    "unit_of_observation": "Varies by file: selected model/profile, product family/design, attributed claim, seller listing, hypothetical calculation or weather-station normal.",
    "model_census": "117 = 103 Durable catalog records + 10 Vestil model rows + 4 Blue Giant model rows, from three manufacturers.",
    "projection_count": "14 distinct numeric projection/thickness values in the 117-row census; 17 values in the wider family reference. Neither count establishes industry prevalence.",
    "source_scope": "Original manufacturer documentation, official government data/rules and original publishers for their own statements. Historical and inaccessible-live-page limitations remain in record notes.",
    "not_measured": "No purchases, installations, impact tests, load–deflection curves, lifespan measurements or representative installed-base sampling.",
    "geometry": "Hypothetical effective horizontal reaches, not nominal lip lengths; zero floor setback; no asserted universal ANSI minimum or compliance conclusion.",
    "physics": "Exact unit conversions; specified mass and speed; E=mv²/2; displacement-averaged force E/d under the stated energy allocation assumption."
  },
  "verification_definitions": {
    "star": "Direct source text checked; not independent product testing or confirmation of current availability.",
    "attributed_claim": "Verified that the original publisher stated the claim, not that the performance was established.",
    "historical_indexed": "Original publisher text was retrievable in the search index, while the direct article URL redirected.",
    "blank": "Not established, not zero."
