+- Desktop `0.15.9` adds shared review progress, stories, experiences, and spiral
+  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

+# Desktop 0.15.8 / Agent 0.15.2 发布准备
+
+日期：2026-10-02。Desktop 基线 `v0.15.7`，Agent 基线 `agent-v0.15.1`；
+已提交源码固定为 `b1129cedec5e4890d82fcddc186b13467f466a6f`。
+仅纳入四个已提交功能修正及本次必要发布准备，不提交已有 Story Graph、
+会话监督设计或宣传文章等未提交文件。
+
+## 范围
+
+- `dd29f30`：保存会话图片到本机或 Host、设置中列出图像工具。
+- `f4d8fe7`：新记录取消、编辑焦点返回、笔记正文使用可用宽度。
+- `2e5c348`：缺失内置浏览器设置时默认启用，保留已保存配置。
+- `b1129ce`：缺失磨砂外观字段时默认开启，保留已保存配置。
+- 数据库仍为 schema 52；Desktop 标准六平台，无 LoongArch。
+- Agent 保存路径涉及守护进程、工具声明与桌面图像二进制回复，升至 0.15.2，
+  最低 Desktop 0.15.8；协议主版本及 Runtime 锁版本不变。
+
+## 当前源码共享 Host 验证
+
+共享 Linux x64 Host 的现有 SSH 固定身份可达。在独立 `/root/tmp` 目录运行
+当前源码 AgentImageToolMcp，通过真实 SSH 传递工具消息，与 Desktop 的
+MainImageToolSession、ImageGenerationService、真实 SQLite 会话协作。
+图像为本轮生成的合法随机 PNG，196992 字节，超过单个 128 KiB 分块。
+
+保存后的 Host 文件 SHA-256 与 Desktop 原始内容相同；默认覆盖拒绝、明确覆盖成功、
+其他会话图片 ID 拒绝、Ask 写入拒绝且无文件落盘。共 8 个回复帧，
+最大 174892 字节，低于 256 KiB 上限。外部模型调用 0 次。
+这是生产保存服务与 Agent MCP 的真实 Host 工具层验证，不冒充完整 App、
+模型自动选工具、安装包或三个 Host 架构验证。使用 SSH 流作为该探针传输；
+未改变用户工作区、产品配置或 Host 已安装 Agent。
+
+临时探针最初因打包 Zod 初始化顺序、混入仅 Desktop 依赖而无法启动，
+修正探针依赖边界后验证通过；这些失败不计为产品模型调用或产品修复。
+探针和包不进入仓库。用户要求不跑本地测试套件，精确候选由 CI
+执行全量验证和生产构建后，才允许打 Desktop 和 Agent 不可变标签。
+
+## 发布核对
+
+中英文 FEATURES、Desktop 与 Agent 双语说明必须与上述实现边界一致。
+只暂存必要发布文件，保留工作区用户文件；双远端核验候选和标签一致。
+公开验证包括六平台 Desktop、三平台 Agent 签名目录、GitHub/OSS 同步及 Latest 分离。
+
+## 首轮 CI 修正
+
+`20317c2`：Agent CI `36960575058` 成功；Desktop `36960575157` 为
+5620 通过、59 跳过、4 失败，构建未执行。
+Obsidian 专项 IPC fixture 未安装浏览器服务，显式关闭无关浏览器能力；
+MCP 列表断言纳入新增图像卡片的数量和名称；覆盖层原生点击先将控件居中，
+避免磨砂顶栏覆盖 `nearest` 保留在顶部的控件，并补充命中遮挡诊断。
+保留所有业务、覆盖层和原生交互断言，不改变产品默认值、关闭沙箱或跳过测试。
+这些修正由新候选 CI 验证。
+
+`5368e0e` 的 CI `36962139369` 中上述四项通过，余下新记录取消焦点用例失败，
+5623 通过、59 跳过、1 失败。测试用 `fireEvent.click` 点击取消不会像原生点击
+那样移动焦点，确认框记住的仍是先前的返回总览按钮。用例先等打开详情的焦点完成，
+明确聚焦取消按钮后再点击，并等继续编辑实际聚焦编辑器后进行下一步；
+保留放弃草稿后回到记录与未保存新记录的断言，不改产品焦点规则或延长超时。

+# Desktop 0.15.9 / Agent 0.15.3 发布准备
+
+日期：2026-10-03。Desktop 基线 `v0.15.8`，源码
+`50481deaa1f7d17184500bb6f5abb3e1a0c8bbd5`，37 个提交、163 个文件。
+检查时工作区干净，范围仅为已提交实现与必要发布准备。
+标准六平台 Desktop、三平台 Agent，不含 LoongArch。
+
+## 范围与边界
+
+- 监督共享时间线、故事归属与人工调整、经验抽取、故事回顾与心跳建议；
+  平铺与时间螺旋、紧凑图谱控件及 WebGL 生命周期修复。
+- schema 53～56：合并既有进度，增加故事、经验及建议类型，保留历史结果。
+  旧数据库副本验证和模型质量抽查见[监督进度](../features/conversation-supervision/progress.md)，
+  不将 schema 53 的单库耗时当作本轮完整迁移保证。
+- 会话外部存储、侧栏和消息窗口化、Markdown 缓存、只读 Worker、活动差量写入、
+  远程事件 checkpoint 批次持久化；保留丢失焦点、滚动、去重与提交顺序检查。
+- 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：
+
+| Runtime / 模式 | 批次 | 事件 | checkpoint |
+| --- | ---: | ---: | ---: |
+| OpenCode Ask | 3 | 4 | 2 |
+| 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”。
+
+## 2026-10-02 时间螺旋显示经验节点
+
+对应 [3D 概念](../story-graph/3d-concept.md) 中的桶外经验节点。
+
+实现：
+
+- `experienceLinks()`（`story-graph-3d-model.ts`）：经验在当前层中，从最早形成依据所在的木片，连到之后第一个在另一片木片上的应用。只在同一片木片里用过的、应用不晚于形成的、依据不在当前层的经验不画。每层最多 6 条，按应用到的不同木片数排序。
+- 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。
+
+验证：
+
+- `story-graph-3d-model.test.ts` 新增 1 项（只连到跨木片的后续应用、只出现一次、层外依据与倒序应用排除、上限）。相关组件测试 3 个文件 32 项通过，Web 类型检查、相关 ESLint 通过。
+- Electron 实测（生产组件，第 5 步数据副本的 46 个故事、38 条经验；1440 浅色、390 深色）：无报错、无横向溢出；根层 3 条、goodbuddy 层 6 条跨木片经验；从列表选中和在画布上点中菱形都能打开经验。
+- 38 条经验中，在当前数据里能形成跨木片连线的只是少数，其余只在同一故事中形成或应用，不在螺旋上显示，仍可在“经验”页签中查看。
+
+## 2026-10-02 故事线模型第 5 步：工作回顾按故事组织
+
+对应[故事线模型改造设计](./storyline-model-design.md)第 5 步“工作回顾页”。
+
+实现：
+
+- 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。
+
+## 2026-10-02 故事线模型第 5 步：心跳故事建议与 MCP 故事、经验查询
+
+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。
+- 真实数据（第 4 步修正后运行的数据副本，`npx jiti scripts/story-suggestions-deepseek.mjs <db> .env.deepseek.local <dir> 7`，DeepSeek `deepseek-flash`；数据只有约 13 天，阈值用 7 天，“现在”取最后事件时间）：
+
+| 运行 | 规则候选 | 调用 | 结果 |
+| --- | --- | --- | --- |
+| 第 1 轮（故事候选排在未决事项之后） | 20 条未决事项，0 条故事候选 | 2 | 故事候选被 20 条上限挤掉，因此改为故事候选优先 |
+| 第 2 轮（暂无进展不限量） | 20 条暂无进展 | 2 | 13 天的数据里大量故事“停滞”，一次挤满上限，因此加每次 3 条的限制 |
+| 第 3 轮（经验按每个实体匹配） | 3 条暂无进展、17 条可用经验 | 2 | 同一经验指向 5～8 个故事，大多经由“监督者”这类通用实体匹配，因此改为排除通用实体、每条经验只指向一个故事、每次最多 3 条 |
+| 第 4 轮（最终规则） | 3 条暂无进展、3 条可用经验、14 条未决事项 | 2 | 每次请求 6 条故事候选，都不含来源定位；建议都带故事，经验建议都带经验 |
+
+  - 最终规则下的可用经验例如“长任务超时或中断先查取数与分批根因，不以延长超时或调并发修复”指向“回顾算法与并发设置”、“提交只纳入本次相关改动”指向“自动监督开关与设置”。是否真正适用未人工逐条核对。
+  - 再次生成时没有重复任何待处理建议；只补上了上一次被 20 条上限挤掉的未决事项（1 次调用）。
+  - MCP：全局范围搜到 6 个相关故事、9 条相关经验；一个功能的上下文返回 96 个事件（含子线索），一条经验返回 5 个依据事件。
+
+边界：是否在普通对话中主动查询故事与经验，取决于 Agent 是否调用工具，未做额外注入。
+
+## 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 |

+
+## 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 |

+高度：容器宽度不小于 861px 时，图谱这一行的高度等于窗口可见高度减去图谱顶部位置，并在底部保留约 24px 边距（不小于页面底部内边距），最低 660px（再矮平铺图的文字会小于 11px，这时改为页面滚动）。三栏时整页不再出现纵向滚动；左侧列表和右侧详情在这一行内独立滚动，滚动只影响自身，不带动页面。中间画布列不出现滚动条：标题栏和底部单行“事件浏览”栏之外的高度全部给图，平铺与时间螺旋一致。画布标题为“事件与知识”，下方一行小字依次显示图谱范围、时间区间、生成时间和事件/实体数，刷新为标题栏右侧图标按钮；图谱上方不再单独占一行显示范围与时间。没有图谱数据时，刷新按钮保留在页签顶部。图例默认收起，从标题栏“图例”按钮打开，浮在画布右上角，可用 X 关闭；可见事件与实体数量常驻画布左下角。两栏（861～1190px）时第一行按同样方式填满，详情换到下一行，保持自然高度并随页面滚动。单栏保持原有页面滚动和列表 320px 上限。窗口大小或图谱上方内容（提示、工具栏）变化时重新计算。

 实体及其影响连线复用现有 `--graph-node-*-border` 令牌；颜色用于辅助辨认实体，不代表故事分类或确认状态。选中项加粗并突出连线，其余节点降低图形强调度但保留可读文字。详情分为名称与说明、图谱关联、确认操作和来源，来源正文按需读取。图例常显，读图说明可展开。
 
 画布每批最多显示 8 个事件、6 个实体；同时间事件分开排布。列表保留全部返回记录和完整名称，选择实体会定位到真实关联事件所在批次，选择关系会优先显示两端实体。滑块明确命名“事件浏览”，只切换当前事件，不还原实体历史状态，也不宣称完整历史回放。当前接口返回单条故事线，不复制 Demo 中的三条模拟故事。后续视图规划见[图谱设计](../story-graph/prd.md)。

+# 下一版 3D 故事线图谱概念
+
+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。
+
+## DIKW 与阅读路径
+
+| 层次 | 表达 |
+| --- | --- |
+| D | 可追溯的原始记录 |
+| I | 时间螺旋上的事件片段 |
+| K | 木片串联的故事及其形成的认识 |
+| W | 从早期故事形成经验及适用条件，关联到后来其他故事中的应用 |
+
+沿螺旋查看某阶段发生的事情；沿木片查看一件事如何跨阶段发展；跨木片查看经验如何被使用、验证或修正。普通相关性不能直接标为智慧。

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

+### 7.1 架构级界面性能改造（批次 3C）
+
+2026-10-02 的架构评审确认，界面卡顿的主要来源是架构组织方式，而不是 Electron 或 GPU：
+
+- **Renderer 单组件状态：** `App.tsx` 约 11k 行，`App()` 内有 123 个 `useState`、69 个
+  `useEffect`。会话、消息、草稿、任务和设置都在其中，输入和每次流式 flush 都会重新执行
+  整个 App 函数体；多个大面板未 memo，隐藏的 keep-alive 视图也会参与渲染。
+- **Main 同步存储：** 全部 SQLite 访问使用 Main 线程的 `DatabaseSync`，包括全表向量扫描、
+  会话列表与搜索、Story Graph 读取；PDF/Office 解析和附件同步文件 IO 也在 Main。
+- **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。

+
+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。
+
+### 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

+
+#### 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 |
+
+### 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 / 待开始
+- **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 0.15.2 更新内容
+
+## 功能更新
+
+- **把会话图片保存到 Host**：配套 Desktop 0.15.8，在 Execute 模式中使用 `save_image`，可把当前会话中已上传或生成的图片保存到 Host 的指定绝对路径。Agent 分块接收 Desktop 中的图片并在 Host 写入，默认拒绝覆盖已有文件，只有明确指定覆盖时才替换；Ask 模式不能写入。
+
+## 使用说明
+
+- 先升级 Desktop **0.15.8**，再下载 Agent 并更新 Host；已有进程不热更新。
+- 支持 PNG、JPEG 与原格式 WebP，不支持转换为 WebP；只接受当前会话可访问的图片，不下载服务商返回的图片 URL。
+- 提供 Linux x64、Linux arm64 和 macOS arm64 包。Node **24.19.0**、OpenCode **1.18.29**、Continue **1.5.47** 不变。
+- Agent 独立发布，不替代 Desktop Latest，保留签名与完整性验证。
+
+# What's New in GoodBuddy Agent 0.15.2
+
+## Features
+
+- **Save conversation images on the Host**: With Desktop 0.15.8, use `save_image` in Execute mode to write an uploaded or generated image from the current conversation to an absolute path on the Host. Agent receives the image from Desktop in bounded chunks and writes it locally on the Host, refusing to replace an existing file unless overwrite is explicitly requested; Ask mode cannot write files.
+
+## Usage Notes
+
+- Upgrade to Desktop **0.15.8** before downloading Agent and updating the Host; existing processes are not hot-updated.
+- PNG, JPEG, and unchanged WebP are supported; conversion to WebP is not. Only images accessible to the current conversation can be saved, and provider-returned image URLs are not downloaded.
+- Packages cover Linux x64, Linux arm64, and macOS arm64. Node **24.19.0**, OpenCode **1.18.29**, and Continue **1.5.47** remain unchanged.
+- Agent is published separately without replacing Desktop Latest, retaining signature and integrity verification.

+# 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.
