LogRecord fields
Reference table of every field on the LogRecord dataclass — type, optionality, semantics, ownership, wire encoding.
Severity reference table
Full 24-row enumeration of severity_number values, the canonical severity_text bucket, and the mapping to syslog, Python logging, and Go slog.
Error model
How the logger reports configuration and emit failures — exceptions raised by configure(), exceptions swallowed inside emit(), and the diagnostic channel.
