What the evidence preview establishes

The physical evidence was consistent with excessive die temperature producing internal material degradation and a parametric change rather than an immediate catastrophic open or short.

Why this case matters

A parametric IC failure can preserve continuity while heat changes internal materials or device characteristics. Correlate electrical drift with die-centered residues and coating damage while accounting for decapsulation artifacts.
