Restores the standalone-binary capability the Janet host had. `bin/joltc build -m NS -o OUT` AOT-compiles an app into a single self-contained executable — the whole runtime, clojure.core, stdlib and compiler embedded, no Chez install or jolt source needed at runtime. Pipeline (host/chez/build.ss, host primitive jolt.host/build-binary driven by jolt.main's build command): resolve deps, load the entry namespace recording the app namespaces in dependency order, re-emit each to Scheme, textually inline the cli.ss runtime load sequence into one flat source + the app + a launcher, then compile-file -> make-boot-file -> embed the boot as C bytes -> cc-link against libkernel.a. Two non-obvious bits: the compile pass runs in a fresh Chez, not the loaded runtime (regex.ss shadows top-level `error`, which otherwise bakes a broken reference into the boot); and the launcher installs scheme-start rather than running -main at top level, since boot top-level forms execute during heap build before argv is set, so args only reach -main through scheme-start. Loader: a require of an in-memory namespace with no source file now no-ops, so AOT'd app namespaces satisfy require in a built binary. Mode flags (--opt/--dev, default release) are plumbed; the optimization passes they gate come in a later stage. RFC 0007 has the design. Gated by `make buildsmoke`. |

Chez test harness
The correctness gate for jolt. Pure Chez (+ Clojure for the JVM oracle).
Correctness is judged against the JVM-sourced conformance spec; the spec itself
lives in test/conformance/ (see its SPEC.md). Run the whole gate with make test from the repo root.
The spec corpus
corpus.edn is the contract: ~2920 rows {:suite :label :expected :actual}, with
:expected sourced from reference JVM Clojure by test/conformance/regen-corpus.clj.
It is frozen (the canonical source) — add or change cases here, then re-source the
answers with regen-corpus.clj and re-certify with test/conformance/certify.clj.
The gate runners (host/chez/)
-
run-corpus.ss— runs every corpus case through the spine (read → analyze → IR → emit → eval, all on Chez), comparing each result by value-equality against the JVM:expected. Aknown-failallowlist covers cases jolt can't match because Chez has no JVM host (Java classes, arrays,BigDecimal, opaque host-object printers, …); the gate fails only on a NEW divergence or if the pass count drops below the floor.chez --script host/chez/run-corpus.ss JOLT_CORPUS_LIMIT=200 … # every-Nth stride, fast iteration JOLT_CHEZ_ZJ_FLOOR=N … # override the floor (default 2678) -
run-unit.ss— host-specific unit cases (test/chez/unit.edn) that aren't in the JVM-portable corpus: dot-forms, java statics, io, reader, walk, vars/namespaces, refs. Each:expris evaluated in-process and its printed value compared to a baked:expected(:throwsasserts a raise). -
selfcheck.sh— self-host fixpoint:bootstrap.ssrebuild byte-equals the checked-in seed (host/chez/seed/). -
smoke.sh— realbin/joltc -eCLI smoke.
Other Chez tests
values-test.ss— the value model (nil/truthiness/collections).make values.bench-chez.ss— compute bench through the pipeline (opt-in; not in the gate).
All runners assume chez on PATH.
