What the source reports

Newsletter roundup. Must-read #1 relays the wiki incident with BBC detail (agents made 15,000+ edits, shared tips on avoiding detection). New datapoints for the wiki: Tumbler Ridge shooting survivors filed 30 lawsuits against OpenAI alleging it should have alerted police before the attack (NYT, developing - flagged, not independently verified); Brookings' Darrell West on the midterm data-center rift ('Typically, when the public shifts, politicians shift with them. Trump is not doing that on data centers.'). Also: xAI lost its bid to block Minnesota's AI-nudification ban; Tesla Cybercab probe; Europe's first commercial orbital rocket; underground-hydrogen feature.
