Published samples

• http-cache-semantics 4.3.0: CachePolicy, CachePolicy.storable, CachePolicy.stale Built ? 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.
