Volumes organise; they never renumber. An entry keeps its code wherever it is filed (§6.1).
No entry in this Part carries a page yet: each holds a code and a row and nothing more. The rows themselves live on the 14 group pages above, one click away; each code keeps its anchor there. That is the honest state of the Part, and a code without an article is still a permanent address — this page answers to it. Counts and order are read from register v60.25 at build time; they are not maintained here. The right column carries the year a house or brand was founded and the people in Part IX who anchor it; both are read from the pages the Library already publishes, so a row is bare where the Library does not yet hold the fact.
