Yogthos 09a9ad8c75 Add bigdec min/max (review follow-up) 
Review found (< 1M 2M) worked but (min 1M 2M) threw — incoherent. Wire min/max
the same way as the other ops: value-position jolt-min/jolt-max shims (new in
seq.ss, added to core-value-procs) and call-position via bd-spec/bd-ops ->
jbd-min/jbd-max.

min/max return the original operand by value, not a coerced copy, matching
Clojure: (min 1M 2.0) -> 1M, (max 1M 2.0) -> 2.0, (min 1.50M 2M) -> 1.50M; a tie
keeps the second operand ((max 1.5M 1.50M) -> 1.50M). bigdec mixed with a flonum
in call position stays in the documented :any/contagion gap (value position
handles it). Re-mint; 6 more JVM-certified rows.

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.
