Exact submitted task and declared adaptations
How does forest coverage vary across Amazon Treaty countries? 

Task conventions: Use the frozen country polygons and World Bank AG.LND.FRST.ZS 2021 column, in % of land area. 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 NAME_EN in ["Bolivia", "Brazil", "Colombia", "Ecuador", "Guyana", "Peru", "Suriname", "Venezuela, RB"]; 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.



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.

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

I added the 2021 forest coverage layer to the map. Across the 8 retained benchmark country features, forest share ranges from 46.73% of land area in Bolivia to 97.33% in Suriname; all 8 countries had known 2021 values after the exact ISO_A3-to-Country Code join. The legend uses five quantile classes over those 8 countries: <50.98, 50.98–<52.97, 52.97–<56.95, 56.95–<79.81, and ≥79.81 % of land area. A neutral No data category is defined but unused here. This is a country-level 2021 comparison only, not a subnational forest surface or a new regional aggregate. ### Limitations - The comparison is country-level for 2021 only; it does not show subnational forest variation or a new regional aggregate. - This is a country-level 2021 indicator in percent of land area, not a subnational forest surface or a new regional aggregation. - Country membership follows the supplied GeoBenchX harmonized boundary benchmark edition. - Membership is fixed to the supplied GeoBenchX harmonized boundary edition. - The measurement is the frozen 2021 country-level World Bank indicator in percent of land area. - Values are classified only within the retained treaty-country geography. - Repeated values would reduce the class count, but the tested selection produced five classes.

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 exact requested workflow retain only the specified treaty-country boundary rows, join AG.LND.FRST.ZS 2021 by exact ISO_A3 to Country Code match, keep unknowns, and produce the requested quantile choropleth classes?

assess_trial · completed · assessment: sufficient

The trial retained exactly 8 boundary features for the supplied NAME_EN list, preserving original geometry and benchmark_row_id. The left join matched all 8 retained ISO_A3 values to Country Code with 0 unmatched input features. The joined 2021 field had 0 nulls in this frozen selection. Quantile classification on the retained geography produced 5 classes with breaks at 50.976702889519984, 52.96987283080132, 56.952563812048936, and 79.81021750151093 percent of land area; class counts were 2, 1, 2, 1, and 2, and the No data category remained available but unused because missingCount was 0.

assess_result · failed · requested assessment: sufficient

The delivered country layer keeps all 8 requested benchmark features and preserves benchmark_row_id, geometry, the 2021 forest-share value, and the class field. The exact ISO_A3 to Country Code left join matched all 8 retained countries, leaving 0 unknown values in this benchmark selection. Forest coverage ranges from 46.7283054555525% in Bolivia to 97.3336108974359% in Suriname. The final five-quantile legend uses breaks at 50.976702889519984, 52.96987283080132, 56.952563812048936, and 79.81021750151093 percent of land area; class counts are 2, 1, 2, 1, and 2, and the neutral No data class is available but unused because missingCount is 0.

  1. Progress update

    I’ll build this from the supplied frozen country polygons and the frozen 2021 World Bank forest-share table, then check that the join and five-class quantile legend behave as requested before I add the layer.

  19. Progress update

    I’m running one full private test on the exact requested geography now. I expect it to keep only the named country rows, leave any unmatched or missing 2021 values as unknown, and produce a five-quantile legend unless repeated values collapse a break.

  20. Progress update

    The first trial call was just an argument mistake: `inspect_outputs` belongs at the request level, not inside `computation`. I’m correcting that now and rerunning the same test.

  26. Progress update

    The private test succeeded on the full requested geography: it kept 8 boundary rows, all 8 joined by exact country code, and none were missing 2021 values in this frozen benchmark. I’m checking the final fields and legend details now, then I’ll save the tested workflow, add the layer to the map, and record the final answer.

  27. Progress update

    The test answered the method question, so I’m now extracting the exact classed values and saving the checked production workflow from that tested run. Then I’ll add the finished layer to the map and record the final result against the requested conditions.

    The test is confirmed: the exact requested subset has 8 features, all 8 matched the frozen 2021 World Bank code exactly, and the classifier produced 5 quantile classes with no unknowns in this particular selection. I’m recording that trial judgment, then saving the same tested computation as the finished workflow.

  40. Progress update

    I have the exact breaks and row values now. I’m saving the tested computation as the final workflow with the country-level limitation stated clearly, so I can run it once as the finished deliverable and bind that output to the map.

  42. Progress update

    The draft only needs one correction: its contract scope must exactly match the saved trial scope. I’m fixing that bookkeeping mismatch now without changing the tested computation.

  45. Progress update

    The workflow is now validated and matches the tested computation. I’m running that exact final workflow next, then I’ll verify the delivered artifact and map binding instead of relying on the private test output.

  46. Progress update

    The final run finished, so I’m inspecting the actual delivered output now rather than relying on the trial. Then I’ll bind that exact result to the map and record the final answer object from the inspected artifact.

    The final layer is already on the map. I’m pulling one last receipt for the delivered country layer itself so the final assessment cites the finished artifact, not just the trial.

  55. Progress update

    I’ve verified the delivered artifact and the final legend. I’m recording the accepted result now with the exact output selection and map layer binding.

  57. Progress update

    The result check only needs the acceptance conditions restated exactly. I’m resubmitting the same verified evidence with those exact condition texts now.
