1//! State management for InferaDB Ledger.
2//!
3//! This crate sits between the raw B+ tree storage engine (`inferadb-ledger-store`)
4//! and the Raft consensus layer (`inferadb-ledger-raft`), providing:
5//!
6//! - State layer with bucket-based incremental hashing (256 buckets per vault)
7//! - Entity and relationship CRUD with conditional writes
8//! - Snapshot creation and restoration
9//! - Dual indexes for relationship queries (object-centric and subject-centric)
10//! - System types for routing and cluster membership
11//! - Time-travel index for historical queries
12//! - Block archive for committed block storage
