-`LoggerConfig` is the public top-level serializable config type used to describe sync logger behavior. It is a direct alias to the logger config model used by config parsers, sync logger builders, and async build config embedding.
+`LoggerConfig` is the public top-level serializable config type used to describe sync logger behavior. On the root `src` facade, it is re-exported from `src/config_model`, which is the real owner of the concrete logger config model.

 Detailed rules explaining key parameters and behaviors
 
-- This is a type alias, not a built logger instance.
+- This root surface is a re-export, not the concrete owner definition.
+- The concrete type lives in `@config_model.LoggerConfig`, not in `@utils`.
 - The current fields are `min_level : Level`, `target : String`, `timestamp : Bool`, `sink : SinkConfig`, and `queue : QueueConfig?`.
 - `LoggerConfig::new(...)` constructs this type as the main sync config entry point.
 - `parse_logger_config_text(...)`, `logger_config_to_json(...)`, `stringify_logger_config(...)`, and `build_logger(...)` all consume or produce the same public config shape.
