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>
