Nexoniarz b6450d866d docs: a footer note on building with AI
The point is not a disclaimer, it is the argument: the tool is not the measure
of a project. Code nobody understands is bad code whoever typed it, and code
whose every decision can be explained is good code by the same standard.

Placed next to a link to history/ on purpose. That directory is where the
claim can be checked -- the bugs are written up in full, including the wrong
hypotheses and the measurements that killed them. An explanation you can
follow is the evidence; a byline is not.
