 - 当前项目已配置 CodeGraph MCP；结构性代码问题优先使用 `codegraph_*` 工具：`codegraph_search` 查符号，`codegraph_callers` / `codegraph_callees` 查调用关系，`codegraph_impact` 做影响分析，`codegraph_context` / `codegraph_explore` 获取聚焦上下文，`codegraph_files` 查看索引文件结构，`codegraph_status` 检查索引健康。
 - CodeGraph 是当前开发态代码图主工具；代码改动后运行 `codegraph sync .`，大范围重构、排除规则变化或索引异常时运行 `codegraph index . --force`。只有查找字面文本、日志字符串、注释原文，或已经明确目标文件时，才优先用 `rg` / 直接读文件。
 
+## Reference-Code 快速对照流程
+
+- 对照 VSCode / Sidex / Zed / Lapce / Tiptap 等参考实现时，先确认实际源码目录和对应 `.codegraph/` 是否存在；当前优先参考 `/mnt/Data1T/mnote/reference-code/sidex-main` 的完整 VSCode 工作台源码，`reference-code/vscode` 只作为裁剪版辅助证据。
+- 每次只围绕一个功能切面做对照，例如 Explorer 打开目标、编辑器 tab、资源生命周期、拖拽排序、快捷键或 overlay 定位；不要一次性抽象迁移整个参考项目。
+- 推荐步骤：`codegraph_status` 确认索引 -> `codegraph_search/context` 找参考实现入口 -> `codegraph_callers/callees` 看调用链 -> 对应查 MNote 当前链路 -> 映射到 Rust kernel / mnote-web / 前端 host 的正确边界 -> 补 smoke 或测试。
+- 对照结论必须区分“可直接采用的交互/状态模型”“只适合作参考的实现细节”“不符合 MNote local-first / tree-first 主线的内容”；不要把参考项目中的 UI 层状态当成 MNote 的新事实源。
+
 ## 常用命令
 
 - 根目录热启动：`npm run desktop:hot`

 - Use native search only for literal text, comments, log messages, or after a specific file is already identified.
 - Keep the project index fresh in development: run `codegraph sync .` after code changes; use `codegraph index . --force` when the index looks stale or after broad restructuring.
 
+## Reference-Code Comparison
+
+- Reference implementations live under `/mnt/Data1T/mnote/reference-code/`; prefer `/mnt/Data1T/mnote/reference-code/sidex-main` for VSCode workbench comparisons because it contains the fuller `src/vs/workbench` tree, while `reference-code/vscode` is a smaller auxiliary snapshot.
+- Compare one feature slice at a time, such as explorer open target, editor tabs, resource lifecycle, drag-and-drop ordering, keybindings, or overlay placement.
+- Fast workflow: check `codegraph_status` for both projects, locate reference entry points with `codegraph_search/context`, inspect callers/callees, inspect the matching MNote chain, then map the result onto Rust kernel / `mnote-web` / frontend host boundaries.
+- Always classify findings as: reusable interaction/state model, reference-only implementation detail, or incompatible with MNote local-first / tree-first architecture.
+
 ## Conventions
 
 - **Smoke test pattern**: standalone Playwright scripts under `scripts/task-*.js` using a shared harness (`ensureAuthenticated`, `createTempDocument`, `cleanupDocuments`). All use `"use strict"` and `require("playwright")` (`scripts/task110-page-title-single-truth-smoke.js:1-4`).

+
+## 1. 目标
+
+把资源类型识别和打开策略从分散 if/else 收口为轻量 resolver，并补齐当前缺失的类型 smoke。默认目标是主编辑区 resource tab；右侧边栏和新窗口必须作为显式目标保留。

+# 12 Sidex / VSCode Workbench 对照审查 v1
+
+> 状态：process
+>
+> 日期：2026-05-20
+>
+> 范围：`reference-code/sidex-main` 对照 MNote 当前主编辑区、资源 tab、File Tree、资源生命周期和 smoke 覆盖。
+
+## 1. 审查方法
+
+本轮使用 CodeGraph 与只读 subagent 并行审查，优先对照 `/mnt/Data1T/mnote/reference-code/sidex-main`，因为该目录包含较完整的 VSCode workbench 源码。`reference-code/vscode` 当前更像裁剪版快照，只作为辅助证据。
+
+审查按功能切面展开：
+
+- Editor / tab：`EditorService.openEditor`、`EditorGroupModel`、`EditorGroupView`、`MultiEditorTabsControl`、`OpenEditorsView`。
+- Explorer / file actions：`ExplorerService`、`ExplorerView`、`fileActions`、`ResourceFileEdit` / `IBulkEditService`。
+- MNote 对应链路：`mnote-web` 的 `web_shell.rs`、`layout.rs`、`tree.rs`、`local_folder_source.rs`、`resource_trash.rs`、`onlyoffice.rs`、`leptos-tiptap-spike`。
+
+## 2. Sidex / VSCode 可借鉴模型
+
+- Explorer 打开文件不是按 UI 分支散落处理，而是统一交给 `IEditorService.openEditor({ resource, options }, ACTIVE_GROUP / SIDE_GROUP)`。
+- `EditorGroupModel` 是 tab/editor 列表真相层，维护 `editors`、`active`、`preview`、`sticky`、`transient`、MRU 和 selection，并发布 open / close / move / dirty / label 等模型事件。
+- `EditorTitleControl` / `MultiEditorTabsControl` 只是消费模型做渲染、滚动、reveal active、DnD、右键菜单和 tab action，不承载资源事实。
+- `OpenEditorsView` 监听 editor group model，与 active editor、visible editors、dirty/label 状态联动。
+- Explorer 文件生命周期通过 `ResourceFileEdit` + `IBulkEditService` 聚合执行，并处理 dirty working copy、readonly、trash / permanent delete、undo label、cancel 和失败 fallback。
+
+## 3. MNote 当前链路
+
+- 主文档页由 `document_page_shell` 生成，SSR 初始只有固定 page tab、resource tab host 和可选 secondary pane。
+- `resourceTabRegistry` 是浏览器内存 Map，`openResourceInActiveTab` 按 `objectIdentity` 去重并动态创建 tab/panel；关闭时直接 unmount、remove、delete。
+- 文件树点击在 `layout.rs` 中分发：document / markdown 页面走 `navigateToDocument`，asset 触发 `tree.asset.open`；local office 可进 resource tab，Convex office 仍可能新窗口，mindmap 走独立 object shell。
+- local_folder executor 已能处理 Markdown、目录、raw file 的 create / rename / copy / move / delete / restore / purge，但 filetree runtime 的打开目标模型和资源生命周期模型仍未完全对齐。
+- resource lifecycle 仍散在 tree command、resource_trash 兼容 route、layout 内联 JS 多条路径。
+
+## 4. P0 缺口
+
+### P0-1 统一 editor input / editor group / active editor 模型缺失
+
+MNote 当前 page、secondary pane、resource tab、mindmap shell、OnlyOffice 新窗口分别走不同状态链。`resourceTabRegistry` 只存在于页面内存，不能被 Sidebar、Open Editors、快捷键、持久化恢复或 watcher 统一消费。
+
+建议：先实现 MNote 轻量版 `EditorInput` / `EditorGroupState`，只覆盖 active group 内的 page/resource editor，不照搬 VSCode 完整 DI 和多 group grid。
+
+### P0-2 resource tab 关闭缺少 dirty / saving / conflict 防护
+
+`closeResourceTab` 直接释放 view/session 并移除 DOM，但同一文件中已经存在 `session.dirty`、`saving`、`hasExternalConflict` 等状态。关闭脏资源、保存中资源或外部冲突资源需要最小防护。
+
+建议：关闭前先检查 session 状态；脏资源优先触发保存或阻止关闭并给出确认；保存中/冲突状态不能静默释放。
+
+### P0-3 资源打开策略不一致
+
+local office 可进入主编辑区 tab，Convex office 仍可能新窗口；mindmap 总是 object shell；部分非本页 code/text attachment 会 `window.open`。这和“默认主编辑区 tab，显式新窗口例外”的当前目标不一致。
+
+建议：引入统一 `openResourceEditor(input, target)`，把 `active-tab`、`side`、`new-window` 作为显式目标，并把 resource kind 解析集中在 resolver。
+
+### P0-4 File Tree 打开目标与资源生命周期模型不对齐
+
+`filetree_runtime::OpenTarget` 只能表达 document / index / asset / asset-folder，不能完整表达 raw local file、directory、arbitrary resource；但 local_folder executor 已支持 raw file / directory lifecycle。
+
+建议：扩展 open target / resource identity 合同，至少能稳定表达 `local_file`、`directory`、`mindmap`、`table`、`office`、`image` 等资源类型。
+
+### P0-5 resource lifecycle 仍多入口分散
+
+资源删除/恢复/永久删除仍由 tree command、resource_trash route、layout 内联 JS 分流处理。云端 asset、mindmap、table、本地 raw file 的路径不完全统一，容易造成垃圾箱、刷新、tab 状态不同步。
+
+建议：继续推进 `tree.resource.*` cutover，旧 URL 只作为兼容 alias；前端也应逐步走统一 resource command client。
+
+## 5. P1 缺口
+
+- local_folder `move` 丢弃 `sortOrder`，拖拽排序与持久顺序语义不闭环。
+- resource tab active 状态只改 DOM，不同步 URL、sidebar active row、可恢复状态。
+- tab identity 混用 `objectIdentity / assetId / href / resource:file:<rootUri>:<path>`，需要 canonical resource identity。
+- mindmap 仍是独立 object shell，不是 main editor group 内的 editor kind。
+- secondary pane 与 main tab 是两套概念；长期应映射为 side target / side group 语义。
+- delete 缺少 dirty / readonly / undo / fallback 统一动作层。
+- paste / right-click paste 目标模型不完整；外部 drop 对二进制文件支持不足。
+- smoke 偏“资源存在 / 不闪烁”，缺少 editor workbench 语义断言。
+
+## 6. P2 缺口
+
+- tab strip 缺少键盘 roving tabindex、左右切换、关闭快捷键、MRU 回退。
+- tab overflow / reveal active / multi-row / context menu / close others 等能力较弱。
+- `.txt` / `.json` / `.ts` / PDF / image 等类型 smoke 矩阵不完整。
+- PDF badge 当前与 ppt 复用，资源类型与显示颜色语义应拆开。
+- File Tree 上下文菜单仍有英文和禁用项暴露实现缺口。
+- trash modal 与 resource command 仍是并行入口，需要继续收口到统一资源生命周期视图。
+
+## 7. 不建议照搬
+
+- 不照搬 Sidex / VSCode 的 DI service 容器。
+- 不照搬完整多 editor group grid；MNote 当前只需要 active tab + side target 的轻量模型。
+- 不照搬 Monaco / TextModel 作为 Markdown 文档事实源；MNote 主编辑仍是 tiptap / Page Aggregate / local Markdown。
+- 不照搬 Extension Host、ContextKey 全体系和完整 UndoRedoSource。
+- 不把参考项目 UI 层状态当成 MNote 的新事实源；MNote 的树、资源归属、生命周期仍以 Rust kernel / local-first 合同为准。
+
+## 8. 执行拆分
+
+本 review 拆分为三份执行 checklist：
+
+- `design/05-editor-mainline/process/5-16-editor-group-resource-tab-safety-checklist-v1.md`
