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
- zapslog.NewHandler wraps a zapcore.Core to provide a slog.Handler bridging structured log records to Zap encoders.
- zapslog.NewHandler respects slog log levels, properly emitting enabled levels and suppressing filtered levels.
- zapslog.WithName annotates emitted log entries with the configured logger name.
- zapslog.WithCaller attaches caller filename and line number to emitted log entries.
- zapslog.AddStacktraceAt records stack traces for log entries at or above the configured log level.
- slog.Handler.WithGroup and WithAttrs correctly namespace and nest structured fields within Zap log entries.
- zapfield.Str and zapfield.Strs construct type-safe zap.Field instances for custom string types and string slices.
