Published samples
- core-js 3.50.0: Demonstrate that core-js 3.50 captures the built-in URL.prototype.toString when installing a missing URL.prototype.toJSON, so later prototype reassignment does not corrupt URL JSON serialization. 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.

Compatibility matrix
Project-level observations and symbol/contract verifications are counted separately and never combined.
These counts do not distinguish how the symbol was called: overloads, argument shapes and options are pooled together. What a particular call shape does is proven by a sample's contract, not by these numbers.
