This is something that I struggled with as well. Back before Jupyter was a big thing I wrote a system called bein (https://github.com/madhadron/bein) that promoted the individual execution to the primary artifact instead of the source code, since that's usually what data analysis and other computational science work really cares about.

Based on my intervening (looks at git timestamps) decade of thinking, I would probably approach it differently, but I think that key point of execution as the artifact and wanting to trace its provenance instead of wanting to track source code remains correct.
