调研方向

Start by reviewing the historical sample3.py and patch_1.diff linked in the issue, then locate the current argparse conflict-resolution implementation and its tests. Reproduce the parent-parser behavior described in the title and verify that resolving a conflict no longer damages the parent actions, with regression coverage for the case.
