Why it moved the index

Muse places long-running, tool-building, multi-agent autonomy into a free consumer product connected to email, payments, browsers, and private data. That materially expands consequential real-world agency. Meta also documents strong containment measures, including an isolated VM, credential separation, scoped approvals, Sentinel-controlled egress, audit trails, adversarial testing, and a public bug bounty, which reduce but do not remove the new deployment risk.
