I need more information to process this PR. The title "fix: 11 difetti confermati dallo sweep dei log di produzione (08-19)" is in Italian and doesn't describe the specific user-facing changes.

Could you provide:

1. The PR description or commit messages with details about what was fixed?
2. What user-facing issues were resolved?

Without these details, I cannot determine if this PR contains user-facing changes or if it's purely internal bug fixes. Once you provide the specifics, I'll classify it appropriately for the changelog.
