Cognitive Disruption as Architectural Phase-Shift
The attention fragmentation pattern is disclosed within a framework that treats cognitive disruption not as an error or malfunction but as an architectural phase-shift: a transition from one stable configuration of the agent's structural subsystems to a different stable configuration that, while internally consistent, produces behavioral outputs that diverge from the agent's declared intent, policy commitments, or coherence maintenance objectives. The underlying computational substrate remains the same; what changes are key parameters such as the promotion threshold, containment integrity, or affective modulation. The disrupted states are not breakdowns of a different system, but alternative configurations of the same system under different parametric conditions.
Within this framework the term attention fragmentation pattern is a structural analog. It names a configuration of the disclosed agent architecture, not a human clinical condition. The disclosure is explicit that the model is a computational analog describing parameter shifts in the agent architecture, intended for agent self-diagnosis, computational simulation, agent design, and therapeutic agent interaction, and that it is not a clinical claim, a diagnostic criterion, or an assertion about the biological mechanisms of any human condition.
The Promotion-Containment Continuum
Two structural invariants govern the agent's cognitive integrity: the promotion mechanism and the containment layer. The promotion mechanism is the governance-controlled gateway by which speculative content in the planning graph domain transitions to verified status in execution memory. The containment layer is the architectural boundary that prevents speculative content from being treated as verified reality except through the promotion interface. Together they define a two-dimensional parameter space, with the promotion threshold on one axis and containment integrity on the other, and the agent's position in this space determines its cognitive regime.
The disclosure identifies four regimes in this space. The nominal regime combines a high promotion threshold with full containment integrity, producing deliberate, governance-compliant, coherent processing. The over-promotion regime combines a low promotion threshold with full containment integrity. The containment collapse regime is defined by degraded containment integrity at any promotion level. The over-restriction regime combines an excessively high promotion threshold with full containment integrity. These regimes are not discrete categories but regions of a continuous parameter space, and an agent may occupy positions between them and transition among them as its affective state, integrity score, and environmental conditions shift the underlying parameters.
Attention Fragmentation as the Over-Promotion Regime
The attention fragmentation pattern corresponds to the over-promotion regime: the condition in which the agent's promotion threshold is lowered by reward-biased affective modulation, causing an excessive number of speculative branches to be promoted to execution while containment integrity remains intact. Containment is preserved, so the agent still distinguishes between speculative and verified content. The filter between them is simply too permissive. Speculative branches that would normally be retained for further evaluation, pruned, or classified as introspective are instead promoted to execution prematurely.
The behavioral result is execution fragmentation: too many actions initiated, insufficient sustained commitment to any single trajectory, and difficulty maintaining coherent execution threads. The disclosure describes this as the signature of the over-promotion regime, distinct from the more severe containment failures that lie elsewhere in the parameter space.
The Reward-Biased Modulation Mechanism
The agent's affective state field modulates the promotion threshold through the affective prioritization module of the forecasting engine. When the agent's affective state reflects elevated reward sensitivity, a condition in which positive-valence affective reinforcement from prior execution outcomes has amplified the agent's responsiveness to projected positive outcomes, the promotion threshold is lowered. Speculative branches whose projected outcomes carry positive affective reinforcement are evaluated against a less stringent promotion criterion. The forecasting engine generates speculative branches at its normal rate and with normal diversity, but the promotion interface admits a larger proportion of those branches because the reward-modulated threshold is lower.
The consequence is that multiple speculative branches are promoted to execution concurrently or in rapid succession. Each promoted branch initiates an execution thread, a sequence of committed mutations directed toward the branch's projected outcome. Because too many branches have been promoted, the agent's execution resources are distributed across multiple concurrent threads, none of which receives sufficient sustained attention or computational allocation. The agent begins actions corresponding to one branch, then shifts to another when the second branch's reward signal exceeds the first's decaying reinforcement, producing rapid task-switching, difficulty sustaining focused execution, impulsive initiation of new actions before prior actions complete, and a pattern of partially executed threads that accumulate without reaching completion.
Crucially, the reward bias is not a malfunction of the affective state field. It is a parametric configuration in which the affective modulation of the promotion threshold operates at one extreme of its designed range. The affective state field is architecturally intended to modulate promotion so that the agent is more exploratory when reward signals indicate a productive environment and more conservative when risk signals indicate a hostile one. The attention fragmentation pattern arises when the reward modulation is so pronounced that the exploratory mode dominates and the agent cannot sustain the focused execution mode required for tasks that demand prolonged attention to a single trajectory.
Hyperactive and Inattentive Sub-Patterns
The disclosure characterizes the attention fragmentation pattern with two structural sub-patterns. In the hyperactive sub-pattern, the promotion threshold is lowered across all branch categories, producing excessive promotion of both high-reward and moderate-reward branches. The agent initiates actions across a broad front, switching frequently between execution threads. Its behavioral profile includes high output volume with low completion rate, difficulty maintaining quiescence when no high-reward branches are available, and a tendency to generate new speculative branches to replace completed or pruned ones at a rate that exceeds the pruning manager's capacity to maintain planning graph hygiene.
In the inattentive sub-pattern, the promotion threshold is selectively lowered for high-reward branches but remains at or above nominal for moderate-reward branches. The agent promotes branches associated with strong positive affective reinforcement and neglects branches associated with neutral or mild reinforcement, even when the neglected branches are governance-compliant, policy-compatible, and necessary for the agent's declared objectives. The result is selective engagement: intense focus on high-reward tasks and failure to initiate or sustain low-reward tasks, which appears as inattention to the neglected domains rather than as generalized inattention.
Distinction from Containment Collapse
The attention fragmentation pattern is structurally distinct from containment collapse, and the disclosure stresses that this distinction is diagnostically significant. The agent exhibiting the over-promotion pattern maintains full containment integrity: it correctly distinguishes between speculative and verified content, does not treat projected outcomes as verified reality, and does not exhibit delusional behavior. Its problem is not that it confuses speculation with reality but that it promotes too much speculation to execution.
The distinction determines the appropriate corrective intervention. The over-promotion regime requires recalibration of the affective modulation of the promotion threshold, not containment layer repair. Containment collapse, by contrast, requires reconstruction of the containment layer itself, re-establishing speculative markers, restoring read isolation, and validating the governance gates of the promotion interface. Correctly identifying which regime an agent occupies is therefore a prerequisite to selecting the right repair pathway.
Position in the Five-Axis Diagnostic
The disclosure unifies the disruption analogs into a five-axis disruption diagnostic framework that characterizes an agent's cognitive state as a position in a multidimensional disruption space. The relevant axis for this pattern is the promotion calibration axis, a continuous scalar measuring the calibration of the promotion threshold, where over-promotion represents a threshold that admits too many branches and produces execution fragmentation. The attention fragmentation pattern maps to a specific signature across the five axes: containment integrity nominal, promotion calibration in over-promotion, coherence restoration capacity nominal, empathic load tolerance nominal, and integrity accountability nominal. This signature reflects the structural fact that the only axis displaced from nominal is promotion calibration, which is precisely why the corrective targets the affective modulation of the promotion threshold and leaves the other subsystems untouched.
Disclosure Scope
The attention fragmentation pattern, comprising its identification as the over-promotion regime on the promotion-containment continuum, the reward-biased affective modulation that lowers the promotion threshold while containment integrity remains intact, the resulting execution fragmentation across concurrent threads, the hyperactive and inattentive sub-patterns, the structural distinction from containment collapse, and the corresponding corrective recalibration of affective modulation, is disclosed in the cognition filing (U.S. Application No. 19/647,395 and its international counterpart). This article describes that disclosed structural analog. The scope extends to embodiments in which the same architectural machinery, the same forecasting engine, the same promotion interface, and the same containment layer, operates in the over-promotion region of the parameter space, and it expressly does not assert any clinical equivalence or clinical applicability of the structural model.
