Traceability / Metadata Propagation Overhead
Kind: tension
Record: tension:metadata-propagation-overhead-traceability
Canonical: Schema
"traceability" (observability layer) is traded against "Metadata Propagation Overhead" (observability layer) — a principle cannot be scope-separated from a quality, metric, or cost it competes with; resolve by measuring "Metadata Propagation Overhead" and choosing an explicit operating point.
