Interchangeability / Specialized Optimization
Kind: tension
Record: tension:interchangeability-specialized-optimization
Canonical: Schema
"interchangeability" (structural-core layer) is traded against "Specialized Optimization" (structural-core layer) — a principle cannot be scope-separated from a quality, metric, or cost it competes with; resolve by measuring "Specialized Optimization" and choosing an explicit operating point.
