In general, no, but sometimes, yes, or at least linked from the commit the same way user stories/issues are. Admittedly the 'sometimes' from my perspective is mostly when there's a need to educate fellow humans about what's possible or about good prompt techniques and workarounds for the AI being dumb. It can also reveal more of x% by AI, y% by human by for example diffing the outputs from the session against the final commits.
