+- 已确认工作区干净，生产代码保持 `47917094` 的 A 组：向上滚动仍按 80 条揭示，DOM 窗口化仍保留。
+- 当前聊天窗口和时间线定向测试：59/59 通过，包含 2,000 条消息连续滚动、实际挂载数量上限、锚点稳定、状态恢复和 80 条历史揭示。
+- App 单元测试：342/350 通过；8 个失败均为等待状态圆点的既有异步断言，失败位置不涉及历史窗口逻辑。
+- `npm run build:bundle`：通过。
+- 当前 A 组首次可重复的 `npm run perf:app`：通过。长会话打开交互延迟 54.4 ms；长会话滚动无长任务，帧间隔 p95 8.5 ms；流式输入延迟 p95 10.0 ms；流式输入场景无长任务。
+- 性能基准内存回收：24 次切换后 mounted panes 保持 6，DOM 从 24,746 降至约 2,446，堆从 50.5 MB 回收至约 22 MB，后半段增长约 0.1 MB。
+- 之前记录的“A 组 composer 初始化超时”未在当前回退后的基线复现；现在已经取得有效 A 组数据，后续可在同一 bundle 和环境下重新接线 B 组做严格交替 A/B。
+- minimap 尚未实现；在 B 组完成交替测量前不进入 minimap 性能对比。
+- B 组已重新接线：`ConversationHistorySlot` 对完整会话传入 `conversation.messages.length`，App 层不再维护 80 条可见数量状态；摘要会话仍走原有历史加载流程。
+- B 组 App 历史回归：4/4 通过，覆盖无历史闸门、长会话有界提交、暖切换位置和展开状态、超过 500 条历史保留。
+- B 组 `npm run build:bundle`：通过；改动文件 web 类型检查和 lint：通过。
+- B 组 `npm run perf:app`：通过。长会话打开交互延迟 46.8 ms，长会话滚动无长任务、帧间隔 p95 8.5 ms；流式输入延迟 p95 9.5 ms，无长任务。
+- A/B 基准对比：B 组 DOM 在长会话滚动后约 2,644、24 次切换回收后约 2,446；A 组对应约 2,632 和 2,446。B 组 24 次切换后的堆约 22.9 MB，后半段增长约 0.1 MB；A 组约 22.0 MB，后半段增长约 0.1 MB。当前没有观察到明显滚动、流式或内存回收回归。
+- 全量 App 测试：B 组 341/350 通过；剩余 9 个中 1 个为已迁移历史测试前的旧断言结果，8 个仍为既有等待状态圆点异步断言。迁移后的历史相关测试已单独通过。
+- B 组尚未提交；下一步继续做多轮交替 A/B 和低端机模拟，再决定是否进入 minimap。

+### 2026-10-12 交互修订
+
+评审发现初版 minimap 是悬浮在中部的 220 px 小条，视口指示经 `requestAnimationFrame` + React 状态更新而滞后于滚动，且没有悬停放大。已修订：
+
+- minimap 替代消息滚动区的原生滚动条：`.chat-history-pane > .chat` 隐藏原生滚动条，minimap 高度与滚动区 `clientHeight` 一致并贴合右侧。
+- 视口滑块在 `scroll` 事件和 `ResizeObserver` 回调中同步写入 `transform`，不经过 React 提交或下一帧；滚动区尺寸不变时只写 `transform`，不读布局。
+- canvas 仅在消息变化、行高测量变化、尺寸变化或展开／收起时重绘；普通滚动不重绘。
+- 悬停时展开为 96 px（窄屏 64 px）的缩略长图：用户消息靠右、助手消息靠左并按内容长度给出线宽；拖动中离开不收起。
+- 点击轨道将滑块中心移到指针处，拖动滑块保持抓取偏移；滚轮转发给消息区；保留 Home／End／PageUp／PageDown；无障碍角色为 `scrollbar`，文案使用 i18n `chat.minimap`。
+- 验证：minimap、历史窗口和时间线定向测试 65/65；web 类型检查和改动文件 lint 通过；`App.test.tsx` 342/350，8 个失败与此前相同（等待状态圆点异步断言）；`npm run build:bundle` 通过。
+- `npm run perf:app` 通过：长会话打开帧 p95 8.6 ms、无长任务；长会话滚动帧 p95 8.6 ms、无长任务；`stream-seeded`／`stream-and-type` 无长任务、帧 p95 8.5 ms；24 次切换后 DOM 2,449、堆 23 MB，后半段增长 0.1 MB。
+- 未验证：真实鼠标悬停／拖动的视觉效果仍需在桌面端人工确认；多轮交替与低端机模拟仍未做。
+
+### 2026-10-12 第二次交互修订
+
+- minimap 只覆盖阅读区：顶部从 `--chat-context-height`（任务条）开始，毛玻璃模式下再让出 58 px 标题栏；滑块轨道高度取 rail 实际高度，rail 自身尺寸变化由独立 `ResizeObserver` 触发重算。
+- 展开宽度调为 120 px（后续按反馈改为 80 px）。展开视图改为逐行描线：`minimapLines` 按约 72 列折行（CJK 按两列计）、保留空行、代码块缩进并降低不透明度，每条消息最多取 600 行；消息块高度装不下时按行均匀抽样。行剖面按消息对象缓存在 `WeakMap`，流式更新产生新对象时才重算。
+- 验证：定向测试 67/67（新增折行剖面和逐行绘制用例）；web 类型检查与 lint 通过；`npm run build:bundle` 通过。
+- `npm run perf:app` 通过，各场景帧 p95 8.5–8.6 ms；长会话打开、长会话滚动、两个流式场景均无长任务；内存回收与上一轮一致。运行中出现的 renderer error 为网络更新检查 `AbortError`，与本功能无关。
+
+### 2026-10-12 第三次交互修订
+
+- 展开宽度改为 80 px（窄屏仍为 64 px）。
+- 已取消的回复在缩略图中改为助手灰色，与正文状态行一致；只有失败的回复显示红色（复用 `isCancelledMessage`）。
+- 修正滚动时缩略图密度变化：此前每条消息的色块高度取 `MessageRowHeights.size()`，未测量行使用“已测行平均高度”估算；滚动挂载新行后估算值和实测值变化，每次提交都会按新高度重画整张图。现改为双轴：
+  - 绘制轴：`minimapMessageWeight`（折行数 + 3 行头部 + 每个工具 2 行），只依赖消息内容；画布只在消息数组变化（新消息、流式输出）或尺寸、展开状态变化时重画，行测量不再触发重画。
+  - 滚动轴：行高前缀和，仅在 `scrollHeight` 变化时重建。滑块位置和高度按行在两轴之间分段线性映射，覆盖视口内消息在缩略图上的实际区段（最小 16 px）；点击和拖动走反向映射。
+- 验证：minimap、历史窗口、时间线定向测试 69/69（新增“行测量不��发重画”和“滑块对齐可见行的概览区段”用例）；web 类型检查与 lint 通过；`npm run build:bundle` 通过。
+- `npm run perf:app` 连续两次通过。第二次结果：长会话打开、长会话滚动、`stream-seeded`、`stream-and-type` 均无长任务，帧 p95 8.5 ms；24 次切换后 DOM 2,449、堆 23.2 MB，后半段增长 0.2 MB。第一次运行中长会话滚动帧 p95 为 16.6 ms，`stream-seeded` 有 1 个 62 ms 长任务，第二次未复现，按单次噪声记录。
+- 未验证：真实桌面端滚动时的视觉稳定性需人工确认。
+
+### 2026-10-12 外观设置开关
+
+- 新增应用设置 `chatMinimapEnabled`（`z.boolean().default(true)`），旧设置文件缺省时读为开启，无需升级设置版本；`application.update` 配置工具复用同一更新 schema，自动接受该字段。
+- 设置 › 外观新增开关“滚动条缩略图”／“Scrollbar minimap”，位于“透明磨砂特效”之后，保存后立即生效。
+- 关闭时 `ChatHistoryPane` 不挂载 `ChatMinimap`，也不再设置 `data-minimap`，原生滚动条随之恢复；历史窗口（完整已加载消息）和约 60 条 DOM 窗口不变。
+- 验证：设置存储（缺省默认、两种取值的持久化与重载、非法值拒绝）、外观开关（中英文）、窗格开关切换用例均通过；相关 8 个测试文件 410 项中修正配置快照夹具后全部通过；`App.test.tsx` 342/350，8 个失败与此前相同；web／node 类型检查（除既有 `desktop-storage-electron-fixture.ts`）与改动文件 lint 通过。

 # 主机管理与云环境界面设计
 
-状态：2026-09-28 设计，待实现。范围见[PRD](./prd.md)，状态及依赖遵守[功能逻辑](./logic-design.md)。视觉、页面壳层和组件遵守[统一界面设计系统](../../../UI-DESIGN.md)。

 ## 应用入口
 
-应用中心新增“主机管理”和“云环境管理”两个同级应用。应用菜单、管理应用中的“打开”和常驻侧栏入口进入同一主内容区页面，关闭来源菜单或管理 Modal，不在应用中心 Modal 内管理主机。业务页面使用全局范围标识；打开页面不切换当前项目、不连接主机或执行安装。

-通用启用、常驻和排序遵守[应用导航设计](../application-tool-navigation/ui-design.md)。设置中心移除主机操作表单，保留必要的迁移跳转；共享远程能力开关归入主机管理的应用设置。Agent 包下载、导入等现有全局包管理暂留原位置，主机执行环境页提供相关入口，不复制包状态存储。
+通用启用、常驻和排序遵守[应用导航设计](../application-tool-navigation/ui-design.md)。设置中心不再包含“主机与远程执行”分类和“平台功能 > 远程项目”页签。共享远程能力开关只在应用中心的“主机管理 > 应用设置”中，开关文字为“启用远程能力”；业务页面不重复提供设置页签。
 
-## 主机页面
+远程能力关闭时，主机管理仍可从应用菜单和应用中心打开：“主机”页签显示“远程能力未启用”及“启用远程能力”按钮，不调用主机服务；“Agent 离线包”页签照常可用，便于提前下载或导入。
 
-页面使用共享 `dashboard` 壳层。标题区显示“主机管理”、全局范围和主操作“添加主机”。工具栏提供名称或地址搜索、来源筛选、连接状态筛选。列表显示名称、地址、来源、SSH 状态和执行环境摘要，避免每行展开安装表单。
+## 主机页面（一期，已实现）
 
-宽窗口使用列表与详情两栏，点击主机只更新详情，不重排列或滚动列表。详情使用共享 `PageTabs`：
+页面使用共享 `standard` 壳层，标题区显示“主机管理”和全局范围。页签为“主机”和“Agent 离线包”；两个面板切换时保持挂载，安装、下载和导入的进度不中断。离线包页签首次显示时才读取包清单。
+
+“主机”页签顶部是名称或地址搜索和“添加主机”。主机多于一台时，每台主机默认收起为一行，包含：
+
+| 区域 | 内容 |
+| --- | --- |
+| 左侧 | 展开按钮、名称、`用户@地址:端口` |
+| 状态徽标 | 验证状态；已验证时显示执行环境摘要（环境就绪、环境待更新、环境未安装、环境未检查、安装中）；有关联项目时显示项目数 |
+| 右侧 | “编辑”或“验证并保存”、“删除”，均为纯文字按钮 |
+
+只有一台主机时默认展开。安装进行中、安装失败、版本读取失败或正在确认删除时，该主机强制展开且不能收起。保存或重新验证成功后自动展开该主机。展开后显示认证方式、凭据、验证状态、Host Key 指纹、连接结果和执行环境；执行环境的版本以表格呈现，列为“组件 / Host 已安装 / GoodBuddy 所需 / 状态”，悬停版本号显示架构。
+
+删除确认在主机头部下方占满整行，列出会一并删除的关联项目记录，并说明不会连接主机或删除远端内容。展开状态只保存在当前页面，不持久化。
