  "steps": [
    [
      "Confirm scope and configuration",
      "Use the inert CV-101 training fixture, model MIN-CV101-MP2 and revision A DRAFT. No real equipment operation is authorized."

    [
      "Review the required evidence",
      "The exercise requires separate observations of upper CAM_A / KEEPER_A and lower CAM_B / KEEPER_B."

      "Establish the closed-view context",
      "Select the assembled inspection view. Locate CG101 and the left hinge; do not treat closure as proof of retention."

    [
      "Inspect upper point A",
      "Locate the captive cam tongue against fixed KEEPER_A. Record the observed engagement state."

      "Inspect lower point B",
      "Inspect CAM_B against fixed KEEPER_B independently. Do not infer B from A."
    ],
    [
      "Introduce the discrepancy",
      "Select Lower B disengaged. The guard remains closed while the lower tongue turns away from its retaining position."
    ],
    [
      "Choose HOLD",
      "State that lower B is unresolved. A continue or ready decision fails this critical training criterion."
    ],
    [
      "Request simulated supervisor review",
      "Explain which retaining point is unresolved and the evidence observed. Do not attempt to open an engaged guard."
    ],
    [
      "Rehearse supervised correction",
      "After simulated reviewer approval, compare the corrected assembled view. The correction returns B to its keeper with the guard closed."
    ],
    [
      "Recheck both points",
      "Inspect A and B again. A correction does not silently clear the hold or complete the evidence."

      "Capture the result",
      "Record asset, model/procedure revision, before/after observations, decision, reviewer and remaining questions."
    ],
    [
      "Complete training review",
      "A training reviewer evaluates the evidence. Any real work release remains a separate decision under the equipment owner's approved procedure."
