Internal Raft API

Service: astraraftpb.InternalRaft

Methods:

RPC	Purpose
AppendEntries	Replication and heartbeat transport between peers.
Vote	Election request/response transport.
InstallSnapshot	Snapshot transfer transport.

Each RPC uses RaftBytes with one field:

• payload: bytes (opaque openraft transport envelope)

Operational Constraints

• This API is peer-only and must not be exposed as a public client surface.
• Payload compatibility is tied to Astra/openraft runtime versions in the same cluster.
• Authentication/authorization for peer plane is expected to be handled by network boundary controls.

This surface is internal and not intended for external client integration.
