Muse Glimmer 30B, Docker Sandboxes, and 180,000 Leaked Meetings

Meta opens its first Apache 2.0 agent-first model, Muse Glimmer 30B, built for always-on local workflows and distilled from Muse Spark. Docker ships disposable microVM sandboxes so agents run unattended without touching the host. A researcher shows tl;dv's Firestore database exposed 181,874 meetings to any authenticated user, six months after his disclosure went unanswered. Plus: Claude improves a Riemann zeta bound from 41.6% to 67.2% with a formally verified proof, and OpenAI gates GPT-5.6-Cyber behind Daybreak Red.
