-- Exposes three endpoints consumed by the Cloudflare Worker middleman
-
-## Endpoints
-
-| Method | Path | Purpose |
-|---|---|---|
-| `GET` | `/health` | Liveness probe — used by keep-alive GitHub Actions |
-| `GET` | `/manifest` | Proxies + caches `manifest.json` from the materials repo |
-| `POST` | `/retrieve` | Embeds query, searches index, returns scoped top-k chunks |
-
-## Local Development
-
-```bash
-pip install -r requirements.txt
-uvicorn main:app --reload --port 7860
-```
-
