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
- assert GetStringSlice returns one comma-containing element for a comma-separated environment value
- assert Unmarshal returns two elements for that same comma-separated environment value
- assert GetStringSlice splits a whitespace-separated environment value while Unmarshal retains it as one element
- assert GetStringSlice and Unmarshal both return two elements when a bound pflag.StringSlice has already parsed the comma
- assert a YAML sequence returns two elements for both APIs while a YAML comma-separated scalar remains one element in GetStringSlice and becomes two through Unmarshal
