 How it works: at `FN_REQUIRE` the bridge enumerates the module's method names and
 registers each as a class method whose closure proxies `oObj:<name>(args)` to Node
-(mirrors the C++ `TFNModule` `hb_clsAdd(clsH, NAME, DISPATCH)`). Args are native PRG
-values (string/number/hash/array → JS); the result comes back as string/number/
-boolean/buffer(base64)/json. `__end__()` frees the node-side handle.
+(mirrors the C++ `TFNModule` `hb_clsAdd(clsH, NAME, DISPATCH)`). Type conversion is
+two-way: PRG args (string/number/logical/hash/array) → JS; JS results →
+string/number/boolean/buffer(base64), and **JS arrays/objects decode to native PRG
+arrays/hashes** (recursively) — so `Len(oOs:cpus())`, `aCpus[1]`, `hb_HGetDef(h,"k")`
+all work. `__end__()` frees the node-side handle. Multi-type example:
+solmade `app/api/sysinfo.prg` (`os.hostname/uptime/cpus/loadavg/userInfo`).
 - Setup: a `node/` dir with `package.json` + `npm install <pkg>`; the bridge points
   `NODE_PATH` there (default via env `SOLMADE_NODE_DIR`).
 - One persistent `node` per process; calls serialized; pure Go, node spawned on first use.
