The paper details the design principles and code implementation of each component, contrasts with simpler alternatives, and offers practical guidance for developers to maintain state machine simplicity while ensuring proper browser history support.

This paper provides an in-depth analysis of strategies for safely reverting multiple commits that have already been pushed to remote repositories in Git version control systems. Addressing common scenarios where developers need to recover from erroneous pushes in collaborative environments, the article systematically examines two primary approaches: using git revert to create inverse commits that preserve history, and conditionally using git reset --hard to force-overwrite remote branches. By comparing the applicability, risks, and operational procedures of both methods, this work offers a clear decision-making framework and best practice recommendations, enabling developers to maintain repository stability while flexibly handling version rollback requirements.
