zipcodeR provides two deliberately separate interfaces.
Use functions ending in _ng with an explicitly selected data bundle. Start
with download_zip_data_bundle() for a registered immutable version or
read_zip_data_bundle() for a local checksum-pinned file. Passing the bundle
as the first argument makes the chosen data vintage visible in every call.
_ng never resolves an implicit latest version or downloads during a
lookup.
Unsuffixed functions and the datasets in data/ retain the exact zipcodeR
0.3.5 contract for existing scripts and research reproduction. This includes
historical data, scientific algorithms, conditions, ordering, and known edge
cases. Use zip_data_version() to record which contract an analysis used.
