- 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.
Official: PRTS 琳琅诗怀雅 天赋 破财消灾 备注 「再部署时重置本天赋费用消耗」; the client buff swire2_t_2 multiplies the `cost` in its
own blackboard (CalculateBlackboardValueViaParams × cost_multi) and is rebuilt at each deployment.
Cause: kits/ops/chess_char_3_04-swire2.js kept mem.saveCount for the whole battle. Now: reset on her deploy hook (battle
start, redeploy, 突袭 再部署). 联防 is a battle of its own (fresh units), so its first save always cost 5 — pinned.
Golden: roster-008 (琳琅诗怀雅 elite revived for 5 DP after a redeploy: more DP left, the fight changes), roster-049 (the
same in band 5: snapshot hashes only — DP).
Tests: test/content/feedback5-swire2-revive-cost.test.js (2: the redeploy one fails on the parent, 20 DP instead of 5;
the 联防 one is a pin).
Official: S1 「下一次攻击会为周围八格内血量不足70%的一名友方单位恢复…」; the client charpack (char_1033_swire2, mode S1,
ability HealAlly) selects with range x-4 (the 3×3 with her tile), ally side, _excludeOwner 0, max HP ratio 0.7, one target.
Cause: kits/ops/chess_char_3_04-swire2.js healTarget skipped her (a === unit) and kept only Chebyshev distance 1.
Now: the lowest HP ratio below 70 % of the 3×3, herself included (her own 禁疗 still stops it); the owner's 2026-10-04
cadence (a heal without an attack, once per attack cycle) unchanged.
Golden: roster-027 (琳琅诗怀雅 elite S1 in band 4: she heals herself below 70 %).
Tests: test/content/feedback5-swire2-self-heal.test.js (2, fail on the parent).
PRTS 技能2 备注: placement range x-6 (range_table "x-6": her tile and two tiles in each of the four directions); "若放置
范围内存在敌人，则按攻击索敌规律放置香槟至其所在地块，否则随机放置香槟至可部署的地块". The client charpack (char_1033_swire2,
mode S2) makes her attack a priority composite: SpawnToken (Skill_2) when a free x-6 tile exists and she holds a coin,
else the normal attack. So a coin plus a free x-6 tile takes her attack's turn whether or not an enemy is near; the
tile is the first ground enemy's on a free x-6 tile in her attack target order, else a random free tile. Until now
every attack dropped a bomb at random on her 1-1 attack range. [ASSUMED] the throw costs her attack one tick.
Golden: roster-006 / roster-008, bond-investShip-low, bond-kjeragShip-low, bond-siracusaShip-low,
bond-victoriaShip-low, bond-yanShip-high (each fields 琳琅诗怀雅 with S2) and coop4-ABYSS-7 (a bot fields her from
round 6) moved: her bombs land on x-6 / enemy tiles and are thrown without an enemy.
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.
