 ### 开源、构建与发布
 
 - Desktop `0.15.3` 修复本地直连手动压缩和请求有效期间的工具授权，区分取消与失败并去除重复提示，优化侧栏搜索、注册成功后的快捷键提示及笔记操作布局，减少启动和存储中的重复处理，并精简重复依赖及开发文件。不宣称整体渲染性能已显著提升；Office 实时编辑仍为设计。证据见[0.15.3 发布准备](./docs/development/release-preparation-0.15.3.md)。

+- Desktop `0.16.0` 将专家和团队角色选择移入输入框，并按会话保存选择。历史消息保留请求当时使用的角色，即使角色之后被重命名或删除也不会丢失这项上下文；schema 保持不变。
 - Desktop `0.15.14` 恢复因来源变化或移除而失败的历史监督回顾的继续操作。持续变化的来源只会在有限次数内重新冻结处理，之后自动省略，使回顾能够结束并保留其余来源的进度；设置分类增加对应图标，方便快速查找；schema 仍为 62。
 - Desktop `0.15.13` / Agent `0.15.6` 将桌面业务 SQLite 的唯一 owner 移到一个类型化 storage utility process，Assistant、Knowledge、附件、运行绑定和账本保留原路径及事务语义。直连模型在工具失败后可继续，分页输出、Magic Notes 标签、监督来源别名、设置直达预加载和文件元数据同步修正；schema 仍为 62。storage/监督 focused 编排已通过，但 C01–C07 并发验收矩阵、跨平台 storage 进程安装和低端机对照仍是明确后续门槛，不作通用性能承诺。见[发布准备](./docs/development/release-preparation-0.15.13.md)。
 - Desktop `0.15.12` / Agent `0.15.5` 增加 Telegram 私聊配置（真实 Bot 与模型完整验收仍待完成）和本地日期自定义回顾。监督图谱/来源按需读取、索引 Worker 查询、摘要缓存和选择列表窗口化减少重复工作，最终发布仍可阻塞 Main；未发布回顾省略已删除会话并重算受影响批次，历史结果保留。临时模型失败最多多试一次，可能增加费用；远程启动取消、通道交付、长消息展开状态及历史缺失时长得到修正。schema 62 增加通道支持和查询索引，升级前备份完整数据目录，降级需恢复备份。两个独立开发审计阶段共记录 15 次外部文本请求，本次发布准备没有新增；精确源码 CI 与原生打包仍为门槛。见[发布准备](./docs/development/release-preparation-0.15.12.md)。

+# Desktop 0.16.0 发布准备
+
+日期：2026-10-09。基线 `v0.15.14`，候选源码为本次发布准备提交。
+本候选只更新 Desktop；Agent 保持 `0.15.6`，不创建新的 Agent 标签。标准六平台 Desktop，
+不含 LoongArch。
+
+## 范围与兼容性
+
+- 专家和团队角色选择移动到 Composer 输入框顶部，发送前更容易发现。
+- 角色选择按会话保存，切换会话不会带入其他会话的选择。
+- 历史消息保留请求发送时使用的角色，即使角色后来重命名或删除，历史上下文仍可识别。
+- 不新增数据库 schema，Agent、runtime/acp、wire 和运行时锁版本不变。
+
+## 验证边界
+
+本候选包含 Composer、会话选择状态、历史消息元数据和角色选择的回归测试。
+完整跨平台安装、远程 Host 和未覆盖的整包验收仍以 CI 与发布工作流结果为准。
+
+## 发布门槛
+
+完成发布说明校验、测试、三套 typecheck 和 lint 后，推送候选到 `origin` 与 `github`，
+要求精确候选的主分支 CI 和生产构建通过，再由用户确认后创建不可变的 `v0.16.0` 标签。
+本轮不构建或发布 LoongArch，也不创建新的 Agent 标签。
