Accept Docker Compose's exact string representation of the fixed 1024-dimensional embedding contract while rejecting every widened or ambiguous value. Entry-level smoke tests now exercise the same environment shape used by the container. Constraint: The current local Bailian credential still returns 401 for all three capabilities and is not stored in Git. Rejected: Change the field to an unconstrained integer | would allow a runtime dimension that disagrees with vector(1024). Confidence: high Scope-risk: narrow Directive: Keep the database vector dimension and provider dimension locked together through an ADR-backed migration. Tested: make verify; 75 backend tests; 14 frontend tests; rebuilt provider-smoke image; normal Compose smoke reached all three provider endpoints. Not-tested: Successful live provider response remains blocked by external authentication.
