Research direction

Start by locating the pluralize implementation and its make_quantity path, which is named in the warning. Reproduce the reported positive and negative boundary cases, then verify that quantities outside R's integer range remain comparable and pluralize completes without an NA-related error.

Written by the indexing model from the issue text.

Description

When trying to compare integers (but not doubles) outside of ±.Machine$integer.max, R returns NA, causing pluralize to fail, as qty != 1 cannot be properly evaluated.

# This works
(.Machine$integer.max + 1) != 1
#> [1] TRUE

# ...but this does not
as.integer(.Machine$integer.max + 1) != 1
#> Warning: NAs introduced by coercion to integer range
#> [1] NA
