Reason: no major geometry red flags detected
2 protein-contact clashes 93% of hydrophobic surface is solvent-exposed (13/14 atoms). Large non-polar area without protein contacts incurs a desolvation penalty and will reduce binding affinity. Consider truncating or replacing the exposed fragment.

🚨Solvent-exposed hydrophobic surface — desolvation penalty likely
93% of hydrophobic surface is solvent-exposed (13/14 atoms). Large non-polar area without protein contacts incurs a desolvation penalty and will reduce binding affinity. Consider truncating or replacing the exposed fragment.
