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.

HOW- Goal
- Intercept, rewrite, and suppress source locations, built-in attributes, and hierarchical group fields using tint.Options.ReplaceAttr

Contract
- tint.NewTextHandler formats source code locations directly between the level badge and log message as a faint prefix instead of a trailing key-value pair, and allows complete suppression or replacement via ReplaceAttr
- ReplaceAttr receives *slog.Source for slog.SourceKey and returning an empty slog.Attr removes the source prefix completely without leftover spacing
- ReplaceAttr intercepts built-in slog keys including slog.LevelKey, slog.MessageKey, and slog.TimeKey for custom level tagging, payload rewriting, or timestamp omission
- Nested WithGroup handlers and inline slog.Group attributes pass their full group hierarchy to ReplaceAttr while tint formats keys with dot notation and prunes empty groups entirely
- ReplaceAttr can dynamically return tint.Attr or tint.Err to conditionally colorize attributes based on runtime values
