  "question": "List and make a map of all counties that touch or include the Mississippi River",
  "submittedPrompt": "List and make a map of all counties that touch or include the Mississippi River\n\nTask conventions: Use the original CEC 2023 river geometries where NameEn equals 'Mississippi River', not tributaries or similarly named rivers. Select original 2024 county polygons intersecting any selected river line, including boundary touches. Compare in the county source CRS; no buffer, simplification or clipping. Duplicate river matches count each original county once. These are intersections between generalized river/cartographic county sources, not surveyed legal shoreline determinations. Unknown_count counts missing/invalid county geometries; do not silently treat them as no intersection. Keep source editions and all original IDs. Supplied water data is for this internal benchmark only.\n\n\n\nReturn an inspectable selected-feature artifact preserving original attributes, geometry and benchmark_row_id. End with one fenced JSON object: {count:integer,unknown_count:integer,coverage_note:string,selection:{collectionId,itemId,assetKey}}. List county names and state/GEOID, add the selected counties to this map, and include map_layer_id in that JSON.\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\": \"North American rivers, CEC 2023 frozen benchmark source\",\n    \"edition\": \"CEC North American Environmental Atlas version 4.0 (2023), original benchmark snapshot; benchmark-only use\",\n    \"units\": {},\n    \"collectionId\": \"blue-generated--[resource id withheld]\",\n    \"itemId\": \"[resource id withheld]\",\n    \"assetKey\": \"data\"\n  }\n]",
  "finalAnswer": "I found 115 counties touching the benchmark Mississippi River and added them to the map. Unknown_count is 0. The accepted result includes the inspectable selected artifact, the full county list with state/GEOID, and map layer `[resource id withheld]`.\n\nSources: CEC North American Environmental Atlas v4.0 (2023) benchmark river snapshot and Census TIGER/Line 2024 benchmark county snapshot, inspected 2026-10-07. These are generalized river/cartographic county intersections, not surveyed legal shoreline determinations.\n\n### Limitations\n\n- These are intersections between generalized river and cartographic county sources, not surveyed legal shoreline determinations.\n- The result reflects the supplied benchmark editions only: CEC North American Environmental Atlas v4.0 (2023) rivers and Census TIGER/Line 2024 counties.\n- This source is generalized cartography, not a legal shoreline record.\n- This is a cartographic source intersection, not a surveyed legal shoreline determination.\n- The displayed map layer is a view of the selected artifact; it does not change the selection logic.",
