//! Fork diff/promote engine and background maintenance for uni-db.
//!
//! This crate holds the reusable *logic* of the uni-db fork subsystem:
//!
//! - [`types`] — the public diff/promote value types (`ForkDiff`,
//!   `PromotePattern`, `PromoteReport`, …).
//! - [`diff`] — [`compute_diff`] and [`run_promote`], generic over the
//!   [`host`] traits.
//! - [`host`] — `ForkQueryHost` / `ForkPromoteSink`, implemented by uni-db for
//!   its `Session`/`Transaction` types.
//! - [`maintenance`] — the TTL sweeper and fork-local index-builder task
//!   skeletons, generic over `maintenance::ForkMaintenanceHost`.
//!
//! The fork *drivers* that construct `Session`/`UniInner` (`fork.rs`,
//! `fork_schema.rs`, the `Uni::*` fork orchestration) stay in uni-db to avoid a
//! dependency cycle; they delegate to this crate's engine.
