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>

# 技術棧硬限制
|
||
|
||
## 三層語言對應(絕對不可混用)
|
||
|
||
| 層級 | 語言 | 位置 | 職責 |
|
||
|-----|------|------|------|
|
||
| 零件(Component) | **TinyGo 或 AssemblyScript → WASM** | `registry/components/{name}/` | 所有業務邏輯 |
|
||
| 零件 Worker 包裝 | TypeScript(固定模板,不寫業務邏輯) | `.component-builds/{name}/` | WASI shim,stdin/stdout JSON |
|
||
| Orchestration Worker | TypeScript + Hono | `cypher-executor/` | HTTP routing、workflow 執行排程、host functions |
|
||
| CLI | TypeScript + Node.js | `cli/` | `acr` 指令 |
|
||
| Python SDK | Python | `python-sdk/` | HTTP thin wrapper + client 端加密 |
|
||
| JS SDK | TypeScript + Web Crypto | `js-sdk/` | HTTP thin wrapper + client 端加密 |
|
||
| Frontend | React 19 + Vite + Tailwind v4 | `landing/` | Cloudflare Pages |
|
||
|
||
## 零件實作規範
|
||
|
||
### 只有兩種合法語言
|
||
- **TinyGo**:`tinygo build -target=wasi -o {name}.wasm main.go`
|
||
- **AssemblyScript**:`asc main.ts --target release -o {name}.wasm`
|
||
|
||
### I/O 模型
|
||
- **stdin**:JSON input
|
||
- **stdout**:JSON output
|
||
- 不用 HTTP server,不監聽 socket(WASI preview1 沒 socket)
|
||
|
||
### Host Functions(零件呼叫外部能力的唯一管道)
|
||
在 `u6u` namespace 下:
|
||
|
||
| Host Function | 用途 |
|
||
|---|---|
|
||
| `u6u.http_request` | 發 HTTP 請求 |
|
||
| `u6u.kv_get` | 讀 Cloudflare KV(Worker 側依 key 前綴路由到正確 KV) |
|
||
| `u6u.crypto_decrypt` | AES-GCM 解密(encryption key 永不暴露給 WASM) |
|
||
| `u6u.crypto_sign_rs256` | RSA-SHA256 簽章(PKCS8 bytes 傳入) |
|
||
|
||
**所有 host function 在 `cypher-executor/src/lib/wasi-shim.ts` 實作**。零件透過 WASI import 使用。
|
||
|
||
## 資料儲存
|
||
|
||
| 儲存 | 用途 | Key 格式 |
|
||
|-----|------|---------|
|
||
| Cloudflare KV `WEBHOOKS` | workflow 定義(cypher binding YAML) | `webhook:{api_key}:{name}` |
|
||
| Cloudflare KV `CREDENTIALS_KV` | 加密 credential | `{api_key}:cred:{name}` |
|
||
| Cloudflare KV `RECIPES` | auth recipe / 動態 API recipe | `auth_recipe:{service}`, `rec_{hash}` |
|
||
| Cloudflare KV `USERS_KV` | 用戶資料 | `user:{api_key}` |
|
||
| Cloudflare KV `SESSIONS_KV` | session | `session:{token}` |
|
||
| Cloudflare KV `ANALYTICS_KV` | 執行分析 | `execution:{timestamp}:{id}` |
|
||
| Cloudflare KV `EXEC_CONTEXT` | workflow 執行中的 context | `ctx:{execution_id}:{node_id}` |
|
||
| Cloudflare R2 `WASM_BUCKET` | **只用於用戶自製零件**(Phase 5 以後啟用) | `{api_key}:cmp:{hash}` |
|
||
|
||
**警告:R2 不存平台內建零件的 WASM**。平台零件已 bundle 進各自的 Worker binary(`[[wasm_modules]]` 或 `import ... assert { type: 'webassembly' }`)。
|
||
|
||
## 加解密規範
|
||
|
||
- **演算法**:AES-GCM 256-bit
|
||
- **加密位置**:Client 端(CLI / Python SDK / JS SDK)
|
||
- Python:`cryptography` 套件
|
||
- JS:Web Crypto API(`crypto.subtle`)
|
||
- **解密位置**:Server 端 **WASM primitive**(透過 host function `crypto_decrypt`)
|
||
- cypher-executor TS **不解密**,只提供 host function
|
||
- `ENCRYPTION_KEY` 只在 Worker host function 內部讀取,**永不經 stdin / 回傳值傳給 WASM**
|
||
- **傳輸格式**:`{ name, encrypted, iv }`(iv base64、encrypted base64)
|
||
|
||
## 網路部署
|
||
|
||
- **平台 API(對外)**:`cypher.arcrun.dev`(cypher-executor)
|
||
- **Landing**:`arcrun.dev`
|
||
- **每個零件 Worker**:
|
||
- **對內(cypher-executor 用來 fetch component,避開同 zone 死鎖)**:`arcrun-{kebab}.{WORKER_SUBDOMAIN}.workers.dev`
|
||
- 例:`arcrun-kbdb-get.uncle6-me.workers.dev`
|
||
- cypher-executor 從 `wrangler.toml [vars] WORKER_SUBDOMAIN` 組出此 URL
|
||
- **對外(可選,零件對全網開放被 curl 用)**:`{kebab}.arcrun.dev`
|
||
- 例:`gmail.arcrun.dev`、`kbdb-get.arcrun.dev`
|
||
- 仍允許保留,但**禁止 cypher-executor 透過此 URL fetch**(會撞同 zone 自循環,見 [docs/incidents/2026-05-13-cypher-outbound-522.md](../../docs/incidents/2026-05-13-cypher-outbound-522.md))
|
||
- **新增 component worker 部署清單**:`name = "arcrun-{kebab}"` + `[[routes]]` 對外(可選)+ dashboard 啟用 workers.dev(必須)
|
||
- **部署工具**:Wrangler
