2026-09-16, Lilleman auf Larv; revised 2026-10-07. Serves goals 5.2 and 5.7.
A category is one unit: a reference back into it — `{/users.first}` inside `users` —
describes a draw other than the fields beside it, so `New` refuses it and the sibling
field stays the one spelling for a field of one's own. A value two fields share goes in its
own category, which one field binds to a name and both read (goal 4.1). That settled, a record's column fences
run at `New` too, so a category that loads renders as a value and as a record alike.

2026-09-15, Lilleman auf Larv. Serves goal 6.1: a typed column's values are proven valid at
load, and composed text is not proven.
Its bounds come from a literal or a call's arguments, so a load error names a real
value and a range check is one comparison: `1{digits(2)}` is refused in a typed column,
