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
