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
- chalk default export is a styling function with Instance constructor and undefined Chalk property in chalk 4.x
- chalk.Instance with level 3 produces 24-bit TrueColor ANSI escape sequences for rgb, hex, and bgHex colors
- chalk.Instance with level 2 downsamples 24-bit rgb and hex colors to 256-color palette ANSI escape codes
- chalk.Instance with level 1 downsamples rgb and hex colors to basic 16-color ANSI escape codes
- chalk.Instance with level 0 disables ANSI color sequences and returns plain unstyled strings
- mutating the level property dynamically updates color downsampling on an existing chalk instance
- nested styling re-opens the enclosing color code immediately after the nested color close code
- chained style modifiers apply opening and closing ANSI codes in inverse order
- variadic arguments passed to style functions are concatenated with spaces
- passing a Symbol to style functions throws a TypeError during string coercion
