# ai-service
FastAPI service for drug resolution, guarded retrieval, printed-page citations,
and PostgreSQL retrieval traces.
Local infrastructure:
```powershell
docker compose -f ..\..\infra\docker\docker-compose.yml up -d postgres qdrant
python -m migrate
uvicorn main:app --reload
```
`GET /health` is always available. `POST /v1/rag/query` requires structured
`subject_scope` and `intent`; unknown/non-human/recommendation requests fail
closed. The default `EMBEDDING_PROVIDER=disabled` intentionally leaves the RAG
backend unavailable until the collection and matching query embedder are
configured.
`EMBEDDING_PROVIDER=local-smoke` is only for local plumbing checks. Its hashing
vectors are deterministic but not semantic and must not be used for retrieval
quality claims. Bedrock is not called by this service and no IAM change is
required.
