  "submittedPrompt": "Map total forest area in square kilometers by region.\n\nTask conventions: Use the frozen country polygons and World Bank AG.LND.FRST.K2 2021 column, in km². Use the published World Bank regional aggregates already present in the frozen table, not individual country values or a mean/sum computed from countries. Join original country geometry REGION_WB to table Country Name exactly. This selects the seven published all-income regional aggregates; Antarctica has no corresponding value and remains unknown. Nonmatching identifiers and missing measurements remain unknown; do not guess them or substitute another year. Retain every original country feature and benchmark_row_id, including unknowns. No data must have a distinct map category, not zero. Create a quantitative choropleth with five quantile classes (fewer only if tied values collapse breaks), a visible legend with numeric bounds and units, and a neutral No data category. Values equal to a class break enter the upper class. Preserve negative and genuine zero values. This fixed classification and year are disclosed evaluation conventions; do not retrieve live replacements. The reporting regions are the supplied World Bank REGION_WB groups. Every original country polygon carries its region’s published value; retain original boundaries and IDs rather than inventing regional geometry. This does not mean the country itself has that value. The five-quantile display classification operates on those original feature rows, so its breaks reflect repeated regional values; this is only a display convention, not population weighting or recomputation of the regional statistic. Label the map and answer as regional aggregates.\n\n\n\nAdd the resulting quantitative country layer to the map and retain an inspectable data artifact containing the original country geometry, benchmark_row_id, numeric value and class. End with one fenced JSON object: {count: countries with a known numeric value, unknown_count: countries without one, coverage_note: string, selection: {collectionId, itemId, assetKey}, value_field: numeric_column_name, class_field: classification_column_name, map_layer_id: delivered_layer_id}. The artifact must include known AND unknown countries, not only the known subset. Explain the year, units, key limitations and legend in the final response.\n\nDelivery format: provide the answer object with all fields specified above as final_response on assess_result, alongside the inspected final artifact_refs. This replaces the JSON-code-block formatting requirement above. Blue attaches your explicit selection to the accepted final answer. Finish with a concise ordinary-language answer agreeing with that selected result; do not duplicate the JSON in chat.\n\nSupplied immutable inputs:\n[\n  {\n    \"name\": \"World Bank country boundaries\",\n    \"edition\": \"GeoBenchX harmonized names\",\n    \"units\": {},\n    \"collectionId\": \"blue-generated--[resource id withheld]\",\n    \"itemId\": \"[resource id withheld]\",\n    \"assetKey\": \"data\"\n  },\n  {\n    \"name\": \"World Bank AG.LND.FRST.K2\",\n    \"edition\": \"Frozen GeoBenchX World Development Indicators; use 2021\",\n    \"units\": {\n      \"2021\": \"km\\u00b2\"\n    },\n    \"collectionId\": \"blue-generated--[resource id withheld]\",\n    \"itemId\": \"[resource id withheld]\",\n    \"assetKey\": \"data\"\n  }\n]",
  "finalAnswer": "Added to the map: the 2021 World Bank regional forest-area aggregates, in km², carried on the original country polygons.\n\nIt keeps all 251 country features. 250 have a known regional value. Antarctica is a neutral No data category.\n\nImportant limitation: this is a regional aggregate map repeated across country polygons, not country-level forest area.\n\nLegend: tied regional values collapsed the requested 5 quantiles to 4 actual classes, plus No data. Break values go into the upper class. The displayed ranges are 230,408.466–<6,231,790.779; 6,231,790.779–<6,648,558.5; 6,648,558.5–<9,295,696.966; and 9,295,696.966–10,576,123.193 km².\n\nSources: Benchmark fixture · World Bank country boundaries and Benchmark fixture · World Bank AG.LND.FRST.K2 (provider Blue; source revision not stated; retrieved 2026-10-07).\n\n### Limitations\n\n- This map shows published World Bank regional aggregates repeated across member country polygons. It does not show country-level forest area.\n- Repeated regional values collapse the requested five quantiles to four actual legend classes.\n- Antarctica has no matching published regional value in the supplied frozen table and remains No data.\n- This map shows published World Bank regional aggregates repeated across country polygons; it does not show country-level forest area.\n- Repeated regional values collapsed the requested five quantiles to four actual legend classes.\n- Antarctica has no matching published regional value in the frozen table and remains No data.",
