Changes in version 1.0.0 (2026-05-05)                  

Data pipeline

  - The data-raw/ ETL pipeline can now be run as a targets pipeline
    (targets::tar_make()), replacing the flag-driven run_pipeline.R
    orchestrator. Pipeline functions live in data-raw/R/; the legacy
    scripts remain and produce identical output. See CLAUDE.md for the
    workflow.

Datasets

  - metro_lines is no longer exported. Its line-name columns (line_name,
    line_name_pt) are already denormalized onto every passenger/station
    dataset, and the full line list (including planned and CPTM lines)
    is available in lines. It remains an internal join dimension in the
    ETL pipeline.
  - station_daily$line_number / station_daily$year are now integer
    (previously double), matching the other datasets. Values are
    unchanged.

  - Initial CRAN submission.
