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-a73633bcf5d88743 descriptive

"nearly one-third of ticketed passengers on Budapest's metro network have switched to the Pay&GO contactless payment system"

Published field: impact · verbatim
Mapping: mapped · no interpretation or interpolation added by this passport
What the mapping says: The May 2026 article carries BKK's figures for the April 2026 extension to all metro lines, including the one-third share and the 12 per cent of all single ticket sales.
Caveat: Operator-supplied figures relayed by the press, not independently audited; the one-third share is metro-only and was measured within weeks of the full rollout.

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.
