---

## Findings

### **No Issues Found**

This patch modifies only the `.mailmap` file to update the contributor's email address mapping. The mailmap format is correct: the new canonical address appears first, followed by the old address in angle brackets.

**Verification:**
- No C code changes
- No API changes
- No ABI changes
- No documentation changes requiring release notes
- Mailmap syntax is correct
- No correctness bugs possible in a mailmap-only change
- No style issues (mailmap is not subject to C coding standards)
- No forbidden tokens
- No process violations

---

## Conclusion

**This patch is acceptable as-is.** It is a simple administrative change that follows the mailmap format and requires no further modifications.
