+# Proposa AI 文件检测接口对接文档
+
+版本日期：2026-09-20。适用范围：当前仓库实现。
+
+本文路径、文件名、大小和摘要均为示例，不是线上检测结果。将 `https://api.example.com`
+替换为实际服务地址。后端入库前建议采用本文的 JSON 三字段请求。
+
+## 1. 接口信息
+
+| 项目 | 说明 |
+| --- | --- |
+| 用途 | 入库前检测文件是否为有效 DOCX 或可提取文字的 PDF |
+| 请求方法 | `POST` |
+| 请求路径 | `/api/v1/files/validate` |
+| 请求格式 | `application/json`；兼容 `multipart/form-data` 单文件上传 |
+| 响应格式 | `application/json`，直接返回对象，无 `code` / `data` 外层包装 |
+| 执行方式 | 同步检测，当前请求直接返回结果，不需要轮询 |
+| 鉴权 | 当前应用不要求 token；如部署网关设置鉴权，按网关要求提供 |
+| 其他参数 | 不需要 `txbId`、`CALLBACK_URL` 或生成任务参数 |
+
+本接口只检测文件，不负责入库，不创建投标生成任务，不调用 LLM、不执行 OCR、不发送回调。
+源文件保持不变，检测副本在成功或失败后自动清理。
+
+**放行规则：仅 HTTP 200 且响应 `valid=true` 时继续入库。其他状态或网络异常均不能视为通过。**
+
+## 2. JSON 请求体
+
+```json
+{
+  "file_path": "static/file/参考投书.docx",
+  "file_role": "REFERENCE_BID",
+  "is_absolute": false
+}
+```
+
+| 字段 | 类型 | 必填 | 说明 |
+| --- | --- | --- | --- |
+| `file_path` | string | 是 | 服务端本地文件路径，不能为空；不是 HTTP URL，也不是调用方电脑上仅本机可见的路径 |
+| `file_role` | string | 是 | 业务用途，见下表；枚举值区分大小写 |
+| `is_absolute` | boolean | 是 | `true` 直接读取清理后的路径；`false` 根据业务用途拼接配置目录。必须传 JSON 布尔值，不能传字符串 `"false"` 或数字 0/1 |
+
+### 2.1 业务用途与目录
+
+| `file_role` | 业务用途 | `is_absolute=false` 时的目录 |
+| --- | --- | --- |
+| `TENDER_FILE` | 招标文件 | `TPC_DIR` |
+| `PROCUREMENT_FILE` | 采购需求 | `TPC_DIR` |
+| `CLA_FILE` | 澄清公告 | `TPC_DIR` |
+| `REFERENCE_BID` | 参考投书 | 依次查找 `REFERENCE_DIR`、`REFERENCE_DIR1` |
+
+`file_role` 是业务用途，`file_type` 是响应中的实际文件格式（`docx` / `pdf`），两者不同。
+**当前检测接口中，业务用途只决定路径解析规则，各用途均可检测 DOCX 或文字型 PDF。**
+原生成接口仍要求招标文件为文字 PDF、采购需求和参考投书为 DOCX；检测通过不代表已满足
+生成接口对应字段的格式要求。澄清公告在原生成接口中仍仅接收记录、不参与生成。
+
+### 2.2 路径解析顺序
+
+1. 去除 `file_path` 首尾空白，删除独立的 `static/` 或 `static\` 目录段。
+   `mystatic/`、文件名 `static.docx` 不受影响，配置目录本身不清理。
+2. `is_absolute=true`：按清理后的路径直接读取，不拼接业务目录。调用方应提供服务端绝对路径。
+   为兼容原接口，此模式不会额外拒绝相对文本；若误传相对路径，会按服务进程当前工作目录解析。
+3. `is_absolute=false`：去掉清理后路径开头的 `/` 或 `\`，按上表拼接配置目录。
+   即使传入路径以 `/` 开头，也不会自动改成绝对路径模式。
+4. 参考投书选择第一个实际存在的文件。两个目录都有文件时优先 `REFERENCE_DIR`；
+   第一份存在但内容不合法时，直接返回检测失败，不跳到第二份。
+5. 将选中的源路径转为完整绝对路径后检测，并在响应中返回。
+
+路径按 API 所在操作系统解释。Windows 路径建议使用 `E:/uploads/a.docx`，或在 JSON 中
+正确转义反斜杠。相对配置目录也按服务进程工作目录解析，生产环境建议配置绝对目录。
+
+示例配置（请替换为实际服务端配置）：
+
+```dotenv
+TPC_DIR=/data/tender
+REFERENCE_DIR=/data/shenqin
+REFERENCE_DIR1=/data/dms/dms_upload
+```
+
+| 请求路径 | 用途 | 模式 | 解析结果 |
+| --- | --- | --- | --- |
+| `static/file/招标文件.pdf` | `TENDER_FILE` | false | `/data/tender/file/招标文件.pdf` |
+| `/static/file/采购需求.docx` | `PROCUREMENT_FILE` | false | `/data/tender/file/采购需求.docx` |
+| `static/file/参考投书.docx` | `REFERENCE_BID` | false | 先查 `/data/shenqin/file/参考投书.docx`，未找到再查 `/data/dms/dms_upload/file/参考投书.docx` |
+| `/data/uploads/澄清公告.pdf` | `CLA_FILE` | true | `/data/uploads/澄清公告.pdf` |
+
+### 2.3 调用示例
+
+Linux / macOS Shell：
+
+```bash
+curl -X POST "https://api.example.com/api/v1/files/validate" \
+  -H "Content-Type: application/json" \
+  --data '{"file_path":"static/file/参考投书.docx","file_role":"REFERENCE_BID","is_absolute":false}'
+```
+
+PowerShell：
+
+```powershell
+$body = @{
+    file_path = "static/file/参考投书.docx"
+    file_role = "REFERENCE_BID"
+    is_absolute = $false
+} | ConvertTo-Json
+Invoke-RestMethod -Method Post `
+    -Uri "https://api.example.com/api/v1/files/validate" `
+    -ContentType "application/json; charset=utf-8" `
+    -Body ([System.Text.Encoding]::UTF8.GetBytes($body))
+```
+
+## 3. 成功响应
+
+HTTP 200，DOCX 示例：
+
+```json
+{
+  "valid": true,
+  "file_type": "docx",
+  "is_text_pdf": null,
+  "file_role": "REFERENCE_BID",
+  "resolved_path": "/data/shenqin/file/参考投书.docx",
+  "filename": "参考投书.docx",
+  "size": 12345,
+  "sha256": "0123456789abcdef0123456789abcdef0123456789abcdef0123456789abcdef",
+  "message": "文件检测通过"
+}
+```
+
+| 字段 | 类型 | 说明 |
+| --- | --- | --- |
+| `valid` | boolean | 成功时为 true |
+| `file_type` | string | `docx` 或 `pdf` |
+| `is_text_pdf` | boolean / null | PDF 成功时为 true；DOCX 为 null |
+| `file_role` | string | 请求中的业务用途，仅 JSON 路径模式返回 |
+| `resolved_path` | string | 实际选中源文件的完整路径，仅 JSON 路径模式成功时返回 |
+| `filename` | string | 文件名，不含目录 |
+| `size` | integer | 检测文件大小，单位字节 |
+| `sha256` | string | 检测内容的 SHA-256，64 位十六进制字符串 |
+| `message` | string | 展示或排查用提示语，不要按文案字符串做业务判断 |
+
+PDF 成功时 `file_type="pdf"`、`is_text_pdf=true`，其余字段规则一致。
+检测后应将同一份内容入库；文件可能被替换时，可用摘要确认内容一致。
+
+## 4. 失败响应与完整路径
+
+可处理的检测/参数错误返回非 2xx 状态码，并统一包含以下字段：
+
+| 字段 | 类型 | 说明 |
+| --- | --- | --- |
+| `valid` | boolean | false |
+| `message` | string | 失败原因；能解析路径时包含完整源路径或所有完整候选路径 |
+| `detail` | string | 与 message 相同，兼容原有读取 detail 的调用方 |
+| `resolved_path` | string / null | 只有一个已确定源路径或候选时返回该完整路径；不代表文件一定存在。多个候选或无法解析时为 null |
+| `candidate_paths` | array[string] | 本次已确定的完整源路径或未找到文件时的完整候选列表；无法解析时为空数组 |
+
+`message` 中的完整路径是清理 `static`、拼接业务目录后的服务端路径，不是用户传入的
+部分路径，也不是内部检测临时副本路径。路径分隔符以实际服务端系统为准。
+
+### 4.1 内容不合法
+
+HTTP 400：
+
+```json
+{
+  "valid": false,
+  "message": "REFERENCE_BID 不是有效的 DOCX 文件；完整文件路径：/data/shenqin/file/参考投书.docx",
+  "detail": "REFERENCE_BID 不是有效的 DOCX 文件；完整文件路径：/data/shenqin/file/参考投书.docx",
+  "resolved_path": "/data/shenqin/file/参考投书.docx",
+  "candidate_paths": ["/data/shenqin/file/参考投书.docx"]
+}
+```
+
+无文字 PDF、文件为空、文件无法读取、格式不支持、文件超限等场景同样包含完整源路径，
+具体原因和 HTTP 状态码不同。
+
+### 4.2 参考投书两个目录都未找到
+
+HTTP 400（按上文示例目录配置）：
+
+```json
+{
+  "valid": false,
+  "message": "REFERENCE_BID 在 REFERENCE_DIR 和 REFERENCE_DIR1 下均不存在: file/参考投书.docx；完整文件路径：/data/shenqin/file/参考投书.docx；/data/dms/dms_upload/file/参考投书.docx",
+  "detail": "REFERENCE_BID 在 REFERENCE_DIR 和 REFERENCE_DIR1 下均不存在: file/参考投书.docx；完整文件路径：/data/shenqin/file/参考投书.docx；/data/dms/dms_upload/file/参考投书.docx",
+  "resolved_path": null,
+  "candidate_paths": [
+    "/data/shenqin/file/参考投书.docx",
+    "/data/dms/dms_upload/file/参考投书.docx"
+  ]
+}
+```
+
+只配置了一个参考目录时，仅列出该目录对应的候选路径。
+
+### 4.3 无法确定完整路径
+
+例如相对模式未配置 `TPC_DIR`，HTTP 400：
+
+```json
+{
+  "valid": false,
+  "message": "TENDER_FILE 为相对路径，但未配置 TPC_DIR",
+  "detail": "TENDER_FILE 为相对路径，但未配置 TPC_DIR",
+  "resolved_path": null,
+  "candidate_paths": []
+}
+```
+
+必填参数缺失、业务用途无效、JSON 格式错误等发生在路径解析之前，也无法提供完整路径；
+服务会明确返回原因，不会猜测配置目录或虚构文件路径。
+
+## 5. HTTP 状态码
+
+| 状态码 | 含义及处理 |
+| --- | --- |
+| 200 | 检测通过；确认 valid=true 后继续入库 |
+| 400 | 文件不存在/无法读取/为空、后缀或内容无效、PDF 加密或无文字、路径配置缺失、JSON 语法错误等；读取 message 排查 |
+| 413 | 超过 `PROPOSA_API_MAX_UPLOAD_MB` 文件大小限制 |
+| 415 | 请求 Content-Type 不是 application/json 或 multipart/form-data |
+| 422 | JSON 三个必填字段缺失/类型不正确/用途无效，或上传字段缺失、不是文件、上传多个文件 |
+
+网络异常、网关错误或未处理的服务异常（例如 HTTP 500）不能视为检测通过；这些响应不保证
+包含本接口的 JSON 字段。建议保存 HTTP 状态码和响应正文，若存在 `message` 优先展示它。
+
+## 6. 检测范围与限制
+
+- 文件后缀仅允许 `.docx`、`.pdf`，不区分大小写；同时检查实际内容，不只检查后缀或 MIME。
+- DOCX 检查 ZIP 容器、必需 OOXML 部件、主文档内容类型、包关系及正文 XML；
+  改后缀的旧版 `.doc`、普通 ZIP、无效主文档会被拒绝。DOCX 不要求包含文字。
+- PDF 必须未加密、可逐页解析，并至少一页可提取非空文字；纯扫描或无文字 PDF 不通过。
+- 混合文字/扫描页 PDF、有 OCR 文字层的 PDF 可能通过；不保证每页都有文字，
+  不判断 OCR 正确率，也不判断业务内容是否完整。
+- 文件大小沿用 `PROPOSA_API_MAX_UPLOAD_MB`，默认 512 MB；JSON 本地路径也受此限制。
+  PDF 检测会读入内存，服务端应按容量设置上限。
+- 后续生成接口仍会再次校验文件。本接口通过不保证后续 Step1-6 一定成功。
+
+## 7. 兼容的文件上传方式
+
+无需服务端文件路径时，可使用 `multipart/form-data` 上传一个小写 `file` 字段。
+该模式不需要 `file_path`、`file_role`、`is_absolute`，不参与业务目录拼接。
+
+```bash
+curl -X POST "https://api.example.com/api/v1/files/validate" -F "file=@待检测文件.pdf"
+```
+
+成功字段与第 3 节相同，但不包含 `file_role` 和 `resolved_path`。
+失败使用第 4 节的统一结构；由于不存在服务端源路径，`resolved_path=null`、
+`candidate_paths=[]`，message 仅包含失败原因，不暴露内部临时路径。
+
+## 8. 后端接入顺序
+
+1. 将待检测文件放入 API 服务能够读取的存储位置。
+2. 根据文件业务用途发送 JSON 三字段请求，等待同步响应。
+3. HTTP 200 且 valid=true：继续业务入库；需要时保存 file_type、size、sha256。
+4. 其他响应：阻止入库，记录并展示 message；完整路径可直接用于核对目录、文件名及权限。
+5. 修正文件或路径配置后重新检测。检测和入库之间应保持文件内容一致。
+
+服务部署后可在 `/docs` 试用接口，`/openapi.json` 提供机器可读的请求契约。

+# Proposa AI 任务进度查询接口对接文档
+
+版本日期：2026-09-09。适用范围：当前仓库 API 实现。
+
+本文中的响应为按实现整理的示例，时间、错误场景和业务 ID 均为示意，**不是对任务 `b429d8ddce344f2fadac91195aa56d97` 的线上查询结果**。服务地址请替换为实际部署地址。
+
+## 1. 接口信息
+
+| 项目 | 说明 |
+| --- | --- |
+| 用途 | 查询投标文件生成任务的 Step1–6 步骤进度 |
+| 方法 | `GET` |
+| 路径 | `/api/v1/jobs/{request_id}/progress` |
+| 本次任务路径 | `/api/v1/jobs/b429d8ddce344f2fadac91195aa56d97/progress` |
+| 路径参数 | 路径中的 ID 可以是提交后返回的 `request_id`，也可以是请求中的 `txbId` 值；字符串，必填 |
+| Query / Body | 无 |
+| 响应格式 | `application/json`，直接返回对象，没有 `code` / `data` 外层包装 |
+| 鉴权 | 当前应用代码未要求 token；若部署网关设置鉴权，按网关要求提供 |
+
+请求示例（将 `https://api.example.com` 替换为实际地址）：
+
+```bash
+curl "https://api.example.com/api/v1/jobs/b429d8ddce344f2fadac91195aa56d97/progress" -H "Accept: application/json"
+```
+
+**对接核心规则：`/progress` 是步骤快照，最终成功或失败必须查询 `GET /api/v1/jobs/{request_id}` 的 `status`。HTTP 200 仅表示查询成功，不表示生成成功。**
+
+### 1.1 使用 txbId 查询最新任务
+
+状态、进度、下载三个接口共用同一套 ID 解析规则。假设提交时传入 `"txbId": "TEST-TXB-001"`，可直接请求：
+
+```text
+GET /api/v1/jobs/TEST-TXB-001
+GET /api/v1/jobs/TEST-TXB-001/progress
+GET /api/v1/jobs/TEST-TXB-001/file
+```
+
+无需增加 `?txbId=` 查询参数，也不需要请求体。提交参数名仍是大小写准确的 `txbId`。
+
+- 优先精确匹配 `request_id`，找不到时再按 `txbId` 找最新任务。如果某个 `txbId` 恰好与已有 `request_id` 相同，优先返回该 `request_id` 对应任务。
+- 同一个 `txbId` 每次提交仍产生新的唯一 `request_id` 和独立文件目录；映射指向最近提交的任务，不按完成时间排序。并发请求按服务端校验后注册任务的顺序确定先后。
+- 新任务排队、处理中或处理失败时，不会回退到之前的成功任务；新任务未完成时用 `txbId` 下载仍返回 409。
+- 请求校验失败或后台提交失败（未成功接收的请求），不替换之前有效的映射。
+- 历史任务通过原有 `request_id` 查询。查询状态响应中的 `request_id`、提交响应和回调中的 ID、下载 URL 仍使用真正的任务 ID，不替换为 `txbId`。
+- ID 值区分大小写。提交时 `txbId` 首尾空白会被去除；查询应使用处理后的值。本文 URL 示例使用可直接放入路径的 ID。
+
+**如果要保证状态、进度、下载对应同一次生成：先通过 `txbId` 查询任务状态，拿到响应中的 `request_id`，后续固定使用该 ID。** 否则在两次请求之间有同一 `txbId` 的新任务提交时，最新任务可能发生切换。
+
+## 2. 进度响应字段
+
+有步骤快照时返回以下字段；无快照时仅返回 `status`、`message`，其余字段缺省。
+
+| 字段 | 类型 | 含义 |
+| --- | --- | --- |
+| `updated_at` | string | 快照最后更新时间，ISO 8601，UTC，如 `2026-09-09T02:30:00+00:00`；北京时间需加 8 小时 |
+| `current_step` | integer | 当前或最近完成的步骤编号，1–6 |
+| `total_steps` | integer | 总步骤数，当前固定为 6 |
+| `current_step_name` | string | 步骤名称 |
+| `status` | string | 有快照时为 `running` 或 `completed`；无快照时回退为任务状态，见后文 |
+| `message` | string | 展示提示语，不应作为程序判断条件 |
+| `completed_steps` | integer[] | 已执行完成的步骤编号；正在执行的步骤不包含在其中 |
+
+此接口不返回 `request_id`、`txbId`、`error`、`resultPath`、下载地址或 `progress_url`。调用方需保存提交时获得的任务 ID。
+
+| 步骤 | `current_step_name` |
+| --- | --- |
+| 1 | Step 1 文档解析及表/函/表格提取 |
+| 2 | Step 2 招标需求、评分项、废标项分析 |
+| 3 | Step 3 投书大纲生成 |
+| 4 | Step 4 章节内容生成与模板填充 |
+| 5 | Step 5 覆盖性、风险与完整性审核修复 |
+| 6 | Step 6 最终 DOCX 聚合装配 |
+
+## 3. 处理中拿到的结果
+
+### 3.1 尚未产生步骤快照
+
+HTTP 200，排队时可能返回：
+
+```json
+{
+  "status": "queued",
+  "message": "任务已排队或尚未开始"
+}
+```
+
+后台已启动但尚未写入有效快照时：
+
+```json
+{
+  "status": "processing",
+  "message": "任务已排队或尚未开始"
+}
+```
+
+调用方显示“排队中”或“处理中”并继续轮询；不要强制读取此时不存在的 `current_step`、`completed_steps`。
+
+### 3.2 正在执行某一步骤
+
+HTTP 200，例如正在执行 Step3：
+
+```json
+{
+  "updated_at": "2026-09-09T02:30:00+00:00",
+  "current_step": 3,
+  "total_steps": 6,
+  "current_step_name": "Step 3 投书大纲生成",
+  "status": "running",
+  "message": "Step 3 投书大纲生成 正在处理",
+  "completed_steps": [1, 2]
+}
+```
+
+含义：Step1、Step2 已完成，Step3 正在执行。仍需查询任务状态确认任务没有失败，原因见第 4 节。
+
+### 3.3 某一步骤刚完成，但任务仍在处理
+
+HTTP 200，例如 Step3 刚完成、Step4 尚未更新快照：
+
+```json
+{
+  "updated_at": "2026-09-09T02:35:00+00:00",
+  "current_step": 3,
+  "total_steps": 6,
+  "current_step_name": "Step 3 投书大纲生成",
+  "status": "completed",
+  "message": "Step 3 投书大纲生成 处理完成",
+  "completed_steps": [1, 2, 3]
+}
+```
+
+这里的 `completed` 仅表示 Step3 完成，**不能停止轮询或提示整个任务完成**。
+
+## 4. 处理失败拿到的结果
+
+### 4.1 已产生快照后失败：进度可能仍为 running
+
+当前实现失败时不会把步骤快照改写为 `failed`。例如 Step4 执行失败，`/progress` 仍可能返回 HTTP 200 和以下最后快照：
+
+```json
+{
+  "updated_at": "2026-09-09T02:40:00+00:00",
+  "current_step": 4,
+  "total_steps": 6,
+  "current_step_name": "Step 4 章节内容生成与模板填充",
+  "status": "running",
+  "message": "Step 4 章节内容生成与模板填充 正在处理",
+  "completed_steps": [1, 2, 3]
+}
+```
+
+此时查询任务状态接口：
+
+```bash
+curl "https://api.example.com/api/v1/jobs/b429d8ddce344f2fadac91195aa56d97"
+```
+
+该接口 HTTP 200 响应中的关键字段如下（**仅摘录字段，不是完整响应**）：
+
+```json
+{
+  "request_id": "b429d8ddce344f2fadac91195aa56d97",
+  "txbId": "TEST-TXB-001",
+  "status": "failed",
+  "error": "Step1-6 处理进程异常退出（退出码 1）",
+  "callback_delivered": true
+}
+```
+
+调用方以任务 `status=failed` 判定失败，停止轮询，展示 `error`，隐藏下载入口。失败原因可能是“处理超时”、进程异常退出或其他错误文本，不能仅匹配某个固定错误字符串。
+
+`callback_delivered=true` 只说明结果回调已按 HTTP 状态成功投递，不表示生成成功。回调失败也不改变生成结果；可查看任务的 `callback_error`。
+
+### 4.2 未产生有效快照就失败
+
+`/progress` 可返回 HTTP 200：
+
+```json
+{
+  "status": "failed",
+  "message": "任务已排队或尚未开始"
+}
+```
+
+此处 `message` 是统一兜底文案，并非真实失败原因。仍需从任务状态接口读取 `error`。
+
+### 4.3 全部步骤完成后，最终文件校验或发布失败
+
+此时 `/progress` 甚至可能仍是 Step6 的 `completed` 快照，而任务状态接口返回 `failed`。最终结果仍以任务状态为准。
+
+注意：失败回调里的 `resultPath="error: ..."` 属于回调协议；`/progress` 不返回该字段，任务状态查询也不自动构造该字段。任务查询中如有 `output_path`，它只是预定输出路径，不能据此判成功。
+
+## 5. 处理完成拿到的结果
+
+步骤全部执行完成后，`/progress` 返回 HTTP 200：
+
+```json
+{
+  "updated_at": "2026-09-09T03:20:00+00:00",
+  "current_step": 6,
+  "total_steps": 6,
+  "current_step_name": "Step 6 最终 DOCX 聚合装配",
+  "status": "completed",
+  "message": "Step 6 最终 DOCX 聚合装配 处理完成",
+  "completed_steps": [1, 2, 3, 4, 5, 6]
+}
+```
+
+再查询任务状态接口，成功时关键字段如下（**仅摘录字段，不是完整响应**；文件名及路径为虚构示例）：
+
+```json
+{
+  "request_id": "b429d8ddce344f2fadac91195aa56d97",
+  "txbId": "TEST-TXB-001",
+  "status": "completed",
+  "output_path": "/srv/proposa/output/api_jobs/b429d8ddce344f2fadac91195aa56d97/示例招标文件.docx",
+  "final_review_path": "/srv/proposa/output/api_jobs/b429d8ddce344f2fadac91195aa56d97/示例招标文件.docx",
+  "final_review_url": "https://api.example.com/api/v1/jobs/b429d8ddce344f2fadac91195aa56d97/file",
+  "callback_delivered": true,
+  "callback_error": ""
+}
+```
+
+只有任务 `status=completed` 才展示“生成完成”和下载按钮。`final_review_path` / `output_path` 是服务器路径，浏览器不能直接打开；通过下载接口获取文件：
+
+```bash
+curl "https://api.example.com/api/v1/jobs/b429d8ddce344f2fadac91195aa56d97/file" --output "投标文件.docx"
+```
+
+下载成功：HTTP 200，响应为 DOCX 二进制，Content-Type 为 `application/vnd.openxmlformats-officedocument.wordprocessingml.document`，不是 JSON。
+
+Step6 完成后还有文件检查、发布和回调投递过程；当前实现等回调尝试结束才更新任务终态。因此短暂出现“进度 Step6 completed、任务 processing”时，应继续等待。回调最终失败仍可得到任务 `completed`，但 `callback_delivered=false`。
+
+## 6. 异常响应和任务保留
+
+| 请求 | HTTP 状态 | 含义与处理 |
+| --- | --- | --- |
+| `/progress`、任务查询、下载 | 404 | 任务不存在；核对任务 ID 和服务实例，不应当作生成失败原因 |
+| 下载 `/file` | 409 | 任务未完成，或最终文件不存在；不可按 DOCX 保存响应 |
+| 查询 | 网络异常 / 5xx | 本次查询失败，不等于任务生成失败；提示重试，避免直接把业务任务改为 failed |
+
+404 响应：
+
+```json
+{
+  "detail": "任务不存在"
+}
+```
+
+下载 409 响应：
+
+```json
+{
+  "detail": "任务尚未生成可下载文件"
+}

+任务记录及 `txbId → 最新 request_id` 映射当前保存在 API 进程内存中，服务重启后旧 ID 或 txbId 可能返回 404，即使磁盘文件还在。多实例部署需确保查询访问持有该任务记录及映射的实例。
+
+默认清理中间文件时，会先将末次步骤快照保存在任务内存记录中，再清理中间目录。因此同一进程内，处理中间文件清理后仍可查询末次快照；该快照不会因清理自动变成成功或失败状态。
+
+## 7. 推荐对接流程
+
+1. 提交任务后保存 `request_id`，与自己的业务 `txbId` 关联；也可直接用 `txbId` 查询最新任务，再从任务状态响应取实际 `request_id`。
+2. 建议每 3–5 秒查询一次任务状态；当状态为 `queued` 或 `processing` 时，同时查询 `/progress` 更新步骤展示。这是调用建议，服务端没有强制该轮询间隔。
+3. 任务状态为 `failed`：停止轮询，展示 `error`，不提供下载。
+4. 任务状态为 `completed`：停止轮询，提供 `/file` 下载；下载仍需检查 HTTP 状态。
+5. 两个查询不是同一时刻的原子快照，发生矛盾时以任务终态优先；未知字段可以忽略，未知状态保留重试和异常提示。
+
+判定逻辑示意：
+
+```text
+job = GET /api/v1/jobs/{request_id}
+如果查询失败：处理 HTTP/网络异常
+否则如果 job.status == failed：展示 job.error，结束轮询
+否则如果 job.status == completed：展示完成及下载按钮，结束轮询
+否则：
+    progress = GET /api/v1/jobs/{request_id}/progress
+    若有步骤字段：显示当前步骤和已完成步骤
+    否则：显示排队中或处理中
+    等待后继续查询 job
+```
+
+接口没有提供百分比或预计剩余时间。可显示“已完成 2/6 步”；各步骤耗时不同，不宜将步骤比例当作实际耗时百分比。`updated_at` 仅在步骤开始或结束时更新，长时间不变化本身不能证明失败。
+
+对接验收至少覆盖：两种 ID 的三个查询接口、同一 txbId 重复提交后最新任务切换及历史任务可查、提交失败不污染映射、排队无步骤字段、步骤 running、中间步骤 completed、失败但进度仍 running、Step6 completed 但任务仍 processing、任务 completed 后下载，以及 404/409。

+
+JSON 请求包含三个必填字段：
+
+```json
+{
+  "file_path": "static/file/参考投书.docx",
+  "file_role": "REFERENCE_BID",
+  "is_absolute": false
+}
+```
+
+| 字段 | 说明 |
+| --- | --- |
+| `file_path` | 非空字符串，服务端文件路径，不是 HTTP 下载地址。 |
+| `file_role` | `TENDER_FILE` 招标文件、`PROCUREMENT_FILE` 采购需求、`CLA_FILE` 澄清公告、`REFERENCE_BID` 参考投书。 |
+| `is_absolute` | 必填布尔值；true 直接读取清理后的路径，false 按业务用途拼接目录。 |
+
+路径规则与原生成接口共用：先清理独立 `static` 目录段；相对模式下，前三类拼接
+`TPC_DIR`，参考投书依次在 `REFERENCE_DIR`、`REFERENCE_DIR1` 下查找，首个存在文件优先。
+成功响应额外包含 `file_role` 和 `resolved_path`（实际完整源文件路径）。业务用途决定
+路径规则；本检测接口允许各用途的有效 DOCX 或文字 PDF，生成接口的业务字段格式限制仍保留。
+
+失败仍返回非 2xx HTTP 状态，包含顶层 `valid=false`、`message`、兼容字段 `detail`、
+`resolved_path` 和 `candidate_paths`。文件不存在、损坏、无文字、超限或无法读取时，
+`message` 包含解析后的完整源路径，不返回检测临时副本路径。例如：

+  "message": "REFERENCE_BID 不是有效的 DOCX 文件；完整文件路径：/data/shenqin/file/参考投书.docx",
+  "detail": "REFERENCE_BID 不是有效的 DOCX 文件；完整文件路径：/data/shenqin/file/参考投书.docx",
+  "resolved_path": "/data/shenqin/file/参考投书.docx",
+  "candidate_paths": ["/data/shenqin/file/参考投书.docx"]
+}
+```
+
+参考投书所有配置目录均未找到文件时，`message` 和 `candidate_paths` 列出所有完整候选路径，
+多个候选时 `resolved_path=null`。参数无效或目录未配置、无法确定完整路径时，明确返回原因，
+不虚构完整路径（`resolved_path=null`、`candidate_paths=[]`）。
+
+multipart 模式仍使用小写 `file` 上传；该模式无服务端源路径，失败不返回临时路径：
+
+```powershell
+curl.exe -X POST "http://127.0.0.1:8000/api/v1/files/validate" -F "file=@待上传文件.pdf"
