# HUD

### Definition

Alias for [Highest Uncommon Denominator]. Not a separate mechanism -- a shorthand reference to the same locked entry.

### Explanation

See [Highest Uncommon Denominator] for the full definition and mechanism. HUD exists in source material as a compressed reference where the full bracketed term would otherwise repeat -- it carries no content beyond what's already locked there.
