 //! Provides a persistence-backed store for learnings extracted from agent runs.
 //! Learnings are shared across agents to improve reliability and efficiency.
 //!
-//! Uses `terraphim_persistence` for storage, following the same pattern as
-//! `metrics_persistence` — a trait with in-memory and device-storage implementations.
+//! Two trait layers:
+//! - `LearningPersistence` (async, internal) — direct DeviceStorage interaction
+//! - `terraphim_types::shared_learning::LearningStore` (sync, public) — shared
+//!   contract with `terraphim_agent`
 //!
 //! # Architecture

 //! ```text
-//! Flow State Parser (Python)

+//!     ↓ impl on SharedLearningStore
 //! SharedLearningStore
-//!     ↓ LearningPersistence trait

-//! # Trust Levels

-//! - **L0**: Unverified — just extracted, not yet shown to agents
-//! - **L1**: Verified once — passed verify_pattern or one effective application
-//! - **L2**: Verified multiple times — candidate for Gitea wiki sync
-//! - **L3**: Golden — manually verified, always included in context
