Pattern Consistency / Local Optimization
Kind: tension
Record: tension:local-optimization-pattern-consistency
Canonical: Schema
"pattern-consistency" (evolution-principles layer) is traded against "Local Optimization" (evolution-principles layer) — a principle cannot be scope-separated from a quality, metric, or cost it competes with; resolve by measuring "Local Optimization" and choosing an explicit operating point.
