The contributor's code (server/sim/content/traitMods.js, the battle/players.js _setupUnit wiring after kit.install, the
crowdAspd removal from shared/tier5.js and the two kits, test/sim/trait_attack_speed.test.js), applied from PR #293, so
they are the author of this commit. Maintainer additions: the coverage lock also scans the 补位 stand-ins (266) and every
legal 自选 combination (pool operator × slot form × skill × non-other-mode module) — none gains the rule; 黑键 / 维伊
MSC-Y 「拥有已储存的攻击能量时，攻击速度+30」 (their 自选 kits own it) is listed as kit-owned instead of 'unknown'; the
comment's history note named a commit this repository does not have, and its line-number references are now names;
docs/ARCHITECTURE.md and kits/README.md name the file.
Official: battle_equip_table uniequip_003_excu2 (display trait + hidden talent attack_speed 12, trigger_cnt[equip] 2) and
uniequip_003_etlchi (trait attack_speed 12, cnt 2), both 「攻击范围内存在2名及以上敌人时攻击速度+12」; 仇白's
uniequip_003_qiubai carries the same sentence on her named talent, which her kit keeps reading (not seen by the engine).
Before: shared/tier5.js crowdAspd polled every 0.2 s and gave a 0.3 s buff — measured +12 0.167 s after the second enemy
arrived and 0.267 s after it died (scratchpad repro); now one tick each. Golden: unchanged (no sampled snapshot moves).
- 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.
