Yogthos 14ce46fb2a defn docstrings, assert throws AssertionError, Seqable covers collections 
Conformance gaps surfaced re-running the library suites:

- defn now keeps a leading docstring as :doc metadata — it was dropped, so
  (:doc (meta #'f)) was always nil. Rides the def docstring slot.
- assert (and :pre/:post) throw a real AssertionError instead of an ex-info, so
  (catch AssertionError …) / (thrown? AssertionError …) match, with Clojure's
  "Assert failed: <msg>\n<form>" message.
- instance? clojure.lang.Seqable was conflated with ISeq, so a vector/map read
  as not-Seqable. Split them: Seqable covers every persistent collection, ISeq
  only seqs.

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.
