Modularity / Cross-Cutting Concerns
Kind: tension
Record: tension:cross-cutting-concerns-modularity
Canonical: Schema
"modularity" (structural-core layer) is traded against "Cross-Cutting Concerns" (structural-core layer) — a principle cannot be scope-separated from a quality, metric, or cost it competes with; resolve by measuring "Cross-Cutting Concerns" and choosing an explicit operating point.
