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

# jolt-13zk — bare class-name tokens + (class x) on Chez. A class name (String,

# (class instance) returns — so (= String (class "x")) holds and a (defmethod m

# Scalar (class x) returns the JVM-style class-name symbol.

# Collection (class ...) is host-taxonomy-dependent and is NOT compared here.
