Some checks failed
verify / verify (push) Has been cancelled
The API and ingestion tools now use a fixed internal model gateway while governed profiles, embedding cache assignments, traceable citations, and stable API errors establish the boundaries required by later workflows. Constraint: The current Alibaba Cloud workspace rejects all three live model calls with authentication failures Rejected: Give the API or seed tools the Bailian key and direct egress | combines database access, cloud credentials, and public network access Rejected: Mix offline and Bailian vectors in one demo namespace | makes profile activation and retrieval ambiguous Confidence: high Scope-risk: moderate Reversibility: clean Directive: Keep Bailian credentials and egress exclusive to model-gateway and create a new immutable profile hash for any embedding identity change Tested: make verify; 121 backend tests; 14 frontend tests; fresh and populated Alembic upgrade-downgrade-upgrade; two idempotent offline seeds; Docker health and HTTP retrieval; isolated provider smoke Not-tested: Successful live Bailian responses because the supplied workspace credential currently fails authentication
