Having an honesty based tag could be only way to monitor impact or get after a fix in code bases if things go south.

That is at the moment: - Nobody knows for sure what agents might add and their long term effects on codebases.

- It's at best unclear that AI content in a codebase can be reliably determined automatically.

- Even if it's not malicious, at least some of its contributions are likely to be deleterious and pass undetected by human review.

it makes sense to keep track of what model wrote what code to look for patterns, behaviors, etc.

It isn't?

They mention an Assisted-by tag, but that also contains stuff like "clang-tidy". Surely you're not interpreting that as people "attributing" the work to the linter?
