Step 2 — Geometry‑Aligned Representation
Adaptive Logic constructs internal geometric structures that mirror the relationships within the system rather than imposing human‑defined abstractions. Step 2 formalises how those geometric structures are built, updated, and maintained inside the state space defined in Step 1.

Geometry–Aligned Representation Function — Plain Explanation
This describes a step where the system takes its current raw information and reorganizes it into a clearer, more structured internal format.
The goal is simply to turn messy input into something the system can reason about more easily.
- Everyday meaning: It means the system starts with whatever state it’s in — all the scattered details, readings, or signals — and reshapes them into a clean internal layout. Once the information is arranged in this structured “geometric” form, the system can spot patterns, compare things, and make decisions more effectively.
- Breakdown:
- Raw system state: All the unorganized information the system currently has — sensor readings, variables, or other inputs.
- Representation function: The step that tidies, organizes, and reshapes that raw information into a more meaningful structure.
- Internal geometric space: The organized format the system uses to understand relationships, positions, or patterns.
- Resulting representation: The cleaned‑up version of the system’s state, ready for reasoning, prediction, or further processing.
- In simple terms: It’s like taking a messy pile of notes and rewriting them into a clear diagram so the system can actually make sense of what’s going on.
that transforms the raw system state S into an internal geometric space Gint whose structure emerges from relationships within the system itself. This representation must preserve high‑dimensional relationships, multi‑scale interactions, and cross‑domain couplings without collapsing them into conceptual categories.
Outcome: A dynamic geometric representation Gint that evolves as the system evolves, serving as the foundation for Adaptive Inference.
2. Relationship first construction
Identify relationships: Instead of beginning with predefined variables, construct the representation by analysing relationships among variables, entities, and domains. Formally, compute a relationship tensor

Relationship Tensor — Plain Explanation
This expresses how two entities relate to each other based on their current conditions.
The system looks at both entities, compares their states, and produces a value that reflects how strongly they are connected.
- Everyday meaning: It means the system takes two things — people, objects, nodes, signals, anything — and figures out how similar they are, how much they affect each other, or how closely they are linked. The result is a simple description of their relationship at that moment.
- Breakdown:
- Entity states: The current information describing each entity — what it’s doing, what condition it’s in, or what features it has.
- Relationship operator: The rule or procedure the system uses to compare the two entities and decide how they relate.
- Relationship value: The final output that summarizes the connection — whether they behave similarly, depend on each other, or influence one another.
- Pairwise evaluation: The system repeats this comparison for every pair of entities, building a full picture of how everything is interconnected.
- In simple terms: It’s like asking, “How much do these two things go together?” and writing down the answer for every pair.

- Representation map into geometric space: \[ R : S \rightarrow G_{\text{int}} \] — converts raw system states into internal geometric representations used for distance computation.
Geometric Distance — Plain Explanation
This expresses how the system turns the strength of a relationship between two entities into a simple notion of “how far apart” they are inside its internal space.
Stronger relationships become shorter distances; weaker relationships become longer distances.
- Everyday meaning: It means the system looks at how closely two entities are connected — how similar they are, how much they interact, or how strongly they influence each other — and then converts that connection into a distance. If two entities are very alike or tightly linked, the system places them close together. If they barely relate, it places them far apart.
- Breakdown:
- Relationship value: A measure of how strongly two entities relate — whether they behave similarly, depend on each other, or share important features.
- Distance function: The rule that turns that relationship strength into a distance. Strong relationship → small distance. Weak relationship → large distance.
- Geometric distance: The final “how far apart are they?” number the system uses to arrange entities inside its internal space.
- Spatial interpretation: Once distances are computed for all pairs, the system can build a map‑like layout showing clusters, gaps, and structural patterns.
- In simple terms: It’s like saying: “If these two things go together, put them close; if they don’t, push them apart.”
angles, neighbourhoods, and local manifolds.
Set relationship boundaries: Ensure that relationships across domains (e.g., climate → economy) are included even when no conceptual category exists.
Example: CO₂ concentration, agricultural yield, and sovereign bond spreads may form a geometric neighbourhood even though they belong to different conceptual domains.

- Entity‑level state matrix: \[ X(t) \in \mathbb{R}^{q \times n} \] — structured input supplying all entity states for embedding.
State Embedding — Plain Explanation
This describes how the system takes an entity’s current condition, along with information about how it relates to others, and turns that into a compact internal representation.
The result is a structured “position” for the entity inside the system’s geometric space.
- Everyday meaning: It means the system looks at what an entity is doing right now and how it connects to everything around it. Using both pieces of information, it creates a clean, organized internal snapshot of that entity — something the system can easily compare, cluster, or reason about over time.
- Breakdown:
- Entity’s current state: All the details describing what the entity is like at this moment — its features, conditions, or signals.
- Relationship structure: Information about how the entity interacts with others — who it is similar to, influenced by, or connected with.
- Embedding function: The learned procedure that combines the entity’s state and its relationships into a single, well‑organized internal representation.
- Geometric embedding: The final structured “location” of the entity inside the system’s internal space, capturing both what it is and how it relates to others.
- In simple terms: It’s like taking a person’s profile and their social connections and turning them into a single, clear point on a map that shows how everyone fits together.

Domain Manifold — Plain Explanation
This expresses the idea of gathering all the internal representations that belong to a particular group or category and treating them as a single, shared space.
It’s simply the collection of all entities that fall under the same domain.
- Everyday meaning: It means the system takes every entity that belongs to a certain domain — a region, a sector, a category, a type — and puts their internal representations together. This collection forms the “shape” or structure of that domain inside the system’s geometric space.
- Breakdown:
- Domain membership: A simple rule that says which entities belong to the domain — like “all cities in region A” or “all companies in sector B.”
- Entity embeddings: The internal representations the system has already created for each entity, capturing its features and relationships.
- Domain manifold: The full set of those embeddings, grouped together because they belong to the same domain. This set forms the domain’s internal geometric structure.
- Shared space: Once collected, the system can analyze the domain as a whole — seeing clusters, boundaries, trends, or patterns within that group.
- In simple terms: It’s like gathering all the points on a map that belong to one region and saying, “This whole cluster is the shape of that region.”

Latent Geometry Mapping — Plain Explanation
This describes a step where the system takes an entity’s already‑organized internal representation and transforms it again into an even deeper, more abstract form.
The goal is to uncover hidden patterns or relationships that aren’t obvious in the original geometric layout.
- Everyday meaning: It means the system looks at the structured “position” an entity already has and then remaps it into a new space where subtle connections become clearer. This new space helps the system notice things like hidden groupings, shared tendencies, or underlying influences that weren’t visible before.
- Breakdown:
- Geometric embedding: The entity’s current internal representation — a cleaned‑up, structured description of what it is and how it relates to others.
- Latent mapping function: A learned transformation that takes that representation and projects it into a deeper, more abstract space.
- Latent coordinate: The final output: a new point that captures hidden features or relationships the system has discovered.
- Purpose: By moving entities into this latent space, the system can detect patterns that aren’t visible in the original geometric layout — like quiet similarities or indirect influences.
- In simple terms: It’s like taking a neatly organized map of people and then creating a second map that shows deeper, less obvious connections — the “hidden structure” behind the scenes.

This describes how the system decides which entities count as “near” a given one inside its internal space.
Any entity that falls within a small distance of the target is considered part of its local neighbourhood.
- Everyday meaning: It means the system looks at how far other entities are from a chosen one and keeps only those that are very close. These nearby entities form its immediate surroundings — the ones most likely to matter for local interactions or comparisons.
- Breakdown:
- Distance between entities: A measure of how far apart two entities are inside the system’s geometric space.

- Domain manifold: \[ M_d = \{\, h_i \mid i \in d \,\} \] — global neighbourhoods are typically subsets of domain‑specific manifolds.
Global Neighbourhood — Plain Explanation
This describes how the system identifies every entity that is connected to a given one through the network’s links.
Instead of looking only at nearby points, it includes all entities that have any direct connection to the target.
- Everyday meaning: It means the system gathers all entities that are linked to the chosen one in the underlying graph — no matter how far apart they are in geometric space. If there is an edge connecting them, they belong to its global neighbourhood.
- Breakdown:
- Graph connectivity: A list of all the links in the system showing which entities are connected to which others.
- Connected entities: Any entity that appears in the edge list alongside the target is considered part of its global neighbourhood.

- Base embedding: \[ h_i(t) = E_\theta\big(x_i(t),\, T\big) \] — foundational embedding from which both scales are derived.
Multi‑scale Embedding — Plain Explanation
This describes how the system blends two different views of an entity — a close‑up view and a whole‑system view — into one combined representation.
The mix is controlled by a knob that decides how much weight each view should have.
- Everyday meaning: It means the system builds a picture of each entity using both what happens in its immediate surroundings and what happens across the wider network. Neither view is taken alone; they are merged into a single, balanced description. How much each view matters can be tuned.
- Breakdown:
- Local view: Focuses on the entity’s closest neighbours — the ones that are very near in the internal space or strongly related. This captures fine‑grained, neighbourhood‑level detail.
- Global view: Looks at the entity’s position and connections in the entire system, not just nearby points. This captures broad patterns, long‑range links, and overall network structure.
- Mixing knob: A controllable setting that decides how much the final description leans toward the local view versus the global view. Turning it one way emphasises nearby context; turning it the other emphasises system‑wide context.
- Combined representation: The final result after blending both views according to the chosen mix. It gives a richer, multi‑scale picture of the entity, reflecting both its immediate environment and its role in the whole system.
- In simple terms: It’s like describing a city using both its neighbourhood streets and its place in the country’s map — and choosing how much each perspective should count.

Dynamic Embedding Update — Plain Explanation
This describes how the system refreshes an entity’s internal representation each time the situation changes.
When the entity’s state or its relationships update, the system produces a new, up‑to‑date embedding that reflects those changes.
- Everyday meaning: It means the system doesn’t keep a fixed picture of an entity. Whenever new information arrives — the entity changes, its connections shift, or the environment evolves — the system rebuilds the entity’s internal representation so it stays current and accurate.
- Breakdown:
- Updated entity state: The latest information about what the entity is doing or what condition it is in at the new time step.
- Updated relationships: The refreshed description of how the entity interacts with others — who it is connected to, influenced by, or similar to now.
- Embedding update step: A learned procedure that takes the new state and new relationships and produces a revised internal representation.
- New embedding: The final, updated snapshot of the entity inside the system’s geometric space — reflecting how it has changed since the previous step.
- In simple terms: It’s like updating someone’s profile every time their situation changes, so the system always works with the latest version.

This describes how much an entity’s internal representation changes from one moment to the next.
It compares the old version and the new version and measures the size of the difference.
- Everyday meaning: It means the system checks how much an entity has “moved” or “shifted” inside its internal space after an update. If the new representation is very different from the previous one, the drift is large. If it barely changes, the drift is small.
- Breakdown:
- Previous representation: The entity’s internal description at the earlier time step — the “before” picture.
- Updated representation: The entity’s new internal description after the system processes fresh information — the “after” picture.
- Difference between the two: The system subtracts the old representation from the new one to see what changed.
- Size of the change: It then measures how big that difference is, giving a single number that reflects how much the entity’s internal position has shifted.
- In simple terms: It’s like asking: “How far did this entity move between yesterday’s map and today’s map?”

Cross‑domain Geometric Mapping — Plain Explanation
This describes how the system takes an entity’s representation from one domain and translates it into the corresponding representation in another domain.
It is essentially a “conversion step” that preserves meaning while shifting the entity into a different geometric context.
- Everyday meaning: It means the system can take how an entity is represented in one setting — say, one region, sector, or category — and produce the matching version of that entity in another setting. The mapping ensures the entity keeps its identity and structure, even though the surrounding domain changes.
- Breakdown:
- Representation in domain A: The entity’s internal description as understood within domain A — shaped by the rules, relationships, and geometry of that domain.
- Cross‑domain mapping: A learned transformation that knows how to translate domain‑A representations into domain‑B representations while keeping the essential meaning intact.
- Representation in domain B: The resulting internal description of the same entity, now expressed in domain B’s geometric structure.

The result is a single combined space that contains every entity from every domain.
- Everyday meaning: It means the system takes the geometric layouts built for each domain — each group, region, category, or sector — and puts them together into one shared space. This unified space lets the system compare entities across domains and understand how different domains relate to one another.
- Breakdown:
- Domain‑specific spaces: Each domain has its own collection of entity representations, shaped by the rules and relationships inside that domain.

Non‑conceptual Latent Structure — Plain Explanation
This describes how the system extracts deep, subtle patterns from an entity’s geometric representation — patterns that cannot be neatly expressed in words or concepts.
It produces a latent construct that reflects structure the system “feels” but cannot verbalize.
- Everyday meaning: It means the system looks at an entity’s internal geometric representation and pulls out hidden structure that doesn’t map cleanly onto human concepts. These patterns may be diffuse, intuitive, or relational in ways that language cannot capture, but they still help the system understand how the entity behaves or fits into the larger geometry.
- Breakdown:
- Geometric embedding: The structured internal representation of the entity — the “shape” the system assigns based on its features and relationships.
- Nonlinear extraction: A transformation that digs into the embedding and identifies subtle, distributed patterns that are not tied to explicit concepts or labels.
- Latent construct: The resulting hidden representation, capturing aspects of the entity that are meaningful to the system but difficult to describe verbally.
- Purpose: This allows the system to work with information that is too complex, too abstract, or too intertwined to be expressed in ordinary conceptual terms — enriching its understanding of the entity’s role in the geometry.
- In simple terms: It’s like noticing a pattern in someone’s behaviour that you can’t quite put into words — you understand it, but you can’t explain it directly.

- Latent mapping: \[ z_i(t) = g_\theta\big(h_i(t)\big) \] — may produce alternative cluster structures in latent space.
Geometric Clusters — Plain Explanation
This describes how the system groups entities together based on how similar their geometric representations are.
Each group, or cluster, contains entities that “sit close” to one another in the internal space.
- Everyday meaning: It means the system looks at all entities, compares their internal geometric shapes, and gathers together the ones that resemble each other. Each cluster represents a natural grouping — entities that behave alike, share patterns, or occupy similar positions in the geometry.
- Breakdown:
- Geometric embedding: The internal representation of each entity — its position or shape inside the system’s geometric space.
- Clustering rule: A procedure that examines each embedding and decides which group it belongs to based on similarity or proximity.
- Cluster label: The identifier (like “cluster 1”, “cluster 2”, etc.) assigned to each entity once the system determines where it fits.
- Cluster set: The final collection of all entities that share the same label, forming a coherent group inside the geometry.
- In simple terms: It’s like sorting people into groups based on where they stand on a map — those standing close together end up in the same cluster.

< \delta
$$
- Title: Fidelity preservation

- Geometric distance: \[ d_{ij} = f\big(T_{ij}\big) \] — stability of distances may depend on fidelity constraints.
- Latent mapping: \[ z_i(t) = g_\theta\big(h_i(t)\big) \] — latent representations may inherit fidelity requirements from the base embedding.
- Structural drift: \[ \Delta h_i = \big\|\, h_i(t+1) - h_i(t) \,\big\| \] — indicates how fidelity violations may accumulate over time.
Geometric Fidelity Constraint — Plain Explanation
This expresses a requirement that the embedding must stay close to the original data.
The system is allowed to transform the input, but only up to a small amount — never so much that important information is lost.
- Everyday meaning: It means the system checks whether the embedded version of an entity still resembles the original input. If the embedding drifts too far, the system treats it as a distortion and prevents it. This keeps the representation trustworthy and faithful to the underlying variables.
- Breakdown:
- Original state: The raw input describing the entity before any geometric transformation.
- Embedded state: The transformed version produced by the embedding function — the entity’s position inside the geometric space.
- Embedding error: The difference between the embedded state and the original state, measured as a distance. This tells the system how much the embedding has altered the input.
- Distortion limit: A small threshold that the error must stay below. If the embedding changes the input too much, it violates the fidelity constraint.
- In simple terms: It’s like saying: “You can redraw this point in a new space, but don’t move it so far that it stops representing what it originally meant.”

- Geometric clusters: \[ C_k = \{\, h_i : \operatorname{cluster}(h_i) = k \,\} \] — cluster structures that may need to satisfy domain‑specific constraints.
Constraint Preservation — Plain Explanation
This expresses a rule the system must obey at every moment: certain structural constraints must always hold true.
No matter how the system evolves, the constraint operator must evaluate to zero, meaning the rule is perfectly satisfied.
- Everyday meaning: It means the system checks whether all required physical, ecological, economic, or structural rules are still being respected. If the constraint is violated, the system is in an invalid state and must correct itself. The constraint must hold exactly — not approximately.
- Breakdown:
- System state: All variables describing the system at a given time — everything that could influence whether constraints are met.
- Constraint operator: A rule or condition that evaluates the system state and determines whether it satisfies required structural limits.
- Zero condition: The operator must return zero, meaning the constraint is fully satisfied with no violation or residual error.
- Purpose: This ensures the system never drifts into impossible, unstable, or invalid configurations — keeping its evolution grounded in the rules of the domain.
- In simple terms: It’s like checking that a machine always obeys its safety limits — if the rule isn’t satisfied exactly, the system must stop or adjust.

- Joint manifold: \[ M_{\text{joint}} = \bigcup_{d \in D} M_d \] — includes both climate and economy domains, enabling cross‑domain coupling.
- Base embedding: \[ h_i(t) = E_\theta\big(x_i(t),\, T\big) \] — foundational embedding from which domain‑specific embeddings such as \(h_{\text{climate}}\) and \(h_{\text{econ}}\) are derived.
- Relationship tensor: \[ T_{ij} = \Phi\big(x_i,\, x_j\big) \] — influences geometric structure in both climate and economic domains.
Example: Cross‑domain Coupling — Plain Explanation
This shows how the system converts a representation from the climate domain into its corresponding representation in the economic domain.
It’s a translation step that keeps the meaning of the entity while shifting it into a different geometric context.
- Everyday meaning: It means the system can take how something is represented in climate terms — emissions, temperature trends, environmental behaviour — and translate that into how it should be represented economically. This lets the system understand how climate‑related structure influences or connects to economic structure.
- Breakdown:
- Climate‑domain representation: The geometric description of an entity inside the climate manifold — shaped by climate variables and relationships.
- Cross‑domain transformation: A learned mapping that knows how to reinterpret climate geometry in economic terms, preserving the entity’s identity while shifting domains.
- Economic‑domain representation: The resulting geometric description of the same entity inside the economic manifold — now expressed according to economic structure.
- Purpose: This enables the system to link climate behaviour with economic behaviour, supporting cross‑domain reasoning, forecasting, and integrated analysis.
- In simple terms: It’s like taking a point defined in climate coordinates and converting it into economic coordinates so both domains can talk about the same entity.

- Title: Geometric embedding update under system dynamics
- Meaning: Updates each entity’s geometric embedding using its new state and the updated relationship tensor. This rule ensures that geometric representations evolve consistently with the system’s dynamics.
- Symbols:
- \(h_i(t+1)\): Updated geometric embedding for entity \(i\) at time \(t+1\).
- \(E_\theta\): Learnable embedding function parameterised by \(\theta\).
- \(x_i(t+1)\): Updated entity state at time \(t+1\).
- \(T(t+1)\): Updated relationship tensor encoding interactions at time \(t+1\).
- \(\big(\cdot,\cdot\big)\): Function arguments specifying state and relational structure.
- \(=\): Equality defining the update rule.
- Related equations:
- Previous-step embedding: \[ h_i(t) = E_\theta\big(x_i(t),\, T\big) \] — embedding definition at the previous time step.
- Structural drift: \[ \Delta h_i = \big\|\, h_i(t+1) - h_i(t) \,\big\| \] — measures how much the embedding changes due to the update.
- Relationship tensor: \[ T_{ij} = \Phi\big(x_i,\, x_j\big) \] — defines pairwise interactions feeding into both \(T(t)\) and \(T(t+1)\).
- Geometric distance: \[ d_{ij} = f\big(T_{ij}\big) \] — influences neighbourhood‑based updates.
- Local neighbourhood: \[ N_i^{\text{local}} = \{\, h_j \mid d_{ij} < \epsilon \,\} \] — neighbourhood structure affecting the dynamics update.
Dynamics Update Rule — Plain Explanation
This describes how the system refreshes an entity’s geometric representation at each new time step.
When the entity’s state or its relationships change, the system produces a new embedding that reflects those updates.
- Everyday meaning: It means the system doesn’t keep a fixed picture of an entity. Whenever new information arrives — the entity changes or its connections shift — the system rebuilds its internal representation so it stays accurate and up to date.
- Breakdown:
- Updated state: The latest information about the entity at the new time step — what it is doing, how it behaves, or what conditions have changed.
- Updated relationships: The refreshed description of how the entity interacts with others, capturing changes in connections or influence patterns.
- Embedding update: A learned transformation that takes the new state and new relationships and produces a revised geometric representation.
- New embedding: The final updated internal position of the entity inside the geometric space — reflecting all changes since the previous step.
- In simple terms: It’s like updating a character’s profile every time the world changes, so the system always works with the latest version.
This representation allows the system to reason inside the true dimensionality of climate–economy–energy interactions without compressing them into simplified conceptual forms.
Geometry‑Aligned Representation: Algorithmic Construction
Step 2 operationalises the idea that internal representations should mirror the geometry of the target system rather than impose human‑defined abstractions. The pseudocode below translates the formal definitions into an ordered sequence of operations that a program can execute to build, update, and maintain a geometry‑aligned internal space. It shows how relationship tensors are constructed, how high‑dimensional embeddings and manifolds are formed, how multi‑scale structures and cross‑domain couplings are integrated, and how non‑conceptual geometric patterns are exposed to downstream inference. Each operation is arranged in dependency order, ensuring that geometric objects are instantiated only after the structures they rely on exist, thereby producing a coherent internal geometry \(G_{\text{int}}\) aligned with the state space \(S\) defined in Step 1.
