Yogthos b4d9eaa527 Read an unknown #tag as a tagged-literal value 
An unknown reader tag produced the reader's internal form
{:jolt/type :jolt/tagged :tag :#foo :form bar}, which tagged-literal? didn't
recognize and which leaked as a raw map when printed:

  (tagged-literal? (read-string "#foo bar"))  => false   ; want true
  (pr-str (quote [#foo bar]))                 => "[{:jolt/type :jolt/tagged ...}]"

Both the data path (rdr-construct-tag) and the compile path (emit-quoted) now
build a real tagged-literal for a tag with no registered reader, like Clojure's
*default-data-reader-fn*, so tagged-literal? / :tag / :form / printing all work.
clojure.edn reads raw forms through a separate __read-form-raw path and applies
:readers/:default itself, so it is unaffected.

Re-mint (backend + reader are seed sources); prelude byte-identical, image only.
make test green (selfhost holds, 0 new/stale), +2 unit 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.
