Got it. Tracking:

1. **API rate limit** — 6,000 requests per minute.

Send the next fact whenever you're ready. If you'd like these persisted beyond this conversation, I can save them to a file (e.g. `/tmp/service-facts.md`) — just say the word.

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.
