A File is a path-backed jfile record: (instance? java.io.File f) is true, str/slurp coerce it to its path, and the File method surface (getName/ getPath/exists/isDirectory/isFile/listFiles/getParent) dispatches through record-method-dispatch. slurp/spit/flush run over Chez's filesystem primitives; file-seq's dir primitives (__file?/__dir?/__list-dir) and the overlay's File branch (.isDirectory/.listFiles, which emit to jolt-host-call) are jfile-aware. clojure.java.io/file + as-file are def-var!'d natively. New host/chez/io.ss, a Chez-native implementation -- the seed's clojure.java.io (io.clj) is a Janet-backed shim over janet.*/janet.file, so it can't be reused. The analyzer resolves io/file because the seed ctx has clojure.java.io loaded; only a runtime def-var! is needed. type/instance- check/str-render/jolt-host-call are extended via the set!-wrap pattern (type also re-def-var!'d since the var cell captured the old value). Reader/StringReader-coupled io (io/reader, line-seq over a file, .toURL, slurp over a reader) deferred to jolt-at0a. Parity 2176 -> 2191, 0 new divergences. New test/chez/_io.janet 20/20.
