Inversion of Control (IoC) / Traceability
Kind: tension
Record: tension:inversion-of-control-ioc-traceability
Canonical: Schema
"inversion-of-control" (extensibility-core layer) is traded against "Traceability" (observability layer) — a principle cannot be scope-separated from a quality, metric, or cost it competes with; resolve by measuring "Traceability" and choosing an explicit operating point.
