Yogthos 4d61145e9c proxy [ThreadLocal] via thread-parameter; clojure.test/*testing-vars* 
- (proxy [ThreadLocal] [] (initialValue [] body)) now builds a real per-thread
  store backed by a Chez thread-parameter, with a lazy initialValue; .get/.set/
  .remove work. Other proxies stay nil. test.check's no-seed PRNG (next-rng) uses
  one, so gen/sample and gen/generate (and everything built on them) now work.
- clojure.test/*testing-vars* (+ *report-counters*) are bound vars now, so a
  defspec run through its :test metadata / default reporter doesn't hit an unbound
  var.

make test green (+1 corpus row), shakesmoke byte-identical. One re-mint (proxy).

Chez bootstrap seed

These two files are the bootstrap compiler for jolt — the seed that makes the build self-hosting:

  • 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.
