Exact submitted task and declared adaptations
Compare fertility rates between Eastern and Western African countries

Task conventions: Use the frozen country polygons and World Bank SP.DYN.TFRT.IN 2022 column, in births per woman. These are country-level indicators, not a subnational surface or a new regional aggregation. Join the supplied ISO_A3 to Country Code exactly. Nonmatching identifiers and missing measurements remain unknown; do not guess them or substitute another year. Retain every original country feature in the declared geography and its 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. Count original boundary features, not deduplicated sovereign states; preserve all source rows that meet the declared geography. Country-code sentinels such as -99 remain unmatched. Geography is fixed to original country features with SUBREGION in ["Eastern Africa", "Western Africa"]; retain all matching source geometries, and no others. Classification is calculated only over this geography. Membership reflects this disclosed benchmark edition, not current organization membership. Also compare unweighted means of known original country features by these fixed SUBREGION groups: {"Eastern_Africa": ["Eastern Africa"], "Western_Africa": ["Western Africa"]}. Do not treat missing values as zero. These are country comparisons, not basin-clipped or population-weighted estimates.



Add 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. Include a metrics object in the final JSON with group-name keys and their numeric means (or null if no known members), and explain the comparison.

Delivery 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.

Recorded final answer

Done. The 2022 fertility layer is on your map. Western Africa has the higher unweighted mean: 4.4128 births per woman, versus 3.8739 in Eastern Africa. The legend uses five quantile classes plus a separate No data class, with breaks at 3.6522, 3.9432, 4.3324, and 4.6626 births per woman. One retained country feature, Saint Helena, stayed unknown after the exact ISO_A3→Country Code join. The comparison follows the supplied benchmark edition and fixed Eastern/Western Africa membership, and it is an unweighted country average, not a population-weighted one. Sources: World Bank country boundaries benchmark fixture (GeoBenchX harmonized names) and frozen World Bank WDI fertility rate SP.DYN.TFRT.IN for 2022, hosted by Blue; retrieved 2026-10-07. Click the layer to inspect country values and classes. ### Limitations - Unmatched identifiers and missing 2022 measurements remain unknown. - The comparison uses the supplied benchmark edition and fixed SUBREGION membership, not current regional organization membership. - The Eastern and Western Africa comparison is an unweighted mean across known original retained country rows. - One retained feature, Saint Helena, remained unknown after the exact ISO_A3 to Country Code join. - The Eastern and Western Africa comparison is an unweighted mean across known original retained country rows, not a population-weighted mean.

Independent checks

These checks are separate from the agent's own assessment. A successful job or an assertion of success is not enough to pass.

Recorded investigation findings

The agent's reported hypotheses and assessments, retained as evidence of its process—not independent proof that the answer is correct. Failed calls retain their requested verdict, not an accepted assessment.

run_trial · completed

Does the fixed Eastern/Western Africa workflow retain the correct original country features, join the supplied 2022 fertility values exactly, classify them into quantiles with a distinct No data category, and produce the required unweighted subgroup means?

assess_trial · completed · assessment: sufficient

The tested method retained 35 original country features in the fixed geography, with 18 Eastern Africa rows and 17 Western Africa rows. The exact left join preserved all retained features and left 1 row unknown: Saint Helena (ISO_A3 SHN) had no matching Country Code and a null 2022 fertility value, which remained class 0 rather than being filled. Known 2022 values ranged from 1.32 to 6.749 births per woman, and the classifier produced classes 1 through 5 plus class 0 for No data. The subgroup comparison used known rows only and returned mean 2022 fertility of 3.873944444444444 for Eastern Africa and 4.4128125 for Western Africa.

assess_result · completed · assessment: sufficient

The delivered country artifact retains 35 original benchmark country features in the fixed geography, with 18 Eastern Africa rows and 17 Western Africa rows. The exact left join matched 34 rows and left 1 retained row unknown: Saint Helena (ISO_A3 SHN) has null Country Code and null 2022 fertility, and remains class 0 rather than being filled. The delivered choropleth uses five quantile classes over the retained geography plus a separate No data class, with breaks at 3.6522, 3.9432, 4.3324, and 4.6626 births per woman. The delivered subgroup summary uses known rows only and reports an unweighted mean of 3.873944444444444 births per woman for Eastern Africa and 4.4128125 for Western Africa, so Western Africa is higher by about 0.5389 births per woman. The delivered layer is on the map as layer [resource id withheld].

    Recorded tool call · completed

  41. Progress update

    The saved draft is almost ready. I only need to correct one bookkeeping mismatch: the workflow contract scope has to match the workflow’s executable scope exactly. Then I can run it and bind the final map layer.

  52. Progress update

    The final map output is already on your map as layer `[resource id withheld]`. I’m doing two bounded checks now: the final country artifact for the retained rows and unknown row, and the final summary/means so the recorded answer uses the exact delivered artifacts and legend.
