+// When to use CHECK_RETURN_IF vs CHECK_RETURN_BEGIN/END:
+//
+// CHECK_RETURN_IF:
+// - Simple error checks with no cleanup needed (90% of cases)
+// - Input validation: CHECK_RETURN_IF(argc < 2, 1, "Too few arguments")
+// - Null checks: CHECK_RETURN_IF(ptr == nullptr, nullptr, "Not found: %s", name)
+// - Range checks: CHECK_RETURN_IF(x < 0 || x > max, -1, "Out of range")
+//
+// CHECK_RETURN_BEGIN/END:
+// - Error checks that need cleanup before return (10% of cases)
+// - Free memory: delete[] buffer
+// - Set output params: if (out_size) *out_size = 0
+// - Release resources: close(fd), fclose(file)
+//
+// WARN_IF:
+// - Non-critical issues that don't prevent execution
+// - Deprecated features, missing optional config
+// - Example: WARN_IF(config_missing, "Using default config")
+//
+// ==============================================================================
+// Examples
+// ==============================================================================
+//
+// Simple validation:
+// CHECK_RETURN_IF(name == nullptr, false, "Invalid name parameter");
+//
+// With cleanup:
+// CHECK_RETURN_BEGIN(!buffer, nullptr)
+// if (out_size) *out_size = 0;
+// ERROR_MSG("Failed to allocate %d bytes", size);
+// CHECK_RETURN_END
+//
+// Warning:
+// WARN_IF(file_not_found, "Config file missing, using defaults");
+//
+// ==============================================================================
+// Comparison with FATAL_XXX
+// ==============================================================================
+//
+// Use FATAL_XXX for:
+// - Programming errors (assertion failures, invariant violations)
+// - Corrupted state that cannot be recovered
+// - Internal consistency checks
+// - Example: FATAL_CHECK(idx >= size, "Index out of bounds: %d >= %d", idx, size)
+//
+// Use CHECK_RETURN for:
+// - Recoverable errors (invalid input, missing files)
+// - Runtime configuration issues
+// - API parameter validation
+// - Example: CHECK_RETURN_IF(file == nullptr, false, "File not found: %s", path)
+//
+// Key difference:
+// - FATAL_XXX: abort() - program terminates
+// - CHECK_RETURN: return error_value - caller can handle error
