  "description": "Frozen before observing retrieval scores. Independently agent-authored relevance judgments for the original 40 seed cards: 24 answerable cases, 6 unsupported cases, and 4 diagnostic challenge cases. Answerable cases mix literal wording with meaning-preserving paraphrases across all 14 categories. Relevant IDs identify individual prompt meanings, not every card sharing a category. Challenge cases are reported separately from answerable quality metrics; an empty relevance set means no clear supported interpretation. Do not tune this fixture to retrieval outcomes. Authorship metadata was corrected after the first run; all queries and relevance labels remain unchanged.",
