What's the 'local package cache'.

A 'local package' would have a pathname as the 'repo url'.

A cached package should have a download/cache entry in the log.

Right, "to figure out how some file came into the system" is the main
purpose of the log.


Btw, a proper log would also need a 'rpm database changed' callback
from libzypp if the @system.solv file needs rebuild.
An external program could then log package changes based on comparing
@system.solv (old known state) and the rpm database (new state).
