63. Interface Stability and Controlled Evolution
Stable section ID: S05-CON-014-SECTION-65 · 13 content blocks
Interface stability shall receive higher lifecycle priority than the convenience of any individual implementation.
Interfaces should remain usable across multiple generations of Components, Modules, Cartridges, tools, software systems, and buildings.
An Interface shall evolve only when justified by:
- Identified safety needs.
- Verified incompatibility.
- Required performance improvement.
- Unavoidable regulatory change.
- New capability that cannot be introduced compatibly.
- Evidence that the existing Interface no longer achieves its intended outcome.
Evolution shall include impact analysis, version assignment, compatibility classification, transition strategy, verification, publication, and notice to affected participants.
New optional capability may be added without breaking compatibility only when legacy implementations can safely ignore, reject, or operate without it.
Installed buildings and long-life assets shall not be abandoned merely because a newer Interface generation exists. Continued-use conditions, adapters, replacement paths, and support periods shall be defined.
Silent changes in geometry, meaning, units, state behavior, or safety assumptions shall be prohibited.
