- serde 1.0.229: Disabling chrono default features strips Utc::now and Local which require the clock feature rather than std, while serde support requires an explicit opt-in serde feature and serializes DateTime as an RFC 3339 string 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.
