Description
how swap! on atoms work:
get the value of the atom as it is right now
compute the new value it will be after applying the function
if the underlying atom's value is still the same as when we started, "commit" the new value to it. If the underlying value has changed, need to rerun the function on the new state

Research direction
Use the issue description as the starting point: it identifies atom reads, applying the function, comparing the current value, committing, and retrying after a change. Document how swap! follows this sequence and clarify what happens when the atom changes during computation. No file, test, or documentation entry point is named in the payload.
