//! Negentropy Catchup Service for GRASP-02 Phase 5
//!
//! Implements gap-filling synchronization to ensure no events are missed during:
//! - Startup (initial sync after warm-up period)
//! - Reconnection (after connection restore)
//! - Daily maintenance (periodic full reconciliation)
//!
//! ## Note on NIP-77
//!
//! This implementation uses a simplified gap-filling strategy (fetch and compare)
//! rather than full NIP-77 negentropy set reconciliation. The nostr-sdk 0.44 does
//! not include built-in negentropy support, so we implement an equivalent approach:
//!
//! 1. Fetch events from relay using same filters as live sync
//! 2. Compare with local database (skip already-stored events)
//! 3. Validate and store missing events through policy
//!
//! Full NIP-77 support can be added in a future release if needed.
