SIE.4:12 - Relations

• SIE.2 supplies exact endpoint senses, editions, profiles, authority limits, and model gaps.
• SIE.3 is a conditional external return when available models cannot express a required endpoint distinction.
• SIE.5 consumes rows that expose a load-bearing cross-source identity question.
• SIE.6 uses correspondences to decide which source claims are comparable or composable without erasing scope or conflict.
• SIE.7 consumes only accepted rows under their stated use and loss conditions; it adds executable transformation semantics.
• SIE.10 tests correspondence truth and use qualification independently from mapping execution.
