Yes, this is precisely what the tool knows, and is not reporting.

Yes. Yes. Yes.  Please.

If what the tool is doing is measuring discrepant checksums, then that 
is the good solution.
That is what it knows, but it is not reporting it.

If it reports the checksum for each arch then we can know where the 
discrepancy is located.

The diff itself could also be useful but in some cases might be 
unmanageable. A fragment of the full diff might still be useful, say the 
first 40 or 100 lines, which would avoid the risk of bloated diffs in 
the report.

But in any case identifying the arches involved (reporting checksums) is 
absolutely crucial.
