The changes systematically replace unchecked arithmetic (`offset + len`, direct subtraction) and unchecked array indexing with their checked/fallible equivalents (`checked_add`, `checked_sub`, `.get()`). Since all the hardened values originate from firmware (VBIOS headers, token entries, falcon descriptors), these are legitimate trust boundaries where defensive programming is warranted. The series is clean, well-structured, and each patch is focused on a specific function or code path. The diffs are small and easy to verify. Overall this looks good and ready to merge with minor comments below. **Verdict: Series looks good. A few minor observations but nothing blocking.** --- --- Generated by Claude Code Patch Reviewer
