Scalability / Simplicity
Kind: tension
Record: tension:scalability-simplicity
Canonical: Schema
"scalability" (performance-core layer) is traded against "Simplicity" (human-factors layer) — a principle cannot be scope-separated from a quality, metric, or cost it competes with; resolve by measuring "Simplicity" and choosing an explicit operating point.
