# ISC-WF-1 W1: named rulesets — bare use, recursive use (a ruleset
# using another), pass-structure inheritance (a ruleset's parallel
# block stays one pass at the use position), funcall pass-through, and
# use inside a parallel block (the expansion flattens into the
# enclosing pass, §3.2). Expectations verified by construction against
# the spec and pinned here; the selected-language paths live in
# tests/wf1.rs.
