final reply
The billing API listens on port **9271**. `billing/server.js` doesn't hardcode it. It reads the `billing` value from `config/ports.json`.

Full harness trace — flagOn · seed 2

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.
