49. Interface
Stable section ID: S05-CON-015-SECTION-50 · 14 content blocks
An Interface is the defined boundary through which independently developed engineering entities connect, transfer forces or resources, exchange information, align, communicate state, permit inspection, or interact with humans, tools, software, AI systems, and robots.
Interfaces may be:
structural or mechanical;
geometric or dimensional;
electrical or electronic;
hydraulic, pneumatic, or thermal;
environmental or fire-related;
digital, semantic, or communication-based;
operational, inspection, maintenance, or robotic;
hybrid and multidomain.
An Interface defines the conditions of interaction without unnecessarily prescribing the internal design of the participating entities.
Interface compatibility requires more than geometric fit. It may depend on performance class, load direction, material behavior, environmental exposure, version, protocol, assembly state, safety condition, inspection procedure, and lifecycle responsibility.
Every constitutional Interface shall possess a persistent identity, defined scope, responsible parties, version, compatibility rules, failure behavior, and verification method.
The long-term stability of System05 shall be achieved primarily through stable and governed Interfaces rather than permanently fixed implementations.
