refactor-one-function.txt
Here is one function: <paste>

It works. I don't want new behaviour — I want it easier to read.

- Same inputs, same outputs, same side effects.
- Tell me first, in two lines, what makes it hard to read.
- Then the rewrite.
- Then list anything the rewrite changed that I should test.

Do not touch anything outside this function.

"Refactor this" with no boundary is an invitation to rewrite your project. One function, stated behaviour, explicit limits.
