The type of a composed stack used as a runtime fetch entry. Annotating the
outermost handler with this (… satisfies FetchHandler) is the optional,
type-only anchor that lets the innermost handler see every upstream key
ambiently. It is not needed for cross-middleware dependencies declared as In
prerequisites — those type without any annotation.
