Runtime Extensibility / Predictability
Kind: tension
Record: tension:predictability-runtime-extensibility
Canonical: Schema
"runtime-extensibility" (extensibility-core layer) is traded against "Predictability" (computation-core layer) — a principle cannot be scope-separated from a quality, metric, or cost it competes with; resolve by measuring "Predictability" and choosing an explicit operating point.
