Yogthos c0561a8d14 java.time Phase 1: LocalDate/LocalTime/LocalDateTime/Instant 
Core java.time value types as jolt host objects backed by the inst-time.ss
calendar engine (days-from-civil/civil-from-days/inst-fields/format-ms), in a
new host/chez/java-time.ss. tz-free reps: LocalDate=epoch-day,
LocalTime=nano-of-day, LocalDateTime=(epoch-day,nano-of-day); Instant reuses
the ms-based instant jhost (ms granularity; nano is a documented gap). Each
type registers statics (of/parse/now/MIN/MAX/...), instance methods
(plus/minus/with/get/isBefore/until/toString/...), =/hash, compare,
ISO-8601 print, instance?, and value-host-tags for protocol dispatch.

Reconciles the old ms-based local-date/local-dt stubs into the rich types
(LocalDateTime now prints ISO; .toLocalDate/.atZone paths preserved). The
four cljc.java-time namespaces (local-date/local-time/local-date-time/instant)
load. Deep temporal-field/unit machinery (range/get-long/with-field/until/
adjust-into) stubbed for Phase 2.

12 corpus rows certified vs JVM 1.12.5. make test + shakesmoke green, 0 new
divergences, data.json stays 138/139, selfhost holds.

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. A known-fail allowlist 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 :expr is evaluated in-process and its printed value compared to a baked :expected (:throws asserts a raise).

  • selfcheck.sh — self-host fixpoint: bootstrap.ss rebuild byte-equals the checked-in seed (host/chez/seed/).

  • smoke.sh — real bin/joltc -e CLI 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.
