Current State

test_converter_roundtrip.py already covers the core conversion logic, but it has meaningful gaps:

What is covered

• merge_lora_to_hf() from convert_lora_to_hf.py (called directly via importlib)
• convert_dcp_to_hf() from nemo_rl.utils.native_checkpoint (the underlying library function)
• export_model_from_megatron() from nemo_rl.models.megatron.community_import (the underlying library function)

What is NOT covered

• The CLI entry points of convert_dcp_to_hf.py and convert_megatron_to_hf.py — their parse_args() + main() paths are never exercised
• convert_lora_to_hf.py's own main() is also not invoked — only the inner function is imported
