// The nav's arithmetic, not its looks. The IA doc's end state is FOUR GROUPS

// satellites into /sites and the site's tabs. This test is what stops the
// twelfth entry from being added beside them instead of under one of them.

// THIRTEEN, and the twelfth and thirteenth are recorded exceptions rather than
// slips. The IA rule is "fold, do not add" and this test is where it is either
// true or not — so the number moves only when a plan says why. /storage is a
// Machine NOUN (a place the machine keeps bytes), not a fold of Cleanup (an
// operation over bytes that already have a place); /tags is a Corpus NOUN (a
// vocabulary over every channel and every site), which is precisely what it
// stops being if it is folded under one site or one channel. See nav.ts's
// header, plans/editor-operations-ia.md and plans/curated-tags.md.
