  "question": "How does checkpoint performance change when error observability, evidence access, reviewer capacity, and stop authority vary independently?",
  "baseline": "A nominal approval step fails whenever the relevant error is invisible, the evidence is withheld, review capacity is absent, or the reviewer cannot stop release.",
  "protocol": [
    "Freeze one hundred twenty cases crossing four binary control conditions.",
    "Count an error as stopped only when all four necessary conditions are present.",
    "Report the model as a logical stress test rather than an estimate of human accuracy."

    "The conjunctive model is deliberately severe and contains no probability of partial detection, reviewer learning, or organizational workarounds."
