There was another story, I think on Sufficient Velocity, where it turned out Ragnar Station was a pre-unified/pre or parallel cylon AI that was meant as a deadhand against the Cylons, if the Colonies lost the First Cylon War. It was a black project from IIRC Picon.
Unfortunately, a bunch of dumbass pirates and scavengers activated it during the period between the end of the First War and the Plan, so when the Colonials finally realized what'd happened from new messages coming in on old communication relays and from buried paper books, it was too late. They were panicking, trying to hunt it down before it kick started another war.
There was now a sentient, autonomous factory out there rapidly harvesting resources deep in the black, producing war materiel, upgrading said war materiel, and preparing to launch a genocidal invasion into cylon space.
Basically, "and on a backwater world, a Commander builds a metal extractor" but in space.
I think it's abandoned, though? It's a shame, since the concept itself is pretty fucking awesome.
I'd have loved to see the cylons' reactions to another AI parallel to their own development basically go Skynet on them. All their advantages, such as cyber attacks? Yeah, they're now on an even playing field. Legions of autonomous soliders? Matched, which maybe even worse for them since Centurions, even the newer models with their 'restraining bolts', are actually sapient.
