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
- Running a failing command with --silent (VERBOSITY_SILENT) exits with code 1 but completely suppresses exception rendering, while --quiet (VERBOSITY_QUIET) renders the exception message to error output
- Under --silent verbosity, isSilent() is true, isQuiet() is false, and input interactive mode is forced to false
- InputOption::VALUE_NEGATABLE defaults to null (tri-state unset) when omitted rather than false, sets true on --flag and false on --no-flag, and accepts boolean defaults in 8.1 while throwing LogicException on non-boolean defaults
- ArgvInput greedily consumes the next token as the value for VALUE_OPTIONAL options without an equals sign, leaving subsequent required positional arguments unfulfilled
- ArrayInput requires '--' prefix for option keys; passing an unprefixed key sets a matching InputArgument instead and leaves the option at its default value
- In ArrayInput, the '--' delimiter key immediately terminates parsing of all subsequent arguments and options
- QuestionHelper::ask() in non-interactive mode executes question validators but silently skips normalizers on the default answer
- ChoiceQuestion with an associative choice map returns the matching key string rather than the choice label, even when selected by label
