Filling the biggest untested clojure.core areas found in a coverage audit (168 of 506 provided fns had no spec). New + expanded suites: - regex-spec.janet (20): #"…" literals, regex?, re-find/re-matches/re-seq (match/no-match/groups), re-pattern, and clojure.string split/replace with regex (incl $1 backrefs). Whole area was previously unspecced. - sorted-spec.janet (14): sorted-map/sorted-set construction + ordering, sorted?, subseq/rsubseq. Pins the working subset — get/conj/assoc/keys/vals on sorted colls and the by-comparator ctors are not yet first-class (jolt-ti9). - predicates-spec +14: seqable?, integer?, reduced?/unreduced, not-empty. - numbers-spec +5: rand/rand-int/rand-nth invariants. Fix: sorted? was bound to core-sorted-map? so it returned false for sorted-sets; now true for both sorted maps and sets (core-sorted?). Filed: jolt-ti9 (sorted collections incomplete: get/conj/assoc/keys/vals don't operate on the sorted wrapper; sorted-*-by ignore the comparator). Gate green incl full jpm build + jpm test.
