+# `obidefault` Package — Semantic Overview
+
+This minimal Go package provides a centralized, mutable global flag for controlling warning verbosity across an application.
+
+## Core Functionality
+
+- **`__silent_warning__`**:  
+  A package-level boolean variable (unexported) that determines whether warnings should be suppressed.
+
+- **`SilentWarning() bool`**:  
+  A read-only accessor returning the current state of `__silent_warning__`. Enables safe, non-mutating checks elsewhere in the codebase.
+
+- **`SilentWarningPtr() *bool`**:  
+  Returns a pointer to `__silent_warning__`, allowing external code (e.g., CLI parsers, config loaders) to directly mutate the flag — e.g., `*SilentWarningPtr() = true`.
+
+## Design Intent
+
+- **Simplicity & Centralization**:  
+  Avoids scattering warning-control logic; provides a single source of truth.
+
+- **Flexibility**:  
+  Supports both *read-only* inspection (via `SilentWarning()`) and *global mutation* (via pointer), useful for early initialization phases.
+
+- **Explicit Semantics**:  
+  When `SilentWarning()` returns `true`, all warning-generating code *should* suppress output (implementation responsibility lies outside this package).
+
+## Usage Example
+
+```go
+// Suppress warnings globally:
+*obidefault.SilentWarningPtr() = true
+
+if !obidefault.SilentWarning() {
+    log.Println("⚠️ Warning: something happened")
+}
+```
+
+> **Note**: The double underscore prefix on `__silent_warning__` signals internal/private status, discouraging direct access.
