/**
 * The golden set for the offline eval: a fixed collection of queries, each with
 * a realistic set of candidate results, the subset of those a human would call
 * relevant, and (for the answer eval) a reference answer and a rubric.
 *
 * This is deliberately hand-curated and stable. It is a regression baseline,
 * not a benchmark: the point is that a change to the reranker, the prompt, or
 * the model moves these numbers in a direction a human can read, not that the
 * numbers are absolute.
 *
 * To grow the set, add an entry with the same shape. Keep the relevant labels
 * unambiguous (a result is clearly about the query or clearly not) so the
 * metric does not depend on a borderline call.
 *
 * Retrieval constraint: the input top-3 (the `results` array order) must not
 * already hold every relevant result it can fit. If it does, a no-op reranker
 * (which preserves input order) scores that entry as well as a working one,
 * and the retrieval eval's floors stop being falsifiable. The per-entry
 * validator and the "stays falsifiable" aggregate in goldenSet.test.ts pin
 * this; re-tune the floors in thresholds.ts if the set changes substantially.
