record-method-dispatch was rebound with (set! record-method-dispatch ...) in six files, each wrapping the previous binding, so precedence was whatever the rt.ss load order happened to be — the true outermost arm was inst-time's Date arm, not the one you'd guess. A type-gated wrapper that only whitelists its own methods then errored on everything else, stealing universal Object methods from the arms beneath it: (.getClass (java.util.Date.)) threw "No method getClass on Date", same for File, while (class ...) and (.getClass "s") worked. Replace the wrapper stack with an ordered list of arms (register-method-arm!, ascending priority), each returning 'pass to defer. getClass is now one arm at the top reached by every value, so it can't be shadowed; the three duplicate getClass checks (dot-forms, host-static, base) collapse into it. Each former wrapper is an arm at an explicit priority instead of an implicit load-order slot. A library can register its own arm rather than set!-wrapping the dispatcher. Runtime only, no re-mint. make test green (0 new/stale divergences), +1 corpus row for getClass on Date/File. |

Chez test harness
The correctness gate for jolt. Pure Chez (+ Clojure for the JVM oracle).
Correctness is judged against the JVM-sourced conformance spec; the spec itself
lives in test/conformance/ (see its SPEC.md). Run the whole gate with make test from the repo root.
The spec corpus
corpus.edn is the contract: ~2920 rows {:suite :label :expected :actual}, with
:expected sourced from reference JVM Clojure by test/conformance/regen-corpus.clj.
It is frozen (the canonical source) — add or change cases here, then re-source the
answers with regen-corpus.clj and re-certify with test/conformance/certify.clj.
The gate runners (host/chez/)
-
run-corpus.ss— runs every corpus case through the spine (read → analyze → IR → emit → eval, all on Chez), comparing each result by value-equality against the JVM:expected. Aknown-failallowlist covers cases jolt can't match because Chez has no JVM host (Java classes, arrays,BigDecimal, opaque host-object printers, …); the gate fails only on a NEW divergence or if the pass count drops below the floor.chez --script host/chez/run-corpus.ss JOLT_CORPUS_LIMIT=200 … # every-Nth stride, fast iteration JOLT_CHEZ_ZJ_FLOOR=N … # override the floor (default 2678) -
run-unit.ss— host-specific unit cases (test/chez/unit.edn) that aren't in the JVM-portable corpus: dot-forms, java statics, io, reader, walk, vars/namespaces, refs. Each:expris evaluated in-process and its printed value compared to a baked:expected(:throwsasserts a raise). -
selfcheck.sh— self-host fixpoint:bootstrap.ssrebuild byte-equals the checked-in seed (host/chez/seed/). -
smoke.sh— realbin/joltc -eCLI smoke.
Other Chez tests
values-test.ss— the value model (nil/truthiness/collections).make values.bench-chez.ss— compute bench through the pipeline (opt-in; not in the gate).
All runners assume chez on PATH.
