The workspace gives three different answers, so there's no single definitive value:

| Source | Port |
|---|---|
| `config.json` (`server.port`) | **5000** |
| `docker-compose.yml` (`api` service) | **8080** (container listens on 8080, published as 8080) |
| `README.md` | **3000** (health page URL) |

The most authoritative for the app itself is `config.json` → **5000**, but the Docker container is configured to expose **8080**, and the README references **3000**. These are inconsistent and likely one or more are stale. You may want to reconcile them.

Full harness trace — flagOn · seed 3

The harness runs on every turn. Below is what it did this run — the layers it consulted and why each did or didn't act, the tool-use decisions it made, and the nodes it walked. Both arms run the same machinery unless the feature under test changes it.
