 "title": "Anthropic RSP v3.0 rewrite adds risk reports and roadmaps; policy text does not name cyber",
 "lane": "policy",
 "kind": "framework",
 "summary": "Anthropic replaced its Responsible Scaling Policy with version 3.0, introducing Frontier Safety Roadmaps and Risk Reports and restating capability thresholds alongside recommended industry-wide mitigations. The published v3.0 policy document does not mention cyber capability; cyber safeguards for later models (Mythos, Fable 5) were described in separate announcements. Versions 3.1 through 3.4 followed between April and July 2026.",
 "whyItMatters": "Researchers tracking how labs gate cyber capability should note that Anthropic's cyber gating in 2026 ran through deployment decisions and classifiers rather than a written RSP cyber threshold.",
