dsh-session-git

DeepSeek Harness lets you branch only at the latest completed turn, and the official sidebar stays flat by design. When you want to go back to an earlier finished turn and open a child line from that exact point, existing tools either rewind workspace files or cut only at the tail, leaving a gap for clean turn-level historical forking.

dsh-session-git fills that gap: a header picker lists every completed turn in the loaded window, and selecting any one forks a child session at that precise seq. The child shows a read-only parent chip and a family-tree popover you can walk back through. The source session is never archived, cancelled, or touched on disk; overlapping forks on the same source are refused with a clear error. The latest turn keeps the official Branch control, and the plugin registers at priority 50 so official produced-files stay in the chain.

It suits Harness Web users who frequently explore parallel conversation paths, want to A-B compare a specific decision, or need a clean branch point without side effects. If you need a disk-level time machine or file rollback, this is not that plugin; it stays strictly at the conversation level.
