syncular-client 0.39.1

//! # syncular-client — Syncular v2 Rust client core (POC stage 2)
//!
//! A clean-room client implementation of the SPEC.md client-behavior
//! contract on rusqlite local storage, consuming the committed `ssp2`
//! codec as its wire layer. Built without reading the v1 Rust tree or the
//! v2 TypeScript client — the conformance catalog (packages/conformance)
//! is the proof that both cores implement one written protocol.
//!
//! Blocking hosts drive `sync()` / `sync_until_idle()`. Mailbox hosts prepare
//! a round on the owner, run `PreparedSyncRound::exchange` on an I/O executor,
//! and apply the result on the owner. An upload continuation repeats that
//! exchange/apply cycle before the captured metadata request. The owner can
//! serve local commands throughout; it queues inbound realtime traffic until
//! the round completes. Scheduling is host policy (§8.4).
