  "caveats": [
    "Two differently named semantic-layer fields feed this one output key depending on which source a verb reads. They compute the same ratio, so a grid figure and a drilldown figure are the same measure under two names, but the names differ in exports and in the app.",
    "The denominator is the tracked competitor set, not every brand an engine could name.",
    "Being named in an answer says nothing about being described correctly, that is the sentiment read, and canon flags the Represented rung as only partly instrumented.",
    "Every figure is scoped to a tracked prompt basket, a sample, not a census, so the basket's coverage belongs beside the number it produced.",
    "Engines are non-deterministic: the same prompt can answer differently twice, which is why this is reported as a rate over repeated observation rather than as a state."
