Section 21 of 104
19. Permitted Variability and Extension Boundaries
Stable section ID: S05-CON-016-SECTION-21 · 27 content blocks
System05 shall permit wide implementation variability within controlled constitutional and Interface boundaries.
Permitted variability may include:
internal Product geometry;
structural material;
manufacturing process;
fastener or locking technology;
sensor technology;
software language and infrastructure;
communication technology;
regional dimensions and units;
architectural form;
supply-chain organization;
human or robotic assembly method;
maintenance and commercial service models.
Variation shall be permitted when the implementation satisfies applicable requirements for safety, performance, Compatibility, identity, traceability, inspectability, lifecycle support, and verification.
Extensions may introduce new capabilities, Interface classes, data fields, Profiles, Components, or automation functions. An extension shall declare:
its purpose and scope;
governing authority;
affected entities;
compatibility consequences;
Version and status;
verification requirements;
migration and retirement provisions.
Extensions shall not redefine existing constitutional terms, reuse existing identifiers for different concepts, or silently change mandatory Interface behavior.
Experimental extensions shall remain distinguishable from production-authorized extensions.
Proprietary internal technology may be permitted, but essential information required for safety, integration, verification, maintenance, and replacement shall remain available to authorized parties.
Where an implementation falls outside an established Compatibility Envelope, it shall be treated as a new extension, alternative solution, or controlled Deviation rather than ordinary variability.
