dsh-session-tree is a lightweight community plugin for DeepSeek Harness (DSH) (v0.2.0-beta.1, MIT license) designed to provide a read-only session lineage view. By reading the native SessionSummary.parentId lineage data from DSH, the plugin enables users to easily switch between parent sessions, sibling branches, and child sessions without maintaining an independent database or modifying native Sessions or parent pointers. After installation, a new "Branches" tab appears in the Chat interface, allowing users to navigate to the corresponding Session by clicking on tree nodes. The plugin is compatible with DSH 0.1.0-rc.7 and Node.js 22.19+/24.0+ environments and requires installation via `dsh plug`.
