max / goingson

Name goingson's row members on the type that holds them Wave 2b, and the lane that had the least in it. goingson is the list-heavy tree -- 50 lists against 2 tables -- and it compiled against the merged vocabulary without a single edit. Its 110 measured sites are all constructor calls, and the merge kept every one of them. That is the evidence for ruling 4 rather than an absence of it: the tree that writes lists almost exclusively did not notice that a list became a one-column table. `current`, `selected` and `chosen` are still three fields and the bulk paths still read the one they meant. So the only change is prose: two references to `Cells::ticking`, which is `Row::ticking`. The six `-> Cells` shape return types stay as they are; `declare!` reads that token to pick the body form. 922 lib tests green, clippy clean with -D warnings.
