This release introduces Store-isolated Gateway, Engine and Worker roles and the URI-only protocol. Pair it with sink-go v0.8.0.

Breaking deployment change: deploy a new cluster with new Kafka topics and consumer groups, then cut clients over together. Existing mutation envelopes and scan checkpoints are not migration inputs. Follow the new-cluster migration guide.

  • Gateway owns static Store routing and stable record affinity. Each Engine and Worker binds to one Store, isolating its backend and processing resources.
  • Canonical record/native resource URIs replace old address fields; Store names are the sole routing identity, and MongoDB native operations support collection-bound resources.
  • HTTP health uses a dedicated port independently of opt-in Prometheus. Shutdown now withdraws HTTP readiness before background work and accepted RPCs drain.
  • Gateway removes unnecessary single-owner hashing and single-group goroutine fanout while preserving affinity mapping across versions.
  • Adds real DNS withdrawal/cache/outage counterexamples, graceful and forced drain regressions, Worker 1→3→0→1 qualification, MongoDB election/majority-loss tests and a fixed-resource workload matrix.

The rollout guide explains why DNS refresh alone is insufficient: cache lifetime, discovery failure, retained requests and the complete process shutdown budget all matter. The backend environment guide records the MongoDB/kernel compatibility constraint reproduced during qualification.
