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
- log.NewLogfmtLogger formats structured key-value pairs into logfmt strings
- log.NewJSONLogger formats structured key-value pairs as valid JSON lines
- log.With preserves contextual key-value pairs across log invocations
- log.Timestamp dynamically evaluates timestamp Valuers on each log call
- level.NewFilter squelches debug messages and allows info and error messages
- log.NewSyncLogger provides thread-safe structured logging across concurrent goroutines
