  "procedure": [
    "Choose one evidence-backed answer for each criterion.",
    "Multiply each known answer value by its criterion weight and sum signed points.",
    "Normalize signed points only across known weight so unknown answers never act as neutral evidence.",
    "Apply BUY at -30 or lower, BUILD at +30 or higher and HYBRID between those thresholds.",
    "Withhold a decision when known-weight coverage is below 75 percent or any gate-critical criterion is unknown.",
    "Show a decision-boundary warning when the index is within seven points of either outcome threshold.",
    "If a selected constraint blocks the numeric outcome, require constraint review and return HYBRID as the working architecture boundary.",
    "Compare the result with editable three-year TCO assumptions and record both artifacts together."

  "boundaries": [
    "The decision index is an authored decision-support model, not a probability, benchmark, forecast or confidence score.",
    "Thresholds are transparent editorial defaults and have not been statistically calibrated against project outcomes.",
    "TCO values are editable scenario assumptions, not Pharos pricing and not market averages.",
    "A low-cost path can still fail a mandatory data, security, legal or operating constraint.",
    "The tool does not replace architecture discovery, procurement, security review, legal advice or financial analysis."
