Catastrophic forgetting is not an engineering failure. It is a mathematical consequence of storing knowledge as global parameter superposition. Existing methods, such as regularization, replay, and frozen subnetworks, add external mechanisms to a shared-parameter substrate. None derives retention from the learning dynamics themselves. This paper introduces the Informational Buildup Framework (IBF), an alternative substrate for continual learning, based on the premise that information is the achievement of structural alignment rather than stored content. In IBF, two equations govern the dynamics: a Law of Motion that drives configuration toward higher coherence, and Modification Dynamics that persistently deform the coherence landscape in response to localized discrepancies. Memory, agency, and self-correction arise from these dynamics rather than being added as separate modules. We first demonstrate the full lifecycle in a transparent two-dimensional toy model, then validate across three domains: a controlled non-stationary world, chess evaluated independently by Stockfish, and Split-CIFAR-100 with a frozen ViT encoder. Across all three, IBF achieves replay-superior retention without storing raw data. We observe near-zero forgetting on CIFAR-100 (BT = -0.004), positive backward transfer in chess (+38.5 cp), and 43% less forgetting than replay in the controlled domain. In chess, the framework achieves a mean behavioral advantage of +88.9 +/- 2.8 cp under independent evaluation, exceeding MLP and replay baselines.

Table 1: RRW results (5 seeds, mean ± std). Full IBF achieves substantially stronger backward transfer and forward learning than the compared MLP baselines. The ablations do not function here as weaker versions of the full system, but as controlled probes of distinct mechanisms inside an explicitly contradictory domain.

Primitive
Symbol
Definition
Field
F
A nonempty universal set whose elements are informational patterns; the total space of possible informational configurations.
Pattern
ψ∈F
An element of the Field. Patterns possess no intrinsic meaning or stability independent of their relations to systems and scales.
Closed Informational System (CIS)
S⊂F
A connected region of configuration space where coherence exceeds a viability threshold and boundary gradients point inward, actively resisting dissolution.
Observational Scale
λ∈Λ
A resolution parameter specifying the level of abstraction at which patterns and systems are distinguished. Determines which distinctions are operational and which coherence function applies.
Configuration Space
C(S,λ)
For each system S at scale λ , the differentiable manifold of all admissible internal states. Every point represents a possible internal configuration.
Coherence
R(xS,S,λ)
A scalar function quantifying the degree of structural alignment between a system’s internal configuration and its environment. Relational, fragile, non-reducible.

Closure Postulates
Table 5: Formal Structure and Placement in the Broader Arc. The four axioms and the local modification postulate stated in this paper define the minimal structure needed to ground the continual learning experimental program. The table also situates that local arc within the broader foundational framework, whose remaining closure postulates and claims are shown here in condensed form. Rows marked Here are stated or empirically instantiated in this paper; rows marked Foundational belong to the larger dedicated treatment. Claims 9 and 10 are operationalized jointly in this paper as the Self-Correction capacity: the system reflexively tracks its cross-context coherence state (Thm. 9) to selectively trigger the thermodynamic dissolution of false alignment (Thm. 10).
