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
- getCallerFile returns the caller file path of the invoking function at default position 2
- getCallerFile inspects callers at custom stack depth positions
- getCallerFile throws TypeError when position depth exceeds or equals Error.stackTraceLimit
- getCallerFile preserves existing Error.prepareStackTrace handler across invocations
- getCallerFile returns undefined when requested stack position exceeds stack depth within limits
