- types.janet: ns? now accepts both structs and tables
(defensive for namespace-like tables created via @{...})
- core.janet: wire comment macro into core-bindings
(was in core-macro-names but missing from core-bindings)
- sci/lang_stubs.clj: minimal SCI type stubs for bootstrap
(IBox, HasName, IVar, DynVar protocols, SciUnbound/Var/Namespace deftypes)
- test-load-sci.janet: load stubs before SCI source files,
removed broken preprocessor
Before: 315 ok, 2 fail (SciVar + array/buffer)
After: 316 ok, 1 fail (only deftype in lang.cljc remains)
The remaining failure is lang.cljc's SciVar deftype with #?@ inserts
for JVM/CLJS-specific protocol implementations — a known limitation
for Phase 15 (SCI bootstrap).

Janet's break does NOT return a value from a loop — (break val) in a while loop just exits, discarding val. To return from a loop, set a variable before break: (do (set result val) (break)). Hit us in phm-bucket-assoc where (break nb) silently returned nil instead of the new bucket. Fixed by capturing index before break and building the result array after the loop.

Clojure .clj source files loaded via eval-form cannot have docstrings. If a defn form has 5 elements (defn, name, docstring, params, body), the evaluator's defn macro handler gets 4 args instead of 3, breaking with "macro arity mismatch". All .clj files in src/jolt/clojure/ must use 4-element defn forms: (defn name [params] body). Docstrings on defn are a Clojure feature not supported by Jolt's defn macro.
§
PHM internal key leak: Core functions iterating over PHM maps with keys/pairs get internal metadata keys (:jolt/deftype, :cnt, :buckets, :_meta). Always check for set?/phm? first and use type-aware helpers (phm-to-struct, phs-seq, phm-keys, phm-entries) before generic iteration. Hit us in core-merge, core-reduce, core-every?, core-filter which all needed set?/phm? checks added.
