  "unit": "percent of that prompt's weighted voice",
  "direction": "higher-better",
  "verification": "verified",
  "calculation": "(1.25 × your citations for the prompt + your mentions for the prompt) ÷ (1.25 × all domains' citations for the prompt + all brands' mentions for the prompt) × 100, returned empty when the prompt drew no weighted voice at all.",
  "numerator": "Your weighted voice on the prompt, citations at 1.25, mentions at 1.",
  "denominator": "The same weighted combination across every cited domain and named brand on that prompt.",
  "aggregation": "Each prompt carries its own denominator, so these do not average into an account-level share and do not sum to a hundred down the column.",

  "interpretation": "A competitive standing on one prompt, comparable in kind to the citation and mention shares beside it. Because it folds two behaviours together under fixed weights, a move is a prompt to read the citation and mention columns rather than a finding on its own.",
  "caveats": [
    "The 1.25 and 1.0 weights are a product decision, not a quantity any engine reports. They match the semantic layer's own presence score, so the prompt figure and the account figure weight the same way.",
    "When the all-domain legs return no rows for a prompt, both sides of the ratio fall back to your own totals and the share reads as one hundred percent. On a thin prompt, check the prompt's citation and mention totals before reading it as dominance.",
    "The same column label appears on the competitor, intent, geography and brand tabs carrying a semantic-layer measure computed over the whole slice rather than per prompt. Same weights, different population.",
    "The prompt tab reads the market-share rank and brand-mention datasets. If the tracker has no market-share segment for the requested engine the tab returns no rows with a stated reason.",
    "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."
