Vendor–Provider Bridge
The connective tissue between the vendor transparency system and the testing-provider system.
Instead of asking readers to mentally join two compare pages, this page surfaces the strongest relationship paths directly: which vendors route into which providers, how those links appear, and what kind of evidence sits behind them.
Start here if you want the shortest explanation of what each bridge type actually means.
Jump directly to the strongest vendor ↔ provider relationships in the current public system.
Use the transparency view when you want to understand the vendor side before following the bridge back here.
The relationship layer matters because the evidence types differ
Not all vendor-to-provider links mean the same thing. Some are live verification paths. Some are vendor-hosted provider-authored documents. Some are simply vendor claims. Keeping those separate is what makes the broader trust system more honest.
