Rename src/jolt -> stdlib (the runtime-loaded layer; jolt-core stays the
seed-baked layer) and update the loader / emit-image / doc paths. Drop dead
code: the spike/ experiments, the duplicate clojuredocs-export.edn (json moves
to tools/), the Janet-era jolt.http binding, and the orphaned
persistent_vector.clj whose ns/path didn't even match.
Strip porting residue from comments and docstrings across host/chez, jolt-core,
stdlib, tests, and docs: internal issue ids, "Phase N" markers, and the "vs
Janet" historical exposition, leaving present-tense descriptions and the real
JVM-Clojure semantic contrasts. Same pass over the corpus suite labels. The seed
is unchanged (docstrings/comments aren't emitted), so the self-host fixpoint and
corpus are untouched.
Port tools/spec_coverage.py off the dead janet probe to bin/joltc and regenerate
coverage.md; drop the dead :host/janet rule from certify.clj and regenerate the
conformance profile. Add docs/host-interop.md (the JVM shims and how to register
your own host class from a library) and a writing-style note in CLAUDE.md.
Stabilize the four racy concurrency corpus cases (future-cancel and agent
send/send-off): give the future a sleeping body and the agent a slow action, so
cancel reliably catches an in-flight future and deref reliably reads the
pre-update snapshot. They certify deterministically now, so drop their :flaky
allowlist entries and the orphaned legend.
bigdec / 1.5M / 0.0M silently produced doubles. Add a jbigdec value type
{unscaled, scale} over Chez exact integers (host/chez/bigdec.ss): value =
unscaled * 10^-scale. An M-suffix literal reads to a :bigdec form that the back
end lowers to jolt-bigdec-from-string (same IR-leaf path as #inst/#uuid); bigdec
coerces a number/string. Equality is by value (1.0M = 1.00M true, 3M = 3 false),
str drops the M and pr keeps it, class is java.math.BigDecimal, decimal? is true.
Arithmetic contagion isn't modelled (out of scope). The old corpus cases passed
spuriously as doubles; they now exercise a genuine BigDecimal.
