3//! 2026-09-25: Paging core of the SSM snapshot tier: the peer's TCP control protocol
4//! and paging loops, the client side of that protocol (`wire`), and `MmapSlotArena`
5//! (`mmap_arena`). Re-exports the generic `tier` types it builds on.
6//!
7//! Owner: storage, SSM snapshot tier.
8//! Invariants: none beyond the types.
9//!
10//! The peer runs a `Residency` over its RDMA-registered arena and an NVMe swap file,
11//! and owns residency, so every client of one arena shares its cache. The paging
12//! loops register no memory: blobs move between arena and swap under the rkeys each
13//! connection registered in its handshake.
