  "disposition": "Stratified appendix for the existing shared Europe reading pilot; no new study count or slug",
  "question": "Does the Portugal female-minus-male descriptive difference change between any-book reading and10+ books among readers within compatible age/education strata?",
  "geographies": ["PT", "ES", "EU27_2020"],

  "scope": "All published age by education strata,2022; strata overlap and must never be summed or treated as an independent sample of people",
  "method": "For each sex, require allfour source categories numeric and sum100 within0.2percentagepoints. Reach=sumLT5+5-9+GE10. Conditional10+ =100*GE10/reach only if reach positive. Calculate F minus M for each metric only if both sexes pass. Preserve raw cellindices, values and flags. Any nonempty source flag retained and excluded from primary unflagged comparison, while numerically computable flagged rows remain separately marked.",
  "uncertainty": "Differences are descriptive point estimates from rounded survey percentages, not formaltests. No joint uncertainty, age-adjusted overall, microdata reconstruction or causal claims. Display1decimal and retain exact calculations in CSV.",
  "rights": "Use shared producer copyright/dictionary/module evidence. No new source requests.",
  "handoff": "Send actual coverage and results to global owner for substantive integration and independentQA; aggregate pilot alone did not answer original question."
