Running clojure/core.logic's own suite surfaced a batch of general jolt gaps.
None are core.logic-specific; each is a language/host behavior that was wrong or
missing. With these, the core relational engine (unify, run/fresh/conde,
conso/membero/appendo, reification to _0/_1, lcons) runs; the remaining failures
are in core.logic's constraint-logic-programming and finite-domain layers
(tracked separately).
- analyzer: accept the list-member dot form (. target (method args)), sugar for
(. target method args). Re-mint.
- identical? is reference identity (eq?), not value equality. It was aliased to =,
which infinite-loops when a deftype's .equals short-circuits on (identical? this o)
(core.logic's Substitutions) and is wrong for distinct equal collections.
- jrecs use a deftype's declared hashCode/equals/equiv for map/set keying instead
of structural field comparison, so metadata-wrapped keys still match (core.logic
keys substitutions on lvar id, ignoring metadata).
- meta/with-meta dispatch to a deftype's clojure.lang.IObj meta/withMeta methods
when present, so metadata threaded through the type's own assoc/withMeta survives
(previously kept in an identity side-table the reconstructed instances didn't share).
- coll?/seqable? on a deftype require IPersistentCollection (cons) or ISeq (first);
ILookup(valAt)/Indexed(nth)/Counted(count)/Seqable(seq) alone no longer qualify,
matching the JVM.
- syntax-quote resolves a bare symbol to the compile ns's own def before
clojure.core, so a name the ns excluded and redefined (core.logic's == after
:refer-clojure :exclude) qualifies correctly in macro output.
- reader: record literals #ns.Type{...} / #ns.Type[...] expand to the map->/->
factory call.
- structmap API: defstruct/create-struct/struct-map/struct/accessor (map-backed,
insertion-ordered). Re-mint.
- .hashCode on strings/symbols (Java String.hashCode, Symbol Util.hashCombine);
Class.isInstance; java.util.Collection.contains over vector/list/set;
clojure.lang.RT/nextID and clojure.lang.Util hash/hasheq/equiv/identical statics.
corpus.edn: 8 JVM-certified rows. unit.edn: a Counted+Seqable deftype is coll?=false
(was a stale expectation encoding the old behavior).

Chez bootstrap seed
These two files are the bootstrap compiler for jolt — the seed that makes the build self-hosting:
prelude.ss— theclojure.coreprelude (all tiers + clojure.string/walk/ template/edn/set/pprint) as Schemedef-var!forms.image.ss— the compiler image (jolt.ir+jolt.analyzer+jolt.backend-scheme) as Schemedef-var!forms.
Both are generated, not hand-written. They are checked in because a fresh
checkout must be able to build jolt-on-Chez using only Chez: host/chez/bootstrap.ss
loads this seed, then rebuilds the prelude + image from the .clj/.ss sources via
the on-Chez compiler (read → analyze → emit, all on Chez). The seed is a joint
byte-fixpoint: rebuilding from an up-to-date seed reproduces it exactly.
make selfhost (host/chez/selfcheck.sh) runs host/chez/bootstrap.ss and diffs
the rebuilt artifacts against the checked-in seed.
Re-minting
When the seed sources change (the core tiers, the compiler namespaces, the host
contract, the reader, emit-image.ss), the seed drifts and make selfhost
fails. Re-mint it by running host/chez/bootstrap.ss and writing the freshly
rebuilt prelude/image back to host/chez/seed/prelude.ss /
host/chez/seed/image.ss, then commit the refreshed files.
