byte/short/int/long/char silently wrapped or passed out-of-range values through; the JVM range-checks (RT.byteCast family). One checked-cast helper now carries the ranges: a double range-checks ITSELF before truncating ((byte 1.1) is 1, (byte 127.000001) throws), NaN casts to 0, ratios and bigdecs truncate, a non-number is CCE, and the throw carries the JVM message. float range-checks against Float/MAX_VALUE. The unchecked-* casts now genuinely wrap and sign-fold ((unchecked-byte 200) is -56 — the old bit-and lost the sign) with doubles saturating like Java's conversions; unchecked-long/int are host natives. double/float of a bigdec convert instead of crashing. The no-single-float residue stays accepted (SPEC.md). Also fixes #290: a binary built by the SELF-CONTAINED joltc died with 'variable var-deref is not bound' when a namespace loaded at runtime. The in-process build compiled flat.ss against a clean copy-environment, which orphans every top-level define in locations the binary's runtime eval can't see. It now compiles against the default interaction environment (defines land in the real symbol cells, same as the legacy fresh-Chez path) and a generated prologue pre-binds each kernel name the runtime redefines to its kernel value, so the earliest boot reads match the legacy path's primitive references. requiring-resolve is implemented (the issue's dynamic-require pattern), and the release workflow smokes a runtime require in a built binary. Cast namespaces byte/short/int/long/char now fully clean; cts baseline 5805 -> 5857 pass, 67 baselined namespaces. 7 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. -
cts.sh— the vendored jank-lang/clojure-test-suite (vendor/clojure-test-suite, a per-core-fn clojure.test suite shared across Clojure dialects), run one namespace perjoltcprocess (a hang or crash is contained) through thetest/chez/cts-appproject andcts-runrunner. Per-namespace fail/error counts must exactly match the checked-in baselinetest/chez/cts-known-failures.txt— a namespace doing worse fails the gate, and one doing better fails as stale until the baseline is updated in the same change.make cts;JOLT_CTS_NS=ns1,ns2runs a subset verbosely,JOLT_CTS_WRITE_BASELINE=1regenerates the baseline.
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.
