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.
The Stage 1 foundation now proves provider contracts with mocks and validates PostgreSQL/pgvector ingestion, approval binding, retrieval, reranking, and idempotency using only synthetic data. Live Bailian validation remains gated on rotating the exposed key.
Constraint: The key shown in chat is compromised and cannot be used or committed
Rejected: Mark Stage 1 complete from mock and offline results | real three-model smoke is still required
Confidence: high
Scope-risk: moderate
Reversibility: clean
Directive: Do not enable real-data ingestion until Stage 3 cloud approval and outbound manifest controls are enforced end to end
Tested: make verify; 41 pytest tests; strict mypy; Ruff; Compose config; pinned image build; empty-volume migration; role denial; two idempotent 20-vector seeds; database restart persistence
Not-tested: Live Bailian calls require a newly rotated key; React product UI is not implemented
