Two fixes, pick one

Two plausible approaches and no strong feeling about either.

I have two ways to fix this. Compare them on correctness, on what each one makes harder later, and on how obvious each is to the next person reading it. Then pick one and commit to it. I do not want a balanced summary.

Option A:


Option B:

Refactoring and design calls. Cutting code down, naming things properly, and choosing between two workable options.
