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-ba8e8247476ee01e quantitative

Rio's COR opened 31 December 2010, about eight months after April rains killed nearly 70 in the city and left 15,000 homeless

Published field: snippet · verbatim
Mapping: mapped · no interpretation or interpolation added by this passport
What the mapping says: Operator FAQ: the centre was inaugurated on 31 December 2010 and was set up after the temporal that struck Rio in April of that year. The network case study carries the casualty and displacement figures.
Caveat: The casualty and displacement figures rest on the network case study, whose host answers automated retrieval with HTTP 403, so no locating passage was read from it.

Claim 2 clm-a9854a5da853154c quantitative

as a $23m public-private partnership with IBM ($14m) and the city ($9m)

Published field: snippet · verbatim
Mapping: mapped · no interpretation or interpolation added by this passport
What the mapping says: Research write-up: the centre was a public-private partnership with IBM, which came up with a significant proportion of the financing; the network case study carries the split.
Caveat: The three dollar figures rest on the network case study, whose host answers automated retrieval with HTTP 403; the readable research source confirms the partnership and IBM's large share but gives no split.

Claim 3 clm-bb54c5e2e976cfdb quantitative

Today it integrates 60+ partner agencies and over 2,500 cameras in one room

Published field: snippet · verbatim
Mapping: mapped · no interpretation or interpolation added by this passport
What the mapping says: Operator FAQ, current state: about 2,500 cameras monitor every region of Rio, with 61 partner agencies, 23 of them in the control room, and 500 qualified staff.
Caveat: No claim-specific caveat recorded

Claim 4 clm-7755bc5d06a21d76 quantitative

cutting emergency response times by roughly 30%

Published field: snippet · verbatim
Mapping: mapped · no interpretation or interpolation added by this passport
What the mapping says: Independent policy write-up: the city has cut its emergency response time by more than 30 per cent.
Caveat: No claim-specific caveat recorded

Claim 5 clm-5c0e3bd7de191812 quantitative

Integrating 60+ partner agencies and over 2,500 cameras in one room, the centre is credited with cutting emergency response times by roughly 30%

Published field: impact · verbatim
Mapping: mapped · no interpretation or interpolation added by this passport
What the mapping says: The operator's own current counts of cameras and partner agencies, alongside the independent write-up that credits the centre with the response-time cut.
Caveat: The figure is credited to the centre rather than measured against a control; no source found compares it with a comparable city or a before-and-after design.

Claim 6 clm-dc0aa681145dec30 descriptive

the sixty-odd bodies inside the COR each keep their own powers and their own budgets

Published field: lesson · verbatim
Mapping: mapped · no interpretation or interpolation added by this passport
What the mapping says: Operator FAQ: the project integrates public bodies and concessionaires whose services affect the city's routine — the Alerta Rio warning system, the integrated mobility centre, CET-Rio and others — each named as a separate organisation.
Caveat: The FAQ gives two counts on the same page — 61 partner agencies, 23 of them in the control room, and 30 public bodies and concessionaires integrated by the project. The entry uses the larger figure and the source shows both.

Claim 7 clm-8f916736aeea5a52 descriptive

Rio built the room straight out of a disaster, with a private partner carrying a large share of the financing

Published field: lesson · verbatim
Mapping: mapped · no interpretation or interpolation added by this passport
What the mapping says: Research write-up on the public-private partnership with IBM; the independent policy write-up dates the centre's creation to the destructive 2010 storm and names IBM's support.
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-p1-quality-uplift effective 2026-08-27 · created 2026-08-26

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 2026-08-27T09:00:00Z. 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 2026-08-26T22:14:17Z on 2026-08-27; evidence: first appears in commit 788e6cc022, committed 2026-08-26T22:14:17Z.

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.
