DSH 撤销/回退系统：配置变更自动存档，一键撤销/恢复/回退到任意版本，支持 WebUI 与离线 CLI/GUI 工具（DSH 启动失败也能救）。

Message recall (撤回) plugin for the DSH Web UI: one undo button on each user message that removes the turn and everything after it, durably, without reverting code changes.

User-side undo/redo for DeepSeek Harness (dsh): the /undo command rolls the transcript back to before the last message and /redo restores it.

Claude Code /rewind equivalent for DeepSeek Harness: git-first workspace file snapshots before every mutating tool execution, turn-boundary session forks, and a one-shot /rewind command that restores files and forks the session back to a checkpoint

一键提示词增强：独立 LLM 调用把模糊草稿改写为更强的提示词，不满意可撤回。

DeepSeek Harness diagnostic, repair, and rollback plugin: dsh_doctor (diagnose), dsh_doctor_fix (journaled repair), dsh_doctor_rollback (LIFO undo), plus a Cordis runtime service for dynamic self-healing.

Hash-anchored read/edit/batch_edit/undo_last_edit tools for DeepSeek Harness (dsh). Every line gets a unique 3-char hash (A-Za-z0-9) that stays stable across edits; stale or ambiguous anchors are rejected, never fuzzy-matched. Undo persists across restart
