-# AGENTS.md — deep_agent 2.0 工程纪律
-
-本文件是给**在本仓库里干活的人和 AI 助手**看的硬约束。改代码前先读这里；
-与这里冲突的改动，要么别做，要么先改这里并说明理由。
-
----
-
-## 〇、项目定位
-
-2.0 是通风智能体系统的**新一代骨架**，参照 1.5 的对外契约重建，但内部实现
-不做移植。定位是「可运行的骨架」，不是「功能完备的产品」：
-
-- **对外契约完全兼容 1.5**（`POST /api/chat` 的 multipart 入参与 SSE 帧格式），
-  这样 1.5 的前端不改一行就能连上。
-- **对内一切重写**。1.5 积累的 40 个业务工具、22 个业务技能、MCP 工具池、
-  计费/调度/子智能体管理页都**不在**本仓库范围内。
-- 骨架的价值在于**结构与纪律**，不在于功能数量。
-
----
-
-## 一、五条不变式（改动前必读）
-
-### 1. `thread_id ≡ session_id`
-
-由 `api/chat_routes._init_session` 强制。客户端传别的值一律 404。
-
-理由：checkpointer 是进程级共享的，允许客户端指定任意 thread_id 就等于
-允许读写别人的图状态。这条不变式在 2.0 是**全局**的——包括定时任务
-（它为自己的每次执行建独立会话，而不是另起一个 thread_id 命名法）。
-
-### 2. 单进程（`workers=1`）
-
-三处进程内状态：SQLite checkpointer、并发闸计数、APScheduler。
-多 worker 下它们各自独立，症状是「同一会话续跑读不到上文的图状态」、
-「并发闸形同虚设」、「定时任务被每个 worker 各触发一次」。
-
-`main._check_single_process()` 会检测并告警。要扩多进程，先把这三处
-换成 Redis/MySQL，别只改启动参数。
-
-### 3. 计费口径以 provider 的真实 usage 为准
-
-`api/context_meter.extract_usage` 优先读 `usage_metadata`，读不到才回落本地
-估算，并把 `usage_source` 标成 `estimate`。
-
-**不要改成本地估算优先**。1.5 就是估算优先，为此专门开了
-`fix/context-usage-accounting` 分支修口径；估算值参与决策的代价是
-「限额拦不住、账单对不上」，而且没人能一眼看出哪些数字是估的。
-
-### 4. 来源标注由工具侧产出，不靠模型自觉
-
-工具用 `tools.registry.sourced(data=..., sources=[...])` 返回结构化的来源；
-`api/source_tracker` 从 ToolMessage 里抽取并去重。
-
-**不要在提示词里要求模型「记得写引用」**。模型漏写和编造这两种失败模式
-无法在事后可靠区分；读工具返回值就不存在这两个问题。
-
-### 5. 摘要压缩用框架的中间件，不自造
-
-deepagents 的 SummarizationMiddleware 会把被淘汰的历史**追加落盘**到
-`/conversation_history/{thread_id}.md`，并把路径嵌进摘要正文，agent 之后
-能自己 `read_file` 找回来。
-
-两个后果要记住：
-
-- **不要再传一个 SummarizationMiddleware 给 `create_deep_agent`**。
-  `create_agent` 会校验中间件 `name` 唯一，重复直接抛
-  "Please remove duplicate middleware instances"（1.5 时代靠同名替换的
-  做法在 deepagents 0.6.x 已失效）。
-- 要关掉压缩，用 `CTX_COMPACT_ENABLED=0`（内部走
-  `HarnessProfile.excluded_middleware`）。关掉会**同时失去历史落盘能力**，
-  长会话会硬撑到超窗报错。
-
----
-
-## 二、踩过的坑（别重犯）
-
-这些都在开发过程中真实触发过，症状与原因距离很远，所以单独记下来。
-
-### 坑 1：环境变量与 `.env` 的优先级
-
-机器上存在全局 `OPENAI_API_KEY`（实测遇到过一把无效的）时，进程环境会盖掉
-项目 `.env`。症状是「密钥明明配对了却报 401，且报错里显示的密钥后几位和
-`.env` 里的不一样」。
-
-`config.py` 把它做成**显式可配**的 `DEEP_AGENT_ENV_PRIORITY`：
-
-- `dotenv`（默认）：`.env` 优先。防「被污染的 shell 静默改掉项目配置」
-- `process`：进程环境优先。**跑变体实例必须用这档**，例如
-  `DEEP_AGENT_ENV_PRIORITY=process DB_DIALECT=mysql PORT=8081 python main.py`
-- `none`：完全忽略 `.env`（测试/CI 用）
-
-为什么默认不是 `process`：两种失败模式代价不对等。`dotenv` 的代价是「有意的
-环境变量覆盖不生效」——加个前缀就绕过，且启动日志会告诉你；`process` 的代价是
-「本机某个无关的全局变量静默改掉项目配置」——表现为身份诡异的 401 或连错库。
-
-**无论哪一档，冲突都会打 WARNING 并把键名暴露给 `/health` 的
-`config_conflicts`**，包括「生效值长什么样」（脱敏）。这条可见性是本机制的核心
-价值：它把「配置没生效」从玄学变成一行日志。
-
-注意 `process` 档会放行**所有**环境变量，包括那把无效的全局密钥——所以跑变体
-实例时要连密钥一起显式传入，不要只传你要改的那几项。
-
-### 坑 2：`MemorySaver` 之外，checkpointer 必须显式声明上下文窗口
-
-摘要中间件的 `trigger=("fraction", x)` 依赖模型 `profile["max_input_tokens"]`。
-不声明的话，框架在首次触发压缩时报错而不是降级。
-
-`agents/model_factory.build_model` 无条件设置 `profile={"max_input_tokens": window}`。
-新增任何模型构造路径都要照做。
-
-### 坑 3：子智能体的 `tools` 必须是 `BaseTool`，主 agent 的 `tools` 可以是裸函数
-
-两者要求不同：主 agent 的 `tools=` 由框架包装，子智能体的 `tools` 会被直接
-塞进 `ToolNode`，那里要读 `tool_.name`。传裸函数会炸在 `tool_.name` 上，
-而堆栈只指向 `SubAgentMiddleware`，看不出是参数形态问题。
-
-用 `tools.registry.get_tools_by_name([...])`，它返回 `BaseTool` 列表。
-
-### 坑 4：自定义中间件的同步/异步钩子都要实现
-
-只实现 `wrap_model_call` 而服务全程走 `astream` 时，运行期抛
-`NotImplementedError`，报错位置在模型节点内部。
-
-`agents/middleware.DynamicTimeMiddleware` 同时实现了 `wrap_model_call` 与
-`awrap_model_call`。
-
-### 坑 5：ToolMessage 也走 `messages` 通道
-
-`stream_mode=["updates","messages"]` 的 messages 通道里不只有
-`AIMessageChunk`，`ToolMessage` 也在推。不过滤的话，工具返回的原始 JSON
-会混进给用户看的正文。
-
-对策：只在 `isinstance(chunk, AIMessageChunk)` 时发 `token` 事件。
-同理，摘要中间件的模型调用也在同一通道，靠 `metadata["lc_source"] ==
-"summarization"` 过滤。
-
-### 坑 6：图输入必须是 dict
-
-`astream({"messages": [...]})`。传裸 list 会被当成 `__start__` 节点的返回值，
-报 `InvalidUpdateError: Expected dict, got [...]`。
-
-### 坑 7：`load_builtin_tools` 对已导入模块是空操作
-
-工具的注册靠**模块体里的装饰器**，而 `import_module` 对 `sys.modules` 里
-已有的模块不重放模块体。所以「清空注册表后重新装载」必须显式 `reload`，
-否则注册表一直是空的，表现为「工具莫名其妙全没了」。
-
-### 坑 8：时间戳精度决定消息顺序
-
-`created_at` 只到秒时，同秒写入的 user/assistant 两条消息只能靠随机 UUID
-做次级排序，顺序会随机颠倒——冷启动补种图状态时会把「谁说了什么」喂反。
-
-`db.db_conn.fmt_dt` 输出到微秒，MySQL 侧对应 `DATETIME(6)`。
-
-### 坑 9：两个计量器之间没有自动连接
-
-`ContextMeter`（算上下文占用与用量）与 `billing.meter.UsageMeter`（入账）
-是分开的。收尾时必须显式把前者的数字 `add` 给后者——漏了这一步，
-交互式对话全程**不会计费**，而 `/usage/today` 显示 0，表面看「一切正常」。
-
-### 坑 10：权限规则**首条命中即返回**
-
-`FilesystemPermission` 是逐条匹配、命中即返回。所以具体的 `allow` 必须排在
-宽泛的 `deny` 之前，否则 `deny /**` 会把后面的 allow 全部短路，agent
-连技能文件都读不到。
-
-### 坑 11：`python main.py` 会让模块被导入两次
-
-`uvicorn.run("main:app")` 会再导入一次 `main`，于是模块级副作用执行两遍
-（一次作为 `__main__`，一次作为 `main`）。日志会重复，配置会被构造两次。
-
-**副作用一律放进 lifespan**，模块级只留纯定义。
-
-### 坑 12：工具卡必须按 `tool_call_id` 索引，不能按工具名
-
-同一轮里同一个工具会被调多次（实测 agent 会自己换关键词连查 4 次）。
-只按 `tool` 名索引卡片 → 后一次的结果挂到前一张卡上，界面看起来「结果和
-参数对不上」。
-
-1.5 的契约里没有 `tool_call_id`，2.0 补了它作为**附加字段**（`sse_events`
-的 tool_call / tool_result）。附加字段安全、改名不安全——见 §四的契约纪律。
-
-### 坑 13：`element.textContent += x` 会摧毁子元素
-
-`textContent` 的读是「所有后代文本的拼接」、写是「替换全部子节点」。所以
-`bubble.textContent += token` 这类写法会：① 把子元素（工具卡片）的文本一起
-读进来，② 赋值时把那些子元素整个删掉。表现是工具卡片被抹成一坨纯文本，
-而且每次追加都重新拼接全文（O(N²)）。
-
-正确做法是给正文一个独立的文本节点，并在插入卡片时「断开」当前文本段，
-以保留时间顺序（见 `static/index.html` 的 `appendToken` / `addCardFor` /
-`breakSegment`）。
-
----
-
-## 三、分层与依赖方向
-
-```
-main.py ──> api/ ──> agents/ ──> tools/
-                └──> billing/ ──> db/
-                └──> scheduler/
-        所有层 ──> obs/ 与 config
-```
-
-规则：
-
-- **`db/` 不反向依赖上层**。业务逻辑不进 store，store 只做存取。
-- **`billing/` 不依赖 `api/`**。计费只接受标量参数，不认识 `StreamRequest`。
-- **`tools/` 不依赖 `agents/`**。工具是纯函数，拿不到 agent。
-- **`obs/` 与 `config` 可以被任何层依赖**，它们不依赖任何业务层。
-- 跨层取配置一律走 `config`，不要在业务代码里 `os.getenv`。
-
----
-
-## 四、编码约定
-
-- **每个配置项必须有默认值**，且默认值 = 「不配也能跑起来」的那套。
-  新增开关的默认值不得改变既有行为。
-- **对外契约的字段名只在 `api/sse_events.py` 声明**。其他任何地方都不得
-  手拼 `data: ` 字符串——字段改名漏掉一处，前端就静默渲染失败。
-- **契约只做加法**：新增字段安全（旧前端忽略未知字段），改名或删除不安全
-  （静默破坏渲染）。要改已有字段名，先确认 1.5 前端也一起改。
-  **唯一的例外是删掉 `POST /api/chat/only`**（见 §六），那是一次经过评估的、
-  有记录的收缩——不是「删了也无所谓」的先例。
-- **函数式注释写「为什么」不写「是什么」**。行内注释只在代码本身无法表达
-  约束时写（顺序要求、副作用、反直觉的取舍）。
-- **同步驱动（pymysql / sqlite3）在 async 路由里必须走 `asyncio.to_thread`**，
-  否则单进程下一个人查历史会卡住所有人的流。
-- **工具失败返回可读原因，不抛裸异常**。抛异常会打断整轮工具调用，
-  返回错误说明能让模型自己纠正。
-- 文件规模控制在 500 行以内（1.5 的约定）。超了就拆。
-
----
-
-## 五、验证方式
-
-```bash
-# 1) 离线单元 + 契约测试（不需要模型密钥，不需要数据库服务）
-python -m pytest
-
-# 2) HTTP 层端到端（需要服务已启动 + 可用的模型密钥）
-python main.py &                     # 或 bash scripts/start_server.sh start
-python scripts/http_e2e.py
-
-# 3) 只做导入与语法自检
-python scripts/selfcheck.py
-```
-
-三者的分工：
-
-| 检查 | 覆盖 | 何时跑 |
-|---|---|---|
-| `pytest` | 单元逻辑 + SSE 契约字段 + 内核通道分工（用假 agent） | 每次改动 |
-| `scripts/http_e2e.py` | 真实 HTTP + 真实模型 + 落库 + 中断闭环 + 调度 | 提交前、发布前 |
-| `scripts/selfcheck.py` | 导入、建表、agent 编译、工具注册 | 改结构后快速自检 |
-
-**改 SSE 事件字段必须同步改 `tests/test_sse_contract.py`**——那里的断言就是
-兼容性契约本身。
-
----
-
-## 六、已知缺口（有意为之，不是遗漏）
-
-列在这里是为了让读代码的人知道「这里没写不是因为忘了」。
-
-### 为什么没有 `/chat/only`
-
-1.5 有 `POST /api/chat/only`，2.0 **删掉了**。如果你正想「为了兼容 1.5 把它加
-回来」，先看这段。
-
-它和 `/chat` 的差别只有计费流水上那个 `kind` 标签（`chat` vs `chat_only`），
-**行为完全相同**。而那个标签在 1.5 和 2.0 里都没有任何消费方：没有按渠道聚合
-的接口、没有按渠道拆的额度、没有渠道维度的报表。也就是说它看起来像渠道区分，
-实际不承载信息。
-
-这份重复在 1.5 有可查的代价：
-
-- **出过计费 bug**：`docs/实施记录-B3-P3.md` 的 R7-#24 / P1-11 ——
-  「/chat vs /chat/only 标题计费口径不一致」。两个本该一致的入口漂移了。
-- **多付一份安全验证**：`tests/l4_auth_runtime.py` 里的 `L4-1b-c2`（thread_id
-  越权）与 `L4-8c`（413 体积闸）存在的唯一理由，是在第二个入口上再证一遍同样
-  的阀门。
-- **多养一个专用探针**：`tests/probe_b345_dedup_diff.py` 的唯一职责是证明两者
-  行为相同。
-- **最终被收敛**：B3-45 提交说明写着「/chat vs /chat/only 95% 重复，抽
-  `_run_chat_pipeline`」——1.5 自己也认定它是重复，只是出于兼容留了端点、只删
-  了重复实现。
-- 而 1.5 前端**从头到尾 0 次调用** `/chat/only`。
-
-要重新引入这类入口，正确的顺序是**先把渠道差异做实**（按渠道聚合用量、按渠道
-拆额度、渠道维度报表），再引入入口；不要先立一个行为相同的端点，指望以后有人
-去消费那个标签。
-
-保留的另两个入口 —— `/chat/resume`、`/chat/interrupt` —— 不属于这类：它们承载
-的是**不同能力**（中断恢复、挂起查询），不是同一能力的别名。
-
-1. **没有鉴权**。`/api/chat` 直接取 multipart 的 `user_name`（缺省 `default`），
-   客户端可自报身份。计费、会话归属、并发配额全建立在这个值上，所以
-   **当前只适合内网或开发环境**。接真实鉴权时替换
-   `api/chat_routes._resolve_user` 为 `Depends(...)` 即可，其余代码不用动。
-2. **没有业务工具与业务技能**。只有 4 个演示工具（时间/检索/计算/计划审批）
-   与 1 个示例技能。业务工具照 `tools/demo_tools.py` 的模子加。
-3. **没有 MCP 接入**。1.5 的 `tools/mcp_client_pool.py` 等未移植。
-4. **会话标题用截断而非 LLM 生成**（`_ensure_session_title`）。省一次模型
-   调用的钱和延迟；想换只改那一个函数体。
-5. **并发计数是进程内的**。见不变式 2。
-6. **`remember` 长期审批规则未实现**。`ResumeRequest.remember` 收到即忽略。
-

-
-| 文件 | 相关纪律 |

+# 多业务智能体与陕西局接入
+
+本服务保留 vent_agent_2.0 执行框架，初期单应用进程运行。主协调 Agent 处理综合聊天，业务 Agent 既可接受委派，也可按名称独立执行。当前仅注册 `main_fan`；其他业务职责确认后增加扩展，不创建占位智能体。
+
+## 存储和配置
+
+默认 `DB_DIALECT=sqlite`、`DB_SQLITE_PATH=data/vent_agent.sqlite`。业务任务、文件索引、会话、用量及推送回执进入本库；图状态使用 `CHECKPOINT_DB_PATH=data/checkpoints.sqlite`。SQLite 使用 WAL 和连接锁，保持单进程部署。切换数据库配置不自动迁移 MySQL 历史数据。备份需在停机或使用 SQLite 在线备份机制时同时保存业务库、checkpoint 和 `data/workspaces/`。
+
+主通风机研判默认开启，配置 `MAIN_FAN_ENABLED=0` 可关闭。支持双机报告参数、同条件性能数据及切换前后稳定风量比较。`completed` 表示业务执行完成，具体结论使用 `judgment.resultCode`。详见 [主通风机业务与模拟联调](MAIN_FAN.md)。
+
+## 增加业务
+
+在 `extensions/<业务名>/extension.py` 中调用 `registry.register_business_agent(...)`，声明 name、display_name、description、prompt、tools、input_schema、result_schema、max_concurrency。`GatewayBinding` 声明取数身份，`ResultBinding` 声明结果平台身份，二者独立。示例见 `extensions/main_fan/`。
+
+输入和结果使用 Pydantic schema；平台任务结果应继承 `runtime.business_models.JudgmentResult`。业务工具绑定到专业 Agent，主协调 Agent 经委派使用，保留通用工具。专业 Agent 的独立图分别编译和缓存；全局模型更新失效所有缓存。会话绑定 Agent，不能在已有会话切换业务，否则返回 409，应新建会话。
+
+自主探索业务额外声明 `skill_path="/skills/<名称>/SKILL.md"`。这类 Agent 不强迫模型再输出结果 schema：由最终提交工具将校验后的正式结果写入 `structured_response`，`SkillCompletionMiddleware` 结束调用，结果 validator 和 schema 仍在宿主归档时执行。工具失败返回反馈时不会结束，模型可修正后继续。未声明 skill_path 的业务保留原结构化输出方式。
+
+主协调 Agent 的 `task` 委派与独立图共用业务定义和启停检查。独立任务额外使用业务级并发上限；全局并发、会话互斥、超时、checkpoint 和计费仍由 runtime 统一处理。
+
+## 按名称执行
+
+网页新会话选择“矿井主通风机研判智能体”；已有会话沿用绑定的智能体。`POST /api/chat` 新增可选 multipart 字段 `agent_name`，缺省为综合助手，新会话填 `main_fan` 可独立执行。恢复和历史查询自动使用原 Agent。
+
+非 HTTP 脚本可以直接执行：
+
+```python
+import asyncio
+from db import chat_store
+from runtime.environment import RuntimeEnvironment
+from runtime.execution import execute
+
+async def main():
+    async with RuntimeEnvironment():
+        session = chat_store.create_session("report-user", "full")
+        result = await execute(
+            agent_name="main_fan", user_name="report-user", session_id=session["id"],
+            message='输入：{"mine_code":"测试矿井编码","mine_name":"测试煤矿","materials":[]}',
+        )
+        print(result.status, result.structured_output or result.output)
+
+asyncio.run(main())
+```
+
+## 持久化任务 API
+
+主网页服务会启动 `RuntimeEnvironment(business_jobs=True)`，独立脚本默认不启动队列。业务 API 服务凭证是自己的 `BUSINESS_API_TOKEN`，与网关通讯凭证不同；未配置时受保护接口返回 503。该凭证不替代已有聊天 API 的用户鉴权。
+
+| 方法 | 路径 | 用途 |
+|---|---|---|
+| GET | `/api/business-agents` | 公开业务目录，无凭证 |
+| GET | `/api/business-agents/{name}/schema` | 输入和结果 schema，无凭证 |
+| POST | `/api/business-agents/{name}/jobs` | 提交任务，返回 202，需自己的 Bearer 凭证 |
+| GET | `/api/business-agents/{name}/jobs` | 按 user_name 查询任务，需凭证 |
+| GET | `/api/business-agents/{name}/jobs/{id}` | 任务详情，需凭证及匹配 user_name |
+| GET | `/api/business-agents/{name}/jobs/{id}/result` | 获取与实际推送一致的新格式 JSON，需凭证 |
+| POST | `/api/business-agents/{name}/jobs/{id}/publish` | 将已保存结果加入独立结果平台队列，需凭证 |
+| POST | `/api/business-agents/{name}/jobs/{id}/retry` | 重试失败/取消/意外中断任务或失败推送，需凭证 |
+| GET | `/api/business-agents/{name}/status` | 本地启停状态、业务与推送统计，需凭证 |
+| POST | `/api/business-agents/{name}/manage?action=start\|stop\|restart` | 单业务逻辑启停，需凭证 |
+
+任务请求示例（所有矿井值均为测试占位，正式值由平台提供）：
+
+```json
+{
+  "request_id": "main-fan-demo-001",
+  "user_name": "default",
+  "input": {"mine_code": "test-mine", "mine_name": "测试煤矿", "fan_id": "F1", "materials": []},
+  "files": [],
+  "publish": false
+}
+```
+
+同一业务、用户、来源和 request_id 重复提交返回原任务；改变输入时拒绝。模型成功执行与业务正式研判完成分开记录。任务 API 中，业务 `completed` 且请求 `publish=true` 时进入推送队列；网页/工具调用在结果平台启用且 `MAIN_FAN_AUTO_PUBLISH=1` 时自动入队。结果保存后推送重试不会再次调用模型或识别原件。网络错误和 429/502 等暂时故障退避重试，最多10次；永久错误保留结果及失败状态，可通过 publish/retry 接口重新排队。
+
+意外停机时运行中的任务标为 interrupted，需明确重试，避免重复模型调用；已保存的待推送结果重启后继续推送。等待审批的任务记为 waiting_input，通过现有 `/api/chat/resume` 恢复（携带会话、user_name 和 interrupt_token）；队列执行器同步结果。
+
+## 连接对方网关
+
+填写以下配置后重启服务：
+
+```dotenv
+SHANXI_GATEWAY_ENABLED=1
+SHANXI_GATEWAY_URL=对方提供的网关根地址
+SHANXI_GATEWAY_TOKEN=对方提供的网关通讯凭证
+MAIN_FAN_AGENT_CODE=平台分配的编码
+```
+
+客户端为每个业务显式携带 X-Agent-Code，不共享可变的全局身份。网关用于 JSON 接口转发和下载凭证下发；应用启动时不注册业务、不建立网关 SSE 控制连接，也不向网关上传或推送结果。本地业务启停走自己的 manage API。旧数据库 `gateway_online` 字段仅为历史兼容，不再作为业务准入条件；单次取数失败仍正常记录为任务失败。旧的 `MAIN_FAN_CHECK_TYPE_CODE`、`MAIN_FAN_TOPICS`、`MAIN_FAN_SENSOR_TYPES` 不再参与运行时接入。
+
+### 文件获取
+
+文件列表、下载路径、参数和业务触发源由对方提供，当前不预设具体通风接口。`SHANXI_FILE_BASE_URL` 是文件所属系统根地址。任务 files 示例：
+
+```json
+{"file_id":"report-001","version":"v1","filename":"主通风机报告.pdf","path":"/对方提供的下载路径","params":{"id":"report-001"}}
+```
+
+先向网关获取 access_token/client_id，再直连文件系统流式下载，限制大小、不跟随跳转。文件进入会话 `/workspace/uploads/` 并记录版本、大小和 SHA256。下载返回 JSON、空文件、凭证不可恢复等会使任务失败，不把错误响应当成文件。401/403 仅在重新取得不同凭证后重试一次；当前网关仅在空 token 时刷新，已过期凭证重复下发需对方解决。
+
+## 独立结果平台
+
+配置与取数网关完全分开，`RESULT_PLATFORM_URL` 是完整接收接口地址：
+
+```dotenv
+RESULT_PLATFORM_ENABLED=1
+RESULT_PLATFORM_URL=http://127.0.0.1:8767/api/judgments
+RESULT_PLATFORM_TOKEN=local-result-platform-token
+RESULT_PLATFORM_AUTH_HEADER=Authorization
+RESULT_PLATFORM_AUTH_SCHEME=Bearer
+RESULT_PLATFORM_SUCCESS_FIELD=code
+RESULT_PLATFORM_SUCCESS_VALUES=0,200
+MAIN_FAN_RESULT_AGENT_CODE=main_fan_equivalence_agent
+MAIN_FAN_RESULT_AGENT_NAME=矿井主通风机同等能力研判
+MAIN_FAN_AUTO_PUBLISH=1
+```
+
+以上为本地接收平台的接口及凭证。正式环境替换为对方提供的值。自定义 API Key 头可配置 AUTH_HEADER，例如 X-API-Key，并设 AUTH_SCHEME=none；无鉴权接口显式设 AUTH_HEADER=none。接收成功以 HTTP 204，或 HTTP 2xx 且 JSON 中配置的成功字段匹配成功值为准。支持 `data.code` 等嵌套字段；HTTP 200 的业务失败、HTML 登录页或任务身份不符不计成功。完整回执保存在 `receipt_json`。
+
+每条报文对应“矿井＋同组主备风机＋一次研判”，所有叶子字段都是字符串：
+
+| 字段 | 内容 |
+|---|---|
+| agentCode / agentName | 结果平台的智能体身份，与网关取数身份分开 |
+| taskId | 32位任务标识，同次任务重试保持不变 |
+| checkedAt | 研判完成时间，Asia/Shanghai，yyyy-MM-dd HH:mm:ss |
+| mineCode / mineName | 实际输入并校验过的矿井身份 |
+| objectDetail | 同组两台设备的名称、标识、研判内容 |
+| dataDetail | 实际参与分析的资料来源、时段、指标和阈值 |
+| judgment.resultCode | NORMAL / WARNING / ABNORMAL / UNDETERMINED |
+| judgment.result | 一句列表结论 |
+| judgment.reason | 完整整体报告，去除内嵌图片编码和 Markdown 表格标记 |
+| judgment.evidenceLink | 已部署的外部证据页地址；当前为空字符串 |
+
+`NORMAL` 只要求三项通过：两台风机报告基础参数一致（型号、额定功率及共同载明的基础参数）、停机至启动间隔≤10分钟、切换前后稳定风量差≤10%。叶片角度、备用台账可用性、补充曲线/风压指标、普通OCR说明和表图差异不增加否决条件；表图差异在报告中独立说明。明确的一般参数差异、切换间隔超过10分钟或风量差大于10%且小于15%输出 `WARNING`；有效证据确认风量差达到15%输出 `ABNORMAL`；关键数据不足或冲突、无法有效比较时输出 `UNDETERMINED`。10分钟、10%的等于边界仍为通过。规则文件的 `severity` 分别配置严重风量差、严重切换间隔与严重参数字段，目前风量严重线为15%，另两项留空；严重规则仅针对有有效证据且已不通过的对应项目。`ABNORMAL` 是业务规则异常，不自动等同于法律上的重大隐患认定。
+
+内部 MainFanResult 保留 `analysis_id`、`workflow_id`、证据及计算记录，新格式报文存入 `platform_payload`。网页继续显示整篇报告；任务的 `/result` 接口直接返回报文。普通网页研判也可通过 `GET /api/business-agents/main_fan/analyses/{analysis_id}/result?session_id=...&user_name=...` 查询，使用 BUSINESS_API_TOKEN。模型只能返回工具凭据，服务端从同用户、同会话 SQLite 原件恢复，不能改写编码、数值或结论。
+
+首次入队即冻结报文和接收地址，数据存于 `business_jobs.push_payload`、`business_push_targets`。重启和重试沿用同一 taskId、checkedAt、正文及 Idempotency-Key。修改接收地址或智能体身份后，不自动把历史待推送结果改投新平台。原文件和计算记录继续由我们管理，不经网关上传。旧格式历史结果不会被自动改写或重发，需重新执行研判产生新格式结果。
+
+### 本地接收联调
+
+另开终端运行 `.venv/bin/python scripts/mock_result_platform.py`，默认端口8767，独立库 `data/mock_result_platform.sqlite`。取数网关仍在8766，网页仍在8080。浏览器访问 `http://127.0.0.1:8767/docs`，Authorize 填入上述本地接收凭证，调用 GET /api/judgments 查看收到的原文和回执。重复的 agentCode/taskId 返回相同回执，内容发生变化则409；重启接收服务不会丢记录。可加 `--fail-first 1` 验证首次503后恢复推送。
+
+## 验证
+
+运行 `.venv/bin/python -m pytest` 和 `.venv/bin/python scripts/selfcheck.py`。测试使用独立 SQLite、假模型、取数网关和独立接收平台，不需要外部访问权限。真实联调还需网关取数信息，以及结果平台的接口地址、鉴权和成功回执约定。

+# 矿井主通风机业务与模拟联调
+
+`main_fan` 在我们自己的框架内执行，陕西局网关负责对外管理和转发。默认联合研判同矿井、同组的两台主通风机，比较检测报告参数、实测性能数据，以及有真实时序输入时的切换前后稳定风量和风压。
+
+业务 Skill 为 `skills/main-fan-equivalent-capability-assessment/SKILL.md`。当前模式是沙箱自主探索：Agent 自行编写文档解析、取证、计算、图表和报告生成代码，在会话沙箱中执行，根据真实输出修改方法。原七阶段、文档识别器、事实登记器和独立计算器不在默认工具集中；旧服务仅用于显式兼容脚本。
+
+## 沙箱自主探索工作台
+
+当前仅注册四个入口：
+
+| 工具 | 职责 |
+|---|---|
+| `prepare_main_fan_task` | 绑定身份，导出原始输入、规则和交付 schema |
+| `fetch_main_fan_data` | 通过宿主网关取得原件、设备与运行记录 |
+| `run_python` | 隔离执行 Agent 自己编写的代码，保存真实输出和执行记录 |
+| `submit_main_fan_report` | 核验交付文件与执行记录、映射平台格式并归档 |
+
+文档文本提取、页面渲染和字段整理使用 Agent 自编 Python；扫描件由它渲染 PNG 后通过通用 `read_file` 看图。中间事实结构由 Agent 自行设计，不再登记到固定 DocumentFacts。标准库、numpy、pypdfium2、Pillow 和 cv2 已可使用；沙箱不联网、不注入服务端凭证、不运行时安装依赖。业务要求、单位和阈值写在 Skill 与本轮冻结的 `rules.json`。
+
+macOS 使用 sandbox-exec，Linux 需要 bubblewrap；缺少沙箱时报不可执行，不回退为宿主裸执行。默认单次最长120秒、单会话最多40次。配置项为 `AGENT_PYTHON_MAX_SECONDS`、`AGENT_PYTHON_MEMORY_MB`（仅Linux地址空间）、`AGENT_PYTHON_MAX_RUNS`。
+
+Agent 用代码生成 Markdown、AgentAssessment JSON 及需要的附件，声明 `output_paths` 并带 `workflow_id` 执行。提交时必须关联本轮成功 `run_id`，报告、JSON、附件的哈希必须仍与声明输出一致。宿主只核验身份、原件与可信输入指纹、来源归属、文件格式及执行记录，不重新 OCR、不复算窗口或核心指标、不改写结论和正文。业务结论和平台摘要来自 Agent 的 JSON；算法与文字正确性由 Agent 按 Skill 核对，执行成功本身不证明结论正确。
+
+原始输入、规则版本、实际操作和最终结果保存在 `main_fan_workflows`、`main_fan_analyses`。派生文件在会话 `/workspace/`，宿主另存受保护的代码快照和执行凭据。工作台显示实际操作，不预设七阶段；探索步骤预算默认480，由 `AGENT_EXPLORATION_RECURSION_LIMIT` 控制。详细交付格式见 Skill 下的 `references/workbench.md`。
+
+## 2026-10-19 改造验证
+
+563 项离线回归通过，包含实际 macOS 沙箱中的 PDF 渲染、库加载、文件/网络隔离、执行失败反馈、输出哈希、来源归属，以及真实 Agent 图的写代码/执行/提交与协调委派。网关取数连接保留，默认测试 API 使用完整 Agent。
+
+真实 `qwen3.5-35b-a3b` 扫描件实测中，Agent 自行渲染并查看原页、编写解析/切换分析/报告脚本，得到合成样例的6分钟切换间隔、3800→3610 m³/min稳定风量与5%差异。测试程序随后直接提交其未修改的脚本输出，宿主归档及平台映射通过；这一步不是模型自行完成提交。
+
+最后模型调用被提供方 `429 insufficient_quota / Allocated quota exceeded` 中断，文本PDF最终用例与扫描PDF的完整自动提交尚未完成验收。扫描件报告仍发现电动机型号字段吞入下一行、Measured误标为折算两处质量问题；已补强Skill自检，因配额不足未复测。不得将上述记录表述为真实业务准确性已经验收。
+
+机器可读记录位于 `data/main_fan_live/20261019_sandbox_verification.json`，含测试范围、已验证指标、已知问题及恢复配额后的复测命令。测试使用独立SQLite和checkpoint、合成PDF与时序，未连接真实取数网关或推送正式结果。
+
+## 网页报告输出
+
+最终答复是主通风机与备用风机一致性整体报告，按实际数据动态选择基础参数、性能数据、切换工况和已有资料差异章节。没有数据的项目不进入正文，不列缺件清单，不添加“（需复核）”标签。两机参数来自各自报告，额定功率的组合表达式由 Agent 编写代码解析；性能差异在共同实测风量区间内插值，禁止外推。角度未知时仅输出同频报告数据差异，不判定同角度曲线等价。
+
+综合结论只采用基础参数一致、切换间隔≤10分钟、切换前后稳定风量差≤10%三项，全部通过即为 `NORMAL`。一般明确偏差为 `WARNING`；风量差达到15%且对应数据有效为 `ABNORMAL`；关键比较数据无法形成有效对照时为 `UNDETERMINED`。严重间隔及严重参数条件尚未设定。普通OCR说明、未知叶片角度/台账状态、补充性能曲线或风压差异不额外否决综合结论，表图差异单列说明。阈值来自 `examples/main_fan/equivalence_rules.json`，按版本保存到每次工作流。
+
+报告使用 m³/min、Pa、kW 和 Hz，保持原始值及转换公式；Agent 根据有效数据决定是否绘制双机性能图、切换图或比较表，图表由其代码或实际计算结果生成。切换分析只使用经确认归属、有明确来源的时序数据和整台风机状态/切换记录；单级开停截图、单点风速不作切换窗口或风量依据。模拟数据在报告与来源栏明确标注。只比较风量时，报告不把风压也写成已判定通过。
+
+规则和阈值配置位于 `examples/main_fan/equivalence_rules.json`，可通过 `MAIN_FAN_RULES_FILE` 替换。初始配置来自需求中的建议值，不表述为法规限值。执行状态与综合判定状态分开：部分项目有结果时报告只陈述这些结果，Agent 应在交付 JSON 中明确未评估项目和证据限制。
+
+自主模式的提取事实与计算细节保存在 `assessment.agent_result.details`，来源引用在 `assessment.evidence`，代码执行记录在 `assessment.exploration`；不再由固定算法生成 `analysis`。网页工具详情默认折叠，文件来源保留显示；最终正文恢复 Agent 实际提交的原件。
+
+单机报告版本的历史实测记录位于 `data/main_fan_live/20261014_report_style_5eda22f9/`；该版本当时只分析1号，当前默认流程已改为双机。显式设置 `paired_assessment=false` 仅用于旧单机接口兼容。
+
+双机版本网页实测记录：`data/main_fan_live/20261014_pair_verified_20a71196/`。实际请求为“审核众源煤业主通风机及备用是否一致”，从原件模拟网关下载26页PDF和两张系统截图，16次实际视觉模型调用（含一次图注分类回读），未使用旧缓存或人工转录。两台各44行数据，88行公式检查；30、40、50Hz均形成共同风量区间的数据比较。截图识别出另一矿井的设备与风速，未混入本矿井报告。正文约2500字符（含Markdown表格，不计SVG编码），只含有数据的参数、性能和实际资料差异章节。
+
+文档识别对风量原文单位、轴功率含义和表图工况分类进行一致性检查，疑似记录自动放大回读原页；仍缺明确单位或轴功率依据的行退出计算，原值不按公式反算修正。缓存升级至v4，旧识别记录不自动复用。
+
+## 历史服务的资料与实测记录
+
+下列原件核验和历史实测基于此前固定服务，不代表本次自主探索改造已完成模型联调或测试。
+
+当前目录有一份 26 页扫描 PDF，`风机数据截图/` 子目录内有两张裁切截图。原件模拟网关递归建立文件索引。PDF 包含陕西众源煤业集团有限公司的 1、2 号主通风机报告，编号分别以 `0003`、`0004` 结尾；检验日期为 2022-03-18、2022-03-17，报告所载建议下次日期为 2025-03-17、2025-03-16。
+
+截图属于神木市瓷窑塔矿业有限公司，不能与上述报告合并。只转录完整可见行：设备 `00000540` 为“地面主通二号二级/开”，`00000541`、`00000542` 为“一号一级/停”“一号二级/停”；开停截图未提供采集时间。测点 `2000000TJFJ010038` 为“一号风机风速”，值 0 m/s、状态正常，时间 2026-10-13 10:13:00；下方温度行不完整，未转录。
+
+[reviewed_sample.json](../examples/main_fan/reviewed_sample.json) 是旧离线联调夹具，保存人工核验转录、原文件 SHA256 和 PDF 物理页码；生产自动识别和原件实测不加载它。`mock-ci`、`mock-zy` 是模拟编码，实际矿井编码未知。
+
+1 号报告物理页 8 的现场运行表工况静压为 523.57 Pa、效率 64.77%；物理页 11 曲线图注为 511.73 Pa、63.30%。自动识别把图注与数据表分开保存，保留两处差异供复核。旧离线夹具只覆盖身份和各 7 行 30 Hz 现场数据。
+
+## 规则边界
+
+| 输入 | 实际处理 |
+|---|---|
+| 矿井编码或名称冲突 | 排除记录；不模糊合并公司名称 |
+| 名称、编号、位置线索 | 同矿井风机号形成 candidate；PLC1、一级/二级不作风机号 |
+| 人工确认关联 | 须提供 point_code、fan_id、confirmed_by、reason；冲突仍阻断 |
+| 重复、断线、缺时、过期、未来时间、未知单位 | 保留发现，排除当前计算 |
+| 单点风速 | 不直接换算风量；缺断面与平均风速时说明缺件 |
+| “风压”、电输入功率 | 不冒充风机静压增量或轴功率 |
+| 当前效率 | 唯一、已确认关联、有效且同步的 Q、静压、轴功率才计算 |
+| 历史报告 | 同矿井且对应目标风机时复核同一行，不混用现场和折算值 |
+| 建议检验日期已过 | 提示核查更新报告，不直接认定当前不合格或违法 |
+| 开停快照 | 不根据单台/单级停机推断全矿停风或备用能力 |
+
+静压效率：`eta = Q[m3/s] × p_static[Pa] / (1000 × P_shaft[kW]) × 100%`。支持显式 m3/min→m3/s、kPa→Pa、W→kW 换算。不把静压功率/电输入功率误称为风机轴功率效率。
+
+时效默认 600 秒，同步窗口 120 秒，分别配置 `MAIN_FAN_FRESHNESS_SECONDS`、`MAIN_FAN_SYNC_SECONDS`；它们是数据筛查参数，不是工程安全限值。无时区时间按 Asia/Shanghai 解释。`evaluation_time` 可指定回放时刻并保存在输入；默认当前时间。
+
+`status=completed` 表示初步筛查完成；`judgment_scope=preliminary_screening`，工程状态保持 `review_required` 或 `insufficient_data`，不自动生成红橙黄蓝等级。没有任何本矿井可用资料时为 `needs_materials`。结果保存 `main_fan_analyses`，发布时恢复数据库原件；模型不能改写工具数值后推送。队列工具使用服务端输入，不能自行增加人工绑定。
+
+历史规范仅作为原报告事实保留。当前规程基准核对了应急管理部第 17 号令、2026-02-01 施行的[《煤矿安全规程》](https://www.mem.gov.cn/gk/zfxxgkpt/fdzdgknr/gz11/202508/t20250804_553279.shtml)第 177–179 条。连续运转、备用、改造/换叶片后测定、反风能力需要配置、试验或过程记录；样例不足以核验，不用历史条款数值做当前自动执法判定。规则核对日期：2026-10-14。
+
+## 使用真实模型识别原件
+
+```bash
+.venv/bin/python scripts/run_main_fan_document.py \
+  --document '/Users/gaoshutao/Project/煤科/陕西局代码/测试数据/通风机性能测定报告.pdf' \
+  --mine-name '陕西众源煤业集团有限公司' --fan-name '1号通风机' --agent
+```
+
+默认 `document_cache_policy=refresh`，创建独立 SQLite 与 checkpoint，调用实际 `main_fan` LangGraph 和业务工具。矿井名称只用于任务身份筛查，不作为识别模型的预填答案。不导入人工转录，不使用已有识别缓存，不调用真实陕西局网关。原件复制到本会话附件目录，并验证运行前后的 SHA256 一致。
+
+结果保存在新的 `data/main_fan_live/<id>/result.json`。`--agent` 使用自主模式，Agent 自行选择证据范围，脚本、事实、选页审计及模型原始响应留在本会话 `workspace/exploration/<workflow_id>/`，受保护的代码快照留在同会话 `python_runs/`。不加 `--agent` 才直接调用历史固定服务，其 `document/<附件标识>/facts.json`、`audit.json` 和 `call-*.json` 保存自动提取与逐页调用记录。`--output` 可指定新目录，已有实测数据库不覆盖。
+
+2026-10-14 在本机配置的 `deepseek-flash` 上完成真实模型验证：
+
+| 输入与记录目录 | 实际识别 | 业务执行 |
+|---|---|---|
+| 原始 `通风机性能测定报告.pdf` → `data/main_fan_live/20261014_scan_verified/` | 26 页全部走视觉、13 次实际识别调用；2 份报告、88 行性能数据、2 条数字图注 | 实际 `main_fan` 图；目标 1 号风机 44 行公式复核，最大效率偏差 0.0071 个百分点 |
+| 合成带文本层 PDF → `data/main_fan_live/20261014_native_verified/` | 1 页走文本、1 次实际识别调用，未发送图片 | 实际 `main_fan` 图；合成数据复核 60% |
+
+原件 SHA256 为 `46eb24ec6c0f23907b4dc6f67af00f7907fa15d7acbf04ce13d142a247cfc92a`，扫描识别调用用量合计 76,071 tokens。两种实测均为 `cache_used=false`、`transcript_seed_loaded=false`，数据库缓存方法为 `automatic_extraction`；缓存是在本次完整识别后才写入的。文本 PDF 是独立软件测试输入，不是把原扫描报告转录后冒充可解析 PDF。混合 PDF 另有逐页路由回归测试。
+
+抽查原件物理页 3、8、11、16、21、24 的身份、日期、运行工况和图注。保留 1 号表格 523.57 Pa/64.77% 与图注 511.73 Pa/63.30% 的原件差异；这属于资料复核，不能用历史“合格”结论证明当前设备状态。完整事实未逐字人工验收。全量 381 项测试、结构自检、依赖锁及打包白名单校验通过。
+
+## 离线模拟全链路
+
+```bash
+.venv/bin/python scripts/demo_main_fan.py \
+  --data-dir '/Users/gaoshutao/Project/煤科/陕西局代码/测试数据'
+```
+
+该兼容脚本用两个临时本地端口启动取数网关和独立结果接收平台，在新的 `data/main_fan_demo/<id>/` 创建业务 SQLite、checkpoint、接收平台 SQLite 和 `result.json`，不读取/修改本机 `.env`。会话附件进入框架 `data/workspaces/`，不改变原测试目录。脚本显式调用历史固定服务，经持久化队列、HTTP下载和独立结果推送进行离线联调；不调用外部模型或真实陕西局服务，也不验证自主探索能力。
+
+默认三场景：`original` 原截图与异矿报告，`report` 原报告历史复核，`synthetic` 合成量及合成确认（60 m3/s、500 Pa、50 kW→60%）。随后验证本地业务 stop/start，检查网关没有收到注册、上传或结果推送请求。第三种来源标注 synthetic。可用 `--scenario original|report|synthetic` 单独运行；`--output` 指定新目录，已有演示库不覆盖。
+
+原 PDF 按真实哈希核验，离线识别用人工转录缓存。这验证业务与计算，不能替代视觉模型识别质量验收。
+
+## 单独启动模拟网关
+
+```bash
+.venv/bin/python scripts/mock_shaanxi_gateway.py \
+  --data-dir '/Users/gaoshutao/Project/煤科/陕西局代码/测试数据' --port 8766 --raw-files
+```
+
+默认仅监听 127.0.0.1。`--raw-files` 按当前测试目录直接建立 PDF/图片原件索引，不加载人工转录 JSON；文档中的事实由业务智能体实际识别。启动脚本另外加载下述两份明确合成的时序JSON及其风机身份，不从人工转录夹具填充报告或监测值。原件变动后需重启网关刷新索引。不加该参数则沿用旧离线夹具。业务配置示例：
+
+```dotenv
+SHANXI_GATEWAY_ENABLED=1
+SHANXI_GATEWAY_URL=http://127.0.0.1:8766
+SHANXI_GATEWAY_TOKEN=mock-internal-token
+SHANXI_FILE_BASE_URL=http://127.0.0.1:8766
+MAIN_FAN_AGENT_CODE=mock-main-fan
+MAIN_FAN_DEVICES_PATH=/mock-platform/main-fan/devices
+MAIN_FAN_POINTS_PATH=/mock-platform/main-fan/points
+MAIN_FAN_REPORTS_PATH=/mock-platform/main-fan/reports
+MAIN_FAN_SERIES_PATH=/mock-platform/main-fan/series
+MAIN_FAN_OPERATION_LOG_PATH=/mock-platform/main-fan/states
+```
+
+这些路径、凭证只属于模拟服务。取数身份在网关中预先授权，应用无需运行时注册。真实路径、字段和取数编码需同事提供，没有预设陕西局存在 `/mock-platform/` 接口。
+
+结果接收另起 `.venv/bin/python scripts/mock_result_platform.py`（8767端口），配置 `RESULT_PLATFORM_ENABLED/URL/TOKEN` 后独立推送。正式结果格式、四种编码及推送查询接口见 [独立结果平台](BUSINESS_AGENTS.md#独立结果平台)。
+
+### 开停与风量模拟时序（10分钟、10%规则）
+
+新增 `examples/main_fan/mock_switch_states.json` 和 `examples/main_fan/mock_airflow_series.json`，统一声明 `schema_version=1`、`data_kind=synthetic`、矿井身份、时区、采样间隔和 `series`。每条曲线有 `fan_id`、`samples=[{"observed_at":"带时区时间","value":数值}]`。开停曲线是整机级，`state_scope=whole_fan`，0为停、1为开；风量曲线另有 `sensor_id`、`unit=m3/min` 和显式的 `mapping_confirmed`。两台设备绑定 `mock-zy` 下的 `mock-report-fan-1`、`mock-report-fan-2`。
+
+默认回放2026-10-14 09:20至11:00，每60秒一条，每类数据两台各101点。1号10:00停机，2号10:06启动，双停过渡6分钟。1号切换前风量均值3800 m³/min，2号切换后3610 m³/min，差异5%；停机零值和启动过渡也保留在原始曲线中。
+
+网关代理 `/mock-platform/main-fan/states` 返回整机状态记录，`/mock-platform/main-fan/series` 返回两条风量序列；智能体从状态变化识别切换，不使用预写的切换结论。原始JSON可查看 `http://127.0.0.1:8766/mock/main-fan/curves/switch-states` 和 `/mock/main-fan/curves/airflow`。更换样例目录使用 `--operating-data-dir`。
+
+两项规则独立计算：原机停机至另一台启动的非负间隔 ≤10分钟；`|切换后稳定均值－切换前稳定均值| / 切换前稳定均值 ×100% ≤10%`。等于边界也通过；涨幅、降幅均按绝对差异判断。先启动再停机时另外记录重叠时长，停机等待间隔计0。前窗口取首次切换动作前5分钟之外的30分钟，后窗口取切换完成后5分钟之外的30分钟，默认有效样本完整率≥90%、变异系数≤5%。切换前风量为0不形成比例结论。
+
+整机未知、冲突或连续状态记录缺测超过两个采样间隔时，不跨缺口推断停启时间；未来样本不能补足窗口。没有可比风量时仍能单独保留已证明的切换间隔；只有切换时刻而无停机、启动时刻的旧记录，不自动判定间隔合格。两项通过只表示本次切换与风量规则通过，不替代整体同等能力判识。上述10分钟/10%为本次用户指定业务规则，规则版本随配置归档。
+
+本地网页测试可打开 `http://127.0.0.1:8080/`，在新会话选择“矿井主通风机研判智能体”，只需发送“审核众源煤业1号主通风机”。无需填写矿井编码、工具名或网关/缓存参数，也无需手动上传：业务工具从模拟网关取得目录和文件鉴权，直连下载原 PDF，实际调用视觉模型重新识别。网页聊天的结果保存在当前应用 SQLite；平台推送另由业务任务 API 或网关事件任务触发。
+
+### 简短请求与目标身份目录
+
+`prepare_main_fan_task` 支持目标文字或 `{"target":"众源煤业1号主通风机"}`；业务任务 API 的 input 同样只需一个 target 字段。target 也可以是已配置的风机标识。完整 MainFanInput 协议仍兼容。
+
+```json
+{"input":{"target":"众源煤业1号主通风机"},"publish":false}
+```
+
+服务端设置示例：
+
+```dotenv
+MAIN_FAN_TARGETS_FILE=examples/main_fan/mock_targets.json
+MAIN_FAN_DEFAULT_DOCUMENT_CACHE_POLICY=refresh
+```
+
+目标目录保存矿井名称、经明确配置的别名、矿井编码、风机名称及标识；不包含报告日期、监测数值或人工转录。当前测试目录配置众源煤业 1、2 号风机。自然语言前后缀和“一号/1号/1#”可归一化，但不会模糊搜索公司名称或根据文件内容猜平台编码。未唯一匹配时先询问业务对象，未确定身份前不会取数或分析。
+
+简短请求未带本地材料且网关启用时自动 `use_gateway=true`，默认刷新原件识别。明确提供的附件和显式 `use_gateway`/`document_cache_policy` 会保留；关闭全局网关不会暗中启用 Mock。完整协议输入维持原默认值，队列以服务端已验证输入为准，模型不能通过改写目标或人工绑定改变任务。
+
+测试目标目录明确绑定 `http://127.0.0.1:8766`；真实环境需配置正式身份目录并更新其网关绑定，不能把 Mock 编码用于真实网关。新增矿井在目录里增加身份与别名即可，不需要修改业务 prompt。地址和凭证仍由服务配置决定，用户一句话不能切换网关环境。
+
+2026-10-14 已在运行中的网页仅发送“审核众源煤业1号主通风机”验证完整链路，无附件、无技术参数：自动网关取数和直连下载，实际识别 26 页、13 次文档模型调用，对目标风机复核 44 行；`cache_used=false`、`transcript_seed_loaded=false`。实测记录位于 `data/main_fan_live/20261014_short_request/`，网页会话为 `0a159bbb91dc43c39f9296f35c0fa821`。目标文字、单 target 对象及模型偶尔返回的 JSON 字符串都可解析；全量 411 项测试通过。
+
+用网关内部 Bearer 和 `X-Agent-Code: mock-main-fan` 向 `POST /mock/tasks` 发送 `{"scenario":"original","taskId":"local-001"}`，产生 `main_fan.judgment` 事件。须业务端已注册并订阅；单独启动模式使用你配置的真实语言模型，演示脚本才是离线编排器。
+
+管理模拟：`GET /openapi/agent/manage?agentCode=mock-main-fan&action=stop&token=mock-platform-manage-token`，action 支持 start/stop/restart/status/logs。停止关闭 SSE，重连返回 403；本业务执行和推送暂停，启动后恢复订阅。对方真实网关的指标/日志口径仍按双方约定。
+
+## 历史固定服务的 PDF 识别实现（自主模式不调用）
+
+独立 PDFium 进程逐页判别，不按文件名选择识别方式：
+
+| 页面 | 处理 |
+|---|---|
+| 可读、完整的文本层 | 直接提取文本，由 `MAIN_FAN_TEXT_MODEL` 整理结构；不发送图片 |
+| 空文本、损坏字符、零散水印或大图配少量文字 | 渲染为 PNG，由 `MAIN_FAN_VISION_MODEL` 读取原页 |
+| 曲线图页 | 走视觉；仅录印出的工况数字，不猜曲线像素 |
+| 文本与扫描页混合 | 分别按每页路由，合并到同一文档事实 |
+
+默认最多 32 页，扫描页最长边 2200px，截图最长边 1700px；同一路由每批 2 页。文字模型默认沿用主模型，视觉模型必须明确配置且支持图像。以下设置可独立指定模型、接口和凭证；留空的接口/凭证沿用项目设置：
+
+```dotenv
+MAIN_FAN_VISION_MODEL=deepseek-flash
+MAIN_FAN_TEXT_MODEL=deepseek-flash
+MAIN_FAN_VISION_BASE_URL=
+MAIN_FAN_VISION_API_KEY=
+MAIN_FAN_TEXT_BASE_URL=
+MAIN_FAN_TEXT_API_KEY=
+MAIN_FAN_DOCUMENT_TIMEOUT=180
+MAIN_FAN_DOCUMENT_BATCH_PAGES=2
+MAIN_FAN_DOCUMENT_MAX_TOKENS=20000
+MAIN_FAN_MAX_DOCUMENT_PAGES=32
+MAIN_FAN_ALLOW_MANUAL_CACHE=0
+```
+
+DeepSeek 的文档识别显式关闭思考，使用 JSON 输出模式。视觉与文本分别计入 `main_fan_ocr`、`main_fan_document_text`，不作为主回答流输出，也不重复计费；部署时配置对应模型单价，提供方没有 usage 时标记 estimate。
+
+提取结果校验 schema、PDF 物理页、日期标签及单位，按报告编号累积。JSON/schema 结构异常会重新读取同批原页一次，仍失败则报缺件；截断输出直接报错，避免把不完整结果缓存为成功。数据行或图注的数值与其印出的效率相差超过 0.5 个百分点时，扫描页增加原图放大区域，再读一次；公式只触发复读，不反算覆盖数字，仍不一致则保留原值并提示核验。每次复读同样记录实际模型响应与用量。
+
+旧服务缓存版本为 `main-fan-facts-v4`，支持 `document_cache_policy=auto|refresh|off`；自主工作台只保留本轮识别，不读写共享缓存。不同页出现真实字段冲突时清除该字段并保留候选值与页码；当前自主模式由 Agent 修改自己的提取代码和派生事实后重新执行，代码快照和交付文件哈希留作追溯。制造年月不能替代检验日期，缺 Q/静压/轴功率的行不进入公式复核。
+
+证据方法区分 `text_extraction`、`model_extraction`，保留源文件 SHA256、原文和物理页码。自动识别仍需核对原页，公式正确不证明 OCR 数字正确。业务结果以 SQLite 原件为准，Agent 的代码、派生输出和报告都有各自记录；当前自主模式的平台编码来自 Agent 脚本交付，不由宿主重新计算。
+
+## 旧人工夹具的显式导入
+
+离线调试需要时可以导入已核验的转录：
+
+```bash
+.venv/bin/python scripts/import_main_fan_facts.py \
+  --document '/Users/gaoshutao/Project/煤科/陕西局代码/测试数据/通风机性能测定报告.pdf' \
+  --facts examples/main_fan/reviewed_sample.json
+```
+
+该命令写当前配置的本地库，验证哈希、物理页码和原文，不修改原件。自动识别默认拒绝该缓存；旧 `demo_main_fan.py` 才显式开启人工缓存。其他人工转录使用 `DocumentFacts` JSON 和 `--sha256` 原文档哈希。

+- `algorithms/main_fan/`：事实 schema、确定性关联/筛查/计算、隔离 PDF 渲染。
+- `extensions/main_fan/`：工具、网关 JSON 适配、文档提取、结果和提示词。
+- `db/main_fan_store.py`：文档缓存、分析原件；`business_files` 存队列下载索引。
+- `mock_gateway/main_fan.py`：取数鉴权、JSON代理和文件系统；旧协议接口仅保留兼容测试。
+- `extensions/result_platform/`：独立结果平台的地址、鉴权、回执校验及客户端。
+- `mock_result_platform/`：独立结果接收服务，SQLite存档、幂等及冲突检测。
+- `tests/test_result_platform.py`：四种编码契约、实际规则映射、取数/结果解耦、重试、导出及所有权校验。
+- `tests/test_main_fan.py`：原始数据边界、量纲/身份/时效/同步、真实图、PDF 渲染、原件及模拟网关。
+- `tests/test_main_fan_documents.py`：文本/扫描/混合路由、真实调用协议、缓存隔离、字段冲突与截断处理；其中 PDF 是合成测试输入，不是原报告转录。

+# Vue工作台与智能体测试
+
+打开 `http://127.0.0.1:8080/static/index.html#/test`。对话页继续使用原有聊天、附件上传、SSE、工具审批和历史接口，Markdown统一清理后显示，报告曲线可以点击放大。Vue、Markdown及清理库打包到本地，不依赖浏览器访问CDN。
+
+## 测试方式
+
+主通风机测试页提供三个输入区，配置后点击“运行测试”。下方显示返回JSON、整体研判报告、Excel文件和实际请求记录。测试任务不自动推送结果平台。
+
+1. **测定报告PDF**：选择内置原件或上传PDF，可选择多份以涵盖两台风机。文字版使用文本识别路径，扫描件使用视觉模型；请求中不预先填入报告识别事实。
+2. **两台风机切换曲线**：设置1号→2号或2号→1号，以及停机至备用机启动的间隔（0～120分钟，支持小数）。页面实时绘制整机开停阶跃曲线。也可单独选择或上传开停JSON。
+3. **两台风机风量数据**：设置切换前原运行风机的风量、切换后接替风机的风量，单位m³/min。页面实时绘制两条风量曲线及相对变化幅度。也可单独选择或上传风量JSON。
+
+默认间隔6分钟、风量3800→3610m³/min。服务端按分钟生成完整时序，另插入准确的启动时刻，避免小数分钟被取整；两侧均覆盖稳定运行窗口。合成来源保存在内部证据中，报告参数始终来自本次PDF。
+
+主通风机页面使用 **Skill 驱动的完整智能体**：模型自行规划，在沙箱编写并执行文档解析、计算和报告生成代码；保留网关取数，服务端只在提交时校验来源、文件格式和真实执行输出并归档，不复跑业务计算或固定七阶段。主通风机未声明旧流程 test_runner，工作台不提供绕过 Agent 的固定流程模式。
+
+## 每次独立运行
+
+每次点击运行生成新的request_id、业务会话和独立workspace。agent只挂载本次资料、开停时序和风量数据，不继承其他运行的消息、文件或报告；同一网络请求重试仍按request_id幂等返回已有任务，不重复执行。
+
+三项输入任务由服务器固定`document_cache_policy="off"`：每次仅基于本轮原件自主选择页面识别，既不读也不写共享识别缓存。PDF副本、运行时序JSON、脚本和派生结果保存到该次workspace，执行器另存受保护的代码快照和凭据。历史请求与结果保存在SQLite中供查看，不回填或注入下一次agent上下文。刷新页面只自动追踪尚未完成的任务；已完成历史可从“测试记录”手动打开。
+
+## 上传和选择资料
+
+主通风机三个输入区分别接收PDF、开停JSON、风量JSON。资料库接口仍支持单份不超过50MB的PDF、PNG、JPEG、WebP、JSON、XLSX及CSV，其他业务智能体可使用通用测试入口。
+
+- PDF直接作为本次识别附件；三项输入模式不允许额外夹带合成报告、任意文件路径或网关取数请求。
+- 项目现有 `mock_switch_states.json`、`mock_airflow_series.json` 可直接上传并选择。设备身份、单位和明确的测点归属仍按业务模型校验；选择的时序替换请求中同设备同类型的样例序列。多个上传片段共同校验，不默默只用最后一个文件。
+- 三项输入中的开停JSON须包含同一矿井两台风机的fan_state_records，风量JSON须分别提供两台风机各一条operating_series；也兼容项目现有的schema_version=1时序格式。每个输入槽完整替换对应模拟时序，不混入另一类资料。上传文件要与该次矿井、风机身份及时间范围对应。
+- XLSX、CSV可打开工作表预览。当前主通风机的识别入口接收PDF、图片和结构化JSON，不将任意Excel列自动猜测为风机参数。
+
+`TEST_LAB_SAMPLE_DIR` 指定内置资料目录。未配置时，本地开发会尝试项目同级 `陕西局代码/测试数据/`；目录不存在时可上传自己的PDF。上传库默认在 `data/test_lab/`。内置原件只读，执行时复制到新会话并保存SHA256。
+
+## Excel与JSON输出
+
+返回JSON支持树形展开、完整业务结果/标准平台格式切换、复制和下载。Excel预览直接读取实际可下载的XLSX或CSV，支持工作表切换、合并单元格和常见数字格式；大文件仅预览前300行、60列并显示截断说明。
+
+业务工具可在本地结果中返回：
+
+```json
+{"artifacts":[{"filename":"实际结果.xlsx","path":"/workspace/results/actual.xlsx"}]}
+```
+
+文件必须存在于该测试会话内；前端无法按任意磁盘路径读取文件。实际返回附件标记为“智能体返回附件”。若只有JSON，另提供“结构化结果导出”：主通风机包含研判结论、核心判识项目、基础参数，以及共同风量区间的性能比较数据。导出不重新计算或改写结论。该artifacts字段不改变对外结果平台JSON协议。
+
+## 接口与扩展
+
+工作台接口位于 `/api/test-lab`：catalog、presets、assets（上传/内容/预览）、runs（提交/记录/状态/取消）、runs/{id}/artifacts（下载/预览）。身份沿用本地聊天的user_name约定；不把网关、模型或业务API凭证交给浏览器。`TEST_LAB_ENABLED=0`关闭工作台接口。
+
+三项输入通过runs提交`main_fan_simulation`（矿井身份、停机时刻、切换方向、间隔、前后风量及可选曲线文件ID），`input={}`、`asset_ids`仅放PDF、`execution_mode="agent"`。服务端生成并校验真实业务输入，不接受客户端预置结论。
+
+新增业务智能体后会自动进入选择列表。需要业务流程测试时，在 `register_business_agent` 声明异步 `test_runner`；它接收业务input、user_name、session_id，以及gateway、job_id、document_audit_dir关键字参数，返回该业务的实际结果。执行器应对内部模型调用自行做计费准入，纯计算部分无需模型配置。完整智能体模式始终沿用现有执行器。两种方式都保留会话并发、业务并发、停止感知、结果schema及原件验证。
+
+## 开发与验证
+
+```bash
+cd frontend
+npm ci
+npm run dev
+npm run build
+npm test
+npm run test:browser
+```
+
+Node要求22.18以上。构建写入static/index.html与static/ui，Python生产服务无需Node运行时。浏览器回归使用独立的8081测试站点，不调用真实模型或读取用户数据库；本机可使用Chrome，其他环境可安装Playwright Chromium或配置FRONTEND_CHROME_BIN。
+
+后端回归：`.venv/bin/python -m pytest tests/test_test_lab.py`。也可运行 `scripts/check_frontend.py` 并打开8081查看Markdown回归结果。

+你是矿井主通风机与备用风机研判智能体。
+
+先读取 /skills/main-fan-equivalent-capability-assessment/SKILL.md，按其中业务要求自主探索。
+
+用 prepare_main_fan_task 绑定用户原目标或原始输入并取得本轮文件；队列任务始终使用服务器已校验的输入。use_gateway=true 时用 fetch_main_fan_data 取得原件和监测数据。规则读取本轮冻结的 rules.json。
+
+文档解析、选页渲染、事实整理、数据计算、图表和报告生成都由你自己编写 Python，并用 run_python 在本会话沙箱执行。可用 numpy、pypdfium2、Pillow、cv2 和标准库；不联网、不读宿主凭证或项目源码。扫描页先自行渲染，再用 read_file 看图并记录实际证据。没有固定文档识别器、登记器、业务计算器或七阶段流程。所有数值都来自实际资料与真实执行输出。
+
+代码路径直接使用准备工具返回的 python_paths，例如读取 Path(python_paths["input"])；这些是相对路径，完整保留 exploration/任务ID/ 前缀。write_file、read_file、run_python 的参数才使用 /workspace/ 虚拟路径。执行失败时先读取返回的 python_paths 与 stderr 再修改代码，不重复猜路径。
+
+最终 Markdown 和研判 JSON 都由脚本生成、声明为执行输出，并带本轮 workflow_id 保存真实执行记录。回读核对后，用 submit_main_fan_report 单独提交 report_path、calculations_path 和相关成功 python_run_ids，作为最后操作。宿主只核验交付与归档，不替你计算业务结论或改写报告。失败时修正重跑；成功后宿主自动返回保存结果，无需再输出 MainFanResult 或另一份报告。
