DSH Retrace

Key features

• Detect → repair → guardA watchdog snapshots the log at the first sign of concurrent writes
• Recallhover any assistant reply, or the row under any user message: Removes the whole exchange round (the input and the agent's output, tool rows included) from both the model context and the conversation view
• Recall · Edit-and-resend · Regenerate, plus write-safe in-conversation versioning — the Agent business layer (production-grade guarantees) for DeepSeek Harness.
• a user-actions conversation node under every user message (an edit/recall row with an inline editor)
• offline fix neutralizes problem markers and clips cross-step references in place
