Reason: no major geometry red flags detected
3 protein-contact clashes 3 intramolecular clashes 62% of hydrophobic surface is solvent-exposed (10/16 atoms). Large non-polar area without protein contacts incurs a desolvation penalty and will reduce binding affinity. Consider truncating or replacing the exposed fragment.
