| 1 | //! Windows sandbox implementation (best-effort placeholder). |
| 2 | //! |
| 3 | //! Windows sandboxing can be implemented using: |
| 4 | //! - Windows Sandbox (full isolation) |
| 5 | //! - AppContainer (process isolation) |
| 6 | //! - Restricted tokens (reduced privileges) |
| 7 | //! |
| 8 | //! This module selects a preferred approach and exposes helpers used by the |
| 9 | //! sandbox manager. Full enforcement should be implemented in a helper binary. |
