 ### 6. Stderr Client Uses All Namespaces
 The built-in stderr client (created in `init()`) listens to all namespaces:
 ```go
-stderrClient = CreateClient(DefaultNamespace)
+stderrClient = CreateClient() // No args = all namespaces
 ```
 
-But only prints logs matching its own namespace in `logStdErr()`:
+It prints logs matching its level and namespace filter in `logStdErr()`:
 ```go
 if e.level >= c.LogLevel && c.matchesNamespace(e.Namespace) {
     fmt.Fprintf(os.Stderr, "%s\t%s\t[%s]\t%s\t%s\n", ...)
 }
 ```
 
-**Wait, that's a bug!** The stderr client is created with `DefaultNamespace` but should be created with no namespaces to see all logs. Let me check this.

-Actually looking at the code:
-```go
-stderrClient = CreateClient(DefaultNamespace)

-
-This means stderr client only sees "default" namespace logs. This might be intentional, but seems like a bug. Should probably be:
-```go
-stderrClient = CreateClient() // No args = all namespaces
-```
+Since `CreateClient()` is called with no arguments, the Namespaces slice is empty, which means it matches all namespaces.
