Greptile Summary

Updates two PyTorch test reference implementations for clamped SwiGLU to express upper and lower clamping with explicit torch.where operations.

• Replaces the GLU branch’s upper clamp in both references.
• Replaces the linear branch’s two-sided clamp in both references.

Confidence Score: 5/5

The PR appears safe to merge because the updated test references preserve the production clamped SwiGLU semantics.

The explicit conditional clamps preserve forward values and pass gradients through at the exact limits, matching the production kernel behavior in both changed test paths.

Important Files Changed

Filename	Overview
tests/pytorch/test_fusible_ops.py	The two reference implementations now match the production kernel’s inclusive clamp-boundary gradient semantics without introducing an actionable issue.
