History and cultural context
The mansion system developed as a way to organize the belt of sky traversed by the Moon and became embedded in calendrical, court and astrological practice. Root belongs to the seven-mansion sequence of the Azure Dragon of the East; historical catalogues may differ in which faint stars are included.
How Root maps the sky
A Chinese mansion combines a reference asterism with a strip of right ascension extending toward the celestial poles. It therefore cannot be reduced to either the similarly named IAU region or a single Western line figure.

How it fits the combined catalogue
The directory stores Root as one canonical entry and uses badges for membership and overlap, rather than duplicating it under every official constellation it touches.
Research and cultural care
English mansion names are translations, not replacements for the Chinese terminology. Preserve the Chinese reading and avoid treating the Four Symbols as Western-style giant constellations.
