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
- BufferedConsole logs standard output levels (log, info, warn, error, debug) into an in-memory buffer with type, message, and caller origin
- BufferedConsole.write appends structured log entries directly to a target buffer array
- BufferedConsole manages nested indentation levels for grouped logs with group and groupCollapsed while groupEnd resets indentation
- BufferedConsole tracks named timers with time and timeEnd and named counters with count and countReset
- BufferedConsole.assert logs an AssertionError entry when evaluated condition is falsy and ignores truthy conditions
- getConsoleOutput formats buffered console log entries into indented output strings with colorized log types and stack traces
- captureConsoleLogs intercepts global console output during function execution and restores the original global console on completion
- CustomConsole writes console entries directly to custom writable stdout and stderr streams
- NullConsole requires writable streams in constructor and silences all console output without throwing
