# Deduplicate lines

Build-time release reference. Runtime readiness, deployment, payment settlement and external indexing are not evaluated here. Prices are proposed; this file cannot authorize execution or payment.

Use to remove repeated records from newline-delimited text while keeping the first original spelling and order. Comparison optionally trims whitespace and uses locale-independent lowercase. Output separators become LF; no fuzzy matching or Unicode normalization. Empty text has zero lines; a trailing newline represents a final blank line.

Release: 0.29.0. Built: 2026-10-06T15:38:00Z.
