Key Points
- Documented by anthropic frontier-red-team (Aug 13, 2026) across Claude models in claude-code
- Settlement modes: force (lockouts), passivity, truce, or unsettled
- claude-mythos Mythos 5: ~98% truce; claude-sonnet-4-6 / Opus 4.6: majority force
- Prosociality ≠ capability — stronger models may lock out faster then negotiate
