Yogthos 7db5fabc8d resolve ^Type hint to canonical class name in var :tag 
(def ^String tv ...) left (:tag (meta (var tv))) as the unresolved "String";
the JVM compiler resolves the hint to java.lang.String at def time. Add a
resolve-class-hint host seam (built from the existing class-token table) and
resolve a def's :tag through it in the analyzer. The reader path
(read-string "^String x") stays unresolved, matching the JVM (only the
compiler resolves). Closes ^Type-tag-on-var.

Chez bootstrap seed

These two files are the bootstrap compiler for jolt-on-Chez — the seed that makes the build self-hosting with no Janet in the loop:

  • prelude.ss — the clojure.core prelude (all tiers + clojure.string/walk/ template/edn/set/pprint) as Scheme def-var! forms.
  • image.ss — the compiler image (jolt.ir + jolt.analyzer + jolt.backend-scheme) as Scheme def-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.
