Key Structural Insight
The invisible monopoly. p=10, s=1, h=1. Without EDA, TSMC and NVIDIA are paperweights.

Scoring Rationale
Duopoly in Electronic Design Automation. Without Synopsys or Cadence, no one on Earth can design a chip. Not NVIDIA, not Apple, not TSMC's customers. Decades of proprietary formats, libraries, and design rules.
