Coherence Trifecta Control Loop

Mechanism

The cognitive layer maintains coherence between the agent's stated commitments and its current reasoning state. The mechanism evaluates each new commitment against the agent's prior commitments, its policy reference, and its outstanding obligations. A cognitive deviation is recorded when a new commitment contradicts a prior commitment without an explicit revision step, when reasoning produces a conclusion outside the policy-permitted action space, or when the agent's stated rationale fails to chain to its declared values.

The behavioral layer maintains coherence between the agent's commitments and its observed actions. Every action emitted by the agent is reconciled against the commitment that authorized it. A behavioral deviation is recorded when an action lacks an authorizing commitment, when an action exceeds the scope of its authorizing commitment, or when the action's measurable effects diverge from the commitment's stated intent beyond a tolerance defined by policy.

The biological layer — termed biological by analogy to the substrate-and-energetics layer of an embodied agent, and applicable equally to computational substrate metrics — maintains coherence between the agent's operating state and the substrate it requires. A biological deviation is recorded when substrate telemetry indicates that the agent is operating outside the envelope in which its cognitive and behavioral guarantees hold: thermal limits exceeded, memory floor breached, scheduler starvation detected, sensor calibration drifted beyond bounds, or attestation channels degraded.

The trifecta loop processes each deviation event in three phases. Phase one classifies the deviation against the three layers, producing a deviation signature that may be cognitive-only, behavioral-only, biological-only, or any combination thereof. Phase two evaluates collapse: a layer is judged collapsed when the deviation rate within that layer over a policy-defined window exceeds the collapse threshold, or when a single deviation of policy-defined severity is observed. Phase three issues the structural response, which depends on the collapse pattern.

Single-layer collapse triggers layer-specific remediation. Cognitive collapse triggers a commitment-revision cycle in which contradictions are surfaced for explicit reconciliation. Behavioral collapse triggers an action-suspension cycle in which outstanding actions are reviewed against their authorizing commitments. Biological collapse triggers a substrate-stabilization cycle in which the agent contracts to a minimal-substrate operating mode. Multi-layer collapse triggers escalation: the agent transfers authority to an external supervisor, because joint collapse indicates that the agent's self-correction primitives are themselves compromised.

Operating Parameters

The collapse threshold is a triple (theta_c, theta_b, theta_g) corresponding to cognitive, behavioral, and biological deviation rates. Each component is a frequency over a windowed interval, with defaults set by domain policy. The severity threshold is a per-layer scalar that triggers collapse on a single high-severity deviation regardless of rate. The window length W governs the rolling interval over which deviation rates are computed.

The remediation parameters are layer-specific. The commitment-revision cycle has a maximum duration and a maximum number of contradictions it may attempt to reconcile before escalating. The action-suspension cycle has a maximum number of in-flight actions it may hold and a timeout beyond which suspended actions are positively cancelled rather than indefinitely held. The substrate-stabilization cycle has a defined minimal-substrate operating mode and a timeout for return to nominal substrate.

The multi-layer escalation rule is parameterized by the joint-collapse pattern. Two-layer joint collapse triggers escalation to a peer-class supervisor; three-layer joint collapse triggers immediate escalation to an out-of-band supervisor and a freeze of the agent's external action capacity until external clearance is granted. All parameters are policy-versioned and lineage-bound, ensuring retrospective audit can reconstruct exactly which thresholds governed any episode.

Alternative Embodiments

In a layered-precedence embodiment, the three layers are evaluated in strict sequence with short-circuit evaluation: a cognitive collapse halts further evaluation in the same cycle and the behavioral and biological layers are not consulted until cognitive coherence is restored. This embodiment is preferred where layer interactions produce noisy signals and where serial evaluation gives cleaner remediation traces.

In a parallel-evaluation embodiment, all three layers are evaluated concurrently and the loop selects the most severe collapse for the structural response. This embodiment is preferred where deviation events are sparse and where parallel evaluation reduces loop latency. The embodiment includes a reconciliation step to ensure that simultaneous remediations do not conflict.

In a graded-collapse embodiment, each layer reports a continuous coherence score rather than a binary collapse signal. The loop's structural response is graded against the score, with low scores triggering preventive remediation before formal collapse. This embodiment is preferred where the cost of full remediation is high and where preventive intervention preserves capacity.

In a federated embodiment, the trifecta layers are evaluated by distinct subsystems with distinct trust roots. The cognitive layer is evaluated by the agent's own reasoning subsystem, the behavioral layer by an independent action-monitor with its own attestation chain, and the biological layer by substrate-attached telemetry with hardware roots. The federation ensures that no single subsystem can mask its own collapse, and is preferred for high-assurance deployments where defense-in-depth is required.

Composition With Other Primitives

The trifecta loop composes with the integrity envelope by treating layer-collapse events as negative-reconciliation evidence and successful remediation episodes as positive-reconciliation evidence. The asymmetric weighting of the envelope ensures that collapses contract the envelope immediately while remediation contributes to recovery only over time, encoding the structural truth that integrity is more easily lost than rebuilt.

The loop composes with the coping intercept primitive: rising deviation rates in any layer feed the pressure vector consumed by the intercept mechanism, allowing intercept to activate before formal collapse occurs. Conversely, an active intercept biases the collapse thresholds toward greater conservatism, recognizing that an agent already under bounded coping has less headroom to absorb additional deviation.

Composition with confidence governance is bidirectional. Per-layer coherence scores modulate the agent's confidence calibration, and confidence calibration outcomes feed back as cognitive-layer deviations when calibration error exceeds policy bounds. Composition with discovery traversal restricts exploration during any active collapse remediation; the exploration budget is held until full trifecta coherence is restored.

Distinction From Prior Art

Multi-modal monitoring frameworks aggregate signals from independent subsystems into a unified health score, sharing the federated-evaluation premise but not the per-layer collapse criteria, the layer-specific remediation cycles, or the multi-layer escalation rule. Such frameworks produce a scalar score and an alert; they do not specify a structural response that distinguishes single-layer remediation from multi-layer escalation. The mechanism specified here defines the response topology, not merely the detection topology.

Behavioral verification systems compare emitted actions against intended actions, sharing the behavioral-layer premise but not the integration with cognitive commitment-revision or substrate stabilization. Behavioral verification alone cannot detect the case in which actions match commitments but the commitments themselves contradict prior commitments — a cognitive collapse invisible to behavioral monitoring.

Substrate-monitoring frameworks track hardware health and trigger failover when limits are breached, sharing the biological-layer premise but operating in isolation from the agent's commitment and action layers. Substrate monitoring alone cannot detect the case in which the substrate is nominal but the agent's reasoning has decohered, and cannot prevent the agent from emitting incoherent actions on healthy substrate. The trifecta mechanism integrates the three layers into a single primitive with a unified response topology, distinct from the union of independent monitors.

Governance and Audit Implications

The trifecta loop's most consequential governance property is the multi-layer escalation rule. Single-layer collapse is a familiar failure pattern that any well-designed monitoring system can detect and remediate. Multi-layer joint collapse is qualitatively different: when two or more layers fail simultaneously, the agent's self-correction primitives are themselves implicated, because the layers were architected to provide independent checks. Joint collapse therefore cannot be remediated by the agent's own remediation cycles; it must be remediated by an external supervisor whose authority and competence are unaffected by the failure that compromised the agent. The structural enforcement of escalation under joint collapse encodes the principle that an agent cannot be both judge and defendant in proceedings concerning its own coherence.

The federated embodiment merits particular attention from a governance perspective. By assigning each layer to a subsystem with its own trust root, the federation ensures that no single subsystem can mask a deviation it has introduced. A reasoning subsystem cannot conceal a cognitive deviation it has produced because the behavioral and biological subsystems will independently observe the consequences. An action-monitor cannot conceal a behavioral deviation because cognitive and biological signals will register the discrepancy. Substrate telemetry cannot conceal a biological deviation because cognitive and behavioral subsystems will eventually surface the divergence. The federation transforms the trifecta from a self-monitoring primitive into a mutually-attesting primitive, which is the appropriate posture for high-assurance deployments.

The lineage binding between collapse events and integrity reconciliation produces a closed loop between local detection and global accounting. Every collapse event reconciles negatively against the integrity envelope, and every successfully closed remediation cycle reconciles positively. Over time, the envelope's trajectory therefore reflects not merely the agent's nominal performance but its capacity to detect and recover from its own incoherence. An agent that experiences few collapses but recovers cleanly when they occur develops a distinct envelope trajectory from an agent that experiences few collapses because its detection thresholds are set permissively, and the audit record permits external parties to distinguish the two cases.

Disclosure Scope

This disclosure encompasses the three coherence layers (cognitive, behavioral, biological), the per-layer deviation classification, the per-layer collapse criteria expressed as windowed-rate thresholds and per-event severity thresholds, the three layer-specific remediation cycles (commitment revision, action suspension, substrate stabilization), the multi-layer joint-collapse escalation rule, and the lineage binding between collapse events and integrity reconciliation. The disclosure encompasses the primitive's composition with the integrity envelope, coping intercept, confidence governance, and discovery traversal, and the four enumerated alternative embodiments. The disclosure is independent of substrate, host application, and reasoning implementation; the structural relationships between per-layer evaluation, layer-specific remediation, and multi-layer escalation define the protected subject matter.
