 ### 2026-07
 
+- **07-07 / 0.48.0**:语音输入手势升级(纯前端,后端零改动)——业界对齐调研后两端分治:① **触屏按住说话**(微信/DeepSeek 式):`pointerdown`(pointerType≠mouse)按住录音、松开转写、上滑 60px 进入"松开取消"(面板变红),pointer capture 保证滑出按钮仍收事件,touch 后合成 click 用时间窗压掉;② **桌面点击开停 + Enter/Esc 收尾**:说完按 Enter 结束转写、Esc 取消(capture 拦截防落回 textarea 触发发送)。**明确不做桌面 VAD 静音自动停**:口述需求"边想边说"停顿 3~5s 是常态,自动截断比多按一下更伤,业界听写类(ChatGPT/Google Docs/Win+H)也全是手动收尾,自动停只属于 Siri 式短指令场景。③ 录音期 `#voice-rec-panel` 替换 textarea:实时波浪(采集 chunk 顺手算 RMS,1/8 抽样,零额外开销)+ 计时 + 手势提示;iOS Safari 手势内 `ctx.resume()`;授权弹窗期间松手 → 启动完成立即收尾。
 - **07-07 / 0.47.0**:web 端语音输入(讯飞语音听写 IAT)——聊天输入区新增「🎙 语音」按钮:点击录音(Web Audio ScriptProcessor 采 PCM → 前端线性插值降采样 16k/16bit/mono)→ 再点停止 → `POST /v1/asr/transcribe`(裸 PCM body,require_user)→ 后端 `core/asr_xfyun.py` 连讯飞 wss(HMAC-SHA256 签名,9600B/帧 40ms 节奏,vad_eos=10000 防句间停顿截尾,未开 dwa 整段拼接)→ 文本 insertText 插输入框光标处(接原生 undo 栈,**不自动发送**)。60s 上限自动停(讯飞单会话限制);录音需 HTTPS/localhost;渠道只读镜像 task 按钮锁定;`XFYUN_APPID/API_KEY/API_SECRET` env 未配返 501(**当前 .env 为测试 key,待换正式**)。诊断 `scripts/diag_asr.py`(静音冒烟 / 带 PCM 文件真测);requirements 显式加 `websockets`。已实测:TTS 合成中文 5.2s 音频经端点转写逐字正确。企微语音消息(AMR 需 ffmpeg 转码)留待二期;将来流式逐字上屏可复用 `build_auth_url` 签临时 URL。
 - **07-07 / 0.46.2**:消息分页窗口对齐轮次边界(纯前端,`chat.js`)——原按固定 30 条翻页/跳转,窗口边界常切在 assistant 工具调用序列中间(顶部出现孤儿 tool 消息),点目录圆点用 `before_idx=idx+11` 启发式(长轮拉不全、短轮混无关上文)。业界调研确认:分页单位保持消息条数是共识(Discord/OpenAI 均按条 + 每页上限,轮次大小无上界不能当传输单位),轮次归组属渲染层职责。实现:idx 连续 + outline 已含全部 user 轮次起点 → 前端可精确算区间,后端 API 零改动。① 向上翻页 `alignedEarlierLimit`:从窗口顶往前按整轮累加攒够 30 条,新窗口顶恒为 user 消息;② 圆点跳转:`after_idx=起点-1` + 相邻边界差精确拉整轮(短轮补到 30 铺满、超大轮按 `MSG_FETCH_MAX=100` 截断,后续向上加载逐步自愈对齐);③ outline 未加载/idx 不在 outline → 回退旧按条行为。后端 limit 无 clamp,前端以 100 硬上限自律。
 - **07-07 / 0.46.1**:撤除企微欢迎推送机制——实际部署采用聊天优先布局(不配应用主页 + 菜单「工作台」按钮)后,点应用直进会话,冷启动问题不复存在,0.46.0 的欢迎推送成了死重:删 `wecom_welcomes` 表(migration 0021 撤下,DB 已 downgrade 回 0020,表建后无一行写入)、`maybe_send_wecom_welcome`、免登回调欢迎钩子、群发脚本、`list_visible_userids`。**保留**:未绑定入站回绑定指引(聊天优先下必需)、`core/branding.py` 品牌单一源。RUN.md 企微段只留推荐布局 + 未绑定指引两条。
