Better-auth's default password hasher is @noble/hashes scrypt (pure JS), which consumes ~100-200ms of CPU per call. Cloudflare Workers' free tier caps each request at 10ms of JS CPU time, so sign-up/sign-in consistently fails with error 1102 after the initial cold-start burst budget runs out. See better-auth/better-auth#8860 for the upstream bug. Override emailAndPassword.password.hash/verify with node:crypto.scryptSync. The native OpenSSL implementation runs in ~ms of wall time and is counted as I/O rather than JS CPU time on CF Workers, so it does not touch the CPU budget. Works identically on the Node/Docker entry because node:crypto is native there too. Verified end-to-end on https://af9a6fdc.zpan.pages.dev: 5 sequential signups + 5 sequential signins all returned HTTP 200 (previously 4/4 consecutive signups hit error 1102 on the same deployment).
