Refactoring an Existing Codebase: Understand First, Then Change
What this scenario solves
You inherit undocumented legacy code where one change breaks three things, so nobody dares touch the core logic.

What you end up with
An architecture map and risk list first, then small refactoring steps, each covered by tests and a revertable commit.
