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
- Handle pino child logger option traps where serializers prototype-merge and apply to bindings immediately, child redact completely replaces parent redactions without merging, levels dynamically track the parent until severed, and messageKey, nestedKey, base, hooks, and level formatters on child are silently ignored

Contract
- assert child serializers prototype-inherit from parent and serialize child bindings immediately at child creation
- assert child redact option completely replaces parent redaction rules instead of merging with them
- assert child loggers dynamically track parent level changes until an explicit level is configured or assigned
- assert messageKey, nestedKey, base, hooks, and formatters.level set on child options are silently ignored in favor of root configuration
