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.

Case
HOW- Goal

- CommandRunner.run
- Command.argResults
- Command.globalResults
- Environment

Contract
- Calling CommandRunner.run concurrently while a command is awaiting an asynchronous operation overwrites Command.argResults and Command.globalResults mid-execution with the newly parsed values.
- argResults['job'] is 'A' before await, but changes to 'B' after await in the first invocation.
- globalResults['env'] is 'staging' before await, but changes to 'production' after await in the first invocation.
