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.
MIT-0

Contract
- level.NewFilter allows log events at or above configured AllowInfo level (info, warn, error) and squelches debug
- level.NewFilter passes unleveled log events through unmodified by default
- level.NewFilter squelches unleveled logs and returns custom ErrNoLevel when SquelchNoLevel(true) is configured
- level.NewFilter returns custom ErrNotAllowed error when a disallowed log event is squelched
- level.NewFilter with AllowNone squelches all leveled log events
- level.NewFilter dynamically configures allowed levels using level.Parse and level.Allow
