+- Desktop `0.15.10` unifies project/conversation navigation with ten recent
+  conversations, adds independent Supervisor model selection and a default-on
+  per-conversation Story Graph switch. Indexed activity paging and complete
+  summaries, document Workers, lazy startup, narrower render subscriptions,
+  windowed lists, terminal batching and old Runtime cache cleanup reduce repeated
+  work without promising universal speedups. Schema 58 requires a pre-upgrade
+  database and notes backup. Frequent local writes use NORMAL and can lose a
+  recent suffix on power/system failure; remote acknowledgments, channel delivery
+  and task lifecycle writes retain FULL. Agent stays at 0.15.3. Four real Host
+  model requests and a 1,000-line Unicode SSH terminal check passed; exact-source
+  CI and six native packages remain release gates, and reported remote resume
+  failures are not claimed fixed. See the

+  graph navigation, with schema 56 backup/rollback requirements and possible
+  model costs. Conversation/message windowing, Markdown caching, read-only
+  Workers, incremental activity writes, and checkpoint event batches reduce
+  repeated work without promising universal speedups. In-page find excludes
+  unmounted rows, rapid scrolling can show placeholders, and unavailable Workers

+# GoodBuddy 性能原则
+
+## 文档信息
+
+- **适用范围：** Desktop（Electron Main、Preload、Renderer）及其后台进程和线程。
+- **用途：** 新功能设计和代码评审的约束。多个 agent 并行修改代码时，以本文为统一标准。
+- **关联文档：** `docs/roadmap/product-performance-experience-improvement-plan.md`（测量记录与实施进度）。
+- **参照：** VS Code 的进程分工和渲染做法。我们没有在同一台机器上实测过 VS Code，下面的预算按常见的流畅标准设定。
+
+## 1. 性能预算
+
+“流畅”用下面的数字判断，不靠感觉。“标准机”指不降速运行 `npm run perf:app`，“低端机”指加上 `GB_PERF_CPU_THROTTLE=4`。
+
+| 指标 | 标准机 | 低端机 |
+| --- | --- | --- |
+| 按键到下一帧，p95 | ≤ 16 ms | ≤ 50 ms |
+| 点击到界面响应（切换会话、打开面板），p95 | ≤ 100 ms | ≤ 300 ms |
+| 稳定交互期间（打字、滚动、流式输出）超过 50 ms 的长任务 | 0 | 尽量为 0，总时长不超过场景时长的 5% |
+| 流式输出、滚动时的帧间隔，p95 | ≤ 17 ms | ≤ 33 ms |
+| Main 事件循环单次阻塞 | ≤ 16 ms | — |
+| Main 事件循环延迟，p99 | ≤ 30 ms | — |
+| DOM 节点数 | 不随会话数、消息数增长 | 同左 |
+
+标准机的阈值由 `npm run perf:check` 检查。低端机的数值目前只做记录，等结果稳定后再加进阈值检查。
+
+## 2. 原则
+
+### P1 Main 只做调度
+
+Main 负责窗口、生命周期、权限和消息转发。数据库查询、文档解析、哈希、向量计算、批量文件读写，都放到 worker 线程或 `utilityProcess` 里执行。
+
+- 新代码不能在 Main 里使用 `DatabaseSync` 和同步文件 API。lint 已有白名单，名单只能减少。
+- 暂时必须留在 Main 的同步操作，单次耗时要能证明在 16 ms 以内，并在代码里注明理由。
+- 耗时可能超过 16 ms 的操作，必须支持取消和进度上报，不能一直占着 Main。
+
+### P2 界面状态局部订阅
+
+状态按领域放进外部 store，组件通过 selector 只订阅自己用到的那一部分。
+
+- 不再往 `App.tsx` 里加 `useState`、`useEffect` 或领域逻辑。`App.tsx` 有行数上限，只能往下调。
+- IPC 订阅放在 store 模块里，组件不直接调用 `window.goodbuddy.*.on*`。
+- 一个按键、一个流式片段，只能让显示它的那一小块界面重新渲染。
+- 传给 memo 组件的回调和 context 值，引用必须稳定。
+
+**模块约定（便于维护，所有拆分都按这个结构做）：**
+
+| 层 | 文件命名 | 内容 | 不允许 |
+| --- | --- | --- | --- |
+| Store | `<domain>-store.ts` | `create<Domain>Store()` 返回 `getState / subscribe / 领域动作`；纯 TS，不依赖 React；可单测 | 访问 DOM、调用 React hook |
+| 选择器 / Hook | `<domain>-selectors.ts` 或 `use-<domain>.ts` | 基于 `useSyncExternalStore` 的 selector，返回值引用稳定 | 在 selector 里新建对象却不做相等比较 |
+| 同步层 | `<domain>-sync.ts` | 与 Main 的 IPC：首次加载、订阅推送、增量保存队列、失败重试、退出前刷盘 | 放在组件里；整份数据回写 |
+| 视图 | `<Domain>*.tsx` | `memo` 组件，只从 selector 和稳定的动作读数据 | 接收 App 的大对象或内联回调 |
+
+- `App.tsx` 只负责布局外壳、路由和把 store 实例通过 context 提供给子树。新增领域状态一律走上表四层。
+- 每个 store 的单元测试和 store 文件放在一起（`<domain>-store.test.ts`），覆盖顺序、失败重试和边界情况。
+- Main 侧对应：`<domain>` 的数据库访问集中在一个 repository 类里，IPC handler 只做校验和转发。
+
+### P3 高频数据走专门通道，按帧合并
+
+流式文本、终端输出、进度、滚动这类高频数据，不进全局状态。
+
+- 多条更新合并后，每帧最多提交一次；同步到全局状态的频率要更低，目前是 250 ms。
+- 高频路径上不能读取布局（`getBoundingClientRect`、`scrollHeight` 等），布局读取要集中到每帧一次。
+- 合并更新不能丢失、重复或打乱顺序。每条数据带序号，并有测试覆盖。
+
+### P4 数据只有一份来源，只传变化部分
+
+- 每类数据只有一个权威来源，由数据所在进程负责持久化。界面不把整份数据写回。
+- 跨进程的通知直接带上变化的内容，接收方不再“收到通知后重新查全量”。
+- 写入合并成批次和事务，不按每个事件单独开一个事务。
+
+### P5 工作量和可见内容成正比
+
+- 长列表只渲染可见部分，包括消息、会话、笔记、文件树和知识库列表。
+- 解析和渲染的结果要缓存，比如 Markdown 语法树。内容没变，就不重新计算。
+- 增量处理：只解析变化的部分。没有把握时，退回到慢但正确的完整处理，并记录在测试里。
+
+### P6 启动只做首屏需要的工作
+
+- 首屏之前只做显示应用壳和恢复上次界面所需的工作。
+- 其他初始化（Provider、Runtime、知识库、通知渠道等）按需执行，或等首屏显示后再空闲执行。
+- 后台模块在第一次使用时才加载。
+
+### P7 先测量，再修改
+
+- 先跑测量，拿到数据再改代码；每项改动都要有前后对比，基线用临时 worktree 构建。
+- 每个版本至少跑 3 轮，交替运行；结果差异小于同一版本多次运行之间的波动时，不能说成“有提升”。
+- 测量用隔离的用户目录和本地假模型，不发出外部模型请求，结果里不含用户内容。
+
+### P8 正确性优先于速度
+
+- 事件顺序、持久化、取消、崩溃恢复和显示结果都不能因为性能而改变。
+- 异步改造要先确认“先写入、后读取”的顺序，没有测试覆盖就不合并。
+- 风险高、收益小，或者会改变现有功能的优化先不做，在计划文档里记录理由。
+
+### P10 体验不倒退
+
+性能优化只能让体验变好，不能用体验换速度。“行为不变”不仅指数据和结果，也包括用户能感知到的交互：
+
+- **动画和过渡保持原样。** 平滑滚动（如“到底部”按钮）、展开收起、悬停、淡入淡出都不能因为优化而消失。任何瞬间写入 `scrollTop`/`scrollTo` 的代码都会打断正在进行的平滑滚动，必须在平滑滚动期间暂停。
+- **只渲染可见部分（P5）时，用户状态不能丢。** 行被卸载后，它的局部状态也会消失。以下行必须保持挂载，或者把状态存到行外：有焦点的行、用户展开过 `<details>` 或输入过内容的行、选中文本的两端、待回答的问题和待审批项、打开菜单或正在重命名的行。
+- **只渲染可见部分时，基本操作要和完整列表一致：** 跨行选择和复制、滚动位置不因上方插入或删除而跳动（关闭原生 `overflow-anchor` 时要自己做锚定）、快速拖动滚动条时没有空白帧、渲染结果缓存让重新挂载的行不出现“加载中”。
+- **合并和批处理不能增加交互延迟。** 第一条数据立即处理（leading edge），只合并之后同一帧内的数据。打字回显、终端回显不能多等一帧。
+- **低频同步不能让用户看到旧数据。** 复制、导出、保存这类读取全局状态的操作，要先把待同步的数据刷进去。
+- **体验要有测试。** 涉及动画、滚动、焦点的改动，需要真实 Electron 测试（逐帧采样）或单元测试，并确认测试在旧代码上会失败。
+
+### P9 用工具守住规则
+
+- lint 规则和性能阈值是合并前的硬性条件，不靠人工记得。
+- 规则只能收紧，白名单和上限只能往下调。
+- 每个 agent 只提交自己改的文件和片段，不把别人未提交的改动带进自己的提交。
+
+## 3. 评审清单
+
+提交性能相关改动，或者会影响热点路径的功能改动时，逐项确认：
+
+1. Main 里有没有新增同步数据库调用、同步文件 IO，或者耗时可能超过 16 ms 的计算？

+4. 有没有整份数据回写，或者“收到通知后重新查全量”？
+5. 列表的 DOM 数量会不会随数据量增长？

+7. 是否附上了 `perf:app`、`perf:main` 或 `perf:knowledge` 的前后对比？
+8. 顺序、取消、持久化和恢复，有没有测试覆盖？

+## 4. 当前差距
+
+截至 2026-10-04（第一期结项，见 `docs/review/performance-phase-1-report-2026-10-04.md`），按原则对照的主要差距：
+
+| 原则 | 差距 |
+| --- | --- |
+| P1 | 同步数据库调用仍在 Main，没有独立数据进程；但热点读已在 worker，高频写单次 0.1–0.3 ms，WAL checkpoint 在后台线程，启动恢复按索引读取。文档解析、分块和大文件哈希已移到 worker。消息附加数据冗余（子任务工具输出、`tools` 与 `blocks` 重复），大会话读取约 170 ms |
+| P2 | `App.tsx` 约 7,900 行。输入区、隐藏路由、任务和结果事件、切换会话已不再整体重渲染 App；当前会话的流式吸收（每 250 ms）、队列和活动记录仍经过 App |
+| P3 | 已基本满足：流式输出和终端输出都已按帧合并 |
+| P4 | 活动记录已改为增量保存、按页读取（界面只保留已加载的页，计数和分组来自 Main 的汇总）；部分 `*Changed` 通知之后还会重新查全量 |
+| P5 | 已基本满足：消息、会话、笔记、文件树、知识库文档表格都只渲染可见部分 |
+| P6 | 空配置启动到输入框可用约 0.96 秒；真实数据（2.4 GB）约 1.36 秒。本地工具环境已后台初始化，低频模块按需加载 |
+| P9 | 性能阈值还没有接入 CI，也没有真实低端机的基线 |

+# Desktop 0.15.10 发布准备
+
+日期：2026-10-04。基线 `v0.15.9`，冻结已提交源码
+`74efbcdc1703e6893764dbb2c48e3d1c47b21fce`，35 个提交。
+仅纳入已提交实现和发布准备，保留并排除工作区中的导航、文档处理等并行修改。
+标准六平台 Desktop，不含 LoongArch；Agent 保持已发布的 0.15.3。
+
+## 范围与兼容性
+
+- 统一项目与会话菜单、当前/全部范围、活动及十个最近会话、悬停预览。
+- 监督者独立文本模型选择及默认开启的会话 Story Graph 开关。
+- 活动差量保存、索引分页与完整汇总，schema 57 保留历史并迁移排序；
+  schema 58 增加启动恢复候选消息索引。升级前关闭应用并备份完整数据库
+  和相邻 notes 目录，旧客户端回退须恢复升级前备份。
+- 文档解析 Worker、依赖延迟加载、本地工具环境后台准备、Composer 和
+  路由等渲染边界、笔记/文件树/知识文档窗口化、滚动和焦点保留。
+- 终端 Main 合并与 xterm 帧批次，远程事件 16ms 定时 flush；
+  checkpoint 前落库、事务顺序和回放去重保留。
+- 旧 Runtime 缓存按明确版本和布局命名清理，跳过符号链接；
+  保留当前布局、运行记录、会话和配置。工作栏间距及操作修复。
+- 高频本地写入临时切换 NORMAL 并恢复原 PRAGMA；嵌套事务由外层决定。
+  保留应用崩溃原子性，但断电/系统崩溃可能丢失最近部分本地写入。
+  远程确认、通道投递和任务生命周期继续 FULL，后台 PASSIVE checkpoint
+  不代表已经验证破坏性断电恢复。
+- Agent 守护进程只有测试变更，Continue host-v7 仅提取常量，协议和部署
+  行为未变，因此不发布新 Agent。Electron/Node/OpenCode/Continue 锁不变。
+
+不承诺通用提速比例。窗口化未挂载行不支持页内查找，快速滚动可显示占位；
+只读 Worker 失效可同步回退。开发报告中的 stable controller generation resume
+及 Runtime 未到终态错误仍是调查项，本轮不声称修复。
+
+## 本轮真实 Host 验证
+
+中断前已针对 `e89db96` 源码使用固定 Host 身份与既有凭据存储，
+在隔离测试目录经生产 Agent、模型桥、远程 ACP、RemoteEventBatcher
+和 SQLite 持久化入口执行。后续 `74efbcd` 仅修改工作栏 CSS 间距，
+不改变已验证的远程实现。OpenCode 探针显式使用已有 Continue 模型配置，
+不是产品静默回退；未构建生产安装包。
+
+**4 次真实模型请求，4 次 HTTP 200**：
+
+| Runtime / 模式 | 批次 | 事件 | checkpoint |
+| --- | ---: | ---: | ---: |
+| OpenCode Ask | 3 | 4 | 2 |
+| OpenCode Execute | 22 | 42 | 21 |
+| Continue Ask | 3 | 4 | 2 |
+| Continue Execute | 21 | 40 | 20 |
+
+checkpoint 前落库、完整已保存流再次写入返回已存在、Runtime 重建后历史恢复，
+本轮拥有进程清零。生产 SSH 连接池与终端会话另输出 1000 行 Unicode，
+13 个输出事件；CRLF 归一化后内容完全一致、序号递增、输出先于退出。
+最初终端探针选错 Host 路由，发生在模型请求前，真实调用数为零；
+随后复用成功固定的路由完成。临时 Electron 缓存警告非致命，不算产品修复。
+
+这些证据不是完整 Renderer、已安装 Agent 升级或全部断线恢复矩阵，
+也没有验证所有消息投影恢复分支。开发阶段其他模型调用不计入本轮四次。
+
+## 发布门槛
+
+按用户持续授权，直接提交、推送并跟进 CI 和发布，不逐步询问。
+不运行本地测试套件、类型检查、lint 或生产构建；完整验证和构建由精确候选
+main CI 执行，通过后才创建新的不可变 Desktop 标签。双语说明与 FEATURES
+同时更新；Agent 不打新标签。开发文档记载的未通过测试不能视为已解决，
+由此次精确候选 CI 决定，失败须定位修复。
+
+最终需核验六平台打包、macOS 签名与公证、GitHub Latest 和 20 项资产、
+北京 OSS 索引一致性与网站 12 种下载选择。不下载或启动安装包，
+不将候选或推送成功称为发布完成。
+
+### 首轮候选 CI
+
+`273a7fa` 的 Desktop CI `37174433765`：5953 通过、59 跳过、3 失败，
+生产构建未执行；Agent CI `37174433777` 通过。
+监督设置测试需要先进入“回顾整理”页签再操作其可见保存按钮，
+Electron 布局测试更新为真实标题“模型与运行限制”，截图锚点限定可见设置面板。
+保留保存值、再次打开恢复、布局及溢出断言。
+1200 条活动历史测试会实际显示至 1000 行，专用超时从 30 秒改为 60 秒；
+不减少数据、不移除分页、清空总数或离页裁剪断言，等待下一次 CI 验证。
+
+`362fe50` 的 CI `37175597089`：上述三个测试均通过，5955 通过、59 跳过；
+另一个工作区 KeepAlive 测试在默认一秒内未找到魔法笔记标题。
+仅将该轮换测试的异步标题等待设为五秒，保留聊天 DOM 身份、旧工作区淘汰
+及缓存数量断言。CI 观察命令曾出现 GitHub API EOF，最终失败以工作流结果为准。

+- Execute 配置工具不再重复弹原生确认，Ask 只读边界不变。
+- Electron 44.5.1；Node、OpenCode、Continue 锁不变。
+- Agent 虽无守护进程文件变更，但打包的 Story Graph 工具 schema 增加 story/experience，
+  旧 Agent 不支持这些输入，因此升级 0.15.3，最低 Desktop 0.15.9。
+
+性能范围及暂缓项见[性能计划](../roadmap/product-performance-experience-improvement-plan.md)。
+不把组件或特定机器的指标作为普遍提速保证；向量仍可全表扫描，Worker 失效会同步回退，
+窗口化的未挂载行不支持页内查找，快速滚动可能短暂显示占位。
+故事、经验、建议与输出重试有模型费用，自动结果须人工核对。
+
+## 本轮真实 Host 验证
+
+当前源码临时打包到隔离测试目录，不构建生产安装包。使用现有固定 Host 身份及
+凭据存储，通过生产 Agent Attach、模型桥及远程 ACP 路径执行 OpenCode 与 Continue
+各一次 Ask、一次 Execute。OpenCode 探针显式选择既有 Continue 模型配置，
+不修改产品设置，也不是产品静默降级。
+
+共 **4 次真实提供方请求，4 次 HTTP 200**，无模拟推理、无自动请求重试。
+验证 Runtime 释放后重建、历史恢复和本轮进程清零。
+每次消费真实远程语义流，通过生产 `RemoteEventBatcher` 与
+`AssistantDatabase.appendRemoteTaskEventsOnce` 在 checkpoint 前落库；
+对完整已提交事件再次写入均返回已存在。四次请求分别记录：

+| OpenCode Execute | 21 | 40 | 20 |
+| Continue Ask | 3 | 4 | 2 |
+| Continue Execute | 23 | 44 | 22 |
+
+验证没有启动完整 Renderer，也不声称覆盖会话消息投影的所有恢复分支。
+Story Graph 新对象与来源语义由本轮源码测试及开发记录覆盖，以上四次请求不调用图谱工具。
+开发文档中的模型调用不计入本轮 4 次。临时探针的两次编译钩子定位失败均发生在请求之前。
+
+## 发布门槛
+
+按用户要求，不执行本地测试套件、lint、类型检查或生产打包；
+精确候选推送双远端后由 CI 做全量验证和生产构建，再打不可变双版本标签。
+中英文 FEATURES 需同步共享进度、已实现故事经验、成本和窗口化限制。
+公开核验 Desktop Latest、标准产物、Agent 签名目录、两个源及网站，保留任何并行未提交工作。

+### 长会话验收
+
+`npx jiti scripts/long-session-acceptance.mjs <live.sqlite> .env.deepseek.local <dir> <会话前缀> [failAfter]`：对本机数据库做在线备份，只在副本里归档其他会话、隐藏任务，使回顾只读取一条真实会话；首次运行在第 N 次提取时注入一次提供方失败（不消耗付费调用），再继续同一回顾；完成后用保存的批次片段逐条重建每条消息原文；最后再跑一次心跳和一次默认手动回顾，要求零模型调用。原库不修改。
+
+第一次跑最长会话（389 条消息、约 21.7 万码点、16 天）时，继续回顾三次都失败：两次是模型返回无效 JSON，一次是引用了范围外的来源。原因是一个批次的模型输出不可用时整次回顾立即失败，只能靠反复手动“继续”碰运气。改动：
+
+- 叶子批次输出不可用（无效 JSON、结构不符、引用不存在的来源或实体）时，在同一段待处理正文上缩小到 1/2、再到 1/4（不少于 500 字符）重试，最多 2 次；缩小只是先处理前一部分，其余正文留在待处理里，不跳过、不截断。
+- 导航合并输出不可用时，用相同输入再问 1 次。
+- 提供方错误、超时、取消和响应超出容量不重试，仍按原来的方式失败并保留已保存批次。
+
+改后结果（DeepSeek `deepseek-flash`）：
+
+| 会话 | 首次运行 | 继续 | 覆盖 | 无变化重跑 |
+| --- | --- | --- | --- | --- |
+| 97 条、6.0 万码点、4.9 天 | 第 4 次提取注入失败，已存 3 批 | 1 次完成，16 次调用 | 97/97 条精确重建，0 缺口、0 重叠 | 心跳、手动均 `no_change`，0 调用 |
+| 389 条、21.7 万码点、16.2 天 | 第 7 次提取注入失败，已存 5 批 | 1 次完成，61 次调用（30 提取、31 合并），约 32.5 分钟 | 389/389 条精确重建，0 缺口、0 重叠 | 心跳、手动均 `no_change`，0 调用 |
+
+最长会话共 67 次调用、约 52.7 万输入和 54.8 万输出 Token，发布 237 个事件；失败前保存的批次在继续后全部保留未重算。改动前的同一会话运行（三次继续均失败）记录在 `sl9/long2`，改后中间版本（仅叶子重试，合并失败两次后第三次继续完成）在 `sl9/long3`。
+
+边界：完整覆盖只说明每段原文都进入了成功批次，不代表模型没有遗漏或误读；验收只用了两条会话，没有测多项目全局回顾。
+
+### Agent 自主调用
+
+决定：普通对话不自动注入故事和经验，由 Agent 按需调用 Story Graph 工具。为此：
+
+- 工具说明写明何时应主动调用（继续之前的工作、询问为什么这样决定、在可能有既有约束的领域开始新任务）、何时不调用（闲聊、与项目历史无关的通用问题），用 2～4 个关键词查询，查几次找不到就说明并按当前上下文回答。
+- 搜索改为按词匹配：空格和标点分词，中文按相邻两字切分；一条记录命中整句或至少一半的词即返回，按命中程度排序，故事和经验在同分时靠前。此前 Agent 用“监督者回顾调度”这类自然短语搜索，因为要求整句出现而 0 结果。
+- 搜索结果的预览先显示名称、标题、描述等可读字段，不再以 ID 开头。
+
+验证（`scripts/story-graph-agent-deepseek.mjs`，DeepSeek 函数调用，只给生产工具定义，不提示要用工具）：
+
+| 轮次 | 判断正确 | 说明 |
+| --- | --- | --- |
+| 改前 | 4/5 | 通用编程题也去搜索；继续工作类问题搜了 9～22 次仍找不到内容 |
+| 改后 | 5/5 | 三个项目历史问题都主动调用；数组去重和问候都不调用 |
+
+改后“继续回顾调度，按最后定的方案”能找到并引用 2026-10-02 的故事线模型设计；“导出功能有什么约束”能列出经验和来源。“为什么取消 300 秒自动暂停”仍在搜了十几次后达到对话轮数上限：这次取消发生在数据副本最后一次回顾之后，图谱里确实还没有这条决定，Agent 没能及时停止并说明“没有记录”。
+
+## 2026-10-02 故事与经验质量抽查
+
+数据：同一份 437 个事件的数据副本上已有的故事归属运行（`sl3/off1`、`sl3/cross2`）和经验抽取运行（`sl4/run1`、`sl4/run2`），以及本次改提示词后的新运行（`sl8/off3`，DeepSeek `deepseek-flash`，12 次调用，约 6.2 分钟）。一致性用“两次运行中同属一个功能的事件对”的重合度（Jaccard）衡量。
+
+| 检查 | 结果 |
+| --- | --- |
+| 故事归属一致性（改前，off1 对 cross2） | 0.51 |
+| 主要不一致来源 | “提交与发布”吸收了 87 个事件，其中只有 40% 在另一次运行里属于发布；其余是各功能自己的提交、推送和验证 |
+| 改动 | 提示词明确：某个领域的提交、推送、测试和验证属于该领域；发布功能只放版本号、发布说明、标签、打包和发布 |
+| 改后（off3） | 发布功能 42 个事件；与 cross2 的一致性 0.74；暂不归类 55 个；再次整理 0 次调用 |
+| 暂不归类的事件 | 抽查 cross2 的 49 个：几乎都是问候、知识截止时间、SSL/认证报错、寿命和睡眠问答、案例咨询、权限挂载等一次性问题，归为“暂不归类”是合理的 |
+| 经验跨运行一致性 | run2 的 38 条里 23 条能在 run1 中找到形成依据重合（Jaccard ≥ 0.3）的对应经验，表述基本一致 |
+| 经验依据抽查（10 条） | 形成依据基本都对得上经验内容；后续“应用”较弱，抽到的 5 条应用里约 2 条和经验关系不大（例如“需求有歧义先确认”被记到“询问微信附件导入能力”） |
+
+结论：功能边界在明确“提交归领域”后明显稳定；仍有约四分之一的事件对在两次运行间归属不同，主要发生在界面、笔记、帮助提示等相邻功能之间，可以通过手动合并修正。经验的形成依据可信，应用记录原先过宽。
+
+随后收紧经验应用：模型给出的应用事件必须与该经验的某个形成事件共享实体，否则丢弃（同批其他内容保留）。在 off3 的故事上重新抽取（6 次调用，约 3.8 分钟）：45 条经验，应用记录从此前的 53 条降到 6 条，抽查 6 条全部与经验内容相符；依据无来源 0、应用早于形成 0、再次抽取 0 次调用。代价是跨故事的经验连线变少（3 条），时间螺旋和“可用经验”建议能显示的跨故事复用也随之减少。`supervision-experiences.test.ts` 新增“无关知识的事件不记为应用”。

+- 时间螺旋：经验画成桶外的菱形，高度在形成与应用两个时间之间，角度在两片木片之间；两段向外弯的弧线分别连到形成木片和应用木片的对应高度。只有选中的经验在画布上显示名称。提供“跨木片的经验”键盘入口（现为工具栏选择框）；点击菱形或选择经验打开详情。
+

+
+- 工作回顾在所选回顾结果的摘要之上新增“这段时间的故事”，按该结果的范围和时间区间读取已保存的故事和经验，不调用模型（`supervision-story-digest.ts`、`SupervisionStoryDigest.tsx`）。
+- 分组：推进的故事（区间内有事件、区间前也有）、新出现的故事（第一个事件在区间内）、已结束的故事（结束依据事件在区间内）、形成或用上的经验（最早形成依据在区间内，或区间内有应用）、这段时间没有新进展（进行中、区间前有事件、区间内没有；跨项目故事和已结束的故事不算）。功能把子线索的事件计入自己，子线索不重复列出。
+- 每组按事件数排序，默认显示 6 条，可展开其余；每条显示项目、事件数和最近一个事件。点击任一故事或经验打开图谱，并选中该对象。原有的工作总结、本次变化、未解决事项保留在下方，作为阅读入口。
+
+验证：
+
+- `supervision-story-digest.test.ts` 2 项（分组规则、子线索计入功能、跨项目与已结束故事不算无进展、经验形成与应用区分）；`SupervisorWorkspace.test.tsx` 新增 1 项（按所选结果范围读取故事、各分组内容、点击进入图谱）。相关组件测试 4 个文件 73 项通过，Web 类型检查、相关 ESLint 通过。
+- Electron 实测（生产组件，第 5 步数据副本导出的 46 个故事、38 条经验和一条 7 天的全局回顾结果；1440 浅色、1024 深色、390 深色）：无报错、无横向溢出、条目无文本溢出；宽屏 3 列、窄屏 1 列；展开后从 13 条到 26 条；点击条目切到图谱。该副本的数据从 09-19 开始，这条结果的区间正好覆盖全部数据，因此只出现“新出现的故事 19”“已结束的故事 1”“形成或用上的经验 33”，“推进的故事”和“没有新进展”两组没有在真实数据中出现，只由单元测试覆盖。

+
+对应[故事线模型改造设计](./storyline-model-design.md)第 5 步。工作回顾页按故事组织见上一节。
+
+实现：
+
+- 心跳建议新增两类，候选只由规则选出，不调用模型：
+  - **暂无进展**（`stalled`）：本次范围内进行中的功能或子线索（至少 3 个事件），最近事件距今达到“故事多少天没有新进展时提醒”（设置，默认 14 天）。只提示查看，不改变故事状态，不推断结束。每次心跳最多 3 条，按事件数从多到少；已待处理或依据未变的不计入名额，其余留到后续心跳。接受后转为暂停的后续任务。
+  - **可用经验**（`experience`）：本次回顾归入某故事的事件，与某条经验的形成事件共享实体，而该经验尚未在这个故事中形成或应用。出现在 5 个以上故事中的实体（如产品名）不作为依据。每条经验只指向匹配事件最多的一个故事，每次心跳最多 3 条，按依据数排序。接受即标记已参考。
+  - 两类候选排在未决事项之前，不会被每次 20 条的上限挤掉；与其他建议一起只用一次模型调用措辞，输入不含来源原文和定位。
+- 建议记录 `story_id`、`experience_id`；“在图谱中查看”直接打开对应故事或经验。Schema 56 重建 `supervision_suggestions` 以扩展类型约束，已有行原样复制。
+- Story Graph MCP：`story_graph_search` 支持 `story`、`experience` 两种对象；`story_graph_get_context` 对故事返回其事件（功能包含子线索的事件），对经验返回形成与应用事件，再通过事件读取来源。经验带 `automatic` 或 `user_edited` 标记，工具说明要求把经验作为参考而非规则。查询范围规则不变：项目范围只返回本项目的故事，以及在本项目形成或应用过的经验。
+
+验证：
+
+- 新增 `supervision-story-suggestions.test.ts` 5 项：暂无进展的阈值、不改故事状态、不重复、转任务；每次最多 3 条且按事件数排序、其余在后续心跳补上；经验跨故事建议只出现一次、不建议给形成它的故事；MCP 故事与经验的搜索、上下文及项目范围隔离；Schema 55 升级到 56 保留已有建议。新增 `SupervisionSuggestionsPanel.test.tsx`：新类型标签与按故事、经验打开图谱。监督相关主进程 11 个文件 73 项、IPC 定向 21 项、组件 4 个文件 72 项通过；Node/Web/Agent 类型检查、相关 ESLint 通过。未运行全量测试。

+## 2026-10-02 故事线模型第 4 步：经验抽取
+
+对应[故事线模型改造设计](./storyline-model-design.md) SL-4、SL-5 和第 4 步。
+
+实现：
+
+- `supervision-experiences.ts`：新表 `supervision_experiences`（经验、适用条件、边界、状态、用户调整标记）、`supervision_experience_events`（`formed` 形成依据、`applied` 后续应用及结果）、`supervision_experience_seen`。Schema 55，升级后表为空，由下一次回顾从已有故事中抽取，不重读来源。
+- 在故事归属之后、同一回顾名额内执行。候选由规则选出，不调用模型：有尚未处理的决定、变化或里程碑事件，且事件数达到“故事参与经验整理的最少事件数”（设置，默认 5）的功能或子线索。小故事和只有讨论的进展直接标记已处理，不调用模型。
+- 候选故事按文本量分块，每块一次模型调用，输入是故事名、事件标题与截断描述以及已有经验，不含原文。回答中的每条形成依据必须是本次输入、且有来源的事件，否则整块不保存；早于经验形成时间的“应用”被丢弃（真实模型会出现这种引用），其余保留。同一表述的经验合并到已有经验。
+- 经验生成后即可读取，标记“自动归纳”。用户可以编辑、合并、删除，与故事调整共用撤销；编辑过的标记“已手动调整”；删除的经验不会因同一表述或相同依据再次生成。
+- 经验抽取失败不影响故事和已发布的回顾：活动记录显示“故事已整理，经验整理失败”，可与故事一起重新整理，下一次回顾也会补上。
+- 界面：图谱左侧新增“经验”页签；选中经验在右侧查看适用条件、边界、形成依据和后续应用（含所属故事与结果），依据事件可直接打开；编辑、合并、删除、撤销。设置新增“故事参与经验整理的最少事件数”。
+
+验证：
+
+- 新增 `supervision-experiences.test.ts` 4 项：规则候选、应用记录、无新进展零调用、小故事与纯讨论零调用、虚构依据整块拒绝、早于形成的应用被丢弃、编辑保护、删除后不再生成、合并与撤销。工作区新增经验页签测试。监督相关主进程测试 7 个文件 174 项、工作区／活动／设置组件测试 48 项通过；Node/Web 类型检查、相关 ESLint 通过。未运行全量测试。
+- 真实数据（第 2 步跨项目开启运行后的数据副本，46 个故事，`npx jiti scripts/experiences-deepseek.mjs`，DeepSeek `deepseek-flash`）：
+
+| 运行 | 候选故事 | 调用 / 耗时 | 经验 | 应用记录 | 跨故事经验 | 依据无来源 | 应用早于形成 |
+| --- | --- | --- | --- | --- | --- | --- | --- |
+| 首轮（应用早于形成时整块拒绝之前的规则） | 31 | 6 / 约 3.9 分钟 | 40 | 71 | 15 | 0 | 5 |
+| 修正后 | 31 | 6 / 约 2.7 分钟 | 38 | 53 | 9 | 0 | 0 |
+
+  - 两次再次抽取均为 0 次调用；所有请求都不含来源原文。
+  - 修正后 38 条经验中 8 条只有 1 个形成依据。内容基本是这段时间真实形成的工作经验，例如“长材料回顾须完整分块，按成功批次保存进度并支持续作，禁止截断”“能力开关关闭时须阻断后台任务领取与执行，不能只隐藏入口”“提交只纳入本次相关改动，其他未完成改动留在工作区”。
+  - 两次运行的经验条目不完全相同，未比较多次运行的一致性；也未逐条人工核对每条经验与依据是否对得上。
+
+边界：经验尚未接入 MCP、心跳建议和时间螺旋视图（桶外经验节点），这些属于第 5 步和视图后续工作。
+
+## 2026-10-02 故事线模型第 3 步：时间螺旋视图
+
+对应[故事线模型改造设计](./storyline-model-design.md)第 3 步与 [3D 概念](../story-graph/3d-concept.md)。
+
+实现：
+
+- 图谱画布标题右侧新增“平铺 / 时间螺旋”切换。时间螺旋视图（`StoryGraph3D.tsx`）读取故事列表与图谱返回的 `attention`：高度为时间，半径为每圈的对话轮次（一圈一个半径，相邻圈差值受限），木片为故事起止，事件按屏幕距离聚合。层级为 全部 › 项目 › 功能 › 子线索，跨项目故事在根层；点击木片进入下一层并在右侧显示故事详情，单个事件选中后显示事件详情。斜俯视／侧视／俯视／自由视角，拖动、滚轮、方向键、数字键、Esc。
+- 计算部分在 `story-graph-3d-model.ts`（树、角度、圈长、半径、聚合），渲染只负责显示。圈长从候选档位中选最接近 8 圈且不超过 14 圈的一档。
+- Three.js `0.186.1` 作为依赖，组件通过 `lazy` 加载，只在打开时间螺旋时下载（生产构建中只出现在 `StoryGraph3D` 分块）。颜色取现有 `--graph-node-*` 令牌。WebGL 不可用时提示改用平铺视图。
+- 2026-10-02 布局调整：画布下方的图例段落和木片、经验列表移除，中间区域只保留图。图例改为工具栏“图例”按钮，点击后浮在画布右上角，可用 X 关闭；圈长（如“一圈 1 天 · 共 13.1 圈”）常驻画布左下角。木片和经验的键盘与读屏入口改为工具栏中的两个选择菜单（共享 `AnchoredMenu` 样式，每项显示名称和事件数、起止或来源→去向）。按钮按当前层级命名，如“项目与跨项目故事 · 6”“功能 · 15”“子线索 · 9”“经验 · 3”，不再使用“木片”这一内部比喻。菜单内边距 4px，菜单项 8px×12px、行间 2px，两个按钮间距 8px；1440 与 390 宽度下文字无裁切，菜单在窗口内。
+- 2026-10-03 图谱中间列不再滚动：平铺与时间螺旋都把标题栏以外的高度全部给图。平铺视图的图例、阅读说明移入标题栏“图例”浮层，可见数量常驻画布左下角；“事件浏览”改为单行（上一个、滑块、下一个、位置、当前事件）。图谱行最低 660px，以免平铺图文字小于 11px；更矮的窗口改为页面滚动。Electron 布局测试新增断言：中间列 `overflow: hidden` 且无溢出，图区一直延伸到列底部；1440×1200 下整页无滚动、底部留 33px，图高 625px。真实数据副本下时间螺旋在 700px 行高中填满，无列内滚动。
+- 2026-10-03 图谱页顶部的“图谱范围 · 全局”和时间行并入画布标题下方一行（范围 · 时间区间 · 生成时间 · 事件/实体数），刷新改为标题栏图标按钮；标题由“工作的来路”改为“事件与知识”。图谱行因此多出约 40px：1440×900 下整页不再滚动，图高 552px。布局测试新增断言：范围行位于标题下方，图谱上方不再有独立的范围栏。
+- 2026-10-03 修复“时间螺旋没有加载成功”：每次重建场景都复用同一个画布，而上一次释放时已对它调用 `forceContextLoss()`，该画布再也拿不到可用的 WebGL 上下文（Three.js 报 `Cannot read properties of null (reading 'precision')`）。开发模式的 StrictMode 双挂载、父组件刷新时传入新的 `attention` 数组都会触发重建，所以打开就失败。现在每次重建创建独立的绘图画布并在释放时移除，原画布只负责焦点和指针事件；`attention` 按内容保持稳定，刷新不再重建场景。复现脚本（StrictMode + 20 次父组件重渲染）修复前首屏即报错，修复后无报错。真实数据副本的 Electron 检查（1440 浅色、390 深色）：画布外无段落和列表，图例浮层位于画布内，选择框逐层打开、视角切换、Esc 返回正常，无报错和横向溢出。
+
+验证：
+
+- `story-graph-3d-model.test.ts` 4 项（树与跨度、圈长档位、每圈一个半径且变化有界、聚合）；工作区、活动、设置组件测试通过；Node/Web 类型检查、相关 ESLint 通过；`electron-vite build` 确认 Three.js 只在懒加载分块中。
+- Electron 实测（第 2 步跨项目运行的真实故事数据副本，生产组件）：1440 浅色与 390 深色均无控制台错误、无横向溢出；画布非背景像素约 26%；根层 6 片（5 个项目、2 个跨项目故事中的果蝇神经仿真等），goodbuddy 15 个功能，监督者 9 条子线索；视角切换、Esc 返回、选中故事回调正常；旋转一帧约 1 ms。数据跨 13 天，一圈 1 天共 13.1 圈。
+
+边界：时间切面（第 7 项）、展开视图（第 8 项）、原位分裂动画和桶外经验节点尚未移植；经验（W）要到第 4 步。Three.js 懒加载分块约 1.15 MB。
+
+## 2026-10-02 故事线模型第 2 步：故事归属与用户调整
+
+对应[故事线模型改造设计](./storyline-model-design.md) SL-1～SL-3、SL-5、SL-8 和第 2 步。
+
+实现：
+
+- `supervision-stories.ts`：新表 `supervision_stories`（功能、子线索、跨项目故事，状态、用户调整标记）、`supervision_event_stories`（主故事唯一，另可关联）、`supervision_story_assigned`、`supervision_story_edits`。Schema 54；升级后表为空，已有事件由下一次回顾归属，不重读来源。
+- 回顾发布后在同一回顾名额内执行故事归属：只取本范围中尚未归属的当前事件，按项目分块，每块一次模型调用，输入是事件标题、描述和本项目已有故事摘要，不含原文。没有待归属事件时不调用模型。项目来自事件来源；功能、子线索由模型提出；允许“暂不归类”。
+- Main 校验每个事件恰好分配一次、主故事属于本项目、子线索有上级功能、结束标记引用本次归入该故事的事件；任一项不符则整块不保存。功能事件数低于“子线索最少事件数”（设置，默认 20）时，子线索并入功能。
+- 跨项目关联关闭时，提示词禁止跨项目故事，也不提供已有跨项目故事；开启时项目依次处理，跨项目故事只作关联，不影响主故事的长度和事件数。
+- 用户调整：重命名、合并（同项目同层级）、移除（事件回到上级功能或变为暂不归类，不删除事件）、把事件移到同项目其他故事或暂不归类、撤销上一次调整。调整过的故事不会被自动整理改名或标记结束，移除的故事不会因同名再生成。
+- 故事归属失败不影响已发布的回顾：活动记录显示“回顾已保存，故事整理失败”并可重新整理；下一次回顾（含无变化）也会补上。
+- 界面：图谱左侧新增“故事”页签，按项目 › 功能 › 子线索、跨项目故事列出，显示暂不归类的事件数；选中故事在右侧查看起止、状态、事件，并可重命名、合并、移除、撤销；事件详情可改所属故事。设置新增“功能拆分子线索的最少事件数”。
+
+验证：
+
+- 新增 `supervision-stories.test.ts` 6 项：归属与无变化零调用、长时间空白后接回原故事、不完整／重复／虚构／证据不符的回答整块拒绝、小功能子线索并入、跨项目开关、调整保护与撤销、回顾内执行及失败后重试。`src/main/assistant` 全目录、Story Graph MCP 集成、监督相关 IPC、监督者工作区／活动／设置组件测试均通过；Node/Web 类型检查与相关 ESLint 通过。未运行全量测试。
+- 真实数据（第 1 步升级后的本机数据副本，`scripts/stories-deepseek.mjs`，DeepSeek `deepseek-flash`）：
+  - 跨项目关闭：437 个当前事件，11 次调用约 4.3 分钟；39 个故事（35 个功能、4 个子线索），396 个事件归入，41 个暂不归类；无事件有两个主故事、无主故事跨项目；11 个“已结束”均引用本故事内的事件；再次归属 0 次调用。
+  - 跨项目开启：11 次调用约 6.4 分钟；44 个故事，其中 1 个跨项目故事关联 dgx 与阿里云-国内的 7 个事件；其余检查同上。
+
+观察到的问题（首轮）：
+
+- 功能粒度不稳定：goodbuddy 的发布被拆成 0.13.10、0.13.11、0.13.12、0.13.13 多个功能，两次运行切分不同。
+- 监督者相关 77～85 个事件的功能只拆出 0～1 个子线索，模型很少主动建子线索。
+- goodbuddy 的 fly-brain 仿真与微信 ClawBot 的果蝇开源项目在开启跨项目后仍未关联。
+- 故事起止跨度可以从事件计算，但单个事件的跨度仍多为同一时刻（见第 1 步边界）。
+
+针对上述问题的调整：
+
+- 提示词写明粒度：功能是持续数周的模块、子系统或研究主题；发布、版本、单个缺陷、单日任务不是功能，同一项目的发布与版本同步归入一个功能，版本可作子线索；功能名不含版本号和日期；每个项目通常 3～12 个功能；功能达到“子线索最少事件数”后按子线索放置事件。
+- 新功能或跨项目故事的名字去掉版本号、日期后与已有或同批故事相同时，并入已有故事（确定性规则）；被并入那一方的“已结束”标记不生效，避免一个版本结束让整条发布线结束。
+- 子线索拆分：每个项目归属完成后，自身事件数跨过“子线索最少事件数”下一个整数倍的功能（每项目最多 3 个）各做一次拆分调用，输入只有该功能名称、已有子线索和模型放置的事件标题与截断描述。只把事件从功能移到子线索；新子线索至少需要 max(3, 阈值/5) 个事件，否则不建；用户移动过的事件和用户调整过的功能不动；被用户移除的同名子线索不重建。功能没有跨过下一个整数倍时不再调用。
+- 跨项目开启时，提示词附带其他项目的功能名称、描述和事件数（最多 60 个，不含事件内容），已有跨项目故事附带它已关联的功能名称；回答可用 `links` 把本项目功能和其他项目功能挂到同一个跨项目故事，关联该功能的全部当前事件（只作关联，不改主故事）。关闭时不提供，且 `links` 会被整块拒绝。
+- 新故事键接受 `new_1_t1` 这类写法（真实模型在一次回答中这样写子线索键，原先整块被拒）。
+
+调整后的真实数据（同一数据副本，DeepSeek `deepseek-flash`，每次各自从空故事开始）：
+
+| 运行 | 调用 | 功能 / 子线索 / 跨项目 | 归入 / 暂不归类 | 拆分移动 | 版本号命名的功能 |
+| --- | --- | --- | --- | --- | --- |
+| 首轮 关闭 | 11 | 35 / 4 / 0 | 396 / 41 | — | 有（0.13.10～0.13.13） |
+| 首轮 开启 | 11 | 35 / 8 / 1 | 407 / 30 | — | 有 |
+| 调整后 关闭 | 12（含 1 次拆分） | 19 / 23 / 0 | 372 / 65 | 18 | 0 |
+| 调整后 开启 | 12（含 1 次拆分） | 21 / 23 / 2 | 388 / 49 | 20 | 0 |
+
+- 改善：goodbuddy 发布收敛为一个“发布与版本”／“提交与发布”功能，版本工作成为其子线索；监督者功能拆出 9～11 个子线索（回顾整理与图谱、回顾算法与并发设置、故事线模型与 3D 图谱、活动记录页、自动监督开关与设置等），界面、笔记与画布也拆出子线索；开启跨项目后“果蝇神经仿真”关联了 goodbuddy“本地果蝇神经仿真”与微信 ClawBot“果蝇神经开源项目调研”（16 个事件），另有“Agent 实例生命周期与回收”关联 goodbuddy 与 dgx（24 个事件）。两次运行都无事件有两个主故事、无主故事跨项目、无小功能子线索，再次归属 0 次调用。
+- 未改善或变差：暂不归类增多（关闭 41→65，开启 30→49），模型在功能变宽后把更多零散事件留空，未逐条核对是否合理。首轮的 dgx＋阿里云跨项目故事这次未出现。子线索大多在归属调用中直接建出（关闭 18、开启 20 个事件由拆分调用移入子线索），拆分调用每次运行只触发 1 次。关闭、开启各只成功跑了一次，多次运行的切分是否一致未比较。
+- 单元测试：`supervision-stories.test.ts` 新增 3 项（版本名功能合并且不误结束、拆分调用的触发上限与用户事件保护及整块拒绝、跨项目功能列表与 `links` 关联及关闭时拒绝），共 9 项；与 `supervision-timeline.test.ts` 合计 13 项通过；Node 类型检查与相关 ESLint 通过。
+- 失败：另有两次运行中途失败、未完成。一次是开启跨项目时模型把“已结束”标记引用到未归入该故事的事件，整块被拒，导致整次归属失败（已在提示词中强调证据事件须归入同一故事，之后的开启运行通过）；一次是上述 `new_1_t1` 键格式，已放宽校验并加单元测试，但放宽后未再用真实模型重跑。严格校验下单块被拒会让整次归属失败，仍需重试才能补上。
+
+## 2026-10-02 故事线模型第 1 步：共享时间线
+
+对应[故事线模型改造设计](./storyline-model-design.md) SL-6、SL-7 和第 1 步。
+
+实现：
+
+- 处理进度改为一条共享时间线：`review_checkpoints` 的监督阶段只用 `scope = 'timeline'`，项目、全局和多项目组合共用。同一来源版本在任一范围成功发布后，其他范围不再提取；范围只决定读取和展示哪些来源。旧的按范围进度在升级时合并，不重读已处理内容。
+- 事件新增 `started_at`、`ended_at`、`project_id`、`superseded_by`，来源新增 `source_key`、`source_revision`（`supervision-timeline.ts`）。起止时间和所属项目按事件引用的来源记录计算，不由模型给出；来源跨多个项目时 `project_id` 为空。同一来源版本的重叠区间被后来的结果重新提取时，旧结果中的事件标记为已被替代，图谱和 MCP 只读当前事件，历史结果快照不变。
+- 图谱按范围读取共享时间线上的当前事件、实体、关系和来源，并返回 `attention`：按小时统计的消息轮次与正文量，只表示投入集中程度。
+- 新增设置“跨项目关联”（`supervisionReview.crossProject`，默认关闭）。关闭时，每批只把本项目已有的实体作为候选，不同项目的内容不会合并为同一实体；开启后候选来自全部项目。运行开始时冻结到本次配置。
+- Story Graph MCP：全局范围可以读到各项目的当前事件；来源可从运行范围、全局或包含该来源项目的项目范围读取。
+- Schema 53。
+
+验证：
+
+- 新增 `supervision-timeline.test.ts`：项目回顾后全局只提取其他项目的来源，相同项目再次回顾不调用模型；起止时间和项目来自来源；重新整理与项目回顾重叠后当前事件不重复；跨项目开关决定候选；Schema 52 升级合并进度和重复事件。`src/main/assistant` 全目录 28 个文件 324 项、Story Graph MCP 集成、监督相关 IPC 15 项、设置组件均通过。Node/Web 类型检查、相关 ESLint、`git diff --check` 通过。未运行全量测试。
+- 真实数据（`scripts/timeline-deepseek.mjs`，用 SQLite 在线备份复制本机 2.2 GB 数据库，原库只读）：升级 2.0 秒，`integrity_check` 为 ok。原有 423 个事件全部得到起止时间与项目；13 个两次回顾重复提取的事件被标记替代，当前 410 个（goodbuddy 358、默认项目 28、dgx 17、微信 ClawBot 5、阿里云-国内 2）；全局图谱返回 67 个小时段、790 轮对话的密度。
+- 真实模型（DeepSeek，`deepseek-flash`）：对 goodbuddy 最近 2 小时的 37 个来源做项目回顾，4 个批次加 3 次导航汇总，共 7 次请求，新增 27 个事件，起止时间都在区间内，未关联到其他项目的实体；再次项目回顾和同区间全局回顾均为无变化，0 次请求，全局重新提取的项目来源为 0。
+
+边界：
+
+- 这个 2 小时区间没有其他项目的消息，所以“全局只补其他项目”只在合成测试中验证过。
+- 模型通常让一个事件只引用一条消息，所以真实数据里的事件起止时间多数是同一时刻。按故事计算跨度要等第 2 步的故事归属。
+- 测试脚本把单次输出上限设为 8,192 token 时，一个批次的输出被截断，导致 JSON 无效。上限调到 32,768 后通过。产品路径不设这个参数，具体由 Runtime 的提供商配置决定。

+# 故事线模型改造设计
+
+状态：2026-10-02 已确认的目标设计。第 1 步（共享时间线、事件起止与密度、跨项目开关）、第 2 步（故事归属与用户调整）、第 3 步（时间螺旋视图）、第 4 步（经验抽取）和第 5 步（心跳故事建议、MCP 故事与经验查询、工作回顾按故事组织）已实现，见[实施进度](./progress.md)。本文定义监督回顾如何产出下一版故事线（时间螺旋、分层故事木片、经验 W），是 [3D 故事线图谱概念](../story-graph/3d-concept.md) 的数据来源合同。现有回顾流程见[回顾分块调度设计](./review-scheduling-design.md)，现有图谱工具见 [Story Graph MCP 设计](./story-graph-mcp-design.md)。
+
+## 1. 结构总览
+
+| 层 | 含义 | 来源 |
+| --- | --- | --- |
+| 全局（根） | 整条时间螺旋本身，即用户的全部经历；不是一片木片 | 所有来源 |
+| 项目木片 | 按会话所属项目划分；无项目归属的内容进入“未归属项目” | 会话归属，确定性，不调用模型 |
+| 跨项目故事 | 同时涉及多个项目或不属于任何项目的长期事情，例如长期偏好、学习方向 | 故事归属阶段 |
+| 功能木片 | 项目内的长期功能或主题 | 故事归属阶段 |
+| 子线索 | 事件量足够大的功能再拆分；小功能不拆 | 故事归属阶段 |
+| 经验 W | 从故事中形成、可复用到其他故事的经验，默认是全局对象 | 经验抽取阶段 |
+
+全局不作为单独的“全局记忆”重复处理：它是根视图，读取同一套事件、故事和经验。查看某个项目时，只是以该项目为过滤条件。
+
+## 2. 已确认的决定
+
+| 编号 | 决定 |
+| --- | --- |
+| SL-1 | 层级为 全局 › 项目 › 功能 › 子线索；子线索仅在功能事件量达到阈值时出现，阈值可在设置中调整 |
+| SL-2 | 跨项目或无项目的长期事情，作为全局根下的“跨项目故事”，与项目木片并列 |
+| SL-3 | 每个事件只归属一个主故事，可另外关联其他故事；关联不影响木片的长度和密度统计 |
+| SL-4 | 经验自动生成即可供 Agent 读取，不设确认门槛；标记“自动归纳”，用户可以编辑、合并、删除 |
+| SL-5 | 用户对故事和经验的调整（改名、合并、拆分、移动事件、编辑、删除）受保护，后续回顾不覆盖；删除的对象不会因同一证据再次生成 |
+| SL-6 | 注意力密度按来源统计：时段内的消息轮次与正文量，不由模型判断；只表示投入集中程度 |
+| SL-7 | 每个来源版本只提取一次，项目与全局共用提取结果和增量进度 |
+| SL-8 | 设置提供“跨项目关联”，默认关闭。关闭时新内容只关联本项目已有的知识；开启后可关联其他项目中的同一件事，跨项目故事也只在开启时生成 |
+
+## 3. 回顾流程改造
+
+```text
+采集来源（按来源版本增量）
+  ↓
+批次提取：事件带开始/结束时间（取原始消息时间）、来源引用
+  ↓
+故事归属（新增，不读原文）
+  · 项目：按会话归属确定
+  · 功能/子线索/跨项目：召回候选故事 → 一次模型调用判断归入已有、新建或暂不归类
+  ↓
+经验抽取（新增，低频，不读原文）
+  · 规则挑候选：有明确结果的决定、多个故事中重复出现的做法、说明原做法问题的修订
+  · 有候选时一次模型调用：经验内容、形成依据、适用条件、边界
+  · 记录后续应用及结果
+  ↓
+导航摘要 → 发布
+```
+
+规则：
+
+- 故事跨回顾保持同一身份，沿用实体候选编号机制；长时间无事件的故事能被接回，不新建。
+- 故事状态（进行中、已结束）必须有内容依据；长期无事件只标“暂无进展”，不推断结束。
+- 允许“暂不归类”，不为凑层级强行归组；暂不归类的事件在项目下以淡色木片显示。
+- 经验的每条依据必须对应到具体事件和来源，否则不保存；没有候选时不调用模型。
+- 新增阶段失败时，已发布的提取结果和处理进度保留，可单独重试该阶段。
+
+## 4. 用户调整
+
+图谱是可编辑的结果，不需要逐条审批：
+
+- 故事：改名、合并、拆分、调整层级、把事件移到其他故事。
+- 经验：编辑内容与适用条件、合并重复、删除。
+- 入口位于故事线图谱的详情面板与 3D 视图选中对象的详情中，共用同一组操作。
+- 每次调整可撤销，并记录在活动记录的修改记录中。
+
+## 5. 展示与使用
+
+- 故事线图谱新增 3D 视图，与现有平铺视图并列，几何、时间尺度、聚合规则沿用 [3D 概念](../story-graph/3d-concept.md)；Three.js 仅在打开 3D 视图时加载，WebGL 不可用时使用平铺视图。
+- MCP 增加按故事、按经验查询；经验返回时附“自动归纳 / 用户编辑”标记和依据。
+- 心跳建议增加“故事长期无进展”和“已有经验可能适用于当前故事”。两者都由规则选出：前者按设置的天数判断，只提示不改状态；后者要求共享不过于通用的实体。每次心跳各最多 3 条，排在未决事项之前。
+- 工作回顾按故事组织：推进了哪些故事、新出现哪些故事、形成或应用了哪些经验。
+
+## 6. 存储
+
+新增故事表（含层级与父故事）、事件与故事的归属/关联、经验表、经验依据与应用记录、用户调整记录；对应一次数据库升级。已有回顾结果在升级后按新流程重建，原始来源不变。
+
+## 7. 实施顺序与验收
+
+| 步骤 | 内容 | 验收（真实数据副本 + `.env.deepseek.local` 中的 DeepSeek） |
+| --- | --- | --- |
+| 1 | 统一时间线（SL-7）、事件时间跨度与密度（SL-6） | 重叠回顾不产生重复事件；项目与全局不重复处理同一来源 |
+| 2 | 故事归属与用户调整（SL-1～SL-3、SL-5） | 多次增量回顾后故事不碎片化；间断后的事件接回原故事；调整不被覆盖 |
+| 3 | 3D 视图接入真实数据 | 长期数据下时间尺度与聚合正常 |
+| 4 | 经验抽取（SL-4） | 每条经验依据可追溯到原文；无候选时零额外调用 |
+| 5 | MCP、心跳建议、工作回顾页 | Agent 能按故事接手工作、按经验给出建议 |

+Validation: 143 workspace and list-window tests passed, along with the real
+Electron layout test covering native resizing, drawer geometry, Escape focus
+return and note switching. Typecheck and lint on changed code passed. Repository
+lint was blocked by concurrent App.tsx changes (max-lines error and a missing
+conversationStore hook dependency warning). No provider calls were made.

+状态：已讨论的视觉方向，尚未实现。本文记录空间表达及概念图引用，不替代当前产品需求或技术设计。
+
+## 时间、事件与故事
+
+内部只有一条共同的时间螺旋。时间均匀推进，同一圈中交错发生不同事情；同一件事也可以在多个圈中间隔出现。
+
+每圈的时长随查看范围变化，使螺旋保持约 8 圈、最多 14 圈：一天约 3 小时一圈，一周 1 天一圈，一个季度 1 个月一圈，几年 1 季度或 1 年一圈。用户可以手动指定，指定值会超过 14 圈时改用更粗的粒度。注意力密度按当前粒度重新统计，每圈 8 个时段。
+
+同一故事中屏幕上过于接近的事件合并为一段，显示事件数量。点击聚合段，查看范围缩小到这段时间，事件随之拆开；小于约 6 小时仍无法拆开的事件（同一时刻多次提取），改为在右侧列出。
+
+[3D 网页 Demo](3d-demo.html) 已按上述几何规则和时间尺度实现，数据为本机故事线图谱的只读导出。
+
+螺旋半径可以随时间、随事件片段变化，表达注意力处理密度。时间轴不能随半径拉伸。密度的统计口径、归一化和缺失数据表现尚待定义，半径不代表效率、价值或成果。
+
+外层以木桶木片般的曲面连接同一故事的事件。木片起止时间、长度各不相同，可以顺着事件位置弯曲；不能为保持规则桶形而强行等长、等径。多年持续的故事可能只有少数活跃阶段，事件之间保留空白，连接只表达同一故事的延续。未结束的故事使用开放末端，不虚构未来事件。
+
+数据来源与层级（全局 › 项目 › 功能 › 子线索、跨项目故事、经验）由[故事线模型改造设计](../conversation-supervision/storyline-model-design.md)定义。
+
+Demo 底部的“跨项目故事”开关默认关闭。打开后，根层在项目木片旁增加跨项目故事木片（示例：果蝇神经仿真、Agent 运行环境、国内服务器部署），由多个项目中的功能组成；事件仍归属原项目，跨项目木片只做关联。关闭时只显示同一项目内的经验连接。示例中的跨项目分组按功能名称手工对应，产品中应由故事归属阶段提出，并允许用户调整。

+| K | 木片串联的故事及其形成的认识 |

+### 从故事中整理经验，保留适用条件和依据
+
+故事积累到一定规模，并出现新的决定、变化或里程碑后，监督者可以从事件摘要中归纳经验，保存适用条件、边界和形成依据。自动归纳的内容有明确标记，用户可以编辑、合并或删除，再回到原讨论核对。
+

 ### 助手可以查阅故事图谱，接着已有决定继续工作

+# 桌面端性能改造（第一期，参照 VS Code 架构）结项报告
+
+- **时间：** 2026-10-02 至 2026-10-04
+- **范围：** Desktop 的 Electron Main、Preload、Renderer 及其后台线程。远程主机（Agent、SSH、远程 Runtime）的稳定性和性能不在本期范围，下一期单独审查。
+- **结论：** 本期计划内的工作已完成。用户日常能感受到的卡顿（打字、流式输出、切换会话、滚动、启动、写库）都已测量并修复。剩下的工作是架构上的长期项（存储接口异步化、独立数据进程），风险高，已经写明理由，留到后续单独立项。
+- **相关文档：**
+  - 性能原则和评审清单：`docs/architecture/performance-principles.md`
+  - 逐项测量记录：`docs/roadmap/product-performance-experience-improvement-plan.md` 第 7 节（PERF-11 至 PERF-17）
+
+## 1. 结果
+
+### 1.1 模拟低端机（Renderer CPU 降速 4 倍）
+
+| 场景 | 改造前 | 改造后 |
+| --- | --- | --- |
+| 有 300 个会话时打字，按键延迟 p95 | 最高 4 秒 | 约 10–35 ms |
+| 流式输出时打字，按键延迟 p95 | 最高 9.6 秒 | 约 30–60 ms |
+| 流式输出期间卡住界面的总时长 | 16–21 秒 | 约 0.3–3 秒 |
+| 切回刚看过的会话，点击延迟 p95 | 约 530 ms | 约 110–140 ms |
+| 打开 2,000 条消息的会话 | 约 1.1–1.8 秒 | 约 0.27 秒 |
+
+### 1.2 标准机
+- `npm run perf:check` 的 60 项阈值全部通过。
+- 流式输出、流式输出时打字，超过 50 ms 的长任务均为 0。
+- 改造前，流式输出 40 KB 回答时约 47% 掉帧，帧间隔 p95 83 ms。
+
+### 1.3 Main 进程
+Main 卡顿的数据来自真实数据，以及 5 万个文本块的知识库。
+
+| 场景 | 改造前 | 改造后 |
+| --- | --- | --- |
+| 5 万个文本块的知识库混合检索 | 490 ms | 19 ms（移到只读 worker） |
+| 读取会话列表 | 25 ms | 0.8 ms |
+| 活动记录：启动读取 | 14.2 MB，198 ms | 114 KB，0.6 ms |
+| 活动记录：保存一条变化 | 114 ms | 6.9 ms |
+| 导入大 PDF | 0.5–0.7 s | 约 16 ms（移到解析 worker） |
+| 单次写库（真实数据） | 2.2–2.6 ms | 0.1–0.3 ms |
+| 写入期间偶发卡顿（真实数据） | 最长 346 ms，超过 50 ms 共 37 次 | 最长 34 ms，0 次 |
+
+### 1.4 启动
+真实数据：2.4 GB 数据库，175 万条任务事件。
+
+| 指标 | 改造前 | 改造后 |
+| --- | --- | --- |
+| 启动到输入框可用 | 3.70 s | 1.36 s |
+| 侧栏出现会话 | 4.08 s | 1.75 s |
+| 启动期间 Main 最长阻塞 | 2.5–2.8 s | 约 0.25 s |
+| 空配置启动 | 1,044 ms | 962 ms |
+
+## 2. 做了什么
+
+按性能原则 P1–P10 归类，提交号见计划文档。
+
+| 原则 | 改动 |
+| --- | --- |
+| P1 Main 只做调度 | 知识检索、Story Graph、会话列表、会话搜索、活动记录分页和汇总放到只读 worker；文档解析、分块、哈希放到解析 worker；WAL checkpoint 放到后台线程；远程事件按检查点批量写库；高频本地写入使用 `synchronous = NORMAL`；启动恢复改为按索引读取（schema 58） |
+| P2 状态局部订阅 | 流式缓冲、输入草稿、会话、任务和产物、活动记录、弹出层都改为独立 store；拆出 Composer、侧栏和隐藏路由并加 memo；切换会话只渲染一遍；`App.tsx` 从 11,246 行降到约 7,900 行，lint 设了上限 |
+| P3 高频数据按帧合并 | 流式文本按帧合并；终端输出在 Main 端按 8 ms 合并，界面每帧最多写一次；自动滚动每帧最多一次 |
+| P4 只传变化部分 | 活动记录改为增量保存和分页，统计由 Main 汇总，覆盖全部记录；Markdown 只重新解析变化的段落，并缓存解析结果 |
+| P5 工作量和可见内容成正比 | 消息时间线、会话侧栏、笔记、文件树、知识库文档表格都只渲染可见部分 |
+| P6 启动只做首屏需要的工作 | 本地工具环境改为后台初始化；Canvas、终端、SSH、OpenCode SDK 等模块改为用到时再加载；启动恢复改为按索引读取 |
+| P7 先测量，再修改 | 新增 `perf:app`（支持模拟低端机、内存、CPU 剖析）、`perf:main`、`perf:knowledge`、`perf:document-parse`、`perf:startup`（含 `real` 真实数据变体）、`perf:write`（真实数据回放） |
+| P8 正确性优先于速度 | 分段渲染与整篇渲染对照测试，含随机语料；活动记录与改造前的整份列表逻辑逐步对照；数据库写入顺序和持久性边界有专门测试 |
+| P9 用工具守住规则 | lint 规则：主进程禁止同步文件 API、限制 `DatabaseSync` 的使用范围、组件不得直接订阅 IPC、`App.tsx` 行数上限；`perf:check` 阈值 |
+| P10 体验不倒退 | 修复了 8 处体验倒退：回到底部的平滑动画、滚出可见区后丢失状态、跨消息选择文本、侧栏插入时跳动、终端回显、远程流式输出一顿一顿、复制时缺内容、锚定冲突 |
+
+## 3. 有意不做的部分
+
+| 项目 | 理由 |
+| --- | --- |
+| 存储接口全部异步化，新增独立数据进程（PERF-15、16 的剩余部分） | 约 500 处同步调用，并且要保证“先写后读”的顺序，风险高。最重的读已经移出 Main，写入已降到每次 0.1–0.3 ms，收益已经不大 |
+| Markdown 解析放到后台线程 | 需要重写渲染流程。标准机上流式输出已经不卡，只有低端机上的长回答还有余量 |
+| 窗口提前加载，接口请求排队等待 | 可省 200–300 ms，但要改动所有接口的注册顺序和首次运行流程 |
+| 会话队列移出 App | 和发送、恢���、中断联系太紧，拆出来的风险大于收益 |
+| 性能阈值接入 CI | 仓库目前没有 CI 配置 |
+
+## 4. 已知问题和下一步
+
+### 4.1 本期遗留
+- **打开最大的会话要等约 170 ms。** 这个会话有 407 条消息、42 MB 附加数据。读取在 worker 上，不卡界面，但切换时要等。根因是附加数据冗余：
+  - 子任务过程记录约 207 MB，主要是 `read`、`bash` 等工具的完整输出；
+  - 旧的 `tools` 和新的 `blocks` 重复保存，约 65 MB；
+  - 旧数据里有约 4 MB 内嵌图片。
+
+  建议去重，并把工具输出改为按需加载，单独立项。
+- **持久性的变化。** 高频本地写入改为 `synchronous = NORMAL`：断电时最多丢失最近一段运行事件和会话保存，应用崩溃时不丢。远程事件、通道投递、任务状态仍然每次落盘。
+- **没有在真实低配 Windows 机器上测过**，也没有用同一标准实测 VS Code 作为对照。
+- **全量测试中 2 个监督者相关测试失败**，在本期之前就已失败，属于另一项正在进行的工作。
+
+### 4.2 远程主机（下一期）
+本期涉及远程路径的改动只有 3 处：
+- `d859cbf`：远程事件按检查点批量写库；
+- `805acc3`：远程流式合并间隔从 50 ms 改为 16 ms；
+- `0dd4d1d`：远程事件仍然每次落盘，未降级。
+
+用户报告的 `Agent refused the stable controller generation resume` 和 `Runtime stopped before the prompt reached a terminal state` 两个错误，还需要在下一期确认和这些改动有没有关系。确认方式：在改动前后的版本上复现，对照远程事件写入和确认（ACK）的顺序。

+和 `hybridSearchWithDiagnostics`（图谱关闭）。这些调用是同步的，在 App 中由 Main 线程直接

+- **全量回写：** 活动记录在任何变化后 250 ms 全量 `replace`；会话每 500 ms 定时保存；
+  `*Changed` 通知不带内容，Renderer 再重新查询完整列表。
+
+改造完成后须同时满足以下规则，并由工具守护，避免回退：
+
+1. Main 只负责窗口、生命周期、权限和消息路由，不执行数据库查询、文档解析或批量计算。
+2. Renderer 状态按领域拆成外部 store，组件通过 selector 订阅；`App.tsx` 只保留布局壳。
+3. 流式文本和终端输出走专用通道，只更新正在显示的行或面板，按帧合并提交。
+4. 数据只有一个权威来源，跨进程只传增量；不再全量回写，也不再“通知后重新查全量”。
+5. 消息、会话、笔记、文件树等长列表虚拟化，DOM 数量不随数据量增长。
+
+实施方式：先建立 `PERF-11` 基线，再沿 Renderer（`PERF-12`→`PERF-13`→`PERF-14`）和
+数据进程（`PERF-15`→`PERF-16`）两条线并行推进，最后由 `PERF-17` 固化守护。每一步完成后
+重新运行 `PERF-11` 场景并记录对比；不换技术栈，不一次性重写 `App.tsx`。
+
+### PERF-11 完整 App 交互基准
+
+- **优先级 / 状态：** P1 / 进行中
+- **目标：** 在当前生产构建、隔离 profile 和本地假模型下，可重复测量用户能感知的卡顿。
+- **运行：** `npm run build:bundle` 后执行 `npm run perf:app`；结果写入
+  `GB_PERF_OUTPUT` 或系统临时目录，不含用户内容，不发出外部模型请求。
+- **场景：** 空闲基线；Composer 连续输入；切换会话；打开长会话；大量会话列表下的流式
+  回答；流式回答期间同时输入。
+- **指标：** Renderer Long Tasks（>50 ms）数量与总时长、按键到下一帧延迟、帧间隔 p95 与
+  掉帧比例、React commit 无法直接取得时以 DOM mutation 批次近似、Main event-loop 延迟
+  （`monitorEventLoopDelay`）、Main 与 Renderer 进程 CPU 和内存、Renderer JS heap。
+- **验收：** 同一设备多次运行结果可比较；报告记录源码版本、环境、数据规模和原始样本摘要。
+
+#### 实现
+
+- `build/run-app-perf.cjs`：独立 supervisor。在 `127.0.0.1:11434`（新 profile 默认模型地址）
+  启动 OpenAI 兼容假模型，清除 `ELECTRON_RUN_AS_NODE` 和模型环境变量，设置整轮期限（默认
+  600 s），汇总报告并删除隔离 profile。端口被占用时直接失败。
+- `tests/support/app-perf-driver.mjs`：在导入 `out/main/index.js` 前设置 `appPath`、
+  `userData`、`sessionData` 和日志目录，然后由生产 Main 创建窗口、注册 IPC 并加载真实
+  Preload/Renderer。全部交互使用 `sendInputEvent` 原生输入；数据通过生产
+  `conversations.saveLocal` IPC 写入，再 reload 走正常启动加载。
+- Renderer 探针只观察：`longtask`、`long-animation-frame`、Event Timing、rAF 帧间隔、
+  keydown 到下一帧、MutationObserver 计数、DOM 节点数和精确 JS heap。Main 用
+  `monitorEventLoopDelay`，进程用 `app.getAppMetrics()`。
+- 默认规模：300 个会话 × 20 条消息，另加一个 2,000 条消息的长会话；输入 120 个字符，
+  按键间隔 60 ms；流式回答约 40 KB 混合 Markdown（标题、列表、代码、表格、行内/块级公式、
+  引用），每个 SSE 事件 12 个字符，2,000 字符/秒。可用 `GB_PERF_*` 环境变量调整，
+  见脚本开头。
+- `GB_PERF_PROFILE=1` 为有历史输入和流式场景采集 Renderer CPU profile 并汇总自身耗时
+  热点；剖析有开销，只用于归因，不作为基线数据。
+- `GB_PERF_CPU_THROTTLE=<倍数>` 用 CDP 降低 Renderer CPU 速度模拟低端设备；
+  `GB_PERF_MEMORY_VISITS`（默认 24，0 跳过）控制 `PERF-09` 内存场景。
+
+#### 2026-10-02 基线
+
+源码 `8280158`（工作区含其他未提交改动），Windows x64，Intel Core Ultra X7 358H ×16，

+连续运行 3 次，假模型请求每次 2 次，外部模型请求 0 次。帧间隔基线为 8.3 ms（120 Hz）。
+
+| 场景 | Long Tasks 次数 / 总时长 | 帧间隔 p95 | 掉帧比例 | 交互延迟 p50 / p95 | Main lag 最大 |
+| --- | --- | --- | --- | --- | --- |

+
+其他观察：
+
+- 启动：窗口创建约 0.58 s，`ready-to-show` 约 1.29 s，Composer 可用约 1.42 s；带 300 个
+  会话 reload 到侧栏出现约 0.19 s。
+- 流式回答约 20 s，Long Tasks 占记录时间约 40%；按四等分统计为 `0 / 2.5 / 4.7 / 4.6 s`，
+  随回答变长而增加，说明每次提交的成本与已生成长度成正比。
+- 有历史时侧栏一次渲染全部 302 行，DOM 约 4,400 节点；访问过若干会话后约 1.6 万；两次
+  流式后约 4 万，JS heap 最高约 210 MB（keep-alive 缓存持续增长）。
+- 长会话只渲染最近 80 条，打开耗时主要是一次约 100 ms 的 Long Task。
+- KaTeX 的 `data:` 字体被 CSP 拒绝（缺少 `font-src`），每轮 8 条控制台错误，字体回退
+  （已在 `PERF-12` 第一步修复）。
+- `app.getAppMetrics()` 的 CPU 百分比在 Windows 上按全部逻辑核归一，只作相对比较。
+
+**归因（剖析运行）：** 流式期间 Renderer 自身 CPU 约 74% 在应用 bundle 中，热点是
+`hast-util-from-dom` 的 `parseFragment`/`fromDom`（rehype-katex 把 KaTeX HTML 再解析成
+hast）、micromark 分词、hast→React 转换和 React reconcile。对照实验确认根因：默认语料的
+块级公式写在一行（`$$...$$`），命中 `MarkdownRenderer.tsx` 的 `unsafeSegmentLine`，
+`splitMarkdownSegments` 退回整篇单段，**每次 flush 都重新解析整篇回答并重新渲染全部公式**。
+仅把 `$$` 改成独占一行（`GB_PERF_CORPUS=multiline-math`）后，同一流式场景 Long Tasks
+从约 130 次 / 9 s 降到 1 次 / 0.15 s，帧间隔 p95 从 83 ms 回到 8.5 ms，流式期间按键→帧
+p95 从约 36 ms 降到 15.5 ms。
+
+**结论与对后续批次的影响：**
+
+1. 当前最严重、用户最易感知的卡顿是**流式长回答**，且由 Markdown 分段失效后的整篇重解析
+   主导；输入、切换、滚动和空闲在本机均未出现明显问题。`PERF-12` 应优先处理：让分段在
+   单行 `$$`、HTML 行、链接定义等情况下也能安全工作或局部回退，并对已完成段缓存渲染结果。
+2. 假模型 2,000 字符/秒高于常见真实模型输出速度，但成本随长度线性增长，真实速度下回答
+   足够长时同样会出现。
+3. 会话首次切换 p95 约 100 ms、打开长会话约 140 ms，可在 `PERF-13`/`PERF-14` 中改善，
+   优先级低于第 1 项。
+4. 本机为高性能设备；低端设备上的绝对值会更差，后续应补一台低配 Windows 设备基线。
+
+### PERF-12 流式与输入快速止血
+
+- **优先级 / 状态：** P1 / 进行中（Markdown 分段已完成）
+- **范围：** 流式 delta 在 Renderer 按 `requestAnimationFrame` 合并后提交，并以 transition
+  降低优先级；缓存 Markdown 预处理结果；`RightAssistantSidebar`、`ProjectSwitcher` 和
+  keep-alive 路由使用 memo 并稳定回调；滚动跟随只在需要时执行。
+- **验收：** `PERF-11` 流式与输入场景的 Long Tasks 和输入延迟下降；事件顺序、停止、重试、
+  工具与 Subagent 块不回退。该项吸收 `PERF-04` 的范围。
+
+#### 2026-10-02 第一步：Markdown 分段与 KaTeX 字体
+
+- **分段（`MarkdownRenderer.tsx`）：** `splitMarkdownSegments` 按 micromark-extension-math
+  的实际规则识别块级公式：`$$` 等两个以上 `$` 开头、其后不含 `$` 的行才开启公式块，并需要
+  不短于开启长度的 `$` 行关闭；`$$x^2$$` 这类单行公式按普通段落处理，不再使整篇退回单段。
+  链接定义和脚注改为逐行检查，位于顶格代码围栏内的行视为字面内容。原始 HTML 行、`\r`、
+  缩进围栏内的定义仍整篇退回。
+- **字体（`electron.vite.config.ts`）：** Renderer 构建不再把字体内联为 `data:` URL。CSP
+  没有 `font-src`，原先 4 个小于 4 KB 的 KaTeX 字体被拒绝并回退；现在 60 个 KaTeX 字体
+  全部作为同源文件输出，CSP 不变。
+- **等价性验证：** 现有逐前缀对照语料新增单行公式、长 `$` 围栏、代码围栏内的定义等用例；
+  新增 1,200 份确定性随机文档（半数取随机前缀）对照，要求分段渲染与整篇渲染的 DOM 完全
+  一致。开发期另跑了约 4.8 万份随机文档与前缀，其中约 6,300 份走分段路径，全部一致。
+- **`npm run perf:app` 对比（同机，各 3 次，`80579ee` + 本改动）：**
+
+| 场景 | 改动前 | 改动后 |
+| --- | --- | --- |
+| 流式 40 KB：Long Tasks | 126–137 次 / 8.6–9.3 s | 1 次 / 0.16 s |
+| 流式 40 KB：帧间隔 p95 / 掉帧 | 83 ms / 45–48% | 8.6–8.9 ms / 3–5% |
+| 流式期间输入：按键→帧 p50 / p95 | 12.5–13.5 / 35–36 ms | 11.7–11.9 / 19–21 ms |
+| 流式期间输入：掉帧 | 50–52% | 7.7–8.5% |
+| KaTeX 字体 CSP 错误 | 每轮 8 条 | 0 |
+
+  输入、切换、长会话和滚动场景与基线持平。流式期间输入仍有约 8% 掉帧、按键 p95 约 20 ms，
+  剩余开销属于 App 级重渲染，留给 `PERF-12` 后续项和 `PERF-13`。
+- **剩余：** 流式 delta 按帧合并、大面板 memo、滚动跟随优化仍待实施。
+
+#### 2026-10-02 低端设备模拟（Renderer CPU 4× 降速）
+
+`GB_PERF_CPU_THROTTLE=4 npm run perf:app` 通过 CDP `Emulation.setCPUThrottlingRate` 把
+Renderer 主线程降速 4 倍（Main 不降速，每次 reload 后重新应用），源码 `5dc6545`
+（含 `PERF-12` 第一步），同一设备。不降速一栏为同一轮构建的对照。
+
+| 场景 | 不降速 | 4× 降速 |
+| --- | --- | --- |
+| 输入 120 字（新 profile）按键→帧 p95 | 8.7 ms | 42 ms，掉帧 21% |
+| **输入 120 字（有 300 个会话）** | 0 Long Task，p95 9 ms | **37 次 / 3.2 s，p95 355 ms，最大 483 ms** |
+| **首次切换会话 ×15** 点击→显示 p50 / p95 | 52 / 117 ms | **434 / 922 ms** |
+| 再次切换（缓存命中）p50 / p95 | 55 / 66 ms | 482 / 534 ms |
+| 打开 2,000 条消息会话 | 140 ms | 1.2 s |
+| 滚动长会话 | 帧 p95 8.5 ms | 帧 p95 17 ms，正常 |
+| **流式 40 KB** | 1 次 / 0.17 s，帧 p95 17 ms | **156 次 / 16.7 s，帧 p95 183 ms，掉帧 100%** |
+| **流式期间输入** 按键→帧 p50 / p95 | 11.5 / 17 ms | **575 / 1,513 ms** |
+
+高性能机上不可见的问题，在降速后全部暴露：
+
+- 新 profile 输入只到 42 ms，有 300 个会话后升到 355 ms，差异来自**每次按键重新渲染整个
+  App 和完整侧栏**。降速剖析：`resizeComposerTextarea`（每次输入同步读 `scrollHeight` 强制
+  布局）约 8%；i18next `formatLanguageCode`/`translate` 约 12%（`Intl.getCanonicalLocales`
+  每次调用 `t()` 都执行，侧栏 302 行各自多次调用）；其余是 App 与侧栏行的 React 渲染。
+- 流式期间约 18% 是 `ChatHistoryPane` 每次 flush 的滚动跟随 layout effect（读布局后
+  `scrollTo`），i18next 约 8%，Markdown 解析与 React reconcile 其余。
+- 缓存命中切换也约 0.5 s，说明慢的不是挂载新面板，而是切换触发的 App 级整体重渲染。
+
+**结论：** 低端设备上输入、切换和流式都会明显卡顿，主因是 App 级重渲染和侧栏全量渲染，
+证实 `PERF-13`（领域 store）和 `PERF-14`（侧栏虚拟化）有必要。`PERF-12` 剩余项应先做三处
+低成本热点：Composer 高度改为只在需要时测量、`t()` 结果或 i18next 语言码规范化做缓存、
+滚动跟随按帧合并且只在贴底时执行。
+
+#### 2026-10-02 第二步：三处低成本热点
+
+- **Composer 高度（`App.tsx` `resizeComposerTextarea`）：** 记住上次的值与高度。值未变不测量；
+  在原文本末尾追加时不再先设 `height: auto`（只会变高），已到最大高度直接跳过测量；删除、
+  替换、清空仍按原方式重置并测量。
+- **i18next 语言码（`i18n/index.ts`）：** i18next 25 每次 `t()` 都经
+  `toResolveHierarchy`→`formatLanguageCode` 调用 `Intl.getCanonicalLocales`。初始化后对
+  `languageUtils.formatLanguageCode` 加按输入缓存（结果只取决于代码与静态初始化选项，上限
+  64 项），翻译结果不变。
+- **滚动跟随（`ChatHistoryPane.tsx`）：** 激活面板时仍同步滚到底；之后内容更新时改为每帧最多
+  一次 `requestAnimationFrame` 中读取 `scrollHeight` 并 `scrollTo`，回调里再次确认仍贴底；
+  卸载时取消。读者离开底部时不滚动，恢复阅读位置逻辑不变。
+- **测试：** 新增“流式三次更新只滚动一帧”（旧实现 3 次，失败）、Composer 追加与删除的测量
+  次数、`t()` 不再调用 `Intl.getCanonicalLocales`。全量测试 5,621 通过，2 失败与本改动
+  无关（真实 OpenCode 集成测试因免费额度返回 403；Supervisor 超时设置用例此前已失败）。
+- **`npm run perf:app` A/B（同机，改动前为临时 worktree 中的 `983cdd4` 构建，交替运行）：**
+
+| 场景（4× 降速，3 轮） | 改动前 按键/点击 p50 / p95 | 改动后 |
+| --- | --- | --- |
+| 输入 120 字（新 profile） | 28–80 / 33–361 ms | 19–36 / 24–57 ms |
+| 输入 120 字（有 300 个会话） | 265–2,372 / 1,486–4,266 ms | 27–161 / 32–346 ms |
+| 首次切换会话 | 442–761 / 1,063–1,384 ms | 360–398 / 820–1,334 ms |
+| 再次切换（缓存命中） | 472–749 / 501–1,143 ms | 390–420 / 456–951 ms |
+| 流式 40 KB：Long Tasks 总时长 | 15.9–20.6 s | 15.1–17.4 s |
+| 流式期间输入 | 432–6,778 / 1,146–9,634 ms | 96–466 / 297–1,567 ms |
+
+  不降速时（2 轮）两版各场景持平，输入 p95 均约 9 ms，流式 1 个 Long Task。4× 降速下
+  方差很大（同版本轮间可差数倍），应看量级：有历史时输入从秒级回到百毫秒内，切换略有改善，
+  流式本身仍是每帧卡顿——剩余成本是 App 级重渲染与 Markdown/React 提交，需 `PERF-13`。
+- **剩余：** 流式 delta 按帧合并后以 transition 提交、大面板 memo 仍待实施；之后进入
+  `PERF-13`。
+
+### PERF-13 Renderer 领域 Store 迁移
+
+- **优先级 / 状态：** P1 / 进行中（流式缓冲、Composer 草稿已迁移）
+- **顺序：** 流式缓冲 → Composer 草稿 → 会话与消息 → 任务与通知 → 设置及其余界面状态。
+- **每个领域的完成步骤：** 建立 store 并把 IPC 订阅移入 store；调用方改为 selector；删除
+  App 中对应 state/ref 同步代码；运行测试与 `PERF-11`。
+- **验收：** 输入和流式更新不再重新渲染 App 根组件；`App.tsx` 最终降到布局壳规模。
+
+#### 2026-10-02 第一步：流式缓冲与 Composer 草稿
+
+- **流式缓冲（`live-message-store.ts`）：** `text`/`reasoning` delta 不再逐条 `setConversations`，
+  而是写入按消息分组的外部 store；`ChatMessageRow` 用 `useSyncExternalStore` 订阅自己的消息，
+  只有这一行重新渲染。App 状态每 250 ms 吸收一次，或在任何其他会话更新时先吸收。
+  - 每个 delta 带序号和应用后的正文/思考长度。store 生成的消息对象记录已包含的序号；持久化
+    快照等外来��象按长度判断（delta 只追加），因此不会重复或丢失。
+  - 一次更新只吸收派发时已到达的 delta，工具、审批等块与文本保持原有顺序。
+  - 吸收后裁剪已提交的 delta，行内显示增量折叠，长回答期间缓冲区保持很短。
+  - 吸收用普通更新而非 transition：transition 会被行的同步更新反复打断，导致缓冲区一直增长
+    （首版实测出现过流式 Long Tasks 翻倍）。
+- **Composer 草稿（`composer-draft-store.ts`）：** 按会话的草稿移出 App state；输入框和发送按钮
+  分别订阅草稿文本和“是否有内容”，按键不再重渲染 App。高度调整改为草稿提交后的 layout effect。
+- **测试：** store 单测覆盖折叠等价、提交前显示、工具块顺序、派发时快照、替换快照不重复、
+  React 重放幂等、无基线不隐藏、长流裁剪；App 测试改为断言流式文本不再渲染历史面板与任务条。
+- **`npm run perf:app` A/B（同机，改动前为临时 worktree 中的 `90ea33e` 构建，交替运行）：**
+
+| 场景（4× 降速，3 轮） | 改动前 p50 / p95 | 改动后 |
+| --- | --- | --- |
+| 输入 120 字（新 profile） | 18–21 / 24–26 ms，掉帧 7–13% | 9–10 / 11–16 ms，掉帧 0–1% |
+| 输入 120 字（有 300 个会话） | 27–81 / 35–227 ms | 10–19 / 12–36 ms |
+| 流式 40 KB：Long Tasks 总时长 | 6.5–20.8 s | 3.6–19.3 s（3 轮中 2 轮约 4–5 s） |
+| 流式期间输入 | 73–1,808 / 174–3,498 ms | 34–62 / 59–573 ms |
+| 打开 2,000 条消息会话（见下方更正） | 1.07–1.80 s，帧 p95 9–42 ms | 0.47–0.76 s，帧 p95 75–1,008 ms |
+| 首次 / 缓存命中切换会话 | 持平 | 持平 |
+
+  **更正（归因）：** “改动后”构建包含了当时工作区中另一项未提交的改动——新会话面板分两步
+  渲染（先最后 20 条，首帧后补齐 80 条，后提交为 `09c415b`）。打开长会话的耗时下降主要来自
+  它，而不是流式缓冲；同时补齐那一帧变成长帧，4× 降速下该场景帧间隔 p95 从 9–42 ms 升到
+  75–1,008 ms。输入与流式期间输入的改善来自本步骤。分两步渲染只是过渡，补齐帧的成本需由
+  `PERF-14` 虚拟化解决。
+
+  不降速时（2 轮）各场景持平或略好，流式期间输入 p95 从 15–17 ms 降到 11–12 ms。流式本身在
+  4× 降速下仍每帧掉帧：剩余成本是行内 Markdown 解析与 KaTeX 渲染，以及每 250 ms 一次的 App
+  级吸收；切换会话的 App 级重渲染未改善，留给后续领域迁移。
+- **远程 Runtime：** 远程事件与本地事件走同一 `agent:event` 通道和同一 Renderer 处理函数，
+  上述 Renderer 改进同样生效。远程事件在 Main 中逐条同步写 SQLite（每个 delta 约 2 个写事务，
+  会话恢复路径还会重写整条消息）后再转发，这部分未改，归入 `PERF-15`/`PERF-16`。
+- **基准工具：** `GB_PERF_MODEL_PORT` 可把假模型移到其他端口（例如本机已运行 GoodBuddy 占用
+  11434 时），隔离 profile 通过 `GOODBUDDY_MODEL_*` 环境变量指向它。
+
+#### 2026-10-02 其他改动的架构核对
+
+对同期其他功能改动按本批次 5 条规则核对（监督者功能除外）：
+
+- **一致：** 剪贴板改为异步读写（`d773f5e`）；未保存修改通过 context 上报、记录不进 App state，
+  有未保存修改的路由不被缓存淘汰（`43be465`）；新会话面板分两步渲染（`09c415b`，过渡方案）。
+- **偏离规则 1：** Story Graph 检索（`e97263c`）仍在 Main 内经 `DatabaseSync` 读取后，在 JS 中
+  逐条 `JSON.stringify` 并按多个关键词匹配，单次成本高于原整句匹配；工具描述又鼓励 Agent
+  主动调用，调用次数会增加。纳入 `PERF-15`/`PERF-16`，在此之前补测检索耗时并限制扫描规模。
+- **偏离规则 2：** 侧栏 5 秒重排（`ee4eb73`，`use-conversation-list-order.ts`）由 App 持有状态，
+  渲染期间 setState，定时器每 5 秒检查；顺序不变时跳过，当前成本低。交互上悬停、滚动、菜单
+  打开时不重排。侧栏迁移和虚拟化（`PERF-13`/`PERF-14`）时移入侧栏组件。
+- **React 规则：** 缓存会话保持滚动位置（`bf6c4a9`）在渲染期间写 ref，即当前 lint 的 3 条
+  `react-hooks/refs` 错误；启用 React Compiler 前需改为由状态派生顺序。
+
+#### 2026-10-02 并行修复：补全分帧、远程批量写库、架构守护
+
+- **补全分帧（`ChatHistoryPane.tsx`）：** 新面板补全改为每帧 +20 条（20→40→60→80），每步后
+  贴底或按高度差保持阅读位置；“加载更早”、批次变化或笔记跳转到达时立即渲染完整批次。
+- **渲染期 ref（`App.tsx`、`pane-order.ts`）：** 会话面板顺序改为 state，用纯函数
+  `reconcilePaneOrder` 在渲染期按需调整，顺序不变时返回原数组；消除 3 条 `react-hooks/refs`。
+- **远程批量写库（`remote-event-batcher.ts`、`assistant-database.ts`、`ipc.ts`）：** 远程语义事件
+  按 checkpoint 一个事务提交（Agent 在 checkpoint 之后才可能 ACK），可恢复会话每批只读写一次
+  消息；非远程事件、`question`、`done`/`error`、显式 flush、256 条或 50 ms 计时器也会先提交。
+  只转发新写入的事件，顺序不变；提交失败整批回滚且之后拒绝继续提交。交互、后台/定时/通道
+  和重启恢复三条路径都已改用。当前 checkpoint 粒度是每条 transcript 记录而非每页，按页批量
+  需要改 `acp-remote-runtime.ts`。
+- **架构守护（提前实施 `PERF-17` 的一部分）：** `eslint.config.js` 新增只减不增的白名单规则：
+  `DatabaseSync`（19 个文件）、`src/main` 同步 fs（8 个文件）、组件直接订阅
+  `window.goodbuddy.*.on*`（6 个文件）、`App.tsx` `max-lines` 11700；文档演示和 vendor 脚本
+  不再参与 lint，`npx eslint .` 现为 0 错误。`build/perf-thresholds.json` +
+  `npm run perf:check`（或 `GB_PERF_CHECK=1 npm run perf:app`）检查不降速报告的阈值。
+- **`npm run perf:app` A/B（改动前为 `9d8477b`）：** 不降速 2 轮两版均通过 60 项阈值；打开长会话
+  从 1 个 Long Task / 56–61 ms、最大帧 50–58 ms 降到 0 个、最大帧 25–33 ms，其余持平。4× 降速
+  3 轮：打开长会话最大帧从 475–567 ms 降到 225–283 ms（帧 p95 因多出几帧小提交升到
+  175–258 ms）；切换会话持平；流式场景两版方差都很大，未见一致变化。远程批量写库不在该基准
+  覆盖范围内，由单元测试和 `ipc.test.ts` 验证事务次数、顺序与回放去重。
+
+#### 2026-10-03 会话与消息领域（第一片）
+
+- **会话 store（`conversation-store.ts`、`conversation-selectors.ts`）：** 会话数组移出 App state，
+  `getState()` 同步可读，取代 `conversationsRef` 及其 5 处直接写入；`set()` 先吸收流式 delta
+  再同步更新。按会话 id 和列表两级通知，选择结果未变时保持同一对象。
+- **侧栏（`ConversationSidebar.tsx`）：** 搜索匹配、5 秒重排、行级派生值移入侧栏自身订阅；
+  切换会话时侧栏只重渲染状态翻转的两行。顺便修复 React 19.2 中 `memo` 组件内
+  `useEffectEvent` 不刷新导致重排用旧列表的问题（有回归测试）。
+- **App 只订阅：** 活动会话、缓存面板的会话、数量，以及标题/审批/项目活动的按值比较
+  选择器。`App.tsx` 从 11,636 行降到约 10,960 行。
+- **仍在 App：** 未读、展开、菜单、重命名、删除等界面 ID；持久化、历史加载与合并；
+  活动会话的更新（含 250 ms 流式吸收）仍重渲染 App。
+
+#### 2026-10-03 PERF-13 进展：Composer、路由边界、任务 store、切换会话
+
+提交 `41be9f8`、`2e3d2e7`、`651475d`、`492f1d2`、`6b634c5`。
+
+- **Composer（`Composer.tsx`，`memo`）：** 输入区页脚（约 930 行 JSX、23 个内联回调）移出 App。
+  草稿读 `composer-draft-store`，会话字段读 `useComposerConversationView`（不含消息数和结果 ID），
+  弹出菜单状态放进 `composer-menu-store.ts`；动作经 `use-composer-actions.ts` 保持同一引用。
+  其他会话更新、当前会话新增消息、别的会话输入都不重渲染 Composer（有测试）。
+- **路由边界：** `KeepAliveRoute` 改为 `memo`，隐藏路由在 App 重渲染时保持上次结果，再次显示时
+  补一次渲染。知识库、设置、监督、笔记、右侧栏、项目切换器改为 `memo`，知识库 26 个回调移到
+  `use-knowledge-workspace-actions.ts`，其余用 `useStableHandlers`；笔记面板元素 `useMemo`。
+- **任务与结果（`task-store.ts` / `task-selectors.ts` / `task-sync.ts`）：** `assistantTasks`、
+  `assistantArtifacts` 移出 App state，`assistantTasksRef` 删除。App 只选取顶层任务状态、活动摘要
+  所需字段和当前会话是否忙碌，子代理进度不再重渲染 App；结果刷新时内容相同的对象保留引用，
+  会话面板自己读结果表。`agent-event-handler.ts` 只改了任务/结果调用。队列状态未迁移：它和发送、
+  恢复、中断流程交织，单独拆风险高于收益。
+- **切换会话：** 面板顺序改为渲染期派生（`usePaneOrder`），Composer 弹窗按上下文键关闭，
+  不再在渲染中 setState，切换一次只渲染 App 一次（测试在旧代码上为 2 次）。标题表在标题不变时
+  保持同一 Map。
+- **规模：** `App.tsx` 9,576 → 7,904 行（含期间合入的监督者改动）；App 内 useState 120→114、
+  useEffect 62→56、useRef 79→73、useCallback 89→83。lint 上限 9,600 → 8,000。
+- **`npm run perf:app` A/B**（改动前为 `b28ddd4` 临时 worktree 构建，与 `6b634c5` 交替各 3 轮，
+  4× 降速，取中位数，括号为 3 轮范围）：
+
+| 场景 | 改动前 | 改动后 |
+| --- | --- | --- |
+| 首次切换会话 延迟 p95 | 525 ms（520–674） | 489 ms（470–607） |
+| 首次切换 Long Tasks 数 / 总时长 | 37 / 3.9 s | 24 / 2.0 s |
+| 缓存切换（warm）延迟 p95 | 254 ms（208–256） | 139 ms（135–149） |
+| 缓存切换 Long Tasks 数 / 总时长 | 21 / 1.7 s | 12 / 0.7 s |
+| 热切换（hot）延迟 p95 | 139 ms | 94 ms（77–154） |
+| 流式 40 KB：Long Tasks 数 / 总时长 / 帧 p95 | 90 / 7.0 s / 208 ms | 49 / 3.1 s / 108 ms |
+| 流式期间输入：延迟 p95 / Long Tasks 总时长 / 帧 p95 | 110 ms / 8.3 s / 233 ms | 53 ms / 3.5 s / 100 ms |
+| 输入（有 300 个会话）延迟 p95 | 11.7 ms | 14.1 ms（12.6–15.9，噪声范围内） |
+
+  流式两个场景的掉帧率仍接近 100%（4× 降速下每帧仍有 Markdown 解析和 250 ms 吸收），但 Long
+  Tasks 减半。不降速一轮 `GB_PERF_CHECK=1`：60 项阈值全部通过。
+
+### PERF-14 长列表虚拟化
+
+#### 2026-10-03 消息时间线窗口化
+
+- **实现（`chat-message-window.ts`、`ChatHistoryPane.tsx`、`ChatTimeline.tsx`）：** 自研窗口化，
+  未引入依赖。只挂载视口附近的行（上限 60 行，外加获得焦点的行），其余用按实测高度或
+  平均高度估算的占位块代替；行高按会话缓存（最多 24 个会话）。以视口内的一行为锚点，
+  行高变化或挂载/卸载时修正滚动位置，读者看到的内容不动。
+- **保留：** 96 px 贴底阈值和流式时每帧跟随；发送消息回到底部；“加载更早”仍按 80 条扩展
+  可滚动范围；笔记跳转先挂载目标再滚动；隐藏/显示和重新挂载恢复位置；隐藏面板不测量。
+  分帧补全（`09c415b`/`855b941`）已删除，打开面板一次提交有界行数。
+- **滚动滞后窗口：** 视口离开已挂载范围 160 px 内才重新取窗，取窗时挂载 1.5 屏余量，避免
+  每个滚动事件都重挂行。
+- **毛玻璃锚点：** 锚点以 `.chat-content` 的上内边距为基准，切换毛玻璃时阅读位置不变
+  （由 `tests/frosted-glass.electron.test.ts` 在真实 Electron 中验证，该测试改为按消息 id 跟踪
+  锚点行）。
+- **已知限制：** 页内查找搜不到未挂载的消息；快速甩动时可能短暂看到空白占位；单条超长
+  消息仍整行挂载；估算高度会让滚动条滑块在首次经过时轻微变化。
+
+### PERF-15/16 第一片：热点读路径移出 Main
+
+#### 2026-10-03 只读查询 worker
+
+- **实现（`readonly-query-reader.ts`、`readonly-query-worker.ts`）：** 每个数据库文件一个只读
+  worker 线程，沿用 `execution-stats-reader` 的模式，复用 `KnowledgeDatabase` /
+  `AssistantDatabase` 的生产方法，结果与同步路径同源。最多 32 个并发请求；worker 崩溃或
+  启动失败时转为同步执行，30 秒后再重启；`:memory:` 始终同步。`AbortSignal` 通过共享标志
+  取消（向量扫描每 256 行检查）。没有新增 `DatabaseSync` 白名单。
+- **已移出 Main：** 知识库检索（`retrieve`、`searchHybrid`）；Story Graph 读取（Agent 通过 MCP
+  调用，先在 SQL 中按范围预筛，超过 5 万个对象返回 `scan_limit_exceeded`）；会话搜索（一条
+  SQL + 注册函数，保持 `toLocaleLowerCase().includes()` 语义）。会话列表的 N+1 查询改为两次
+  批量查询，IPC 结构不变。
+- **`npm run perf:knowledge`（改用 Electron 运行）：**
+
+| 文本块 | 混合检索时 Main 最大事件循环延迟（同步 → worker） | 单次耗时（同步 / worker） |
+| --- | --- | --- |
+| 5,000 | 54.9 → 19.5 ms | 47.7 / 53.3 ms |
+| 20,000 | 204.3 → 19.6 ms | 188.6 / 198.9 ms |
+| 50,000 | 489.9 → 18.6 ms | 466.8 / 478.6 ms |
+
+- **剩余：** 向量检索仍是全表扫描（只是不在 Main 上）；写入和其余约 530 处同步调用仍在
+  Main；独立数据进程和 `DatabaseSync` 白名单缩减未开始。
+
+#### 2026-10-03 三项合并后的 `npm run perf:app` A/B（改动前为 `53b9ecb`）
+
+不降速：新版本通过全部 60 项阈值。4× 降速（改动前 3 轮，改动后 3 轮，滚动场景另取调整后
+2 轮）：
+
+| 场景 | 改动前 | 改动后 |
+| --- | --- | --- |
+| 首次切换会话 p50 / p95 | 335–377 / 677–730 ms | 198–312 / 518–634 ms |
+| 切回刚看过的会话 p95 | 379–386 ms | 179–240 ms |
+| 切回最近的会话 p95 | 161–164 ms | 89–140 ms |
+| 打开 2,000 条消息会话 | 448–484 ms，帧 p95 200–225 ms | 290–354 ms，帧 p95 8–9 ms |
+| 滚动长会话：帧 p95 / 掉帧 | 17 ms / 7% | 58–67 ms / 15–16% |
+| 流式输出、流式时打字 | 两版波动都很大，未见一致变化 | 同左 |
+| 打字、空闲 | 持平 | 持平 |
+
+滚动是唯一变差的场景：改动前长会话一次性挂载所有已加载行，滚动只是移动画面；窗口化后
+每隔几屏要挂载新行（含 Markdown 渲染）并测量。初版每个滚动事件都重新取窗，掉帧约 70%；
+加入滞后窗口后降到 15–16%。剩余开销主要在新行渲染和 `getBoundingClientRect` 测量，后续
+可把锚点测量合并到每帧一次，或给 Markdown 结果加缓存。
+
+#### 2026-10-03 第二轮并行：滚动、Markdown 缓存、侧栏窗口化、App 继续瘦身、活动记录
+
+- **滚动（`ChatHistoryPane.tsx`、`chat-message-window.ts`）：** 滚动事件只读 `scrollTop` 等
+  滚动容器指标；是否重新取窗改为每帧最多判断一次，并用“锚点行 + 缓存行高”推算视口位置，
+  稳定滚动时不读元素几何。提交后只有挂载集合或占位高度变化时才校正锚点；上内边距缓存，
+  在 resize、激活和重新取锚点时刷新（真实 Electron 毛玻璃测试曾因缓存旧边距偏 105 px，已修）。
+- **Markdown 渲染缓存（`markdown-render-cache.ts`）：** 按源文本和管线配置缓存解析后的 hast
+  树（LRU），重新挂载的行跳过 micromark/remark/rehype/KaTeX，只做 hast → React。
+- **侧栏窗口化（`use-conversation-list-window.ts`）：** 60 个会话以上只挂载视口附近的行，
+  活动会话、菜单、重命名、获得焦点的行保持挂载；`aria-setsize`/`aria-posinset` 保留总数。
+- **App 继续瘦身：** 会话持久化与历史加载（`conversation-persistence.ts`）、刷新调度
+  （`conversation-refresh.ts`）、Agent 事件处理（`agent-event-handler.ts`）、历史面板
+  （`ConversationHistorySlot.tsx`）移出 App。`App.tsx` 从约 10,960 行降到 9,566 行，lint 上限
+  改为 9,600。
+- **活动记录（`activity-history-plan.ts`）：** Main 的整份替换只校验、序列化变化的记录；
+  新增增量 IPC `activity-history:update`。Renderer 还没有改用增量接口。
+- **会话读取：** `conversations:list-summaries` 和 `conversations:get` 也改由只读 worker 执行。
+- **`npm run perf:app` 驱动：** 侧栏窗口化后不再一次挂载全部会话，驱动改为按 `aria-setsize`
+  判断加载完成，点击会话前逐屏滚动侧栏直到该行挂载。
+
+`npm run perf:main`（1,000 个会话 / 2 万条消息 / 5,000 条活动记录，Main 事件循环最大延迟）：
+
+| 路径 | 改动前 | 改动后 |
+| --- | --- | --- |
+| 会话摘要列表 | 25.4 ms | 0.8 ms（单次耗时 31 ms，在 worker 上） |
+| 活动记录整份替换，无变化 | 13.8 ms | 9.3 ms |
+| 活动记录增量更新 1 条 | — | 5.3 ms |
+
+`npm run perf:app`，4× 降速，改动前（`169941c`）与改动后各 3 轮：
+
+| 场景 | 改动前 | 改动后 |
+| --- | --- | --- |
+| 滚动长会话：帧 p95 / 掉帧 | 25–50 ms / 10–11% | 17–41 ms / 9–10% |
+| 打开 2,000 条消息会话：长任务 / 点击 p95 | 165–170 / 238–247 ms | 97–105 / 211–218 ms |
+| 首次切换会话：长任务 / 点击 p95 | 1,969–2,115 / 444–460 ms | 1,256–1,341 / 425–435 ms |
+| 切回刚看过的会话：长任务 / 点击 p95 | 1,084–1,183 / 151–158 ms | 152–205 / 110–146 ms |
+| 流式输出 40 KB：长任务总时长 / 掉帧 | 1.6–2.4 s / 90–99% | 0.33–0.41 s / 63–72% |
+| 流式时打字：长任务 / 按键 p95 | 3.0–3.6 s / 41–48 ms | 0.53–0.64 s / 29–43 ms |
+| 有历史时打字：DOM 节点 | 4,382 | 705–719 |
+
+不降速：全部阈值通过；流式输出和流式时打字的长任务均为 0。上一轮滚动的退化已消除（本轮基线
+已含窗口化，故与 `53b9ecb` 的 17 ms / 7% 不完全可比，帧 p95 在两版中都波动较大）。
+
+#### 2026-10-03 本期收尾：已做、暂缓与理由
+
+本期收尾只做低风险改动：
+
+- **侧栏 id 列表保持同一数组**（`ConversationSidebar.tsx`）：流式更新时，会话对象每次都会变，
+  原来每次都生成新的 id 数组，导致侧栏窗口化的布局 effect 重跑并读取 `scrollTop`。4× 降速剖析
+  显示，这段在流式场景中占 562 ms self time。现在 id 不变时，数组也保持不变。
+- **会话标题跑马灯不在挂载时强制布局**（`OverflowMarquee.tsx`）：挂载时不再同步读取
+  `scrollWidth`，改由 ResizeObserver 在首次报告时测量，有回归测试。悬停时的测量方式不变。
+- 4× 降速下复测，这两项的变化都在波动范围内（同版本多次运行，差距可达 2 倍），没有出现退化；
+  不降速时 60 项阈值全部通过。
+
+**本期暂缓，理由如下：**
+
+| 项目 | 理由 |
+| --- | --- |
+| Renderer 改用 `activity-history:update` | 需要在 App 中跟踪每次变化并处理顺序与失败重试；Main 端已经只处理变化的记录，Main 卡顿从 13.8 ms 降到 9.3 ms，剩余收益小，而出错会丢活动记录 |
+| 数据库写入异步化、独立数据进程（PERF-15/16 剩余部分） | 涉及约 530 处调用和写入顺序语义，属于高风险大改动；本期已把最重的读取路径（检索、会话列表、搜索）移出 Main，需要单独立项 |
+| 首次切换会话（4× 降速 p95 约 430 ms） | 剖析显示，开销分散在 React 渲染、首次 Markdown 解析和 i18n 上，没有单一热点；不降速时 p95 约 70 ms，已在阈值内 |
+| 流式输出 Markdown 放进 worker | 需要重写渲染管线，并处理流式中途结果和公式；不降速时流式场景已无长任务 |
+| 页内查找覆盖未挂载的消息 | 当前 App 没有页内查找功能（未调用 `findInPage`），属于新功能，不是回归 |
+| 性能阈值接入 CI | 仓库目前没有 CI 工作流；`npm run perf:check` 可以在本地运行 |
+
+### 7.2 按性能原则补齐差距（2026-10-03，第三轮并行）
+
+统一标准见 `docs/architecture/performance-principles.md`（P1–P10、性能预算和评审清单）。本轮按其中“当前差距”并行推进：
+
+| 原则 | 改动 | 测量结果 |
+| --- | --- | --- |
+| P1 | 文档解析、PPTX 提取、分块、大文件（≥ 1 MiB）哈希移到 `document-parse-worker` 线程，FIFO 队列；worker 不可用或崩溃时退回原来的 Main 内联执行，30 秒后重试；中止正在执行的任务会终止 worker。数据库写入仍由调用方按原顺序执行 | `npm run perf:document-parse`，各 3 轮：Main 最长阻塞 large.pdf 498–679 → 16–17 ms，large.docx 313–335 → 17–20 ms；总耗时基本不变 |
+| P3 | 终端输出：Main 端按 8 ms 窗口合并（空闲时第一块立即发出，不增加回显延迟），单批不超过 64 KiB；控制事件（退出、错误、状态）发出前先清空缓冲，顺序不变；背压按“已发出 + 已缓冲”字节计算，暂停阈值留 1/4 余量。Renderer 端每帧最多写一次 xterm，写完后按最大序号累计 ACK；窗口不可见时 100 ms 定时兜底，保证 ACK 不中断 | 单元测试覆盖顺序、UTF-8 边界、背压、退出前清空；`perf:app` 未覆盖终端场景 |
+| P5 | 笔记列表（按卡片行窗口化，CSS subgrid）、工作区文件树（展开后拍平，按缩进显示层级）、知识库文档表格只渲染可见部分；抽出通用 `use-list-window` / `use-grid-columns`，侧栏会话列表改用同一实现。选中项、打开菜单的行、焦点行保持挂载 | 每个列表新增窗口化单元测试；真实 Electron 文件树布局测试改为验证窗口化后的停靠、滚动和预览返回 |
+| P6 | Main 启动打点（`startup-marks.ts`），新增 `npm run perf:startup`：首次运行 / 空配置 / 300 个会话三种配置，各 5 轮 | 见下表 |
+| P9 | `package.json` 新增 `perf:startup`、`perf:document-parse` | — |
+
+冷启动基线（标准机，中位数 / p95，ms）：
+
+| 阶段 | 首次运行 | 空配置 | 300 个会话 |
+| --- | --- | --- | --- |
+| 启动到输入框可用 | 1284 / 1322 | 1024 / 1040 | 1028 / 1040 |
+| Main 模块加载（index.js 求值） | 414 / 420 | 411 / 420 | 413 / 423 |
+| 本地工具环境初始化 | 154 / 169 | 160 / 163 | 153 / 160 |
+| 知识库初始化 | 240 / 249 | 19 / 22 | 32 / 42 |
+| 助手数据库初始化（同步） | 205 / 206 | 4 / 4 | 14 / 15 |
+| Renderer 导航到输入框出现 | 228 / 233 | 226 / 244 | 224 / 228 |
+
+启动的主要开销是 Main 模块加载（约 415 ms）和本地工具环境初始化（约 155 ms）；首次运行另有约 450 ms 的建库开销。这些只做了测量，没有改动，后续按 P6 拆分延迟加载。
+
+本轮回归：`perf:app` 60 项阈值全部通过（不降速，流式和流式打字长任务均为 0）；typecheck、全量 lint 通过；全量测试中 2 个失败分别为 OpenCode 免费额度 403 的集成用例和 `magic-notes-*` 真实 Electron 测试在整套并行负载下的偶发失败，后者单独运行和 6 个 Electron 布局测试并行连跑 3 次均通过。
+
+### 7.2.1 活动记录增量与分页（2026-10-04，P2/P4/P5）
+
+之前启动时整份读取活动记录（本机约 2.4 万条、10 MB），任何变化 250 ms 后把整份列表 `replace` 回 Main；Main 每次在列表前面插入记录都要重写顺序 JSON。分三次提交改完：
+
+1. **增量保存（`6aab78b`）。** 活动记录移出 App 状态，放进 `activity-store.ts`。领域动作（新增、更新请求、审批、按请求删除、按调用删除、结束请求、对账、清空）修改状态，同时排入对应的契约变更；`activity-sync.ts` 每 250 ms 用 `activityHistory.update` 发送（每次最多 2 万条），失败的变更按原顺序留在队列里，退避重试；退出和卸载前也会刷盘。清空改为新增的 `activityHistory.clear()`，Main 在一个事务里完成。
+2. **Main 分页、汇总、对账（`352da66`）。** 第 57 版 schema 重建 `activity_history_records`：`order_seq`（越新越大，移到最前就分配新的最大值）加上从记录 JSON 生成的存储列（状态、类型、请求、会话、项目、创建时间）和索引。顺序从 `record_order_json` 原样迁移；旧数据里的重复 ID 保留，仍然只显示第一条。`ActivityHistoryRepository` 负责全部 SQL：按索引倒序分页 `page`，`summary` 返回面板原来从整份列表算出的计数、会话标题和会话状态，`reconcile` 用 SQL 关联任务表（追加的说明行由界面传入本地化文本），以及 `clear`。分页和汇总走只读 worker。
+3. **界面只保留已加载的页（`bf9850a`）。** 启动顺序：发送排队的变更，Main 对账，再加载首页（200 条）。打开运行记录页时补足一批（500 条，和以前首屏一样多），“继续显示”先显示下一批，再在后台加载下一页；切换筛选会重新取首页；离开页面只留一批。计数、分组、标题、会话状态和清空数量都来自 Main 的汇总。没加载的记录也照样增量更新：`update` 新增按内容匹配的变更（`upsert-call`、`update-request`、`resolve-approval`、`settle-request`、`remove-request`、`remove-call`），由 Main 在 SQL 里执行，界面对已加载的页用同一份参考实现处理。任务刷新后的对账也改在 Main 里用 SQL 完成。旧 localStorage 记录改成增量变更迁移，界面不再调用 `replace`。
+
+`npm run perf:main`，2.4 万条活动记录，两轮结果一致（括号内为 Main 事件循环最大延迟）：
+
+| 路径 | 之前 | 之后 |
+| --- | --- | --- |
+| 启动读取 | 整份 `get`：14.2 MB，178 ms（198 ms），在 Main 上执行 | 首页 + 汇总：114 KB，16 ms，在 worker 上执行（Main 0.6 ms） |
+| 首页 200 条（同步路径，参考） | — | 1.0 ms（1.3 ms） |
+| 汇总（同步路径，参考） | — | 14 ms（15.6 ms） |
+| 保存 1 条变化 | 整份 `replace`：98 ms（114 ms） | `update`：3.9 ms（6.9 ms） |
+| 每次保存的载荷 | 整份列表（约 14 MB） | 只含变化的记录，与总量无关（单元测试：3 条变化 < 1.5 KB） |
+
+测试：随机动作序列（含翻页、截断、刷盘和注入的保存失败），在真实数据库上与改动前的整份列表逻辑逐步对比，最终数据库与整份 `replace` 的结果一致（含重复 ID 和移到最前）；启动后界面不超过一页；保存载荷只取决于变化的记录（含未加载的）；随机数据集（含重复 ID）下，分页加汇总渲染出的计数、分组、标题、状态和清空数量与整份列表渲染一致；重启后遗留的进行中记录被标为中断，说明文本相同；清空后数据库、界面和汇总都为空；SQL 变更语义与参考实现一致。`perf:app` 60 项阈值全部通过。
+
+后续（2026-10-04）：汇总覆盖全部已加载会话，超过 5,000 个时分多次请求再合并，不再截断（单元测试：5,003 个会话分 5,000 + 3 两次请求，全部有标题和状态）。分组里“会话活动数”统计的仍是已加载的记录，和以前统计已显示的记录一致。
+
+### 7.2.2 Main 写库与启动：真实数据测量（2026-10-04，PERF-15）
+
+用便携版 `dist/GoodBuddy-windows-x64/data` 的副本测量（源目录从不被打开）：`assistant.sqlite` 2.4 GB，175.5 万条任务事件（其中 148 万条子任务进度、1.1 GB），4,812 条消息（metadata 约 400 MB，单条最大 4 MB），2.4 万条活动记录。新增 `npm run perf:write`（`build/run-write-perf.cjs`，按真实数据中最忙一秒的速率 270 条/秒回放真实事件），`perf:startup` 新增 `real` 变体（`GB_PERF_STARTUP_REAL_DATA`，每次启动用新副本，外网请求全部拦截）。
+
+**测到的问题：**
+1. 每次写库都按 `synchronous = FULL` 同步落盘，单次约 2.4 ms，与写入内容无关：子任务进度、工具、文本批、会话保存、活动记录都一样。
+2. SQLite 自动 checkpoint 发生在越过 1,000 页的那次提交里：大库上每隔几百次写入就有一次卡住 Main 100–350 ms（3 轮里 18 次超过 50 ms）。
+3. 启动时两条恢复语句、一条图片操作恢复语句各扫描全部消息的 metadata：在 Main 上同步约 2.3 秒，启动到输入框可用 3.7 秒。
+
+**改动：**
+- **频繁的本地写入改用 `synchronous = NORMAL`**：本地运行事件（生命周期事件 `status`/`done`/`error` 除外）、渲染进程 500 ms 一次的会话保存、活动记录增量。WAL 模式下仍是原子提交，应用崩溃不丢；断电最多丢最近一段这类写入，任何 FULL 提交及其之前的数据不受影响。远程事件（Agent ACK 依赖其持久性）、通道投递、任务状态等其余写入仍为 FULL。
+- **WAL checkpoint 移到 worker 线程**：复用只读查询 worker 的入口，每 250 ms 做一次 PASSIVE checkpoint；运行期间 Main 的自动 checkpoint 阈值提到 4,000 页作为兜底（持续写入时被动 checkpoint 追不上 WAL 重置点），worker 退出即恢复默认 1,000。
+- **启动恢复按索引读候选消息**：第 58 版 schema 新增部分索引 `messages_recovery_idx`（流式中，或 metadata 含未结束的工具、子任务、图片操作状态）；没有用户队列项时跳过按 queueItemId 的全表删除。metadata 只由 `JSON.stringify` 写入，状态总以紧凑形式出现，精确判断仍在候选行上用原逻辑执行。一次性迁移在升级 worker 中执行，真实数据约 2 秒。
+
+**结果（真实数据）：**
+
+| 指标 | 之前 | 之后 |
+| --- | --- | --- |
+| 单次写库 p50（子任务 / 工具 / 文本 / 会话保存 / 活动记录） | 2.2–2.6 ms | 0.1–0.3 ms |
+| 写入期间 Main 最长阻塞（270 条/秒，3 轮） | 8–346 ms，超过 50 ms 共 37 次 | 2–34 ms，超过 50 ms 0 次 |
+| 启动：Main 上的初始化（`assistant-db-init`） | 2,564 ms | 232 ms |
+| 启动：到输入框可用（中位数，4 次） | 3,702 ms | 1,359 ms |
+| 启动：侧栏出现会话 | 4,081 ms | 1,749 ms |
+| 启动期间 Main 最长阻塞 | 2.5–2.8 s | 236–257 ms |
+
+部分索引的代价：metadata 更新时如果新旧值都命中候选条件，要多维护一次索引（4 MB metadata 的更新 36 → 59 ms，233 KB 的 0.7 → 1.6 ms）；不命中时没有额外开销。启动时剩下的约 0.6 s 在本地工具环境探测（已在后台初始化，不阻塞 Main）。
+
+未做：读取最大的会话（407 条消息、42 MB metadata）在 worker 上约 170 ms，不阻塞 Main，但切换到这个会话时要等这么久；需要按需加载 metadata，单独立项。
+
+### 7.3 体验倒退复查（2026-10-03）
+
+逐一复查了所有性能提交对交互体验的影响，并新增原则 P10“体验不倒退”。发现并修复：
+
+| 问题 | 来源 | 修复 | 验证 |
+| --- | --- | --- | --- |
+| “到底部”按钮的平滑滚动动画消失，直接跳到底部 | `fdf7d83` 消息窗口化：贴底跟随、ResizeObserver、锚定修正都会瞬间写入 `scrollTop`，打断平滑滚动；点击时还立即切换窗口导致可见行被卸载 | 滑动期间暂停所有滚动写入，只随视口重新窗口化；到达底部、`scrollend` 或 1.5 秒兜底时再贴底；用户滚轮、按键或点击会接管滚动 | 真实 Electron 逐帧采样，要求有中间帧（旧代码中间帧为 0），连跑 3 次通过；新增单元测试，旧代码失败 |
+| 消息滚出可见区后丢失状态：待回答问题里已选的选项和输入的内容、展开的工具详情和推理、Mermaid 重新绘制并显示“加载中” | `fdf7d83` | 有待回答问题或待审批的行、用户交互过的最近 8 行、选区两端所在的行保持挂载；Mermaid 按“主题 + 源码”缓存渲染结果（最多 64 个） | 单元测试，旧代码失败 |
+| 跨多条消息选择文本时，选区起点被卸载；复制时只拿到已挂载的文字 | `fdf7d83` | 选区两端所在的行保持挂载；复制时，未挂载的消息用原文补全 | 单元测试 |
+| 侧栏在上方插入、删除、置顶或 5 秒重排时，可见的会话行跳动 | `663aa85`，窗口化关闭了原生滚动锚定 | 会话 id 变化时，在绘制前按第一条可见行恢复位置；列表在顶部时不锚定 | 单元测试，旧代码失败 |
+| 笔记、文件树、知识库文档表格的锚定修正可能和浏览器原生锚定冲突 | `b2eb86a` | 窗口化状态下关闭 `overflow-anchor` | 单元测试 |
+| 终端打字回显多等一帧；点击“清屏”前到达的输出在清屏之后才显示 | `f4458af` | 空闲时立即写入，只合并同一帧内后续到达的输出；清屏前先写完待写入的输出 | 单元测试 |
+| 远程 Runtime 流式输出最多 50 ms 一批，显示一顿一顿 | `d859cbf` | 合并间隔改为 16 ms；写库成功后立即转发，仍然是先写库再转发 | 单元测试 |
+| 流式输出时从侧栏复制或导出会话，可能缺最后不超过 250 ms 的文字 | PERF-13 流式缓冲 | 复制、导出前先把待同步的流式文字刷进状态 | 单元测试，旧代码失败 |
+
+检查后没有问题：CSS 动画和过渡没有被删改；其余 `scrollIntoView` 的行为和原来一致；标题跑马灯、侧栏 5 秒重排的悬停冻结、重命名和菜单行保持挂载；输入框自动增高；Markdown 和 KaTeX 渲染结果。快速大跨度跳转是否出现空白帧也做了实测：在 `perf:app` 滚动场景中加了检查，CPU 降速 4 倍时 10 次跳转中空白帧为 0，所以没有改动。
+
+已知限制（不是倒退，原来也没有）：读屏软件的浏览模式访问不到未挂载的消息；应用本身没有页内查找功能。
+
+修复记录：文件树窗口化最初以 `.assistant-sidebar__body` 为滚动容器，但真实布局中滚动的是停靠的 `.workspace-files__files-view`，真实 Electron 测试发现后改为优先使用后者。
+
+### PERF-14 状态
+
+- **优先级 / 状态：** P2 / 进行中（消息时间线和侧栏已窗口化；页内查找等限制未解决）
+- **实施条件：** `PERF-13` 完成会话与消息迁移，行组件 props 已稳定。
+- **范围：** 消息时间线和会话侧栏优先；保留滚动位置、跳转、展开状态和“加载更早消息”语义。
+  替换新面板分两步渲染（`09c415b`）；侧栏 5 秒重排状态随侧栏迁出 App。
+- **验收：** 5,000 条消息和 1,000 个会话场景下 DOM 节点数有界，滚动与切换指标改善。
+
+### PERF-15 存储接口异步化
+
+- **优先级 / 状态：** P1 / 进行中（热点读走 worker；高频写降为 NORMAL、checkpoint 移出 Main、启动恢复按索引，见 7.2.2；接口异步化未开始）
+- **范围：** 在原进程内把 `AssistantDatabase`、`KnowledgeDatabase` 等对外接口改为异步，
+  调用方全部 `await`；会话列表只返回摘要，搜索下推到 SQL，活动记录改为增量追加。
+  远程 Runtime 实时事件改用已有的 `appendRemoteTaskEventsBatch` 批量写入，不再逐条同步事务。
+  Story Graph 检索先补测耗时，扫描规模设上限，匹配尽量下推到 SQL。
+- **验收：** 行为与测试不变；`PERF-11` Main event-loop 延迟不变差。
+
+### PERF-16 数据进程
+
+- **优先级 / 状态：** P1 / 待开始
+- **实施条件：** `PERF-15` 完成，调用方已全部异步。
+- **范围：** 新增独占 SQLite 的 `utilityProcess`，承接会话、知识库、向量检索、Story Graph
+  （含 Agent 主动调用的检索）、远程 Runtime 事件持久化、活动记录及文档解析；Main 只转发；
+  保证同一时刻只有一个写入方。吸收 `PERF-06` 的范围。
+- **验收：** 大知识库检索、会话列表和文档导入期间 Main event-loop 延迟达到批次目标；取消、
+  崩溃恢复和迁移语义不回退。
+
+### PERF-17 架构守护
+
+- **优先级 / 状态：** P2 / 待开始
+- **范围：** lint 禁止 `src/main` 使用同步文件 API 和在数据进程外引用 `DatabaseSync`；禁止
+  组件直接订阅 `window.goodbuddy.*.on*`；限制 `App.tsx` 规模；`PERF-11` 关键指标设置回归阈值。
+- **验收：** 违反规则的改动在 lint 或基准阶段失败。

+# GoodBuddy Agent 0.15.3 更新内容
+
+## 功能更新
+
+- **查询故事与经验**：配套 Desktop 0.15.9，远程 Story Graph 工具现在接受故事和经验对象，可读取故事事件以及经验的形成和应用依据。工具说明引导 Agent 在继续既有工作时按需查询，是否调用仍由模型决定，经验应作为参考而不是指令。
+
+## 使用说明
+
+- 先升级 Desktop **0.15.9**，再下载并更新 Host；已有 Agent 进程不热更新。
+- 读取仍受监督者开关、Runtime 分配和项目范围约束；没有新增写入权限或自动全量上下文注入。
+- Linux x64、Linux arm64、macOS arm64 三平台；Node **24.19.0**、OpenCode **1.18.29**、Continue **1.5.47** 不变。
+- Agent 独立发布，签名和完整性验证保留，不替代 Desktop Latest。
+
+# What's New in GoodBuddy Agent 0.15.3
+
+## Features
+
+- **Query stories and experiences**: With Desktop 0.15.9, remote Story Graph tools accept story and experience objects to read story events and the evidence behind an experience's formation and applications. Tool descriptions guide Agents to query when continuing earlier work, but actual tool use remains model-dependent, and experiences are advice rather than instructions.
+
+## Usage Notes
+
+- Upgrade to Desktop **0.15.9** before downloading and updating the Host; existing Agent processes are not hot-updated.
+- Reads remain subject to Supervisor enablement, Runtime assignments, and project scope, without new write permissions or automatic full-graph context injection.
+- Targets are Linux x64, Linux arm64, and macOS arm64; Node **24.19.0**, OpenCode **1.18.29**, and Continue **1.5.47** are unchanged.
+- Agent is released separately with signature and integrity checks, without replacing Desktop Latest.
