fix(ci): 存量历史提交只告警不拦截，新增提交仍严格校验

把早已推送到其它远端分支的 lineage 合进 main 时，被带进来的提交不是本次新增，
它们标题不合规属既有事实。闸门先抓全部远端分支头，用 git branch -r --contains
取证：能证明已存在于其它远端分支的只告警放行；证不出来的照旧拦截（fail-closed）。

-# DobotAI Platform
+# DobotAI 平台
 
-DobotAI is the external enterprise integration layer for official WeKnora. It does not import WeKnora packages, modify WeKnora source, or access the WeKnora database.
+DobotAI 是 WeKnora 的企业外部渠道集成层，负责钉钉协议、身份与会话映射、消息编排、流式卡片、媒体收发、覆盖判定和人工支持通知。它只通过 WeKnora 官方 REST/SSE API 调用知识问答与 Agent Chat：不导入 WeKnora 私有包、不修改 WeKnora 源码，也不访问 WeKnora 数据库。
 
-Current milestone: channel-bound Agent QA core.
+## 当前能力
 
-Implemented:
+- 通过官方 `POST /api/v1/sessions` 与 `POST /api/v1/agent-chat/:session_id` 调用 WeKnora；
+- 严格解析 SSE 的 `answer`、`references`、`tool_call`、`tool_result`、`error` 与终止事件；`error + done=false` 被视为可恢复的工具错误，不会提前结束钉钉卡片；
+- 解析普通引用及智能推理工具结果中的检索证据，供覆盖判定与后端审计使用；
+- 按渠道、会话和用户维护长期 WeKnora Session，并保证回调幂等；
+- 钉钉 Stream 机器人支持文本、richText 以及多图片输入；图片下载经过钉钉官方接口、大小与文件签名校验后，才以 WeKnora 通用多模态请求发送；
+- 钉钉 AI 流式卡片与最终消息回退；通道侧保留原始回答，不修改 WeKnora 持久化消息；
+- 默认快速问答，支持 `/think <问题>` 单次推理、`/think on` 持续推理、`/think off` 或 `/rag` 关闭推理；快速问答与智能推理共用同一 WeKnora Session；
+- 用户级推理轮次、空闲到期、提示开关和首次使用指引；
+- 成功回答的覆盖判定、持久化 Support Case、FAQ Outbox 与钉钉人工支持群通知；
+- 对已覆盖答案点踩时创建 `feedback_down` 人工处理提醒；对已先因未覆盖创建 Case 的同一问题保持“一题一个 Case”幂等；
+- 可选的钉钉问题表异步写入；写入失败不会改变问答成功状态；
+- 可选的回答图片外发：仅将 WeKnora `resource://` 图片通过鉴权下载、内容哈希转存到私有 OSS 后，以受控 HTTPS 地址提供给钉钉。
 
-- official `POST /api/v1/sessions` adapter;
-- official `POST /api/v1/agent-chat/:session_id` adapter;
-- fail-closed SSE parsing for `references`, `answer`, `error`, and terminal `done`;
-- per-channel/per-conversation Agent binding;
-- long-lived direct-user sessions;
-- shared-group sessions, with optional group+user policy;
-- external-message idempotency;
-- independent PostgreSQL session/turn storage;
-- authenticated internal `POST /v1/qa` ingress endpoint.
-- unauthenticated read-only `GET /version` runtime build identity endpoint.
-- DingTalk Stream text ingress (official SDK) wired into `cmd/dobotai`.
-- v1 knowledge coverage decisions, durable support cases, and optional DingTalk support-group notifications.

-- Uses the official DingTalk Stream SDK (`dingtalk-stream-sdk-go`); no public webhook endpoint is exposed.
-- Text messages only for now. Images, OpenAPI fallback, and card replies are not implemented yet.
-- Group chats are handled only when the bot is @-mentioned; other group messages are ignored.
-- Sessions: direct chats use one long-lived session per user; group chats share one session per group (default `shared` policy).
-- Replies are sent via the callback's `sessionWebhook`, which is fail-closed: only `https` URLs on `*.dingtalk.com` (port 443, no redirects) are accepted.
-- Required env vars to enable (all three or none): `DINGTALK_CLIENT_ID`, `DINGTALK_CLIENT_SECRET`, `DOBOTAI_TENANT_KEY`. Partial configuration is a fatal startup error.
-- Optional `DINGTALK_SUPPORT_GROUP_OPEN_CONVERSATION_ID` enables durable uncovered-answer ActionCard notifications through the official group-message API. It requires the FAQ table workflow below so every “去回答” button targets an exact record. When empty, coverage decisions and support cases are still recorded but no group message is sent.
+责任边界：
 
-## DingTalk question table sync (Notable v1)
+- **DobotAI**：钉钉协议、媒体收发、会话映射、命令路由、卡片、覆盖判定、人工支持、渠道审计。
+- **WeKnora**：通用 Agent Chat、检索、知识存储、引用与模型调用。
+- **DobotAI PostgreSQL**：只保存渠道与业务编排数据，不保存 WeKnora 知识正文。
+- **Redis**：仅用于队列、重试、幂等租约和短期状态。
 
-Successful DingTalk QA turns can be appended asynchronously to a DingTalk Notable AI table through a durable PostgreSQL outbox. Notable failures never change the successful QA result; the worker retries with bounded backoff and stores only stable failure codes.
+## 目录结构
 
-Apply `db/migrations/000010_question_table_exports.up.sql` before enabling the worker. The three table settings are optional as a group: all blank disables dispatch, while a partial configuration fails startup closed.

-- `DINGTALK_QUESTION_TABLE_BASE_ID`

+目录职责规则：`cmd/`只装配进程，`internal/`承载业务模块，`internal/store/postgres/`只实现数据库持久化，`db/migrations/`只放Schema变更，`deploy/`只放容器运行资产。历史计划、备份、镜像归档和真实环境文件均不进入Git。
 
-The worker reuses `DINGTALK_CLIENT_ID` and `DINGTALK_CLIENT_SECRET`. The DingTalk application must have `Notable.Base.Read.All` and `Notable.Base.Write.All`. Only successful `channel=dingtalk` turns are enqueued; other channels are excluded. The first release writes the nine basic text/date/user fields and omits the five select-classification fields.
+## 部署方式
 
-## Uncovered-question FAQ workflow
+| 方式 | 适用场景 | 数据库 | 入口 |
+| --- | --- | --- | --- |
+| 源码/原生二进制 | 本地开发、快速调试 | 手工配置阿里云RDS连接 | `go run ./cmd/dobotai` |
+| Docker | 测试、预发布、生产候选 | 既有阿里云RDS；Docker不运行数据库 | `sudo bash ./install-docker.sh` |
 
-Apply `db/migrations/000011_faq_exports.up.sql` before enabling this workflow. Existing support cases are marked `not_applicable` and are not backfilled; only support cases created after the migration default to `pending` FAQ export.
+### 源码部署
 
-Set all four values together, or leave all four blank to disable FAQ export. Partial configuration fails startup closed:
+```bash
+go run ./cmd/dobotai
+curl --noproxy '*' -fsS http://127.0.0.1:8090/healthz
+```
 
-- `DINGTALK_FAQ_TABLE_BASE_ID`
-- `DINGTALK_FAQ_TABLE_SHEET_ID`
-- `DINGTALK_FAQ_TABLE_VIEW_ID`
-- `DINGTALK_FAQ_TABLE_OPERATOR_ID` (DingTalk unionId)
+源码方式不自动安装Docker、不创建目录、不检查RDS表，也不适合作为长期渠道消费者。
 
-For every newly detected uncovered answer, the asynchronous worker creates one FAQ record with standard question, original question, detected language, and asker. After DingTalk returns the `recordId`, DobotAI stores it and sends a built-in `sampleActionCard` containing only the current question and up to five earlier questions from the same stable actor. The “去回答” button opens that exact FAQ record. FAQ insert failures are retried with bounded backoff and never block the customer reply.
+### Docker + 阿里云RDS部署
 
-## WeKnora baseline
+克隆仓库后在根目录执行：
 
-Target policy: latest stable official Release/Tag. The newest locally fetched stable tag is `v0.6.3`. Online GitHub verification is pending because DNS/proxy access was unavailable during initialization.
+```bash
+sudo bash ./install-docker.sh
+sudo dobotai-dingtalk-configure
+```
 
-## Run
+第一条命令自动安装Docker/Compose（如缺失）、构建应用镜像、准备目录和配置模板；第二条命令安全录入RDS、WeKnora与钉钉配置，然后检查RDS表：空库初始化`000001`至`000021`，完整表不写入，异常/半成品表拒绝启动。Docker只运行`dobotai-dingtalk`，不创建`dobotai-postgres`、本地数据卷或本地数据库。
 
-1. Create an independent PostgreSQL database named `dobotai`.
-2. Apply `db/migrations/000001_core.up.sql` to that database only.
-3. Copy `.env.example` to a local `.env` and supply secrets outside Git.
-4. Export the variables and run:
+完整安装、RDS检查、升级和回滚见 [Docker部署手册](deploy/dobotai-dingtalk/README.md)。
+
+## 钉钉 Stream
+
+使用官方 `dingtalk-stream-sdk-go`，不暴露公网回调入口。
+
+- 群聊仅在机器人被 `@` 时处理；
+- 私聊按用户保持长期会话；群聊默认按群共享会话；
+- 回调 `sessionWebhook` 严格限制为 `https`、`*.dingtalk.com`、443端口且不允许重定向；
+- 启用 Stream 必须同时设置以下三项；三者均为空时渠道禁用，部分配置会失败关闭：
+
+```text
+DINGTALK_CLIENT_ID
+DINGTALK_CLIENT_SECRET
+DOBOTAI_TENANT_KEY
+```
+
+## 推理模式命令
+
+```text
+/think <问题>            仅当前问题使用智能推理
+/think on                开启持续智能推理
+/think off 或 /rag       关闭持续智能推理
+/setting rounds <1-50>   设置持续推理自动关闭轮数
+/setting hint <on|off>   设置剩余轮次提示
+/help、/帮助、/h          查看当前模式和帮助
+```
+
+持续推理默认最多10轮，成功回答才消耗轮次；10分钟无交互后逻辑到期，下一次问题自动回到快速问答。状态按 `tenant + channel + external_actor_id` 隔离。
+
+## 首位管理员终端绑定
+
+首位管理员不通过网页生成验证码。先确保钉钉 Stream 机器人已经正常运行，登录部署服务器后执行：
+
+```bash
+dobotai bootstrap-admin
+```
+
+若二进制未加入 `PATH`，使用其实际绝对路径执行。该命令只读取 `DATABASE_URL` 和 `DOBOTAI_TENANT_KEY`，不会启动 WeKnora、钉钉消费者或问答服务。
+
+命令会在终端使用加密随机数生成一个有效期10分钟的六码绑定码，并保持等待。候选管理员必须私聊机器人发送：
+
+```text
+/setting <六码绑定码>
+```
+
+验证码正确后，终端自动将该钉钉用户绑定为 `super_admin` 并显示成功。已有有效管理员时命令会拒绝执行，防止通过该入口追加或替换管理员。DobotAI 不提供网页管理面；钉钉凭据和运行配置由部署环境文件管理。
+
+## 覆盖与人工支持
+
+- 有结构化检索引用的回答标记为已覆盖；
+- 没有引用但已执行检索的回答标记为未覆盖；
+- 没有引用且未执行检索的文本标记为 `covered_non_knowledge_response`，不创建 Support Case；
+- 纯图片视觉识别单独记录为 `covered_visual_recognition`，不计入“未覆盖”；
+- 无权威知识时，产品统一回复：`当前暂无已发布的权威知识，暂不建议操作。`；
+- 人工通知只带当前问题和同一用户此前最多5个问题，不包含回答、引用或置信度；
+- 未覆盖与点踩共用幂等 Support Case，避免对同一 Turn 重复通知。
+
+## 配置
+
+复制 `.env.example` 为仅本机可读的运行时环境文件，并在 Git 外注入真实值。不得提交 API Key、数据库密码、钉钉凭据、OSS AccessKey、预签名 URL 或真实用户/群组标识。
+
+关键配置：
+
+```text
+DOBOTAI_LISTEN_ADDR
+DOBOTAI_INGRESS_TOKEN
+DOBOTAI_AGENT_BINDINGS
+DOBOTAI_QUICK_AGENT_ID
+DOBOTAI_REASONING_AGENT_ID
+WEKNORA_BASE_URL
+WEKNORA_API_KEY
+DATABASE_URL
+```
+
+可选能力必须整组配置或整组留空：
+
+- 钉钉 Stream；
+- 钉钉 AI 卡片；
+- 未覆盖问题 FAQ 表；
+- 人工支持群通知；
+- 问题表异步写入；
+- 回答图片私有 OSS 外发。
+
+任何部分配置均应在启动时失败关闭，而不是以不完整权限运行。
+
+## 数据库迁移
+
+DobotAI 使用独立 PostgreSQL，禁止指向 WeKnora 数据库。生产部署前必须按版本顺序执行并演练 `db/migrations/` 中的迁移；当前发布范围包含：
+
+```text
+000001_core ... 000018_coverage_visual_recognition_reason
+000019_reasoning_mode_state
+000020_feedback_support_trigger
+000021_coverage_non_knowledge_response_reason
+```
+
+迁移前应执行逻辑备份并验证恢复；迁移、二进制部署和钉钉渠道切换是独立步骤，不能把健康检查代替真实渠道验收。
+
+## 本地运行
 
 ```bash
 go run ./cmd/dobotai
 ```
 
-Health check:
+健康检查：
 
 ```bash
 curl http://127.0.0.1:8090/healthz
 ```
 
-Runtime version check:
+运行版本：
 
 ```bash
 curl http://127.0.0.1:8090/version
 ```
 
-`scripts/deploy-local.sh` builds from its own worktree (or the explicit
-`DOBOTAI_SOURCE_ROOT`), injects `version`, `commit_sha`, and `build_time`, and
-accepts the deployment only when `/version` reports the exact source commit.
-It refuses dirty worktrees so the reported SHA cannot hide uncommitted source.
+部署脚本应将 `version`、`commit_sha` 和 `build_time` 写入二进制，并仅在 `/version` 返回预期提交时接受部署。候选源码必须干净，避免运行版本掩盖未提交改动。
 
-Internal QA request:
+## 安全要求
 
-```bash
-curl -X POST http://127.0.0.1:8090/v1/qa \
-  -H "Authorization: Bearer $DOBOTAI_INGRESS_TOKEN" \
-  -H 'Content-Type: application/json' \
-  -d '{

-    "external_user_id":"user-1",
-    "external_message_id":"message-1",
-    "query":"hello"
-  }'
-```
+- 不修改 WeKnora 源码、Schema 或私有包；
+- 不直接连接 WeKnora 数据库；
+- 不将凭据、Token、预签名 URL 或知识正文写入日志；
+- 不接受任意外部图片 URL 作为可信媒体；
+- 对钉钉图片、WeKnora `resource://` 图片和 OSS 返回体均执行来源、大小、类型和签名校验；
+- 外发 OSS Bucket 保持私有；
+- 生产、测试的钉钉应用、数据库、OSS Bucket 和凭据必须相互隔离；
+- 生产上线必须使用已验收的同一构建产物，禁止在生产重新编译。

-- No WeKnora source modifications.
-- No custom WeKnora tables or columns.
-- No direct WeKnora database access.
-- No private WeKnora package imports.
-- All compatibility logic stays in `internal/weknora`.

+# DobotAI Docker部署（阿里云RDS）
+
+## 定位
+
+DobotAI是钉钉渠道编排与交付服务。Docker只运行应用容器`dobotai-dingtalk`；数据库唯一使用已有的阿里云RDS PostgreSQL。
+
+```text
+钉钉 Stream
+   ↓
+dobotai-dingtalk 容器
+   ├─ 阿里云RDS PostgreSQL：Turn、会话、反馈、管理员、覆盖判定
+   └─ 既有WeKnora：Agent、检索、知识、模型
+```
+
+禁止创建或使用：
+
+```text
+dobotai-postgres 容器
+dobotai-postgres-data 数据卷
+本地PostgreSQL作为DobotAI目标数据库
+```
+
+## 架构与目录
+
+```text
+宿主机
+├── dobotai-dingtalk                 唯一应用容器，host网络
+├── /opt/dobotai/container/          Compose、RDS检查器、SQL迁移、启动脚本
+├── /opt/dobotai/config/dobotai.env  0600，RDS/WeKnora/钉钉配置
+├── /opt/dobotai/secrets/            0700，DobotAI SecretStore
+└── /opt/dobotai/backups/            发布前RDS备份记录，不保存Docker数据库卷
+
+阿里云RDS
+└── DobotAI专用PostgreSQL数据库
+```
+
+应用使用`network_mode: host`，因此通过RDS私网地址访问云数据库、通过`127.0.0.1:8080`访问宿主机现有WeKnora。不会开放新的数据库端口；应用HTTP仍由`DOBOTAI_LISTEN_ADDR=127.0.0.1:8090`约束。
+
+## 安装
+
+克隆完整仓库后，只执行：
+
+```bash
+sudo bash ./install-docker.sh
+```
+
+根脚本自动：
+
+```text
+检查或安装Docker Engine和Docker Compose v2（APT系统）
+以当前Git提交构建 dobotai-dingtalk:local-<Git短SHA>
+创建 /opt/dobotai/{container,config,secrets,backups}
+复制应用Compose、RDS检查器和21个SQL迁移
+生成权限0600的应用环境模板
+安装三条短命令
+```
+
+它不会连接、创建或修改RDS，也不会启动未配置的钉钉应用。
+
+## 配置、RDS检查与启动
+
+安装后执行：
+
+```bash
+sudo dobotai-dingtalk-configure
+```
+
+配置器分字段录入阿里云RDS（主机、端口、数据库名、账号、密码），自动组装连接串；WeKnora和钉钉凭证密钥不回显，环境文件原子写入且权限0600。
+
+`DOBOTAI_TENANT_KEY`不是WeKnora Agent租户键。它是DobotAI内部数据隔离键，首次安装时自动生成并固定保存；配置器不会要求填写或改动它。WeKnora侧只需要填写实际的两个Agent ID。
+
+配置器会要求两个不同的WeKnora Agent ID，并自动生成`DOBOTAI_AGENT_BINDINGS={"dingtalk:*":"快速问答Agent ID"}`。`DOBOTAI_INGRESS_TOKEN`是保护本机`POST /v1/qa`内部接口的Bearer Token，不用于钉钉或WeKnora；同样由安装器自动生成。
+
+| 配置 | 示例 | 作用 |
+| --- | --- | --- |
+| `DATABASE_URL` | `postgres://USER:***@rds-endpoint:5432/dobotai?sslmode=require` | DobotAI专用阿里云RDS PostgreSQL |
+| `WEKNORA_BASE_URL` | `http://127.0.0.1:8080` | 宿主机既有WeKnora |
+| `WEKNORA_API_KEY` | `<你的WeKnora API Key>` | DobotAI专用Key |
+| `DOBOTAI_QUICK_AGENT_ID` | `<快速问答Agent ID>` | 默认快速问答实际调用的Agent |
+| `DOBOTAI_REASONING_AGENT_ID` | `<智能推理Agent ID>` | `/think`和持续智能推理实际调用的Agent |
+| `DINGTALK_CLIENT_ID` | `dingxxxxxxxx` | 钉钉AppKey |
+| `DINGTALK_CLIENT_SECRET` | `<你的钉钉 AppSecret>` | 钉钉AppSecret |
+
+回答图片外发OSS同为分字段录入的可选整组（紧随RDS之后、WeKnora/钉钉凭证之前）：
+
+| 配置 | 示例 | 作用 |
+| --- | --- | --- |
+| `DOBOTAI_OUTBOUND_IMAGE_OSS_ENDPOINT` | `https://oss-cn-shenzhen.aliyuncs.com` | 私有Bucket接入地址 |
+| `DOBOTAI_OUTBOUND_IMAGE_OSS_REGION` | `cn-shenzhen` | Bucket所在地域 |
+| `DOBOTAI_OUTBOUND_IMAGE_OSS_BUCKET` | `dobot-xxx` | 外发图片专用私有Bucket |
+| `DOBOTAI_OUTBOUND_IMAGE_OSS_ACCESS_KEY_ID` | `<AK ID>` | 仅授权该Bucket的AK |
+| `DOBOTAI_OUTBOUND_IMAGE_OSS_ACCESS_KEY_SECRET` | `<AK Secret>` | 仅授权该Bucket的SK（不回显） |
+| `DOBOTAI_OUTBOUND_IMAGE_PUBLIC_BASE_URL` | `https://host/dingtalk/i` | 钉钉可见的稳定HTTPS入口，不含凭据 |
+
+OSS规则：六项全部留空即整组禁用图片外发（答案含`resource://`图片时按无图降级）；填写任一项则六项必填，缺项拒绝保存。运行时仅改写WeKnora `resource://`引用为短签HTTPS，私有Bucket由稳定基础地址代理，`<img>`外链与`data:`剥除。禁止把OSS凭据写入Git或命令行。
+
+保存后脚本自动执行以下RDS门禁：
+
+```text
+1. 使用RDS连接串执行 pg_isready
+2. 检查DobotAI核心表
+3. 数据库没有任何public表：按000001~000021初始化
+4. 所有核心表存在：判定正常，不执行任何DDL
+5. 部分表、缺表或非空异常库：拒绝初始化和启动
+6. RDS通过后才启动 dobotai-dingtalk 并检查 /healthz
+```
+
+这保证不会把已有RDS表误当成空库重建，也不会把半成品或错误库静默升级。
+
+## 日常命令
+
+```bash
+# 重新检查RDS并启动/升级应用
+sudo dobotai-dingtalk-start
+
+# 交互更新RDS、WeKnora、钉钉配置后启动
+sudo dobotai-dingtalk-configure
+
+# 仅首位管理员且无有效管理员时使用
+sudo dobotai-dingtalk-bind-admin
+
+# 健康与版本
+curl --noproxy '*' -fsS http://127.0.0.1:8090/healthz
+curl --noproxy '*' -fsS http://127.0.0.1:8090/version
+```
+
+## 升级与回滚
+
+应用升级仅替换`dobotai-dingtalk`镜像。启动前再次检查RDS；健康失败时恢复上一应用镜像（如存在）。RDS不是容器资产，不能被`docker compose down`、镜像替换或本机卷操作影响。
+
+RDS有实际数据时，数据库备份、SQL变更与恢复应在阿里云RDS发布流程中完成并验证；不要把应用镜像回滚误当成数据库回滚。
+
+## 首位管理员
+
+应用和钉钉Stream运行后：
+
+```bash
+sudo dobotai-dingtalk-bind-admin
+```
+
+终端会显示10分钟有效的六码；候选管理员私聊机器人：
+
+```text
+/setting <六码绑定码>
+```
+
+已有有效管理员时绑定命令会拒绝，避免提权。
+
+## 不执行的操作
+
+```text
+不创建本地PostgreSQL容器或数据卷
+不迁移、删除或覆盖现有本地 dobotai-test-postgres
+不创建、删除或重置阿里云RDS数据库
+不把RDS连接串、Token、钉钉凭据写入Git、命令行或日志
+不重建WeKnora、Neo4j、Redis、Elasticsearch
+```

 |---|---|
-| Like/dislike and unresolved reason | DobotAI PostgreSQL and API |
-| Formal covered/not-covered decision | DobotAI evaluation rules using references, scores, answer status, and offline calibration |
-| Support case, owner, SLA, and status | DobotAI workflow |
-| Human reply to original channel | DobotAI channel adapter; not written to WeKnora history by default |
-| Stable external turn correlation | DobotAI mapping of external message, turn, WeKnora session/request, and gateway trace |
-| Complete multi-call token usage | Model gateway/Langfuse; unknown remains null/unknown |
-| Strict image failure semantics | Adapter contract test; reject image traffic on failure |
-| Arbitrary human assistant-message append | Keep in DobotAI and submit an upstream API request only if context injection becomes necessary |
+| 点赞、点踩和未解决原因 | DobotAI PostgreSQL 与 API |
+| 正式的已覆盖/未覆盖判定 | DobotAI 基于引用、分数、回答状态和离线校准的评估规则 |
+| Support Case、负责人、SLA 和状态 | DobotAI 工作流 |
+| 向原始渠道发送人工回复 | DobotAI 渠道适配器；默认不写回 WeKnora 历史 |
+| 稳定的外部 Turn 关联 | DobotAI 映射外部消息、Turn、WeKnora 会话/请求和网关追踪 |
+| 完整的多调用 Token 用量 | 模型网关/Langfuse；未知值保持 `null/unknown` |
+| 严格的图片失败语义 | Adapter 契约测试；图片流量失败时拒绝处理 |
+| 任意人工助手消息追加 | 保留在 DobotAI；仅当确有上下文注入需求时向上游提交 API 请求 |

-DobotAI PostgreSQL owns channel identities, external messages, session mappings, turns, feedback, coverage decisions, support cases, human replies, FAQ workflow state, and content-source mappings. WeKnora owns only its official data model.
+DobotAI PostgreSQL 负责渠道身份、外部消息、会话映射、Turn、反馈、覆盖判定、Support Case、人工回复、FAQ 工作流状态和内容源映射。WeKnora 仅负责其官方数据模型。
 
-## Session policy
+## 会话策略
 
-Default policy:
+默认策略：
 
-- direct: one long-lived session per tenant + channel + Agent + external user;
-- group: one shared session per tenant + channel + Agent + external group;
-- group messages are admitted only when the bot is mentioned or an explicit command triggers it;
-- sender display name is prefixed to the query so a shared Agent can distinguish speakers;
-- future controls must include idle rotation and an explicit new-conversation command;
-- confidential channels may switch to `per_user`, yielding group + user sessions.
+- 私聊：每个 `tenant + channel + Agent + 外部用户` 使用一个长期会话；
+- 群聊：每个 `tenant + channel + Agent + 外部群` 使用一个共享会话；
+- 群消息仅在机器人被提及或命中显式命令时进入处理；
+- 将发送人显示名添加到问题前缀，使共享 Agent 能区分发言者；
+- 后续控制项必须包含空闲轮换和显式新建会话命令；
+- 保密渠道可切换为 `per_user`，形成群组加用户维度的会话。
 
-Shared group sessions are the common collaboration-bot pattern because all members see the same conversation. Group+user sessions provide stronger context isolation but make replies less coherent for collaborative group discussions.
+共享群会话符合协作机器人场景：所有成员能看到相同上下文。群组加用户会话能增强上下文隔离，但会削弱协作讨论中的回复连贯性。
 
-## Agent binding
+快速问答与智能推理必须复用同一个 WeKnora Session；`/think` 仅改变当前 Turn 的执行 Agent，不得重建会话映射。
 
-Agents are configuration-owned. Channel callers cannot choose an arbitrary `agent_id`.
+## Agent 绑定
 
-Resolution order:
+Agent 由配置控制，渠道调用方不得任意指定 `agent_id`。
 
-1. exact `<channel>:<external_chat_id>` binding;
-2. channel wildcard `<channel>:*`;
-3. fail closed when no binding exists.
+解析顺序：
 
-## Image failure policy
+1. 精确 `<channel>:<external_chat_id>` 绑定；
+2. 渠道通配 `<channel>:*`；
+3. 没有任何绑定时失败关闭。
 
-Before enabling image traffic, the WeKnora Adapter must run a contract test against the selected official release and configured vision model.
+## 首位管理员终端绑定
 
-If any image path fails:
+首位管理员绑定由部署服务器终端发起，而非网页发码。钉钉 Stream 机器人已正常运行且当前不存在有效管理员时，操作人员执行：
 
-1. do not resend the question without the image;
-2. do not return partial model output as success;
-3. return a typed `vision_unavailable` failure to the channel adapter;
-4. DingTalk tells the user that image recognition is temporarily unavailable and asks them to retry or send text;
-5. emit an operational alert to verify Agent image upload settings, selected vision model, provider connectivity, and model capability;
-6. keep image traffic disabled until the contract test passes.
+```bash
+dobotai bootstrap-admin
+```
 
-No WeKnora source patch is allowed as a workaround.
+命令只连接 DobotAI PostgreSQL，使用加密随机数创建一个有效期10分钟、最多5次错误尝试的六码挑战，并在终端持续等待。候选用户必须私聊机器人发送：
 
-## Service ownership
+```text
+/setting <六码绑定码>
+```
 
-- `internal/weknora`: official REST/SSE compatibility only.
-- `internal/qa`: business orchestration and terminal-state ownership.
-- `internal/session`: external-to-WeKnora session policy.
-- `internal/store/postgres`: DobotAI business persistence only.
-- `internal/coverage`: v1 covered/uncovered evaluation, durable support-case dispatch, finite retries, and stable failure codes. Notification failures never change a successful QA result.
-- `internal/channels/dingtalk`: DingTalk Stream ingress (official SDK), text-only robot callbacks, fail-closed session webhook replies (`https`, `*.dingtalk.com`, no redirects). Wired in `cmd/dobotai`; enabled only when `DINGTALK_CLIENT_ID`, `DINGTALK_CLIENT_SECRET`, and `DOBOTAI_TENANT_KEY` are all set. Group messages require an @-mention; direct chats map to one long-lived session per user, groups to one shared session per group. Images, OpenAPI fallback, and card replies are not implemented yet.
-- future `channels/*`: platform callbacks and outbound replies.
-- future `content-sync/*`: DingTalk KB, NAS, and CMS synchronization.
-- model gateway: token accounting, routing, quotas, circuit breaking, and provider observability.
-- Redis: queue, retry, short leases, and temporary stream state only.
+验证码匹配后，渠道侧只记录候选身份；终端轮询并事务性将该候选用户写为 `super_admin/active`，然后显示成功并退出。已有有效管理员时该命令拒绝执行，避免任意用户通过终端绑定流程被提权。DobotAI 不提供网页管理面，钉钉凭据和运行配置由部署环境文件管理。
 
-## Upgrade contract
+## 图片失败策略
 
-For every official WeKnora upgrade:
+启用图片流量前，WeKnora Adapter 必须针对选定的官方版本和视觉模型执行契约测试。
 
-1. update the pinned official release/tag;
-2. run official database migrations against WeKnora only;
-3. run DobotAI Adapter contract tests;
-4. verify text Agent Chat, references, terminal errors, Stop, images, ingestion, and FAQ;
-5. promote the official image only after the contract suite passes.
+任一图片路径失败时：
+
+1. 不得去掉图片后重发同一问题；
+2. 不得将部分模型输出当作成功结果；
+3. 向渠道适配器返回类型化 `vision_unavailable` 错误；
+4. 钉钉提示用户图片识别暂不可用，并请其重试或发送文本；
+5. 发送运维告警，核查 Agent 图片上传设置、视觉模型、供应商连通性和模型能力；
+6. 契约测试通过前保持图片流量禁用。
+
+不得通过修改 WeKnora 源码规避上述失败。
+
+对钉钉 richText 中的图片，DobotAI 仅通过官方接口下载，验证来源、大小、媒体类型和文件签名后，才转换为 WeKnora 通用多模态请求。对回答中的 `resource://` 图片，仅可在鉴权获取、内容哈希转存私有 OSS 后外发；不得把任意外部 URL 当作可信图片。
+
+## 服务职责
+
+- `internal/weknora`：仅处理 WeKnora 官方 REST/SSE 兼容；解析普通引用和智能推理工具结果引用；
+- `internal/qa`：业务编排与 Turn 终态归属；
+- `internal/session`：外部渠道到 WeKnora 的会话策略；
+- `internal/store/postgres`：仅保存 DobotAI 业务数据；
+- `internal/coverage`：已覆盖/未覆盖/纯视觉识别判定、持久化 Support Case、有限重试和稳定错误码；通知失败不得改变成功问答的结果；
+- `internal/channels/dingtalk`：钉钉 Stream 接入、richText 与多图片归一化、AI 流式卡片、命令路由、反馈与通知。仅在 `DINGTALK_CLIENT_ID`、`DINGTALK_CLIENT_SECRET` 和 `DOBOTAI_TENANT_KEY` 均已设置时启用。群聊必须 `@` 机器人；私聊按用户映射长期会话，群聊默认映射共享会话；`sessionWebhook` 必须是 `https`、`*.dingtalk.com`、443端口且不允许重定向；
+- `internal/reasoningmode`：`/think` 单次与持续推理、轮数、空闲到期、提示和首次使用引导；
+- `internal/outboundimage`：WeKnora `resource://` 图片的受控鉴权下载和私有 OSS 外发；
+- `future channels/*`：其他平台的回调与外发回复；
+- `future content-sync/*`：钉钉知识库、NAS 与 CMS 同步；
+- 模型网关：Token 统计、路由、配额、熔断和供应商可观测性；
+- Redis：仅用于队列、重试、短期租约和临时流状态。
+
+## 升级契约
+
+每次升级官方 WeKnora 时：
+
+1. 更新固定的官方 Release/Tag；
+2. 仅对 WeKnora 执行官方数据库迁移；
+3. 执行 DobotAI Adapter 契约测试；
+4. 验证文本 Agent Chat、引用、终止错误、停止、图片、导入和 FAQ；
+5. 仅在契约测试通过后推广官方镜像。
+
+WeKnora 升级、DobotAI 迁移、钉钉单消费者切换和生产部署是独立变更边界，必须各自备份、演练和验收。
