    "Decay describes observed persistence, not the full causal mechanism behind why a citation disappears.",
    "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."

  "question": "What does the decay data say about brand resilience?",
  "directAnswer": "Rarely is brand resilience observed in AI citations. Out of 10,991 brands analyzed, only 13.2 percent qualify as very stable, with the average brand half-life sitting at 31 days.",
  "answerSummary": "Stable AI visibility is a defensible advantage precisely because it is uncommon, requiring continuous effort to combat the standard 31 day decay cycle.",

    "Separate durable wins from temporary spikes to avoid overreacting to short-lived mentions."
