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-kuic — the `.` special form + `.-field` field-access desugar on Chez. The

# analyzer lowers (. target member arg*) and (.-field target) to a :host-call;
|

# the Chez emit routes a non-shimmed :host-call through record-method-dispatch,
|
|
# which dot-forms.ss extends with field access + map/vector member dispatch.
|

# Each case carries its expected printed value.
