{"answer":"Recommended action: Fix the graph (connect steps, make terminal events StopEvent/InputRequiredEvent subclasses), or opt out per workflow with Workflow(skip_graph_checks={'reachability','terminal_event','dead_end'}) or per step via the step decorator's skip_graph_checks for intentional patterns.\n\nOption: Repair the graph or use skip_graph_checks for intentional topologies [evidence: official_recommended_action]\nApplies when: llama-index-workflows >=2.17\nSteps:\n1. Read each [check] line in the error\n2. Connect or remove unreachable/dead-end steps; subclass StopEvent/InputRequiredEvent for events meant to leave the workflow\n3.
