Yogthos f32bd335e3 test.check generators: rand-double, take +Inf, UUID/Long/shiftLeft, transient 
More general fixes from clojure.test.check's own suite.

- *unchecked-math* on doubles: unchecked-* only wrap integer math; on a flonum
  operand they're an ordinary float op (Clojure: (unchecked-multiply 1.5 2.0) =>
  3.0). test.check's rand-double is (* double-unit shifted) under *unchecked-math*
  and was truncating to a long 0, so every distribution-driven generator (choose,
  vector, …) collapsed to its lower bound.
- (take Double/POSITIVE_INFINITY coll) takes the whole coll instead of throwing
  on the infinite count coercion (rose-tree unchunk relies on it).
- (java.util.UUID. msb lsb) 2-long constructor (the uuid generator), formatted as
  the canonical lowercase 8-4-4-4-12 string; (Long. n) constructor; BigInteger
  .shiftLeft / .shiftRight (size-bounded-bigint); number methods now receive args.
- A transient (ITransientSet) responds to .contains / .valAt / .count
  (distinct-collection generators).

make test green (+3 corpus rows, 0 new divergences), runtime only (no re-mint).

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.
