Report 2 provides the most balanced and coherent evaluation among the three, highlighting core strengths (per-user storage, size/extension checks, metadata persistence) and notable security gaps (absence of antivirus scanning, inconsistent MIME handling, unsafe deletion logic, cloud-credential risks). The improved assessment recommends hardening steps such as integrating antivirus scanning, standardizing MIME/extension mapping across languages, replacing glob-based deletions with exact mappings, enforcing strict access controls and audit logging, and enforcing least-privilege, rotated credentials for cloud storage.
