+        角色 dadao_prod_app（RLS）
+        角色 dadao_prod_owner（迁移）
+```
+
+为什么是这个形状：
+
+- **生产库和开发库在同一个 PG 实例**（fnsvr-01），所以生产用**独立的库 + 独立的角色**。复用 `dadao_app` 等于拿到开发口令就能连生产。迁移里的 `GRANT`/`DEFAULT PRIVILEGES` 按 `APP_DB_ROLE` / `OWNER_DB_ROLE` 生成，靠 `backend/app/roles.py` 注入。
+- **Redis 用 6 号库**隔离：共享实例没有密码，靠库号避免和别的项目撞键（验证码、幂等键）。
+- **没有 nginx**：openclaw 账号无 sudo 密码，改不了系统 nginx，所以后端单端口同时托管 API 与前端产物（同源，免 CORS）。root 愿意配合时按 `deploy/prod/nginx.dadaotask.conf.example` 加反代，不用改应用。
+- **用户级 systemd**：openclaw-01 上所有服务（easymemo、portal-site…）都是 `systemctl --user` 起的，本方案沿用，全程不需要 root。
+
+## 2. 首次部署（一次性）
+
+前置：能 SSH 到 openclaw-01；fnsvr-01 的 root 权限（只在建库这一步需要）。
+
+### 2.1 建生产库与角色（在 fnsvr-01 上，root）
+
+```bash
+# 口令自己生成，别用示例里的
+OWNER_PW='<dadao_prod_owner 的口令>' APP_PW='<dadao_prod_app 的口令>' \
+  bash deploy/prod/provision-db.sh
+```
+
+会创建：库 `dadaotask_prod`（owner `dadao_prod_owner`）、角色 `dadao_prod_owner` / `dadao_prod_app`（`NOSUPERUSER NOBYPASSRLS`，否则 RLS 会被跳过）、`public` schema 归 owner、`REVOKE CREATE ... FROM PUBLIC`。建表与 RLS 策略由 alembic 负责（2.4）。
+
+### 2.2 代码落地（在 openclaw-01 上，openclaw 身份）
+
+```bash
+git clone --branch main --single-branch http://gitea.tatta.cn/Tatta/DadaoTask.git ~/app/dadaotask
+```
+
+### 2.3 配置（不进仓库）
+
+```bash
+mkdir -p ~/.config/dadaotask && chmod 700 ~/.config/dadaotask
+cp ~/app/dadaotask/deploy/prod/env.production.example ~/.config/dadaotask/env.production
+chmod 600 ~/.config/dadaotask/env.production
+vim ~/.config/dadaotask/env.production        # 替换全部 __CHANGE_ME__
+```
+
+必填项：`DATABASE_URL` / `MIGRATION_DATABASE_URL`（2.1 的口令）、`JWT_SECRET`（≥32 位随机串）、`REDIS_URL`、`WEB_DIST_DIR`、`UPLOAD_DIR`。
+
+**当前状态是内测模式**：短信通道还没接（非 dev provider 直接 501），所以 `SMS_PROVIDER=dev` + `INTERNAL_TEST_LOGIN=true`，固定验证码 `123456`。启动日志会打 WARNING。**只允许内网访问**；短信通道接好后删掉 `INTERNAL_TEST_LOGIN` 并把 `SMS_PROVIDER` 换成真实供应商。
+
+### 2.4 装服务单元
+
+```bash
+mkdir -p ~/.config/systemd/user
+cp ~/app/dadaotask/deploy/prod/dadaotask-api.service ~/.config/systemd/user/
+systemctl --user daemon-reload
+```
+
+### 2.5 首次上线
+
+```bash
+bash ~/app/dadaotask/deploy/prod/deploy.sh
+```
+
+## 3. 日常发布（每次上线）
+
+```bash
+# 本地：提交并 push 到 main（生产只跑仓库 HEAD）
+# 服务器：
+bash ~/app/dadaotask/deploy/prod/deploy.sh
+```
+
+脚本做六件事，任何一步失败即中止：代码对齐 `origin/main`（`git reset --hard`，禁止服务器手工改）→ 装 Python 依赖 → `alembic upgrade head`（用迁移角色）→ **在服务器上** `npm ci && npm run build` → 写 `env.build` 并重启 → 校验 `/health` 与 `/version` 的 commit 等于 HEAD。
+
+前端产物只在服务器上构建，**不允许**本地上传 dist（AGENTS.md 铁律 3）。
+
+## 4. 部署后校验
+
+```bash
+curl -s http://192.168.8.188:8200/health          # {"status":"ok","db":true,...}
+curl -s http://192.168.8.188:8200/version         # commit 必须等于 git rev-parse --short HEAD
+curl -sI http://192.168.8.188:8200/ | head -1     # 200，text/html（前端产物）
+```
+
+浏览器验收：打开 `http://192.168.8.188:8200` → 手机号任意 + 验证码 `123456` 登录 → 任务/工单/知识各点一遍。
+
+## 5. 运维
+
+```bash
+systemctl --user status  dadaotask-api      # 状态
+systemctl --user restart dadaotask-api      # 重启
+journalctl --user -u dadaotask-api -f       # 日志（gunicorn 输出到 stdout）
+```
+
+- 附件落盘：`backend/var/uploads`（按工作区分子目录），删库不删文件，备份时一起打包
+- 回滚：`cd ~/app/dadaotask && git reset --hard <旧 commit> && bash deploy/prod/deploy.sh`；**数据库迁移不回滚**，回滚代码前确认旧代码兼容新表结构
+- 端口：`8200`（systemd 单元与 `deploy.sh` 的 `PORT` 默认值，两处要一致）
+
+## 6. 已知限制（当前阶段）
+
+| 限制 | 影响 | 解除方式 |
+|---|---|---|
+| 没有 HTTPS / 域名 | 只能内网 IP 访问，令牌明文传输 | 域名 + nginx + 证书（需 root） |
+| 内测固定验证码 | 谁都能用任意手机号登录 | 接短信通道，关 `INTERNAL_TEST_LOGIN` |
+| 无 pgvector | 语义检索走 `real[]` 全表扫描，数据量大了会慢 | 上独立 pgvector 实例（`deploy/docker-compose.vector.yml`） |
+| 上传目录在本机磁盘 | 机器坏了附件就没了 | 备份 `backend/var/uploads`，或将来到对象存储 |

+| 3.11 | 知识分类：工作区三级小树（`knowledge_category` + 迁移 0007 + RLS），知识可归一类，列表按分类子树 / 未分类 / 标签筛选 | 1.0 | [x] 增删改移 + 重名 `7008`、超三级 `7007`、删分类要 `force` |
+| 3.12 | 备忘录形态：新建知识一次写全（标题/类型/分类/标签/正文），不再是"填个标题就完成"；抽屉加宽 + 可整屏 | 1.0 | [x] Web `KnowledgeComposer` + 安卓新建后直进编辑器；正文就是详情同款富文本编辑器（Vditor / Compose 编辑器）；`Sheet` 增 `size="md/lg/xl"` 与展开按钮；截图 `2.Design/screens/knowledge-composer.png`、`knowledge-categories.png` |
+| 3.13 | 知识能挂附件：新建面板里直接上传（懒建草稿拿到条目 id 再传），详情里能看、能下载/打开 | 1.0 | [x] Web `AttachmentPanel` + `RichTextEditor.ensureItemId`（贴图/传附件前自动存草稿）；安卓详情页附件列表 + `OpenDocument` 上传 + 浏览器打开；附件仍落在 `item` 上（`ALLOWED_KINDS` 含 knowledge） |

 ### M3 完成定义（DOD）
 - [x] 一件事办完 → 自动出现一份草稿 → 核对 → 发布，全程不用手动复制粘贴
 - [x] 每条知识都能追到来源（除手记），点开能看到来源事项
 - [x] 非管理员发布被拒；跨租户看不到别人的知识
+- [x] 知识是备忘录：标题、正文、标签、三级分类、搜索；新建时就能把这些一次填完（Web 与安卓一致）
 - [x] 切片与语义检索跑通（`real[]` + SQL 余弦；pgvector 仍待独立实例）
 - [ ] 真实用两周：新同事靠知识库自己解决过一次问题（需要真实团队）

+"""知识分类（M3 补充）

+Revision ID: 0007

+Create Date: 2026-10-30
+
+知识库的基本形态是"备忘录"，不是"任务"：一条知识要有标题、正文、标签，
+还要能归类。这里补上分类树（一级大类 / 二级 / 三级，深不过三）。
+
+两个取舍：
+
+1. **分类独立成表，不塞进 item**。分类是工作区级的字典，一条知识挂一个分类；
+   塞进 item 会让"分类"变成每条知识自己的一份副本，改个名字要改几百行。
+2. **删分类不删知识**。外键是 `ON DELETE SET NULL`：知识退回"未分类"，
+   分类只是入口，不是知识的容器。真要连内容一起删，那是删知识，得单独确认。

Steven	ffae7e380f	fix(knowledge): PATCH 知识时带上 doc_type 直接 500 `patch_knowledge` 把 `doc_type`/`summary` 也塞进了给 `items` 表的 UPDATE，于是 SQLAlchemy 报 `CompileError: Unconsumed column names: doc_type`——改类型的请求一律 500。这两个字段本来就属于 `knowledge_doc`，下面几行已有赋值，重复写进 items 的 values 是错的。现在 `values` 只放 items 的列（title/body_md），`doc_changed`（doc_type/summary）单独参与"要不要推进 version"的判断，语义不变：只要这条知识的样子变了， version 就得 +1，否则下一次保存会拿旧 version 撞 4009。补一个用例：PATCH 同时改 title/body_md/doc_type/tag_names 应该 200， doc_type 生效、version 前进一步。这个 bug 之前没暴露，是因为 Web 抽屉只改标签和分类，没人用 PATCH 改过类型。	2026-10-30 16:18:05 +08:00
Steven	9a382e4e8c	fix(knowledge): 新建知识的正文换成富文本编辑器，不再是纯文本框 CI / backend (push) Canceled after 0s Details 「记一条」面板里正文是个 textarea，排版、表格、贴图都没有——创建时反而比详情页更寒酸。现在新建面板直接用详情同款 Vditor 编辑器，创建与修改一个模样。 - `RichTextEditor` 的 `itemId` 改为可选：新建时还没有条目 id，正文照写，只是上传按钮不摆出来；真去贴图会提示「先保存这条内容，再回来贴图」。 - `KnowledgeComposer` 的正文换用 `RichTextEditor`（minHeight 320），页脚提示按有没有条目 id 给不同文案。 - 安卓：新建对话框不再放纯文本正文框，保存后直接进 `RichTextEditorScreen` 写正文（排版、表格、贴图都在那儿），写完回到列表并展开详情。 - e2e 增加一条断言：新建面板里的正文就是富文本编辑器（aria-label=正文的 contenteditable），正文按真实键盘输入后 Markdown 正常落库。验证：`tsc --noEmit` 通过、`vite build` 通过、`knowledge-notebook.mjs` 11 项全绿（新增「新建面板的正文是富文本编辑器」）。安卓端本机仍是 JDK 25 + Gradle 8.7/AGP 8.7.3 不兼容，本次未编译验证。	2026-10-30 15:52:09 +08:00
Steven	ed31af3f46	feat(knowledge): 知识改成备忘录形态，一次写全 + 三级分类，抽屉加宽 CI / backend (push) Canceled after 0s Details 知识以前只能"填个标题就完成"，正文、标签、归类都要点进去再补。现在新建就是一张完整的备忘录：标题、类型、分类、标签、正文一次写完，存完直接打开详情继续编辑；知识页左侧多了工作区三级分类树，可按分类子树 / 未分类 / 标签筛选。凡是填信息的抽屉都加宽了，还能一键展开整屏。后端 - 新增 `knowledge_category`（迁移 0007）：`workspace_id NOT NULL` + 自引用 `parent_id`、`depth` 1..3 检查约束、同层重名唯一索引（lower(name)）、 RLS 策略与 `dadao_app` 授权；`knowledge_doc.category_id` 外键 ON DELETE SET NULL。 - 新增 `/knowledge/categories` 增删改查：超三级 `7007`、同层重名 `7008`、跨租户或不存在 `7006`；`move=true` 才改父级，成环与移动后超过三级的子树一律拒绝，删除有知识的分类要 `force=true`（知识变未分类）。 - 知识列表支持 `category_id`（含子树）、`uncategorized`、`tag`；输出带 `category`（含 `path` / `full_path`）。 - PATCH 只改分类或标签也会推进 `version`，避免"只动标签"之后下次保存撞乐观锁 `4009`。 Web - `Sheet` 增 `size="md/lg/xl"` 与展开整屏按钮；任务、工单、知识抽屉统一加宽（`TaskDetail` / `Tickets` / `Knowledge`）。 - 知识页：左侧三级分类树（新建、按子树筛选、未分类）、`KnowledgeComposer` 一次写全新的备忘录、列表卡片露出分类路径与标签、详情抽屉里可直接改分类与标签。 - 抽屉详情只拉一次：重复的 effect 或迟到的响应不再覆盖用户正在敲的内容。安卓 - `Api.kt`：分类模型与接口、新建/更新带 `tag_names`/`category_id`、列表带分类与标签筛选。 - 知识页重做：新建改为近全屏大对话框（标题/类型/分类/标签/正文），列表顶部按分类筛选，详情里能改分类与标签后单独保存。文档与测试 - `2.Design/API.md`：5.1/5.3/5.4 补分类与筛选参数，新增 5.5 分类接口章节，错误码补 `7006`/`7007`/`7008`。 - `2.Design/ROADMAP-M0-M1.md`：新增 3.11（三级分类）、3.12（备忘录形态）。 - 新增 `backend/tests/test_knowledge_categories.py`（8 例）：备忘形态落库、三级到底、移动越界与成环、重名、按子树/未分类/标签/关键词筛选、删分类需 `force`、跨租户隔离。 - 新增 `web/e2e/knowledge-notebook.mjs`（10 项，全绿）：建两级分类 → 一次写全 → 卡片与筛选 → 抽屉改标签/分类 → 正文落库 → 重名 7008。验证：`pytest` 93 passed、`ruff check` / `ruff format --check` 全过、 `tsc --noEmit` 通过、`vite build` 通过、`knowledge-notebook.mjs` 10 项全绿。安卓端本机只有 JDK 25，Gradle 8.7 / AGP 8.7.3 不支持，本次未做编译验证。	2026-10-30 03:51:43 +08:00
Steven	91b3dde670	feat(notify): 站内通知与手工开单，指派/改状态/评论/验收都有人收到 CI / backend (push) Canceled after 0s Details M2 最后一块：让"该我办了"能出现在系统里，并且允许不经过任务直接开单。通知（backend/app/services/notify.py 统一出口） - 七类触发：task_assigned、task_status_changed、item_commented、 ticket_assigned、ticket_submitted、ticket_approved/rejected、task_unblocked - 不通知自己：notify() 按 actor_id 跳过，调用方不用各自判断 - 已读：GET /notifications、/unread-count、POST /read、/read-all 手工开单 - POST /tickets：直接指定人、初始 open，与任务升级单共用同一条 kind='ticket' item， ticket_ext.parent_item_id 为空，验收通过不回流任务 - 指派前 _ensure_member 校验在册成员，越界指派返回 1001（避免"挂在看不到的名字上"）前端 - Web：通知页 /w/:wsId/notifications（未读/全部，点开标已读并跳目标）；工单页"新建"面板；AppShell 每 30 秒对未读数，标已读后 dispatch notifications:changed 立刻刷新；任务与工单支持 ?open= 深链落地即展开 - 安卓：五个 tab 加"通知"，未读数 30 秒刷新；工单动作按需求人/办理人/管理员显隐；手工开单对话框验证 - pytest 85 passed（新增 backend/tests/test_notifications.py 6 个用例） - ruff check / format --check 全 0 - tsc --noEmit 通过；vite build 成功 - web/e2e/notifications.mjs 12 项断言全绿（手工开单 → B 收到 → 点开跳转 → 未读归零） - 安卓：本机 JDK 25 与 Gradle 8.7 / AGP 8.7.3 不兼容，本次未做编译验证，装回 JDK 17 后第一件事是 assembleDebug	2026-10-30 02:19:42 +08:00
