eave
Let an agent explain eaves and their functions and forms, support design, maintenance and repair questions, describe regional eave traditions, and relate eaves to building regulations.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain eaves and their functions and forms, support design, maintenance and repair questions, describe regional eave traditions, and relate eaves to building regulations.
The lower edge of a roof that projects beyond the wall of a building, shedding rainwater clear of the walls and foundations, providing shade and shelter, and forming an architectural element in styles from deep Japanese eaves and decorative mokoshi skirt roofs to the covered gangi arcades of snowy regions and the double eaves of Chinese and Japanese temples; eaves are detailed with fascias, soffits and gutters and are regulated for drainage and fire safety.
What it is for: Projecting roof edges.
It can be explain functions and forms; support design and maintenance; describe regional traditions; relate to regulations.
