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
- StreamOutput does not close its underlying stream resource when destroyed, leaving the file descriptor open unless explicitly closed with fclose by the caller
- ConsoleOutput caches its stdout and stderr streams in private static variables, sharing the identical stream resource across separate ConsoleOutput instances
- OutputFormatter retains unclosed tag styles on OutputFormatterStyleStack across separate format and write calls, propagating styles into subsequent messages until explicitly closed with </>
- QuestionHelper on encountering EOF from a StreamableInputInterface permanently sets isInteractive to false on the input instance, silently disabling interactive prompts for all subsequent questions
- ProgressBar instantiated with ConsoleOutputInterface writes progress output to getErrorOutput() (STDERR) instead of STDOUT, and ProgressBar::finish() omits a trailing newline
- BufferedOutput::fetch() destructively drains the internal buffer rather than caching it, returning an empty string on subsequent calls
- Cursor::hide() and Cursor::show() emit the ANSI sequences \x1b[?25l and \x1b[?25h\x1b[?0c without resetting cursor visibility upon command completion or object destruction
