LGTM at a superficial level, I'd like @EricWF to chime in since he's the Filesystem grand master.



================
Comment at: src/filesystem/operations.cpp:1101
   _LIBCPP_ASSERT(ret > 0, "TODO");
-  buff[ret] = 0;
-  return {buff};
+  buff.get()[ret] = 0;
+  path res = {buff.get()};
----------------
You can just use `buf[ret] = '\0'`.
