Encapsulation / Debuggability
Kind: tension
Record: tension:debuggability-encapsulation
Canonical: Schema
"encapsulation" (structural-core layer) is traded against "Debuggability" (observability layer) — a principle cannot be scope-separated from a quality, metric, or cost it competes with; resolve by measuring "Debuggability" and choosing an explicit operating point.
