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
- Command subclasses defining static getDefaultName() have a null name in Symfony Console 8 because getDefaultName() was removed in favor of #[AsCommand], and Application::addCommand() throws LogicException for empty names.
- AsCommand attribute class is final in Symfony Console 8 and populates command name and description upon instantiation.
- Closures attached to Command via setCode() must return an integer exit code and throw TypeError when returning null.
- OutputInterface defines VERBOSITY_SILENT at level 8, where isSilent() returns true and even VERBOSITY_QUIET output is suppressed.
