The series progresses logically: first fixing real bugs (patches 1-7), then incrementally refactoring to remove unnecessary abstractions (patches 8-16), and finally cleaning up unused code and improving organization (patches 17-22). The core value of this series is replacing unchecked arithmetic and array indexing with checked operations (`checked_add`, `checked_sub`, `checked_mul`, `.get()`, `FromBytes`) throughout the VBIOS parsing code. Since the data comes from firmware, these are genuine hardening improvements that prevent panics from malformed BIOS ROMs. The series is at v5 and has accumulated Reviewed-by tags from Joel Fernandes and John Hubbard on most patches. The refactoring to remove `FwSecBiosBuilder` and collapse the two-FWSEC-image model into a single contiguous block is a significant simplification. **Overall: This series looks good to merge.** The hardening changes are correct, the refactoring is well-motivated, and the series is well-split with each patch doing one thing. A few minor observations below. --- Generated by Claude Code Patch Reviewer
