# Clojure conformance harness (phase 1: extracted assertion pairs).
#
# Each case is [name expected-clj actual-clj]. The harness evaluates the
# single Clojure program (= <expected> <actual>) inside a fresh jolt ctx
# and asserts it returns boolean true. Comparison therefore uses jolt's OWN
# `=`, which implements Clojure sequential/collection equality -- so results
# reflect real Clojure semantics rather than Janet-level identity.
#
# `actual` may be a multi-form body; wrap such cases in (do ...).
#
# Source of truth: ~/src/clojure/test/clojure/test_clojure/*.clj
# These pairs are hand-extracted from those files (and canonical idioms)
# until a minimal clojure.test lets us load the real files directly.
