## What changed
- Limit elevated interactive setup to provisioning sandbox identities and proxy settings; do not include caller workspace or ACL roots in its payload.
- Always run the non-elevated setup refresh during sandbox activation so the current permission profile supplies read, write, and deny paths, including when provisioning was completed previously.
- Add an `interactive-provision` setup mode that performs provisioning without the full ACL setup path.
## Testing
- Verify elevated provisioning payloads contain no caller ACL roots and use the new mode.
- Verify the setup helper accepts `interactive-provision` payloads.
