Diligence questions
- The dataset records 3 tracked suppliers for Realtek Semiconductor. Which of those edges are researched (named in a filing or primary source) versus segment-inferred, and what happens if one of them stops shipping?
- 2 of Realtek Semiconductor's tracked suppliers are a monopoly or leader (including ASE Technology, TSMC). Which of those are actually single-source for the process step you care about?
- Realtek Semiconductor is headquartered in Taiwan. What jurisdiction, export-control or logistics risk sits at that HQ, versus at the fabs or plants the filings actually name?
- Realtek Semiconductor trades as TWSE:2379. What does the latest reported period say about capacity and backlog versus the graph position above?
- Before treating any edge as a verified relationship, check the provenance labels on the company page and the method note at /methodology.
