    "Brand- and domain-level averages can hide very different retention patterns by query class or model.",
    "Some of the stickiest or most volatile domains come from niche query pockets and should be read as examples, not universal leaders."

  "directAnswer": "Yes. Among the 108,650 distinct citation URLs tracked longitudinally, 72.8% appear once and vanish.",
