創発的役割特化を統治する安定法則: 制約密度下のエージェント企業ダイナミクス

1. Introduction

1.1 The Agentic Company

An agentic company is an organization in which a significant fraction of operational decisions are made by autonomous AI agents rather than human employees. Unlike traditional automation — which replaces specific, well-defined tasks with deterministic programs — agentic operation replaces open-ended judgment with learned policies. An agent in an agentic company does not follow a script; it observes its environment, updates its beliefs, selects actions based on expected utility, and adapts its strategy in response to outcomes. The critical distinction is that agents interact with each other. A procurement agent's decision to switch suppliers affects the logistics agent's routing optimization, which affects the finance agent's cash flow projection, which feeds back into the procurement agent's supplier evaluation. These interaction effects are not incidental — they are the defining characteristic of agentic companies and the source of both their power and their instability.

Traditional organizational theory addresses coordination through hierarchy, standardization, and formal communication channels. These mechanisms were designed for human cognitive constraints: bounded rationality (Simon, 1955), limited span of control (Urwick, 1956), and communication overhead that grows super-linearly with team size (Brooks, 1975). Agents face none of these constraints. An agent can maintain awareness of every other agent's state. It can process thousands of coordination signals per second. It can instantaneously adopt any role for which it has a trained policy. This flexibility is precisely what makes agentic companies unstable: without the natural friction of human cognition, organizational structure can change faster than it can be governed.

1.2 The Role Specialization Problem

In any multi-agent system, agents must decide what to do. When multiple task types exist — planning, execution, auditing, negotiation, research, communication — agents must allocate themselves across these roles. Centralized assignment (a scheduler assigns roles) is simple but brittle: it creates a single point of failure, cannot adapt to local conditions, and requires global knowledge that is expensive to maintain. Decentralized assignment (each agent chooses its own role based on local information) is robust and adaptive but introduces a coordination problem: how do agents converge on an efficient division of labor without oscillating, clustering, or fragmenting?

This is the role specialization problem, and it is the central challenge of agentic company design. We want agents to spontaneously differentiate into roles that collectively cover all necessary functions, allocate capacity proportionally to demand, and maintain this allocation in the presence of perturbations. We want this specialization to emerge from local agent interactions rather than global planning. And we want formal guarantees that the emergence process converges rather than oscillating or diverging.

1.3 Governance as a Control Input

The key insight of this paper is that governance is not merely an overhead imposed on the system from outside — it is a control input that shapes the dynamics of role specialization. Governance constraints reduce the action space available to each agent. An agent that is constrained by an approval requirement before changing roles will change roles less frequently. An agent that must provide evidence for its role choice will specialize in roles for which evidence is easy to generate. An agent operating under a budget constraint will gravitate toward cost-effective roles.

These effects are not side effects of governance — they are the mechanism by which governance produces order. The question is how much governance is needed. Too little governance (low constraint density D) leaves the influence propagation matrix unchecked, allowing cascading role changes that destabilize the organization. Too much governance (high D) suppresses the very flexibility that makes agentic companies valuable, freezing agents into suboptimal roles. In this paper we distinguish two thresholds: the exact contraction condition (1 − D)λ_max(A) < 1, which determines whether the linearized dynamic converges at all, and the buffered specialization envelope λ_max(A) < 1 − D, which is stricter but preserves operational headroom against model error, asynchronous updates, and transient coupling spikes.

1.4 Contributions

This paper makes five contributions: 1. Model Definition. We formalize the agentic company as a time-varying graph G_t = (V, E_t, S_t, Π_t, R_t, D_t) with a five-dimensional state vector and governance constraint density (Section 2). 2. Influence Propagation Analysis. We define the influence propagation matrix A_t and characterize the spectral properties that determine system stability (Section 3). 3. Two-Level Stability Criterion. We separate the exact contraction condition (1 − D_t)λ_max(A_t) < 1 from the buffered specialization envelope λ_max(A_t) < 1 − D_t, and derive a four-regime phase diagram spanning Stagnation, Buffered Specialization, Fragile Specialization, and Cascade (Sections 5–6). 4. Multi-Layer Extension. We extend the framework to agentic companies operating within civilization-level governance layers, deriving effective constraint density and distinguishing pure contraction from buffered operation (Section 8). 5. Empirical Validation. We validate the buffered operating boundary on the MARIA OS Planet-100 simulation with 111 agents and 10 role types, achieving 96.8% classification accuracy (Section 10).

2. Model Definition

2.1 The Agentic Company Graph

Definition 1 (Agentic Company). An agentic company at time t is a tuple: G_t = (V, E_t, S_t, Π_t, R_t, D_t) where: - V = {v_1, v_2, ..., v_N} is the set of N agents (fixed population). - E_t ⊆ V × V is the set of directed influence edges at time t. An edge (v_i, v_j) ∈ E_t indicates that agent v_i has a non-zero influence on agent v_j's role choice at time t. - S_t: V → ℝ^5 assigns each agent a five-dimensional state vector. - Π_t: V → Δ(Actions) assigns each agent a probability distribution over available actions (its policy). - R_t: V × Actions → ℝ is the reward function mapping agent-action pairs to scalar rewards. - D_t ∈ [0, 1] is the governance constraint density.

2.2 The State Vector

各エージェント v_i には、次の 5 つのコンポーネントを持つ状態ベクトル S_t(v_i) = [F_t, K_t, H_t, L_t, C_t] があります。 |コンポーネント |記号 |説明 |範囲 | |----------|----------|---------------|----------| |財務資本 | F_t |予算、収益能力、リソース配分 | [0, ∞) | |ナレッジキャピタル | K_t |蓄積された専門知識、訓練されたスキル、モデルの品質 | [0, 1] | |ヘルスキャピタル | H_t |動作の信頼性、稼働時間、エラー率の逆 | [0, 1] | |正当性資本 | L_t |ガバナンスからの信頼スコア、監査合格率 | [0, 1] | |調整資本 | C_t |ネットワーク位置の値、影響中心性 | [0, 1] | 状態ベクトルは次のように進化します。 S_{t+1}(v_i) = f(S_t(v_i), π_t(v_i), R_t(v_i), D_t, {S_t(v_j) : (v_j, v_i) ∈ E_t}) ここで、「f」は状態遷移関数です。近隣の状態への依存 {S_t(v_j)} は、influence propagates. The dependence on D_t is the mechanism through which governance shapes dynamics.

2.3 ガバナンスの制約密度

Definition 2 (Governance Constraint Density). The governance constraint density at time t is: D_t = |Constraints_t| / |ActionSpace_t| where |Constraints_t| is the number of active constraints (approval gates, evidence requirements, budget limits, role-change cooldowns, audit triggers) and |ActionSpace_t| is the total number of available actions across all agents. Intuitively, D_t measures the fraction of the action space that is restricted by governance. When D_t = 0, agents face no constraints and can take any action at any time. When D_t = 1, every action requires approval and the system is fully locked. In practice, operational agentic companies operate in the range D_t ∈ [0.15, 0.70]. The constraint density is not merely a count of rules. It accounts for the interaction between constraints and the action space. Adding a constraint that restricts an action no agent would take does not increase D_t. Removing an action that was already constrained does not decrease D_t. The density is a genuine ratio that reflects the effective governance burden on agent behavior.

2.4 Role Space and Assignment

定義 3 (役割空間)。 役割空間 ℛ = {r_1, r_2, ..., r_M} は、M 個の機能的役割の有限集合です。各役割「r_k」は、タスクの配分、スキル要件ベクトル、報酬プロファイルによって特徴付けられます。 時刻「t」における役割の割り当ては、各エージェントを役割にマッピングする関数「ρ_t: V → ℛ」です。集合的な役割分布はベクトル ρ̂_t ∈ Δ^M であり、 ρ̂_t(k) = |{v_i : ρ_t(v_i) = r_k}| となります。 / N は、ロール r_k に割り当てられたエージェントの割合です。 モデリング上の重要な選択は、ガバナンスの制約に従って、エージェントがタイム ステップごとに役割を変更できることです。たとえば、役割変更のクールダウン制約により、エージェントは「τ」ステップごとに複数回役割を切り替えることができなくなります。これは、最近役割を切り替えたエージェントの有効なアクション スペースを直接削減し、それによって局所的に「D_t」を増加させるガバナンス メカニズムです。

2.5 The Markov Decision Process Formulation

From each agent's perspective, the agentic company is a partially observable Markov decision process (POMDP). Agent v_i at time t observes a local state o_t(v_i) comprising its own state S_t(v_i), the states of its neighbors {S_t(v_j) : (v_j, v_i) ∈ E_t}, and the current governance parameters D_t. Based on this observation, it selects a role r_i(t+1) and an action within that role. The reward R_t(v_i, a) depends on the agent's action, the actions of other agents (through task completion and coordination effects), and the governance context. The key challenge is that the MDP is non-stationary: the transition dynamics change as other agents change their roles. Agent v_i's optimal policy depends on the policies of all other agents, which depend on v_i's policy — a classic Nash equilibrium problem. Our stability analysis addresses whether the system of coupled MDPs converges to a fixed point (stable specialization) or cycles indefinitely (chaos).

3. Influence Propagation

3.1 The Influence Matrix

Definition 4 (Influence Matrix). The influence propagation matrix A_t ∈ ℝ^{N×N} is defined as: A_t[i, j] = ∂U_j(r_j | ρ_t) / ∂ρ_t(v_i) where U_j(r_j | ρ_t) is agent v_j's utility for its current role r_j given the current role assignment ρ_t, and the partial derivative measures how a marginal change in agent v_i's role choice affects agent v_j's utility. Intuitively, A_t[i, j] measures how much agent v_i's role change would perturb agent v_j's incentives. Large positive values indicate strong complementarity (if v_i changes to a role that makes v_j's current role more valuable). Large negative values indicate substitution effects (if v_i changes to the same role as v_j, reducing v_j's utility through competition). The diagonal is zero by convention: A_t[i, i] = 0.

The influence matrix captures three types of inter-agent effects: 1. Task complementarity. If agent v_i specializes in planning and agent v_j specializes in execution, v_i's planning output feeds v_j's execution pipeline. Changes in v_i's role disrupt this pipeline, creating a positive off-diagonal entry. 2. Resource competition. If v_i and v_j both specialize in the same role, they compete for the same task pool. Each additional agent in a role reduces the marginal return, creating negative entries. 3. Information effects. Agent v_i's role choice signals information about the state of the environment (e.g., if v_i switches to an auditing role, it may signal that error rates are high). This information affects v_j's utility estimates even if there is no direct task or resource interaction.

3.2 Spectral Radius and Propagation Dynamics

Definition 5 (Spectral Radius). The spectral radius of A_t is: λ_max(A_t) = max{|λ| : λ ∈ spectrum(A_t)} where spectrum(A_t) is the set of eigenvalues of A_t. The spectral radius controls how influence perturbations propagate through the network. Consider a perturbation δρ_0 to the role assignment at time t = 0. After one round of best-response updates, the perturbation to agent utilities is approximately A_t · δρ_0. After k rounds, the cumulative perturbation is: δU_k ≈ A_t^k · δρ_0 The norm of this perturbation grows as ||δU_k|| ≤ ||A_t||^k · ||δρ_0||. For large k, this is dominated by the spectral radius: ||δU_k|| ∼ λ_max(A_t)^k · ||δρ_0|| If λ_max(A_t) < 1, perturbations decay exponentially: each round of best-response updates shrinks the displacement, and the system converges to a fixed point. If λ_max(A_t) > 1, perturbations grow exponentially: each round amplifies the displacement, and the system diverges. If λ_max(A_t) = 1, the system is marginally stable and requires higher-order analysis.

3.3 ガバナンスの減衰

ガバナンスの制約は、影響力の伝播に対する減衰メカニズムとして機能します。エージェントが役割を変更する前に承認要件に直面すると、エージェントはインセンティブの変更にすぐに対応できないため、そのエージェントに対する実効的な影響は減少します。承認を待つ必要があり、その間にインセンティブが再び変更される可能性があります。エージェントがその役割選択の証拠を提供する必要がある場合、証拠の収集により平滑化の遅れが生じるため、エージェントはユーティリティ環境の一時的な変動に対する反応が鈍くなります。 形式的には、制約密度 D_t を使用したガバナンスは、有効影響行列を次のように削減します。 A_t^{eff} = (1 − D_t) · A_t 係数 (1 − D_t) は、すべての影響の強さを均一にスケールします。これは一次近似です。実際には、異なる制約は異なるエージェントおよび異なる影響チャネルに非対称的に影響します。均一なスケーリングcaptures the aggregate effect: a fraction D_t of the action space is constrained, so a fraction D_t of influence-induced role changes are blocked. The effective spectral radius is: λ_max(A_t^{eff}) = (1 − D_t) · λ_max(A_t) The exact first-order contraction condition is therefore: (1 − D_t) · λ_max(A_t) < 1 which is equivalent to: λ_max(A_t) < 1 / (1 − D_t) This is the mathematically correct local stability condition for the linearized system. But enterprise architects usually need something stricter than bare contraction. A system with loop gain 0.99 is technically stable and still operationally brittle: convergence is slow, estimation error can flip the sign, and bursty or asynchronous updates can push the organization into oscillation. For that reason we define the Buffered Specialization Law: λ_max(A_t) < 1 − D_t Because 1 − D_t < 1 / (1 − D_t) for D_t ∈ (0, 1), this law is conservative. It guarantees contraction and preserves adaptation headroom, creating a region where specialization is not merely stable in theory but robust in operation.

4. Role Specialization Dynamics

4.1 The Role Selection Rule

Each agent selects its role at each time step according to a utility-maximizing rule: Definition 6 (Role Selection). Agent v_i at time t selects: r_i(t+1) = argmax_r U_i(r | C_task, B_comm, D_t) where U_i is the role utility function, C_task is the current task context (available tasks, deadlines, priorities), B_comm is the communication bandwidth available to v_i, and D_t is the governance constraint density. This selection rule is myopic: the agent maximizes immediate utility without planning ahead. This is a deliberate simplification. In practice, agents may use multi-step lookahead (reinforcement learning policies), but the stability analysis applies to the best-response dynamics of the myopic rule, which forms the foundation for more sophisticated policies. If the myopic dynamics are unstable, no amount of lookahead can stabilize them without changing the influence structure itself.

4.2 ユーティリティ関数

The role utility function decomposes into three components: U_i(r) = α · Eff_i(r) + β · Impact_i(r) − γ · Cost_i(r, D_t) where α, β, γ > 0 are weighting parameters with α + β + γ = 1. Efficiency `Eff_i(r)`. This measures how well agent v_i's capabilities match role r's requirements. It is a function of the agent's knowledge capital K_t(v_i) and the skill profile of role r: Eff_i(r) = 1 − ||K_t(v_i) − K_req(r)||_2 / ||K_req(r)||_2 where K_req(r) is the required skill vector for role r. An agent whose knowledge profile exactly matches the role requirements achieves Eff = 1. An agent with no relevant skills achieves Eff ≤ 0. Impact `Impact_i(r)`. This measures the marginal contribution of agent v_i in role r to the overall organizational output. It depends on the current role distribution: if many agents are already in role r, the marginal impact of one more is low (diminishing returns). If no agents are in role r and there is demand for it, the marginal impact is high: Impact_i(r) = Demand(r) / (1 + n_r) where Demand(r) is the current task demand for role r and n_r is the number of agents currently in role r. This creates a natural load-balancing effect: excess agents in one role are drawn toward under-served roles. Cost `Cost_i(r, D_t)`. This measures the governance burden of agent v_i operating in role r under constraint density D_t. Higher constraint density increases the cost of every role because more actions require approval, evidence, or waiting: Cost_i(r, D_t) = D_t · (1 + SwitchCost(r, ρ_t(v_i))) where SwitchCost(r, ρ_t(v_i)) is the cost of switching from the current role ρ_t(v_i) to role r. This is zero if the agent is already in role r and positive otherwise, reflecting the governance overhead of role transitions (approval delays, re-certification, evidence requirements). The cost term creates a stickiness effect: under high D_t, agents are reluctant to change roles because the governance cost of switching is high. This is the direct mechanism through which governance damping operates at the agent level.

4.3 Best-Response Dynamics

役割選択ルールを同時に適用する「N」個のエージェントのシステムにより、最良の応答ダイナミクスが定義されます。各タイム ステップで、すべてのエージェントはすべての役割に対するユーティリティを計算し、(ガバナンスの制約に従って) 最適なものに切り替えます。問題は、この力学が収束するかどうかです。 ρ_t ∈ ℛ^N を時間 t における役割割り当てベクトルとする。最良の応答マップは次のとおりです。 BR(ρ_t) = (argmax_r U_1(r | ρ_t, D_t), ..., argmax_r U_N(r | ρ_t, D_t)) 安定した役割割り当ては、「BR」の固定点、つまり「BR(ρ) = ρ」となるような役割ベクトル「ρ*」です。固定点では、他のすべてのエージェントの役割を考慮すると、どのエージェントもその役割を変更するインセンティブを持ちません。これはまさに役割選択ゲームのナッシュ均衡です。 固定点の存在は、混合戦略 (役割にわたる確率分布) に拡張すると、Brouwer の定理によって保証されます。問題は最善の対応かどうかだdynamic converges to this fixed point from arbitrary initial conditions. This is where the spectral radius condition enters.

4.4 平衡に近い線形化されたダイナミクス

固定点 ρ* の近くでは、最良応答ダイナミクスを線形化できます。 δρ_t = ρ_t − ρ* を平衡からの偏差とする。線形化された更新は次のとおりです。 δρ_{t+1} = J(BR) · δρ_t ここで、J(BR) は、ρ* における最良応答マップのヤコビアンです。ヤコビアンは、役割の割り当てにおける小さな変更が、すべてのエージェントの最良の応答の更新を通じてどのように伝播するかを捉えます。行列 J(BR) は、効用関数を通じて影響行列 A_t に直接関連付けられます。 J(BR)[i, j] = ∂(argmax_r U_i(r | ρ))[j] / ∂ρ_j 滑らかな効用近似 (不連続性を避けるために argmax がソフトマックスに置き換えられる) では、ヤコビアンは有効影響行列に比例します。 J(BR) ≈ (1 − D_t) · A_t 線形化された動的関数は、「J(BR)」のすべての固有値の法が 1 未満である場合にのみ収束します。それには、「(1 − D_t) · λ_max(A_t) < 1」が必要です。バッファされた特殊化condition λ_max(A_t) < 1 − D_t identifies the subset of that stable region with explicit governance reserve against perturbations in D_t, estimation error in A_t, and asynchronous update jitter.

5. The Stability Law

5.1 Main Theorem

Theorem 1 (Exact Local Stability Law). Let G_t = (V, E_t, S_t, Π_t, R_t, D_t) be an agentic company with N agents, M roles, influence matrix A_t, and governance constraint density D_t ∈ (0, 1). Under Assumptions A1–A4 (stated below), the linearized best-response dynamic converges locally to a stable role assignment ρ* if and only if: (1 − D_t) · λ_max(A_t) < 1 Moreover, when the condition holds, convergence is exponential with rate r = 1 − (1 − D_t) · λ_max(A_t), and the number of steps to reach an ε-neighborhood of ρ* is at most: T(ε) = ⌈log(||δρ_0|| / ε) / (-log((1 − D_t) · λ_max(A_t)))⌉

前提: - A1 (Smooth Utilities)。 効用関数 U_i(r | ρ, D) は、すべての i、r、および D に対する役割分布 ρ で 2 回連続微分可能です。 - A2 (境界影響)。 影響行列は、t とは独立したいくつかの有限境界 B に対して ||A_t||_F ≤ B を満たします。ここで、||.||_F はフロベニウス ノルムです。 - A3 (非縮退ガバナンス)。 制約密度は、すべての t について 0 < D_t < 1 を満たします。完全に管理されていないシステムや完全に凍結されたシステムはありません。 - A4 (同期更新)。 すべてのエージェントは、各タイム ステップで自分の役割の選択を同時に更新します。非同期のバリアントについてはセクション 7 で説明します。

5.2 Proof Sketch

Necessity (`(1 − D)λ_max ≥ 1` implies non-contraction). Suppose (1 − D_t) · λ_max(A_t) ≥ 1. Then there exists an eigenvector ξ of A_t with eigenvalue λ such that |(1 − D_t) · λ| ≥ 1. Consider a perturbation δρ_0 = εξ for small ε > 0. The linearized update gives: δρ_1 = (1 − D_t) · A_t · εξ = (1 − D_t) · λ · εξ The perturbation does not shrink in this eigen-direction, so the linearized map cannot be contractive. If the modulus is strictly larger than 1, perturbations grow exponentially and the equilibrium is locally unstable. Sufficiency (`(1 − D)λ_max < 1` implies convergence). Suppose (1 − D_t) · λ_max(A_t) < 1. Then the effective spectral radius of the Jacobian satisfies: ρ(J(BR)) = (1 − D_t) · λ_max(A_t) < 1 By the contraction mapping theorem, the best-response map BR is a contraction on a neighborhood of ρ* with rate (1 − D_t) · λ_max(A_t). The Banach fixed-point theorem guarantees local existence, uniqueness, and exponential convergence of the iterates ρ_t = BR^t(ρ_0) to ρ*. The stronger buffered specialization condition λ_max(A_t) < 1 − D_t is not the exact necessity threshold; it is a conservative design corollary. It carves out the portion of the stable region where governance retains explicit reserve against finite-sample uncertainty and operational perturbations.

5.3 Intuition

Two scalar quantities matter in practice: - Loop gain g = (1 − D) · λ_max(A). This is the exact contraction diagnostic. If g < 1, perturbations decay. If g ≥ 1, perturbations persist or grow. - Buffer margin δ_buffer = 1 − D − λ_max(A). This is the conservative operating reserve. If δ_buffer > 0, the organization is not just contractive but comfortably inside the buffered specialization envelope. These quantities resolve a common confusion. More governance always reduces the loop gain because it damps influence. But more governance also reduces freedom, and therefore shrinks the buffer available for productive adaptation. A company can be mathematically stable (g < 1) and still operationally brittle (δ_buffer ≈ 0). The buffered law is therefore a governance design rule, not merely a mathematical curiosity.

6. 状態図

6.1 4つの体制

厳密法則とバッファ法則を組み合わせたものにより、「(λ_max, D)」パラメータ空間が実質的に異なる 4 つの領域に分割されます。 フェーズ I: 停滞 (D > D_stag、通常は D_stag ≈ 0.7) このフェーズでは、ガバナンスの制約密度が非常に高いため、エージェントはその役割を効果的に適応できません。コスト項 γ · Cost(r, D_t) が支配的であり、ロールの切り替えに法外なコストがかかります。このシステムは、縮小という意味では非常に安定しているかもしれませんが、組織的には健全ではありません。 停滞フェーズで観察可能な指標: - 役割変更頻度 ≈ 0 - 需要の変化によりタスク完了率が低下 - ガバナンス間接費比率 > 60% - イノベーション率 ≈ 0 フェーズ II: バッファリングされた特殊化 (λ_max < 1 − D、D < D_stag を使用) これは望ましい動作体制です。エージェントには適応する十分な自由があり、ループ ゲインは快適に 1 未満であり、組織は明示的な情報を保持します。governance reserve. Perturbations are damped quickly, and specialization patterns remain legible under moderate shocks. Observable metrics in the Buffered Specialization phase: - Role distribution converges within 80–200 steps - Task completion rate > 90% - Role entropy stabilizes at an intermediate value - Perturbation recovery time remains bounded and predictable Phase III: Fragile Specialization (1 − D ≤ λ_max < 1 / (1 − D), with D < D_stag) Here the organization is still locally contractive, but only barely. It converges under the nominal model, yet small topology changes, delayed approvals, or asynchronous bursts can trigger long oscillation tails. This is the regime that often looks healthy in a dashboard until a mild stress event exposes the missing buffer. Observable metrics in the Fragile Specialization phase: - Convergence occurs but only after long settling times - Recovery time is highly variable across trials - Role entropy overshoots before settling - Alert frequency rises even though the system eventually reconverges Phase IV: Cascade ((1 − D)λ_max ≥ 1) In this phase, influence propagation dominates governance damping. When one agent changes roles, the utility perturbation propagates through the network, causing multiple other agents to change roles, which generates further perturbations, creating a cascade that does not contract. Observable metrics in the Cascade phase: - Role assignment entropy approaches its maximum - Task completion rate < 40% - Influence cascade length is effectively unbounded - Coordination capital C_t collapses toward zero

6.2 位相境界

2 つの境界が重要です。 - バッファリングされた動作境界は、直線 λ_max = 1 − D です。この線より下の点は、バッファーされた特殊化にあります。 - 正確な縮小境界は双曲線 λ_max = 1 / (1 − D) です。この境界を越えると、システムは Fragile Specialization から Cascade に移行します。 バッファーされた専門化と停滞の間の境界はそれほど明確ではありません。停滞しきい値を制約密度 D_stag として定義します。このしきい値を超えると、期待される役割変更率が 1,000 エージェント ステップあたり 1 回の変更を下回ります。経験的に、実験で使用したユーティリティ関数パラメータの「D_stag ≈ 0.70」ですが、このしきい値は「α、β、γ」の特定の値とスイッチコスト関数に依存します。 |フェーズ |地域 |行動 |収束 | |----------|----------|----------|---------------| |停滞 | D > D_stag |凍結された役割 |些細なこと | |緩衝専門分野 | λ_max < 1 − D、D < D_stag |堅牢な収束特化 |健全な予備力を持つ指数関数的 | |脆弱な専門分野 | 1 − D ≤ λ_max < 1 / (1 − D)、D < D_stag |収束するが脆い |遅い / 差異に敏感 | |カスケード | (1 − D)λ_max ≥ 1 |振動性または発散性 |なし | 相図は基本的なトレードオフを明らかにします。ガバナンスを強化するとループゲインが低下するため、縮小が促進されますが、運用バッファーも縮小し、最終的には組織が停滞に陥る可能性があります。実際の最適値は、範囲 '[0.30, 0.55]' の 'D' を持つバッファリングされた領域にあります。これは、カスケードを防ぐのに十分な構造、適応特殊化を維持するのに十分な自由度です。

6.3 重大な行為

Two kinds of critical slowing matter: - Near the exact contraction boundary, the loop gain approaches unity and convergence time scales as: T(ε) ∼ 1 / (1 - (1 − D)λ_max) as ((1 − D)λ_max) → 1^- - Near the buffered boundary, the buffer margin vanishes and operational variance rises as: Var(Δρ) ∼ 1 / (1 − D − λ_max)^2 The first quantity captures mathematical loss of contraction; the second captures practical loss of governance reserve. In networks with structured topology (e.g., the MARIA coordinate hierarchy), the exponents may differ, but the distinction between exact stability and buffered operation remains essential.

7. 収束解析

7.1 Main Convergence Result

Theorem 2 (Exponential Convergence). Under the exact stability condition (1 − D_t) · λ_max(A_t) < 1, the expected state deviation converges exponentially: lim_{t → ∞} E[||S_{t+1} − S_t||] = 0 Moreover, the convergence rate is: E[||S_{t+1} − S_t||] ≤ c_0 · ((1 − D) · λ_max)^t where c_0 = ||S_1 − S_0|| is the initial state change magnitude. Proof. The state vector S_t(v_i) evolves according to the transition function f defined in Section 2.2. Near the fixed point S*, the linearized dynamics are governed by the Jacobian: δS_{t+1} = J_f · δS_t where J_f is the Jacobian of the state transition function with respect to the state vector. The key observation is that J_f decomposes as: J_f = J_self + (1 − D_t) · J_influence where J_self captures each agent's intrinsic state dynamics (bounded below 1 for any stable agent) and J_influence captures the inter-agent influence terms mediated by A_t. When the combined loop gain remains below 1, the linearized operator is a contraction and the deviation norm decays geometrically. Exponential convergence follows from the submultiplicativity of the operator norm under iteration.

7.2 Necessary Conditions for Convergence

The convergence result requires four necessary conditions: 1. Individual Agent Stability. Each agent, considered in isolation (with fixed neighbor states), must converge to a stable state. This excludes agents with internally chaotic dynamics (e.g., oscillating reward estimates due to non-stationary exploration policies). Formally: ρ(J_self(v_i)) < 1 for all v_i. 2. Bounded Influence. The influence matrix must have bounded spectral radius. This is guaranteed by Assumption A2 (bounded Frobenius norm) and is satisfied in practice for any finite network with finite utility gradients. 3. Non-Zero Governance. The constraint density must be strictly positive: D_t > 0. A completely ungoverned system (D = 0) has stability condition λ_max < 1, which is generically violated in densely connected networks. Some governance is always necessary for stability in multi-agent systems. 4. Consistent Constraints. Governance constraints must be consistent: they must not create cycles where an agent is forced to change roles to satisfy one constraint and then forced to change back to satisfy another. Consistent constraints can be verified by checking that the constraint graph is acyclic.

7.3 Asynchronous Updates

Theorem 1 assumes synchronous updates (Assumption A4). In practice, agents may update asynchronously — each agent updates at its own rate, possibly triggered by events rather than a global clock. Proposition 1 (Asynchronous Stability). If the exact stability condition (1 − D_t) · λ_max(A_t) < 1 holds, then the best-response dynamic converges under any asynchronous update schedule in which every agent updates infinitely often. Proof sketch. Under asynchronous updates, the effective update operator at each step affects only a subset of agents. The spectral radius of any principal submatrix of A_t is at most λ_max(A_t) (eigenvalue interlacing). Therefore, each partial update remains contractive when the global loop gain is below 1, and the composition of contractions is itself a contraction. Convergence follows from the standard theory of asynchronous iterations on paracontracting operators. The practical implication is that the exact gain condition governs mathematical convergence regardless of update ordering, while the buffered envelope remains the recommended target for robust production operation.

7.4 Convergence Speed

The convergence speed is controlled by the effective loop gain λ_{eff} = (1 − D) · λ_max. Faster convergence requires either: 1. Lower `λ_max` — weaker inter-agent influence (sparser network, weaker complementarities) 2. Higher `D` — stronger governance damping (more constraints, slower role changes) Option 1 is a design choice (network topology, utility design). Option 2 is a governance choice. The trade-off is that faster contraction via higher D comes at the cost of reduced adaptivity and, beyond a point, stagnation. In the Planet-100 experiments (Section 10), convergence to within ε = 0.01 of the buffered specialization distribution required 80–200 steps in the buffered regime. Systems in the fragile regime also converged, but with much higher variance and much longer settling times.

8. Civilization Extension: Multi-Layer Stability

8.1 Governance Layers

Agentic Companyは単独で活動するわけではありません。それは、規制の枠組み、業界標準、市場状況の中に存在し、また、MARIA OS のコンテキストでは、独自のガバナンス制約を課す文明シミュレーションの中に潜在的に存在します。これらの外部層により、安定性解析で考慮する必要がある追加の拘束密度が追加されます。 2 層システムを考えてみましょう。内部ガバナンス密度「D_company」を持つAgentic Companyが、外部ガバナンス密度「D_civ」を持つ文明 (または規制環境) 内で運営されています。企業レベルの制約により、個々のエージェントのアクション (承認ゲート、証拠要件、役割変更のクールダウン) が制限されます。文明レベルの制約は、企業全体の行動 (規制遵守、市場ルール、条約の義務) を制限します。

8.2 実効制約密度

Definition 7 (Effective Constraint Density). For a two-layer governance system with company-level density D_company and civilization-level density D_civ, the effective constraint density is: D_eff = 1 − (1 − D_company)(1 − D_civ) Expanding: D_eff = D_company + D_civ − D_company · D_civ This formula has an intuitive interpretation. The freedom of an agent is the fraction of its action space that is unconstrained. Company-level governance leaves a fraction (1 − D_company) unconstrained. Civilization-level governance further constrains a fraction D_civ of the remaining freedom. The residual freedom is (1 − D_company)(1 − D_civ), so the effective density is 1 − (1 − D_company)(1 − D_civ). Note that D_eff > max(D_company, D_civ) whenever both are non-zero: multiple governance layers always increase effective constraint density. This has important implications for multi-layer stability.

8.3 Multi-Layer Stability Law

Theorem 3 (Multi-Layer Exact Stability). For a two-layer governance system, the exact contraction condition becomes: (1 − D_company)(1 − D_civ) · λ_max(A_t) < 1 Equivalently: λ_max(A_t) < 1 / (1 − D_eff) Adding a civilization layer with D_civ = 0.2 to a company with D_company = 0.3 gives D_eff = 0.44, so the exact contraction condition becomes λ_max < 1 / 0.56 ≈ 1.79. Corollary 1 (Buffered Multi-Layer Operation). The conservative buffered envelope becomes: λ_max(A_t) < 1 − D_eff = (1 − D_company)(1 − D_civ) This is the recommended production condition for robust specialization across layers. Corollary 2. Additional governance layers reduce the buffered operating region even while they improve pure damping. In other words, layered regulation can make contraction easier but still push the organization toward stagnation by exhausting adaptation headroom. Corollary 3. There exists a maximum number of governance layers L_max beyond which buffered specialization is no longer possible for a given λ_max: L_max = ⌈log(λ_max) / log(1 − D_avg)⌉ where D_avg is the average constraint density across layers. For typical values (λ_max = 0.7, D_avg = 0.2), this gives L_max ≈ 3 layers before the system exits the buffered region even though exact contraction may still hold.

8.4 文明シミュレーションマッピング

In the MARIA OS Civilization simulation (Section 10), nations correspond to agentic companies, and the civilization-level governance includes: - Market rules (free market land economy, trading constraints) - Election cycles (political transitions that reset governance parameters) - Treaty obligations (inter-nation constraints on resource allocation) - LOGOS AI advisor recommendations (soft constraints that influence but do not mandate policy) Each of these contributes to D_civ. The effective constraint density for a nation is: D_eff(nation) = 1 − (1 − D_internal)(1 − D_market)(1 − D_political)(1 − D_treaty)(1 − D_LOGOS) where each sub-density captures a different governance channel. This decomposition allows the Civilization simulation to model how different governance structures (authoritarian vs. democratic, regulated vs. free-market) produce different 実効拘束密度、したがって異なる安定性特性。

9.2 Gate Engine as Governance Density Controller

The MARIA OS Gate Engine (implemented in lib/engine/decision-pipeline.ts and lib/engine/responsibility-gates.ts) is the primary mechanism for controlling governance constraint density. Each gate type contributes to D_t: - Approval Gates increase D by restricting actions that require human sign-off. The number of active approval gates divided by total action count directly contributes to D_t. - Evidence Gates increase D by requiring agents to collect and present evidence before acting. Each evidence requirement adds a constraint to the action space. - Budget Gates increase D by capping the financial resources available for role changes and task execution. - Cooldown Gates increase D by imposing temporal constraints on how frequently agents can change roles. The gate engine provides real-time monitoring of D_t across all organizational levels, enabling administrators to tune governance intensity to maintain the stability condition. When λ_max is estimated to be rising (e.g., due to increased network connectivity or stronger complementarities), D_t can be increased by activating additional gates. When D_t is too high (risk of Stagnation), gates can be relaxed. This is the core operational insight: governance gates are not bureaucratic checkpoints — they are control inputs in a dynamical system. Tuning gate parameters is equivalent to choosing the damping coefficient in a control loop.

9.3 Evidence Layer as Influence Damper

The MARIA OS evidence layer (implemented in lib/engine/evidence.ts) serves a dual purpose in the stability framework. First, it provides the audit trail required for accountability. Second, it acts as an influence damper by introducing delay between an agent's decision to change roles and the execution of that change. When an agent decides to switch roles, the evidence requirement forces it to: 1. Collect evidence supporting the switch (task demand data, capability match scores, coordination impact estimates) 2. Bundle the evidence into an evidence package 3. Submit the package for review (automated or human) 4. Wait for approval before executing the switch This delay prevents agents from responding instantaneously to utility perturbations. The smoothing effect is analogous to a low-pass filter: high-frequency role oscillations are filtered out because the evidence collection process takes longer than the oscillation period. Only sustained, genuine shifts in utility survive the evidence filter and produce actual role changes.

9.4 Anomaly Detection: Stability Monitoring

MARIA OS implements real-time stability monitoring through the analytics engine (lib/engine/analytics.ts). The key metrics tracked are: 1. Spectral Radius Estimate. The influence matrix A_t is estimated from observed agent interactions (role changes, utility perturbations). The spectral radius is computed at regular intervals using power iteration on the empirical influence matrix. 2. Constraint Density Measurement. D_t is computed from the active gate configuration and the current action space size. 3. Loop Gain. The exact stability diagnostic g_t = (1 − D_t) · λ_max(A_t) is tracked in real time. When g_t approaches 1, the system is nearing loss of contraction. 4. Buffer Margin. The conservative operating reserve δ_buffer = 1 − D_t − λ_max(A_t) is tracked in parallel. When δ_buffer approaches zero, the organization is entering the fragile regime even if contraction still holds. 5. Role Change Frequency. A sudden increase in role change frequency is an early indicator of approaching the cascade boundary. 6. Perturbation Recovery Time. The time for the system to return to steady state after a perturbation is measured. Increasing recovery time indicates critical slowing down near the boundary. When either g_t > 0.95 or δ_buffer < 0.10, the anomaly detection system triggers an alert and can activate additional governance gates to increase D_t. This creates a self-stabilizing feedback loop: instability triggers governance, governance restores contraction and, where possible, rebuilds operating buffer.

9.5 Universe Dashboard Integration

The stability metrics are surfaced in the MARIA OS Universe Dashboard through the dashboard data provider (lib/contexts/dashboard-data-context.tsx). Each Universe view includes: - Loop-Gain Gauge: A real-time display of g_t = (1 − D_t)λ_max(A_t), color-coded green (safe), amber (warning), red (critical). - Buffer Gauge: A display of δ_buffer = 1 − D_t − λ_max(A_t), showing whether the organization is buffered or fragile. - Phase Indicator: Current operating phase (Stagnation / Buffered Specialization / Fragile Specialization / Cascade) based on the (λ_max, D) coordinates. - Convergence Timer: Estimated steps to steady-state role distribution, computed from T(ε) = log(||δρ_0|| / ε) / (-log(λ_{eff})). - Role Distribution Chart: Real-time histogram of agent-to-role assignments, showing convergence toward the equilibrium distribution. - Influence Heatmap: Visualization of the N × N influence matrix A_t, highlighting the dominant eigenvector (the direction of maximum instability).

10. プラネット-100の実験

10.1 実験のセットアップ

MARIA OS Planet-100 シミュレーション環境 (app/experimental/planet-100/) を使用して安定性則を検証します。 Planet-100 は、自律エージェントの自己組織化社会をシミュレートし、新たな役割の専門化を研究するための制御されたテストベッドを提供します。 構成: |パラメータ |値 | |----------|----------| |エージェント数 (N) | 111 | |役割の種類 (M) | 10名 (プランナー、執行者、監査人、交渉者、研究者、コミュニケーター、アナリスト、ガーディアン、オプティマイザー、コーディネーター) | |シミュレーションの手順 |トライアルごとに 1,000 | |構成ごとのトライアル | 50 | |ユーティリティウェイト | α = 0.4、β = 0.35、γ = 0.25 | |トポロジに影響を与える |スケールフリー（優先アタッチメント、m = 3） | | PRNG |再現性を高めるための決定的シード (mulberry32) | 111 人のエージェントは、Planet-100 の人口に対応します (100 人の主要エージェントと 11 人の統治オブザーバー)。 10 の役割タイプは機能を表します。roles identified in the MARIA OS agent taxonomy. The scale-free topology produces a power-law degree distribution, which is representative of real organizational networks where some agents (hubs) have disproportionate influence.

10.2 Parameter Sweeps

We conduct two parameter sweeps: Sweep 1: Constraint Density `D` ∈ [0.05, 0.90] at fixed topology. The influence matrix A_t is fixed (same topology for all trials), and D is varied in increments of 0.05. For each value of D, we run 50 trials with random initial role assignments and measure: - Whether the role distribution converges (defined as ||S_{t+1} − S_t|| < 0.01 for 20 consecutive steps) - The convergence time (number of steps to reach the convergence criterion) - The final role entropy H(ρ̂) = −Σ_k ρ̂(k) · log(ρ̂(k)) - The task completion rate at steady state Sweep 2: Spectral Radius `λ_max` ∈ [0.2, 1.5] at fixed `D`. The constraint density is fixed at D = 0.40, and the influence matrix is scaled to achieve different spectral radii. Specifically, we compute the natural influence matrix A_0 from the scale-free topology and scale it: A_t = s · A_0 where s = λ_target / λ_max(A_0). This preserves the structure of the influence network while controlling its strength. For each value of λ_max, we run 50 trials and measure the same convergence metrics.

10.3 Buffered Boundary Reproduction

The combined results from both sweeps produce an empirical phase diagram in the (λ_max, D) plane. For the purposes of deployment guidance, we classify each point as buffered or non-buffered using the conservative operating boundary λ_max = 1 − D, while separately tracking whether the exact contraction condition is still satisfied. The empirical buffered boundary closely matches the theoretical prediction. Specifically: | Metric | Value | |--------|-------| | Buffered boundary classification accuracy | 96.8% | | Mean absolute error of buffered boundary | 0.032 | | False buffered (predicted buffered, actually fragile/cascade) | 1.4% | | False non-buffered (predicted fragile, actually buffered) | 1.8% | The 3.2% misclassification rate occurs at points very close to the boundary (|λ_max − (1 − D)| < 0.05), where finite-time effects and the discreteness of the agent population cause deviations from the infinite-population, continuous-time theory. The false buffered rate (1.4%) represents configurations that appear robust in early steps but are actually fragile under longer horizons. The false non-buffered rate (1.8%) represents configurations where nonlinear saturation provides a little more damping than the linear buffered model predicts.

10.5 最適なガバナンス密度

We define the optimal governance density D* as the value that maximizes a combined objective: Objective(D) = TaskCompletion(D) · Adaptivity(D) · Buffer(D) where: - TaskCompletion(D) is the steady-state task completion rate (decreasing in D due to governance overhead) - Adaptivity(D) is the speed of adaptation to demand shocks (decreasing in D due to role-change friction) - Buffer(D) is max(0, 1 − D − λ_max) The product peaks at D* ∈ [0.30, 0.55], with the exact optimum depending on the weighting of the three factors. For equal weighting, D* ≈ 0.40. This aligns with the intuition that moderate governance produces the best outcomes: enough structure to prevent cascades, enough freedom to enable adaptation. At the optimal density, the system exhibits: - Task completion rate: 93.4% (vs. 97.1% at D = 0.10 and 78.2% at D = 0.70) - Perturbation recovery time: 23 ステップ (対 'D = 0.10' では 8 ステップ、'D = 0.70' では 450 ステップ) - 役割エントロピー: 2.1 (「log(10) = 2.3」のうち、多様化しているが均一ではない専門化を示します) - バッファマージン: 0.22 (脆弱な体制からの快適な予備)

11. Discussion

11.1 制御入力としてのガバナンス

The central message of this paper is that governance is not overhead — it is a control input. In the control-theory analogy, the influence matrix A_t represents the plant, the governance density D_t represents the damping input, the loop gain g_t = (1 − D_t)λ_max(A_t) is the exact contraction test, and the buffer margin δ_buffer = 1 − D_t − λ_max(A_t) is the operational reserve. Just as a control engineer distinguishes bare stability from healthy gain margin, an enterprise architect should distinguish exact convergence from buffered specialization. This perspective resolves a recurring debate in agentic company design: should governance be minimized (to maximize agent autonomy and speed) or maximized (to minimize risk)? The answer is neither. Governance should be calibrated to keep loop gain below 1 and, ideally, preserve a positive operating buffer. Too little governance allows cascading instability. Too much governance suppresses the adaptive capacity that justifies using agents in the first place.

11.2 Implications for Enterprise Architecture

The stability framework has several practical implications for enterprise architects designing agentic companies: Network Topology. The spectral radius λ_max is a property of the influence network. Densely connected networks with strong complementarities have high λ_max and therefore erode the operating buffer quickly. Architects can reduce λ_max by modularizing the organization into loosely coupled zones, standardizing interfaces between zones, and using the MARIA coordinate hierarchy to localize propagation. Governance Tuning. The constraint density D should be monitored and adjusted in real time, not set once at design time. Environmental changes alter the influence matrix, changing both loop gain and operating buffer. The MARIA OS gate engine provides the mechanism for this dynamic tuning. Scaling Laws. As the agent population N grows, the spectral radius of a random influence matrix scales as O(√N) for sparse networks and O(N) for dense networks. Larger agentic companies therefore need either more governance or substantially sparser influence topologies. The MARIA coordinate hierarchy provides a natural scaling mechanism by localizing most influence within zones and carefully curating inter-zone channels.

11.3 Relationship to Existing Frameworks

The framework connects to several established traditions: Game Theory. The stable role assignment ρ* is a Nash equilibrium of the role-selection game. The exact condition (1 − D)λ_max < 1 characterizes local convergence, while the buffered envelope λ_max < 1 − D gives a stronger, governance-oriented sufficient condition. Control Theory. The exact loop-gain test is the natural discrete-time contraction criterion for linearized feedback systems. The buffered envelope plays the role of a design margin rather than a bare feasibility threshold. Statistical Physics. The buffered boundary behaves like an order-disorder frontier, while the exact contraction boundary captures the onset of true amplification. The distinction mirrors the difference between nominal equilibrium and robust phase stability. Organizational Theory. The framework formalizes Ashby's Law of 必要な多様性: ガバナンスは、組織を過度に制約して停滞させることなく、エージェント間の影響によって生じる多様性を吸収するのに十分な制約構造を提供する必要があります。

11.4 制限事項

The framework has several limitations that suggest directions for future work: 1. Linear approximation. The exact stability law is derived from a linearization of the best-response dynamics near equilibrium. Near the contraction boundary, nonlinear effects become significant. 2. Stationary assumption. The influence matrix A_t is assumed to be slowly varying relative to the convergence time. In rapidly changing environments, both loop gain and buffer must be tracked continuously. 3. Homogeneous governance. The model assumes uniform governance density D across all agents. In practice, different agents face different governance intensities. Extending the framework to heterogeneous densities requires matrix-valued damping coefficients rather than a scalar D. 4. Role-space discreteness. The continuous analysis (smooth utilities, Jacobians) is an approximation to the discrete role-selection problem. For small role spaces (M < 5), discrete effects may dominate. 5. No learning dynamics. The framework assumes fixed utility functions. Incorporating online learning, exploration, and adaptive topology formation remains a major open problem.

11.5 Future Directions

Several extensions of the stability framework merit investigation: Adaptive Governance. Rather than setting D manually or through threshold-based rules, use online control to optimize both loop gain and buffer in real time. Heterogeneous Stability. Extend the framework to account for heterogeneous agents with different influence strengths, governance burdens, and utility functions. The generalized condition would involve the spectral radius of a damping-weighted influence matrix diag(1 − D_i) · A. Temporal Governance. Study how governance density should vary over the lifecycle of an agentic company. Early-stage exploration and mature operations may require different target buffers. Multi-Objective Stability. In practice, multiple stakeholders care about different kinds of stability (financial, operational, reputational, ethical). A multi-objective framework would require simultaneous buffer management across several influence matrices.

12. 結論

This paper has established a formal stability framework for agentic companies — enterprises in which autonomous AI agents self-organize into functional roles through decentralized utility maximization. The central result is a two-level criterion: - Exact contraction: (1 − D)λ_max(A) < 1 - Buffered specialization: λ_max(A) < 1 − D The first inequality determines whether the linearized organization actually contracts. The second identifies the portion of that stable region with usable governance reserve. Together they partition the design space into Stagnation, Buffered Specialization, Fragile Specialization, and Cascade. We have shown that this framework extends to multi-layer systems through the effective constraint density formula D_eff = 1 − ∏(1 − D_l). The MARIA OS implementation provides concrete tools for monitoring and controlling both loop gain and operating バッファ: ゲート エンジンは「D」を制御し、証拠層は高周波振動を減衰し、分析エンジンは「λ_max」、「g_t」、および「δ_buffer」を追跡し、ダッシュボードはこれらのメトリクスを人間のオペレーターに表示します。 111 のエージェントと 10 の役割タイプを使用した Planet-100 シミュレーションでの実験検証により、96.8% の分類精度でバッファリングされた動作境界が確認されました。最適なガバナンス密度範囲 D ∈ [0.30, 0.55] は、脆弱性に陥ることなく摂動を吸収するのに十分な余裕を備えた、80 ～ 200 の収束ステップ内でバッファされた特殊化を生成します。 さらに深い洞察は、統治と自治は対立する力ではないということです。ガバナンスは自律性を持続可能にする減衰を提供しますが、それは適応の余裕がなくなる点までに限られます。 AI ネイティブの組織を設計するエンタープライズ アーキテクトにとって、設計の処方箋は正確になりました。influence graph, estimate λ_max, keep loop gain below 1, and target a positive operating buffer. Stability is not the absence of change. It is the presence of convergence with reserve.
