Yogthos d1c2811d13 *in* is a Reader, not a map 
(map? *in*) was true because *in* was a plain map of read-line-fn/read-fn
closures; the JVM *in* is a java.io.Reader so map? is false. A defrecord
doesn't help (records are maps). Make the reader a reify over a new IReader
protocol — a non-map value — and route read/read-line/read+string/line-seq
through its -read-line/-read-form/-read+string methods instead of keyword
access. with-in-str's __string-reader and the stdin *in* both reify it.
Closes *in*-bound + *in*-is-bound.

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.
