨值 — checked instrumented).
Tests: test/sim/feedback5-catapult-smog.test.js (3; 2 fail on the parent). Docs: DESIGN §25.18.7, docs/SIM.md.
Official: PRTS 天赋 and the battle prefab's templates (dlancer_t_listener[a/b/c] every 0.1 s: STUNNED / UNMOVABLE end
dlancer_t[trigger], not blocked starts it; a MULTIPLIER layer every 0.5 s up to 25 tries, blocked or not;
dlancer_t_atk: DamageViaAttr MOVE_SPEED × 600, physical, ignoreForSp, then ends the trigger). Until now it kept
accelerating through a stun and kept the speed, and the hit was one attack multiplied ×(1 + 6 × layers / 25), a stun
in between included. A slow is no reset (official).
Golden: 6 scenarios, each with 萨卡兹穿刺手: roster-016, standin-04, standin-08, diy-028, diy-124, coop2-HARD-4.
Tests: test/content/enemies_bosses.test.js (3, fail on the parent). Docs: DESIGN §25.18.6.
ba.groundbind "目标变为地面单位，无法移动；使部分近地悬浮敌人掉落；对重量大于3的单位持续时间减半" (予愿安洁莉娜 S2 needs it):
- buffs.js: STATUS groundbind (flag groundbind + noMove, move x0), FLAG_KEYS, RESIST_STATUSES (as 束缚, [ASSUMED]);
- units.js isFlying: an enemy under 缚地 is a ground unit unless a 浮空 lifts it (same result as before without the flag);
- battle/status.js: 浮空 lands on a 缚地 data flyer (PRTS 异常效果 "…且不持有缚地异常…则Buff取消"), 缚地 halved on weight > 3;
- content/enemies: 掠海漂移体 / 吉兆飞鳞 drop on 缚地 as their PRTS text says (吉兆飞鳞 stays down while it holds);
- render/style.js: the 束缚 icon for it; docs/SIM.md (§2 isFlying, §3 flags / status table / 抵抗).
Nothing applies it yet: every golden family is unchanged. Test: test/sim/feedback5-groundbind.test.js.
