fix(cypher): auth primitive 改走 service binding(解 self-hosted CF 1042)
壓測階段 11:self-hosted 帳號 cypher 用 fetch(workers.dev) 打同帳號 auth worker 被 CF 子請求限制回 1042,service account token 換不到 → 表單寫不進 Google Sheets。token/解密鏈本身正常(直打 auth worker 回真 ya29)。 架構演化(richblack 2026-06-06 拍板):用戶產生的是 recipe(KV 資料,不 deploy), primitive 是平台固定基礎設施、用戶不新增 → 解除「auth primitive 禁 service binding」 舊禁令。service binding 是 CF 內部 RPC,繞開同 zone 522 + 同帳號 workers.dev 1042。 - wrangler.toml:加 SVC_AUTH_STATIC_KEY/SERVICE_ACCOUNT/OAUTH2(已部署者;mtls 未部署留註解) - auth-dispatcher.ts:binding 優先 svc.fetch(),無 binding fallback fetch(workers.dev) - types.ts:4 個 optional SVC_AUTH_* - deploy.ts 無需改:stripOfficialOnlyBindings 不碰 services,tier1 auth 先於 tier2 cypher - 已驗證 self-hosted(leo21c)13 邏輯零件 binding 實綁成功,auth binding 走同路 規範同步:rule 02 / 03 / CLAUDE.md / pre-bash-guard 例外。SDD: Phase 7。tsc exit 0。 Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
