A Normative–Computational Architecture for Interpreting and Acting Under Uncertainty
Physics Programme
Status: Physics-Facing Representational Programme
This page outlines a research agenda concerning state representation in predictive physical models.
It does not propose new physical laws, but examines whether standard state descriptions are adequate in regimes where contextual structure influences observable outcomes.
Any extension to established physics must satisfy derivation, limit recovery, and empirical discriminability. Its epistemic governance guidance note is available here alongside the admissibility protocol.
Because many frameworks discussed throughout this programme employ overlapping terminology while preserving distinct operational structures, a separate Minimal Operational Lexicon and Glossary have been developed alongside the present architecture. The lexicon is not intended to impose universal definitions across frameworks, but rather to preserve contextual admissibility during comparison, translation, and interoperability analysis between partially overlapping representational systems. Its core philosophy and logic premise are available for separate review. Its relation to the overall project’s minimal schema reads as follows:

A Physics-Facing Research Programme in Contextual Admissibility and Operational Modelling
Stefaan Vossen
Dot Theory Research Programme
Purpose
This page outlines as entry point to the overall Programme, the Physics-facing research programme associated with Dot theory, a cross-domain modelling hypothesis about representational completeness, proposing that explicitly modelling contextual variables may improve prediction in systems where standard state representations are insufficient.
Dot theory is not a theory in the classical physical sense but a contextual admissibility framework for evaluating, constructing, comparing, and combining partially overlapping representational systems under conditions of incomplete informational accessibility, projection-sensitive reduction, and constrained recoverability.
Dot theory is not presented as a completed physical theory. Instead, it proposes a modelling question concerning state representation and prediction in complex dynamical systems.
The Dot theory Physics-facing Programme began as an attempt to address persistent instabilities in context-independent physical modelling, observer separation, informational accessibility, and projection-sensitive reduction. As the framework developed, it became increasingly clear that these difficulties reflected a deeper epistemic-operational problem concerning the conditions under which operational procedures themselves become admissible. This led to the development of the Contextual Admissibility Research Programme, which generalises the underlying epistemic architecture from which the physics-facing structures emerged and resulted in a Sheaf-Theoretic Formalisation of Contextual Admissibility and Locally Generated Operational Procedures. Their shared lexicon can be found here: https://www.dottheory.co.uk/paper/lexicon
This Physics-facing programme therefore now functions as one operational domain within a broader admissibility framework governing contextual informational accessibility, local procedural generation, and constrained recoverability. The proposed mathematical formalisation develops these structures using existing and validated contextual mathematical tools including sheaf-like operational geometry and admissibility-constrained topology.
The Dot Theory Programme investigates and formalises the relationship between informational accessibility, observer embedding, operational reduction, and physical modelling under conditions of constrained recoverability. The programme originated as a physics-facing investigation, but progressively evolves into a broader epistemic-operational framework governing contextual admissibility and locally generated operational procedures (links):

Empirical Operational Applications
This programme investigates whether predictive models become limited when contextual information influencing system dynamics is excluded from the state representation used in computation. A minimal implementation of this benchmark is available as a public repository:
https://github.com/stefaanvossen/dot-theory
The central aim is therefore modest but novel and precise and situated within the Dot theoretical framework, also known as Generative Interpretive Architecture (GIA):
to determine whether extending a model’s state representation to include contextual structure improves predictive accuracy in regimes where such structure influences observable outcomes.
The programme proceeds through computational benchmarks, modelling experiments and formal analysis rather than through immediate modification of established physical theory. For terms and boundaries please: https://www.dottheory.co.uk/paper/on-boundaries
Representational Hypothesis
Many physical and computational models operate on a defined state space.
Let
ψ ∈ ℋ
represent a conventional state description.
Dot Theory proposes examining an augmented representation
Ψ = (ψ, μ) ∈ ℋ × ℳ
where μ represents contextual variables associated with the system’s regime, measurement conditions or environmental structure as described within the proposed framework, the Contextual Admissibility Research Programme, and the mathematical formalisation.
The projection
π(Ψ) = ψ
recovers the conventional model.
The research question becomes:
Under what circumstances does the projection π discard information required to predict observable outcomes?
Clarification: modelling convenience vs necessity
In many modelling frameworks, contextual variables can be incorporated into an enlarged state space. The present programme does not dispute this.
The question addressed here is whether omitting such variables in practice is merely a matter of convenience or whether it introduces systematic limitations in prediction and control.
Where omission leads to indistinguishable states with different observable outcomes, the distinction becomes one of necessity rather than convenience.
If two augmented states:
Ψ₁ ≠ Ψ₂
project to the same ψ but produce different observable distributions, then modelling exclusively in ℋ may be representationally incomplete in that regime.
This hypothesis is domain-specific and must be tested empirically.
Relation to Existing Physics
This programme does not claim that established physical theories are incorrect.
Quantum Mechanics, Quantum Field Theory and General Relativity remain extraordinarily successful as independent predictive frameworks. Instead, Dot Theory is a research programme proposing that many models (in physics, healthcare, and systems) are incomplete because they may ignore contextual information and that explicitly modelling that context can improve prediction. It specifies meaning more specifically as here: https://www.dottheory.co.uk/paper/on-boundaries
Any representational extension must therefore satisfy strict conditions:
1. Limit Recovery
When contextual variables μ are irrelevant or averaged out, the augmented model must reduce to the standard formulation.
2. Symmetry Preservation
Extensions must preserve or explicitly justify any modification to established symmetries, such as:
Lorentz invariance
gauge invariance
unitarity
3. Mathematical Coherence
The extended state space ℋ × ℳ must support well-defined dynamics and observables.
4. Empirical Discriminability
The extension must produce at least one measurable difference relative to the reduced model within a defined regime.
Without these conditions, the programme has no standing as mathematical physics.
Reproducible Test
Representational Incompleteness in a Regime-Switching Dynamical System.
To make the representational hypothesis testable, a minimal computational benchmark is used.
The benchmark models a dynamical system whose behaviour depends on an unobserved regime variable.
The system alternates between two regimes, producing different dynamics.
If a predictive model observes only the system state ψ, it cannot always distinguish between regimes when they produce identical instantaneous observations.
However, if a contextual variable μ representing the regime is included, predictive accuracy may improve.
The benchmark, therefore, tests whether augmenting the state representation improves prediction when regime switching occurs. An experimental approach is offered here: https://www.dottheory.co.uk/paper/context-sensitive-modelling-in-practice
Consider a discrete-time dynamical system.
Hidden system state:
sₜ
Observed variable:
oₜ = sₜ + noise
Regime variable:
μₜ ∈ {0,1}
The regime determines the system’s evolution.
Example dynamics:
If μₜ = 0
sₜ₊₁ = 0.9 sₜ + ε
If μₜ = 1
sₜ₊₁ = −0.5 sₜ + ε
where ε represents small stochastic noise.
The observation alone does not always uniquely determine the governing regime.
Competing Predictive Models
Two predictive models are evaluated:
A. Baseline Model
The baseline predictor receives only the observation
Input
oₜ
Prediction
ŝₜ₊₁ = f(oₜ)
This corresponds to modelling with state ψ alone.
B. Augmented Model
The augmented predictor receives both observation and contextual information
Input
(oₜ, μₜ)
Prediction
ŝₜ₊₁ = f(oₜ, μₜ)
This corresponds to modelling with the extended state
Ψ = (ψ, μ).
Evaluation
Prediction accuracy is measured across the full simulation.
A typical metric is mean squared prediction error.
If contextual variables influence system dynamics, the augmented model should achieve lower error.
If contextual variables are irrelevant, both models should perform similarly.
Implementation
A minimal implementation of this benchmark is available as a public repository:
https://github.com/stefaanvossen/dot-theory
The repository contains a compact Python script that
generates regime-switching data
trains baseline and augmented predictors
evaluates prediction error
visualises the results.
The experiment can be executed with a single command:
python dot_benchmark.py
Expected Output
The benchmark produces a simple plot comparing prediction error over time.

Vertical axis
prediction error
Two curves are shown
baseline model error
augmented model error
When regime switching occurs, the baseline model error increases because the model cannot distinguish between governing dynamics.
The augmented model tracks the system more accurately because regime information is available.
Scope
This benchmark is intentionally minimal. In order for this programme to be a scientific programme, it must fulfil certain criteria and this page being here is one such.
It does not claim to modify existing physical theory.
Instead, it demonstrates an epistemically non-trivial modelling principle:
Predictive performance may depend on whether the state representation used by a model captures the contextual structure governing system dynamics.
If the representational hypothesis proves useful in simple computational systems, future work may explore more structured domains, including
experimental measurement modelling
simulation environments
complex dynamical systems.
Programme Outlook
The long-term aim of this research programme is to examine how state representation influences predictive modelling across physical and computational systems.
The work proceeds incrementally through:
minimal computational benchmarks
formal modelling frameworks
empirical evaluation in increasingly structured domains.
The present benchmark serves only as a first test of the representational hypothesis and is merely an expression of this website’s greater Philosophy of Science project.
Closing Remark
This programme proposes a modest but testable question and therefore appears central. The website and project as a whole however present other material required to make this work a scientific programme in the logic of the philosophy of natural science. While this is a complex and novel object for scientific consideration, its unusual composition only reflect the (Kuhnian) paradigmatic shift contained within it.
If modelling performance depends on the completeness of the state representation used to describe a system, then identifying regimes of representational incompleteness may be a useful tool for studying complex dynamical systems. This programme embodies that proposition and allows expansion into its sub-programme, Glossary, Lexicon and admissibility protocol. For mathematical proposals, philosophical and ethical considerations or experimental implementation please follow the highlighted links.
The benchmark provided is intended simply as a transparent starting point for investigating that possibility across a disciplined and collaborative scientific endeavour.
Thank you for your time, attention and consideration,
