PR Summary

• Lessened Severity in Code Inspection The errorLevel factor in our code inspection tool configuration has been decreased from 2 to 1 in the psalm.xml file. This change causes our code analyzer to be less strict, catching only more severe issues, which could potentially make the development process smoother and more focused on broader system stability concerns.
