Yogthos a67dbdb93d rand-nth follows the reference shape; refresh doc counts and the corpus floor 
rand-nth vec'd its argument, so (rand-nth nil) hit index-out-of-bounds
through the empty vector where the reference's (nth coll (rand-int (count
coll))) returns nil (and a set throws) — the last genuinely-fixable row in
the suite baseline; rand-nth is fully clean now. Corpus/README counts
updated to the current ~3570 rows, the run-corpus regression floor raised
from 2730 to 3390 to match current parity, and the stale traceability line
dropped.

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: ~3570 rows {:suite :label :expected :actual :portability}, 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. A known-fail allowlist 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 (see run-corpus.ss)

  • 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 :expr is evaluated in-process and its printed value compared to a baked :expected (:throws asserts a raise).

  • selfcheck.sh — self-host fixpoint: bootstrap.ss rebuild byte-equals the checked-in seed (host/chez/seed/).

  • smoke.sh — real bin/joltc -e CLI 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 per joltc process (a hang or crash is contained) through the test/chez/cts-app project and cts-run runner. Per-namespace fail/error counts must exactly match the checked-in baseline test/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,ns2 runs a subset verbosely, JOLT_CTS_WRITE_BASELINE=1 regenerates 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.
