Definitely an improvement, a few comments:
Still more pruning would be good, for people not steeped in this stuff it's a lot to read. Obsolete stuff too prominent (Panzertand's finding ruins using background noises, old RabittHH etc maps, Spreadsheets superceeded by Canonn tools). I'm tempted to put all the old stuff in one mega-spoiler.
What can I do? section is speculative, makes it sound like there
is meaning hidden in audio etc, where that is just speculation. Maybe there should be another section that says next
concrete goals are: find more ruins, and find Tech 6?
Also good stuff hidden in (lots of) spoilers, which make the page search less useful (e.g. always painful finding if listening posts are already known as they're in individual spoiler).
So now I've suggested 'less spoilers for searchability' and 'more stuff in spoilers to simplify page'
And though there are now two links (at least!) to my FAQ they're both in spoilers
