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.
MIT-0

Contract
- copystructure.CopierFunc registered on Config.Copiers executes custom deep copy logic for a specified type
- copystructure.CopierFunc is recursively invoked when the registered type is nested within structs, slices, and maps
- copystructure.CopierFunc returning an error halts Config.Copy and propagates that exact error back to the caller
- Deep copying via copystructure.CopierFunc ensures mutations on the copied value do not affect the original source value
