LeaseGuard: Raft Leases Done Right
Summary: LeaseGuard: a Raft-specific lease protocol with a crisp TLA+ spec, built on election guarantees rather than ad hoc timing assumptions. Cuts consistent reads from 1 RTT to 0, removes read/write contention, and adds failover optimizations for fast write recovery and near-immediate read availability.
