I think these two problems could be solved with the same design. Make the attributes table generic
and give any object you want to "Factify" and add a foreign key to that table.

Then, you can create arbitrary rules for fact summation. For example, a system's facts are the union of

the system + the org + the environment

Or something like that

IMO this design (as it is now) is not easily exportable to other projects since its basically a single AR model and some FKs
