PRTS 异客 S3 备注: 「开启技能时选择技能范围内的目标，以其判定中心所在格为中心生成一个x-1的雷暴区域」; range_table x-1 is the
13-tile diamond (|Δrow| + |Δcol| ≤ 2); x-3 (|技能范围|) stays the search range. The storm's tile is the rounding of the
target's centre (body.js posKey), fixed for its 4 s; a strike picks among the enemies she can select whose body is on
those tiles (enemiesInKeys, as her other range checks); each strike still chains on its own bounce radius. The fx ring is
drawn at radius 2 (visual only). Until now: [ASSUMED] radius 1.5 around the target's exact position — an enemy two tiles
straight off the target's tile was never struck, one at (+1.55, +1.05) off the tile centre was.
Re-implemented from the PR's claim (its golden files were not taken). Golden: every moved scenario fields 异客 casting
S3 — the zone holds other enemies and the random pick draws from another list.
- 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.
Pure move: every line of a kit, of a helper and of the tier headers is copied verbatim (only the headers' first
line names the new file); a helper used by one kit moved into that kit's file. Glue only: the generated imports,
`export default { … }` around each registry entry, `export { … }` lists in shared/tier2..6.js, and tier4's
`(bb, chess, def)` default-argument wrapper as shared/tier4.js `withDefaults` (applied in each tier-4 kit file).
kits/index.js loads every kit file with a guarded dynamic import (browser-safe, no directory listing); tierN.js
re-export the tier registry (TIER_KITS) and their old named exports (tier1 helpers + tinmanKit, tier6
PITHST_ELEMENTS). The merged registry, every tier default and named export have the same keys, order, frozenness
and function sources as before. test/docs-consistency.test.js reads the moved code at its new paths.
Golden: GOLDEN_FULL=1 node --test test/golden.test.js unchanged.
