spacedb-replica 0.1.0

SpaceDB Layer 2 (hot path) — live convergence between replicas: the anti-entropy sync protocol over a Transport seam, with an in-process transport (and partition switch) for testing. MATA implements the transport over iroh+relay; a self-hoster can implement it over iroh directly. Phase 1 SpaceDB Mission, M3.

spacedb-replica — SpaceDB Layer 2 (hot path)

Live convergence between replicas of a document. M3-S1 ships the anti-entropy sync protocol ([SyncSession]) over a transport seam ([Transport]), plus an [InProcessTransport] with a partition switch so the protocol is fully provable in one process.

The protocol reconciles by exchanging state vectors and the deltas they imply (built on spacedb-crdt's sync primitives), so a write on one replica reaches another live, and a partitioned link recovers with zero lost writes simply by announcing again after it heals.

Open-core boundary

Transport is where the network lives. This crate depends only on spacedb-crdt; MATA implements Transport over its iroh + relay + roster-auth stack (mata-sync), and a self-hoster can implement it over plain iroh. No MATA crate is referenced here.
