Yogthos 75f6bc79d1 data.priority-map: deftype interop fixes (rseq, arity-overload, empty, Sorted)
data.priority-map's whole suite passes (4/4). It leans on deftype/collection
interop jolt got wrong; four general fixes:

- rseq dispatches to a deftype's clojure.lang.Reversible.rseq method instead of
  always demanding a vector/sorted-coll (natives-seq.ss).
- a deftype method declared at two arities from two interfaces now dispatches by
  arity: the priority-map has seq[this] (Seqable) and seq[this ascending]
  (Sorted), so (.seq pm false) must reach the 2-arg one. find-method-any-protocol
  now matches the call's arg count via procedure-arity-mask, and a deftype's own
  declared method wins over the generic collection interop in dot-forms.
- (empty x) on a deftype/record with its own empty method uses it rather than
  returning {} (jolt.host/jrec-method? gate in clojure.core/empty).
- clojure.lang.Sorted (comparator / entryKey / seqFrom) works on jolt's
  sorted-map/set, so subseq/rsubseq run — including the priority-map delegating
  .comparator to its backing sorted-map (dot-forms.ss + host-static.ss).

Listed in docs/libraries.md + the site. One re-mint (clojure.core/empty);

Clojure libraries known to work with Jolt

Libraries confirmed to load and pass their conformance checks on Jolt. A library listed here works. See the examples, e.g. the ring-app example.

  • aero — EDN configuration with tag literals (#ref/#env/#or/#profile/#long/…)
  • config — environment configuration
  • Selmer — Django-style templates
  • medley — collection utilities
  • cuerdas — string manipulation
  • ring-core — via :deps/root "ring-core", on the ring-app example
  • ring-codec — URL/form encoding
  • ring-defaults — the standard middleware stack (params, static resources + content-type, session, security headers); its session/CSRF crypto comes from jolt-lang/jolt-crypto (OpenSSL)
  • reitit-core — data-driven routing; the reitit.Trie Java class is mirrored by jolt-lang/router.
  • integrant — data-driven system configuration (#ig/ref), with its dependency and meta-merge deps
  • honeysql — SQL formatter and helpers
  • clojure.jdbc — as jolt-lang/db's jdbc.core, over the built-in SQLite access (libsqlite3 via Chez's FFI)
  • next.jdbc — a compatibility layer in jolt-lang/db over jdbc.core
  • tools.logging — runs verbatim over a native clojure.tools.logging.impl stderr backend
  • migratus — database migrations over the next.jdbc layer
  • malli — data schema validation, on the malli-app example.
  • markdown-clj — Markdown → HTML, on the markdown-app example
  • hiccup — HTML from Clojure data, on the hiccup-app example
  • clojure.data.json — JSON reading and writing
  • clojure.spec.alpha — data specs
  • core.match — pattern matching.
  • core.cache — caching (Basic/FIFO/LRU/ LU/TTL/Soft + the wrapped atom API), over data.priority-map.
  • core.memoize — function memoization over core.cache.
  • core.async — CSP channels and go blocks (<!/>!/alts!, pipeline, mult/mix/pub/sub) on real OS threads.
  • core.logic — relational logic programming (unification, run/fresh/conde, finite domains).
  • math.combinatorics — permutations, combinations, subsets, selections, cartesian products, partitions.
  • core.contracts — programming by contract (contract/with-constraints/provide), over core.unify.
  • data.zip — zipper navigation, including clojure.data.zip.xml; XML parsing via jolt-lang/xml (which now ships clojure.xml/parse).
  • data.csv — reading and writing CSV.
  • data.codec — base64 encode/decode over byte arrays.
  • data.priority-map — priority maps (incl. keyfn / custom comparator), with subseq/rsubseq.
  • test.check — property-based testing (generators, quick-check, shrinking).
  • tick — date/time over Jolt's java.time; #time/… literals via time-literals.
  • transit-jolt — Transit (JSON) read/write
