Yogthos 135bad9d3a edn: read raw forms so a #tag goes through :readers/:default 
clojure.edn/read built the built-in #inst/#uuid eagerly (via read-string), so a
:readers override couldn't win and #inst applied to a non-string form (aero's
#inst ^:ref […]) threw. Read the raw form instead and let edn->value route every
tag through :readers then :default then the built-in — matching clojure.edn,
where a reader from opts wins. edn->value now also converts the (recursively
converted) metadata, since the raw path skips the read-string data seam. aero
suite: 59/0/0 (full pass). clojure.edn baked, re-minted.

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.
