//! Stateful in-memory holders. Each owns its `RwLock` and exposes a
//! behaviour-shaped API (insert, remove, evict, query).
//!
//! [`state::MempoolState`] aggregates four locked buckets:
//!
//! - [`tx_store::TxStore`] - full `Transaction` data for live txs.
//! - [`addr_tracker::AddrTracker`] - per-address mempool stats.
//! - [`entry_pool::EntryPool`] - slot-recycled [`TxEntry`](crate::TxEntry)
//!   storage indexed by [`entry_pool::TxIndex`].
//! - [`tx_graveyard::TxGraveyard`] - recently-dropped txs as
//!   [`tx_graveyard::TxTombstone`]s, retained for reappearance
//!   detection and post-mine analytics.
//!
//! A fifth bucket, `info`, holds a `MempoolInfo` from `brk_types`,
//! so it has no file here.
