Four delivery parts each wrote the same wiring of the seat-list reader
(start from the bootstrap, give the catalogue what it holds, read again
when events go live, two tools over a reader set later). seatlist.Part
is that wiring, its tools named by the part's prefix and its again
answered to the callers the part gives (ADR 0636 §7), so W4-W8 delete
their copies.
Builds: design 47 G §204, §246
