Consensus / Latency
Kind: tension
Record: tension:consensus-latency
Canonical: Schema
"consensus" (execution-core layer) is traded against "Latency" (performance-core layer) — a principle cannot be scope-separated from a quality, metric, or cost it competes with; resolve by measuring "Latency" and choosing an explicit operating point.
Listed in Tensions, after Leader Election / Availability and before Consensus / Availability.
