Windows currently has no process-write backend for the generic sandbox profile, so enabling sandboxing must reject model-originated processes rather than run them with ordinary user authority. This draft adds an independent Zig implementation that can be compared with the Rust prototype before choosing a production direction.
The standalone helper derives root-specific restricting SIDs, provisions narrow NTFS capability and deny ACEs, creates a
WRITE_RESTRICTEDtoken, and starts the target suspended with an explicit handle list before assigning it to a kill-on-close Job. The TypeScript backend only translates the normalized profile, resolves the helper beside the Kilo executable or through an explicit development override, and preserves fail-closed behavior.The backend remains behind
KILO_WINDOWS_SANDBOX_PROTOTYPE=1. ACL journaling and recovery, race-proof recursive provisioning, future-name.gitprotection, and a dedicated parent-death lease remain release blockers, so the helper is emitted only as a short-lived comparison artifact and is not included in CLI or VSIX packages.Part of #11542.
