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

// validate_json — u6u 第一個 WASM 零件
// 驗證輸入字串是否為合法 JSON 格式
//
// 白名單 importTinyGo 規範):
// - "os" 只用 os.Stdin / os.Stdout
// - "io" io.ReadAll(os.Stdin)
// - "encoding/json" json.Unmarshal / json.Marshal
//
// 禁止:goroutine、channel、net/*、os.Open、syscall.*、第三方 module
//
// 編譯指令:
// tinygo build -o validate_json.wasm -target=wasi .
//
// 本地測試:
// echo '{"json_string":"{\"key\":\"value\"}"}' | wasmtime validate_json.wasm
// echo '{"json_string":"not-json"}' | wasmtime validate_json.wasm
