- 沙箱改用 quickjs-emscripten singlefile variant(wasm 內嵌 base64、同步載入), CF Workers 相容;sandbox.mjs 成 Node/Worker 共用 runtime-agnostic 核心。 - sha256 curated builtin 改「純 JS SHA-256 prelude 字串注入」,去掉 node:crypto / async Web Crypto host-call,Node/Worker 皆決定性(card content_hash 逐字等價)。 - index.ts 成可部署 Worker host(Hono,POST /→runCode),自足不走 TinyGo 模板流程。 - 補 wrangler.toml(arcrun-code / code.arcrun.dev)、tsconfig、DEPLOY.md。 - contract stability 修為 floating(過 registry zod schema 驗證)。 - 單測 12/12 全綠(含 card→envelope 與原模組 planCard 逐欄全等)。 Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01HJiLCRUU2o3aSpPEzVCt2o

通用「程式碼逃生口」。跑一段 sandbox inline JS(n8n Code node 式):
|
||
config 帶 `code`(inline JS 函式體),stdin 帶 `input`(上游 JSON),
|
||
stdout 回 `{success, data}` 或 `{success:false, error, error_type}`。
|
||
user code 在 QuickJS-wasm 沙箱內執行,只有純 ECMAScript 內建 + host 明確注入的
|
||
curated builtin(目前:純函式 sha256),碰不到網路/檔案/env/secret/Worker 物件圖。
|
||
用於一次性/小段程式邏輯(如卡片→envelope 文字處理),避免各自鑄 domain 零件。
|
||
config_example: |
|
||
my_code: # 節點名稱(可自訂)
|
||
code: | # inline JS 函式體(必填);讀 input、return 一個 JSON-able 值
|
||
const doubled = input.items.map(x => x * 2);
|
||
return { doubled, count: doubled.length };
|
||
input: # 上游資料(選填;workflow 可用引用注入)
|
||
items: [1, 2, 3]
|
||
limits: # 資源上限覆蓋(選填)

timeout_ms: 2000
