By the way, here is a really good reason for us to ensure that Cornelia's war goes favorably for her, with getting Docking and Passage Rights and also any additional support that we can feasibly afford to throw her way:
If we can tilt the odds in her favor, getting access and hopefully safer access to the area that is currently contested suddenly becomes much easier. And as in that scenario we will have helped Cornelia in her war-effort, she will likely be more willing to humour us wanting to search and mess around with some ancient ruins without Lelouch explaining everything. In fact, with the recent world-wide revelation about the power of psionics in warfare, just straight up telling her that we are searching for potential psionic artifacts will likely be enough to satisfy her curiosity, and maybe even gain her support for the effort if we promise some of our potential future toys for her army.
So yeah, I think that getting Cornelia more support via a new navy route with docking chances to supply and repair goes over both the trading rights and the noble patent. I might even switch my vote later on to ensure that it wins, if its teetering between the third and fourth place and I'm voting something that is contesting its place.
