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
- Caddy's filter log encoder module (caddy.logging.encoders.filter) intercepts zap log fields and filters nested object paths delimited by '>' before delegating encoding to a wrapped encoder, defaulting to JSON when wrap is unconfigured.
- The filter encoder module is registered under ID caddy.logging.encoders.filter and instantiates as *logging.FilterEncoder implementing zapcore.Encoder with value-receiver cloning.
- Field filters configured under nested paths such as request>headers>Authorization delete, replace, and mask target fields while preserving unaffected sibling fields.
- Caddyfile unmarshaling parses filter blocks supporting custom wrapped encoders like console along with nested field transformation rules.
