 # slug identically; a slug-keyed marker made the second one find the first

+# Classifies, not parses: three of the four are reachable as a declared set —
+# `{acme.widgets#9}` is not, because the clause parser stops at the `.` and
+# `blocked_reference_records` never hands that token through, though
+# `issue_references` does answer CROSS for it. It stays in the family because
+# the marker's contract is over the tokens the classifier admits, not over the
+# subset today's clause parser happens to reach; the class proof does not rest
+# on it either way, since `{acme-widgets#9}` vs `{acme_widgets#9}` is reachable
+# on both sides and reds the cheap fix on its own.
