//! Typed command consistency, prepared completions, and portable client effects.
//!
//! This module deliberately separates declaration from durable completion. A
//! handler may prepare a typed payload, but it cannot choose which projection
//! confirmations count. That finite plan belongs to the command declaration,
//! and only the framework-owned command-ledger committer may turn a preparation into
//! an [`Succeeded`], [`Eventual`], or [`Atomic`] value.
