The trail is twui's Breadcrumbs reading Home, the sections and the page
off the address, rendered as the first thing in SettingsShell's content
column, so every page that is not a conversation gets one without a page
touching it.
The last crumb is named by the page's own title rather than the address:
a record reads Scout instead of its id, /admin/logs reads Activity, and
/admin/settings/mcps reads MCPs. That replaces the breadcrumb_title prop
the four settings record pages had to pass, so settings-breadcrumbs.tsx
goes.
hasBreadcrumbTrail drops the trail on the crew of bots, home, and on
anything outside /admin; the trailing slash and query string are ignored,
so a folder in the files browser keeps the trail of the page it is on.
