No mature Chez fibers library exists and this is a threaded Chez build, so a go block is an OS thread and a channel is a mutex+condition blocking queue: <! / >! are the blocking <!! / >!! and work anywhere (no CPS transform), like the Janet stackful-fiber model but with real parallelism and a shared heap. host/chez/async.ss provides chan (unbuffered rendezvous / fixed / dropping / sliding), <! >! <!! >!! close! alts! timeout put! take! buffer ctors, channel transducers, and go-spawn, all def-var!'d into clojure.core.async; go/go-loop/ thread are macros (mark-macro!) expanding to go-spawn, mirroring src/jolt/ async.janet. Binding conveyance rides the thread-parameter binding stack from pt.1. alts! polls with a 1ms backoff (no cross-channel wait-set yet) and is take-only, matching the Janet impl. (require '[clojure.core.async ...]) resolves it with no file load — the vars are resident and require just registers the :as/:refer. cli-test covers go/buffered-drain/nested-<!/alts!/transducer/timeout/binding- conveyance (43/43). core.async isn't in the conformance corpus (feature-gated :async/core-async), so coverage is the Chez cli-test plus the existing Janet core-async-spec. Seed unchanged (no .clj touched). Prelude corpus 2534->2559, zero-Janet 2569, 0 new divergences on either; Janet gate + JVM cert green. jolt-byjr
