In `@scripts/vulnerability_report.py`:
- Around line 328-334: The guard in vulnerability_report.py is inverted in the
days statistics block, so the empty-input case still divides by zero and the
non-empty case returns zeros. Fix the logic around the days_stat assignment so
the sum/len and median calculations in the relevant branch run only when days
has values, and the fallback zero values are used only when days is empty. Use
the days_stat handling near the existing median(days) call to locate and correct
the branch condition.

🎯 Functional Correctness | 🔴 Critical | ⚡ Quick win
Inverted division-by-zero guard breaks both branches.
The condition is reversed. When days is empty, if not days: is true and sum(days) / len(days) evaluates 0 / 0, raising ZeroDivisionError — the exact case the comment says it avoids. When days is non-empty, the else branch forces avg/median to 0, discarding the real values. So this function crashes on empty input and returns incorrect statistics for every non-empty input.
🐛 Proposed fix
# avoid division by zero
- if not days:
+ if days:
days_stat["avg"] = sum(days) / len(days)
days_stat["median"] = median(days)
else:
days_stat["avg"] = 0
days_stat["median"] = 0📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
