Published samples

• anyhow 1.0.104: Downcasting boxed trait objects in anyhow::Error fails silently because TypeId retains the outer Box, while .context() unwraps transparently and into_boxed_dyn_error bridges back to std::error::Error 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.
