There's no `data/index.csv` in the workspace — the only file in `data/` is `catalog.csv`. Let me know if you meant that one.

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.
