instance?, extend-protocol dispatch, isa?/supers/ancestors, and the exception hierarchy each read their own hand-kept table, and those tables had drifted: (instance? clojure.lang.Associative [1 2]) was true but a protocol extended to Associative wouldn't dispatch to a vector; keyword/IFn and seq/Seqable had the same split; (isa? ExceptionInfo RuntimeException) was false and (supers NumberFormatException) was empty. Add one FQN -> direct-supers graph (class-hierarchy.ss) and derive the views from it. value-host-tags builds on the graph closure so a vector reports Associative/Indexed/ILookup/Counted/Seqable, a keyword reports IFn, a seq reports Seqable/List/Counted, etc. instance? now tests membership in that same list, so it can't disagree with dispatch. canonical-host-tag recognizes any modeled class (was a separate literal set missing Seqable/ILookup/...). class-direct-supers unions the graph edges and class-supers returns the transitive closure, so the exception hierarchy answers isa?/supers/ancestors. The graph is open: jolt.host/register-class-supers! lets a library graft its own classes on and get every view for free. Runtime only, no re-mint. make test green (0 new/stale divergences), +3 JVM-certified corpus rows. |

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.
