SAP Sovereign Regions — what works where

When generating code or recipes for a SAP customer, always check region context first. China and KSA have no Anthropic/OpenAI models in AI Core; NS2 has a gated subset. Hardcoding a wrong model produces a 403 at deploy time — the highest-cost failure mode for sovereign pilots.

Decision rule

1. If the user has named a region (china, ns2, ksa, commercial / EU/US/AP), use it.
2. If they haven't but the prompt mentions sovereign keywords ("21Vianet", "FedRAMP", "Saudi", "国产化", "ITAR"), infer the region and confirm.
3. If still ambiguous, ASK before generating code.
