Right.  Archives are sources of new packages and updates, and should
only be thought of in those terms.  It is complex and not that useful
to reason in terms of which archive did some installed package come

There is also no search term for this, and neither should there be.

Lots of work for a complicated implementation, just to support a
reasoning model which is also complicated and not that useful.
