Closes #716

依赖 #709:本 PR 基于 feat/renderer-sidebar-thread-nesting 分支,差异中包含 #709 的两个提交。#709 合并后只剩最后一个提交 feat(renderer): offer to archive child threads with their parent。

变更

  • 触发:按 Host 订阅 app-server 的 thread/archived 通知。父 Thread 归档完成后才处理,所以任何归档入口都适用,父 Thread 的归档不会被阻塞;只有拥有焦点的窗口响应。
  • 询问与设置:默认弹出 Desktop 样式的模态对话框(codex-dialog),列出未归档子 Thread 数量和最多 3 个标题,按钮为“仅归档父会话” / “同时归档 N 个子会话”,可勾选“记住我的选择”。设置 › 通用 › 新增“侧边栏”分组,“归档父会话时”可选每次询问 / 总是归档子会话 / 从不归档子会话。偏好保存在 Renderer localStorage(codexhost.archive-children.v1)。
  • 子 Thread 范围:RendererSidebarThreadTree.liveDescendants 复用侧边栏嵌套的委派和 native Fork 关系,递归计算当前列在侧边栏中的后代;官方 subagent 不受影响。
  • 归档方式:逐个调用子 Thread 侧边栏行自身的 onArchive(即归档按钮使用的函数),置顶、worktree 和撤销提示与手动归档一致;不直接调用 RPC,不写存储。每个子 Thread 等待自己的 thread/archived 通知或行消失后再继续,子 Thread 的通知不会再次触发级联。
  • 失败:没有归档入口或 15 s 内未完成的子 Thread 记为失败,其余继续处理,最后在左下角提示未归档的子 Thread。
  • 中英文文案;文档 docs/architecture/sidebar-archive-children.md。

已知边界

  • 只处理当前渲染在侧边栏中的子 Thread(未加载或所在分组折叠的不计入)。
  • 撤销父 Thread 的归档不会恢复子 Thread;每个子 Thread 有自己的撤销提示。
  • 只修改 Renderer,无需更新 Host;需重启 CodexHost 加载新 Renderer。

验证

  • npm run typecheck、npm run lint、npx prettier --check . 通过。
  • npx vitest run --config tests/vitest.config.js packages/renderer-extension:88 个文件,985 个测试通过。新增 renderer-sidebar-archive-children.test.ts、renderer-archive-children-preference.test.ts,扩展 renderer-sidebar-thread-tree.test.ts、renderer-model-client.test.ts。
  • Headless Chrome 加载打包后的模块与模拟侧边栏:对话框以模态打开,中文文案正确;勾选“记住我的选择”并同时归档后偏好写为 always;两个子 Thread 通过各自的 onArchive 归档,没有归档入口的子 Thread 出现失败提示;设置页渲染“侧边栏”分组,切回“每次询问”后清除偏好。
  • 尚未在真实 Codex Desktop 中端到端验证。

Indent CodexHost-dispatched child threads and forked threads under their
parent in the Codex Desktop sidebar, with an expand/collapse toggle on
parents that have children.

- Add the read-only `codexhost/thread/relation/list` host method. It
  resolves the parent from the persisted Delegation record first and the
  recorded fork source second, and never writes to the official App
  Server.
- Read native Codex fork parents from `thread/read` (`forkedFromId`)
  for Codex-owned threads, skipping official subagents that Desktop
  already nests.
- Install a sidebar thread tree on the existing renderer binding. It
  reapplies CSS order, indentation and visibility to native list items
  on every observed mutation, so React re-renders cannot drop the
  layout, and it never moves or clones native nodes. Child rows keep
  native navigation; the toggle stops propagation.
- Fall back to ownership data when the host predates the new method.

Fixes BytePioneer-AI#708

Signed-off-by: Vincent <1729065730@qq.com>
Codex Desktop files every thread in exactly one sidebar list and a new
fork does not inherit the Pinned section, so the fork of a pinned thread
is rendered in Recents or a project list while its parent stays in
Pinned. The tree only nested entries within one list, which left those
forks at the top level.

Plan all sidebar lists together. A parent in the same list still wins;
otherwise a child and its subtree are shown in the list of their root
ancestor. Desktop owns the native list items, so the native child stays
in place, hidden, and a CodexHost-owned mirror is appended to the
parent's list and positioned with CSS order and indentation. The mirror
is a sanitized clone without row identity, keyboard-cycle or drop-target
attributes; it is re-cloned when the source item changes, and click,
double-click, auxiliary click, context menu, Enter and Space are
replayed on the matching node of the native item. Only threads shown
once across all lists move, cross-list cycles stay in place, and
mirrors are removed when the parent leaves the sidebar or on dispose.

Signed-off-by: Vincent <1729065730@qq.com>
When a sidebar parent thread is archived, CodexHost can now archive its
unarchived Delegation and native Fork descendants as well. The relations
are the ones the sidebar tree already uses, so official subagents are
unaffected.

- Subscribe to app-server thread/archived notifications per Host, so every
  archive entry point is covered and the parent archive is never blocked.
  Only the focused window reacts.
- Ask with a Desktop-styled modal by default. A "remember my choice"
  checkbox stores the answer; Settings > General > Sidebar exposes the
  same preference (ask, always, never).
- Archive each child through its own sidebar row onArchive handler, the
  same path its archive button uses, so pins, worktrees, and undo match a
  manual archive. Children are archived one at a time and confirmed by
  their own notification or row removal; failures are reported in a
  notice without affecting the parent or the remaining children.
- Add RendererSidebarThreadTree.liveDescendants and an onHosts hook, and
  document the behavior and its limits.

避免子会话的迟到通知再次触发级联。

轮询确认子会话已移除后,finish() 会删除 expected 中的 key。此后到达的 thread/archived 通知不再命中 expected,会被当作新的父会话归档处理。如果该子会话仍有列出的后代,threadArchived 会排入第二次级联。

这种情况常见于孙会话归档失败(unavailable 或 timeout)后仍保留在侧边栏中。ask 模式下,用户会再次看到归档对话框;always 模式下,会重试该孙会话并再次报告失败。第 83 行的注释要求这些通知不再触发级联,当前实现没有满足这一约束。

建议在轮询确认后记录该子会话,并吸收其后到的通知,直到通知到达或超时。

Esc 或关闭对话框时不应保存“记住我的选择”。

close 和 cancel 都会调用 finish(false)。finish 会读取 checkbox.checked。触发条件是:用户勾选“记住我的选择”后,按 Esc 或点击遮罩关闭对话框。此时 cascade 会执行 setMode("never"),之后所有父 Thread 都不再归档子 Thread。

关闭对话框表示用户放弃本次选择。用户没有确认要永久选择“从不归档”。文档只说明 Esc 等同“仅归档父会话”,没有说明它会保存设置。建议在关闭对话框时返回 remember: false。

The expand/collapse toggle was an in-flow flex item at the start of the
title trigger, so a parent row's icon and title shifted right by the
toggle width plus the row gap. Parents no longer lined up with sibling
rows at the same depth, and their children appeared left of the parent's
icon instead of one indent level to the right.

Position the toggle absolutely with a negative start margin so it sits in
the leading padding left of the icon without taking inline space. With no
insets, it keeps its static position and stays vertically aligned with
the icon. Siblings now align regardless of having a toggle, and children
indent exactly 14px relative to their parent's icon.

# codexhost 代码审查

## 阻断项

1. **边界违规**:Rust 持有了 Host 协议或 Harness 语义;`shared-contracts` 依赖其他包或引入非浏览器安全代码;`renderer-extension` 引入 Node 内置、Electron 私有 API 或 Harness SDK;Harness 专有协议泄漏出对应 Adapter;Host Runtime 直接 import 具体 Adapter 而非走插件公共契约;跨包依赖绕过公共导出。边界检查器只覆盖其中一部分,先读它实际检查什么。

避免普通刷新反复重置关系查询的重试预算

Composer 挂载和 ownership 加载结束都会调用 refresh()。如果这些调用发生在不同扫描帧,且无父关系查询已完成,每次刷新都会重新查询这些 Thread,并为它们重新安排最多三次重试。

这会重复产生批量请求。限制普通刷新触发的重试,同时保留对延迟写入的委派关系和 Host 或客户端变化的重新查询。

合并共享 Thread 的父子关系。

共享 Thread 的 Fork 子 Thread 会被返回为 parent: null。即使父子 Thread 都显示在侧边栏,子 Thread 也不会进入父 Thread 的树或归档后代列表。

请通过共享 Host 的 codexhost/thread/relation/list 查询共享 Thread 的关系,并与本地结果合并。
