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
- detectNewline returns \r\n when CRLF is the dominant newline character
- detectNewline returns \n when LF is dominant or when LF and CRLF counts are equal
- detectNewline returns undefined when the string contains no newlines
- detectNewline throws TypeError when called with a non-string argument
- detectNewlineGraceful returns dominant newline character or defaults to \n when no newline is present
- detectNewlineGraceful returns \n gracefully for non-string inputs without throwing
