Yogthos 70d52ae704 Split the success-checker out of types.clj
types.clj held the inferencer, the success-type checker, and the driver in one
716-line namespace. Move the self-contained checker into jolt.passes.types.check:
the error-domain predicates (not-number?/not-seqable?/not-callable?), the op
tables, type-name, check-invoke, and the user-fn registry. These are pure over
inferred types and the run's env cells, with no inference, so a check-rule edit
can no longer perturb the inferencer.

The infer-coupled probes stay in types.clj — isolated-diag-count and
check-user-call re-run inference, so moving them would make check depend on the
inferencer and reintroduce the cycle. Verbatim move; new ns wired into
ei-compiler-ns-files; seed re-minted to the byte-fixpoint.

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.
