//! VSR (Viewstamped Replication) consensus wire types.
//!
//! All headers are exactly 256 bytes with `#[repr(C)]` layout. Size is
//! enforced at compile time. Deserialization is a pointer cast (zero-copy)
//! via `bytemuck::try_from_bytes`.
//!
//! ## Client-facing
//! - [`RequestHeader`] - client -> primary
//! - [`ReplyHeader`] - primary -> client
//! - [`GenericHeader`] - type-erased envelope for dispatch
//!
//! ## Replication (server-to-server)
//! - [`PrepareHeader`] - primary -> replicas (replicate operation)
//! - [`PrepareOkHeader`] - replica -> primary (acknowledge)
//! - [`CommitHeader`] - primary -> replicas (commit, header-only)
//!
//! ## View change (server-to-server)
//! - [`StartViewChangeHeader`] - replica suspects primary failure (header-only)
//! - [`DoViewChangeHeader`] - replica -> primary candidate (header-only)
//! - [`StartViewHeader`] - new primary -> all replicas (header-only)
