    "No numbers or identifiers appear in the questions; expected records are hot body-only facts with generic card titles/summaries.",
    "The anchor-free rescue only runs when no card field shares a meaningful query term, and scans at most 240 hot bodies.",
    "Cold anchor-free facts still rely on abstract FTS/card summaries; this run covers the hot tier.",
    "n=3 probes, one model; mechanism/data point, not statistical evidence."
