Adds a portable sealed-tool source contract while preserving Linux memfd sealing. Windows Driver Host verifies the owner executable, stages and re-attests a private copy, and passes only that VerifiedFile to the LPAC sandbox. The Windows platform re-verifies the staged PE, grants temporary read+execute authority to the unique LPAC SID, publishes a host-controlled tool table, and revokes authority on exit. The owner source is never mounted into the child. Includes a native fixture proving the staged copy still executes after the owner source is mutated and cannot be opened for write by the child. Heavy Rust/Windows validation is intentionally delegated to GitHub Actions.
