 ## [Unreleased]
 
+### 变更
+
+- 对话与工作区共用一份列表：侧栏「对话」进入工作区「对话」标签；点开一条才进入聊天画布。工作区侧栏默认打开「项目」标签。
+- 用户可见用词对齐：员工 = 已入编部门；同事 = 同一组织里一起聊的人；专家 / 智能助手 = 尚未入编的帮手。个性化「子智能体」改为「专项助手」。群聊选择「同事或智能助手」。
+- 桌面未注册的 local guest 也能打开「模型」和「知识库」（第一台电脑免登录）。
+- 组织页导入/推送后显示落地回执，循环时间线用「是/否」而不是 true/false。
+
 ### 新增
 
 - 模型页本机大模型：Ollama 已安装但未运行时显示「启动 Ollama」（Windows 走已知安装路径的 `Ollama.exe` / `ollama app` / `ollama serve`）；缺少可自动处理的依赖时提供「一键下载安装」，否则说明需手动安装；「搜索本机模型」后台扫描 `.gguf` / `.ggml`（以及明确的本地 LLM safetensors 目录），结果进入本机列表并可注册到 Ollama 供对话切换。
