Session layer of DeepSeek Harness Web GUI

Key features

• A real minimap of the session trajectory for the DeepSeek Harness Web GUI — it takes the transcript's scrollbar seat and turns it into a scaled, colored picture of the whole loaded conversation, with your own messages emphasised and clickable anchors beside it.
• Each card is tied to its anchor dot by a bezier that tracks live as the transcript scrolls
• Hover the rail — it widens and shows a preview card for the row under the cursor (kind, n/total for your own messages, and the row's text).
• The map covers the loaded window.
• unloaded prompts get a dashed border, tag and dashed string, and the message you came from is spotlighted.
