Mapping: mapped · no interpretation or interpolation added by this passport
What the mapping says: The legislative analysis covers the constitutional alteration that moved railways off the exclusive list, which is the change the entry dates to March 2023.

Published field: snippet · verbatim
Mapping: mapped · no interpretation or interpolation added by this passport

Fetched OK. Project description naming CCECC as builder and listing an operations control centre, SCADA and ATP with in-cab signalling — written in future tense before opening, so treated as planned rather than confirmed delivered. Its cost estimates conflict with state figures and are not used.

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.
