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.
