 `checkCalc` and the value proof read an operand as a sibling field, so `{calc(n * 2)}` is refused with `no field "n"` today. Item 4 stops an operand holding its field for the expansion, after which a name is the one way to show the operand a calc computes from, as the README's Computation example does.

 The decision "With only the shipped set, a category loads on the first call reaching it; beside a `--data-path`, every category loads in `New`" parses the whole shipped set on every `--data-path` run, about 45 ms today and seconds once items 61 and 78 land. Goal 6 needs only the user's categories, the shipped ones they override, the shipped ones they read, and the shipped ones whose reads reach an overridden category, so the index would carry each category's reads.
