corpus.edn :expected is now the value reference JVM Clojure produces, set by the
new test/conformance/regen-corpus.clj (one JVM process, per-row thread watchdog).
167 rows moved to the JVM value: ratios (/ 1 2)=>1/2, doubles (double 3)=>3.0,
shared-heap concurrency (the future/pmap/agent cases), clojure.math doubles. The
JVM is the spec; jolt is measured against it.
known-divergences.edn shrinks to the rows whose JVM value is an opaque host object
that can't round-trip to source (Java arrays, transients, atoms, beans, proxies,
chunks all print as #object[..@addr]) plus (fn* foo) and a few racy concurrency
cases (:flaky). The zero-janet gate's allowlist becomes the set of host gaps vs the
JVM spec (no Class/array/BigDecimal, :jolt reader, jolt's own printing).
Math/clojure.math sqrt/pow/floor/trig now return doubles (Chez returns exact for
exact args, e.g. (sqrt 9)=>3); JVM always returns a double.
extract-corpus.janet no longer writes corpus.edn unless asked (the test runner
imported it and was silently overwriting the JVM corpus with the spec sources'
placeholder answers). The prelude parity gate is deleted — the zero-janet spine +
certify.clj are the oracles.
zero-janet 2678 (0 new divergences), certify 0 new / 0 stale, emit-test 330/330.
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.
