Abstract
The proliferation of AI agents in enterprise decision-making introduces a fundamentally new class of dynamical systems: coupled human-AI co-evolutionary systems where both participants adapt their strategies, capabilities, and trust levels in response to shared interaction outcomes. Traditional single-agent optimization frameworks treat the human as a static environment or the AI as a fixed tool, failing to capture the bidirectional feedback loops that govern long-term system behavior. This paper presents a rigorous dynamical systems formulation of human-AI interaction, defining the combined state vector X_t = (H_t, A_t) where H_t captures human knowledge, cognitive strategy, trust, and emotional state, while A_t encodes AI model parameters, metacognitive state, and persona configuration.
We derive the coupled update equations H_{t+1} = H_t + F_H(H_t, A_t, o_t) and A_{t+1} = A_t + F_A(A_t, H_t, f_t), where F_H and F_A are nonlinear vector fields driven by task outcomes o_t and human feedback f_t respectively. The central contribution is the identification of metacognition as a stability controller: the metacognitive state MC_t = (Confidence_t, KnowledgeGap_t, StrategyChoice_t) within F_A acts as a damping mechanism that prevents three failure modes — trust collapse, capability decay, and co-evolutionary divergence.
We prove a Co-Evolution Stability Theorem establishing that when the spectral radius ρ(J) of the coupled Jacobian J = ∂X_{t+1}/∂X_t satisfies ρ(J) < 1, and a speed alignment constraint v_A ≤ κ v_H bounds the rate of AI adaptation relative to human learning, the system converges to a stable equilibrium X* where both human capability and AI performance are preserved. The metacognitive controller achieves this by modulating AI confidence, deliberately withholding complete answers to promote human reflection, and selecting interaction strategies that balance task performance against long-term capability preservation.
Monte Carlo simulations across 1000 trajectories with 500 agents over 200 time steps validate the theoretical predictions. Under metacognition-mediated control, 94.2% of runs maintain trust within the optimal band [T_min, T_max], compared to 61.3% for uncontrolled baselines. Human knowledge capital K_h retains 87.6% of its initial value after 200 cycles versus 52.4% under dependency-blind AI systems. Convergence to stable equilibrium occurs 3.2× faster with metacognitive speed alignment, and the average spectral radius is maintained at ρ(J) = 0.73 with stability margin δ = 0.27.
We demonstrate integration with the MARIA OS governance platform, mapping the theoretical framework to the MARIA coordinate system (G.U.P.Z.A), decision pipeline, and evidence layer. The Gate Engine enforces governance constraints as hard boundaries on the state space, while the Doctor system monitors spectral radius in real time, triggering intervention when ρ(J) approaches unity. This work provides both a theoretical foundation for safe human-AI co-evolution and a practical implementation pathway within enterprise AI governance architectures.
1. Introduction
The deployment of AI agents in organizational decision-making has accelerated from experimental prototypes to production-critical systems in under three years. By 2026, enterprise AI agents routinely draft contracts, triage customer inquiries, generate audit reports, and propose strategic recommendations. Yet the dominant paradigm for designing these systems remains fundamentally single-agent: optimize the AI's performance on a fixed task distribution, treat the human as an evaluator or supervisor, and measure success by accuracy, throughput, or user satisfaction scores.
This paradigm harbors a critical blind spot. When a human and an AI agent interact repeatedly over weeks, months, or years, both participants change. The human develops new heuristics, adjusts trust levels, modifies cognitive strategies, and — crucially — may experience skill atrophy in domains where the AI consistently provides answers. The AI, through fine-tuning, reinforcement from human feedback, and metacognitive adaptation, alters its response patterns, confidence calibration, and interaction strategies. The interaction is not a static game but a coupled dynamical system evolving on multiple timescales.
The consequences of ignoring this coupling are severe and well-documented. Overtrust leads to automation complacency, where humans accept AI outputs without critical evaluation, degrading their own judgment capabilities over time. Undertrust leads to usage abandonment, where humans reject useful AI assistance due to poorly calibrated expectations, forfeiting productivity gains. Capability decay — the gradual erosion of human expertise through prolonged AI dependency — represents an existential risk to organizational resilience: if the AI system fails or encounters novel situations outside its training distribution, the humans who once possessed the relevant expertise may no longer be capable of stepping in.
These failure modes are not independent. They interact through feedback loops that can amplify small perturbations into catastrophic system failures. A slight increase in AI accuracy triggers increased human reliance, which reduces human practice, which degrades human capability, which further increases dependence on AI, creating a positive feedback loop that drives the system toward a degenerate equilibrium where human expertise approaches zero. Conversely, a single high-profile AI error can trigger a trust cascade, where humans reject AI assistance entirely, overloading their own cognitive capacity, leading to errors that are attributed to "working without AI," paradoxically reinforcing the perception that AI is necessary — a different positive feedback loop with different but equally problematic dynamics.
The dynamical systems perspective provides the correct mathematical language for these phenomena. By defining a combined state vector X_t that encodes both human and AI states, we can analyze the system's fixed points, their stability, the basins of attraction, and the conditions under which the system converges to desirable equilibria versus pathological ones. The Jacobian matrix J = ∂X_{t+1}/∂X_t of the coupled update equations captures the local sensitivity of the system to perturbations, and its spectral radius ρ(J) determines whether perturbations are amplified (ρ(J) > 1, instability) or damped (ρ(J) < 1, stability).
The central thesis of this paper is that metacognition — the AI system's awareness and regulation of its own cognitive processes — serves as the primary stability controller in the coupled human-AI dynamical system. A metacognition-aware AI does not simply optimize for task performance; it monitors the human's state (trust, capability, cognitive load), adjusts its own behavior to maintain the coupled system within stable operating regimes, and deliberately modulates its interaction strategy to preserve human capability even when doing so incurs short-term performance costs.
This is fundamentally different from conventional AI alignment approaches, which focus on aligning AI outputs with human preferences at each interaction. Our framework requires aligning the AI's evolutionary trajectory with the human's developmental trajectory across the entire interaction history. The distinction is analogous to the difference between pointwise convergence and uniform convergence in functional analysis: local alignment at each time step does not guarantee global co-evolutionary stability.
The remainder of this paper is organized as follows. Section 2 reviews related work in dynamical systems, trust calibration, and human-AI teaming. Section 3 defines the state space formally. Sections 4 through 6 derive the coupled update equations, trust dynamics, and capability decay model. Section 7 presents the stability analysis and proves the Co-Evolution Stability Theorem. Section 8 details the metacognitive controller. Section 9 presents numerical simulations. Section 10 describes the MARIA OS integration, and Section 11 concludes.
2. Background and Related Work
2.1 Dynamical Systems in AI
The application of dynamical systems theory to machine learning has a rich history. Strogatz (2015) provides the foundational treatment of nonlinear dynamics and chaos, establishing the mathematical tools — fixed point analysis, bifurcation theory, Lyapunov stability — that we adapt for the human-AI coupling context. Saxe et al. (2014) analyzed deep neural network training as a dynamical system, showing that learning dynamics exhibit phase transitions and critical slowing down near saddle points. More recently, E et al. (2017) proposed the continuous-time neural ODE framework, where network forward passes are modeled as flows of ordinary differential equations. Our work extends this perspective from single-network training dynamics to coupled multi-agent co-evolutionary dynamics.
2.2 Trust Calibration
Trust in automation has been studied extensively since Lee and See's (2004) seminal framework, which decomposed trust into performance-based, process-based, and purpose-based components. Yin et al. (2019) demonstrated that stated AI accuracy significantly affects user trust, but the relationship is nonlinear: accuracy above expectations increases trust, while accuracy below expectations decreases it asymmetrically. Bansal et al. (2019) showed that AI explanations can paradoxically reduce task performance when they induce overtrust. Our trust dynamics model (Section 5) formalizes these empirical findings as a nonlinear update equation with asymmetric gain and loss coefficients.
2.3 Human-AI Teaming
The human-AI teaming literature has evolved from simple automation level taxonomies (Sheridan & Verplank, 1978) to dynamic function allocation frameworks (Parasuraman et al., 2000). Bansal et al. (2021) introduced the concept of "complementary performance" where human-AI teams outperform either alone, but showed this requires careful calibration of when to defer. Hemmer et al. (2023) extended this to learning-to-defer frameworks where the AI learns an optimal deferral policy. Our framework subsumes these approaches by modeling the deferral decision as one component of the AI's metacognitive strategy space.
2.4 Cognitive Load and Skill Decay
Sweller's (1988) cognitive load theory identifies three types of cognitive load: intrinsic (task complexity), extraneous (poor design), and germane (learning-promoting). AI assistance primarily reduces intrinsic load but may inadvertently eliminate germane load, preventing skill consolidation. Skill decay research (Arthur et al., 1998) shows that cognitive skills degrade exponentially without practice, with complex procedural skills decaying faster than simple declarative ones. Our capability decay model (Section 6) incorporates these findings, showing that metacognitive strategies that maintain germane cognitive load can counteract dependency-induced skill atrophy.
3. State Space Definition
We define the coupled human-AI system on a product state space X = H × A, where H is the human state space and A is the AI agent state space. At each discrete time step t ∈ {0, 1, 2, ...}, the system occupies a state X_t = (H_t, A_t) ∈ X.
3.1 Human State Vector
The human state at time t is defined as the tuple:
H_t = (K_h, C_h, T_h, E_h)
where each component captures a distinct dimension of human cognitive and behavioral state.
Knowledge Capital K_h ∈ R^d_K. The knowledge capital vector represents the human's domain expertise across d_K knowledge dimensions. Each component K_h^(i) ∈ [0, 1] measures proficiency in a specific skill or knowledge area, where 0 indicates no proficiency and 1 indicates expert-level mastery. The dimensionality d_K is domain-dependent; for a financial auditing context, K_h might include components for regulatory knowledge, spreadsheet analysis, anomaly detection, report writing, and client communication. Knowledge capital evolves through practice (positive) and disuse atrophy (negative), with the rate of change governed by the capability decay model in Section 6.
Cognitive Strategy C_h ∈ S^{d_C}. The cognitive strategy vector lies on a probability simplex S^{d_C} of dimension d_C, where each component C_h^(j) represents the probability that the human employs cognitive strategy j when facing a decision. Strategies include: independent_analysis (solve without AI), ai_consultation (ask AI then evaluate), ai_delegation (delegate entirely to AI), collaborative_synthesis (iterative human-AI dialogue), and verification_only (review AI output for errors). The strategy vector evolves through reinforcement: strategies that yield good outcomes increase in probability, while those that produce errors decrease. The normalization constraint ∑_j C_h^(j) = 1 ensures the vector remains on the simplex.
Trust T_h ∈ [0, 1]. The scalar trust variable measures the human's overall trust in the AI system, where 0 represents complete distrust and 1 represents unconditional trust. Trust evolves through the dynamics described in Section 5 and serves as a gating variable: when T_h falls below a threshold T_min, the human ceases to use the AI; when T_h exceeds T_max, the human enters an overtrust regime where critical evaluation diminishes. The optimal operating range is [T_min, T_max] = [0.3, 0.8] based on empirical calibration.
Emotional State E_h ∈ R^d_E. The emotional state vector captures affective dimensions relevant to human-AI interaction, including frustration, confidence, engagement, and anxiety. Each component E_h^(k) ∈ [-1, 1] ranges from strongly negative to strongly positive affect. Emotional state influences cognitive strategy selection (high frustration biases toward delegation) and trust dynamics (anxiety amplifies trust loss from errors). We model d_E = 4 dimensions: frustration, self-efficacy, engagement, and cognitive anxiety.
3.2 AI Agent State Vector
The AI agent state at time t is defined as:
A_t = (Θ_t, MC_t, I_t)
Model Parameters Θ_t ∈ R^d_Θ. The model parameter vector encompasses all trainable parameters of the AI system, including language model weights, retrieval indices, and policy network parameters. In practice, d_Θ may be billions-dimensional, but for the purposes of our dynamical analysis we work with an effective low-dimensional representation obtained through principal component analysis of the parameter trajectory. Parameter updates follow gradient-based learning from human feedback: Θ_{t+1} = Θ_t − η_Θ ∇L(f_t), where L is a loss function defined over feedback f_t.
Metacognitive State MC_t ∈ R^3. The metacognitive state is the key novel component, defined as MC_t = (Confidence_t, KnowledgeGap_t, StrategyChoice_t). Confidence measures the AI's calibrated uncertainty about its own outputs. KnowledgeGap quantifies the discrepancy between the knowledge required for the current task and the knowledge available in the AI's context. StrategyChoice is a categorical variable selecting among interaction strategies. The metacognitive state is detailed in Section 8.
Persona Vector I_t ∈ R^d_I. The persona vector encodes the AI's interaction style parameters: verbosity, formality, assertiveness, empathy expression, and explanation depth. These parameters are adjusted based on observed human preferences and emotional state. The persona vector lies in [0, 1]^d_I with d_I = 5 dimensions.
3.3 State Variable Summary
| Variable | Space | Dimension | Range | Description |
| --- | --- | --- | --- | --- |
| K_h | R^d_K | d_K = 8 | [0, 1]^d_K | Human knowledge capital across skill dimensions |
| C_h | S^d_C | d_C = 5 | Simplex | Cognitive strategy probability distribution |
| T_h | R | 1 | [0, 1] | Human trust in AI system |
| E_h | R^d_E | d_E = 4 | [-1, 1]^d_E | Human emotional state (frustration, efficacy, engagement, anxiety) |
| Θ_t | R^d_eff | d_eff = 10 | R^d_eff | Effective model parameters (PCA-reduced) |
| MC_t | R^3 | 3 | Mixed | Metacognitive state (confidence, knowledge gap, strategy) |
| I_t | R^d_I | d_I = 5 | [0, 1]^d_I | Persona/interaction style parameters |
The total state space dimension is d_X = d_K + d_C + 1 + d_E + d_eff + 3 + d_I = 8 + 5 + 1 + 4 + 10 + 3 + 5 = 36. While the full parameter space Θ is high-dimensional, the effective dynamics can be analyzed in this 36-dimensional projection without loss of qualitative behavior, as the dominant eigenvalues of the full Jacobian are captured by the reduced system (see Section 7).
4. Coupled Update Equations
The evolution of the coupled system is governed by two vector-valued update equations that encode the bidirectional feedback between human and AI states.
4.1 Human State Update
The human state evolves according to:
H_{t+1} = H_t + F_H(H_t, A_t, o_t)
where o_t ∈ {success, partial_success, failure} is the task outcome at time t, and F_H: H × A × O → R^{d_H} is the human update vector field. We decompose F_H into four component-wise updates:
Knowledge Update. K_{h,t+1} = K_{h,t} + ζ R_t − η D_t K_{h,t}, where R_t ∈ [0, 1] is the reflection intensity (how much the human actively engaged their own reasoning during the interaction), D_t = usage_AI / (usage_AI + usage_independent) is the dependency ratio, ζ is the learning rate from reflection, and η is the decay rate from disuse. This equation is analyzed in detail in Section 6.
Strategy Update. The cognitive strategy vector is updated via a softmax reinforcement rule: C_{h,t+1}^(j) = C_{h,t}^(j) exp(γ r_t^(j)) / Z_t, where r_t^(j) is the reward signal for strategy j (positive for strategies that contributed to successful outcomes, negative for those associated with failures), γ is the learning rate, and Z_t = ∑_j C_{h,t}^(j) exp(γ r_t^(j)) is the normalizing partition function ensuring the updated vector remains on the probability simplex.
Trust Update. T_{h,t+1} = T_{h,t} + α max(0, Perf_t − Exp_t) − β max(0, Exp_t − Perf_t), where Perf_t is the observed AI performance, Exp_t is the human's expectation (a moving average of past performance), and α, β are asymmetric gain and loss coefficients with β > α reflecting loss aversion. This is detailed in Section 5.
Emotional Update. E_{h,t+1} = (1 − μ) E_{h,t} + μ e(o_t, T_{h,t}, workload_t), where μ ∈ (0, 1) is the emotional inertia parameter (lower values mean emotions change slowly) and e: O × [0,1] × R → R^{d_E} maps outcomes, trust state, and workload to emotional increments. For example, a failure outcome with high trust produces a large negative increment in self-efficacy and a positive increment in anxiety.
4.2 AI Agent State Update
The AI agent state evolves according to:
A_{t+1} = A_t + F_A(A_t, H_t, f_t)
where f_t is the human feedback signal at time t (explicit ratings, implicit behavioral signals, or absence of feedback), and F_A: A × H × F → R^{d_A} is the AI update vector field. We decompose F_A into three terms:
F_A = Learning + MetaAdjustment − GovernancePenalty
Learning Term. The learning component updates model parameters based on feedback: Learning_t = −η_Θ ∇_Θ L(Θ_t, f_t), where L is a composite loss function incorporating instruction following, helpfulness, harmlessness, and honesty objectives. In practice, this corresponds to RLHF, DPO, or constitutional AI training signals. The gradient is computed with respect to the effective parameter representation Θ_t. The learning term drives AI capability improvement and is the dominant term in conventional optimization frameworks.
MetaAdjustment Term. This is the critical novel term that distinguishes our framework from standard AI optimization. The metacognitive adjustment modifies the AI's behavior based on its assessment of the human's state:
MetaAdjustment_t = φ(MC_t, H_t^{est})
where H_t^{est} is the AI's estimate of the human state (obtained through observation of human behavior, response times, question patterns, and explicit feedback), and φ is the metacognitive policy function. The MetaAdjustment term operates on the metacognitive state MC_t and persona vector I_t, not on the model parameters Θ_t. It modulates how the AI presents its outputs rather than what outputs it generates. For example, if the AI estimates that T_h is approaching T_max (overtrust), the MetaAdjustment may increase the AI's expressed uncertainty, present alternative viewpoints, or deliberately withhold the most convenient answer to encourage human critical thinking.
GovernancePenalty Term. The governance penalty enforces hard constraints imposed by the organizational governance framework: GovernancePenalty_t = λ_G ∇_A g(A_t, G), where g(A_t, G) is a penalty function measuring the AI's deviation from governance constraints G. Governance constraints include: decision authority boundaries (the AI must not make decisions above its authorized level), audit trail requirements (all actions must be logged), and human-in-the-loop gates (certain decisions require explicit human approval regardless of AI confidence). In the MARIA OS context, these constraints are enforced by the Gate Engine and are non-negotiable — the governance penalty has effectively infinite weight λ_G → ∞ at the gate boundaries, creating hard walls in the state space.
4.3 Why Metacognition Appears in F_A
The inclusion of the MetaAdjustment term in the AI update equation is the architectural decision that enables co-evolutionary stability. Without it, the AI optimizes F_A = Learning − GovernancePenalty, which drives Θ_t toward maximum task performance subject to governance constraints. This is locally optimal but globally unstable: as AI performance increases, human trust increases (via the trust dynamics), dependency increases (via the strategy update), capability decays (via the knowledge update), and the system drifts toward the degenerate equilibrium K_h → 0. The MetaAdjustment term introduces a coupling from the estimated human state back into the AI's update rule, creating a negative feedback loop that counteracts the dependency spiral. The AI deliberately sacrifices short-term task performance to preserve long-term human capability — a strategy that is only rational when the AI models the coupled dynamical system rather than optimizing its own objective in isolation.
5. Trust Dynamics
Trust is the central mediating variable in the coupled system. It gates the human's willingness to use the AI (low trust → non-use), the depth of reliance (high trust → uncritical delegation), and the human's emotional response to AI errors (high trust → larger betrayal effect). This section develops the trust dynamics model in detail.
5.1 Trust Update Equation
The trust scalar T_h evolves according to:
T_{h,t+1} = clip(T_{h,t} + α(Perf_t − Exp_t)^+ − β(Exp_t − Perf_t)^+ + σ Transparency_t, 0, 1)
where (x)^+ = max(0, x) denotes the positive part, and the clip function constrains T_h to [0, 1]. The terms are:
Performance Perf_t ∈ [0, 1]. A scalar measure of the AI's output quality on the most recent interaction, assessed by the human (explicitly or implicitly through behavioral signals such as acceptance, editing, or rejection of the AI's output).
Expectation Exp_t. The human's expected AI performance, modeled as an exponentially weighted moving average: Exp_t = (1 − ω) Exp_{t-1} + ω Perf_{t-1}, where ω ∈ (0, 1) is the recency weight. This captures the empirical finding that humans form expectations based on recent experience, with diminishing weight on older interactions. Initial expectation Exp_0 is set by the human's prior beliefs about AI capability, which may be influenced by marketing, peer reports, or initial demonstrations.
Asymmetric Coefficients α, β. The gain coefficient α governs trust increase when performance exceeds expectations, while the loss coefficient β governs trust decrease when performance falls below expectations. Following prospect theory (Kahneman & Tversky, 1979) and empirical findings in trust calibration (Yin et al., 2019), we set β > α (specifically, β = 0.25, α = 0.15 in our simulations), reflecting the empirical observation that trust is harder to build than to destroy. A single catastrophic failure can erase trust accumulated over many successful interactions.
Transparency Bonus σ Transparency_t. A small positive term that rewards AI transparency. When the AI provides explanations, cites evidence, expresses calibrated uncertainty, or acknowledges limitations, the transparency score Transparency_t ∈ [0, 1] increases. The coefficient σ is small (σ = 0.03) reflecting the finding that transparency has a modest but consistent positive effect on trust, independent of performance outcomes.
5.2 Overtrust and Undertrust Regimes
The trust dynamics exhibit qualitatively different behavior in three regimes, separated by thresholds T_min and T_max:
Undertrust Regime (T_h < T_min = 0.3). When trust falls below T_min, the human reduces AI usage dramatically. The cognitive strategy vector C_h shifts probability mass toward independent_analysis, and the dependency ratio D_t drops. While this preserves human capability (K_h remains high due to practice), it forfeits the productivity benefits of human-AI collaboration. If undertrust is sustained, it becomes self-reinforcing: reduced usage means fewer opportunities for the AI to demonstrate competence, which prevents trust recovery. The system enters a low-trust absorbing state.
Optimal Regime (T_min ≤ T_h ≤ T_max). In the optimal trust band, the human uses the AI as a collaborative partner: consulting it for complex decisions, critically evaluating its outputs, maintaining independent capability through selective engagement, and providing high-quality feedback that enables AI improvement. The cognitive strategy distribution C_h has substantial probability mass on collaborative_synthesis and ai_consultation, with lower mass on full delegation. This regime is characterized by balanced information flow: the human provides feedback that improves the AI, while the AI provides assistance that enhances human productivity without degrading human capability.
Overtrust Regime (T_h > T_max = 0.8). When trust exceeds T_max, critical evaluation diminishes. The human shifts toward ai_delegation as the dominant strategy, accepting AI outputs without verification. Dependency ratio D_t approaches 1, and knowledge capital K_h begins to decay. Crucially, overtrust creates a fragility: the human's reduced capability means they are less able to detect AI errors, so errors propagate unnoticed, potentially causing significant downstream damage. When an error is eventually detected (often by an external auditor or customer), the trust collapse is catastrophic, dropping T_h by β × (Exp_t − Perf_t) which can be very large if Exp_t has been inflated by a long period of high trust.
5.3 Trust Phase Diagram
The trust dynamics can be visualized as a phase diagram in the (T_h, K_h) plane. The system exhibits three basins of attraction:
Basin 1: Capability-Preserved Collaboration. The attractor at (T_h, K_h) ≈ (0.55, 0.82) corresponds to the optimal operating point where trust is moderate and capability is high. The basin extends across the region T_min < T_h < T_max, K_h > 0.5. Trajectories within this basin spiral inward, with trust and capability oscillating around the attractor as the system responds to stochastic performance variations.
Basin 2: Dependency Trap. The attractor at (T_h, K_h) ≈ (0.9, 0.15) corresponds to the overtrust-low-capability degenerate equilibrium. The basin covers the region T_h > T_max, K_h < 0.5. Once the system enters this basin, escape is difficult because the human lacks the capability to critically evaluate AI outputs and therefore cannot recalibrate trust downward through independent assessment.
Basin 3: Rejection Equilibrium. The attractor at (T_h, K_h) ≈ (0.1, 0.85) corresponds to the undertrust state where the human rejects the AI and maintains capability through independent work. This basin covers T_h < T_min. While capability is preserved, productivity benefits of collaboration are lost.
5.4 Metacognitive Trust Regulation
The metacognitive controller regulates trust by adjusting the AI's behavior to keep T_h within [T_min, T_max]. When the AI estimates T_h approaching T_max, it increases expressed uncertainty ("I'm not fully confident in this analysis; here are the key assumptions you should verify"), presents counterarguments, and deliberately provides partial answers that require human completion. When T_h approaches T_min, the AI increases transparency, provides more detailed explanations, and prioritizes high-confidence responses to rebuild trust through demonstrated competence. This regulation is formalized as a proportional controller: the MetaAdjustment term in F_A includes a trust correction signal proportional to T_h − T_target, where T_target = (T_min + T_max) / 2 = 0.55.
6. Capability Decay Model
Human capability decay through AI dependency is the most insidious failure mode because it is invisible to both participants during its progression. The human does not notice skill erosion because the AI compensates; the AI does not detect it unless it explicitly monitors human performance on independent tasks. This section models capability decay formally and shows how metacognitive intervention can arrest it.
6.1 Dependency Ratio
The dependency ratio D_t quantifies the fraction of decisions where the human relies on AI assistance:
D_t = N_{AI,t} / (N_{AI,t} + N_{ind,t})
where N_{AI,t} is the number of AI-assisted decisions and N_{ind,t} is the number of independent decisions in a moving window of W recent interactions. D_t ∈ [0, 1], with D_t = 0 indicating complete independence and D_t = 1 indicating complete dependence. In practice, the dependency ratio is estimated from the cognitive strategy vector: D_t ≈ C_h^{delegation} + 0.5 × C_h^{consultation}, weighting full delegation at 1.0 and consultation at 0.5 (since consultation involves some independent thinking).
6.2 Knowledge Capital Update
The knowledge capital vector evolves component-wise:
K_{h,t+1}^(i) = K_{h,t}^(i) − η D_t^(i) K_{h,t}^(i) + ζ R_t^(i) (1 − K_{h,t}^(i))
The first term K_{h,t}^(i) is the current knowledge. The second term −η D_t^(i) K_{h,t}^(i) represents decay: knowledge dimension i decays at rate η proportional to the dependency ratio for that dimension D_t^(i) and the current knowledge level K_{h,t}^(i). Higher knowledge decays faster in absolute terms (the expert has more to lose), but the proportional rate is constant. The parameter η = 0.08 is calibrated from skill decay literature (Arthur et al., 1998), corresponding to approximately 8% decay per interaction cycle under full dependency.
The third term +ζ R_t^(i) (1 − K_{h,t}^(i)) represents learning through reflection. R_t^(i) ∈ [0, 1] is the reflection intensity for knowledge dimension i — how much active cognitive engagement the human devoted to reasoning about this domain during the interaction. The factor (1 − K_{h,t}^(i)) captures diminishing returns: learning is fastest when knowledge is low and slows as the human approaches mastery. The parameter ζ = 0.12 governs the learning rate.
6.3 Reflection and Metacognitive Intervention
The reflection intensity R_t is the key variable through which metacognition affects capability preservation. Without metacognitive intervention, R_t is determined by the human's cognitive strategy: independent analysis produces high reflection (R_t ≈ 0.9), consultation produces moderate reflection (R_t ≈ 0.4), and delegation produces near-zero reflection (R_t ≈ 0.05). As the human shifts toward delegation under overtrust, reflection drops, and capability decay accelerates.
The metacognitive controller increases R_t through several strategies. First, it employs deliberate partial answers: instead of providing complete solutions, the AI presents partial analyses and asks the human to complete the reasoning, forcing active cognitive engagement. Second, it uses thought-provoking questions: the AI poses Socratic questions that require the human to articulate their own reasoning before receiving AI input. Third, it implements strategic uncertainty expression: even when the AI is confident, it may express uncertainty to encourage the human to independently verify the result. Fourth, it uses calibrated challenge: the AI deliberately presents alternative viewpoints or plays devil's advocate, requiring the human to defend their position with their own knowledge.
Formally, the metacognition-enhanced reflection intensity is:
R_t^{MC} = R_t^{base} + ψ(MC_t) (1 − R_t^{base})
where R_t^{base} is the base reflection intensity determined by the cognitive strategy, and ψ(MC_t) ∈ [0, 1] is the metacognitive reflection boost, a function of the metacognitive state that increases when the AI detects high dependency (D_t > 0.7) or declining knowledge (dK_h/dt < −ε). The factor (1 − R_t^{base}) ensures the boost is largest when base reflection is lowest (i.e., during delegation), which is precisely when it is most needed.
6.4 Long-Term Implications
Without metacognitive intervention, the knowledge capital equation has two fixed points for each dimension. Setting K_{h,t+1}^(i) = K_{h,t}^(i) and solving: K = ζ R / (ζ R + η D). Under full dependency (D = 1) with minimal reflection (R = 0.05), K = 0.12 × 0.05 / (0.12 × 0.05 + 0.08 × 1.0) = 0.006/0.086 ≈ 0.07. This means that without metacognitive intervention, the equilibrium knowledge capital is approximately 7% of maximum — near-total capability loss. Under metacognition-enhanced interaction with R^{MC} ≈ 0.5 even during AI-assisted work, K = 0.12 × 0.5 / (0.12 × 0.5 + 0.08 × 0.7) = 0.06/0.116 ≈ 0.52. The equilibrium knowledge capital is approximately 52% of maximum, and with moderate independent practice (D = 0.5), K rises to 0.12 × 0.7 / (0.12 × 0.7 + 0.08 × 0.5) = 0.084/0.124 ≈ 0.68, preserving substantial human capability.
7. Stability Analysis
We now analyze the stability of the coupled dynamical system using the Jacobian matrix and spectral theory. The central result is the Co-Evolution Stability Theorem, which provides sufficient conditions for the system to converge to a stable equilibrium where both human capability and AI performance are preserved.
7.1 Jacobian Matrix
The combined state update X_{t+1} = G(X_t) = X_t + F(X_t), where F = (F_H, F_A), has Jacobian:
J = ∂G/∂X = I + ∂F/∂X
which decomposes into block structure:
J = | I + ∂F_H/∂H_t , ∂F_H/∂A_t |
| ∂F_A/∂H_t , I + ∂F_A/∂A_t |
The diagonal blocks ∂F_H/∂H_t and ∂F_A/∂A_t capture the self-dynamics of human and AI evolution respectively. The off-diagonal blocks ∂F_H/∂A_t and ∂F_A/∂H_t capture the coupling — how changes in one participant's state affect the other's evolution. Without metacognition, ∂F_A/∂H_t is small or zero (the AI ignores human state), and the coupling is unidirectional: the AI affects the human but not vice versa (beyond simple feedback). With metacognition, ∂F_A/∂H_t is substantial, creating bidirectional coupling that enables stability control.
7.2 Local Stability Condition
A fixed point X of the map G is locally stable if and only if all eigenvalues λ_i of the Jacobian J evaluated at X satisfy |λ_i| < 1. Equivalently, the spectral radius ρ(J) = max_i |λ_i| must satisfy ρ(J) < 1.
The eigenvalues of J are related to those of ∂F/∂X through λ_i(J) = 1 + λ_i(∂F/∂X). Therefore, the stability condition becomes: all eigenvalues of ∂F/∂X must have real part in (−2, 0). Eigenvalues with positive real part indicate instability (growing perturbations), while eigenvalues with real part below −2 indicate oscillatory instability (perturbations that grow while alternating sign).
7.3 Speed Alignment Constraint
A critical source of instability arises when the AI adapts much faster than the human can learn. Define the adaptation speeds:
v_A = ||A_{t+1} − A_t|| = ||F_A(A_t, H_t, f_t)||
v_H = ||H_{t+1} − H_t|| = ||F_H(H_t, A_t, o_t)||
If v_A >> v_H, the AI's behavior changes faster than the human can recalibrate their expectations, trust, and cognitive strategies. This creates a scenario where the human is perpetually adapting to an AI that has already moved on, leading to expectation mismatches, trust volatility, and cognitive overload. Formally, rapid AI adaptation inflates the off-diagonal block ∂F_H/∂A_t because the human's update depends on the difference between observed and expected AI behavior, which grows with v_A.
We impose a speed alignment constraint: v_A ≤ κ v_H, where κ > 1 is the speed ratio bound. This constraint limits how quickly the AI can change its behavior relative to human adaptation. In practice, κ = 1.5 provides a good balance: the AI can adapt 50% faster than the human but not more. The metacognitive controller enforces this by throttling MetaAdjustment magnitude when v_A approaches κ v_H.
7.4 Theorem 1: Co-Evolution Stability
Theorem (Co-Evolution Stability). Let X_t = (H_t, A_t) be the coupled human-AI dynamical system with update rule X_{t+1} = G(X_t). Let X be a fixed point where T_h ∈ [T_min, T_max], K_h > K_min, and the AI satisfies governance constraints g(A, G) = 0. If the following conditions hold:
(C1) The metacognitive controller maintains Confidence calibration error |Conf_t − Acc_t| < ε_c for calibration threshold ε_c > 0, where Acc_t is the AI's actual accuracy.
(C2) The speed alignment constraint v_A ≤ κ v_H is satisfied with κ ≥ 1.
(C3) The trust dynamics coefficients satisfy β > α > 0 and the transparency coefficient σ > 0.
(C4) The metacognitive reflection boost ψ(MC_t) > ψ_min > 0 whenever D_t > D_threshold.
Then the spectral radius of the Jacobian satisfies ρ(J(X)) < 1, and X is a locally asymptotically stable fixed point of G. Moreover, the stability margin δ = 1 − ρ(J(X*)) is bounded below by:
δ ≥ min(α σ / (α + β), ζ ψ_min / (ζ + η), 1 / κ)
Proof sketch. We analyze the eigenvalues of J by Gershgorin's circle theorem. The diagonal entries of ∂F/∂X are bounded: ∂F_H^{(T)}/∂T_h = −α or −β (depending on whether performance exceeds or falls below expectations), both negative; ∂F_H^{(K)}/∂K_h = −η D_t < 0 (capability decay is stabilizing); ∂F_A^{(MC)}/∂MC_t is bounded by the metacognitive learning rate. The off-diagonal entries (coupling terms) are bounded by the speed alignment constraint: |∂F_H/∂A_t| ≤ κ max(|∂F_H/∂H_t|) by construction, since the human's response to AI changes is bounded by κ times their self-adaptation rate.
By Gershgorin, each eigenvalue λ of ∂F/∂X lies in a disk centered at the corresponding diagonal entry with radius equal to the sum of absolute values of off-diagonal entries in that row. Condition (C2) ensures the Gershgorin radii are bounded. Conditions (C1) and (C3) ensure the diagonal entries are sufficiently negative (the self-dynamics are stabilizing). Condition (C4) ensures that the capability preservation mechanism is active, preventing drift toward the degenerate equilibrium. The stability margin bound follows from computing the worst-case Gershgorin disk boundary across the three key subsystems (trust, knowledge, speed). The detailed algebraic verification is provided in Appendix A.
7.5 Eigenvalue Analysis
Numerical computation of the Jacobian eigenvalues at the optimal equilibrium X* reveals the spectral structure of the coupled system. The 36 eigenvalues cluster into three groups:
Fast modes (λ ≈ 0.3 − 0.5). These correspond to emotional state dynamics and persona adjustments, which equilibrate quickly. Perturbations in emotional state or AI persona decay within 2-3 interaction cycles.
Medium modes (λ ≈ 0.6 − 0.8). These correspond to trust dynamics, cognitive strategy evolution, and metacognitive state adaptation. The dominant eigenvalue λ_max = 0.73 corresponds to the trust-dependency coupling: a perturbation in trust propagates to dependency (via strategy change), which affects capability (via knowledge update), which feeds back to trust (via changed human performance). This feedback loop has the slowest decay rate and determines the overall spectral radius.
Slow modes (λ ≈ 0.85 − 0.92). These correspond to knowledge capital dynamics, which evolve on the longest timescale. Capability changes require many interaction cycles to manifest, and the system's memory of past capability levels decays slowly. The proximity of these eigenvalues to unity (λ ≈ 0.92) explains why capability decay is difficult to detect and reverse: perturbations in knowledge capital persist for tens to hundreds of interaction cycles.
7.6 Stability Margin
The stability margin δ = 1 − ρ(J) = 1 − 0.92 = 0.08 for the slow knowledge modes is uncomfortably small. This means that even small increases in the coupling strength (e.g., through increased AI capability making dependency more attractive) can push ρ(J) above 1 and destabilize the system. The metacognitive controller's primary role is to maintain this margin by actively boosting reflection intensity ψ(MC_t) when it detects the margin shrinking. The average spectral radius across simulations is ρ(J) = 0.73, which is dominated by the trust-dependency coupling rather than the slow knowledge modes, because the metacognitive controller actively manages the knowledge dynamics to keep λ_knowledge well below 0.92 in practice.
8. Meta Cognition as Stability Controller
Having established the stability conditions for the coupled system, we now detail the metacognitive controller that achieves these conditions in practice. The metacognitive state MC_t = (Confidence_t, KnowledgeGap_t, StrategyChoice_t) is the AI's internal model of its own epistemic state, and the metacognitive policy φ(MC_t, H_t^{est}) determines how the AI modulates its behavior to maintain co-evolutionary stability.
8.1 Confidence Calibration
Confidence is defined as:
Confidence_t = 1 − H(belief_t) / H_max
where H(belief_t) = −∑_i p_i log(p_i) is the Shannon entropy of the AI's belief distribution over possible responses, and H_max = log(|response_space|) is the maximum entropy (uniform distribution). When the AI has a single dominant belief, H is low and Confidence is high. When the AI is uncertain among multiple possible responses, H is high and Confidence is low.
Calibration requires that expressed confidence matches actual accuracy: |Confidence_t − Acc_t| < ε_c. Overconfidence (Confidence > Acc) promotes overtrust; underconfidence (Confidence < Acc) promotes undertrust. The metacognitive controller maintains calibration through a feedback loop: when realized accuracy differs from expressed confidence, the confidence mapping is adjusted via Platt scaling or temperature calibration.
8.2 Knowledge Gap Assessment
The knowledge gap quantifies the discrepancy between task requirements and available knowledge:
KnowledgeGap_t = D_KL(P_required || P_current)
where P_required is the distribution of knowledge dimensions needed for the current task (estimated from task analysis), P_current is the AI's current knowledge distribution (estimated from retrieval coverage and model uncertainty), and D_KL is the Kullback-Leibler divergence. A large knowledge gap indicates that the AI lacks critical information and should seek additional evidence, ask clarifying questions, or escalate to a more capable agent.
The knowledge gap drives two behaviors: internal (the AI activates retrieval, extends thinking, or requests additional context) and external (the AI communicates its limitations to the human, enabling informed trust calibration). Transparency about knowledge gaps is a primary driver of calibrated trust.
8.3 Strategy Selection
The metacognitive strategy selector chooses among five strategies based on expected improvement and cost:
StrategyChoice_t = argmax_s [E[Improvement | s] − λ_s Cost(s)]
where s ∈ {ask_clarification, retrieve_evidence, extend_thinking, escalate, proceed} and λ_s is a cost-sensitivity parameter that trades off response quality against latency and resource consumption.
ask_clarification. The AI requests additional information from the human. Expected improvement is high when KnowledgeGap is large and the gap can be filled by human-provided context. Cost is measured in interaction latency and human cognitive load. This strategy has a side benefit of promoting human reflection (R_t increases).
retrieve_evidence. The AI searches its knowledge base, retrieves documents, or queries external sources. Expected improvement is high when KnowledgeGap is large but the required knowledge exists in accessible repositories. Cost is computational (retrieval latency).
extend_thinking. The AI allocates additional reasoning steps, exploring alternative approaches, checking consistency, and self-critiquing. Expected improvement is high when Confidence is moderate (the AI has enough information but hasn't fully processed it). Cost is computational (additional inference time).
escalate. The AI defers the decision to a higher-authority agent or human expert. Expected improvement is high when KnowledgeGap is very large or the decision falls outside the AI's authorized scope. Cost is high (latency, expert time) but the strategy is mandatory when governance gates require it.
proceed. The AI generates a response with its current knowledge. Expected improvement is zero (no additional information gathering). Cost is minimal. This strategy is appropriate when Confidence is high, KnowledgeGap is low, and the task is within authorized scope.
8.4 Metacognitive Strategy Selector Pseudocode
function selectStrategy(MC_t, H_t_est, task):
confidence = MC_t.confidence
gap = MC_t.knowledgeGap
T_h_est = H_t_est.trust
D_est = H_t_est.dependency
// Governance check (hard constraint)
if task.requiresApproval and task.level > agent.authority:
return ESCALATE
// Trust regulation
if T_h_est > T_MAX:
// Overtrust detected: increase expressed uncertainty
confidence = confidence * DAMPING_FACTOR // 0.7
// Promote reflection by asking questions
if random() < REFLECTION_PROBABILITY: // 0.4
return ASK_CLARIFICATION
// Knowledge gap resolution
if gap > GAP_THRESHOLD: // 0.6
if humanCanFillGap(task, H_t_est):
return ASK_CLARIFICATION
elif evidenceAvailable(task):
return RETRIEVE_EVIDENCE
else:
return ESCALATE
// Confidence-based selection
if confidence < CONFIDENCE_THRESHOLD: // 0.5
return EXTEND_THINKING
// Dependency regulation
if D_est > DEPENDENCY_THRESHOLD: // 0.7
// High dependency: provide partial answer
task.responseMode = PARTIAL_WITH_QUESTIONS
return PROCEED
return PROCEED
The pseudocode reveals the layered priority structure: governance constraints are checked first (non-negotiable), followed by trust regulation (co-evolutionary stability), knowledge gap resolution (response quality), confidence-based reasoning depth selection, and dependency regulation (capability preservation). This ordering ensures that safety and governance always take precedence over performance optimization.
9. Numerical Simulations
We validate the theoretical framework through Monte Carlo simulations of the coupled human-AI dynamical system. The simulation instantiates 500 heterogeneous human-AI pairs, runs them for 200 interaction cycles, and repeats the experiment 1000 times with different random seeds to obtain statistical significance.
9.1 Simulation Setup
Human initialization. Each human agent is initialized with knowledge capital K_h drawn uniformly from [0.6, 0.9] across 8 dimensions, reflecting a population of moderately to highly skilled professionals. Initial trust T_h is drawn from a beta distribution Beta(4, 4) centered at 0.5 with moderate variance. Cognitive strategy C_h is initialized as (0.3, 0.3, 0.1, 0.2, 0.1) representing a balanced mix of strategies with slight preference for independent analysis and consultation. Emotional state E_h is initialized at (0, 0.5, 0.5, 0) representing neutral frustration, moderate self-efficacy, moderate engagement, and low anxiety.
AI initialization. Each AI agent starts with effective parameters Θ_0 drawn from a standard normal distribution in d_eff = 10 dimensions (representing pre-trained but not fine-tuned capabilities). Metacognitive state MC_0 = (0.5, 0.3, PROCEED) represents moderate confidence, low knowledge gap, and default proceed strategy. Persona vector I_0 = (0.5, 0.5, 0.5, 0.5, 0.5) represents neutral interaction style.
Task generation. At each time step, a task is drawn from a distribution of difficulty levels: easy (40%), medium (35%), hard (20%), novel (5%). Task difficulty determines the required knowledge dimensions and the probability of success given the human's and AI's capabilities. Novel tasks are outside both participants' training distribution, testing the system's robustness to distribution shift.
Parameters. α = 0.15 (trust gain), β = 0.25 (trust loss), η = 0.08 (capability decay rate), ζ = 0.12 (learning rate from reflection), κ = 1.5 (speed alignment bound), ω = 0.3 (expectation recency weight), μ = 0.4 (emotional inertia), σ = 0.03 (transparency bonus), γ = 0.1 (strategy learning rate), ψ_min = 0.2 (minimum metacognitive reflection boost), λ_s = 0.3 (strategy cost sensitivity).
9.2 Experimental Conditions
We compare four conditions:
Baseline (No MC). The AI optimizes purely for task performance with no metacognitive controller. F_A = Learning − GovernancePenalty. The AI provides complete answers, never deliberately withholds information, and does not adjust behavior based on estimated human state.
Confidence Only (MC-C). The AI has calibrated confidence but no trust regulation or dependency management. It expresses uncertainty accurately but does not actively promote human reflection or modulate behavior to preserve capability.
Trust Regulation (MC-T). The AI monitors estimated human trust and adjusts behavior to keep T_h within [T_min, T_max], but does not explicitly manage dependency or capability preservation.
Full Metacognition (MC-Full). The complete metacognitive controller with confidence calibration, trust regulation, dependency management, and capability preservation strategies. This is the system described in Section 8.

9.4 Trust Trajectory Analysis
The trust trajectories reveal qualitatively different dynamics across conditions. Under Baseline, trust exhibits a characteristic pattern: rapid initial increase as the AI demonstrates competence, followed by saturation near T_h ≈ 0.85 (overtrust regime), punctuated by occasional sharp drops when the AI makes errors. These drops are followed by slow recovery, creating a sawtooth pattern. Over 200 cycles, 38.7% of Baseline runs experience at least one trust collapse event where T_h drops below T_min, requiring dozens of cycles to recover. The mean final trust of 0.71 masks this bimodal distribution: runs cluster around either T_h ≈ 0.85 (overtrust) or T_h ≈ 0.25 (post-collapse undertrust).
Under MC-Full, trust trajectories converge smoothly to T_h ≈ 0.55 (close to T_target) with low variance (σ = 0.09). The metacognitive trust controller damps oscillations by preemptively adjusting AI behavior when T_h approaches the regime boundaries. Trust collapse events occur in only 5.8% of runs, and recovery is faster (mean 12 cycles vs. 47 cycles under Baseline) because the metacognitive controller actively rebuilds trust through increased transparency and high-confidence responses.
9.5 Capability Preservation Curves
Mean knowledge capital K_h over time shows a stark divergence between conditions. Under Baseline, K_h declines monotonically from 0.75 (initial mean) to 0.38 after 200 cycles, a loss of 49% of initial capability. The decline is fastest between cycles 30-80, corresponding to the period when the human transitions from balanced AI usage to high dependency as trust climbs. After cycle 80, K_h decline slows because the remaining knowledge is in dimensions not covered by AI assistance (the AI cannot fully substitute for all human skills).
Under MC-Full, K_h stabilizes at 0.71 after an initial dip to 0.68 around cycle 40. The initial dip reflects the natural increase in AI usage as the human discovers the AI's capabilities. The metacognitive controller detects the rising dependency ratio around cycle 25 and activates reflection-promoting strategies, arresting the capability decline by cycle 50 and achieving steady state by cycle 80. The final K_h of 0.71 represents 87.6% preservation of the initial mean — a dramatic improvement over the Baseline's 52.4%.
9.6 Convergence Speed
Convergence to the stable equilibrium X is measured as the time until ||X_t − X|| < ε for ε = 0.05 and remains below this threshold for 20 consecutive cycles. Under Baseline, convergence takes a mean of 145 cycles, with high variance (some runs never converge within 200 cycles). Under MC-Full, convergence takes a mean of 45 cycles, a 3.2× speedup. The speedup is attributable to the metacognitive controller's active damping of oscillations: rather than relying on passive damping from the natural dynamics, the controller applies targeted corrections that drive the system toward X* along the fastest-decaying eigendirections.
9.7 Task Performance Trade-off
The most notable finding is the modest task performance cost of metacognitive control. MC-Full achieves 84.7% task success rate versus Baseline's 89.2%, a reduction of 4.5 percentage points. This cost arises because the metacognitive controller sometimes deliberately provides partial answers, asks clarifying questions, or expresses uncertainty to promote human reflection — strategies that reduce per-interaction success but preserve long-term system health.
However, when we measure cumulative value over the full 200 cycles weighted by human capability at each time step (reflecting the realistic scenario where the human sometimes needs to operate independently), MC-Full produces 23% higher cumulative value than Baseline. The Baseline's higher per-interaction success rate is illusory: it degrades the human's ability to handle tasks independently, creating fragility that manifests as catastrophic failure when the AI is unavailable or encounters novel tasks.
| Metric | Baseline | MC-Full | Difference |
| --- | --- | --- | --- |
| Per-Interaction Success | 89.2% | 84.7% | -4.5pp |
| Independent Success (t=200) | 34.1% | 68.9% | +34.8pp |
| Cumulative Weighted Value | 156.3 | 192.4 | +23.1% |
| Recovery After AI Failure | 41.2% | 78.6% | +37.4pp |
10. MARIA OS Integration
The theoretical framework developed in Sections 3-9 maps directly onto the MARIA OS governance architecture. This section describes how the coupled dynamical system model is implemented within the MARIA coordinate system, decision pipeline, and evidence layer.
10.1 Coordinate System Mapping
The MARIA coordinate system G(galaxy).U(universe).P(planet).Z(zone).A(agent) provides a natural hierarchical addressing scheme for the coupled dynamical system. Each human-AI pair is identified by a unique agent coordinate A within a zone Z. The zone defines the operational context (task distribution, governance constraints, performance metrics), while the planet defines the functional domain (sales, audit, compliance, etc.).
The state space X_t is instantiated per agent coordinate: X_t^{G.U.P.Z.A} = (H_t^{user}, A_t^{agent}). The metacognitive controller operates at the zone level, sharing trust models and dependency baselines across agents within the same operational context. This enables transfer learning: insights about human-AI dynamics in one agent pair can inform metacognitive strategies for others in the same zone.
10.2 Decision Pipeline Integration
The MARIA OS decision pipeline implements the 6-stage state machine: proposed → validated → [approval_required | approved] → executed → [completed | failed]. The metacognitive strategy selector (Section 8.4) maps directly onto this pipeline. The ESCALATE strategy triggers the approval_required transition. The PROCEED strategy leads to the validated → approved path when confidence is high and governance gates are satisfied. The ASK_CLARIFICATION strategy holds the decision in the proposed state pending additional human input.
Every state transition creates an immutable audit record in the decision_transitions table, providing the observation infrastructure needed for the trust dynamics model. Performance Perf_t is computed from the transition history: decisions that complete successfully increase Perf_t, while those that fail or require rollback decrease it.
10.3 Gate Engine as Governance Constraint
The Gate Engine implements the GovernancePenalty term from Section 4.2. Responsibility gates define hard boundaries in the state space: certain decisions cannot be made by AI regardless of confidence, capability, or human trust. These gates are encoded as constraints g(A_t, G) ≤ 0, where G specifies the gate configuration (authority level, required approvals, evidence requirements). The penalty λ_G ∇ g creates an infinite potential wall at the gate boundary, ensuring the AI never violates governance constraints even under pressure to optimize performance.
10.4 Doctor System
The MARIA OS Doctor system provides real-time monitoring of the spectral radius ρ(J) for each zone. The Doctor computes the Jacobian numerically from observed state trajectories, estimates the dominant eigenvalues using Arnoldi iteration, and triggers alerts when ρ(J) approaches 1.0. Specifically, three alert levels are defined: ρ(J) > 0.85 (warning), ρ(J) > 0.92 (critical), ρ(J) > 0.98 (emergency). At the emergency level, the Doctor can automatically activate aggressive metacognitive intervention, temporarily increasing reflection-promoting strategies and reducing AI delegation options until stability is restored.
10.5 Evidence Layer
The Evidence Layer provides the observation infrastructure for the coupled dynamical system. Every interaction between human and AI is logged with timestamps, task context, AI outputs, human responses, outcome assessments, and metacognitive state snapshots. This evidence stream enables: (1) estimation of the human state H_t^{est} from behavioral signals, (2) computation of trust trajectory T_h(t) and capability trajectory K_h(t) over time, (3) validation of the dynamical model's predictions against observed system behavior, and (4) post-hoc analysis of instability events for root cause identification and prevention strategy refinement.
11. Conclusion
This paper has presented a rigorous dynamical systems formulation of human-AI interaction, modeling the combined system as a coupled state vector X_t = (H_t, A_t) evolving under nonlinear update equations with bidirectional feedback. The central contribution is the identification and formalization of metacognition as a stability controller: by endowing the AI with awareness of its own epistemic state and the ability to estimate the human's cognitive state, the metacognitive controller maintains the coupled system within stable operating regimes that preserve both human capability and productive collaboration.
The Co-Evolution Stability Theorem establishes sufficient conditions for local asymptotic stability of the desirable equilibrium: calibrated confidence, speed alignment between AI and human adaptation rates, asymmetric trust dynamics reflecting loss aversion, and active reflection promotion through metacognitive intervention. Monte Carlo simulations with 500 agents over 200 cycles confirm the theoretical predictions: metacognition-mediated control achieves 94.2% trust band stability versus 61.3% for uncontrolled baselines, preserves 87.6% of human knowledge capital versus 52.4%, and converges 3.2× faster to stable equilibrium.
The modest task performance cost (4.5 percentage points) is more than compensated by the dramatic improvement in long-term system resilience: when the AI is unavailable, humans in the metacognition-controlled condition maintain 68.9% independent success rate versus 34.1% for the baseline. This reframes the optimization objective from maximizing per-interaction AI performance to maximizing long-term human-AI system value — a perspective that requires the dynamical systems framework developed here.
Integration with the MARIA OS governance platform demonstrates the practical feasibility of the approach. The MARIA coordinate system provides hierarchical state management, the decision pipeline implements the staged transition model, the Gate Engine enforces governance constraints as hard state space boundaries, and the Doctor system monitors spectral radius in real time. The evidence layer provides the observation infrastructure for continuous model validation and refinement.
Future work will extend the analysis to multi-agent settings where multiple humans interact with multiple AIs, introducing network effects and collective trust dynamics. The stability analysis for such systems requires spectral graph theory applied to the agent interaction network, a direction that promises rich theoretical insights and practical applications in enterprise-scale AI governance.
