+ * dispatcher-stuck-planning.test.ts — #3656

+ * Verify that state.ts contains the disk-to-DB task reconciliation logic
+ * that prevents the dispatcher from getting stuck in an infinite planning
+ * loop when the planner writes a PLAN.md but never calls the persistence
+ * tool, leaving the DB with zero task rows.
