 # 设计方案：Ctrl+O 行为重构 —— 对齐 Claude Code 的 Transcript 模型
 
+> **⚠️ 已被取代（superseded）**：本文档记录的 **`TranscriptView` + `AlternateScreen` 全详情冻结快照屏** 方案已在后续重构（PR #8077）中**移除**。当前实现中，`Ctrl+O`（与 `Alt+T` 共用 `Command.TOGGLE_THINKING_EXPANDED`）不再打开独立的 transcript 屏，而是**就地切换 full-detail 模式**：通过 `ThoughtExpandedContext.allExpanded` 由 `MainContent` 以 `fullDetail` 下传给每个 `HistoryItemDisplay`，在主视图内联展开所有思考块与工具组（并解除工具结果截断），再按一次收起。下文凡描述独立 transcript 屏与 alt-screen 的章节（如 §3.2、§4.2–§4.5、§9 的栈式 commit 拆分）仅作**历史记录**保留，与现行代码不符。

 # Tool-Use Summaries
 
-Qwen Code can generate a short, git-commit-subject-style label after each tool batch completes, summarizing what the batch accomplished. The label appears inline: for a completed tool group in the main view it replaces the generic `Tool × N` header; when the group is force-expanded (in the `Ctrl+O` full-detail transcript, or for error / user-initiated batches) it appears as a dim `● <label>` line below the group.

 This is a UX aid for parallel tool calls: when the model fans out into several `Read` + `Grep` + `Bash` calls at once, the summary tells you the intent at a glance instead of forcing you to scan the tool list.

 2. **No backfill on toggle or on session resume.** A `tool_group` that completed before the feature was enabled (or before you flipped the setting on, or in a resumed session — `ChatRecordingService` does not persist summary entries) will never get a label. There is no "sweep existing history" pass. If you turn this setting on mid-session, only _future_ batches will show a label; older groups keep the default rendering with no indicator that a label is missing.
 3. **Main-agent batches only.** The trigger lives in the main session's turn loop (`useGeminiStream`), so:
