The five grades are summed and the total is read against five named bands. This file is the definition of the instrument. It carries no scores, because none have been recorded.",

    { "band": "Emerging", "range": "6-10", "meaning": "One or two platforms surface the entity, usually as one candidate among several." },
    { "band": "Recognised", "range": "11-15", "meaning": "A majority of platforms name the entity, though not always as a direct answer." },
    { "band": "Dominant", "range": "16-20", "meaning": "Most platforms answer with the entity directly; the remainder cite supporting sources." },
    { "band": "Definitive", "range": "21-25", "meaning": "Nearly every platform states the full relationship in its own generated answer." }

  "rules": [
    "One score per platform per window. If several prompts are run, the platform takes its highest evidenced grade.",
    "Evidence or nothing. A grade without a dated capture is not recorded, and the platform stays in the awaiting state.",
    "Zero is a real score. A platform that declines to name anyone is graded 0 and that 0 is published.",
    "Awaiting is not zero. An untested platform contributes no score at all, and no total is published while any platform is untested.",
    "No back-filling. A grade is recorded against the date it was observed, never applied retroactively to earlier weeks.",
    "Downgrades are published like upgrades. If a platform stops naming the entity, the score falls and the fall is logged."
  ],
  "limitations": [
    "The total is a sum, not a weighted model. A platform with a large audience counts the same as one with a small audience.",
    "The same total can be reached by very different distributions, so the five components are always published with the total.",
    "The instrument measures what a system said on a date to one observer. It does not measure what it will say to anyone else."
