NEXT.md prepends, so its second section still opened with "Read this first" while
pinning a tree six lanes behind and listing as live a queue most of which has
landed. It keeps its contents; what it gains is the sentence saying when it
stopped being where the tree is, and the survey count it quotes measured again on
this tree -- 103 MATCH, 0 DIFFER, 38 skipped.
The two generics entries get the file's own strikethrough treatment, which their
siblings already had: the {K V} catch resolved exactly as it predicted it would,
and there are five predicates rather than four.
Also here: conditions.org gains ArithError beside BoundsError, with the split
between the two runtime conditions that offer retry and the two that deliberately
offer nothing; and tast.ml's header stops naming a tree-walking interpreter among
the backends that consume the typed IR.
