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-bdf1fda6974190e0 quantitative

The city reported 80.37% overall progress at 30 June 2026

Published field: snippet · verbatim
Mapping: mapped · no interpretation or interpolation added by this passport
What the mapping says: The city's own notice carries the progress figure in its headline.
Caveat: Progress reported by the city that is building the line, not by the supervising engineer.

Alcaldía de Bogotá — Line 1 reaches 80.37% progress

Claim 2 clm-d5c3c549986d4e74 quantitative

ten of thirty CRRC Changchun trainsets delivered by April 2026

Published field: snippet · verbatim
Mapping: mapped · no interpretation or interpolation added by this passport
What the mapping says: The city's technical notice identifies the manufacturer and the Changchun works the trainsets and rails come from.
Caveat: The count of ten delivered is the city's running tally rather than a figure this notice states.

Claim 3 clm-31b25aca51e7a755 quantitative

energised automatic test runs began on the viaduct in May 2026 — with a technician in the cab, which the mayor says applies to testing only

Published field: snippet · verbatim
Mapping: mapped · no interpretation or interpolation added by this passport
What the mapping says: The May 2026 report covers the first controlled runs with citizens aboard, the event the entry dates and qualifies.
Caveat: The 'testing only' qualification is the mayor's statement, relayed by the press, not an operating rule anyone has published.

Claim 4 clm-a1c223cae1de8f82 quantitative

In January 2025 the national government deferred COP 770bn of its own contribution

Published field: snippet · verbatim
Mapping: mapped · no interpretation or interpolation added by this passport
What the mapping says: The report quotes the finance ministry decree suspending the stated sum for the Line 1 works.
Caveat: No claim-specific caveat recorded

Claim 5 clm-06b93805bd3718e8 quantitative

the supervising engineer put the works marginally behind schedule at mid-2025

Published field: snippet · verbatim
Mapping: mapped · no interpretation or interpolation added by this passport
What the mapping says: The July 2025 report summarises the supervising engineer's findings on delays, workplace accidents and disagreements.
Caveat: No claim-specific caveat recorded

Claim 6 clm-ab3e86b675816057 descriptive

Bogotá's is contracted, part-delivered and under test — and no source yet says whether staff will ride at launch

Published field: lesson · verbatim
Mapping: mapped · no interpretation or interpolation added by this passport
What the mapping says: The trade report covers the first trainset entering testing; nothing in it, or in the city's own notices, states the staffing arrangement for revenue service.
Caveat: Negative evidence: the absence of a staffing statement is the finding, and it can only be shown by what the sources do not say.

27 January 2025. The finance ministry's deferral decree suspended COP 770bn of budgeted national contributions to the metro; the district said the transfers 'no son un favor' and that it would cover the gap. A councillor filed a nullity action in February 2025 — the Concejo de Bogotá page documenting that filing returned HTTP 503 to automated fetch.

11 April 2025. Documents that the presidential campaign against the elevated design continued years after the 2023 attempt to bury the northern section failed; the district's position then was that a contract change was 'jurídicamente imposible y técnicamente inviable'. The alignment was never changed.

Context, deliberately kept out of the snippet: the joint audit with the Contraloría General found 22 findings and a fiscal finding of about COP 18.18bn, but these concern the FEEDER AND COMPLEMENTARY TRUNK WORKS contracted through TransMilenio, not the viaduct or the concession described here. Recorded so a future editor does not misattribute it to Line 1's construction contract.

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.
