Missing potential biologicals due to not having been seen in region about canonn-signals HOT 2 OPEN

We cannot assume that all biologicals are in all regions because we have seen distinct patterns pegged to spiral arms. So we have to choose between false positives and false negatives or build in some specific logic for that.

I agree that this is a difficult problem to resolve.
I think perhaps it's best to park this for a while.
Work on the false positives and false negatives and see if we can improve the guesses to be quite accurate.
At that point it will be more obvious that this state has been encountered because the FSS scan will show 4 biologicals but the potentials will show only 3.

One option for specific logic might be to pillage the in-game codex for data. Much more data in there about which species appears in which sector than we have in the Canonn database.

Another option would be to add a user-configurable option to enable/disable filtering by region.
