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-537b3d65df0b6890 quantitative

São Paulo's city hall has run the CGE since November 1999, after a flood filled the Anhangabaú tunnel

Published field: snippet · verbatim
Mapping: mapped · no interpretation or interpolation added by this passport
What the mapping says: The operator's own page states the centre was 'criado em novembro de 1999' and links it to the municipal infrastructure secretariat.
Caveat: No claim-specific caveat recorded

Sources carrying this claim

CGE — Quem somos (Prefeitura de São Paulo)

Claim 2 clm-d7b2a06dae057675 quantitative

It reads its own automatic weather stations and rain gauges in 32 subprefeituras alongside the state DAEE radar and Alto Tietê telemetry

Published field: snippet · verbatim
Mapping: mapped · no interpretation or interpolation added by this passport
What the mapping says: The monitoring page names the rain gauges across 32 subprefeituras and the SAISP radar at Salesópolis as the primary radar; the sources page states plainly that the radar is 'operado pela FCTH… de propriedade do DAEE' — state property — and that the telemetric network is likewise consumed rather than owned.
Caveat: No claim-specific caveat recorded

SAISP — Rede Telemétrica do Alto Tietê (DAEE/FCTH)

Claim 3 clm-6f13f1b0cda23c4e descriptive

then declares an estado de atenção or alerta zone by zone

Published field: snippet · verbatim
Mapping: mapped · no interpretation or interpolation added by this passport
What the mapping says: The operator describes the graded states it declares by zone; the January 2026 news report records CGE-declared alert states during storms in the city.
Caveat: No claim-specific caveat recorded

Sources carrying this claim

CGE — Quem somos (Prefeitura de São Paulo)
Agência Brasil — storms put the city of São Paulo on alert (Jan 2026)

Claim 4 clm-04abe549e5397037 descriptive

The public flood-point map is not sensed — municipal traffic agents on the street report each alagamento and grade it transitável or intransitável

Published field: snippet · verbatim
Mapping: mapped · no interpretation or interpolation added by this passport
What the mapping says: The classification page states that the flood information 'são fornecidas pelos agentes de campo (trânsito) da Prefeitura' and sets out the two grades.
Caveat: No claim-specific caveat recorded

Sources carrying this claim

CGE — Classificação dos alagamentos

Claim 5 clm-bdf29667d69306da descriptive

An alert pre-positions crews and warns drivers; it opens no gate and starts no pump

Published field: snippet · verbatim
Mapping: mapped · no interpretation or interpolation added by this passport
What the mapping says: Nothing in the operator's description of the centre gives it an actuator: it declares states and informs. The counterweight is the reported death of a driver trapped in a car during a São Paulo flood on 1 February 2025.
Caveat: No claim-specific caveat recorded

Sources carrying this claim

CartaCapital — driver killed in a São Paulo flood, 2 Feb 2025

Claim 6 clm-8fef74bc932b6630 descriptive

A live flood map can look like sensing and not be

Published field: lesson · verbatim
Mapping: mapped · no interpretation or interpolation added by this passport
What the mapping says: The city's own classification page attributes the flood points to field traffic agents rather than to instruments.
Caveat: No claim-specific caveat recorded

Sources carrying this claim

CGE — Classificação dos alagamentos

Claim 7 clm-b9401fee37d9e47e descriptive

so its coverage follows the main roads they patrol — and it records water that has already arrived rather than predicting it

Published field: lesson · verbatim
Mapping: mapped · no interpretation or interpolation added by this passport
What the mapping says: Because the points come from traffic agents on patrol, the layer is bounded by where they are; the peer-reviewed 2013 study that uses the CGE/CET flood-point data treats it as an observational record of flooding that has occurred.
Caveat: No claim-specific caveat recorded

Source dossiers and revision state

This layer records what is known about each source, what is still missing, and the exact snapshot this page is rendering. A missing date, archive or hash stays visible as missing.

unreviewed Revision 2026-08-27-claims-and-sources effective 2026-08-27 · created 2026-08-27

Awaiting operator and domain-expert review; publication of this revision implies neither.

Erratum on this revision's envelope. The snapshot, its hash and its permanent link are untouched.

createdAt previously read 2026-08-31T12:00:00Z. The batching script that produced this revision advanced createdAt into the future to satisfy the strictly-increasing order the validator requires per entity. The value never recorded a real event; the corrected value is the moment the revision provably existed in the repository. Corrected to 2026-08-27T03:13:38Z on 2026-08-27; evidence: first appears in commit 7a13833ce6, committed 2026-08-27T03:13:38Z.

Disambiguation source. The STATE Defesa Civil opened its own Centro de Gerenciamento de Emergências at the Palácio dos Bandeirantes on 13 Feb 2025 (R$47.1M with the Cepram radar centre); the cellphone alerts come from there, not from the municipal CGE. Two different bodies sharing an acronym — deliberately not merged into this entry.

Counterweight. On 1 Feb 2025 an app driver died on Rua Prece, Vila Prudente, after his car stalled crossing standing water. Verified at search-snippet level across four outlets (CartaCapital, Jovem Pan, Terra, Diário do Grande ABC); direct fetch not attempted. The accompanying "18th victim" figure is a STATE Defesa Civil count for the whole state since December, not a city figure, and is therefore not used in the entry.

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.
