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.

Contract
- copystructure.Copy deeply duplicates nested structs, maps, slices, and pointers without sharing state
- copystructure.Must unwraps the copied value directly and panics on unsupported errors
- copystructure respects struct tags for ignored fields and shallow copied references
- copystructure.Config with custom CopierFunc overrides default deep copying behavior
