    {
      "stage": "pre",
      "question": "What distinguishes an execution plan from a to-do list?",
      "options": ["A model recommendation", "A fixed number of steps", "More prose", "A dependency graph with evidence and proof"],
      "correct": 3,
      "explanation": "Dependencies, receipts, and completion proof make the plan executable and resumable."
    },
    {
      "stage": "check",
      "question": "Why define a shared contract before its implementations?",
      "options": ["To avoid documentation", "To delay all work", "So dependent surfaces do not invent conflicting behavior", "So only one agent can work"],
      "correct": 2,
      "explanation": "A fixed contract unblocks safe parallel work on dependent surfaces."
    },
    {
      "stage": "check",
      "question": "What does a dependency cycle usually reveal?",
      "options": ["Good parallelism", "A hidden unresolved decision or bad decomposition", "Fast execution", "Strong evidence"],
      "correct": 1,
      "explanation": "Cyclic work items cannot establish a valid starting point."
    },
    {
      "stage": "check",
      "question": "When can two work items share an execution wave?",
      "options": ["When their dependencies are complete and they are otherwise independent", "When they touch the same files", "When neither has proof", "When both are important"],
      "correct": 0,
      "explanation": "A wave contains all currently unblocked independent work."
    },
    {
      "stage": "post",
      "question": "Why attach evidence to each work item?",
      "options": ["To show why the change belongs and let new evidence revise it", "To replace tests", "To decorate the plan", "To satisfy a token target"],
      "correct": 0,
      "explanation": "Evidence must justify and be capable of changing the plan."
    },
    {
      "stage": "post",
      "question": "What makes a plan resumable?",
      "options": ["One worker for everything", "A long initial prompt", "Small items with status, artifacts, dependencies, and proof", "Chat history"],
      "correct": 2,
      "explanation": "Durable item state lets another session continue without rediscovery."
