Yogthos a83ff6ce40 core.contracts: fully passes, two general fixes
clojure.core.contracts (over core.unify) now runs its whole suite on jolt —
14/14 across contracts/constraints/with-constraints/provide tests. Two general
gaps fixed:

- Symbol and Keyword now report IFn (and Fn/Runnable/Callable) in the modeled
  class hierarchy, so a (class x)-dispatched multimethod with an IFn method
  matches a symbol or keyword, like the JVM (both implement IFn — they're
  callable). core.contracts' funcify* dispatches on (class constraint) and a
  bare predicate symbol must hit the IFn arm. Runtime, no re-mint.
- A live Var value spliced into a form by a macro (defcurry-from resolves a var
  and emits (~v l r)) now compiles: analyze treats a var-cell form as a
  :the-var reference by ns+name, the same node as (var ns/name), mirroring the
  existing spliced-namespace (~*ns*) case. analyzer.clj + host-contract.ss,
  re-mint (prelude stays byte-identical; only the analyzer image changes).

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.
