+
+| Service | Local URL or host port | Source |
+| --- | --- | --- |
+| Web app | `http://127.0.0.1:42130` | `pnpm dev:web` |
+| FastAPI backend | `http://127.0.0.1:42180` | `pnpm dev:api` |

+| Redis | `127.0.0.1:42379` -> container `6379` | `docker compose up -d redis` |
+
+Keep the deployed AMH/Nginx server mappings on the documented production ports, currently web `3000` and API `8000`. The uncommon ports above are the repo defaults for local testing only.

 The dashboard also includes lightweight saved views for local testing. Saved views are validated against the shared contract, proxied through the Next.js app, and persisted in Postgres using `GAMMASCOPE_DATABASE_URL` when available. If the Postgres-backed repository is unavailable at runtime, the FastAPI route falls back to in-memory saved views so local dashboard flows keep working.
