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
- maps.Keys extracts a slice containing all keys from a map
- maps.Values extracts a slice containing all values from a map
- maps.Clone creates a shallow copy of a map
- maps.Equal reports whether two maps contain identical key/value pairs
- maps.Copy copies all key/value pairs from src to dst
- maps.DeleteFunc deletes key/value pairs satisfying a predicate function
- slices.Sort sorts a slice of any ordered type in ascending order
- slices.BinarySearch searches for a target in a sorted slice and returns the index and presence flag
- slices.Contains and slices.Index locate elements within slices
- slices.Compact replaces consecutive runs of equal elements with a single copy
- constraints.Ordered type constraint permits type parameters supporting ordered comparison operators
