Choreography / Traceability
Kind: tension
Record: tension:choreography-traceability
Canonical: Schema
"choreography" (execution-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.
