Yogthos 8ce00d29fd embed a namespace value spliced into a form (~*ns*) 
A macro like (defmacro cur-ns [] `(str ~*ns*)) splices the live *ns* value
into its expansion, leaving an opaque jns object as a list element. The
analyzer had no way to carry a runtime value and threw uncompilable — the last
remaining corpus crash. Recognize a jns via the host contract (form-ns-value?)
and emit a :the-ns leaf that reconstructs it by name (intern-ns!) at the call
site, the same IR-leaf pattern as regex/inst/uuid. Closes unquote-*ns*-in-
template; corpus crash count -> 0.

A namespace fast path rather than a general constant pool: it's the only
embedded-value case in the corpus and the common real-world one (libs splice
~*ns*). A general pool can come later if other value types appear.

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.
