v0.4.2

What a mirrored turn shows

• Each collapsed node lists the files that turn touched (✏️ wrote or edited, 📖 read) and previews the answer's conclusion instead of its opening line. The zoomed-out plaque uses the same conclusion.
• Tool attachments record their file paths and what they did. A Write keeps its whole file and an Edit its diff; reads still clip.
• A subagent's report (task notification) folds into the turn that launched it instead of appearing as a question, including when it arrives after that turn was mirrored.

Session Atlas

• Claude Code subagent files are recognized as sub-threads: hidden by default, shown by the toggle, and each opens as its own mirror under its own id. They no longer wear the parent session's badges or fail to open.
• /thoughtdag works again on sessions that spawned subagents: the deep link matches the session file by name.

Links and local paths

• Links in answers never navigate the app away. Web URLs open in the system browser.
• A local path opens on this machine: a folder or plain file in Finder, an image or PDF in its viewer. Nothing executable is launched.
• Images an agent produced render inline; relative paths resolve against the session's working directory.

镜像轮次的呈现

• 折叠节点列出这一轮碰过的文件（✏️ 写或改，📖 读），预览显示回答的结论段而不是开头一句；缩小后的牌子用同一段结论。
• 工具附件记录文件路径和动作。Write 保留整个文件，Edit 保留差异；Read 仍然裁剪。
• 子 agent 的报告（任务通知）折进派出它的那一轮，不再变成一条提问；晚于镜像到达的也会补进去。

Agent 对话地图

• Claude Code 的子 agent 文件识别为子线程：默认隐藏，开关可见，每个以自己的 id 作为独立镜像打开，不再顶着父会话的徽章、也不再打不开。
• /thoughtdag 在派过子 agent 的会话上恢复正常：深链按文件名匹配会话文件。

链接与本机路径

• 回答里的链接不会让应用跳走；网址交给系统浏览器。
• 本机路径在本机打开：目录或普通文件在 Finder 中定位，图片和 PDF 用系统查看器打开；不会启动任何可执行文件。
• agent 产出的图片直接内联显示；相对路径按会话的工作目录解析。
