#sort for moonx

Observed native/Wasm profile (2026-09-04): this README is supplementary. The support record is the only capability authority; it lists the repeatable unified-runner results and exclusions.

Sort lines of files or stdin:

moonx cli/sort names.txt
printf '10\n2\n' | moonx cli/sort -n
moonx cli/sort -t, -k 2 -u data.csv

Options include -r, -u, -b, -d, -f, and -i, plus -n numeric, -g general numeric, -h human numeric, -M month, and -V version comparisons. Repeated -k F[.C][OPTS][,F[.C][OPTS]] keys support field, character, and local comparison modifiers; -t BYTE selects a field separator. -z selects NUL records. -c/--check diagnoses the first disorder and -C/--check=quiet only returns status 1.

The deterministic profile compares transformed bytes under LC_ALL=C. Blank-separated fields retain their leading separator run unless -b applies; case folding maps lowercase ASCII to uppercase, and human numeric order compares sign, suffix magnitude, then numeric value. Key ties use the whole record as the last resort and remaining ties retain input order. -R is recognized but rejected before reading input because the package has no audited deterministic seed contract.

The implementation remains bounded to in-process sorting and never creates temporary files. With no file operand, it silently reads stdin until EOF.
