- Conflict: docs/PLAYING.md 技能自动释放 bullet — both insertions kept (the 铁钳号 rule from fb7-owner-sim, the #298
pacing sentence).
- Grok review: MERGE AFTER FIXES — the HIGH #298 finding (the cast replaced the due attack) fixed on the branch
(db29acf9: per-skill nextCastAt; golden of #298 alone shrank from 84 scenarios to 2).
- Golden union: 4 matches differ from HEAD though the branch alone left them (coop2-NORMAL-3, coop4-ABYSS-7,
coop2-NORMAL-8-serverrun, solo-HARD-9-boosted): HEAD's side had moved all four (#333's shop RNG …) and on those new
bot paths the merged rules apply — the diffs are in-battle layer gains / damage (卡西米尔 50 → 45, 精准 80 → 76,
叙拉古 176 → 168, kills ±2, solo-HARD-9 LP 397 → 399), no outcome change.
- Broad node --test 5571 (5570 pass, 0 fail, 1 skipped); lint 0 errors; typecheck.
Seen (#364, FrogThai): the 中枢先兆者's shell hit the target and its orthogonal neighbours only — repro: a diagonal
neighbour (√2 ≈ 1.414 from the impact) took nothing, as did a tile two away; the reporter saw the 3×3 in the official game.
Official: PRTS 天赋 of both 先兆者 (one shared kit) 「弹道对半径1.2范围内的所有我方单位造成攻击力100%的无来源物理伤害（此弹道
不会强制击中主目标，碰撞无视迷彩）」. The landing is a 碰撞; PRTS 作战机制 §碰撞体积 (docs/SIM.md, constants.js): collider tests are
the common way and an ally's collider is a 0.25 circle — the rule the engine already applies to ranged enemies' reach.
Now (content/enemies/fly.js kitShell): an ally is hit when its collider touches the 1.2 circle — centre distance ≤ 1.45
(SHELL_REACH = SHELL_RADIUS + ALLY_COLLIDER_RADIUS): the impact tile and the 8 around it, never two tiles away. The
telegraph and the blast are drawn at that reach. [ASSUMED] for this shell (its text names the 碰撞); other content zones
keep their point radius as before. Golden: the three battles with a 先兆者 whose shells land beside a diagonal operator
(roster-001 中枢先兆者, roster-019 and diy-020 先兆者).
Community report relayed by the owner: 炎祐好像吃到了不该吃到的地面伤害. 炎佑 is a flying ally (PRTS “炎佑”
行动方式 飞行). The ground terrain (活性源石), 烹泉 / 沏虹, 庞贝 and 集团军重型火炮 already skipped it, but these
不可对空 effects (PRTS, read for every enemy of data/enemies.json) went through areaAllies / fieldAllies /
targetsNear, which exclude 起飞 allies only:
- 死亡爆炸 of 高能源石虫 / 冰爆源石虫 / 卷心籽 (archetypes deathBoom: `noAir`, on by default; 寒冷 too);
- 水遁忍者 漩涡形态 "每秒对半径1.0范围内的所有我方单位造成…（无视迷彩，不可对空）";
- 鼎沸 "攻击范围内的所有我方单位每秒受到…法术持续伤害与…灼燃损伤（不可对空）";
- “萨科塔昂首” 祈祷邀约 "令全场我方单位（不可对空，无视迷彩）获得15s【受邀祈祷】攻击速度-30";
- “斩胄之剑” / “破胄之锤” "普通攻击对攻击范围内的所有我方单位造成…物理普通伤害，不可对空" (its target rule too).
A ground enemy's normal attack and the 不可对空-free effects still reach it (PRTS: enemies that hit air target it).
Tests: test/content/feedback7-yanyou-noair.test.js (8; all fail on the parent).
- 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.
