+# 143 开发目录 Memind-dev
+
+> 在 Mac Studio（103，`john@180.159.29.143`）上与本地 Mac 并行开发 Memind 的约定。  
+> 生产运行目录仍是 `/Users/john/Project/Memind`；**日常改码只用** `/Users/john/Project-dev/Memind-dev`。
+
+## 目录对照
+
+| 机器 | 开发目录 | 生产 / 103 运行目录 |
+|------|----------|---------------------|
+| 本地 Mac | `/Users/john/Project/Memind` | — |
+| 143 | `/Users/john/Project-dev/Memind-dev` | `/Users/john/Project/Memind` |
+
+代码同步靠 Git 远端 `git@git.tkmind.cn:tkmind/memind.git`，不要用 rsync 拷源码。
+
+## 143 开发端口（与生产隔离）
+
+| 服务 | 生产 | Memind-dev |
+|------|------|------------|
+| Portal / API | 8081 | **8086** |
+| MindSpace H5 (Vite) | — | **5173** |
+| memind_adm | 8082 | **8087** |
+| Ops | — | **3003** |
+| Plaza | 3001 | **3004** |
+
+`.env` 在 Memind-dev 内单独维护（从生产 `.env` 复制后覆盖上表端口与 `MEMIND_RUNTIME_PROFILE=local`），**不要** commit。
+
+## 日常命令
+
+```bash
+ssh john@180.159.29.143
+cd /Users/john/Project-dev/Memind-dev
+source ~/.zshrc          # 加载 /opt/homebrew 的 node@22 / pnpm
+git fetch origin --prune
+git pull --ff-only
+pnpm install             # 仅 lockfile 变化时
+pnpm dev
+```
+
+本机浏览器经 SSH 隧道访问 143 上的 Vite：
+
+```bash
+ssh -L 5173:127.0.0.1:5173 -L 8086:127.0.0.1:8086 john@180.159.29.143
+# 然后打开 http://127.0.0.1:5173/?preview=mindspace
+```
+
+Cursor Remote SSH：打开文件夹 `/Users/john/Project-dev/Memind-dev`。
+
+## 双机同步流程
+
+**收工（任一台）：**
+
+```bash
+git status
+git add -A && git commit -m "..."
+git push origin feature/learn-assistant   # 或 main，需明确批准 push
+```
+
+**开工（另一台）：**
+
+```bash
+git fetch origin --prune
+git switch feature/learn-assistant
+git pull --ff-only
+```
+
+## Git SSH（143 必配）
+
+143 公钥需加入 `git.tkmind.cn`（端口 2222，见 `~/.ssh/config`）：
+
+```bash
+ssh john@180.159.29.143 'cat ~/.ssh/id_ed25519.pub'
+ssh -T git@git.tkmind.cn   # 在 143 上验证
+```
+
+未配公钥前，可临时用本机 `git bundle` 同步，但不建议长期使用。
+
+## 103 发布
+
+- 功能合并进 `main` 且 CI / verify 通过后，在 **生产目录** 拉最新 `main` 再跑发布脚本。
+- 禁止从 Memind-dev 脏工作区或功能分支直接 `release-portal-*-prod.sh`。
+- 发布前：`bash scripts/check-release-ready.sh`
+
+## 注意
+
+1. 两台机器不要长期各改同一分支却不 push/pull。
+2. Memind-dev 与生产共用 `DATABASE_URL` 时，开发操作可能影响线上数据，谨慎执行 destructive 脚本。
+3. `pnpm dev` 与 103 生产 Portal（8081）可同时存在；不要误改生产目录下的文件或重启生产 LaunchAgent。

+
+**状态：禁止再次引用。已 fast-forward 并入本地 `main`（`2c3c1f7a`），103 已热更新 `wechat-mp.bundle.mjs` 与超时 env；完整 Portal runtime 与 `origin/main` push 待后续闭环。**
+
+审计日期：2026-09-11
+分支 HEAD / 本地 `main`：`2c3c1f7a`
+
+### 原始用途
+
+微信服务号 `page.generate` 在 Goose 直连超时（`WECHAT_AGENT_REPLY_TIMEOUT`）后，由 Cursor 接手重试；默认超时从 15 分钟提升至 20 分钟。
+
+### 验证摘要
+
+- `node --test wechat-mp.test.mjs wechat-cursor-page-timeout-takeover.test.mjs cursor-page-timeout-takeover.test.mjs`：186 passed
+- 103：`deploy-wechat-mp-prod.sh` 上传 bundle（2026-09-11 15:32）；`.env` 已设 `H5_WECHAT_MP_AGENT_REPLY_TIMEOUT_MS=1200000`、`MEMIND_CURSOR_PAGE_TIMEOUT_TAKEOVER=1`；Portal 8081 健康 200
+
+### 103 发布记录（部分）
+
+- 热更新：`wechat-mp.bundle.mjs`（含 `executeCursorTakeoverRun` / `WECHAT_AGENT_REPLY_TIMEOUT` 接手逻辑）
+- 未走完整 runtime 包：当前 manifest 仍为 `20260911-134117-cb3fb352`；`agent-run-gateway.mjs` 的 `getToolGatewayStatus` 导出不在 bundle 内（微信接手有 env 回退）
+
+### 最终处置
+
+- 保留本地分支名用于审计追溯。
+- 不要从该分支继续开发、merge、cherry-pick 或构建 runtime/artifact。
+- 后续若需完整对齐：push `origin/main` + `release-portal-fast-prod.sh`。
