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
- WriteSnippet creates a header-and-footer bounded snippet in a new file
- WriteSnippet replaces an existing snippet while preserving surrounding content
- AppendNewLine appends content and ensures newline separation
- PrependLine inserts a line at the top and removes duplicates with the same prefix
- RemoveLine deletes the line matching a substring from the configuration file
