EG-03 · Provider-portable system
One behavioral contract operates across two materially different provider or runtime configurations and exposes non-equivalent behavior honestly.
- Elaboration
- The unchanged harness runs against both configurations. Provider-specific features are isolated and documented rather than hidden in shared logic. The engineer makes and defends a selection or non-equivalence decision from evidence.
