+# Definition — System
+
+**Premise:** 
+
+1. All ecological embeddings have geometric properties.
+
+2. Flux denotes the rate of information transfer across a surface within G.
+
+3. Dimensionality, Size, and Degrees of Freedom:
+	- *Dimension* — a particular direction along a Principal Axis. A direction, not a measurement.
+	- *Size* — the span or magnitude of a quantity along a single dimension.
+	- *Dimensionality* — the count of independent Principal Axes of G or any subdomain; equivalently, the number of degrees of freedom available within that domain.
+	- *Degrees of freedom* — coincide with dimensionality. Uncertainty in information transfer within a domain is a function of its degrees of freedom.
+	- *On common usage:* In architecture and civil engineering, "dimensions" typically denotes physical extents such as length, width, or height — these are sizes in the sense defined here, not dimensions. The two must not be conflated: dimension is direction; size is magnitude along a direction.

+
+A **system** S is defined as a triplet **(N, R, G)** such that:
+
+- **N** is a set of **nodes** — the networked things that constitute the system.
+- **R** is a set of **relationships** among nodes — including self-relationships, where a node in N relates to itself via a reflexive relation in R.
+- **G** is a set of **ecological embeddings** that defines the spatio-temporal adjacency of N and R within a hyper-dimensional space. G mediates R: the relationships in R are made persistent and meaningful by the ecological embedding G provides.
+
+---
+
+## Formal Constraints
+
+1. N and R may each be empty. The empty system (N = Ø, R = Ø) is valid — it is inert or idempotent or void in its informational content, but not ill-formed.
+
+1. A node n in N may hold a reflexive relationship (n, n) in R. In this case, n is simultaneously the sender and receiver of its own signal, ecologically coupled to itself via G. This is the minimal non-degenerate system: a single node with memory of itself.
+
+1. Information transfer within S is possible if and only if R ≠ Ø and |N| ≥ 1. A system with nodes but no relationships is degenerate — no transfer channel exists.
+
+1. Memory of S exists if and only if G is non-trivially structured — nodes in N have spatio-temporal adjacency within the ecological embedding G, and G mediates at least one relationship in R. A system with no ecological embedding, or with an unstructured one, has no memory even if N and R are non-empty.
+
+1. The cost of forgetting within S depends on the ecology encoded in G — the individual, organizational, cultural, and environmental context in which S is embedded. Where relationships in R are non-linear and observer-constituted, forgetting may be irreversible. Where they are linear and observer-independent, forgetting is recoverable from residual components or external records.

+
+## Boundary Cases
+
+| N | R | G | Name | Status |
+|---|---|---|---|---|
+| Ø | Ø | — | Empty or void system | Valid. Informationally inert and idempotent. |
+| ≠ Ø | Ø | — | Degenerate system | Valid. No transfer possible. No memory. |
+| {n} | {(n,n)} | Structured | Minimal system | Valid. Single node, reflexive relation, self-memory via G. |
+| ≠ Ø | ≠ Ø | Unstructured | Transfer-capable, memoryless | Theoretically possible but ecologically intangible. |
+| ≠ Ø | ≠ Ø | Structured | Fully realized system | Transfer and memory both available. |
+
+---
+
+## Corollary — Graph Representation
+
+Any system S can be represented as a graph where nodes in N are vertices and relationships in R are edges, including self-loops. An equivalent representation is a dictionary where keys are nodes in N and values are the sets of nodes they relate to via R. G is the ecological embedding in which that graph is physically instantiated and temporally persistent — without G, the graph is an abstract structure with no memory.
