Closes #1462

Why the change

修复 /resume 首屏等待完整历史扫描的问题,让 Claude、Codex 和 DSH 优先按当前 cwd 的原生范围显示会话,再补齐其他项目。

Special things to note

  • Claude 的首批与完整查询都沿用 SDK 默认项目范围,包含同仓库 Git worktree;Codex 的原生 cwd 过滤为精确匹配,界面仍按会话自身 cwd 分组。Claude 首批最多 32 条,短页也必须继续 unlimited 读取,只有完整成功结果才进入缓存与磁盘快照。
  • Codex 的状态 DB 首批可能带旧标题或已缺少 rollout 的记录:分页进度保留已发布 ID,并用扫描结果更新元数据,最终结果才删除未确认的记录;DB 不可用、为空或查询超过 1 秒时回退。DSH 仍需枚举全部会话头;本次优化不保证完整扫描总耗时下降。
  • 未跑真实终端的 inline/fullscreen/窄屏手动流程、真实模型回合或 ChatGPT 登录。本机扩展组的 verify-claude-executable.ts 与 verify-keymap 环境隔离失败已在独立 main(3961b3c9)复现,详见验证记录。

Change outline

沿用 channel 的当前 cwd → 全项目路由,在后端目录和 DSH 元数据层提前发布进度。

- Claude: 当前项目 SDK 整表读取 → 全项目整表读取
+ Claude: SDK 默认 cwd 项目范围(含关联 worktree)首批最多 32 条 → unlimited 项目读取 → 全项目
- Codex: 当前 cwd 历史扫描与元数据修复 → 完整分页 → 全项目
+ Codex: 当前 cwd 状态 DB 首批最多 32 条 → 累计扫描进度 → 最终只保留扫描确认的行 → 全项目
- DSH: 全局活跃时间决定日志解析顺序,每 32 条发布进度
+ DSH: 当前 cwd 先解析,每 32 条或当前工作区完成时发布进度 → 其他工作区

  首批进度 → onPartial → 无快照的 SessionSupervisor
  完整成功结果 → cachedSessions + 持久化列表快照

真实 catalog、core channel 与 SessionSupervisor 的无头渲染:当前工作区的两条会话已显示,全项目查询仍挂起(fullscreen,80 列,截取顶部)。

Verification

本轮按 SDK 默认范围修正后实际运行:

pnpm build                                                     PASS:91 道门禁
node --import tsx/esm scripts/verify-claude-catalog.ts            PASS:90 checks
DSH_TUI_LANG=zh NODE_ENV=production node --import tsx/esm scripts/verify-backend-channel.ts
                                                               PASS:176 checks
DSH_TUI_LANG=zh NODE_ENV=production node --import tsx/esm scripts/verify-backend-list-snapshot.ts
                                                               PASS:47 checks
node scripts/build-guide.mjs                                   同步两份 Claude 手册
node scripts/verify-guide.mjs                                  PASS:20 份手册
真实 catalog/core/SessionSupervisor 无头渲染                    PASS:fullscreen 80 列、inline 40 列
真实 Claude SDK 本地目录查询(隔离 HOME、Git worktree、无模型)  PASS:catalog 首批及完整结果均与 SDK 原生查询一致
git diff --check                                               PASS

worktree 回归在覆盖 includeWorktrees: false 的旧实现上先失败,修正后通过;还覆盖当前 cwd 没有会话、只有 sibling worktree 会话时,在完整扫描结束前就发布这些会话,以及空首批和全项目读取失败时的完整项目回退。真实 SDK 样本含当前目录 2 条旧会话、关联 worktree 40 条新会话,默认首批是 32 条 worktree 会话,完整结果保留全部 42 条。

此前已运行的验证:

  • verify-codex-catalog-history.ts:37 checks;覆盖首批 ID 在累计进度中保留、修复元数据覆盖旧值、最终删除 DB-only 记录。
  • verify-session-list-snapshot.mjs:47 checks;verify-session-index.mjs:67 checks;verify-session-supervisor.tsx 与 verify-reports-metadata.ts 通过。
  • pnpm verify:package:3132 文件、30 入口目标通过。
  • verify-effort-slider-ui.mjs:隔离 HOME 的普通运行和两条固定欢迎提示场景均通过全部 18 项断言;pnpm verify:fixed-window 通过。两次 CI 失败帧证明欢迎提示中的 scrollbar / 推理强度 导致旧断言误判弹窗状态,现匹配实际标题与提示行,未增加等待时长。旧脚本在固定提示下分别复现 9 项 / 1 项失败。
  • 提交 0b2e15c6 的 CI 全部 18 个 job(含 ci-gate)已通过;后续提交的 CI 以 PR checks 为准。

本机扩展验证的限制:run-ci-group.mjs session-workspace --jobs 4 为 63/64、channel-ui --jobs 4 为 184/188;手册漂移已修正,verify-compaction-progress 与 verify-activity-store 在 CI 中文环境下复查通过;verify-claude-executable.ts 仍受系统已有 /usr/bin/claude 影响,verify-keymap 的剪贴板提示断言也失败,两者均在未修改的 main worktree 复现。

Publish a bounded first page from Claude's current directory and Codex's
native state database before completing the existing catalog refresh.
Resolve DSH workspace metadata ahead of other projects and publish short
workspace batches immediately while preserving complete snapshots.

Cover partial-list ordering, snapshot safety and Codex fallback paths, and
sync the bilingual documentation and bundled guide.

📝 Summary

Summary by CodeRabbit

  • New Features
    • When no saved snapshot is available, session lists prioritize the current workspace before other workspaces.
    • Claude initially shows up to 32 recent sessions from the current directory and Git worktrees in the same repository, then loads the complete listing.
    • Codex initially shows up to 32 recent threads from the current workspace, then scans history to complete and update the list. If its state database is unavailable, it falls back to a history scan.
    • DSH displays current-workspace session details before loading other workspaces. Sessions are grouped by their own working directory.
    • Failed reads retain the last complete session snapshot.
  • Documentation
    • Updated session-loading guides to describe initial results, workspace ordering, and snapshot behavior.

Walkthrough

When no first-paint snapshot is available, Claude and Codex publish bounded initial results before completing broader listings. DSH processes current-workspace session metadata before other workspace logs. Documentation and verification scripts describe and test these flows.

Changes

Workspace-first session listing

Layer / File(s) Summary
Claude initial session results
src/backends/claude/catalog.ts, scripts/verify-claude-catalog.ts, docs/claude-backend*, guide/dsh-tui-guide/claude-backend*
Claude can publish up to 32 recent sessions from the SDK’s default project scope before the full listing completes. This scope includes same-repository Git worktrees. Tests cover partial results, full listings, and snapshot behavior.
Codex initial thread results
src/backends/codex/catalog.ts, scripts/verify-codex-catalog-history.ts, docs/codex-backend*, guide/dsh-tui-guide/codex-backend*
Codex can publish up to 32 recent state-database threads before scanning rollout files. The scan supplies the final results, and fallback cases are tested.
DSH current-workspace prioritization
src/dsh-adapter/channel/*, src/dsh-adapter/sessions/list.ts, scripts/verify-backend-list-snapshot.ts, scripts/verify-session-list-snapshot.mjs, README.md, README_ZH.md
The Channel passes its current working directory to DSH listing. DSH processes that workspace first and emits progress when its sessions are processed, while preserving the complete listing across workspaces.

Effort slider UI verification

Layer / File(s) Summary
Visible terminal row assertions
scripts/verify-effort-slider-ui.mjs
The smoke test checks English and Chinese help and slider text against visible terminal rows. Dismissal checks verify that the exact slider title row is absent.

Priority: ➖ Normal

Estimated code review effort: 3 (Moderate) | ~25 minutes

Severity of issue fixed: Medium


Merge Risk: ⚪ Minimal · up to 6600a

/resume should show current-workspace sessions sooner when no snapshot exists, while the complete listing and snapshot behavior stay the same. No merge-blocking risk is identified in the reviewed changes.

Comment thread src/backends/claude/catalog.ts Outdated
Exclude sibling worktrees only from the initial progress batch and retain
the SDK's complete project scope, including after a short or empty first
page. Keep the all-projects failure fallback from dropping sibling sessions.

Cover direct catalog reads and the real channel fallback, and sync the
bilingual documentation and bundled guide.
Keep Codex's initial state-database IDs in every progress batch until the
complete rollout result resolves, while allowing repaired metadata to win.
Always perform Claude's unlimited listing before publishing a complete
result, including when the bounded first page is short.

Cover cumulative progress, metadata repair and authoritative memory/disk
snapshots with focused catalog regressions.

unlimited read. Treat the bounded read as optional: catch its failure, call
`onPartial` only when it succeeds, and preserve the unlimited listing as the

Observe the same rendered Help heading for open and close waits, and match standalone effort titles and hint text. Random welcome tips can mention scrolling or reasoning effort and otherwise trigger premature input or false close failures.
Use the SDK default project scope for bounded progress and complete session queries. Include sibling worktrees from the first batch, retain unlimited completeness checks, and synchronize the regression coverage and bilingual documentation.
