A direct-link build emits (jolt-register-source! short-name ns name file line) once per fn def — at definition time, so zero per-call cost. On an uncaught error the reporter walks Chez's native continuation frames (jolt-throw captures the live continuation via call/cc; host conditions carry their own &continuation), maps each frame's procedure name through the registry, and prints a Clojure backtrace 'ns/name (file:line)'. Wired into both the cli and a built binary's launcher. Frames are keyed by the short munged fn name Chez actually reports (emit-fn's letrec self-binding), not jv$ns$name; a cross-namespace collision degrades to the bare frame name rather than a wrong attribution. The analyzer carries the original form's position through defn macroexpansion onto the def node. Calling a non-fn now throws a catchable ClassCastException (via jolt-throw) naming the operator, instead of a raw Chez error. Caveats (documented in source-registry.ss): names map only in direct-link/AOT closed-world builds — the open-world -e/repl/run path falls back to the top-level location; and pervasive TCO erases tail-call frames, so a mapped trace shows only the non-tail spine. JOLT_DEBUG_FRAMES dumps raw frame names. Re-mint (analyzer + backend); prelude byte-identical (direct-link off during mint). Corpus rows certified, build-smoke asserts the trace. |

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.
