Crash-fault consensus and quorum reasoning: FLP, safety versus liveness, majority 2f+1, R + W > N intersection and its limits, voter/failure-domain placement, Raft terms and why external fencing still requires resource enforcement, plus the differing read/watch contracts of etcd, ZooKeeper and Consul. Use when a cluster size is being chosen, when nodes are spread across AZs or regions, when application data or a queue is being put in etcd or ZooKeeper, when a coordination store sits on the…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Consensus And Quorums ## Purpose Consensus is a set of processes agreeing on **one value** with safety despite modeled crashes, loss and delay; progress additionally needs a quorum and timing assumptions such as eventual synchrony. Consensus can order a replicated log used for grants and configuration, but is not itself a lock or lease. Leases, locks, role election and shard ownership have distinct contracts; not every election uses a lease, and ownership can change dynamically. Route external stale-owner safety to `distributed-locks-and-leases` and role lifecycle to `leader-election`. The failure this prevents is a coordination store used as a traffic-scaled database. etcd, ZooKeeper and Consul are replicated metadata/coordination stores with different read contracts; writes pass through a leader/quorum log and durable storage, often batched/pipelined. Business rows, a work queue or a per-request job table in one makes every business write a consensus decision — and puts the store's availability in series with the service's, which is the arithmetic in `failure-models`. ## Workflow This skill is protocol-level and has no Java language minimum. For a Java integration inspect …

How to install
mdr add robsonkades/agent-skills/consensus-and-quorums@sha256:2c576d0ca784f59fThe line at the top of this page pins the label git:20261016.c769bd8, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
