  "question": "Calculate the percentage of Angola's population living within 20km of mineral extraction facilities",
  "submittedPrompt": "Calculate the percentage of Angola's population living within 20km of mineral extraction facilities\n\nTask conventions: Use the frozen WorldPop 2020 UN-adjusted population-count raster, original band 1 and grid; values are people per cell. Use the supplied facilities records with Country exactly 'Angola'. Do not invent missing facilities or include another country. A valid population cell qualifies when its centre is at most 20000 metres from its nearest selected original Point, using shortest WGS84 ellipsoid surface distance. This frozen centre-distance convention avoids overlapping-buffer double counts and projected-map scale ambiguity. It is not road travel distance or within-cell population positioning. Sum original counts in qualifying cells, divide by all original valid country-raster counts and multiply by 100. No resampling, constant-cell-area conversion or invented census denominator. Zero population stays valid; NoData is unknown. Count each cell once. The result describes the supplied facility inventory and raster coverage, not proof that every facility is recorded. Retain the full-grid distance raster and selected-population raster (original count when eligible, zero otherwise, original missing-data mask).\n\n\n\nCompute the percentage and publish both inspectable rasters. A map is optional. End with a fenced JSON object: {count: qualifying cell count, unknown_count: original masked/nonfinite cell count, coverage_note, selection:{collectionId,itemId,assetKey}, distance:{collectionId,itemId,assetKey}, metrics:{selected_people:number,total_people:number,percentage:number}}. Label selected population as people per cell and distance as metres. Report the historical year and coverage limitations. Do not round machine-readable metrics to integers.\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\": \"Angola population count, WorldPop 2020\",\n    \"edition\": \"2020 UN-adjusted population aggregated to 1 km cells\",\n    \"units\": {\n      \"band1\": \"people per cell\"\n    },\n    \"collectionId\": \"blue-generated--[resource id withheld]\",\n    \"itemId\": \"[resource id withheld]\",\n    \"assetKey\": \"data\"\n  },\n  {\n    \"name\": \"African mineral extraction facilities\",\n    \"edition\": \"USGS 2021 benchmark snapshot\",\n    \"units\": {},\n    \"collectionId\": \"blue-generated--[resource id withheld]\",\n    \"itemId\": \"[resource id withheld]\",\n    \"assetKey\": \"data\"\n  }\n]",
  "finalAnswer": "About 43.02% of the population in the supplied Angola WorldPop 2020 raster lives within 20 km of a supplied Angola mineral extraction facility. That is 14,137,536.462 people out of 32,866,268.004 valid people-per-cell counts; 21,584 cells qualify. The Angola filter kept 53 supplied records, which collapse to 49 unique point locations because four coordinate pairs are duplicates.\n\nLimits: this uses the supplied WorldPop 2020 raster and supplied USGS 2021 facility snapshot. 947,409 masked raster cells remain unknown, and the result describes the supplied raster coverage and inventory only.\n\nNext: I can add the published selected-population raster and distance raster to the map if you want.\n\n### Limitations\n\n- Population values are from the supplied WorldPop 2020 UN-adjusted 1 km raster; masked or nonfinite cells are excluded as unknown.\n- Facilities are from the supplied USGS 2021 benchmark snapshot; the result reflects this supplied inventory only and does not prove all facilities are recorded.\n- Distance uses original raster cell centres and shortest WGS84 ellipsoid surface distance to the nearest selected point; it is not road distance or travel time.\n- Population values come from the supplied WorldPop 2020 UN-adjusted 1 km raster; 947409 masked cells are unknown and excluded from totals.\n- Facilities come from the supplied USGS 2021 snapshot; the result reflects this supplied inventory only and does not prove that every Angola facility is recorded.\n- Distance is original raster cell-centre WGS84 ellipsoid distance to the nearest selected point, not road travel distance or within-cell population location.",
