Execution surfaces
| Surface | Use for | Visible paths |
|---|---|---|
| Hermes terminal and file tools | Sandbox-local text, scripts, indexes, and uploaded inputs | /sandbox/... and sandbox /tmp/... |

Paths reported by Blender and task-owned host output paths |
| External operator | Copying files across the boundary with nemohermes sandbox upload or download |
