One registered part, as the footprint-invalidation path index stores it: the
partition it belongs to and its index in that partition's children. A part's
path may be shared (duplicates) or empty (a pathless part, keyed by '', which
is a segment prefix of every absolute path — the same match the linear rule
nodePath.startsWith(childPath + '/') gave it).
