Claims, one by one

The text below is copied verbatim from the published record. Each claim names the source dossiers that carry it; caveats stay attached to the claim they qualify.

Claim 1 clm-b9a8b07756a952a5 quantitative

puts Campo Grande's distribution losses at 20.69% — third lowest of Brazil's 27 capitals, against a capital average of 39.30%

Published field: impact · verbatim
Mapping: mapped · no interpretation or interpolation added by this passport
What the mapping says: The same Trata Brasil study that grades Manaus reports Campo Grande's loss rate and its rank among the 27 state capitals — the two cities share a concession group and sit at opposite ends of the table.
Caveat: The 56% starting point in the same impact line is the operator's own figure, not the study's.

Known limits of this passport

Publisher names and source languages have not yet been classified; domains are recorded without guessing.
Existing source notes are descriptive locators, not page- or paragraph-exact citations.
A missing archive, publication date or content hash is shown as null rather than inferred.
The project-level evidence grade ranks the strongest source in the entry; it is not a truth score for every claim.
