+
+当前仓库里 `yuanzhipeng` 共有 4 个提交：
+
+| 提交 | 日期 | 所在分支 | 标题 |
+| --- | --- | --- | --- |
+| `a926ee6` | 2026-06-25 | `main`, `origin/main`, `origin/HEAD` | `chore(build): 更新.gitignore配置和清理Wails临时文件` |
+| `1517be2` | 2026-06-26 | `origin/develop` 历史 | `feat(auto-reply): 接入万川平台模型配置 + 各模型独立网关回退` |
+| `849090a` | 2026-06-26 | `origin/develop` 历史 | `feat(auto-reply): 优化自动回复逻辑和知识库功能` |
+| `1ca66dc` | 2026-06-26 | `origin/develop` | `docs(batch): 更新批处理脚本注释` |
+
+需要注意：当前 `main/origin/main` 只包含 `a926ee6`；后续 3 个功能提交目前在 `origin/develop` 上。
+
+按 `a926ee6^..1ca66dc` 汇总，整体变更约为：
+
+- 51 个文件变化
+- 2922 行新增
+- 1299 行删除
+- 删除旧备份文件 `helper/auto_reply_ai.go.bak`
+- 删除 Wails 构建生成文件 `build/windows/installer/wails_tools.nsh`
+
+## 2. 主要完善内容
+
+### 2.1 万川平台模型配置接入
+
+相关提交：`1517be2`
+
+新增了万川平台配置能力，让自动回复模块可以从万川平台拉取模型配置并自动回填到本地 AI 配置。
+
+主要内容：
+
+- 新增后端接口文件 `wanchuan_proxy.go`：
+  - `WanchuanLogin`：登录万川平台并获取 token。
+  - `WanchuanGetModel`：按模型 code 获取模型配置。
+  - `GetPlatformConfig` / `SavePlatformConfig`：读取和保存平台账号配置。
+  - 日志中对密码、token、apiKey 做脱敏处理。
+- 配置结构新增 `PlatformConfig`，用于保存万川平台地址、账号、密码。
+- 前端 `AutoReply.vue` 新增“万川平台”配置卡片：
+  - 填写平台地址、账号、密码。
+  - 一键“登录并获取模型”。
+  - 自动拉取 chat、vision、embedding、rerank、voice 等用途模型。
+  - 将模型名、网关地址、API Key 回填到自动回复配置。
+- 前端 Wails 绑定新增：
+  - `GetPlatformConfig`
+  - `SavePlatformConfig`
+  - `WanchuanLogin`
+  - `WanchuanGetModel`
+
+### 2.2 各类模型支持独立网关和独立 Key
+
+相关提交：`1517be2`
+
+完善了自动回复中不同模型的配置拆分，避免所有能力都被迫共用同一个文本模型网关。
+
+主要内容：
+
+- `RetrievalConfig` 新增：
+  - `embeddingBaseUrl`
+  - `embeddingApiKey`
+  - `rerankBaseUrl`
+  - `rerankApiKey`
+- Embedding 和 Rerank 调用优先使用各自独立配置，未配置时才回退到主 AI 网关。
+- 非 DashScope 网关下，视觉模型不再强行写死为 DashScope 的默认视觉模型。
+- 万川统一网关场景下，视觉模型可动态复用聊天模型；如果平台提供独立 vision 配置，则使用独立 vision 网关。
+- 当 embedding 模型或维度变化时，会识别旧向量索引已经属于不同向量空间，并提示或触发重建，避免旧索引造成检索异常。
+
+### 2.3 自动回复上下文逻辑优化
+
+相关提交：`849090a`
+
+优化了客户追问、换话题和上下文拼接逻辑，减少模型被历史对话带偏的问题。
+
+主要内容：
+
+- 新增 `contextPromptForQuestion`：
+  - 只有“它多少钱”“刚才那个再说说”“继续”等指代型追问才注入历史上下文。
+  - “今天星期几”“你们有什么产品”等自包含问题不再携带上一轮话题。
+- 新增换话题识别：
+  - 如“换个话题吧”“聊点别的”“不聊这个了”会直接回复引导语。
+  - 如果“换个话题，你们产品多少钱”这类句子带了新问题，则继续正常处理新问题。
+- Prompt 中强调上下文只用于理解称呼和承接，不应主动延续旧话题。
+- 默认回复详细度从 `detailed` 调整为 `medium`，避免自动回复过长、太像模板。
+
+### 2.4 知识库索引与向量检索增强
+
+相关提交：`849090a`, `1517be2`
+
+修复和增强了知识库扫描、向量索引、重排调用等流程。
+
+主要内容：
+
+- 知识库重建从只扫描根目录改为递归扫描子目录。
+  - 适配 `01_产品/数控机床/xxx.md`、`03_售后/故障排查/xxx.md` 这类分类目录。
+- 重建知识库后，前端会显示扫描文件数、分片数、失败文件数。
+  - 如果 0 个文件被扫描到，会给出明显提示。
+- 向量索引加载时检测模型名和维度是否与当前配置一致。
+  - 不一致时清空陈旧向量，回退关键词检索，并提示重建索引。
+- Embedding/Rerank 请求支持独立 Base URL 和 API Key。
+
+### 2.5 素材库扫描、匹配和开场白生成
+
+相关提交：`a926ee6`, `849090a`
+
+完善了素材库能力，尤其是目录化素材、误匹配控制和 AI 自动生成素材发送话术。
+
+主要内容：
+
+- 新增大量示例素材到 `config/materials`，包括：
+  - 产品图片
+  - 宣传海报
+  - 工作流图
+  - 教程截图
+  - 案例展示
+  - 联系方式卡片
+- 素材扫描从根目录扫描改为递归扫描子目录。
+- 素材路径保存为相对路径，并统一使用 `/` 分隔。
+- 子目录名也会加入关键词，方便按分类命中素材。
+- 新增 `CaptionSource` 字段，区分素材话术来源：
+  - `manual`：人工维护，重新同步时不覆盖。
+  - `ai`：AI 生成，已有时不重复生成。
+  - 空值：历史数据或默认话术，可按需生成。
+- 新增 `helper/auto_reply_material_caption.go`：
+  - 图片使用视觉模型生成一句自然开场白。
+  - 视频按标题生成。
+  - 文档尝试抽取开头内容后概括。
+  - 生成结果会去引号、压缩换行、过滤 `NO_ANSWER`、限制长度。
+- 素材匹配新增“强信号”门槛。
+  - 只有整词关键词、问句模板、完整标题或文件名命中才会发送素材。
+  - 仅靠 2-gram 模糊片段命中不会触发发送，减少误发资料。
+
+### 2.6 媒体消息诊断和类型识别修复
+
+相关提交：`849090a`
+
+增强了企业微信媒体消息回调的识别和诊断能力。
+
+主要内容：
+
+- 修正 `rawTypeFromEvent` 对企业微信事件类型的判断。
+  - 优先使用 DLL 真实 `event` 字段。
+  - `content_type` 只作为模拟事件或旧版本 DLL 的 fallback。
+- 避免文本消息被误判成图片，导致错误触发图片识别。
+- 新增媒体字段为空时的诊断日志。
+  - 仅在图片、视频、链接等媒体消息且 URL、本地路径、FileID 全空时记录。
+  - 日志只记录媒体相关字段，避免泄露聊天内容。
+
+### 2.7 构建、开发和打包流程完善
+
+相关提交：`a926ee6`, `1ca66dc`
+
+对 Windows/Wails 的开发和打包流程做了明显增强。
+
+主要内容：
+
+- `.gitignore` 增加构建输出、绿色免安装包、Wails 临时文件、WebView2 安装包等忽略规则。
+- 删除 `build/windows/installer/wails_tools.nsh` 这类 Wails 自动生成文件，避免把临时产物提交进仓库。
+- 新增 `scripts/dev.ps1`：
+  - 自动定位 Go/Wails。
+  - 自动安装前端依赖和 Go 模块。
+  - 编译 32 位 GUI 子系统的 `helper.exe`。
+  - 同步 DLL、`eventdata`、`requestdata` 到运行目录。

+- 新增 `scripts/build.ps1`：
+  - 构建 helper、silkdecode、主程序。
+  - 输出带时间戳的绿色免安装版目录。
+  - 写入默认配置文件和空素材索引。
+- 改进 `scripts/package-windows.ps1`：
+  - 自动探测 NSIS 标准安装路径。
+  - gcc 缺失时跳过 silkdecode，而不是直接失败。
+  - 前端构建和 Wails NSIS 构建改为按退出码判断。
+  - 安装包文件名增加时间戳。
+- 新增 `install-nsis.ps1`。
+- 新增根目录批处理：
+  - `启动开发.bat`
+  - `打包.bat`
+- `1ca66dc` 对这两个 `.bat` 的注释做了英文化和简化。
+
+### 2.8 主程序退出稳定性修复
+
+相关提交：`a926ee6`
+
+修复 Windows 下关闭主程序时可能因 helper 进程处理方式触发崩溃的问题。
+
+主要内容：
+
+- `main.go` 中 Windows 平台优先使用 Windows API 终止 helper。
+- 终止后直接返回，不再继续走通用 `Signal/Kill` 分支。
+- 避免 Go 1.25+ 中手工构造的 `os.Process` 因句柄模式无效触发 panic。
+
+### 2.9 测试覆盖增加
+
+相关提交：`1517be2`, `849090a`
+
+补充了多个回归测试，主要覆盖自动回复和配置默认值。
+
+新增或扩展的测试点包括：
+
+- 非 DashScope 网关下视觉模型跟随聊天模型。
+- DashScope 仍保留默认视觉模型兜底。
+- 知识库递归扫描子目录。
+- 素材模糊弱命中不应误发。
+- 素材开场白生成、清洗、保留人工话术。
+- 自动回复上下文只在指代追问时使用。
+- 换话题句子的识别。

+
+## 4. 总结
+
+整体来看，`yuanzhipeng` 的提交主要完善了 4 条主线：
+
+1. **万川平台接入**：从平台登录、拉模型、保存配置到前端一键回填，形成了完整闭环。
+2. **自动回复质量提升**：处理追问、换话题、回复长度、知识库完整性和媒体消息诊断，减少答非所问和误判。
+3. **知识库/素材库能力增强**：支持目录化管理、递归扫描、向量索引一致性检查、素材自动开场白和误发控制。
+4. **开发与交付流程完善**：新增一键开发/打包脚本，优化 NSIS、Wails、helper、DLL、运行资源同步，降低 Windows 环境下的构建和运行成本。
+
+如果按“是否已进主分支”看，目前只有 `a926ee6` 在 `main`；万川接入和自动回复深度优化主要还在 `origin/develop`。

+# 本地改动说明（对比 origin/develop）
+
+生成时间：2026-06-29  
+本地分支：`develop`  
+对比基准：`origin/develop`  
+远程仓库：`https://git.lzwcai.com/ly1213/qiweimanager-master.git`
+
+> 说明：本文只梳理当前工作区相对 Git 远程基线的本地改动，未提交 Git，也未改动远程仓库。
+
+## 一、改动概览
+
+本次本地改动主要围绕自动客服、素材发送、知识库重建提示和安装包资源打包四块：
+
+1. 新增“只回复外部客户”开关，开启后企业内部成员消息会被自动忽略，不再触发 AI 回复或转人工。
+2. 优化素材发送逻辑，支持按素材子文件夹命中问题场景，显式要求“全部”时才发送该匹配文件夹内全部素材。
+3. 优化素材话术和发送顺序，统一使用“您”，并在发送图片/视频/动图后补充描述；发送文件时携带文件名，便于企微侧展示。
+4. 命中素材时会把知识库中相关文字说明整理后一起发送，更接近真实客服“先说明、再发资料/或发完资料补描述”的场景。
+5. 优化知识库重建错误提示：重建成功后清除旧的知识库错误；向量索引失败时保留明确错误和扫描统计。
+6. 优化 Windows 安装包打包，把 `tools` 目录、PDF 渲染依赖 DLL、语音转码工具等运行资源纳入安装包。
+
+## 二、功能改动明细
+
+### 1. 只回复外部客户
+
+- 配置结构新增 `identity.replyExternalOnly`，默认值为 `false`，保持原有行为不变。
+- 前端“监听策略”区域新增开关：`只回复外部客户，忽略企业内部成员`。
+- 后端处理消息时，在身份识别完成后判断：
+  - 开关关闭：按原逻辑处理内部/外部/未知身份。
+  - 开关开启且识别为内部成员：直接忽略消息，记录原因为 `internal_ignored_external_only`。
+
+涉及文件：
+
+- `config/types.go`
+- `frontend/src/components/AutoReply.vue`
+- `frontend/src/main.js`
+- `helper/auto_reply.go`
+- `helper/auto_reply_test.go`
+
+### 2. 素材按文件夹/场景匹配发送
+
+- 去掉了原先“全部资料”这类泛化请求直接短路的粗粒度逻辑，改为更细的判断：
+  - 用户只说“全部资料/全部文件”，但没有明确具体场景、文件夹或素材关键词时，不自动群发，仍走澄清/普通回复，避免误发大量资料。
+  - 用户带有明确场景或文件夹关键词，例如“0505尾部切刀的资料全部发我”，会发送匹配文件夹内的全部素材。
+  - 用户明确要求某类素材，例如“全部视频/全部图片”，会按类型收集对应素材。
+- “资料/文件”不再默认只理解成普通文件；只有出现 `文档、表格、手册、说明书、ppt、pdf、doc、docx、xls、xlsx` 等明确文档词时，才限制为普通文件类型。
+
+涉及文件：
+
+- `helper/auto_reply_materials.go`
+- `helper/auto_reply_test.go`
+
+### 3. 素材发送话术与顺序
+
+- 默认话术从“发你”改为“发给您”，包括图片、视频、动图、文件和组合素材话术。
+- AI 生成素材开场白的 prompt 增加要求：必须使用“您”。
+- 命中素材后，会先从知识库命中片段中整理最多 3 条文字说明，作为“相关排查说明”发送给客户。
+- 发送顺序调整：
+  - 普通文件：先发说明话术，再发文件。
+  - 图片/视频/动图：先发素材，再发描述文字，使描述更像跟在图片或视频下面。
+- 示例素材索引里的 caption 也同步改成“发给您”。
+
+涉及文件：
+
+- `helper/auto_reply_material_caption.go`
+- `helper/auto_reply_materials.go`
+- `config/materials/materials.json`
+- `helper/auto_reply_test.go`
+
+### 4. 文件消息展示文件名
+
+- 普通文件消息 `type=11031` 发送时，额外传入文件名字段：
+  - `fileName`
+  - `file_name`
+- 文件名从实际路径 `filepath.Base(path)` 提取。
+- `requestdata/sendVWorkFileMessage.json` 同步增加文件名占位符，便于底层请求模板使用。
+
+涉及文件：
+
+- `helper/auto_reply_materials.go`
+- `requestdata/sendVWorkFileMessage.json`
+
+### 5. 知识库重建提示与错误状态
+
+- 知识库重建接口在失败时也返回已扫描到的统计信息，包括耗时、文件数、分片数和失败文件列表，方便前端展示。
+- 关键词模式下不强制重建向量索引。
+- 混合/向量模式下，如果 embedding 重建失败，会返回已扫描的知识库索引并保留知识库错误。
+- 知识库重建成功后，会清除旧的知识库错误，避免前端一直显示历史失败信息。
+- 前端 section alert 支持 `success / warn / error` 三种类型，成功提示会自动清掉对应区域旧错误。
+
+涉及文件：
+
+- `helper/auto_reply_http.go`
+- `helper/auto_reply_knowledge.go`
+- `helper/auto_reply_status.go`
+- `helper/auto_reply_knowledge_test.go`
+- `frontend/src/components/AutoReply.vue`
+
+### 6. 安装包运行资源打包
+
+- NSIS 安装脚本新增复制 `$INSTDIR\tools`，安装后会带上运行工具目录。
+- 打包脚本复制 `pdftoppm.exe` 时，会同步复制同目录 DLL，避免部署环境缺 DLL 导致 PDF 解析不可用。
+- 打包阶段将 `tools\pdf` 整个目录同步进 NSIS runtime。
+- 当前本地已生成的新安装包中包含语音转码工具 `silkdecode.exe`。
+
+涉及文件：
+
+- `build/windows/installer/project.nsi`
+- `scripts/package-windows.ps1`
+
+最新本地安装包：
+
+`build/bin/qiweimanager-amd64-installer_20260629_145726.exe`
+
+## 三、测试与验证情况
+
+本地新增/调整的自动化测试覆盖了以下场景：
+
+- 开启“只回复外部客户”后，内部成员消息不会触发回复，并记录忽略原因。
+- 普通场景素材请求遵守 `maxPerReply` 限制。
+- 明确要求某个匹配文件夹“全部资料”时，会发送该文件夹下全部素材。
+- 泛化“全部资料都发我”不会直接群发。
+- 素材默认话术统一改为“发给您”。
+- 命中素材时，会把知识库相关说明与素材一起发送。
+- 知识库重建成功后清除旧错误；embedding 失败时保留知识库错误并返回扫描结果。
+
+建议开发同事复核时运行：
+
+```powershell
+go test ./helper ./config
+npm.cmd --prefix frontend run build
+```
+
+如果需要验证安装包资源，请重点检查安装目录下是否存在：
+
+```text
+tools/audio/silkdecode.exe
+tools/pdf/pdftoppm.exe
+```
+
+## 四、注意事项
+
+- 当前工作区还有 Wails 构建生成文件的差异痕迹，主要是 `frontend/wailsjs/runtime/runtime.d.ts` 和 `frontend/wailsjs/runtime/runtime.js`。这些看起来是 Wails CLI 版本差异造成的生成文件变化，不属于本次核心业务逻辑改动，建议提交前由开发同事确认是否需要保留。
+- `go.mod`、部分 `frontend/wailsjs/go/*` 文件在 `git status` 中可能因换行符显示为修改，但当前 `git diff --name-only` 未显示实际内容差异。
+- 本文档本身是新增的本地说明文件，不属于产品运行逻辑。
+- 另有一份未跟踪文档 `yuanzhipeng提交内容梳理.md`，是之前梳理 yuanzhipeng 提交内容生成的说明文档。
+
+## 五、当前实际内容差异文件
+
+根据 `git diff --name-only`，当前有实际内容差异的文件如下：
+
+```text
+build/windows/installer/project.nsi
