| 8 | +# Definition — System |
| 9 | + |
| 10 | +**Premise 1:** All ecological embeddings have geometric properties. |
| 11 | + |
| 12 | +**Premise 2:** Flux denotes the rate of information transfer across a surface within G. |
| 13 | + |
| 14 | +--- |
| 15 | + |
| 16 | +A **system** S is defined as a triplet **(N, R, G)** such that: |
| 17 | + |
| 18 | +- **N** is a set of **nodes** — the networked things that constitute the system. |
| 19 | +- **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. |
| 20 | +- **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. |
| 21 | + |
| 22 | +--- |
| 23 | + |
| 24 | +## Formal Constraints |
| 25 | + |
| 26 | +1. N and R may each be empty. The empty system (N = Ø, R = Ø) is valid — it is informationally inert but not ill-formed. |
| 27 | + |
| 28 | +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. |
| 29 | + |
| 30 | +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. |
| 31 | + |
| 32 | +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. |
| 33 | + |
| 34 | +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. |

| 38 | +## Boundary Cases |
| 39 | + |
| 40 | +| N | R | G | Name | Status | |
| 41 | +|---|---|---|---|---| |
| 42 | +| Ø | Ø | — | Empty system | Valid. Informationally inert. | |
| 43 | +| ≠ Ø | Ø | — | Degenerate system | Valid. No transfer possible. No memory. | |
| 44 | +| {n} | {(n,n)} | Structured | Minimal system | Valid. Single node, reflexive relation, self-memory via G. | |
| 45 | +| ≠ Ø | ≠ Ø | Unstructured | Transfer-capable, memoryless | Theoretically possible but ecologically intangible. | |
| 46 | +| ≠ Ø | ≠ Ø | Structured | Fully realized system | Transfer and memory both available. | |
| 47 | + |

| 50 | +## Corollary — Graph Representation |
| 51 | + |
| 52 | +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. |
