-//! Entity caching for various AT Protocol objects
-//!
-//! This is the ONLY approved way to get hydrated data in the application.
-//! Direct hydration through StatefulHydrator should be avoided to ensure
-//! all data access goes through the cache.
-//!
-//! ## Usage
-//!
-//! Instead of:
-//! ```
-//! let hydrator = StatefulHydrator::new(...);
-//! let profile = hydrator.hydrate_profile_detailed(did).await;  // ❌ Bypasses cache!
-//! ```
-//!
-//! Always use:
-//! ```
-//! let profile = profile_cache.get_or_hydrate(actor_id, did, &hydrator).await;  // ✅ Uses cache!
-//! ```
-//!
-//! ## Cache Strategy
-//!
-//! We cache the expensive "Detailed" variants:
-//! - `ProfileViewDetailed` - Full profile with counts, used in getProfile
-//! - `PostView` - Full post with stats, embeds, and viewer state
-//! - `GeneratorView`, `ListView`, etc. - Full entities with all metadata
-//!
-//! Cache invalidation is handled by database triggers via pg_notify.
