consume-join

a single-line declaration or assignment is followed directly by a return or switch that references what it binds

The same shape as guard-join with a return or a switch as the reader: a single-line declaration or assignment, then a return or switch that reads a name it binds, and the blank line between them goes. Only the declaration has to fit on one line. A multi-line return, like the object literal in the example, still joins.

throw is not a consumer. const error = new Error(message) followed by throw error is not joined by this rule (a two statement body still ends up tight, through short-body).

Outranked by short-body and after-multiline. A return that mentions the name only inside a callback, as in return () => use(kind), does not read it and does not join.
