- 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.
