Design Distributed Consensus
Design Distributed Consensus — A Staff playbook focused on when to use consensus, consistency primitive selection, operational cost of Raft/Paxos, and minimizing the consensus domain — not just algorithm explanation.
This playbook is part of the full calibration library.
