Structural models and scenario templates
This section records the formal model families used in the atlas and presents scenario templates that enable comparative structural study. Models are framed as neutral representational constructs: they describe how labeled resources flow through segmented components, how dependencies mediate interactions, and how constraint sets delimit feasible configurations. Each model family includes a concise formal description, a canonical diagram, and a procedural note describing how to compose or decompose instances for scenario comparison. The emphasis is on reproducible representation and clear annotation of assumptions rather than on numerical parameterisation. Practitioners of conceptual modelling may use these templates to map hypothetical arrangements, inspect structural properties, and trace the implications of alternative interface contracts or constraint sets.

Structural models
Structural models in the atlas formalize arrangements as labeled graphs and layered compositions that document the roles of segments, the topology of interconnections, and the transformation operators applied across interfaces. A canonical structural model begins with a segmentation layer that enumerates nodes and assigns role labels; a connectivity layer annotates directed edges with interaction types and coupling metadata; a constraint layer specifies boundary conditions, normalization practices, and classes of permissible adjustments; and an operational layer records pathway operators and transition predicates. The descriptive format supports explicit separation between representational commitments and implementation choices, so that comparisons highlight structural differences rather than parameter variations. Model entries include a minimal formal skeleton, a labelled diagram for schematic inspection, and a short protocol for generating variant instances. The written material focuses on representational clarity and taxonomy so that researchers can adopt, adapt, and compare models in a neutral, reproducible manner.

Scenario comparison methods
Scenario comparison within the atlas employs a structured protocol that isolates representational choices, records constraint sets, and enumerates adjustment pathways to enable direct structural contrasts. A scenario is specified by (1) a canonical instance of a structural model with explicit node and edge labels, (2) a declared set of constraints and normalization rules, and (3) a chosen collection of pathway operators with initiation and termination predicates. Comparative analysis proceeds by aligning models on shared vocabulary, computing differences in topology and constraint regimes, and tracing how selected pathway sequences propagate changes through connected components. The protocol encourages documenting all representational assumptions and annotating diagrams with edge and node metadata so that comparisons remain transparent and reproducible. This method is descriptive and analytic; it does not include empirical validation steps or claims about real-world outcomes, but it enables rigorous interrogation of structural alternatives and the articulation of hypotheses for subsequent research or theoretical refinement.

Formal notation and representation
The atlas adopts a compact formal notation to promote reproducible description. Notation constructs include typed node identifiers, directed labeled edges with payload descriptors, constraint predicates expressed as domain restrictions or inequality relations, and pathway operators described as mapping functions on labelled vectors. Where helpful, canonical abbreviations are provided alongside explicit expansion forms to reduce diagram clutter while preserving semantic clarity. Visual diagrams pair the compact notation with an annotated legend so that readers can reconstruct full formal statements when needed. Representation choices deliberately avoid prescriptive algorithmic detail; instead, the notation focuses on clear semantics for structure, coupling, and transformation. This approach supports analytic work that reasons about representational consequences, taxonomy alignment, and the formal comparison of structural alternatives without embedding operational or performance claims into the notation itself.

Model limitations and usage guidance
Models and scenarios in this atlas are conceptual constructs intended for analytical study. They do not represent calibrated systems, empirical forecasts, or operational templates. Users should treat them as schematic descriptions useful for comparative reasoning, taxonomy development, and hypothesis articulation. Limitations to note include the abstraction of temporal dynamics to pathway operators rather than full process simulation, the omission of implementation-level performance metrics, and the reliance on declared constraints which may not capture externalities present in empirical systems. The atlas therefore encourages readers to document representational assumptions explicitly, to use the notation and templates to generate reproducible comparative artifacts, and to supplement atlas models with domain-specific empirical work when seeking implementation-appropriate detail. All content remains neutral and descriptive and is not intended as advice or as a basis for action that assumes real-world effect.
Usage guidance
Use models for conceptual mapping and comparison; they are not operational specifications.
