# Code Review — Step 4

Verdict: APPROVED

## Findings

No blocking findings.

The only code change wraps the underlying timezone load error with `%w`, preserving the `errResolveCalendarDatesTimezone` sentinel while retaining the original cause. The Step 4 status updates are consistent with the verification commands run during review.
