## Frequently asked questions

### Does deduplication keep the first or the last copy?

The recommended path uses global detection with keep-first, so the earliest line remains in its original position. Choose keep-last only when the newest copy is authoritative, and record that exception because it changes both the displayed value and its position.

### Are `Alpha` and `alpha` duplicates?

Only if case-insensitive matching is enabled. Use case-sensitive matching for IDs, codes, and values where capitalization is meaningful; case-insensitive matching is appropriate only when case is presentation noise.

### Should blank lines be removed before deduplication?

Remove them for a compact one-item-per-line deliverable, but do not treat them as duplicate items. Preserve them, or keep a separate copy, when they mark sections or are needed to reproduce the source layout.

### Why not use random shuffle to make the list look less biased?

Random shuffle makes two runs differ and prevents a reliable diff or audit. If a different order is needed, choose alphabetical, numerical, or length sorting and save the selected direction instead.
