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
- assert RichHandler defaults to markup=False unlike Console(markup=True), preserving literal tags unless extra={'markup': True} or handler markup=True
- assert RichHandler(markup=True) raises rich.errors.MarkupError on unescaped closing tags like [/status] in logged strings, which escape() or extra={'markup': False} prevents
- assert Formatter format strings with %(asctime)s or %(levelname)s cause duplicated level badges and timestamps inside message columns, while %(message)s keeps columns clean
- assert Formatter.datefmt overrides RichHandler.log_time_format when attached, while log_time_format acts as fallback when formatter is None
- assert omit_repeated_times=True blanks timestamps for consecutive records within the same second, while omit_repeated_times=False prints timestamps on every record
- assert ReprHighlighter and keyword highlighting style numbers and HTTP verbs by default, and suppressing highlighting requires highlighter=NullHighlighter() and keywords=[]
- assert rich_tracebacks defaults to False emitting plain string tracebacks, while rich_tracebacks=True renders formatted Traceback boxes with tracebacks_show_locals inspecting frame variables
- assert show_time=False, show_level=False, show_path=False strip Rich's structural columns while LogRender expands message to console width
- assert RichHandler initializes seamlessly in logging.config.dictConfig with custom formatters and rich_tracebacks
