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>

// G1 假零件偵測(component-gatekeeping SDD,R2)
|

//
|

// 判準(DECISIONS §1):零件若滿足任一,是假零件,該降級成 recipe / 工作流:
|

// (a) contract 或 wasm binary 出現具體外部服務 URL / domain
|
||||
// (b) 宣告能力是 http_request 子集(打某固定 endpoint)

// Q2 決議(richblack 2026-05-29):兩者都「硬擋」(不是只 warn)。

## TinyGo 白名單 {#tinygo-whitelist}
|
||||
|
||||
第一波內部零件使用 TinyGo 開發。**只允許**以下 import:
|
||||
|
||||
\`\`\`go
|
||||
import (
|
||||
"os" // 只用 os.Stdin / os.Stdout / os.Stderr
|
||||
"io" // io.ReadAll(os.Stdin)
|
||||
"encoding/json" // json.Unmarshal / json.Marshal
|
||||
)
|
||||
\`\`\`
|
||||
|
||||
### 允許的操作
|
||||
|
||||
- \`io.ReadAll(os.Stdin)\` 讀取 input JSON
|
||||
- \`json.Unmarshal\` 解析 input
|
||||
- \`json.Marshal\` + \`os.Stdout.Write\` 輸出 output JSON
|
||||
- 基本型別操作(string、int64、float64、bool、[]byte、map[string]interface{})
|
||||
- 錯誤用 stdout 輸出:\`{"error": "說明"}\`,不要 panic
|
||||
|
||||

|
||||
|
||||
## 禁止行為 {#forbidden-behaviors}
|
||||
|
||||
以下行為會導致沙盒驗收失敗:
|
||||
|
||||
- **網路 syscall**:\`net/*\`、\`sock_connect\`、\`sock_accept\` 等
|
||||
- **檔案系統 syscall**:\`os.Open\`、\`os.Create\`、\`path_open\` 等
|
||||
- **goroutine / channel**:WASM 環境不支援
|
||||
- **syscall.*\`**:任何直接 syscall
|
||||
- **第三方 module**:只用標準庫
|
||||
- **打包 runtime**:不得打包 QuickJS、Node.js 等
|
||||
- **超過 2MB**:體積上限 2048KB
|
||||
- **混合前後端邏輯**:一個零件只做一件事
|
||||
|
||||
---
|
||||
|
||||
## I/O 模型 {#io-model}
|
||||
|
||||
唯一合法的 I/O 模型:\`stdin_stdout_json\`
|
||||
|
||||
\`\`\`
|
||||
stdin → JSON.stringify(input) → 零件讀取
|
||||
stdout ← JSON.stringify(output) ← 零件輸出
|

# 預期輸出:{"valid":false,"error":"..."}
