Close clojure.spec.alpha's remaining gaps — its conform/explain/describe/multi-spec
suite (clojure.test-clojure.spec, multi-spec) now passes fully.
- (get reify k) / (:k reify) routes to a reify's clojure.lang.ILookup valAt. spec
reifies fspec/regex specs as ILookup and reads (:args spec) off them, so before
this instrument never saw the args spec.
- A failed numeric comparison reports the JVM class: a nil operand is
NullPointerException, a non-number is ClassCastException (was an opaque :object
condition). conform-explain checks the thrown class.
- A quoted / macro-form #inst / #uuid literal constructs its Date/UUID value, like
the JVM reader (which builds it at read time). emit-quoted was emitting the raw
tagged form, so #inst "1939" and #inst "1939-01-01T00:00:00.000-00:00" weren't =.
- An anonymous fn reports class clojure.lang.AFunction$fn (the $fn marker), so
spec's fn-sym returns ::s/unknown for it, matching the JVM's ns$fn__N.
- A fn with & {:as m} kwargs accepts a trailing map (Clojure 1.11): (f :a 1 {:b 2})
and (f {:a 1}) both bind m, by merging an odd trailing map over the pairs.
- A thread responds to .getStackTrace (empty — jolt does TCO).
clojure.test-clojure.instr does not fully pass: its ::caller assertions need the
calling fn's stack frame, which TCO erases (an inherent host divergence, like the
JVM keeping tail frames).
make test green (+4 corpus rows, 0 new divergences), shakesmoke byte-identical.
Re-mint (backend emit-quoted + the destructure macro).
jolt fns reported (class f) = clojure.lang.IFn, so they carried no defining
symbol — clojure.spec.alpha's fn-sym (which reads a fn's class name to recover its
symbol) produced garbage, so explain-data's :pred for a bare-fn predicate was `/`
instead of e.g. clojure.core/keyword?.
Now def-var! records proc -> (ns . name) (first def of a proc wins, so an alias
like (def inc' inc) doesn't rename inc), and jolt-class-name returns "ns$munged"
for a known fn — matching the JVM, where (class odd?) is clojure.core$odd_QMARK_.
A munged fn class's ancestors include clojure.lang.AFunction's hierarchy
(IFn/AFn/Fn/Runnable/Callable), so (ancestors (class f)) still holds. Anonymous /
unregistered fns stay clojure.lang.IFn (fn-sym yields :unknown, as on the JVM).
This fixes explain-data / s/form / s/describe of bare-fn predicates in
clojure.spec.alpha (and unblocks parts of its suite + test.check's reporter test).
make test green (+1 corpus row, the (type inc) unit row updated to the JVM value),
shakesmoke byte-identical, runtime only (no re-mint).
jolt had Long/Integer/Double class tokens but not Byte/Short/Float, and no
Byte/Short MIN_VALUE/MAX_VALUE/valueOf/parse* statics. clojure.test.check (a
malli dependency) references Byte/MIN_VALUE and Byte/MAX_VALUE. The values are
plain integers on jolt; the statics expose the JVM ranges (127/-128, 32767/
-32768).
A wrong-arity or non-seqable error that Chez raises carried no jolt exception
class, so (class e) was :object and (thrown? ArityException …) / (thrown?
IllegalArgumentException …) never matched. Classify these by message:
incorrect-number-of-arguments -> clojure.lang.ArityException, not-seqable ->
java.lang.IllegalArgumentException, with ArityException modeled as a subclass of
IllegalArgumentException. (class e) and instance? now match the JVM.
All java-layer (records-interop.ss classifies, host-class.ss reports the class +
the ArityException token). medley 281 -> 283 passing.
jolt-o9dc
(type x) was jolt's internal taxonomy keyword (:string/:set/:jolt/inst), which
breaks any library dispatching a multimethod on [(type a) (type b)] against
java/clojure.lang classes (e.g. clojure.tools.logging.test's matchers). Make the
PUBLIC clojure.core/type Clojure's (or (:type meta) (class x)).
The taxonomy keyword stays the core model: natives-meta.ss keeps jolt-type and
exposes it as __type-tag, which print-method/print-dup dispatch on (so #uuid/#regex/
records still print). The JVM mapping lives in the java host layer — host-class.ss
defines the public type next to (class …), and a jinst now reports java.util.Date
(was :jolt/inst). So the core emits the taxonomy and the java layer remaps it in one
place. unit.edn's type suite updated to the class names. make test green.

Class/forName claimed every java.*/clojure.* name found (and any "x.y.Class"
matched the registered Class via a short-name fallback), so a library's
(class-found? "optional.Dep") feature-probe always said yes — tools.logging then
tried to build the java.util.logging / log4j backends jolt lacks and crashed.
Resolve forName by exact registry lookup + an honest prefix that excludes the
unbacked optional packages (java.util.logging, javax.management), so the probe
sees them absent and skips the backend.
class of a persistent collection / namespace now reports its JVM class name
(clojure.lang.PersistentHashSet, …Namespace, …) instead of jolt's internal :set/
:object tag, and isa? consults JVM class assignability — Object as every class's
root plus a modeled clojure.lang/java.util hierarchy — so (isa? (class x) C) and a
class-keyed multimethod dispatch like the JVM (e.g. (isa? Keyword Object) was
false). Adds the bare class tokens (Fn/Namespace/Set/…) these dispatch on.
(type x) is unchanged — it keeps jolt's documented internal-keyword form. Six
JVM-certified corpus rows. make test green, 0 new divergences.

The host/chez directory mixed jolt's own runtime (value model, seq, reader,
vars, ns, multimethods) with the shims that emulate the JVM: java.* / javax.*
classes, clojure.lang interfaces, and the host-class registry they hang off.
Move that JVM-emulation layer into host/chez/java/ so it reads as a distinct
unit instead of being interleaved with the platform runtime.
Moved (content unchanged): host-static, host-static-methods,
host-static-classes, host-class, dot-forms, records-interop, byte-buffer,
io, io-streams, inst-time, java-time, bigdec, natives-queue, natives-str,
natives-array, math, concurrency, async, ffi.
The load paths in rt.ss/cli.ss and the build.ss runtime manifest are updated
to point at java/; the build inliner follows the (load ...) strings, so the
AOT path needs no other change. All runtime shims, no seed source touched
(the three .clj edits are doc comments), so no re-mint.
Gate green: make test (selfhost fixpoint, certify 0-new, sci 211, infer),
shakesmoke (4 apps byte-identical).
