Yogthos 829c251bca Host shims and protocol fixes shaken out by aws-api 
Running cognitect aws-api's pure test namespaces (signing/shapes/protocols/
util/retry/endpoints) surfaced general gaps:

- extend-protocol/extend-type accept a computed class type, e.g.
  (Class/forName "[B") for the byte-array class — the byte-array idiom data.json
  and aws-api use. The macro grouping handled only symbol/nil heads (it crashed on
  a list type); type->name resolves a Class value via .getName; a byte-array
  dispatches on the "[B" host tag.
- java.nio.ByteBuffer over a jolt byte-array (wrap/allocate/get/put/array/
  remaining/position/limit/duplicate/flip), plus extend-protocol to it.
- java.util.Arrays (equals/copyOf/copyOfRange/fill) and java.util.Random
  (nextBytes/nextInt/…).
- java.net.URI/create and clojure.lang.RT/baseLoader statics.
- clojure.core.async/promise-chan (deliver-once, peek-don't-pop).
- a failed java.time parse throws DateTimeParseException (typed), so
  (catch DateTimeParseException …) matches it instead of leaking an untyped
  condition.

The XML side lives in the jolt-lang/xml library (libxml2 over jolt.ffi); ByteBuffer
stays in core as a generic java.nio primitive.

Gate: make test green (corpus +6 JVM-certified rows, 0 NEW divergence; unit
553/553; SCI 211).

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. 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.
