Prototype Pattern / Copy Semantics
Kind: tension
Record: tension:copy-semantics-prototype-pattern
Canonical: Schema
"prototype-pattern" (design-patterns-core layer) is traded against "Copy Semantics" (design-patterns-core layer) — a principle cannot be scope-separated from a quality, metric, or cost it competes with; resolve by measuring "Copy Semantics" and choosing an explicit operating point.
Listed in Tensions, after Builder Pattern / Boilerplate and before Singleton Pattern / Testability.
