arcrun — AI workflow execution engine (clean history)
Self-hosted 開源：WASM 零件 + recipe + cypher-executor，跑在你自己的 Cloudflare。 此為重建的乾淨歷史起點（移除曾誤 commit 的 GCP SA 金鑰，舊歷史保留在 richblack/arcrun 與本地 backup 分支）。含： - acr init --self-hosted installer（建 KV/R2 + codeload 拉預編譯 wasm + wrangler deploy + seed recipe） - recipe push 把關（資料外流提醒 + 打通檢查） - 19 個正當零件預編譯 wasm（claude_api/km_writer/kbdb_upsert_block 排除：違反 DECISIONS §1） - CLI / cypher-executor / registry / 完整 SDD Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

// claude_api — 呼叫 Mira daemon（Hetzner 上跑的 Claude Agent SDK 服務）
|
||||
//
|
||||
// 架構決策（2026-05-06）：
|
||||
// 不直打 Anthropic Messages API（OAuth token 限制 system prompt 角色 → rate_limit_error）
|
||||
// 改透過已部署的 cloud-cto Mira daemon (https://mira.uncle6.me/mira/execute)
|
||||
// 該 daemon 用 Claude Agent SDK，已內建 Mira persona，可長執行任務
