Metadata-Driven Design / Debuggability
Kind: tension
Record: tension:debuggability-metadata-driven-design
Canonical: Schema
"metadata-driven-design" (declarative-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.
