final reply
settings.env doesn't contain a `RETRY_BACKOFF_MS` setting. The file only defines:

- `SERVICE_NAME=api`
- `PORT=8080`
- `LOG_LEVEL=info`
- `TIMEOUT_MS=30000`

Full harness trace — flagOn · seed 1

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.
