The unit tests in test/chez/_*.janet now drive bin/joltc (the zero-Janet spine) and judge against baked expected values instead of a live build/jolt run. Ten of them captured the oracle from build/jolt per case; their values are now literals (one env-dependent javastatic case became a predicate so it stays portable). The rest already had literal expecteds with a redundant build/jolt sanity check, now dropped. Retire emit-test/emit-parity/reader-parity: they compared the Chez/Clojure path against a live Janet evaluation, emitter, or reader. That migration check is done, and run-corpus-zero-janet (Chez analyzer vs the JVM corpus) plus certify.clj cover correctness now. Rewrite the README for the current zero-Janet gate. jolt-5oci

# 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 JVM-canonical values.
