The cover letter is clear about the threat model: these are input validation improvements, not security fixes per the standard Hyper-V trust model, but they align with the Confidential-VM trajectory where the host is not fully trusted. The v2 iteration addresses real issues flagged on v1 (the dead-on-arrival display from missing WIN8 fallback defaults, and the stale completion race). Both patches are small, focused, and target a single file. The commit messages are detailed and accurate. **Series verdict: Looks good overall with minor issues noted below.** --- --- Generated by Claude Code Patch Reviewer
