• Fang et al. (ArXiv:2508.07407): the most comprehensive survey of self-evolving AI agents, 1740+ GitHub stars
• VSM mapping: self-evolving agents have strong S1 (operations), S2 (coordination), partial S3 (evaluation but not process audit), strong S4 (environmental adaptation), and no S5 (identity)
• EvoAgentX: five architectural layers, none addressing identity persistence through self-modification
• Liu et al. (ICML 2025): 'Truly Self-Improving Agents Require Intrinsic Metacognitive Learning' — closest ML paper to S5, still not identity
• Strata/CSA survey (285 professionals): only 28% can trace agent actions to humans, only 21% have real-time agent inventory
• Diagrid (Jan 2026): six failure modes all rooted in absent agent identity — no cybernetics citation
• Kellogg (Jan 2026): explicit VSM-to-agent mapping, identifies S5 as the missing piece
• NIST AI Agent Standards Initiative (Feb 2026): three pillars, zero self-governance mechanisms
• Convergence without citation: 7+ independent projects arriving at the same diagnosis without a shared framework
• The bridge offer: ML has the best S1-S4 ever built; cybernetics has the theory for S5. Neither can solve this alone.
