 - This constructor simply packages the supplied fields into one public snapshot value.
 - It does not inspect a live logger instance by itself.
 - `AsyncLogger::state()` is the higher-level API that reads these values from a concrete logger.
+- It also does not validate whether the supplied fields represent a combination that could come from one real logger instant.
 - The constructed value matches the same public shape used by async logger serializers.
 
 ### How to Use

 - If callers want a snapshot directly from one live logger instance, `AsyncLogger::state()` is the simpler API.
 
+- If callers manually combine a runtime snapshot, counters, or flush policy that do not actually belong together, the constructor still accepts that synthetic snapshot.

 ### Notes
 
 1. Use this helper when code should construct an `AsyncLoggerState` value explicitly.
 
 2. Pair it with `async_logger_state_to_json(...)` or `stringify_async_logger_state(...)` when the snapshot should be exported.
+
+3. Prefer `AsyncLogger::state()` when the goal is to report the actual current state of one live logger instance.
