// Single source of truth for the editor's primary navigation. Consumed by BOTH
// the sidebar (editor/app/layout.tsx) and the command palette
// (editor/app/components/CommandPalette.tsx) so they never drift — the old
// palette hard-coded a stale 5-item subset. Icons are used by the palette and
// the compact sidebar; `badgeKey` drives the live count pills / changelog dot.
//
// FOUR GROUPS, ONE NOUN EACH: the Corpus (what is on disk), the Operations that
// derive things from it, the Sites that publish it, and the Machine that runs
// it. That is the model in plans/editor-operations-ia.md, and the nav is where
// it is either true or not — a group called "Pool" holding ten unrelated tools
// was the shape of the problem, not a labelling accident.
//
// THE CAP IS THE RULE UMTOOL ALREADY WROTE, and it is quoted here rather than
// re-derived so the two consoles do not drift into two nav philosophies.
// umtool/components/AppNav.tsx: "SEVEN visible entries, and the cap is still
// NINE … The next tool goes UNDER one of these, not beside them — which is
// exactly what happened to the four judging piles and the sources page: they
// are the `song ▸` group now, at the same URLs they always had."
//
// So: FOLD, DO NOT ADD, and every retired route REDIRECTS rather than 404s
// (see editor/next.config.ts). The entries marked "interim" were folded by
// later slices; the end state is eleven, and slice 5 reached it (2026-08-30).
//
// A SECOND RECORDED EXCEPTION, at thirteen: /tags. A curated tag is a
// CORPUS noun — a vocabulary over videos, cutting across every channel and
// every site — and there is no channel, operation or site it could fold under
// without becoming that thing's property: under /sites it would be one site's
// word list, under /channels it would be per channel, and both are exactly what
// the feature is not. Agreed with the operator 2026-09-21; plans/curated-tags.md
// carries the same sentence.
//
// ONE RECORDED EXCEPTION, at twelve: /storage. A storage location is a place
// the machine keeps bytes — a Machine NOUN, like a worker or a job — and not a
// fold of Cleanup, which is an operation over bytes that already have a place.
// Agreed with the operator 2026-09-17; plans/editor-operations-ia.md carries
// the same sentence.

// /widget/builder IS NOT HERE, deliberately. The monitor widget is a PROJECTION

// screen — and a projection is not a place. It is reached from the pipeline
// band on the dashboard, which is the thing it mirrors.
//
// THAT COSTS IT THE COMMAND PALETTE, and the cost is stated rather than papered
// over: the palette renders NAV_GROUPS and has no way to type a URL, so leaving
// the nav removes it from the palette too. "monitor" and "widget" are keywords
// on Dashboard instead, which is where the link now lives — the palette takes
// you to the page that has it, not to a dead end.

// Flat list of every nav link (palette convenience).
