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.

HOW- Goal

Contract
- stack.Caller returns a Call record for a stack frame with valid PC and function name
- stack.Trace returns a CallStack capturing the sequence of function invocations
- stack.Call formats function name, source file and line number with fmt verbs %n, %s, %d
- stack.CallStack.TrimBelow and TrimAbove truncate stack frames relative to a Call record
