+# 项目协作准则
+
+本文件适用于整个 `health_project` 仓库。处理任务时按改动风险分级，验证强度与风险匹配，避免小改动套用重型流程。
+
+## 默认规则
+
+- 默认不执行 `git add`、`git commit`、`git push`、合并、回滚或创建分支；只有用户明确要求时才进行。
+- 保留工作区中用户已有的未提交改动，不覆盖、不清理、不顺带重构。
+- 数据库、上传文件、密钥、生产配置和用户数据不视为普通文件；任何写入、迁移、删除或恢复操作必须先获得用户明确确认。
+- 只修改用户指定的端和功能范围。发现相邻问题可以说明，但不要擅自扩大修改范围。
+
+## 小改动：快速处理
+
+适用于颜色、字号、间距、圆角、文案、图标、单个组件简单布局等不涉及状态、接口和数据的调整。
+
+1. 确认具体文件和修改范围。
+2. 直接完成修改。
+3. 执行格式化。
+4. 进行一次快速编译或静态检查，二者按实际需要选择。
+5. 简要说明改动结果。
+
+不运行完整测试套件，不额外编写计划文档，不提交 Git。
+
+## 中等改动：针对性验证
+
+适用于页面交互、Provider、路由、表单逻辑、接口调用、跨端数据展示、启动脚本和配置修改。
+
+1. 检查相关代码和现有改动。
+2. 修改前简要说明方案。
+3. 完成代码修改和格式化。
+4. 运行静态检查或编译。
+5. 只运行与本次改动直接相关的测试。
+6. 必要时启动对应页面或接口验证一次。
+
+默认不提交 Git。
+
+## 大改动：完整验证
+
+适用于完整新功能、多页面联动、登录、聊天、蓝牙、AI 核心流程、后端结构调整和大范围重构。
+
+1. 阅读相关代码、文档和交接资料。
+2. 与用户确认范围、交互和成功标准。
+3. 分步骤实施，并在关键阶段做针对性检查。
+4. 完成后运行 Flutter 和后端相关完整测试。
+5. 汇总改动、验证结果和遗留问题。
+
+## 高风险改动：确认后执行
+
+适用于数据库迁移或数据修复、大量删除、用户数据、上传文件、签名、生产配置、部署，以及 Git 提交、推送、合并和回滚。
+
+1. 先进行只读检查，确认精确目标和影响。
+2. 向用户说明风险、影响范围和恢复方式。
+3. 必要时先制作可验证的备份。
+4. 获得用户明确确认后再执行。
+5. 执行后进行完整验证并报告结果。
+
+用户在具体任务中的直接指令始终优先于本文件。

+# 小脉健康项目全面检查报告
+
+检查日期：2026-07-14  
+检查范围：Flutter Android 真机主要用户路径、Flutter 静态检查与测试、.NET 后端测试、前后端接口对应关系、用户/医生/管理员业务逻辑、权限安全、合规页面与 Android/iOS 发布准备。  
+本轮只检查，没有修改业务代码，也没有使用 Docker。
+
+## 一、总体结论
+
+项目主体功能已经比较完整，普通用户主路径能进入，当前 Flutter 静态检查通过，Flutter 47 项测试和后端 44 项测试全部通过。但测试通过不等于已经稳定：本次仍确认了多项自动测试没有覆盖的真实断点。
+
+当前不适合进入正式环境或商店审核。最优先的不是继续统一小间距，而是先处理问诊鉴权、管理员验证码、上传文件访问、蓝牙上传、账号注销清理和正式包权限。这些问题会影响真实数据、安全或用户是否能完成任务。
+
+## 二、必须先修的问题
+
+### 1. AI 流式聊天的 token 只被“读出来”，没有验证真伪
+
+- 用户表现：正常用户不一定马上发现，但攻击者可以自己伪造一个 token，冒充任意用户进入 AI 对话、读取该用户上下文，并可能触发健康数据写入。
+- 原因：SSE 接口没有强制登录；备用 token 处理只解析 JWT 内容，没有校验签名、过期时间、签发方和接收方。
+- 位置：`backend/src/Health.WebApi/Endpoints/ai_chat_endpoints.cs` 的 `GetUserIdFromToken`。
+- 优先级：最高。
+
+### 2. 医生问诊实时通道没有登录和问诊归属校验
+
+- 用户表现：知道问诊编号的人可以加入房间，甚至把自己声明成“用户”或“医生”发送消息；消息还会真实写入数据库。
+- 原因：SignalR Hub 没有鉴权，加入房间和发送消息时也没有核对当前账号是否属于该患者或医生。
+- 位置：`backend/src/Health.WebApi/Hubs/ConsultationHub.cs`。
+- 优先级：最高。
+
+### 3. 管理员存在固定手机号和固定验证码
+
+- 用户表现：正式环境若沿用当前代码，知道固定号码的人可用 `000000` 登录管理员端。
+- 原因：管理员手机号和验证码直接写在认证服务中，而且不只在开发环境生效。
+- 位置：`backend/src/Health.Infrastructure/Auth/AuthService.cs`。
+- 优先级：最高。
+
+### 4. 上传的报告、聊天图片和 PDF 可被未登录访问
+
+- 用户表现：文件链接一旦泄露，不登录也能打开健康报告或聊天附件。
+- 原因：整个 `/uploads` 目录作为公开静态目录提供，没有按用户、医生关系或临时授权校验。
+- 位置：`backend/src/Health.WebApi/Program.cs` 的上传目录静态映射。
+- 优先级：最高。
+
+### 5. 蓝牙血压计能读到数据，但自动上传会失败
+
+- 用户表现：设备连接成功、血压已经读取，最后却提示上传失败；血压和心率不会真正保存到后端。
+- 原因：前端提交到 `/api/health-records/batch`，当前后端没有这个接口。
+- 位置：`health_app/lib/pages/device/device_management_page.dart` 与 `backend/src/Health.WebApi/Endpoints/health_endpoints.cs`。
+- 优先级：高。
+
+### 6. 每次打开医生问诊页都会创建一条新问诊并消耗次数
+
+- 用户表现：只是进入页面看一下、没有发送任何内容，也会新增问诊；反复进出会快速消耗每月次数。显示剩余 0 次时仍可能继续创建，甚至出现负数。
+- 原因：前端初始化先查次数，然后无条件创建；后端创建接口没有真正执行三次上限，也没有验证医生仍然有效。
+- 位置：`health_app/lib/providers/consultation_provider.dart`、`backend/src/Health.WebApi/Endpoints/consultation_endpoints.cs`。
+- 优先级：高。
+
+### 7. 问诊消息发送失败时仍显示为已发送
+
+- 用户表现：网络断开或服务器失败后，消息仍留在聊天里，没有失败标记和重试入口，用户会误以为医生已经收到。
+- 原因：发送异常被静默忽略，本地消息没有回滚或转成失败状态。
+- 位置：`health_app/lib/providers/consultation_provider.dart` 的 `sendMessage`。
+- 优先级：高，且不符合“不能假成功”的项目要求。
+
+### 8. Android 正式包没有网络权限
+
+- 用户表现：Debug 真机可联网，但以后构建 release 包后，所有登录、数据、AI 和报告请求都无法联网。
+- 原因：`INTERNET` 只在 debug/profile Manifest 中，main Manifest 没有；release 不会合并 debug 配置。
+- 位置：`health_app/android/app/src/main/AndroidManifest.xml`。
+- 优先级：正式包前必须修。
+
+### 9. 账号注销只删数据库记录，不会清理服务器上传文件
+
+- 用户表现：App 显示账号已删除，但报告原图、聊天图片、PDF 等仍可能留在服务器目录；公开链接仍可能继续访问。
+- 原因：账号注销批量删除数据库数据时没有收集并删除物理文件。单独删除报告有删文件，注销账号没有走同一流程。
+- 位置：`backend/src/Health.Infrastructure/Users/EfUserRepository.cs`。
+- 优先级：高，涉及合规承诺和真实删除。
+
+### 10. iOS 相机和相册权限说明缺失
+
+- 用户表现：以后在 iPhone 上拍饮食、拍报告或选相册时，系统可能直接终止 App，而不是正常弹出权限框。
+- 原因：Info.plist 有蓝牙说明，但没有 `NSCameraUsageDescription` 和 `NSPhotoLibraryUsageDescription`。
+- 位置：`health_app/ios/Runner/Info.plist`。
+- 优先级：iOS 调试前必须修。
+
+## 三、重要功能和稳定性问题
+
+### 11. 多个请求同时遇到登录过期时，可能刚刷新成功又被强制退出
+
+多个 401 会同时拿同一个刷新 token。第一个请求刷新并保存新 token 后，第二个请求可能因旧 token 已失效而失败，随后把刚保存的新 token 一并清掉。用户会偶发跳回登录页。
+
+位置：`health_app/lib/core/api_client.dart` 的 401 刷新逻辑。
+
+### 12. 启动时只要服务器暂时连不上，就把用户当成未登录
+
+刷新 token 的请求遇到断网或本地后端未启动时，认证状态直接变为未登录，但本地 token 又没有清除。用户会看到登录页，网络恢复后也不会自动重试，只能重启或重新操作。
+
+位置：`health_app/lib/providers/auth_provider.dart` 的 `_checkAuth`。
+
+### 13. 问诊轮询用随机 GUID 判断“之后的消息”，可能漏消息
+
+SignalR 失败后会回退轮询。后端把随机消息 ID 与上一条随机 ID 做大小比较，这不等于消息时间顺序，可能漏掉医生新回复。正确游标应基于服务器时间或稳定递增字段。
+
+位置：`backend/src/Health.WebApi/Endpoints/consultation_endpoints.cs`。
+
+### 14. 问诊 AI 开场白只存在前端，没有保存
+
+用户看到的“AI 分身问候”不是数据库消息，医生端看不到；重新进入又会新建问诊并生成另一条本地问候，历史不连续。
+
+位置：`health_app/lib/providers/consultation_provider.dart`。
+
+### 15. 短信验证码没有频率、次数和防刷限制
+
+发送接口可反复调用，验证码校验也没有失败次数限制。正式短信接入后会产生短信轰炸、费用和验证码暴力尝试风险。
+
+位置：认证端点和 `AuthService`。
+
+### 16. 管理员新增、停用、修改、删除医生时，几套医生数据可能不同步
+
+- 手机号已属于普通用户时，仍可创建医生实体，但不会把已有用户升级并绑定医生档案。
+- 修改医生手机号/姓名时，没有同步医生登录账号与医生档案。
+- 停用医生只改一处状态，医生档案的状态可能仍是启用。
+- 删除医生后，医生登录用户仍可能保留 Doctor 角色，但档案已失去关联，登录后只能看到“档案未关联”。
+- 医生手机号没有唯一约束，可能出现重复医生。
+
+位置：`backend/src/Health.Infrastructure/Admin/AdminService.cs`。
+
+### 17. 附件本地路径没有限制在 uploads 目录内
+
+附件 URL 中的相对路径直接拼到服务器路径，没有做规范化后再确认最终路径仍位于 uploads 内，也没有核对文件是否属于当前用户。这会带来跨用户读取或路径越界风险。
+
+位置：`backend/src/Health.Infrastructure/AI/AttachmentContextBuilder.cs`。
+
+### 18. 通知点击先联网标记已读，失败时目的页面也打不开
+
+用户点一条未读通知时，先请求后端标记已读；如果这一步失败，后续报告/用药/健康页面不会打开，也没有明确提示。
+
+位置：`health_app/lib/pages/notifications/notification_center_page.dart`。
+
+### 19. 用户端与医生端部分“今天/本月”按 UTC 计算
+
+中国时区的凌晨时段可能被算到上一天或上个月，影响问诊次数、今日随访和提醒归类。正式环境应统一明确业务时区。
+
+位置：问诊和医生工作台中使用 `DateTime.UtcNow.Date` 或 UTC 月份的逻辑。
+
+## 四、UI 与交互问题
+
+### 20. 用药和运动列表默认露出整片红色删除背景
+
+真机截图中，用药行和运动行在没有滑动时已经整行变红；运动行还出现“打卡”和“删除”重叠。用户会误以为数据异常或正处于危险删除状态。
+
+原因是通用滑动删除组件始终铺红色底层，而这些列表行本身透明。测试只验证滑动动作，没有验证未滑动时的最终视觉。
+
+证据：`05-medications.png`、`09-exercise.png`。  
+位置：`health_app/lib/widgets/common_widgets.dart`。
+
+### 21. 首页多个纯图标按钮缺少无障碍名称
+
+真机可访问性结构中，菜单、附件、输入框和发送按钮等多个可点击区域没有名称。普通用户能凭图标猜，读屏用户无法知道用途。
+
+证据：`01-current.xml`。
+
+### 22. 删除动作风格不统一
+
+报告、用药、运动使用滑动删除，通知使用整行侧滑，蓝牙设备直接显示红色垃圾桶，设置页则用大按钮。交互成本和误触风险不同。建议统一为“列表行滑动后显示删除 + 二次确认用于高价值数据”。
+
+### 23. 设置页的红色占比过重
+
+“删除账号”和“退出登录”两个大面积危险操作占据页面最强视觉层级，反而压过消息、隐私和服务协议。删除账号保持红色是合理的，但退出登录不必使用整块高饱和红色。
+
+证据：`12-settings.png`。
+
+### 24. 侧边栏健康仪表盘过于抢眼
+
+大面积蓝紫粉渐变和四个小框成为最强区域，与项目“克制、专业、模块色只做识别”的偏好有偏差；指标小字和透明边框的对比度也偏弱。
+
+证据：`02-drawer.png`。
+
+### 25. 空状态表达不统一
+
+复查随访使用居中图标和说明；饮食使用一条白色容器；其他页面可能只留空白。建议统一空状态的标题、原因和下一步操作，但不需要每页再套一张大卡片。
+
+证据：`06-diet-records.png`、`08-followups.png`。
+
+### 26. 部分图标按钮只有约 40dp
+
+例如蓝牙页顶部新增按钮使用固定 40×40，低于常见的 48dp 触控建议；对手部不便或视力较弱的健康类用户不够友好。
+
+### 27. 大字体、横屏、小屏和读屏尚无验证证据
+
+许多页面使用固定高度、固定行布局和多个并排信息块。当前只在一台 1440×3200 Android 真机、默认字体比例下检查，不能据此确认大字体和 iOS 横屏不会溢出。
+
+## 五、合规与发布准备问题
+
+### 28. 合规文档仍有主体和联系方式占位符
+
+隐私政策、服务协议、个人信息清单和 SDK 清单里仍有 `xxx`、待定短信服务商等内容，不能用于正式审核。
+
+### 29. App 内文档与 H5 文档存在多套日期和内容
+
+App 内隐私/协议日期为 6 月 29 日，个人信息与 SDK 清单为 7 月 9 日；H5 清单日期为 7 月 7 日。以后修改一处很容易漏另一处。建议确定单一内容源或至少增加一致性测试。
+
+### 30. “关于我们”写了并不存在的意见反馈入口
+
+文档提示“设置 → 意见反馈”，实际设置页没有该入口；版本还写成 `Build 20260101`，与当前 `1.0.0+1` 不一致。
+
+### 31. 用户同意协议没有服务端记录
+
+当前“同意”只是登录页内存中的一个布尔值，未保存同意时间、协议版本或政策更新后的重新同意记录。服务端接口也不要求同意状态，无法证明用户同意了哪一版条款。
+
+### 32. Android 权限声明偏多且缺少版本限制
+
+当前声明了蓝牙广播权限，但 App 主要是扫描/连接；旧版存储和蓝牙权限也没有按 Android 版本加 `maxSdkVersion`。正式个人信息清单应与实际最小权限保持一致。
+
+### 33. 本地 token 使用普通 SQLite 明文保存
+
+符合项目“不用 shared_preferences”的约定，但 access token 和 refresh token 没有系统级加密保护；同时 Android 也未显式关闭备份。正式版本需要决定是否改用系统安全存储或加密数据库，并限制备份。
+
+### 34. iOS 名称和方向仍是模板状态
+
+Info.plist 的显示名称还是 `Health App`，并允许 iPhone 横屏；当前页面主要按竖屏设计，尚未验证横屏。Bundle ID、签名和证书则仍按项目计划待配置。
+
+### 35. CORS 当前允许任意来源并携带凭据
+
+本地调试方便，但正式环境应只允许确定的 H5/管理端域名，不能继续接受任意 Origin。
+
+## 六、已确认正常或已有保护的部分
+
+- 当前 Flutter `analyze` 无错误。
+- Flutter 47 项测试全部通过。
+- 后端 44 项测试全部通过。
+- 报告、用药、饮食、运动、健康数据等主要删除接口都按当前用户筛选，不是只删前端显示。
+- 单独删除报告时会同时删除报告原文件。
+- AI 历史对话恢复后仍保留原 conversationId，可以继续发送新消息；历史确认卡只读是合理保护。
+- 管理员和医生普通 HTTP 端点已有角色过滤，问题主要集中在固定管理员验证码、医生数据同步和未鉴权 SignalR Hub。
+- 设置、通知、报告列表已经较接近“一行一行、文字区分隔线”的目标风格。
+- 隐私政策、服务协议、个人信息清单、SDK 清单和关于我们均已有 App 内入口与 H5 文件。
+
+## 七、真机流程健康度
+
+1. 首页与 AI 对话：可进入；视觉基本完整，但纯图标无障碍名称不足，AI SSE 鉴权有严重后端风险。
+2. 侧边栏：可打开；功能入口齐全，仪表盘色彩和层级偏重。
+3. 健康档案：可加载和编辑；固定保存区需要继续验证大字体遮挡。
+4. 报告管理：列表正常；文件公开访问是严重隐私风险。
+5. 用药管理：数据能加载；列表红底显示错误明显。
+6. 饮食记录：日期、空状态和趋势能显示；空状态样式与其他页不统一。
+7. 健康日历：日期和计划能显示；业务时区需要后端统一。
+8. 复查随访：空状态清楚；本次账号没有数据，未实测详情。
+9. 运动计划：数据能加载；红底和操作文字重叠明显。
+10. 蓝牙设备：绑定设备能显示；自动读取后的批量上传链路断开。
+11. 通知中心：历史和未读数能显示；未读通知在网络失败时可能打不开目的页。
+12. 设置与合规入口：入口齐全；危险操作权重过高，文档仍有占位和不一致。
+13. 个人信息：真机运行版本可进入；检查期间源代码刚加入新的基本资料编辑入口，当前运行包尚未热更新到这一版。
+14. 医生端：已完成代码与接口核对；没有医生测试账号，本次未做完整真机流程。
+15. 管理员端：已完成代码与接口核对；没有实际执行新增/停用/删除，避免改变真实数据。
+16. iOS：仅做配置与代码检查；没有证书、Mac 构建和 iPhone 实测，不能确认界面与权限流程。
+
+## 八、证据限制
+
+- 真机截图来自本次检查时设备上正在运行的调试包。检查过程中项目源代码仍在被更新，后加入的个人资料编辑和设备错误文案没有重新构建到该运行包，因此相关结论以当前代码为准、旧界面截图只用于对应未变化页面。
+- 没有执行真实删除、账号注销、医生管理、短信发送或蓝牙测量，避免改变现有数据；这些部分通过前后端代码和接口对应关系确认。
+- 没有正式域名、HTTPS、短信服务商、对象存储、iOS 签名和商店账号，因此只检查了当前准备缺口。

+- 个人健康数据、计划、完成状态和报告状态必须以当前业务工具返回为准，不能根据聊天历史或患者背景猜测。
+- 工具没有返回的数据不得编造；暂时没有对应能力时应如实说明。
+- 一条消息可能包含多个意图，必须分别处理，不能为了简化而遗漏其中一项。
