# Runtime Discovery / Startup Cost

> "runtime-discovery" (extensibility-core layer) is traded against "Startup Cost" (extensibility-core layer) — a principle cannot be scope-separated from a quality, metric, or cost it competes with; resolve by measuring "Startup Cost" and choosing an explicit operating point.
