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.
Mirrors test/bench/core-bench.janet's 8 compute programs + methodology (load the
runtime once, time compile+run of each, min of N) so the zero-Janet Chez path is
comparable to the Janet compile path.
Result: Chez is 3-33x faster than Janet across the set (~320ms vs ~5000ms total,
~15x), biggest on seq/map/reduce, smallest on fib (3.2x). So deleting Janet is a
perf win, which satisfies the "perf confirmed" precondition Phase 5 gates on. Chez
is ~2-28x slower than JVM Clojure, expected and not the bar (and the Janet-only
optimizing modes haven't been tried on Chez).
