Both thresholds are strictly greater than. Count source records, retaining benchmark_row_id; repeated GNIS IDs are not a deduplication instruction. Sample the pixel containing each point. Report the count supported by valid snowfall cells, and separately the number of population-eligible records whose snowfall is unknown (outside coverage or NoData). Do not claim complete nationwide coverage.\n\n\n\nCompute the answer using only the supplied immutable fixtures. Save the selected features with their benchmark_row_id and original geometry as an inspectable data artifact. In your accepted final answer include one JSON code block with count (integer), unknown_count (integer), coverage_note (string), and selection (an object with collectionId, itemId, assetKey for that artifact). Maps are optional. Do not request clarification: the task conventions are fixed. Do not use live substitutes, shrink the study question, or use external benchmark answers.\n\nDelivery format: provide the answer object with all fields specified above as final_response on assess_result, alongside the inspected final artifact_refs.
