uncle6me-web 922a57fe34 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
