  "summary": "A single estimate hides how much the answer depends on being lucky about the assumption.",
  "kind": "protocol",
  "body": "Choose one material assumption and vary it across a defensible low-to-high range while holding the rest of the model fixed. Record how the value of each option changes. Repeat for the assumptions that matter most. This is a diagnostic of model sensitivity, not a forecast that every input will move independently.",

    "One-at-a-time sensitivity can miss interactions; use broader scenario or probabilistic analysis when assumptions move together."
