Meta shipped Muse on September 8-9, 2026 — a 24/7 personal agent for iOS, Android, web, and WhatsApp, built on Muse Spark 1.3. What makes it worth a deep read isn't the assistant pitch, it's the security architecture behind it: a per-user Secure VM, a Sentinel agent that brokers every network request, eBPF-based taint tracking, and a public bug bounty paying up to $130,000 for a working prompt injection.
