There are several possibilities. The most likely, IMHO, is a list of special (i.e., with MAlign crews) freighters and couriers, which could be a clue for Silver Bullet (the special MAlign drones that were inserted into the Beowulf to destroy the Mycroft command nodes). For that matter, there could be other references to Silver Bullet (the delivery went through Warner after all and from Darius, not Galton, which could be a clue for Darius’s existence). Another possibility are references to the ships used for Operation Houdini. If Director Harris was in direct communication with Darius (IMHO, known MAlign security protocols would forbid this), the fact that it was about 10 light years from Mannerheim (which means that a wormhole, either bridge or junction, was about 10 light years from Mannerheim) would be apparent. She probably was in communication with Galton, which would have reinforced Anton’s conclusion on the destination of all those slave ships.
3) Could the other data found at Warner-Mannerheim Bridge hint at Darius?
The most likely scenario is that it indeed had clues to ships departing for Felix, especially recently with Houdini's execution..
Old data about the colonisation of Darius was probably not there at all. It would have been scrubbed a long time ago since it didn't need to exist any more. Even if there were corrupt middle management trying to extort the company, they wouldn't be using 150-T-year-old records.
A discrepancy I've noticed in how the RF is described is that it was a regional grouping... but we know Visigoth, a member of the League, was supposed to be one and it isn't close to Mannerheim or Warner. So my guess is that Visigoth hasn't declared its membership yet. Which in turn means the Mannerheim-Warner bridge office probably had records of excess of traffic between Mannerheim and Visigoth.
4) Will Anton and company find anything hints of Darius at Galton?
The Detweilers certainly tried to keep the system clean of such clues. The Alamo Option eliminated the handful of people with direct knowledge of Darius (even if they didn’t know where it was). However, there is a possibility that Zach’s contributions to Galton’s R&D will might attract attention when an attempt to find the author fails. Of course, Zach isn’t there (but they can’t exclude the possibility that something happened). It should be possible, using the preserved records of Mesa’s Traffic Control System to identify most, if not all, of the people supposedly killed by various “terrorist attacks” or “accidents” but were actually evacuated by the MAlign. While most went to Galton, some went to Darius. Close questioning of the evacuees (assuming no suicide protocols in place) at Galton might reveal interesting information about the missing (i.e., the ones who went to Darius). By interesting, I mean information that would cause team Anton to realize that the missing were not the victims of random chance.
Zach's content was reviewed and sanitised by others. So it's unlikely that he managed to slip something by them and into the Galton's databases. I don't think Anton & company will find the location of Darius there.
But discrepancies, sure. Darius had been controlling the research in Galton for a long time, both inserting data and curbing lines of research that the Onion didn't want Galton to explore. So for the same reason that they realised that Manpower wasn't operating Verdant Vista with a profit motive, they should realise that someone was controlling the research. The next step from here is not logical by itself: that the entity controlling was actually not present in the system. But if you add to the complete absence of a spider drive debris or research, that leap can be made.
And, as you said, that they'll be able to correlate who was evacuated from Darius with who showed up on Galton. Oh, there'll be gaps: we know some people were intercepted on the way, and the records on Mesa weren't perfect to begin with. But as you say, there'll be just too many missing to be accounted only by external events.
So, yeah, the evidence piles up.
5) How can Darius be found?
Finding the Felix Junction, which won’t be easy, is only the first step. While I don’t remember any mention that the Darius terminus is fortified, I expect that it is (and if it isn’t at the end of _To End in Fire_, it should be heavily fortified within years). Thus, it can not be forced without horrendous expenditure of blood (this isn’t Starfire where a fleet could pump millions of armed drones through a warp point). Finding Darius will require either a breakthrough in the understanding of wormholes (i.e., determining the approximate location of the other end) or an exhaustive survey of star systems that are within a sphere centered on Felix (BTW, the maximum known wormhole length is over 900 light years, that is over 3 billion cubic light years). Fortunately, if the search is done as shells around Felix, then they only have to search a sphere with a radius of 130 light years (the Felix-Darius wormhole is rather short). This will require searching only about 20 thousand star systems (many will have 2 or more stars).
6) Finding the Felix Junction
Besides tracing inadvertent breadcrumbs, it is possible that the Felix junction could be found the hard way. Since, the Galton survey was false, the Solarian League might start the very lengthly process of checking every uninhabited system in the survey database just to see if more bad data had been snuck in. Thus, the Mannerheim taskforce guarding the Felix junction will be faced with a quandary when the survey ship shows up. Destroying it won’t work, because the follow up mission will probably be harder to destroy and then they will be in real trouble. Of course, if a ship transits to Felix from Darius (or “SGC-902-36-G”, the back door to Torch) while the survey ship is in system, then they will also be in real trouble.
Brute-force is impractical. It's a bit less than what you calculated because a radius of 900 light-years necessarily moves off the galactic disk and therefore there are fewer candidate stars, but that doesn't reduce by nearly enough to make practical.
Felix doesn't appear to be a faked survey, unlike Galton. It was just incomplete because the survey ship didn't realise there was a junction there. So the report is actually accurate, as far as the survey ship knew.
The problem for them is that the Mannerheim-Warner bridge has got a spotlight on, which puts a spotlight on Mannerheim. Added to Director Ganon's suspicion of the RF, Mannerheim's ability to protect Felix is diminished. Can they take the risk that someone follow them to see why they keep going for exercises that often?
So, I don't know how Darius or Felix will be found. My wild guess is that the Darius Resistance has a means of communicating off-planet.
PS: I was glad to see Allen Higgins too.
