Kind: tension

Record: tension:event-driven-architecture-strong-consistency

Canonical: Schema

"event-driven-architecture" (execution-core layer) is traded against "Strong Consistency" (execution-core layer) — a principle cannot be scope-separated from a quality, metric, or cost it competes with; resolve by measuring "Strong Consistency" and choosing an explicit operating point.
