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-r8ku (inc Y) — Chez-side Clojure data reader: read-string / read /
|

# read+string / with-in-str / clojure.edn. The reader (host/chez/reader.ss)
|
|
# produces jolt forms directly; the *in* family and
|
|
# clojure.edn are Clojure over the read-string / __parse-next seams.
|
|
#
|
|
# Outputs are kept order-stable (equality checks, scalars) so set/map iteration
|
|
# order — which is host-dependent — doesn't masquerade as a
|
|
# divergence.
