#comm for moonx

Version 0.2.1 behavior is documented here. The support record separates local verification from published MoonX behavior; moonx examples use registry releases.

Compare two sorted files line by line, producing three columns: lines only in FILE1, lines only in FILE2 (one leading TAB), and common lines (two leading TABs):

moonx cli/comm left.txt right.txt
moonx cli/comm -12 left.txt right.txt   # only common lines

Options: -1, -2, -3 suppress the corresponding column (combinable as -12, -23, ...). Use - to read stdin. Records are compared as raw bytes, matching LC_ALL=C order. --check-order reports an unsorted input and exits nonzero. By default, disorder is diagnosed once unpairable input is observed, matching GNU's conditional check. -z reads and writes NUL-delimited records; --nocheck-order explicitly selects permissive order handling whenever both order flags are present.

#Standalone metadata

Standalone --version prints exactly comm 0.2.1 followed by one newline. Standalone --help starts with Usage: comm, lists both metadata options, and ends with a newline. Both write to stdout, leave stdin unread, and exit with status 0. Exact-version publication and verification remain recorded separately in the support record.
