Sorry, I don't get it.
The rule is certainly valid as it compiles and executes fine on Drools.
There may be other instances of "InternalResultCode" just not with these
values.
The values used are binded outside the not() and not used in the rest of
the rule.

I haven't implemented anything. I rely solely on Drools to properly handle
facts and it does so as expected.

That is understood. The RHS of the rule logicalInserts three different
kind of facts, but only two of them are reported as inserted. Where did
the third one go, since the RHS is executed?

Changing Drools version is not feasible at the moment, although at the
TODO list.

Thank you for your time,
