- 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.
器物 (the 14 hit-count keys): hits = data × the spawn's hpMul ÷ supplyHpMul, rounded as before (setHits) — 攻坚装备 / II / III
leave out only 炎佑, 补给线 / 补给线II also exactly these 14 keys (activity_table aceffect_enemy_2 / 2_2 enemy_exclude,
data/effects.json); until now setHits(def.maxHp) overwrote the round's HP (青铜镜 30 hits at every difficulty). build-data
writes enemyScale[r].supplyHp = 1.2^(kHp − kAtk) · extra (the HP-only 补给线II steps and 补给线's 1.08; co-op 终极 R5–R15
only — the rebuild changed config.json alone), gamedata returns it as supplyHpMul and the wave / 悬赏 mods carry it
(waves.js roundMods; a 频次 enemy's death spawn inherits it). Not taken from the PR: its 1.08 / 1.2 back-calculation (it
counted the 补给线II steps as 攻坚装备) and its fractional-HP ceiling. Leader summons (死亡集群's 妖怪, 刺胄之弹,
“裂管之音”/“断弦之音”, 不祥幻影): the boss / hidden field carries the round's scale as flags.enemyScale (bossRounds.js,
golden fields, tools/balance.mjs) and bosses.js summonMods gives them HP / ATK / speed (死亡集群's summon.hp_ratio on
top; 刺胄之弹 / 余音 hit counts follow their HP); the leader's pool stays exempt; 王权号令's invulnerable equipment
unchanged; 炎佑 is an ally token, never scaled (no change). Unchanged and open: the 逐火 / 再生 husk counts (talent
prop_max_hp).
Golden — 器物 counts: roster 37 (002 003 004 005 007–020 022 023 025 026 029–034 036–041 043 045 049: each holds a 器物
extra spawn / 频次 wave / death spawn), bond-soloShip-high, diy 9 (036 040 056 062 068 073 091 114 115), boss-boss_6-solo
(俗心's 小说卷轴 escorts); matches 16 (all but solo-ABYSS-2 and coop2-NORMAL-70-diy: 频次 rounds / 悬赏 and the Final
Assault summons). Summons: boss-boss_1-pair/solo, hidden-boss_8-pair/solo (妖怪, 刺胄之弹), boss-boss_3-pair/solo,
hidden-boss_10-pair/solo (余音), boss-boss_5-pair/solo (不祥幻影). standins unchanged.
content/enemies/archetypes.js stealth: an enemy spawned with the band's swap tag 'duck' (content/bands/meta.js
duckReplace) gets its 隐匿 back no sooner than DUCK_STEALTH_RESTORE (1 s, content/enemies/helpers.js) after a block ends
— in practice 流泪小子 (enemy_2034_sythef_2), the only one of the four swaps with 隐匿, officially 0 s (PRTS 流泪小子
「隐匿（解除阻挡0秒后恢复）」). The same enemy anywhere else keeps 0 s: the bounty card's 流泪小子 (enemy_2034_sythef), an
untagged spawn; a 3 s 隐匿 stays 3 s; a copy leaked into 联防 keeps its tag and the 1 s. After each strike (its stunned
blocker lets go) it is now revealed through its 0.8 s post-strike stand and 0.2 s of walking.
Measured, 8 seeds each — leaked / HP left / revealed s per battle; W = 3 elite melee in a lane + an elite sniper vs the
R6 wave's ground enemies with one swapped 流泪小子, B = 8 elites on 战场#01 vs the whole R6 wave with one swap: before
the clip fix W 5/8, 42 %, 2.3 / B 8/8, 47 %, 3.2; after it W 5/8, 31 %, 2.6 / B 8/8, 58 %, 2.5; with the 1 s W 4/8,
31 %, 4.0 / B 8/8, 56 %, 5.5. Options for the owner (measured on the fixed engine, not built): 2 s W 4/8, 31 %, 5.4 /
B 8/8, 46 %, 8.5; 3 s (the general 隐匿 rule) W 4/8, 31 %, 6.4 / B 8/8, 39 %, 11.5; a 1.5 s stun on the copy (below its
2 s interval, so its blocker takes it over again) W 4/8, 2 %, 4.0 / B 4/8, 6 %, 5.5; a 1 s stun: knocked out in all 16;
the 1 s delay + a 2 s stun W 4/8, 21 %, 5.1 / B 5/8, 26 %, 8.1. Worse: half speed while 隐匿; a stunned operator that
keeps blocking it (pins that operator for good).
Golden: matches solo-HARD-2 — its bot holds 鸭爵; the swapped 流泪小子 of round 13 is free and revealed for 49 ticks in
its 1 s windows (the round-12 one is never released by a block), so the match parts at round 13 (a victory instead of
a defeat); the other 282 scenarios unchanged.
Tests: test/content/feedback5-duck-restealth.test.js (3; the swap's 1 s and the band path fail on the parent, the 0 s
guard passes on both); enemies_bosses, feedback2-surtr-stealth, feedback1-ducklord, feedback5-attack-clip-rest pass.
