-//! # Usage
+//! **Note (2026-03-27 audit)**: In the Tauri desktop deployment, this module is
+//! NOT wired into the Kernel. The intelligence_hooks module in desktop/src-tauri
+//! provides the same functionality (memory retrieval, heartbeat, reflection) via
+//! direct VikingStorage calls. GrowthIntegration remains available for future
+//! use (e.g., headless/server deployments where intelligence_hooks is not available).
 //!
-//! ```rust,ignore
-//! use zclaw_runtime::growth::GrowthIntegration;
-//! use zclaw_growth::{VikingAdapter, MemoryExtractor, MemoryRetriever, PromptInjector};
-//!
-//! // Create growth integration
-//! let viking = Arc::new(VikingAdapter::in_memory());
-//! let growth = GrowthIntegration::new(viking);
-//!
-//! // Before conversation: enhance system prompt
-//! let enhanced_prompt = growth.enhance_prompt(&agent_id, &base_prompt, &user_input).await?;
-//!
-//! // After conversation: extract and store memories
-//! growth.process_conversation(&agent_id, &messages, session_id).await?;
-//! ```
+//! The `AgentLoop.growth` field defaults to `None` and the code gracefully falls
+//! through to normal behavior when not set.
