High Cohesion / Over-Specialization
Kind: tension
Record: tension:high-cohesion-over-specialization
Canonical: Schema
"high-cohesion" (structural-core layer) is traded against "Over-Specialization" (structural-core layer) — a principle cannot be scope-separated from a quality, metric, or cost it competes with; resolve by measuring "Over-Specialization" and choosing an explicit operating point.
