Yogthos bb6c9eeb29 Class refinements: per-type class names, FQN tokens, instance? built-ins 
- (class x) returns per-type JVM class names (Long/Double/Ratio/Character/Atom),
  not a blanket java.lang.Number.
- register fully-qualified class tokens (java.lang.Long, clojure.lang.Keyword,
  clojure.lang.Atom, ...) that self-evaluate to their name, so (= (class 1)
  java.lang.Long) and (instance? clojure.lang.Atom x) resolve.
- instance? recognizes Long/Double/Ratio/Character/Symbol/Atom/IFn built-ins.

Closes class number/string/keyword/name, instance? Atom, atom?. Corpus 2699->2705.

Chez test harness

The correctness gate for jolt. Pure Chez (+ Clojure for the JVM oracle), no Janet. 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. 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 (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 :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.

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.
