Yogthos f46772d576 fd subsystem: instance? name-boundary + ~ reads as clojure.core/unquote 
Two general fixes that clear core.logic's finite-domain -difference, safefd, and
the defne quoted-list patterns (form->ast), taking the suite to 532/5/0.

- instance? on a deftype matched a simple type name against the qualified tag by
  raw string suffix, so "a.b.MultiIntervalFD" tested true for IntervalFD. The
  suffix must land on a "." boundary. core.logic's fd dispatches on
  (interval? x) = (instance? IntervalFD x), and a MultiIntervalFD wrongly counted
  as an interval, so -difference/safefd computed the wrong set.
- the reader reads ~ / ~@ as clojure.core/unquote(-splicing), like the JVM reader,
  instead of a bare unquote. Code that inspects quoted pattern/template data —
  core.logic's defne checks (= f 'clojure.core/unquote) — now sees the symbol it
  expects, so '(fn ~args . ~body) patterns compile. hc-head-is? accepts the
  qualified head in syntax-quote lowering; the value-preserving change leaves the
  minted seed byte-identical.

corpus.edn: 2 JVM-certified unquote rows. unit.edn: two reader rows updated to the
qualified unquote. make test + shakesmoke green, 0 new divergences, self-host holds.

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.
