apple
Let an agent handle apples as food and as a crop, distinguishing cultivars, quality grades, storage and residue rules, and separating the fruit from the tree and the company name.
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.

Let an agent handle apples as food and as a crop, distinguishing cultivars, quality grades, storage and residue rules, and separating the fruit from the tree and the company name.
The fruit of the apple tree (Malus domestica), a pome eaten fresh, cooked or pressed, grown in thousands of named cultivars.
What it is for: Eating, cooking, juice, cider and trade.
It can be eat it, fresh or cooked; grow and harvest it, in orchards; store it, for months in controlled atmosphere; grade and trade it, under marketing standards.
