set/hash-map/hash-set/array-map/rand resolved to jolt-nil on the prelude (the apply-jolt-nil crash bucket) — the pmap/pset ctors already existed in collections.ss, just bind the public clojure.core names to them. Map entries are now a distinct type: a pvec carries an ent flag (default #f), so an entry equals its [k v] vector and walks like one (nth/count/seq/=/hash/ print read only v) but is not vector? and is map-entry? — matching Clojure's MapEntry. seqing a map produces flagged entries; vector? excludes them. This unblocks key/val (overlay fns gated on map-entry?) and the every? map-entry? cases. Prelude parity 1534 -> 1593, 0 new divergences. jolt-agw6.
