  "verification": "verified",
  "calculation": "Read from the market-share competitor column that the segment's competitor mapping resolves to your own domain, filtered to the segment, the medium, the date range and your canonical site URL. If the client row cannot be resolved, the leg is null and the response says so.",

  "questions": [
    "What is the organic half of our total search share?"
  ],
  "interpretation": "Your organic standing inside a tracked segment, expressed on a 0 to 100 scale, before the paid leg is folded in. It is directional: absolute share levels are approximations by construction, and the gap to the leader is the more reliable read than the level itself.",
  "caveats": [
    "Always CTR-modeled search market share of tracked demand, directional, scoped to the keywords in a tracked segment, and never revenue share.",
    "Stored 0 to 100 while the paid leg is stored 0 to 1; the two are normalised by name before being combined.",
    "Requires a competitor mapping that identifies your own row for the segment and medium; without it the leg is null.",
    "A segment that does not track a competitor cannot see them, so absence from the standings means untracked, not absent.",
    "It ships beside the paid leg under a camel-case payload key the shared format contract cannot classify, so it renders as a bare number with no percent sign and no scale correction."
