resolve-sym's last resort silently resolved any unknown Clojure symbol
against Janet's root environment — leaking Janet builtins with JANET
semantics into Clojure code: (type 1) was Janet's :number, (gensym) returned
Janet symbols (the long-documented (symbol (str (gensym))) macro landmine
existed BECAUSE of this), compare/slurp/int?/any? likewise. The explicit
janet/ prefix is the deliberate interop channel; the implicit fallback is
gone — an unresolved symbol is an error.
What the leak was masking, now proper interned vars:
- gensym: jolt's own (already existed, never interned) — returns real jolt
symbols; the macro landmine is dead
- compare: full Clojure total order (nil-first, numbers, strings, keywords,
symbols by ns/name, booleans, chars, uuid/inst, vectors by length then
elementwise; cross-type throws)
- type: :type metadata override, deftype/record tag as symbol, else a
taxonomy keyword (host-classified)
- int?: core-integer? — which had a latent bug the leak hid: (integer?
##Inf) was true (floor of inf is inf); NaN/infinities now excluded
- any?: constantly true (Clojure 1.9; SCI's namespaces.cljc needs it)
- jolt.interop/janet-type now uses the explicit (janet/type x) channel
- evaluator-test uses init (a bare make-ctx resolved EVERYTHING via the leak)
Suite 4470 -> 4532+ pass / 86-87 clean (proper compare unlocks the sort
files); baselines raised. Conformance 326x3 (+5 rows), +22 predicate spec
rows, stdlib battery green, all specs+unit. Coverage dashboard now counts
previously-leak-resolvable names honestly (missing-portable 19 -> 27).
