MARIA VITAL: The Life Support System for Agent Organizations — From Heartbeat Monitoring to Recursive Self-Improvement

Why agent organizations need an autonomic nervous system, and how 4-layer vital monitoring, behavioral health diagnosis, self-repair orchestration, and failure-to-improvement conversion keep AI agents alive, healthy, and evolving

Creating AI agents is easy. Keeping them alive is hard. When agents scale beyond a handful, the problem shifts from intelligence to operations: heartbeats stop silently, processing queues back up, memory references decay, judgment quality degrades, and failures cascade across dependencies. MARIA VITAL addresses this by implementing a biological metaphor — the autonomic nervous system — for agent organizations. This paper presents the theoretical foundations in biological self-monitoring, the 4-layer architecture (Vital Signal, Behavioral Health, Recovery Orchestration, Recursive Improvement), the Health Score formalization, the self-repair pipeline with shadow agent validation, and the connection to biological homeostasis through the Observe-Diagnose-Recover-Improve loop.

MARIA VITAL:Agent組織のための生命維持システム — Heartbeat監視から再帰的自己改善まで

なぜAgent組織には自律神経系が必要なのか、そして4層バイタル監視、行動健全性診断、自己修復オーケストレーション、障害→改善変換がAIエージェントの生存・健康・進化を維持する方法

AIエージェントを作るのは簡単だ。生かし続けるのが難しい。エージェントが少数を超えてスケールすると、問題は知能から運用に移る:Heartbeatが静かに停止し、処理キューが詰まり、記憶参照が劣化し、判断品質が低下し、障害が依存関係を通じて連鎖する。MARIA VITALは生物学的メタファー — 自律神経系 — をAgent組織に実装することでこれに対処する。本論文では生物学的自己監視の理論的基盤、4層アーキテクチャ、Health Scoreの定式化、シャドーエージェント検証による自己修復パイプライン、そしてObserve-Diagnose-Recover-Improveループを通じた生物学的恒常性との接続を報告する。

Life as Continuous Self-Monitoring Systems

Why the essence of life is not replication but the Observe-Repair-Adapt loop

Life's defining feature is not DNA replication but the continuous self-monitoring and self-repair loops that maintain organismal integrity. This article traces the feedback architecture from molecular repair to nervous-system-level behavioral monitoring and connects it to MARIA VITAL's Heartbeat/Self-Repair/Evolution framework.

The Brain as a Recursive Self-Improving System

Predictive coding, dopamine learning, and the millisecond A/B test running inside your skull

The human brain continuously generates predictions, measures errors, and updates its own parameters — a recursive self-improvement loop that operates across timescales from milliseconds to decades. This article explores the neuroscience of predictive coding, dopamine reward prediction error, and synaptic plasticity as a blueprint for agent evolution.

The Immune System as Anti-Regression Architecture

Self/non-self discrimination as system drift detection — lessons from immunology for agent safety

The immune system is not merely a pathogen defense network. It is a sophisticated regression detection system that continuously monitors the body for deviations from known-safe states. This article examines immune architecture as a blueprint for agent anti-regression governance.

Homeostasis: The Operating System of Life

From Claude Bernard's milieu intérieur to allostasis — how closed-loop control sustains every living thing

Homeostasis — the maintenance of stable internal conditions despite external perturbation — is life's foundational operating system. This article traces the concept from its nineteenth-century origins through modern control theory and allostasis, connecting it to MARIA VITAL's 4-layer implementation architecture.

Evolution as Safe Mutation Governance

DNA repair, mutation rate control, and developmental constraints reveal evolution as a governed improvement process

Evolution is commonly misunderstood as purely random mutation plus natural selection. In reality, DNA repair mechanisms, mutation rate regulation, developmental constraints, and epigenetic inheritance make it a sophisticated governed mutation system. This article reframes evolution as a design pattern for safe agent self-improvement.
