I'd just say "…is incorrect", as is it repeats the code in the check

Done.

   *reinterpret_cast<uint32*>(buffer->data()) = json.size();
   memcpy(buffer->data() + kMessageHeaderSize, json.data(), json.size());
 
   // Push new message to the write queue.
   write_queue_.push(buffer);

   // message will be written when OnHostProcessLaunched() is called. If it's
   // already started then write the message now.
