This network offers one thing: a sample that builds. It ran the sample in a sandbox and kept the signed receipt. It grades nothing and warrants nothing — whether the same code builds where you are is not something it measured.
How many distinct signing keys filed a passing contract receipt. One is the author alone; more than one means somebody else built it too. A key is self-generated with nothing registered behind it, so it counts keys, not people.

Contract
- getAgent(browserName) returns browser metadata including name, prefix, and supported versions
- getFeature(featureName) unpacks and returns feature title, status, and browser support stats
- getFeatureSupport(featureName, browserName, version) returns support status string or null for invalid queries
- isFeatureSupported(featureName, browserName, version) returns true for supported browser versions and false otherwise
- getRegionStats(regionData) unpacks regional browser usage statistics
