A release/optimized `jolt build` is a closed world: every app def is final, so an app->app call can bind to the def's Scheme binding directly instead of going through (jolt-invoke (var-deref ns name)). The emitter gains a direct-link mode (off for the seed mint, runtime -e/repl, and dev builds). With it on, a top-level app def also emits a binding jv$<ns>$<name> that def-var! aliases; an app->app call or value-ref to a name already emitted in the unit lowers to that binding, skipping both the var-table lookup and the generic IFn dispatch. ^:dynamic/^:redef defs and nested defs (a defonce's inner def) opt out and stay indirect. Off direct-link mode, emit-top-form is exactly emit, so the seed and runtime eval are byte-unchanged (selfhost holds). build.ss turns it on for release + optimized; the defined-set accumulates across the dependency-ordered namespaces so a dep's defs are linkable by the time the entry that calls them is emitted. App->core calls stay indirect for now (core is the baked seed); that's a later stage. ~1.74x on a hot cross-namespace call loop (26.5s -> 15.2s). |

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.
