Expand description
The Syncular v2 Rust client core (SPEC.md client-behavior contract): rusqlite local storage, §3.2/§3.3 effective-scope persistence + purge, §4 pull/cursor/bootstrap (§4.7 resume, §5.6 segment application), §6 push with outbox order, §7 optimistic apply / rollback / replay-on-top, §2.3 clientCommitId idempotency, §8 realtime client rules, §10 errors.
Built from SPEC.md and the committed ssp2 codec alone — no
reference to the v1 Rust tree or the v2 TypeScript client.
