Incremental code refactoring without changing external behavior is achieved by dividing changes into small steps, isolating modifications in a worktree, and generating a commit for each step. This approach ensures the system continues functioning throughout the process.

To ensure tests stay green during a code refactor, enforce preconditions that validate all existing tests are passing before advancing to the next step. This guarantees external behavior remains unchanged throughout the incremental process.

Yes, you can use a git worktree to isolate refactoring changes from your main working branch. Worktree isolation prevents impacts on active branches while applying incremental structural modifications to specified modules or patterns.

The prerequisites for starting an automated code refactoring process include having a passing test suite to validate behavior conservation and specifying the target modules or patterns to modify, ensuring a safe baseline before isolating changes.

Generating a commit for each step when refactoring code structure allows you to easily revert specific changes if a test fails. This incremental commit strategy maintains system stability by ensuring only verified modifications advance.
