dsh-fork-graph

After a day of forking DSH sessions, the sidebar shows only a flat, indented list: it tells you what exists but not what came from what. dsh-fork-graph renders the lineage as a git-style graph in the session header. Each branch gets its own coloured lane, forks leave the parent node as a curve, and every row carries the facts that matter (current, running, subagent, fork count). Clicking any node jumps you to that session.

The plugin is a pure read-only projection: no writes, no second source of truth, no extra global type surface. By default it shows only the current session family, and when there is no fork in that lineage the control simply does not render.

It is built for heavy DSH users who fork sessions to test risky changes, dispatch subagents to audit files, or repurpose a dead end as a new starting point, and who need to locate the session where it still worked without scrolling through a wall of indentation.
