Glossary & Reference

A Module is an independently defined physical, digital, logical, or hybrid engineering unit that performs one or more coherent functions while interacting with other entities through declared Interfaces.

A Module should possess:

a distinct identity and boundary;

defined responsibilities;

controlled Interfaces;

configuration and version information;

compatibility conditions;

lifecycle and replacement requirements;

applicable verification status.

An Assembly is a structured combination of Components, Cartridges, Modules, or Subassemblies that collectively performs a larger engineering function.

Assembly does not eliminate the individual identities of its constituents. Parent-child relationships, interface connections, configuration states, and replacement history shall remain traceable.

Module and Assembly are context-dependent classifications. A Module within one architecture view may itself contain multiple Submodules and Assemblies.

Assemblies should preserve independent replacement and fault isolation where practical. Replacement of one Module should not require destruction of unrelated Modules unless required by structural safety, fire protection, environmental continuity, or another verified system condition.
