Stable Interfaces / Evolution Speed
Kind: tension
Record: tension:evolution-speed-stable-interfaces
Canonical: Schema
"stable-interfaces" (contracts-core layer) is traded against "Evolution Speed" (contracts-core layer) — a principle cannot be scope-separated from a quality, metric, or cost it competes with; resolve by measuring "Evolution Speed" and choosing an explicit operating point.
