 - 管理端业务路由集中在 `frontend/src/router/index.ts`，覆盖首页、AI 面试、训练运营、问题榜、案例、知识空间、SOP、资料处理、大喇叭、五渠道直通反馈、系统配置、组织权限和成长激励；侧栏过滤在 `frontend/src/layout/components/Sidebar/index.vue`，不要恢复若依默认全量菜单。
 - 用户侧只改 `mobile-uni/src/pages/*`；员工、候选人、主管首页分别为 `/pages/user/today/index`、`/pages/candidate/index/index`、`/pages/supervisor/index/index`，旧 `/h5/user|candidate|supervisor|employee|admin` 只做兼容重定向，底栏固定「今日/练/问/我」。“问”统一调用 `/api/aihr/agent/messages|messages/media`，服务端规划意图并按固定策略选择既有工具，客户端不得提交 `toolCode`；旧知识查询仅作底层/兼容。登录端短期会话为 30 分钟/最新 6 轮，原文件/视频经 `/api/knowledge/resources/{attachmentId}/content` 重新鉴权。总结卡只接受当前答案中的最多 5 个 `DOCUMENT` 引用 `fragmentIds`，服务端重新鉴权后仅基于这些片段生成固定「问题/建议/标准」结构；不得二次检索，失败不得拿原文冒充结构化步骤。全网外发必须先同意，显式记忆先出确认卡，再通过不透明 `draftId` 按 `PRIVATE/COMPANY` 确认；`COMPANY` 仅为 `PENDING`，不得冒充已派单或送达。`aihr_agent_run` 不保存问题、答案或附件，外部知识 API 保持无状态。
-- 大喇叭详情追问只让客户端传 `broadcastMessageId`，消息正文、附件文本、租户和身份均由服务端重新校验并加载；撤回、跨租户或非在职员工不得继续使用消息上下文。单条消息最多绑定一个属于当前租户、当前上传人且状态为 `READY` 的公司文件；员工端只返回摘要、受控下载入口和有原文短引用佐证的多岗位解读，不返回提取全文或原始 OSS 地址。默认岗位视角由服务端按认证员工岗位选择，客户端不得提交视角代码；解读处于 `PENDING/PARTIAL/FAILED` 不阻断摘要、原文件、发布或追问。消息/知识回答不得把通用建议包装成当前员工的真实待办，强行动入口只能来自服务端已授权的真实任务数据。
+- 大喇叭发布支持 `ALL/TARGET_ONLY`：`TARGET_ONLY` 必须有目标并冻结收件人，列表、详情、未读、阅读、附件和追问统一复核可见性，非目标按不存在处理；`ALL` 下目标只作定向提醒。详情追问只让客户端传 `broadcastMessageId`，消息正文、附件文本、租户和身份均由服务端重新校验并加载；撤回、跨租户或非在职员工不得继续使用消息上下文。单条消息最多绑定一个属于当前租户、当前上传人且状态为 `READY` 的公司文件；`allowDownload=false` 时客户端不展示且服务端拒绝下载，在线查看返回受控文本并记录审计，动态水印只用于追溯。主题标签必须带原文短依据且不得参与授权。员工端不返回提取全文或原始 OSS 地址；默认岗位视角由服务端按认证员工岗位选择，客户端不得提交视角代码；解读处于 `PENDING/PARTIAL/FAILED` 不阻断摘要、受控查看、发布或追问。消息/知识回答不得把通用建议包装成当前员工的真实待办，强行动入口只能来自服务端已授权的真实任务数据。
 - 直通车固定为总裁、财务、人力、审计、运营五个渠道；业务匿名只隐藏处理端的提交人展示，服务端仍保留内部提交账号供本人查询、幂等和审计。`direct_president/direct_finance/direct_hr/direct_audit/direct_operations` 只处理各自渠道，`superadmin` 可处理全部；只有 `superadmin` 可维护获批处理人，候选人必须由服务端限定为当前租户已启用的非 APP、非超级管理员后台用户，写入须校验租户上下文，系统不得自动把任意账号绑定成真实收件人。当前产品边界只允许一次正式回复，不扩展为多轮聊天、工单、转派或 SLA。员工提交页支持语音转文字输入（复用 `/api/ai/asr` 与 `services/speech.ts`）；该表单页以文字为主，录音不可用或权限失败时只提示改文字，是不提供音频文件降级的明确例外。
 - 术语和数据边界：工作助手承载日常事实与确认式记忆；现有 `/pages/user/report/index`、`/api/aihr/work-report/**` 和 `aihr_work_report` 只承载 CASE/VIDEO/SOP/KNOWLEDGE 四类投稿审核，产品名为“成果投稿”；“今日工作成果”按员工 + 项目 + 自然日从已确认记录确定性聚合，员工页为 `/pages/user/work-results/index`，主管页为 `/pages/supervisor/work-results/index`，默认当日但允许查看历史日期且不得选择未来日期。不要把三条链路合表或自动互写。多项目交互只让用户按项目名称选择，内部项目编码必须由服务端按当前身份复核，不让用户输入编码。
 - 不要把三端概括成全模态：员工对练/每日题、问师傅和直通车反馈支持文字/语音，问师傅图片/视频只用于本次分析，案例传音频；候选面试支持文字/语音，资料可传文档/图片但图片不参与评分；主管写文字复盘/指派并回听录音。员工对练图像/视频情境、服务录像回放和方言正式验收仍未完成；语音继续复用 `services/speech.ts` 与 `/api/ai/asr`。
 - 问题榜奖励只记积分/学习学分，不得擅自增加现金、提现、预算或税务语义；选最佳答案和考试提交必须保持请求幂等。
+- 问师傅的未解决答案只有在本人先提交 `down` 反馈并再次确认后，才能由服务端重读本人查询审计和反馈创建 `PENDING` 问题榜条目；客户端不得提交改写答案、引用、身份或奖励，重复请求必须返回同一问题。正式学习任务与每日三题分开：材料只允许当前租户 `READY` 附件，任务保存材料版本、周期、起止时间和完成规则；`EXAM_PASS` 只能由关联考试通过完成，随机组卷只从已审核启用题库抽取并在发布时冻结来源和答案。
+- 案例与训练高分只进入经验候选；业务审核不等于正式发布。正式经验必须另行确认来源授权、脱敏、适用岗位、负责人、版本和生效期后进入 `PUBLISHED`，员工只可召回当前生效的正式经验；下线后立即停止员工召回。案例、成果投稿和知识空间不得自动互写。
 - 全网 AI 与企业问师傅必须分入口、分来源和分免责声明；提供方仅允许公网 HTTPS，修改地址/密钥后必须连接测试成功才能启用，未配置时明确不可用且不生成假答案。
 - 多租户知识平台的有效范围是“租户 + 调用应用绑定 + 主体授权”的交集；不信任客户端传入身份，API_TOKEN 不得进入浏览器或小程序包。生产排序规则以 `aihr_knowledge_info.tenant_id` 为基准，新表最后执行 `aihr_20260718_release_collation_compat_mysql8.sql`。
 - 移动端首页接口：`GET /api/aihr/mobile/home/{role}`，当前 `@SaIgnore` 公开只读 seed，用于 H5 首屏 API 优先 + 本地 fallback；后续确定小程序登录后再接移动端 token，不复用管理后台登录态。

 ## Unreleased
 
+- **2026-08-02，功能复核清单首批增量已实现并完成本地验证，未部署**：当前工作树新增大喇叭 `ALL/TARGET_ONLY` 可见性、受控在线查看与动态水印、下载门禁和带原文依据的主题标签；问师傅未解决反馈确认转待审核问题；正式学习任务、审核题库随机组卷及考试关联；案例经验“候选→审核→发布→下线”；原生异常恢复回归和资料暂存盘容量健康门禁。管理端生产构建、移动端类型检查与 `216/216` 单测、后端 `838/838` 测试及迁移静态清单通过；`390×844` 已验证员工主要入口和登录门禁。Docker/MySQL 未运行，四个 `aihr_20260802_*` 迁移尚未执行，管理端认证业务、峰值压测、签名 APK、真机、生产发布和严格试点均未验收。
 - **2026-07-31，8 月 1 日受控内部公测门禁收口为 Go**：最新后端 JAR SHA-256 `d5145194024ba3526a869e3270df6d71468931b96ba9aebb93121592e54012eb` 已上线，正式政策模式只允许当前有效、已批准、版本与原文件哈希完整且与问题领域相关的来源进入回答；没有相关制度时失败关闭，不再回退经验萃取或访谈材料。使用生产现有 APP 账号重跑 30 道策略题，11 题只引用已批准正式来源，分期缴费题返回 `NO_EVIDENCE`，其余冲突、无依据和越权题按边界返回，合计 `30/30`；证据不保存手机号、验证码、令牌、问题或答案正文。生产 5 个 `v1.1` 场景及独立审核链、五通道各 2 名有效处理人、本通道正例/跨通道拒绝/一次正式回复 `5/5`、五类负责人委托签认，以及 `0.1.17 (117)` 的 DCloud 测试签名受控分发例外均已回填。严格内容门禁和生产只读就绪门禁均通过；同时修复就绪脚本把含 `|` 的场景快照直接作为 SSH 参数导致远端误解析为管道的问题，改为 Base64 单参数传输。该 Go 仅适用于受控内部公测，不代表应用商店发布、企业正式签名或阶段一严格试点窗口通过。
 - **2026-07-30，5 个真实访谈场景已落入生产停用草稿，正式内容门禁保持 No-Go**：从 `D:\20260730` 的 12 份访谈材料中选择 7 份代表性来源，以脱敏主题和 SHA-256 登记到 `aug1-life-advisor-candidate-v0.2`，形成管道漏水责任、物业费争议、维修延期、停车冲突、收费与整改并行五个真实业务场景。已登录生产管理端逐条保存并按编码回查，场景总数从 `100` 增至 `105`，当前启用数保持 `86`，五项均为 `草稿 / 草稿未提交 / 停用`；费用复核作为业务动作和审核职责保留，不把系统不支持的财务部门伪装成住宅训练岗位。候选文件仍为 `publishable=false`，30 道政策题仍无标准答案；严格门禁继续准确保持正式场景 `0/5`、问题证据 `0/30`，本项没有提交业务审核、启用或发布场景，也没有部署代码、重启服务或执行 schema 迁移。
 - **2026-07-30，`0.1.17 (117)` Android 技术候选与五通道处理人配置完成收口，正式发布仍为 No-Go**：管理端“直通反馈”五通道处理人配置已在线可用，生产按有效后台用户规则只读复核后，`direct_president`、`direct_finance`、`direct_hr`、`direct_audit`、`direct_operations` 均为 `2/2`；Android 权限 Activity 生命周期修复已进入新的 DCloud 测试签名 APK `mobile-uni/dist/debug/bangdao-0.1.17-dcloud-test.apk`，包体 SHA-256 为 `0A8581D70A5988E4BDCF4BB3F0C88B4608FA8C6785FDCF1569DD56CE88E27F60`，包名 `com.yincheng.wygj`、版本 `0.1.17 (117)`、target SDK 35、禁止明文流量和签名深检均通过。vivo V2443A（Android 15/API 35）已在同一签名包上完成覆盖安装、正式账号登录、员工首页、学习中心、麦克风允许/拒绝/最终恢复、系统音频选择器、App 媒体选择器、生产 ASR、成果投稿确认和五通道入口回归；测试成果形成 `#7 / PENDING` 待审核记录，测试音频与会话已清理，最终无 Crash/ANR。移动端 209 项、后端定向 46 项、管理端定向 4 项、类型检查、App-Plus 构建、发布资源门禁和生产认证态冒烟均通过；认证态 UI 审计改为只从调用参数或环境变量接收手机号/验证码，报告、控制台和默认截图路由不再持久化认证凭据。该 APK 仅安装到已连接真机，未进行受控分发，也未在本项重发 H5、管理端、后端或 schema。严格门禁仍为正式场景 `0/5`、题库证据 `0/30`、通道验收 `0/5`、负责人签认 `0/5`、受控分发 `PENDING`，且同包离线、WebRTC、图片/视频/文档上传、受控下载和主管/候选人角色尚未验收，因此只能作为继续受控验收的技术候选，不能签署 8 月 1 日正式 Go。

+- 问题榜与学习：本人 `down` 反馈可经再次确认创建待审核问题；学习任务保存材料版本、周期和考试完成规则，随机组卷只使用审核启用题库并冻结题目来源。正式题库内容和任务规则仍须业务审核。
+- 经验治理：案例审核与正式发布拆分，只有来源授权、已脱敏、适用岗位、版本、负责人和生效期完整的 `PUBLISHED` 经验才向员工开放；下线立即停止召回。
+- 运行门禁：资料暂存盘默认要求至少 10GiB 可用空间，生产 HTTP 请求启用 P50/P95/P99 指标；约 600 名用户不是 600 并发，压测模型和通过阈值仍待业务、实施和运维签认。

 历史图片/视频在视觉模型不接受原始分辨率/编码，或模型、ASR、关键帧链路没有返回可检索文字时，旧逻辑会留下状态 0、片段 0 的附件，页面长期显示“等待解析”，却没有从原件重新入队的入口。当前实现先对图片纠正方向、缩放和重编码；异步队列只有生成至少一个片段才进入完成态，零片段明确保持可重试失败。管理端可调用 `POST /api/knowledge/doc/processing-tasks/{attachmentId}/retry`，服务端按当前租户从原 OSS 对象重新暂存，通过附件状态 CAS 防止重复入队，并用 `source_attach_id` 关联新队列条目。

 - 服务端目录导入接口为 `POST /api/knowledge/doc/import-local-task`，只读取导入根目录下的相对目录，后台逐文件复用同一上传解析链路；`POST /api/knowledge/doc/import-tasks/{id}/cancel` 可取消运行中任务；`POST /api/knowledge/doc/import-local` 保留为同步调试接口。这组接口仅供运维/调试，不在资料处理页提供入口。
 - 启用 `aihr_model_config.category='vector'` 的模型配置后，上传会同步写入片段 embedding，并尽力 upsert 到 Qdrant；模型配置页可查看 Qdrant 维度、点数和片段向量数，并在维度不一致时重建索引；未配置或 Qdrant 不可用时只走 MySQL Fulltext/seed fallback，不影响检索。
