  "question": "Create heatmap of TB cases in states with available data.",
  "submittedPrompt": "Create heatmap of TB cases in states with available data.\n\nTask conventions: Use only the frozen 2023 county TB tables for these states: {\"25\": \"tb_ma\", \"36\": \"tb_ny\"}. Select original Census county features by STATEFP before joining NAME to the corresponding table's County column. Use tb_ny '2023 cases' and tb_ma 'Number of Cases', not rates. Repeated county names across states must not mix; aggregate state/city totals and footnotes are not counties. Preserve genuine zero cases. Missing counts are unknown, never zero. Derive one geometric centroid per original county in EPSG:5070 and weight it by the published county case count. This represents county totals at geometric centroids, not patient locations or within-county disease density. No population-weighted centroid is claimed. Use a disclosed metric raster adaptation instead of the reference's screen-pixel radius: grid={\"bounds\": [-500000, 1000000, 3000000, 3500000], \"crs\": \"EPSG:5070\", \"resolutionX\": 5000, \"resolutionY\": 5000}, Gaussian radiusM=50000 is three sigma, kernel truncated at four sigma with constant-zero padding. Use weightField='case_count' and weightUnit='cases'. A cell measures smoothed case-count mass per cell, not cases/km². Preserve complete grid including zero cells; no normalization, resampling or extra clipping. The two-state task corrects the archived reference's joining of tables by county name without state disambiguation; no cases may be counted twice.\n\n\n\nAdd the heatmap and publish both its raster and an inspectable original-county polygon selection carrying case_count and benchmark_row_id. End with one fenced JSON: {count: number of counties with known counts, unknown_count: counties with unknown counts, coverage_note, selection:{collectionId,itemId,assetKey} for original county polygons with known counts, value_field:'case_count', density:{collectionId,itemId,assetKey} for the raster, map_layer_id: actual heatmap layer ID}. Clearly disclose centroid aggregation and frozen year.\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\": \"US county boundaries\",\n    \"edition\": \"Census TIGER/Line 2024\",\n    \"units\": {},\n    \"collectionId\": \"blue-generated--[resource id withheld]\",\n    \"itemId\": \"[resource id withheld]\",\n    \"assetKey\": \"data\"\n  },\n  {\n    \"name\": \"Massachusetts county tuberculosis cases and published rates, 2023\",\n    \"edition\": \"Massachusetts DPH 2023 summary, frozen GeoBenchX transcription\",\n    \"units\": {\n      \"Number of Cases\": \"cases\",\n      \"TB Case Rate[1] 2023(cases per 100,000)\": \"cases per 100,000 people\"\n    },\n    \"collectionId\": \"blue-generated--[resource id withheld]\",\n    \"itemId\": \"[resource id withheld]\",\n    \"assetKey\": \"data\"\n  },\n  {\n    \"name\": \"New York county tuberculosis cases and rates, 2019\\u20132023\",\n    \"edition\": \"NYSDOH 2024 report, frozen GeoBenchX transcription; use 2023 counts\",\n    \"units\": {\n      \"2023 cases\": \"cases\",\n      \"2023 cases per 100 000\": \"cases per 100,000 people\"\n    },\n    \"collectionId\": \"blue-generated--[resource id withheld]\",\n    \"itemId\": \"[resource id withheld]\",\n    \"assetKey\": \"data\"\n  }\n]",
  "finalAnswer": "Done — the frozen 2023 MA/NY TB heatmap is on the map, and the county selection with `case_count` and `benchmark_row_id` is published. It covers 76 counties with known counts and 0 unknown county counts in this two-state task.\n\nImportant limit: this heatmap smooths county totals from geometric county centroids, so it does not show patient locations or within-county disease density.\n\nNext: open the county layer to inspect county values, or use the heatmap layer for regional review.\n\n### Limitations\n\n- The heatmap represents county totals at geometric centroids, not patient locations, within-county disease density, or population-weighted centres.\n- Only Massachusetts and New York are included because those are the supplied frozen county TB tables for this task.\n- County totals are shown at geometric centroids, not patient locations, within-county disease density, or population-weighted centres.\n- The raster unit is smoothed case-count mass per 5 km cell, not cases per square kilometre.\n- Coverage is limited to the supplied frozen 2023 Massachusetts and New York county TB tables.",
