Explicitly out of scope for open source

• mTLS on the Raft transport (https://github.com/rustls/rustls); authn for SQL control functions.
• Metrics (Prometheus) + structured logs
• Sharding / write scale-out (that’s Citus).
• Backups / PITR (use pgBackRest / wal-g).
• Logical or multi-master replication.

Validation targets

• Raft consensus node loss acceptance with automatic failover with 0 messages lost.
• Quorum-sync mode: zero committed-transaction loss across induced failovers.
• A newly created role/DDL on the primary is present on a freshly promoted node.
• Resident memory overhead of the bgworker: single-digit MB beyond Postgres.
