Release digest
Fixed
- RAG-EMBEDDING-LOCATION-SPLIT (AI Runtime) — Vertex-backed RAG embeddings
now use
RAG_EMBEDDING_LOCATIONinstead of the Gemini model location alias, so Gemini preview rollouts can useGEMINI_LOCATION=globalwithout movingtext-embedding-004lookups away from their regional endpoint.
Internal
- Added focused regression coverage proving the Vertex embedding service uses
the dedicated embedding location even when Gemini model calls are configured
for
global. - Updated the AI runtime architecture notes and deployment environment
inventory for the new
RAG_EMBEDDING_LOCATIONoperator contract. Public docs decision: no public documentation change is required because this is an internal runtime/deployment control and does not change user-facing product behavior, legal language, investment guidance, report output, or public API setup.
