Benchmarking / Environment Drift
Kind: tension
Record: tension:benchmarking-environment-drift
Canonical: Schema
"benchmarking" (performance-core layer) is traded against "Environment Drift" (performance-core layer) — a principle cannot be scope-separated from a quality, metric, or cost it competes with; resolve by measuring "Environment Drift" and choosing an explicit operating point.
