Implement (type x) on the Chez RT (host/chez/natives-meta.ss). Mirrors the seed's core-type: the :type metadata wins when present, a record yields its ns-qualified class-name SYMBOL (user.TyR — no-ns sentinel #f so it = the overlay's (symbol (str t))), everything else a host-taxonomy keyword (:number/:string/:vector/:map/:set/:seq/:fn/…). Total by construction — a non-record value falling through to a crash would read as a divergence, so the cond covers every value type incl. the host wrappers (atom/volatile/regex/var/ transient/uuid -> :jolt/*, a :jolt/type-tagged map like ex-info -> its tag, sorted-set -> :jolt/sorted-set, sorted-map -> :map) and a final :object. Also pin sequential?/seq? on lazy seqs (test/chez/_seqpred.janet): the inc M seq? re-def-var! fix already covers sequential? transitively (sequential? is overlay and delegates to seq?), so no code change — the earlier "still broken" note was wrong, it assumed sequential? was native like seq?. Prelude corpus parity 2000 -> 2002 (the two type cases), floor raised, 0 new divergences. Gate: _type 37/37 + _seqpred 22/22 (both vs build/jolt oracle), emit-test 321/321, full jpm test, conformance 355x3.

# sequential? / seq? on lazy seqs (jolt-2o7x follow-up). The inc M fix made the
|
|
# native seq? var recognize a lazy-seq (re-def-var!, not just set!). sequential?
|
|
# is overlay (`(defn sequential? [x] (or (vector? x) (seq? x)))`), so it inherits
|
|
# the fix transitively; this pins that both predicates agree with the JVM oracle
|
|
# over every lazy-seq-producing form (and the native =/hash path via set!).
|
|
# Expectations are the build/jolt (JVM-canonical) values.
