The corpus certifier (test/conformance) flagged four cases where jolt's
hand-written :expected matched a real defect rather than Clojure. Fixed in the
jolt-core overlay, corrected the spec :expected, re-certified against JVM Clojure:
- ex-message: returns nil for a non-throwable (dropped the lenient string branch);
still returns the message for ex-info. (jolt-l8e8)
- munge: preserves the argument's type — a symbol munges to a symbol, not a string.
(jolt-hc35)
- print: (print nil) emits "nil", not "" (top-level nil guard; str yields "").
(jolt-pqio)
- bounded-count: uses the counted? fast path (full count), else counts up to n via
seq — was (min n (count coll)), wrong for counted colls. Added an uncounted-coll
spec case. (jolt-2507)
Removed the 4 :bug entries from known-divergences.edn (now certified), regenerated
corpus + profile, re-minted the Chez bootstrap seed (clojure.core changed). Gates:
Janet 155/0, JVM certify clean, both Chez corpus gates 2534 (floors raised),
bootstrap 6/6, fixpoint intact.
Makes the host-neutral corpus a first-class language specification with
conformance levels, not just a regression suite.
- [suite label] is now a unique, stable case id (extract-corpus disambiguates
duplicate labels with ' (N)' — one collision existed).
- certify.clj --profile emits test/conformance/profile.edn: every non-portable
case classified by the host feature it requires (numerics/double-only,
concurrency/snapshot, host/jvm-interop, host/arrays, host/janet,
async/core-async, runtime/eval, reader/jolt, printer/jolt, strictness/jolt,
impl/representation, bug). 2670 of 2919 cases are portable (pass on any faithful
Clojure); 249 are feature-gated.
- SPEC.md documents the contract: row schema, the JVM oracle, conformance levels,
the feature vocabulary, and a worked new-runtime harness — so hosting jolt
elsewhere and proving it correct is read-one-file mechanical.
Janet gate 155 files 0 failed; certify + zero-janet gates green.
