In case this is helpful to contrast your own work, here is the Mill tool chain assembler output for Hello World on the Copper configuration. It is two bundles here because Copper is slot-limited on the flow side; on Silver or Gold it is the same instructions but only one bundle.

Reminder: Mill conAsm is really C++; this file is compileable by Clang/LLVM given appropriate #include’s.
