## What changed
Use `resolve_for_enforcement` when preparing Windows restricted-token and elevated sandbox overrides, preserving read-only carveouts at volume roots. Expand deny-read ACL targets from the resolved permissions.
Use the same resolution in MXC policy preparation when volume roots do not require materialization, while retaining special handling for symbolic root denies.
## Testing
Add regression coverage for read-only carveouts in a volume-root workspace. Extend the Windows package smoke test to verify that a helper-created log matching a deny glob cannot be read while a neighboring allowed file remains readable.
