  "title": "Use regret as a cross-scenario lens, not prophecy",
  "summary": "Regret compares an option with what would have been best in each scenario.",
  "kind": "protocol",
  "body": "For each plausible future, estimate how much worse each strategy performs than the best option for that future. Use the pattern to discuss trade-offs, not as a magic single score.",
  "limits": [
    "Scenarios and robust-decision tools organize uncertainty; they do not predict the future. Preserve governance, evidence and explicit review triggers."

    {
      "claim": "Robust Decision Making uses exploratory analysis to stress-test strategies over many plausible futures and seek strategies that perform acceptably across uncertainty rather than optimizing a single prediction.",

      "role": "supports",
      "note": "Full RDM can require substantial modeling; lightweight cards should not claim equivalent rigor.",
      "locator": "Abstract and method overview"
    }

  "use_when": [
    "When decision makers care more about avoiding a disastrous miss than maximizing one forecasted payoff."

  "avoid_when": [
    "Scenarios and robust-decision tools organize uncertainty; they do not predict the future. Preserve governance, evidence and explicit review triggers."
  ],
  "example": "One vendor choice wins the base case but has extreme regret if data residency rules tighten; a hybrid option has smaller regret across all cases.",
  "check": "The decision discussion sees where each strategy would be painful in hindsight without claiming those futures are forecast probabilities.",
  "steps": [
    "Define plausible futures.",
    "Estimate outcome by strategy and future.",
    "Compute or qualitatively rank regret within each future.",
    "Discuss severe and persistent regret regions."
