//! Concurrency primitives.
//!
//! `HybridLatch` is a 3-mode latch held per blob frame. The
//! contract follows LeanStore (Leis et al., ICDE 2018).
//! `CommitGate` is the writer-shared / checkpoint-exclusive
//! publish barrier for persistent trees. `Gate` is the small
//! shared/exclusive admission primitive used for tree-wide
//! structural maintenance.
